stated in the BDS.

13.2. (a) Unless otherwise stated in the BDS, all Bids that exceed the EPC shall
not be accepted.

(b) Unless otherwise indicated in the BDS, for foreign-funded

procurement, a ceiling may be applied to bid prices provided the following conditions

required by the procuring entity, payment could be made upon
the submission of bids.

(ii) The procuring entity has procedures in place to ensure that the

responsible unit of the procuring entity and that the estimates are
based on adequate detailed engineering (in the case of
infrastructure projects) and reflect the quality, supervision and
risk and inflationary factors, as well as prevailing market prices,
associated with the types of works or goods to be procured.

(iii) The procuring entity has trained cost estimators on estimating

prices and analyzing bid variances. In the case of infrastructure
projects, the procuring entity must also have trained quantity
surveyors.

(iv) The procuring entity has established a system to monitor and

21
14. Alternative Bids
14.1. Alternative Bids shall be rejected. For this purpose, alternative bid is an offer
made by a Bidder in addition or as a substitute to its original bid which may be
included as part of its original bid or submitted separately therewith for purposes
of bidding. A bid with options is considered an alternative bid regardless of
whether said bid proposal is contained in a single envelope or submitted in two
(2) or more separate bid envelopes.

14.2. Bidders shall submit offers that comply with the requirements of the Bidding
Documents, including the basic technical design as indicated in the drawings
and specifications. Unless there is a value engineering clause in the BDS,
alternative bids shall not be accepted.

14.3. Each Bidder shall submit only one Bid, either individually or as a partner in a
JV. A Bidder who submits or participates in more than one bid (other than as a
subcontractor if a subcontractor is permitted to participate in more than one bid)
will cause all the proposals with the Bidder’s participation to be disqualified.
This shall be without prejudice to any applicable criminal, civil and
administrative penalties that may be imposed upon the persons and entities
concerned.

15. Bid Prices

15.1. The contract shall be for the whole Works, as described in ITB Clause 1.1, based
on the priced Bill of Quantities submitted by the Bidder.

15.2. The Bidder shall fill in rates and prices for all items of the Works described in
the Bill of Quantities. Bids not addressing or providing all of the required items
in the Bidding Documents including, where applicable, Bill of Quantities, shall
be considered non-responsive and, thus, automatically disqualified. In this
regard, where a required item is provided, but no price is indicated, the same
shall be considered as non-responsive, but specifying a zero (0) or a dash (-) for
the said item would mean that it is being offered for free to the Government,
except those required by law or regulations to be provided for.

15.3. All duties, taxes, and other levies payable by the Contractor under the Contract,
or for any other cause, prior to the deadline for submission of bids, shall be
included in the rates, prices, and total bid price submitted by the Bidder.

15.4. All bid prices for the given scope of work in the contract as awarded shall be
considered as fixed prices, and therefore not subject to price escalation during
contract implementation, except under extraordinary circumstances as specified
in GCC Clause 48. Upon the recommendation of the Procuring Entity, price
escalation may be allowed in extraordinary circumstances as may be determined
by the National Economic and Development Authority in accordance with the
Civil Code of the Philippines, and upon approval by the GPPB. Furthermore, in
cases where the cost of the awarded contract is affected by any applicable new
laws, ordinances, regulations, or other acts of the GoP, promulgated after the
date of bid opening, a contract price adjustment shall be made or appropriate
relief shall be applied on a no loss-no gain basis.
22
16. Bid Currencies
16.1. All bid prices shall be quoted in Philippine Pesos unless otherwise provided in
the BDS. However, for purposes of bid evaluation, bids denominated in foreign
currencies shall be converted to Philippine currency based on the exchange rate
prevailing on the day of the Bid Opening.

16.2. If so allowed in accordance with ITB Clause 16.1, the Procuring Entity for
purposes of bid evaluation and comparing the bid prices will convert the
amounts in various currencies in which the bid price is expressed to Philippine
Pesos at the exchange rate as published in the Bangko Sentral ng Pilipinas (BSP)
reference rate bulletin on the day of the bid opening.

16.3. Unless otherwise specified in the BDS, payment of the contract price shall be
made in Philippine Pesos.

17. Bid Validity

17.1. Bids shall remain valid for the period specified in the BDS which shall not
exceed one hundred twenty (120) calendar days from the date of the opening of
bids.

17.2. In exceptional circumstances, prior to the expiration of the bid validity period,
the Procuring Entity may request Bidders to extend the period of validity of their
bids. The request and the responses shall be made in writing. The bid security
described in ITB Clause 18 should also be extended corresponding to the
extension of the bid validity period at the least. A Bidder may refuse the request
without forfeiting its bid security, but his bid shall no longer be considered for
further evaluation and award. A Bidder granting the request shall not be required
or permitted to modify its bid.

18. Bid Security

18.1. The Bidder shall submit a Bid Securing Declaration or any form of Bid Security
in an amount stated in the BDS, which shall be not less than the percentage of
the EPC in accordance with the following schedule:

and furnish the performance security required under ITB Clause 32.2, within
ten (10) calendar days from receipt of the Notice of Award, and commits to
pay the corresponding amount as fine, and be suspended for a period of time
from being qualified to participate in any government procurement activity in
the event it violates any of the conditions stated therein as provided in the
guidelines issued by the GPPB.

18.2. The bid security should be valid for the period specified in the BDS. Any bid
not accompanied by an acceptable bid security shall be rejected by the
Procuring Entity as non-responsive.

18.3. No bid securities shall be returned to Bidders after the opening of bids and
before contract signing, except to those that failed or declared as post-
disqualified, upon submission of a written waiver of their right to file a request
for reconsideration and/or protest, or lapse of the reglementary period without
having filed a request for reconsideration or protest. Without prejudice on its
forfeiture, Bid Securities shall be returned only after the Bidder with the
Lowest Calculated Responsive Bid (LCRB) has signed the contract and
furnished the Performance Security, but in no case later than the expiration of
the Bid Security validity period indicated in ITB Clause 18.2.

18.4. Upon signing and execution of the contract, pursuant to ITB Clause 31, and

Submission and Opening, the Bidder’s name, its representative and the time the late bid
was submitted.

23. Modification and Withdrawal of Bids

23.1. The Bidder may modify its bid after it has been submitted; provided that the
modification is received by the Procuring Entity prior to the deadline prescribed
for submission and receipt of bids. The Bidder shall not be allowed to retrieve
its original bid, but shall be allowed to submit another bid equally sealed and
properly identified in accordance with Clause 20, linked to its original bid
marked as “TECHNICAL MODIFICATION” or “FINANCIAL
MODIFICATION” and stamped “received” by the BAC. Bid modifications

forfeiture of the Bidder’s bid security, pursuant to ITB Clause 18.5, and the
imposition of administrative, civil, and criminal sanctions as prescribed by RA
9184 and its IRR.

24. Opening and Preliminary Examination of Bids

24.1. The BAC shall open the Bids in public, immediately after the deadline for the
submission and receipt of bids in public, as specified in the BDS. In case the
Bids cannot be opened as scheduled due to justifiable reasons, the BAC shall
take custody of the Bids submitted and reschedule the opening of Bids on the
next working day or at the soonest possible time through the issuance of a Notice
of Postponement to be posted in the PhilGEPS website and the website of the
Procuring Entity concerned.

24.2. Unless otherwise specified in the BDS, the BAC shall open the first bid
envelopes and determine each Bidder’s compliance with the documents
prescribed in ITB Clause 12, using a non-discretionary “pass/fail” criterion. If a
Bidder submits the required document, it shall be rated “passed” for that
particular requirement. In this regard, bids that fail to include any requirement
or are incomplete or patently insufficient shall be considered as “failed”.
Otherwise, the BAC shall rate the said first bid envelope as “passed”.

24.3. Unless otherwise specified in the BDS, immediately after determining

compliance with the requirements in the first envelope, the BAC shall forthwith
open the second bid envelope of each remaining eligible Bidder whose first bid
envelope was rated “passed.” The second envelope of each complying Bidder
shall be opened within the same day. In case one or more of the requirements in
the second envelope of a particular bid is missing, incomplete or patently
insufficient, and/or if the submitted total bid price exceeds the EPC unless
otherwise provided in ITB Clause 13.2, the BAC shall rate the bid concerned as
“failed.” Only bids that are determined to contain all the bid requirements for
both components shall be rated “passed” and shall immediately be considered
for evaluation and comparison.

24.4. Letters of Withdrawal shall be read out and recorded during bid opening, and
the envelope containing the corresponding withdrawn bid shall be returned to
the Bidder unopened.

24.5. All members of the BAC who are present during bid opening shall initial every
page of the original copies of all bids received and opened.

28
24.6. In the case of an eligible foreign bidder as described in ITB Clause 5, the

equivalent documents, if any, issued by the country of the foreign bidder
concerned, which shall likewise be uploaded and maintained in the PhilGEPS
in accordance with Section 8.5.2 of the IRR.:

a) Registration certificate from the Securities and Exchange Commission

(SEC), Department of Trade and Industry (DTI) for sole proprietorship,
or CDA for cooperatives;

b) Mayor’s/Business permit issued by the local government where the

principal place of business of the Bidder is located; and

c) Audited Financial Statements showing, among others, the prospective

Bidder’s total and current assets and liabilities stamped “received” by
the Bureau of Internal Revenue or its duly accredited and authorized
institutions, for the preceding calendar year which should not be earlier
than two years from the date of bid submission.

24.7. Each partner of a joint venture agreement shall likewise submit the document
required in ITB Clause 12.1(a)(i). Submission of documents required under ITB
Clauses (a)(ii) to 12.1(a)(iv) by any of the joint venture partners constitutes
compliance.

24.8. The Procuring Entity shall prepare the minutes of the proceedings of the bid
opening that shall include, as a minimum: (a) names of Bidders, their bid price
(per lot, if applicable, and/or including discount, if any), bid security, findings
of preliminary examination, and whether there is a withdrawal or modification;
and (b) attendance sheet. The BAC members shall sign the abstract of bids as
read.

24.9. The Bidders or their duly authorized representatives may attend the opening of
bids. The BAC shall ensure the integrity, security, and confidentiality of all
submitted bids. The Abstract of Bids as read and the minutes of the Bid Opening

BAC Secretariat shall notify in writing all Bidders whose bids it has received
through its PhilGEPS-registered physical address or official e-mail address. The
notice shall be issued within seven (7) calendar days from the date of the bid
opening.

29
 E. Evaluation and Comparison of Bids

25. Process to be Confidential

25.1. Members of the BAC, including its staff and personnel, as well as its Secretariat
and TWG, are prohibited from making or accepting any kind of communication
with any Bidder regarding the evaluation of their bids until the issuance of the
Notice of Award, unless otherwise allowed in the case of ITB Clause 26.

25.2. Any effort by a Bidder to influence the Procuring Entity in the Procuring
Entity’s decision in respect of bid evaluation, bid comparison or contract award
will result in the rejection of the Bidder’s bid.

26. Clarification of Bids

To assist in the evaluation, comparison and post-qualification of the bids, the Procuring
Entity may ask in writing any Bidder for a clarification of its bid. All responses to
requests for clarification shall be in writing. Any clarification submitted by a Bidder in
respect to its bid and that is not in response to a request by the Procuring Entity shall
not be considered

27. Detailed Evaluation and Comparison of Bids

27.1. The Procuring Entity will undertake the detailed evaluation and comparison of
Bids which have passed the opening and preliminary examination of Bids,
pursuant to ITB Clause 24, in order to determine the Lowest Calculated Bid.

27.2. The Lowest Calculated Bid shall be determined in two steps:

(a) The detailed evaluation of the financial component of the bids, to establish the
correct calculated prices of the bids; and

(b) The ranking of the total bid prices as so calculated from the lowest to highest.
The bid with the lowest price shall be identified as the Lowest Calculated Bid.

27.3. The Procuring Entity's BAC shall immediately conduct a detailed evaluation of
all bids rated “passed,” using non-discretionary “pass/fail” criterion. The BAC
shall consider the following in the evaluation of bids:

(a) Completeness of the bid. Unless the BDS allows partial bids, bids not
addressing or providing all of the required items in the Schedule of
Requirements including, where applicable, bill of quantities, shall be considered
non-responsive and, thus, automatically disqualified. In this regard, where a
required item is provided, but no price is indicated, the same shall be considered
as non-responsive, but specifying a zero (0) or a dash (-) for the said item would
mean that it is being offered for free to the Procuring Entity, except those
required by law or regulations to be provided for; and

(b) Arithmetical corrections. Consider computational errors and omissions to

enable proper comparison of all eligible bids. It may also consider bid

30
 modifications. Any adjustment shall be calculated in monetary terms to
determine the calculated prices.

27.4. Based on the detailed evaluation of bids, those that comply with the above-
mentioned requirements shall be ranked in the ascending order of their total
calculated bid prices, as evaluated and corrected for computational errors, discounts
and other modifications, to identify the Lowest Calculated Bid. Total calculated bid
prices, as evaluated and corrected for computational errors, discounts and other
modifications, which exceed the EPC shall not be considered, unless otherwise
indicated in the BDS.

27.5. The Procuring Entity’s evaluation of bids shall be based on the bid price quoted in
the Bid Form, which includes the Bill of Quantities.

27.6. Bids shall be evaluated on an equal footing to ensure fair competition. For this
purpose, all Bidders shall be required to include in their bids the cost of all taxes,
such as, but not limited to, value added tax (VAT), income tax, local taxes, and other
fiscal levies and duties which shall be itemized in the bid form and reflected in the
detailed estimates. Such bids, including said taxes, shall be the basis for bid
evaluation and comparison.

27.7. If so indicated pursuant to ITB Clause 1.2. Bids are being invited for individual lots
or for any combination thereof, provided that all Bids and combinations of Bids shall
be received by the same deadline and opened and evaluated simultaneously so as to
determine the bid or combination of bids offering the lowest calculated cost to the
Procuring Entity. Bid prices quoted shall correspond to all of the requirements
specified for each lot. Bid Security as required by ITB Clause 18 shall be submitted
for each contract (lot) separately. The basis for evaluation of lots is specified in BDS
Clause 27.3.

28. Post Qualification

28.1. The BAC shall determine to its satisfaction whether the Bidder that is evaluated
as having submitted the Lowest Calculated Bid complies with and is responsive
to all the requirements and conditions specified in ITB Clauses 5, 12, and 13.

28.2. Within a non-extendible period of five (5) calendar days from receipt by the
Bidder of the notice from the BAC that it submitted the Lowest Calculated Bid,
the Bidder shall submit its latest income and business tax returns filed and paid
through the BIR Electronic Filing and Payment System (eFPS) and other
appropriate licenses and permits required by law and stated in the BDS.

Failure to submit any of the post-qualification requirements on time, or a finding

against the veracity thereof, shall disqualify the Bidder for award. Provided in
the event that a finding against the veracity of any of the documents submitted
is made, it shall cause the forfeiture of the bid security in accordance with
Section 69 of the IRR of RA 9184.

28.3. The determination shall be based upon an examination of the documentary

evidence of the Bidder’s qualifications submitted pursuant to ITB Clauses 12 and
13, as well as other information as the Procuring Entity deems necessary and
31
 appropriate, using a non-discretionary “pass/fail” criterion, which shall be
completed within a period of twelve (12) calendar days.

28.4. information as the Procuring Entity deems necessary and appropriate, using a
non-discretionary “pass/fail” criterion, which shall be completed within a period
of twelve (12) calendar days.

28.5. If the BAC determines that the Bidder with the Lowest Calculated Bid passes all
the criteria for post-qualification, it shall declare the said bid as the LCRB, and
recommend to the HoPE the award of contract to the said Bidder at its submitted
price or its calculated bid price, whichever is lower, subject to ITB Clause 30.3.

28.6. A negative determination shall result in rejection of the Bidder’s bid, in which
event the Procuring Entity shall proceed to the next Lowest Calculated Bid, with
a fresh period to make a similar determination of that Bidder’s capabilities to
perform satisfactorily. If the second Bidder, however, fails the post qualification,
the procedure for post qualification shall be repeated for the Bidder with the next
Lowest Calculated Bid, and so on until the LCRB is determined for
recommendation of contract award.

28.7. Within a period not exceeding fifteen (15) calendar days from the determination
by the BAC of the LCRB and the recommendation to award the contract, the
HoPE or his duly authorized representative shall approve or disapprove the said
recommendation.

28.8. In the event of disapproval, which shall be based on valid, reasonable, and
justifiable grounds as provided for under Section 41 of the IRR of RA 9184, the
HoPE shall notify the BAC and the Bidder in writing of such decision and the
grounds for it. When applicable, the BAC shall conduct a post-qualification of
the Bidder with the next Lowest Calculated Bid. A request for reconsideration
may be filed by the Bidder with the HoPE in accordance with Section 37.1.3 of
the IRR of RA 9184.

29. Reservation Clause

29.1. Notwithstanding the eligibility or post-qualification of a Bidder, the Procuring
Entity concerned reserves the right to review its qualifications at any stage of
the procurement process if it has reasonable grounds to believe that a
misrepresentation has been made by the said Bidder, or that there has been a
change in the Bidder’s capability to undertake the project from the time it
submitted its eligibility requirements. Should such review uncover any
misrepresentation made in the eligibility and bidding requirements, statements
or documents, or any changes in the situation of the Bidder which will affect its
capability to undertake the project so that it fails the preset eligibility or bid
evaluation criteria, the Procuring Entity shall consider the said Bidder as
ineligible and shall disqualify it from submitting a bid or from obtaining an
award or contract.

29.2. Based on the following grounds, the Procuring Entity reserves the right to reject
any and all Bids, declare a Failure of Bidding at any time prior to the contract

32
 award, or not to award the contract, without thereby incurring any liability, and
make no assurance that a contract shall be entered into as a result of the bidding:

(a) If there is prima facie evidence of collusion between appropriate public

officers or employees of the Procuring Entity, or between the BAC and
any of the Bidders, or if the collusion is between or among the Bidders
themselves, or between a Bidder and a third party, including any act
which restricts, suppresses or nullifies or tends to restrict, suppress or
nullify competition;

(b) If the Procuring Entity’s BAC is found to have failed in following the
prescribed bidding procedures; or

(c) For any justifiable and reasonable ground where the award of the
contract will not redound to the benefit of the GOP as follows:

(i) If the physical and economic conditions have significantly

changed so as to render the project no longer economically,
financially or technically feasible as determined by the HoPE;

(ii) If the project is no longer necessary as determined by the HoPE;

and

(iii) If the source of funds for the project has been withheld or
reduced through no fault of the Procuring Entity.

29.3. In addition, the Procuring Entity may likewise declare a failure of bidding when:

(a) No bids are received;

(b) All prospective Bidders are declared ineligible;

(c) All bids fail to comply with all the bid requirements, fail post-
qualification; or

3.1 The World Bank’s Anti-Corruption Policy requires the Borrowers (including
beneficiaries of Bank-financed activity), as well as Bidders, Suppliers, Contractors
and their agents (whether declared or not), sub-contractors, sub-consultants, service
providers or suppliers, and any personnel thereof, observe the highest standard of
ethics during the procurement and execution of Bank-financed contracts. Any action
to influence the procurement process or contract execution for undue advantage is
improper.

In pursuance of this policy, the Bank:

(i) "Corrupt practice" means the offering, giving, receiving, or soliciting, directly or
indirectly, anything of value to influence improperly the actions of another party.
Another party refers to a public official acting in relation to the procurement process
or contract execution. Public official includes World Bank staff and employees of
other organizations taking or reviewing procurement decisions;

(ii) "fraudulent practice" means any act or omission, including a

misrepresentation, that knowingly or recklessly misleads, or attempts to mislead,
a party to obtain a financial or other benefit or to avoid an obligation. The term
"party" refers to a public official; the terms "benefit" and "obligations" relate to
the procurement process or contract execution; and the "act or omission" is
intended to influence the procurement process or contract execution;

(iii) "Coercive practice" means impairing or harming, or threatening to impair or

harm, directly or indirectly, any party or the property of the party to influence
improperly the actions of a party. The term "party" refers to a participant in the
procurement process or contract execution;

(iv) "Collusive practice" means an arrangement between two or more parties

designed to achieve an improper purpose, including influencing improperly the
actions of another party. The term "parties" refers to participants in the
procurement process (including public officials) attempting either themselves, or
through another person or entity not participating in the procurement or selection
process, to simulate competition or establish bid prices at artificial,
noncompetitive levels, or are privy to each other's bid prices or other conditions;

(v) “obstructive practice” is

(aa) deliberately destroying, falsifying, altering, or concealing of evidence

material to the investigation or making false statements to investigators in order
to materially impede a Bank investigation into allegations of a corrupt,
fraudulent, coercive or collusive practice; and/or threatening, harassing or
intimidating any party to prevent it from disclosing its knowledge of matters
relevant to the investigation or from pursuing the investigation, or

(bb) acts intended to materially impede the exercise of the Bank's inspection and
audit rights provided for under paragraph (e) below.

(b) will reject a proposal for award if it determines that the Bidder recommended
for award, or any of its personnel, or its agents, or its sub-consultants, sub-
contractors, service providers, suppliers and/or their employees, has, directly or

38
 indirectly, engaged in corrupt, fraudulent, collusive, coercive, or obstructive
practices or other integrity violations in competing for the Contract in question

(c) will declare mis-procurement and cancel the portion of the financing
allocated to a contract if it determines at any time that representatives of the
Borrower or of a recipient of any part of the proceeds of the financing engaged
in corrupt, fraudulent, collusive, coercive, or obstructive practices during the
procurement or the implementation of the contract in question, without the
Borrower having taken timely and appropriate action satisfactory to Bank to
address such practices when they occur, including by failing to inform the Bank
in a timely manner at the time they knew of the practices;

(d) will sanction a firm or an individual, at any time, in accordance with the
prevailing Bank's sanctions procedures, including by publicly declaring such
firm or individual ineligible, either indefinitely or for a stated period of time: (i)
to be awarded a Bank-financed contract; and (ii) to be a nominated sub-
contractor, consultant, manufacturer or supplier, or service provider (different
names are used depending on the particular bidding document) is one which has
either been (i) included by the bidder in its pre-qualification application or bid
because it brings specific and critical experience and know-how that allow the
bidder to meet the qualification requirements for the particular bid; or (ii)

awarded a Bank financed contract upon (i) completion of the Bank's sanctions

Representative by this Contract or that the decision was wrongly taken, the decision
shall be referred to the Arbiter indicated in the SCC within fourteen (14) days of the
notification of the Procuring Entity’s Representative’s decision.

21.3 Any and all disputes arising from the implementation of this Contract covered
by the R.A. 9184 and its IRR shall be submitted to arbitration in the Philippines
according to the provisions of Republic Act No. 876, otherwise known as the “
Arbitration Law” and Republic Act 9285, otherwise known as the “Alternative Dispute
Resolution Act of 2004”: Provided, however, That, disputes that are within the
competence of the Construction Industry Arbitration Commission to resolve shall be
referred thereto. The process of arbitration shall be incorporated as a provision in this
Contract that will be executed pursuant to the provisions of the Act and its IRR:
Provided, further, That, by mutual agreement, the parties may agree in writing to resort
to other alternative modes of dispute resolution.

22. Suspension of Loan, Credit, Grant, or Appropriation

In the event that the Funding Source suspends the Loan, Credit, Grant, or Appropriation
to the Procuring Entity, from which part of the payments to the Contractor are being
made:

65
 (a) The Procuring Entity is obligated to notify the Contractor of such suspension
within seven (7) days of having received the suspension notice.
(b) If the Contractor has not received sums due it for work already done within forty
five (45) days from the time the Contractor’s claim for payment has been certified by
the Procuring Entity’s Representative, the Contractor may immediately issue a
suspension of work notice in accordance with GCC Clause 45.2.

23. Procuring Entity’s Representative’s Decisions

23.1 Except where otherwise specifically stated, the Procuring Entity’s

Representative will decide contractual matters between the Procuring Entity and the

Representative

25.1 When the Procuring Entity wants the Contractor to finish before the Intended
Completion Date, the Procuring Entity’s Representative will obtain priced proposals
for achieving the necessary acceleration from the Contractor. If the Procuring Entity
accepts these proposals, the Intended Completion Date will be adjusted accordingly and
confirmed by both the Procuring Entity and the Contractor.

25.2 If the Contractor’s Financial Proposals for an acceleration are accepted by the
Procuring Entity, they are incorporated in the Contract Price and treated as a Variation.

26. Extension of the Intended Completion Date

66
 26.1 The Procuring Entity’s Representative shall extend the Intended Completion
Date if a Variation is issued which makes it impossible for the Intended Completion
Date to be achieved by the Contractor without taking steps to accelerate the remaining
work, which would cause the Contractor to incur additional costs. No payment shall be
made for any event which may warrant the extension of the Intended Completion Date.

26.2 The Procuring Entity’s Representative shall decide whether and by how much
to extend the Intended Completion Date within twenty one (21) days of the Contractor
asking the Procuring Entity’s Representative for a decision thereto after fully submitting
all supporting information. If the Contractor has failed to give early warning of a delay
or has failed to cooperate in dealing with a delay, the delay by this failure shall not be
considered in assessing the new Intended Completion Date.

27. Right to Vary

27.1 The Procuring Entity’s Representative with the prior approval of the Procuring
Entity may instruct Variations, up to a maximum cumulative amount of ten percent
(10%) of the original contract cost.

27.2 Variations shall be valued as follows:

(a) At a lump sum price agreed between the parties;

(b) where appropriate, at rates in this Contract;
(c) in the absence of appropriate rates, the rates in this Contract shall be
used as the basis for valuation; or failing which
(d) at appropriate new rates, equal to or lower than current industry rates
and to be agreed upon by both parties and approved by the HoPE.

If the Contractor incurs cost as a result of any of the events under GCC Clause 13, the
Contractor shall be entitled to the amount of such cost. If as a result of any of the said
events, it is necessary to change the Works, this shall be dealt with as a Variation.

29. Dayworks

29.1 Subject to GCC Clause 43 on Variation Order, and if applicable as indicated in

the SCC, the Dayworks rates in the Contractor’s bid shall be used for small additional
amounts of work only when the Procuring Entity’s Representative has given written
instructions in advance for additional work to be paid for in that way.

29.2 All work to be paid for as Dayworks shall be recorded by the Contractor on
forms approved by the Procuring Entity’s Representative. Each completed form shall
be verified and signed by the Procuring Entity’s Representative within two days of the
work being done.

67
 29.3 The Contractor shall be paid for Dayworks subject to obtaining signed
Dayworks forms.

30. Early Warning

30.1 The Contractor shall warn the Procuring Entity’s Representative at the earliest
opportunity of specific likely future events or circumstances that may adversely affect
the quality of the work, increase the Contract Price, or delay the execution of the Works.
The Procuring Entity’s Representative may require the Contractor to provide an
estimate of the expected effect of the future event or circumstance on the Contract Price
and Completion Date. The estimate shall be provided by the Contractor as soon as
reasonably possible.

30.2 The Contractor shall cooperate with the Procuring Entity’s Representative in
making and considering proposals for how the effect of such an event or circumstance
can be avoided or reduced by anyone involved in the work and in carrying out any
resulting instruction of the Procuring Entity’s Representative.

31. Program of Work

31.1 Within the time stated in the SCC, the Contractor shall submit to the Procuring
Entity’s Representative for approval a Program of Work showing the general methods,
arrangements, order, and timing for all the activities in the Works.

31.2 An update of the Program of Work shall show the actual progress achieved on
each activity and the effect of the progress achieved on the timing of the remaining work,
including any changes to the sequence of the activities.

31.3 The Contractor shall submit to the Procuring Entity’s Representative for
approval an updated Program of Work at intervals no longer than the period stated in the
SCC. If the Contractor does not submit an updated Program of Work within this period,
the Procuring Entity’s Representative may withhold the amount stated in the SCC from
the next payment certificate and continue to withhold this amount until the next payment
after the date on which the overdue Program of Work has been submitted.

31.4 The Procuring Entity’s Representative’s approval of the Program of Work shall
not alter the Contractor’s obligations. The Contractor may revise the Program of Work
and submit it to the Procuring Entity’s Representative again at any time. A revised
Program of Work shall show the effect of any approved Variations.

31.5 When the Program of Work is updated, the Contractor shall provide the
Procuring Entity’s Representative with an updated cash flow forecast. The cash flow
forecast shall include different currencies, as defined in the Contract, converted as
necessary using the Contract exchange rates.

31.6 All Variations shall be included in updated Program of Work produced by the
Contractor.
68
32. Management Conferences

32.1 Either the Procuring Entity’s Representative or the Contractor may require the
other to attend a Management Conference. The Management Conference shall review
the plans for remaining work and deal with matters raised in accordance with the early
warning procedure.

32.2 The Procuring Entity’s Representative shall record the business of Management
Conferences and provide copies of the record to those attending the Conference and to
the Procuring Entity. The responsibility of the parties for actions to be taken shall be
decided by the Procuring Entity’s Representative either at the Management Conference
or after the Management Conference and stated in writing to all who attended the
Conference.

33. Bill of Quantities

33.1 The Bill of Quantities shall contain items of work for the construction,
installation, testing, and commissioning of work to be done by the Contractor.
33.2 The Bill of Quantities is used to calculate the Contract Price. The Contractor is
paid for the quantity of the work done at the rate in the Bill of Quantities for each item.

33.3 If the final quantity of any work done differs from the quantity in the Bill of
Quantities for the particular item and is not more than twenty five percent (25%) of the
original quantity, provided the aggregate changes for all items do not exceed ten percent
(10%) of the Contract price, the Procuring Entity’s Representative shall make the
necessary adjustments to allow for the changes subject to applicable laws, rules, and
regulations.

33.4 If requested by the Procuring Entity’s Representative, the Contractor shall

provide the Procuring Entity’s Representative with a detailed cost breakdown of any
rate in the Bill of Quantities.

34. Instructions, Inspections and Audits

34.1 The Procuring Entity’s personnel shall at all reasonable times during
construction of the Work be entitled to examine, inspect, measure and test the materials
and workmanship, and to check the progress of the construction.

34.2 If the Procuring Entity’s Representative instructs the Contractor to carry out a
test not specified in the Specification to check whether any work has a defect and the
test shows that it does, the Contractor shall pay for the test and any samples. If there is
no defect, the test shall be a Compensation Event.

34.3 The Contractor shall permit the Funding Source named in the SCC to inspect
the Contractor’s accounts and records relating to the performance of the Contractor and
69
 to have them audited by auditors appointed by the Funding Source, if so required by the
Funding Source.

35. Identifying Defects

The Procuring Entity’s Representative shall check the Contractor’s work and notify the
Contractor of any defects that are found. Such checking shall not affect the Contractor’s
responsibilities. The Procuring Entity’s Representative may instruct the Contractor to
search uncover defects and test any work that the Procuring Entity’s Representative
considers below standards and defective.

36. Cost of Repairs

Loss or damage to the Works or Materials to be incorporated in the Works between the
Start Date and the end of the Defects Liability Periods shall be remedied by the
Contractor at the Contractor’s cost if the loss or damage arises from the Contractor’s
acts or omissions.

37. Correction of Defects

37.1 The Procuring Entity’s Representative shall give notice to the Contractor of any
defects before the end of the Defects Liability Period, which is One (1) year from project
completion up to final acceptance by the Procuring Entity’s Representative.
37.2 Every time notice of a defect is given, the Contractor shall correct the notified
defect within the length of time specified in the Procuring Entity’s Representative’s
notice.

37.3 The Contractor shall correct the defects which he notices himself before the end
of the Defects Liability Period.

37.4 The Procuring Entity shall certify that all defects have been corrected. If the
Procuring Entity considers that correction of a defect is not essential, he can request the
Contractor to submit a quotation for the corresponding reduction in the Contract Price.
If the Procuring Entity accepts the quotation, the corresponding change in the SCC is a
Variation.

38. Uncorrected Defects

38.1 The Procuring Entity shall give the Contractor at least fourteen (14) days notice
of his intention to use a third party to correct a Defect. If the Contractor does not correct
the Defect himself within the period, the Procuring Entity may have the Defect
corrected by the third party. The cost of the correction will be deducted from the
Contract Price.

38.2 The use of a third party to correct defects that are uncorrected by the Contractor
will in no way relieve the Contractor of its liabilities and warranties under the Contract.

70
39. Advance Payment

39.1 The Procuring Entity shall, upon a written request of the contractor which shall
be submitted as a contract document, make an advance payment to the contractor in an
amount not exceeding fifteen percent (15%) of the total contract price, to be made in
lump sum or, at the most two, installments according to a schedule specified in the
SCC.

39.2 The advance payment shall be made only upon the submission to and
acceptance by the Procuring Entity of an irrevocable standby letter of credit of
equivalent value from a commercial bank, a bank guarantee or a surety bond callable
upon demand, issued by a surety or insurance company duly licensed by the Insurance
Commission and confirmed by the Procuring Entity.

39.3 The advance payment shall be repaid by the Contractor by an amount equal to
the percentage of the total contract price used for the advance payment.

39.4 The contractor may reduce his standby letter of credit or guarantee instrument
by the amounts refunded by the Monthly Certificates in the advance payment.

39.5 The Procuring Entity will provide an Advance Payment on the Contract Price
as stipulated in the Conditions of Contract, subject to the maximum amount stated in
SCC Clause 39.1.

40. Progress Payments

40.1 The Contractor may submit a request for payment for Work accomplished.
Such request for payment shall be verified and certified by the Procuring Entity’s
Representative/Project Engineer. Except as otherwise stipulated in the SCC, materials
and equipment delivered on the site but not completely put in place shall not be included
for payment.

40.2 The Procuring Entity shall deduct the following from the certified gross
amounts to be paid to the contractor as progress payment:

(a) Cumulative value of the work previously certified and paid for.
(b) Portion of the advance payment to be recouped for the month.
(c) Retention money in accordance with the condition of contract.
(d) Amount to cover third party liabilities.
(e) Amount to cover uncorrected discovered defects in the works.

40.3 Payments shall be adjusted by deducting therefrom the amounts for advance
payments and retention. The Procuring Entity shall pay the Contractor the amounts
certified by the Procuring Entity’s Representative within twenty eight (28) days from
the date each certificate was issued. No payment of interest for delayed payments and
adjustments shall be made by the Procuring Entity.

71
 40.4 The first progress payment may be paid by the Procuring Entity to the
Contractor provided that at least twenty percent (20%) of the work has been
accomplished as certified by the Procuring Entity’s Representative.

40.5 Items of the Works for which a price of “0” (zero) has been entered will not be
paid for by the Procuring Entity and shall be deemed covered by other rates and prices
in the Contract.

41. Payment Certificates

41.1 The Contractor shall submit to the Procuring Entity’s Representative monthly
statements of the estimated value of the work executed less the cumulative amount
certified previously.

41.2 The Procuring Entity’s Representative shall check the Contractor’s monthly
statement and certify the amount to be paid to the Contractor.

41.3 The value of Work executed shall:

(a) be determined by the Procuring Entity’s Representative;

(b) comprise the value of the quantities of the items in the Bill of Quantities
completed; and
(c) include the valuations of approved variations.

41.4 The Procuring Entity’s Representative may exclude any item certified in a
previous certificate or reduce the proportion of any item previously certified in any
certificate in the light of later information.

42. Retention

42.1 The Procuring Entity shall retain from each payment due to the Contractor an
amount equal to a percentage thereof using the rate as specified in GCC Sub-Clause
42.2.

42.2 Progress payments are subject to retention of ten percent (10%), referred to as
the “retention money.” Such retention shall be based on the total amount due to the
Contractor prior to any deduction and shall be retained from every progress payment
until fifty percent (50%) of the value of Works, as determined by the Procuring Entity,
are completed. If, after fifty percent (50%) completion, the Work is satisfactorily done
and on schedule, no additional retention shall be made; otherwise, the ten percent (10%)
retention shall again be imposed using the rate specified therefor.

42.3 The total “retention money” shall be due for release upon final acceptance of
the Works. The Contractor may, however, request the substitution of the retention
money for each progress billing with irrevocable standby letters of credit from a
commercial bank, bank guarantees or surety bonds callable on demand, of amounts

72
 equivalent to the retention money substituted for and acceptable to the Procuring Entity,
provided that the project is on schedule and is satisfactorily undertaken. Otherwise, the
ten (10%) percent retention shall be made. Said irrevocable standby letters of credit,
bank guarantees and/or surety bonds, to be posted in favor of the Government shall be
valid for a duration to be determined by the concerned implementing office/agency or
Procuring Entity and will answer for the purpose for which the ten (10%) percent
retention is intended, i.e., to cover uncorrected discovered defects and third party
liabilities.

42.4 On completion of the whole Works, the Contractor may substitute retention
money with an “on demand” Bank guarantee in a form acceptable to the Procuring
Entity.

43. Variation Orders

43.1 Variation Orders may be issued by the Procuring Entity to cover any
increase/decrease in quantities, including the introduction of new work items that are
not included in the original contract or reclassification of work items that are either
due to change of plans, design or alignment to suit actual field conditions resulting in
disparity between the preconstruction plans used for purposes of bidding and the “as
staked plans” or construction drawings prepared after a joint survey by the Contractor
and the Procuring Entity after award of the contract, provided that the cumulative
amount of the Variation Order does not exceed ten percent (10%) of the original
project cost. The addition/deletion of Works should be within the general scope of the
project as bid and awarded. The scope of works shall not be reduced so as to
accommodate a positive Variation Order. A Variation Order may either be in the form
of a Change Order or Extra Work Order.

43.2 A Change Order may be issued by the Procuring Entity to cover any
increase/decrease in quantities of original Work items in the contract.

43.3 An Extra Work Order may be issued by the Procuring Entity to cover the
introduction of new work necessary for the completion, improvement or protection of
the project which were not included as items of Work in the original contract, such as,
where there are subsurface or latent physical conditions at the site differing materially
from those indicated in the contract, or where there are duly unknown physical
conditions at the site of an unusual nature differing materially from those ordinarily
encountered and generally recognized as inherent in the Work or character provided
for in the contract.

43.4 Any cumulative Variation Order beyond ten percent (10%) shall be subject of
another contract to be bid out if the works are separable from the original contract. In
exceptional cases where it is urgently necessary to complete the original scope of
work, the HoPE may authorize a positive Variation Order go beyond ten percent
(10%) but not more than twenty percent (20%) of the original contract price, subject
to the guidelines to be determined by the GPPB: Provided, however, That appropriate
sanctions shall be imposed on the designer, consultant or official responsible for the

73
 original detailed engineering design which failed to consider the Variation Order
beyond ten percent (10%).

43.5 In claiming for any Variation Order, the Contractor shall, within seven (7)
calendar days after such work has been commenced or after the circumstances leading
to such condition(s) leading to the extra cost, and within twenty-eight (28) calendar
days deliver a written communication giving full and detailed particulars of any extra
cost in order that it may be investigated at that time. Failure to provide either of such
notices in the time stipulated shall constitute a waiver by the contractor for any claim.
The preparation and submission of Variation Orders are as follows:

(a) If the Procuring Entity’s representative/Project Engineer believes that a

Change Order or Extra Work Order should be issued, he shall prepare the
proposed Order accompanied with the notices submitted by the Contractor, the
plans therefore, his computations as to the quantities of the additional works
involved per item indicating the specific stations where such works are needed,
the date of his inspections and investigations thereon, and the log book thereof,
and a detailed estimate of the unit cost of such items of work, together with his
justifications for the need of such Change Order or Extra Work Order, and shall
submit the same to the HoPE for approval.
(b) The HoPE or his duly authorized representative, upon receipt of the
proposed Change Order or Extra Work Order shall immediately instruct the
appropriate technical staff or office of the Procuring Entity to conduct an on-
the-spot investigation to verify the need for the Work to be prosecuted and to
review the proposed plan, and prices of the work involved.
(c) The technical staff or appropriate office of the Procuring Entity shall
submit a report of their findings and recommendations, together with the
supporting documents, to the Head of Procuring Entity or his duly authorized
representative for consideration.
(d) The HoPE or his duly authorized representative, acting upon the
recommendation of the technical staff or appropriate office, shall approve the
Change Order or Extra Work Order after being satisfied that the same is
justified, necessary, and in order.
(e) The timeframe for the processing of Variation Orders from the
preparation up to the approval by the Procuring Entity concerned shall not
exceed thirty (30) calendar days.

44. Contract Completion

Once the project reaches an accomplishment of ninety five (95%) of the total contract amount,
the Procuring Entity may create an inspectorate team to make preliminary inspection and
submit a punch-list to the Contractor in preparation for the final turnover of the project. Said
punch-list will contain, among others, the remaining Works, Work deficiencies for necessary
corrections, and the specific duration/time to fully complete the project considering the
approved remaining contract time. This, however, shall not preclude the claim of the Procuring
Entity for liquidated damages.

45. Suspension of Work

74
 45.1 The Procuring Entity shall have the authority to suspend the work wholly or
partly by written order for such period as may be deemed necessary, due to force
majeure or any fortuitous events or for failure on the part of the Contractor to correct
bad conditions which are unsafe for workers or for the general public, to carry out valid
orders given by the Procuring Entity or to perform any provisions of the contract, or
due to adjustment of plans to suit field conditions as found necessary during
construction. The Contractor shall immediately comply with such order to suspend the
work wholly or partly.

45.2 The Contractor or its duly authorized representative shall have the right to
suspend work operation on any or all projects/activities along the critical path of
activities after fifteen (15) calendar days from date of receipt of written notice from the
Contractor to the district engineer/regional director/consultant or equivalent official, as
the case may be, due to the following:
a) There exist right-of-way problems which prohibit the Contractor from
performing work in accordance with the approved construction schedule.
b) Requisite construction plans which must be owner-furnished are not issued to
the contractor precluding any work called for by such plans.
c) Peace and order conditions make it extremely dangerous, if not possible, to
work. However, this condition must be certified in writing by the Philippine
National Police (PNP) station which has responsibility over the affected area
and confirmed by the Department of Interior and Local Government (DILG)
Regional Director.
d) There is failure on the part of the Procuring Entity to deliver government-
furnished materials and equipment as stipulated in the contract.
e) Delay in the payment of Contractor’s claim for progress billing beyond forty-
five (45) calendar days from the time the Contractor’s claim has been certified
to by the procuring entity’s authorized representative that the documents are
complete unless there are justifiable reasons thereof which shall be
communicated in writing to the Contractor.

45.3 In case of total suspension, or suspension of activities along the critical path,
which is not due to any fault of the Contractor, the elapsed time between the effectivity
of the order suspending operation and the order to resume work shall be allowed the
Contractor by adjusting the contract time accordingly.

46. Payment on Termination

46.1 If the Contract is terminated because of a fundamental breach of Contract by the

Contractor, the Procuring Entity’s Representative shall issue a certificate for the value
of the work done and Materials ordered less advance payments received up to the date
of the issue of the certificate and less the percentage to apply to the value of the work
not completed, as indicated in the SCC. Additional Liquidated Damages shall not apply.
If the total amount due to the Procuring Entity exceeds any payment due to the
Contractor, the difference shall be a debt payable to the Procuring Entity.

46.2 If the Contract is terminated for the Procuring Entity’s convenience or because
of a fundamental breach of Contract by the Procuring Entity, the Procuring Entity’s

75
 Representative shall issue a certificate for the value of the work done, Materials ordered,
the reasonable cost of removal of Equipment, repatriation of the Contractor’s personnel
employed solely on the Works, and the Contractor’s costs of protecting and securing
the Works, and less advance payments received up to the date of the certificate.

46.3 The net balance due shall be paid or repaid within twenty eight (28) days from
the notice of termination.

46.4 If the Contractor has terminated the Contract under GCC Clauses 17 or 18, the
Procuring Entity shall promptly return the Performance Security to the Contractor.

47. Extension of Contract Time

47.1 Should the amount of additional work of any kind or other special circumstances
of any kind whatsoever occur such as to fairly entitle the contractor to an extension of
contract time, the Procuring Entity shall determine the amount of such extension;
provided that the Procuring Entity is not bound to take into account any claim for an
extension of time unless the Contractor has, prior to the expiration of the contract time
and within thirty (30) calendar days after such work has been commenced or after the
circumstances leading to such claim have arisen, delivered to the Procuring Entity
notices in order that it could have investigated them at that time. Failure to provide such
notice shall constitute a waiver by the Contractor of any claim. Upon receipt of full and
detailed particulars, the Procuring Entity shall examine the facts and extent of the delay
and shall extend the contract time completing the contract work when, in the Procuring
Entity’s opinion, the findings of facts justify an extension.

47.2 No extension of contract time shall be granted the Contractor due to (a) ordinary
unfavorable weather conditions and (b) inexcusable failure or negligence of Contractor
to provide the required equipment, supplies or materials.

47.3 Extension of contract time may be granted only when the affected activities fall
within the critical path of the PERT/CPM network.

47.4 No extension of contract time shall be granted when the reason given to support
the request for extension was already considered in the determination of the original
contract time during the conduct of detailed engineering and in the preparation of the
contract documents as agreed upon by the parties before contract perfection.

47.5 Extension of contract time shall be granted for rainy/unworkable days

considered unfavorable for the prosecution of the works at the site, based on the actual
conditions obtained at the site, in excess of the number of rainy/unworkable days pre-
determined by the Procuring Entity in relation to the original contract time during the
conduct of detailed engineering and in the preparation of the contract documents as
agreed upon by the parties before contract perfection, and/or for equivalent period of
delay due to major calamities such as exceptionally destructive typhoons, floods and
earthquakes, and epidemics, and for causes such as non-delivery on time of materials,
working drawings, or written information to be furnished by the Procuring Entity, non-
acquisition of permit to enter private properties or non-execution of deed of sale or

76
 donation within the right-of-way resulting in complete paralyzation of construction
activities, and other meritorious causes as determined by the Procuring Entity’s
Representative and approved by the HoPE. Shortage of construction materials, general
labor strikes, and peace and order problems that disrupt construction operations through
no fault of the Contractor may be considered as additional grounds for extension of
contract time provided they are publicly felt and certified by appropriate government
agencies such as DTI, DOLE, DILG, and DND, among others. The written consent of
bondsmen must be attached to any request of the Contractor for extension of contract
time and submitted to the Procuring Entity for consideration and the validity of the
Performance Security shall be correspondingly extended.

48. Price Adjustment

Except for extraordinary circumstances as determined by NEDA and approved by the
GPPB, no price escalation shall be allowed. Nevertheless, in cases where the cost of
the awarded contract is affected by any applicable new laws, ordinances, regulations,
or other acts of the GoP, promulgated after the date of bid opening, a contract price
adjustment shall be made or appropriate relief shall be applied on a no loss-no gain
basis.

49. Completion
The Contractor shall request the Procuring Entity’s Representative to issue a certificate
of Completion of the Works, and the Procuring Entity’s Representative will do so upon
deciding that the work is completed.

50. Taking Over

The Procuring Entity shall take over the Site and the Works within seven (7) days from
the date the Procuring Entity’s Representative issues a certificate of Completion.

51. Operating and Maintenance Manuals

51.1 If “as built” Drawings and/or operating and maintenance manuals are required,
the Contractor shall supply them by the dates stated in the SCC.

51.2 If the Contractor does not supply the Drawings and/or manuals by the dates
stated in the SCC, or they do not receive the Procuring Entity’s Representative’s
approval, the Procuring Entity’s Representative shall withhold the amount stated in
the SCC from payments due to the Contractor.

below specification requirements has been placed, the Project Manager, at the expense of the
Contractor shall make additional tests. Additional tests may be compression test on cored
cylinder, ASRM C42, and/or load tests as outlined in ACT 318 Sec. 202.

3.4.3 Mixing Concrete

Mixing shall be thoroughly done in a mixer of an approved size and type to insure a uniform
distribution of the materials throughout the mass:

1. Site-Mixed Concrete

All structural concrete shall be machine-mixed for at least 1 ½ minutes after all materials
including water are in the mixing drum. The time elapsed between the introduction of the
mixing of water to the cement and aggregate and placing of the concrete in final position shall
not exceed 45 minutes. Placing of the material in the mixer shall be done in such a way that the
first batch of concrete materials in the mixer shall contain sufficient excess cement, sand and
water to coat the inside of the drum without reducing the cement content of the mix to be
discharged. The tempering of concrete, placing additional cement, aggregate or water during
mixing period shall not be permitted.

105
No hand mixing shall be allowed, except in case of emergency of breakdown during pouring
operations, subject to the approval of the Project Manager.

Concrete shall be placed only after all formworks, materials to be embedded, and preparation
of surface involved in the placing have been inspected and approved by the Project Manager.
The Contractor shall provide equipment and shall employ methods that will minimize
separation of aggregates from the concrete mix.

Water shall be removed from excavation before concrete is deposited. Flow of water shall be
diverted through proper side drains to a pump, or removed by other approved methods to avoid
washing over freshly deposited concrete. Hardened concrete, debris and foreign materials shall
be removed from the interior of forms and from inner surfaces of mixing and conveying
equipment. Reinforcements shall be secured in position, inspected and approved before pouring
concrete. Runaways shall not be provided for wheeled concrete-handling equipment’s, such
equipments shall not be wheeled over reinforcement nor shall runaways be supported by
reinforcements.

Concrete shall be handled from the mixer to the place of final deposits as rapidly as practicable
by methods, which shall prevent segregation or loss of the ingredients. It shall be deposited in
the forms in approximately layers and as nearly as practicable in its final position to avoid re-
handling.

Conveying or handling of concrete by the use of inclined chutes or pipes of more than three (3)
meters shall not be permitted. Dumping of concrete into buggies, buckets or wheelbarrows with
a free fall of more than one (1) meter shall not be permitted. When placing operations would
involve dropping of concrete more than 1 ½ meters, it shall be deposited through a sheet metal
or other approved conveyor. As for practicality, the conveyor shall be kept full of concrete
during placing and their lower ends shall be kept buried in the newly placed concrete. After the
initial set of concrete, the forms shall not be jarred and no strain shall be placed on the ends of
the reinforcing bar, which are being projected.

106
Concrete in columns shall be placed in one continuous operation. Concrete in girders, beams
and slabs in superstructures shall be poured in a monolithic and continuous manner. No
construction joint shall be allowed on any part of the structure without the approval of the
Project Manager.

Consolidate all concrete in accordance with provisions of ACI 309R. Consolidate each layer
of concrete greater than 4 inches in depth with high frequency, interval, mechanical equipment
supplemented by hand spading and tamping. Consolidate concrete slab 4 inches or less in depth
by wood tampers, spading and settling with a heave leveling straight edge. Operate vibrators
with vibratory element submerged in the concrete, with a minimum frequency of not less than
6000 impulses per minute when submerged. Insert and withdraw vibrators approximately 18
inches apart. Penetrate the previously place lift with the vibrator when more than one lift is
required. Place concrete in 180-inch maximum vertical lifts. Limit duration of vibration to time
necessary to produce satisfactory consolidation without causing segregation of aggregates.
Provide adequate number of units and power source at all times. Maintain spare units on hand
to ensure adequacy. If in the opinion of the Project Manager the equipment being used is not
adequate to accomplish proper consolidation, the Project Manager may order delay in further
placement of concrete until such equipment is available for use at the location of placement of
concrete.

3.3.5 Protection and Curing

1. General

Concrete surfaces exposed to conditions causing premature drying shall be protected as soon
as possible with canvas, straw, burlap and or other satisfactory material and kept moist; or if
the surfaces are not covered they shall be kept moist by flushing or sprinkling, as directed by
the Project Manager. All concrete shall be moist cured for a period of not less than seven (7)
consecutive days after placing by an approved method or combination of methods applicable
to local conditions.

2. Moist Cutting

The surface of the concrete shall be kept continuously wet watered for a period of seven (7)
days, by spraying or covering with burlap or other approved material thoroughly saturated with
water and keeping the covering wet by spraying or intermittent hosing. Water for curing shall
be generally lean and free from any element, which might cause objectionable staining or
discoloration of the concrete.

3.4.6 Repairs to the Concrete

All imperfections on concrete surfaces are corrected to produce concrete surfaces that conform
to the requirements of this section. Unless otherwise approved by the Project Manager,
patching with the cement mortar shall repair imperfections on formed surfaces. Cement mortar
for patching shall be the same composition as used in the concrete, except for exposed surfaces;
part of the cement shall be white cement to provide a finish color matching the surrounding
concrete. Honeycomb or otherwise defective areas shall be cut out from solid concrete to a
depth of not less than 25 mm. the edges of the cut shall be perpendicular to the surface of the

107
concrete. The area to be patched, at least 15 mm adjacent thereto shall be saturated with water
before placing the mortar. The mortar shall be mixed approximately one (1) hour before placing
and shall be remixed occasionally during this period with trowel without adding water. A grout
of cement and water, mixed to a consistency of paint, shall then be brushed onto the surface to
which the mortar is to be bonded. The mortar shall be compacted into place and screened
slightly higher than the surrounding surface. Patches on exposed surfaces shall utilize plywood
forms, after the removal of forms, shall not be plastered, unless other wise directed by the
Project Manager. All joint marks on the formwork shall be reworked to a smooth surface to
match adjacent areas and to present a new appearance.

3.4.7 Forms

1) General

lines and dimensions, or to protect the concrete from contamination. Forms shall have sufficient
strength to withstand the pressure resulting from placement and vibration of the concrete, and
shall be maintained rigidly in correct position. Forms shall be sufficiently tight to prevent loss
of mortar from the concrete. Forms for exposed surface shall be lined with form grade plywood.
Bolts and rods used for interval ties shall be so arranged that when the forms are removed, they
shall not be less than two (2) centimeters from the formed surface.

Removal of forms or shoring is subject to approval by the engineer, and under no circumstances
shall bottom form and shoring be removed until after the members have acquired sufficient
strength to support their weight and the load thereon. Forms shall remain in place for a
minimum time as follows:

Columns, sides of beams, shear and bearing

----- 3 days
walls
Beams ----- 14 days

Reshore immediately after stripping beams and girders that support subsequent formwork.

2) Cleaning and Oiling Forms

Before placing concrete, the contact surface of the forms shall be cleaned of incrustations of
mortar, grout or other foreign material. Forms shall be coated with standard form oil that can
effectively prevent sticking and will not stain the concrete surfaces.

3) Removal of Forms

Forms shall be removed in a manner, which shall prevent damage to concrete structures. Forms
shall not be removed without prior approval of the Project Manager. Any repairs of the surface
imperfections shall be performed at once and curing shall be started as soon as the surface is
sufficiently hard to permit it without further damage. The minimum time period for removal of
forms shall govern where it exceeds the minimum specified curing period. Where the formwork
for one element supports the formwork of another element, the greater time period shall apply

108
to both elements. Forms shall not be removed before the expiration of the minimum time
specified below:

TECHNICAL SPECIFICATIONS NEGATIVE PRESSURE ISOLATION ROOM

PURPOSE

This document was developed for “HOSPITAL” to provide a standard basis of design for all
negative isolation rooms. Detailed information including specifications is provided in this
document. Any variation from this standard shall be submitted and reviewed with
“HOSPITAL” Facilities and Engineering Group. This document is intended to be used for
design of all isolation rooms at “HOSPITAL”.

208
GENERAL OVERVIEW

Negative air pressure rooms shall be designed in accordance with the most recent edition of the
Guidelines for Design and Construction of Health Care Facilities, Center for Disease Control
and American Society for Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE)
standards.

These guidelines and standards provide a safe environment for hospital staff treating patients
that require an airborne infection isolation room, as well as protecting the surrounding patients,
general public, and staff outside the airborne infection isolation rooms. In addition to the
minimum criteria, other "architectural" recommendations of an isolation room are needed.
Features that make a room "airtight" are door sweeps, caulking windows, gasketed lighting
fixtures, gasketed ceiling tiles (or solid ceilings), gasketed medical gas, electrical and data
outlets, and sealing "unseen" holes and penetrations behind casework and in the walls above
the ceiling.

These room construction items greatly affect the ability to maintain room static pressure.
Mechanical system features include room pressurization monitors maybe connected to the
Building Automation System (BAS). A connection to the BAS from the isolation room
monitors alerts the engineering staff to problems which may be able to be fixed from the BAS
computer. It also allows the staff to be proactive and identify problems before they cause
alarms. This BAS feature automatically tracks and monitors the room pressures and can
provide printouts for inspectors wishing to check for room pressure compliance. HEPA filters
are required. HEPA filters may not be required if the fans are at the top of the building but this
issue must be reviewed and approved by Facilities Engineering.

All operations and maintenance personnel will need training in the use and maintenance of the
isolation rooms. Site specific programming, alarms, procedures and maintenance schedules
will need to be established along with updating or creating new operational procedures.

The commissioning, training, and start-up will be done during and at the end of the project.

SUMMARY OF NEGATIVE PRESSURE ISOLATION ROOM DESIGN

REQUIREMENTS

The isolation room design requirements are established based on Healthcare Design
Construction Guidelines (2010 Version), CDC Guidelines, and ASHRAE standards.

a. Minimum of 2 outside air changes

b. Minimum of 12 total room air changes (design for 15 total room air changes)

c. Minimum pressure differential of 5.0 pascals (0.02" of water).

d. All air exhausted to the outdoors

e. Visual Monitoring of airflow

f. Self-closing devices on doors

209
g. Exhaust air discharged through HEPA filters if fan is below roof line

h. Exhaust fan on emergency power

j. No positive/negative switch allowed

k. Room is sealed (ceilings, light fixtures, etc.)

l. No gravity type heating devices except radiant panels

SPECIFIC DESIGN ISSUES

“HOSPITAL” requires specific items for the isolation room systems. These items are on the
schematic or in the specifications and are highlighted below for emphasis. Deviation from these
items must be approved by the “HOSPITAL”. The specifications in the appendices are for
reference and shall be incorporated into the project specifications. Other specifications sections

 Annex B
Environmental Codes of Practice (ECOP) Checklist
Checklist 1: COVID-19 Exposure at Health Care Facility

Target: Health Care Workers/Health Care Facility Visitors/Construction Workers

General Infection Prevention and Control

Procedures for entry into health care facilities, such as minimizing visitors and visitor hours,
taking temperature checks and having separate area (including entry area) for patients
presenting with COVID-19 symptoms/respiratory illness, who should be taken to a different
area and given a face mask. All persons visiting hospitals should wash hands before entering
and before leaving.

Minimize contact between patients and other persons in the facility: health care
professionals should be the only persons having contact with patients suspected of having
COVID-19 and this should be restricted to essential personnel only (except in cases of
young children or other persons requiring assistance, then a family member may be present
but they must also be wearing PPE – at least gloves and mask – and adhering to protocols).

Provide alcohol-based hand sanitizer (60-95% alcohol) in common areas

Staff Occupational Health and Safety

Use of and access to Personnel Protection Equipment (PPE) at all times for personnel as
needed (particularly facemask, gowns, gloves, eye protection and potentially face shield),
especially when possibly in contact with someone who may have COVID-19.

Immediate and ongoing training on the procedures to all categories of workers on use of
PPE, personal hygiene, and thorough disinfecting of surfaces on a regular basis.

Place COVID-19 information and hygiene and sanitation reminders in the facility visible to
workers and visitors.

Workers needs to be trained and acquainted with key provisions in Labor Management
Procedure (LMP), in particular Occupational Health and Safety (OHS) aspects.

Sanitation

General cleaning strategies: (i) proceed from cleaner to dirtier areas to avoid spreading dirt
and microorganisms; (ii) proceed from top areas to bottom areas to prevent dirt and
microorganisms from dripping or falling down and contaminating already cleaned areas
(for example clean mattress first, then clean bed legs); (iii) proceed in a methodical,
systematic manner to avoid missing areas (for example, proceed from left to right or
clockwise).

284
 Provide training to workers on proper cleaning procedure as well as appropriate PPE.

Decontamination of construction/working area prior to start of construction activities

activities and associated risks, e.g. falling debris.

Identify trusted community groups for community consultations and which can help to
disseminate messages. Define clear and easy mechanisms to disseminate messages and
materials based on community questions and concerns.

Infection Prevention

Workplaces should be encouraged to post and provide communication materials, in

particular workplaces which may face a higher risk of COVID-19 spread, such as
construction sites and factories. This may include social distancing and isolation measures
in workplaces, opening spaces to allow for natural ventilation, providing hand sanitation
facilities (soap/water or hand sanitizer), etc.

Information on how to protect oneself from COVID-19, the symptoms of COVID-19, where
and how to get tested should be made available to everyone

 Annex C
Labor Management Procedures (LMP) Template
The LMP guide is provided but the Contractor’s Standard Operating Procedures (SOP) may be
submitted if it is compliant with the provisions of the LMP.

Under ESS2 on Labor and Working Conditions, Borrowers are required to develop labor
management procedures (LMP). The purpose of the LMP is to facilitate planning and
implementation of the project. The LMP identifies the main labor requirements and risks
associated with the project, and helps the Borrower to determine the resources necessary to
address project labor issues. The LMP is a living document, which is initiated early in project
preparation, and is reviewed and updated throughout development and implementation of the
project.

B.1 Labor and Working Conditions

Labor Use

The Project will employ about a hundred contracted workers to refurbish existing or construct
new quarantine facilities or isolation rooms in various parts of the Philippines. The Project will
benefit thousands of health workers including medical technicians mostly in major cities in the
country including Baguio City, Cebu, Metro Manila, and Surigao City, including through the
procurement of PPE. Waste management personnel who are expected to be part of the labor force
of health facilities will also benefit from the protection and safety equipment to be provided by
the Project.

Security personnel in hospitals are usually contracted out. Civil servants of the Department of
Health and local government units will be involved as part of the project implementation team.
Community workers will not be employed.

Characteristics of Project Workers

The minimum legal working age in the Philippines is 18 years old. All workers must meet this
requirement. Contracted workers, mainly for civil works, will most likely be male. Health workers
will most likely be female. Health workers will consist of medical professionals directly
employed by the health facilities as organic staff or contracted on a temporary basis. There may
also be some volunteers.

A small number of civil servants from the Department of Health at the national and local levels
and LGUs will be involved in project implementation. Construction workers will be hired in time
for the refurbishment or construction of the isolation facilities.

Health workers are expected to already be working in the hospitals and laboratories. Provision of
laboratory equipment may entail the need to hire additional technicians. Contracted workers are
expected only for the construction of quarantine facilities which will not constitute major civil
works. These will most likely be small, temporary buildings scattered in various areas of the
country with local hospitals in partnership with LGUs in charge of procuring these small
contracts.

290
Health workers will be at the forefront in the fight against Covid 19. As such, they are at the most
risk of infection but with the provision of PPEs, reagents, and technology against the virus, they
are also the main beneficiaries.

Civil servants from the Department of Health and LGUs will be involved in project management
and are expected to abide by social distancing measures and proper hygiene as they carry out their
tasks.

Waste management workers are expected to be part of the labor force of health facilities including
the quarantine facilities to be constructed. Like the health workers, they are highly at risk and will
benefit from the PPEs and other safety measures to be provided by the Project.

Security personnel including the military who will be involved in the Project are expected to
receive the appropriate PPEs from the project. They will abide by a Code of Conduct (CoC) and
DoH will ensure that they are informed about the CoC and receive appropriate training, as needed.

Migrant workers are not expected to be involved. Likewise, community workers are not expected
to be involved. No risks concerning child labor and serious safety issues are identified or expected
concerning primary supply workers as most of the Project’s supplies will be medical equipment
and PPE with a high level of standards and quality control.

B.2 Assessment of Potential Labor Risks

Health workers, waste management and security personnel will be more at risk of infection
without the provision of PPE and the use of disinfectants that will be provided by the project.
With physical mobility being restricted and given the nature of construction activities, labor influx
is not expected. However, the movement of laborers from the worksite to the community may
increase the risk of infection in both areas.

COVID-19 specific risks relate to the activities being carried out by the workers, in the context in
which the project is being conducted. Potential risks could include workers mobilized from
adjoining provinces or regions, or local workers returning from abroad, become vectors for
transmission of COVID-19 to other workers in construction project sites and nearby communities.

These risks may be minimized and addressed through:

● conducting pre-employment health checks

● controlling entry and exit from site/workplace
● reviewing accommodation arrangements, to see if they are adequate and designed
to reduce contact with the community
● reviewing contract durations, to reduce the frequency of workers entering/exiting
the site
● rearranging work tasks or reducing numbers on the worksite to allow
social/physical distancing, or rotating workers through a 24-hour schedule
● providing appropriate forms of personal protective equipment (PPE)
● putting in place alternatives to direct contact, like telemedicine appointments and
livestream of instructions.
Another example of potential risk is where the project activity is the treatment by health care
workers of COVID-19 patients. In this case the risks could include pathogen exposure, infection
291
and associated illness, death, illegal and untenable overtime, psychological distress, fatigue,
occupational burnout, stigma and passing on infections to family and community.

B.3 Labor Legislation

Presidential Decree No. 44, as amended by RA 6715, known as the “Labor Code of the
Philippines”, governs all employment practices and relations in the country. Provisions of the
code are aligned with international good practice on decent work and shall be strictly
implemented. These provisions include:

Wage and Welfare

1. Employees shall receive their wages by means of legal tender, at least once every two
weeks or twice a month at intervals not exceeding sixteen (16) days.

working hours, he/she shall be given overtime pay.
2. It is the right of every employee for a rest period not less than twenty-four (24) consecutive
hours after every six (6) consecutive normal workdays.
3. Compensation shall be given for work performed during holidays and Sundays.
Equal Rights

1. Workers shall have the right to self-organization and to form, join, or assist labor
organizations of their own choosing for purposes of collective bargaining.
2. Minimum employable age is 18 years old. Persons of age 15 to 18 can be employed given
that they work in non-hazardous environment.
3. Gender discrimination in employment and labor relations shall be prohibited. Male and
female employees are entitled to equal compensation for work of equal value and access to
promotion and training opportunities.
Occupational Health and Safety

According to Chapter III of Republic Act No. 11058 (the OSH Law), the following are the duties
of every Procuring Entity, contractor or subcontractor, and any person who manages, controls or
supervises the work:

292
1. Equip a place of employment for workers free from hazardous conditions that are causing
or are likely to cause death, illness or physical harm to the workers where physical distancing can
be observed. Sanitation and hygiene facilities should also be present and well- disinfected

industrial dangerous and poisonous factors

293
The Occupational Safety and Health Standards, in compliance with Article 162 of the Labor
Code of the Philippines, was formulated to protect every working man against the dangers of
injury, sickness or death through safe and healthful working conditions. For this project, chapters
discussing standards for personal protective equipment and devices, construction safety, and
hazardous materials are necessary and should be complied.

DPWH Department Order 56 series of 2005: Guidelines for the Implementation of Department
of Labor and Employment (DOLE) No.13 series of 1998, Guidelines in the Governing
Occupational Safety and Health in the Construction Industry, it is expected that the contractors
should follow the said guidelines to eliminate or reduce occupational safety and health hazards
in all work places, and institute new, and update existing programs to ensure safe and healthful
working conditions in all places of employment.

The following international conventions, and directives may also support measures for
addressing health and safety issues relevant to COVID-19:

● ILO Occupational Safety and Health Convention, 1981 (No. 155)

● ILO Occupational Health Services Convention, 1985 (No. 161)
● ILO Safety and Health in Construction Convention, 1988 (No. 167)
● WHO International Health Regulations, 2005
● WHO Emergency Response Framework, 2017
B.4 Grievance Redress Mechanism

Management of DOH personnel is governed by the Civil Service Commission which requires
the establishment of a Grievance Redress Committee in- charge of preventing and addressing
grievances as stipulated in the following provisions:

● The Grievance Committee shall develop and implement pro-active measures or activities
to prevent grievance such as employee assembly which shall be conducted at least once every
quarter, “talakayan” counseling and other HRD interventions;
● Conduct continuing information drive on Grievance machinery among officials and
employees in collaboration with the Personnel Administration Division;
● Conduct dialogue between and among the parties involved;
● Conduct investigation and hearing within ten (10) days from receipt of the grievance and
render decision within five (5) working days after the investigation. Provided, however where
the object of the grievance is the grievance committee, the aggrieved party may submit the
grievance to top management;
● Direct the documentation of the grievance management process including the preparation
and signing of written agreements reached by the parties involved:
● Issue Certification on the Final Action on the Grievance (CFAG) which shall contain,
among other things, the information, history and final action taken by the agency on the
grievance, and;
● Submit a quarterly report of its accomplishments and status of unresolved grievance to

Contractors

294
Contractors are expected to hire much of their laborers upon assuming the civil works contract.
At the time of recruitment, workers will be informed of the grievance mechanism and the
measures put in place to protect them against any reprisal for its use. The grievance mechanism
shall be made easily accessible to all project workers. Regular meetings with the project workers
to discuss any work-related issues and concerns will be conducted. Every grievance raised by a
worker will be documented with the actions undertaken by the office to address such grievance.
The aggrieved worker may raise any issue anonymously through a letter which shall be submitted
to his/her immediate supervisor’s office. All non-anonymous grievances relative to adequate
working conditions, standard occupational safety and health and other concerns from the workers
shall be addressed following the procedures outlined below:

● The grievance shall be filed by the workers to the Contractor who shall follow the DOLE
procedures in handling the complaints. The Contractor shall act within 15 days upon receipt
thereof;
● If no understanding or amicable solution can be reached, or if the complainant does not
receive a response from the Contractor within 15 days of registry of the complaint, he/she can
appeal to the project grievance focal person within DOH, which should act on the
complaint/grievance within 15 days from the day of its filing. If the PIU does not see itself fit to
address the complaint it will immediately bring the matter to the concerned DOLE office.
● If the complainant is not satisfied with the resolution offered by the PIU, he/she can appeal
to the concerned DOLE office, which should act on the complaint/grievance within 15 days from
the day of its filing.
B.5 Contractor Management

Responsibilities of Bureau of International Health Cooperation (BIHC)

1. The BIHC will request details in writing before a contract is signed from the Contractor
of the measures being taken to address labor and working conditions risks. The construction
contract should include health and safety requirements, and these can be used as the basis for
identification of, and requirements to implement, COVID-19 specific measures. The measures
may be presented as a contingency plan, as an extension of the existing project emergency and
preparedness plan or as standalone procedures. The measures may be reflected in revisions to the
project’s health and safety manual.

2. The BIHC should require the Contractor to convene regular meetings with the project
health and safety specialists and medical staff (and where appropriate the local health authorities),
and to take their advice in designing and implementing the agreed measures.

3. The contractor shall assign a senior staff as a focal point to deal with COVID-19 issues
during construction. This can be a work supervisor or a health and safety specialist. This person
can be responsible for coordinating preparation of the site and making sure that the measures
taken are communicated to the workers, those entering the site and the local community. It is also
advisable to designate at least one back-up person; in case the focal point becomes ill; that person
should be aware of the arrangements that are in place.

4. The BIHC may provide support in identifying appropriate mitigation measures,

particularly where these will involve interface with local services, in particular health and
emergency services. In many cases, the BIHC can play a valuable role in connecting the
Contractor with local Government agencies, and helping coordinate a strategic response, which
takes into account the availability of resources.
295
5. Workers should be encouraged to use the existing project grievance mechanism to report
concerns relating to COVID-19, preparations being made by the project to address COVID-19
related issues, how procedures are being implemented, and concerns about the health of their co-
workers and other staff.

6. The BIHC, in coordination with local LGU and health facility, shall issue construction
quarantine pass to the individual qualified personnel of the contractors, subcontractors, and
suppliers, clearly stating the identification, designation, nature of work, validity and destination.
It is understood that the pass shall cover transit of personnel from (a) General Community

national, WHO).

298
15. Consider whether existing project medical services are adequate, taking into account
existing infrastructure (size of clinic/medical post, number of beds, isolation facilities), medical
staff, equipment and supplies, procedures and training. Where these are not adequate, allocate in
the project cost the upgrading of services, including:

● Training medical staff, which should include current WHO advice on COVID-19 and
recommendations on the specifics of COVID-19. Where COVID-19 infection is suspected,
medical providers on site should follow WHO interim guidance on infection prevention and
control during health care when novel coronavirus (nCoV) infection is suspected.
● Assessing the current stock of equipment, supplies and medicines on site, and obtaining
additional stock, where required and possible. This could include medical PPE, such as gowns,
aprons, medical masks, gloves, and eye protection. Refer to WHO guidance as to what is advised.
● If PPE items are unavailable due to world-wide shortages, medical staff on the project
should agree on alternatives and try to procure them. Alternatives that may commonly be found
on constructions sites include dust masks, construction gloves and eye goggles. While these items
are not recommended, they should be used as a last resort if no medical PPE is available.
● Ventilators will not normally be available on work sites, and in any event, intubation
should only be conducted by experienced medical staff. If a worker is extremely ill and unable to
breathe properly on his or her own, they should be referred immediately to the local hospital.
● Review existing methods for dealing with medical waste, including systems for storage
and disposal.

16. Given the limited scope of project medical services, the project may need to refer sick
workers to local medical services. Preparation for this includes:

● Obtaining information as to the resources and capacity of local medical services (e.g.
number of beds, availability of trained staff and essential supplies).
● Conducting preliminary discussions with specific medical facilities, to agree what should
be done in the event of ill workers needing to be referred.
● Considering ways in which the project may be able to support local medical services in
preparing for members of the community becoming ill, recognizing that the elderly or those with
pre-existing medical conditions require additional support to access appropriate treatment if they
become ill.
● Clarifying the way in which an ill worker will be transported to the medical facility, and
checking availability of such transportation.
● Establishing an agreed protocol for communications with local emergency/medical
services.
● Agreeing with the local medical services/specific medical facilities the scope of services
to be provided, the procedure for in-take of patients and (where relevant) any costs or payments
that may be involved.

B.6 Use of security personnel

Health facilities supported by the project is expected to use some security personnel. Normally a
security agency is contracted on a long-term basis by health care facilities to ensure safety of
employees and the facility, including the equipment and supplies. In relation to security of the
equipment during delivery, DOH’s freight service provider ensures that all equipment is delivered
intact and safe onsite. DOH reports that security has not been an issue in the delivery of equipment
in different areas nationwide.

299
The Project is not expected to use government security personnel in construction of facilities
financed by the Project. However, as COVID-19 may develop in unpredictable ways and due to
potential concerns among the public, the use of additional government security personnel from
the local or national police, or in some instances possibly the military, may be directed to
implement measures to ensure peace and order in affected areas, including at quarantine, isolation,
decontamination and other health facilities.

The potential scope of such security measures, and potential risks surrounding them, will be
assessed and monitored during implementation and this LMP may be revised accordingly to
manage environmental and social risks concerning project activities. The World Bank’s ESS4 on
Community Health and Safety encourages disclosure of government security arrangements and
that clients ensure that government personnel act in a manner consistent with the provisions of
the standard.

In case project activities are supported by private or government security personnel, it will be
ensured that the security personnel follow a strict code of conduct and avoid any escalation
consistent with the ESF and IFC guidance on the use of security personnel (IFC Good Practice
Handbook on the Use of Security Forces: Assessing and Managing Risks and Impacts). In these
cases, DOH (through BIHC) will assess risks posed by these security arrangements to project
workers and the local community. Security personnel will provide security services in a manner
consistent with the applicable laws and code of practices and will be consistent with the relevant
requirement of the World Bank’s ESS4. DOH will ensure that the workers and local community
are informed about the arrangements and the project’s GRM. DOH will review any allegations of
unlawful or abusive acts of security personnel, take action (or urge appropriate parties to take
action) to prevent recurrence and, where necessary, report unlawful abusive acts to the relevant
authorities.

 Annex D
Project Grievance Redress Mechanism (GRM)
The main objective of a Grievance Redress Mechanism (GRM) is to assist to resolve complaints
and grievances in a timely, effective and efficient manner that satisfies all parties involved.
Specifically, it provides a transparent and credible process for fair, effective and lasting outcomes.
It also builds trust and cooperation as an integral component of broader community consultation
that facilitates corrective actions. Specifically, the GRM:

▪ Provides affected people with avenues for making a complaint or resolving any dispute
that may arise during the course of the implementation of the Project;
▪ Ensures that appropriate and mutually acceptable redress actions are identified and
implemented to the satisfaction of complainants; and
▪ Avoids the need to resort to judicial proceedings.

The Contractor will have to develop a Contractor’s Personnel GRM based on the Project GRM
for its personnel to be submitted to the DOH. The Contractor’s Personnel GRM is the procedure
of the Contractor to resolve the complaints of its personnel, which may be already a part of its
SOP. If it is already present, the Contractor should submit it as a separate document entitled
‘Contractor's Personnel Grievance Redress Mechanism (GRM).’ If the GRM/ complaint
resolution is currently not part of the SOP, the Contractor may pattern in after the Project GRM
provided below.

The Project GRM will include the following steps:

1. Submission of project implementation related grievances through an official/formal

document to:
a. the Head of the Health Care Facility if the grievance occurred in a health care facility
b. the Local Health Unit/ LGU, i.e. Provincial Health Office/ City Health Office/ Municipal
Health Office, as appropriate, if the grievance occurred in the community setting
2. Recording of grievance by the health care facility or Provincial/City/Municipal Health
Office (P/C/MHO; LGU), as appropriate, within 24 hours.
3. Providing initial response to the concerned stakeholder/s (complainant) within 3 days after
receipt of grievance.
4. Investigation of grievance by the concerned health care facility or PHO/CHO/MHO
(LGU) within 7 days after providing initial response to the complainant.
5. Communication of response to the complainant by the health care facility or
PHO/CHO/MHO (LGU), as appropriate.
6. If the complainant believes that the grievance has not been resolved and closed at the local
level, the complainant will submit an official communication letter to the concerned Center for
Health Development (CHD; DOH Regional Office) together with the documentation of the health

311
care facility or PHO/CHO/MHO (LGU) response and relevant attachments, within 3 days after
receiving the previous grievance response.
7. Investigation of grievance by the DOH CHD concerned within 7 days after receiving
official communication from complainant.
8. Communication of response to the complainant by the DOH CHD.
9. If the complainant believes that the grievance has not been resolved and closed at the
regional level, the complainant may re-appeal to the DOH Central Office- Office of the Secretary,
through submission of an official communication letter to the DOH Central Office- Office of the
Secretary, together with all the previous official communications and relevant documents.
10. Endorsement of the unresolved grievance by the DOH Central Office- Office of the
Secretary to the concerned DOH Centers for Health Development or Bureaus, for re-investigation
and addressing of the grievance, within 7 days after receiving official communication from
complainant.
11. Communication of response to the complainant by the DOH CHD or Bureaus concerned,
informing also the DOH Central Office- Office of the Secretary.

Monitoring Form Template for the Project’s Grievance Redress Mechanism (GRM)

The template below will be used for the monthly and yearly monitoring of the Project’s GRM:

Month/Year:

If the re-appeal for the grievance was not submitted within the specified timeframe in the GRM
steps above, it will still be reconsidered, and the grievance will be re-opened. However, if the
same grievance has been previously reported in the ISR indicator as resolved, the previous report
will not be changed and it will be noted in the monitoring that the grievance was re-opened upon
re-appeal submission of proponent after deadline. The ‘re-opened grievance upon re-appeal
