Conditions: Part 1: General

Clause 1: Interpretation, definitions, etc.

1.1 All clause references relate to the Conditions of Contract unless

specifically stated otherwise.
1.2 The Contract is to be read as a whole. Thus, any term is subject to
qualification by other terms, usually related and cross-referenced,
unless specified as to be read in isolation.
This is a general principle of law.
1.3 Definitions essential to the interpretation of the Contract (most are
self-explanatory).
The definitions listed refer to the Contract as a whole; those
given in individual clauses are in the context of that clause only
(e.g. Variation – Clause 13.1).
Following the ruling by the Court of Appeal in Jarvis John Ltd v.
Rockdale Housing Association (1986) the meaning of ‘the Contrac-
tor’ in JCT 80 (and similar contracts) includes the servants and
agents of the Contractor (i.e. those through whom the organisa-
tion operates). It is probable that the definition does not include
sub-contractors.
1.4 Not used.
1.5 Despite the roles and responsibilities of the Architect, and any CoW,
the Contractor is wholly responsible for the execution of the Works
in accordance with the Contract – Clause 2.1. Only the Final
Certificate, as noted in Clause 30.9.1.1, provides conclusive
evidence of the Works’ compliance with the requirements of the
Contract.
1.6 If the Employer appoints or replaces the Planning Supervisor or
Principal Contractor he must inform the Contractor in writing.
1.7 If no provision is made for the giving or service of notices or docu-
ments they shall be served by an effective means to an agreed
address. If no address is agreed then the delivery to the last known
principal or registered business address will be treated as effective
giving or serving.

11
12 Clause 1

1.8 Where the contract requires an act to be done in a specified

number of days the period begins immediately; public holidays are
excluded.
1.9 The Employer must give written notice to the Contractor that an
individual will exercise all the functions ascribed to the Employer’s
Representative. A footnote says that neither the Architect nor the
Quantity Surveyor should be appointed to the role of Employer’s
Representative.
1.10 The law of the contract shall be English law irrespective of the
nationality, residence or domicile of the Parties or the location of
the Works.
1.11 Where the Appendix so states, the Parties have agreed to Electronic
Data Interchange.
Clause 2: Contractor’s obligations

2.1 Primary obligation for the Contractor to execute and complete the
Works in accordance with the Contract Documents.
English Industrial Estates Corporation v. Kier Construction (1991):
(Contract was ICE5.) Following Yorkshire Water Authority v. McAlpine
(1986), the arbitrator held that although a method statement,
normally, was not a contract document, because the method
statement was attached to the tender (which was a contract
document), such attaching caused the method statement to
become a contract document.
If the quality is to be the subject of the opinion of the Architect,
if must be his reasonable satisfaction (something the BQ should
define).
Thus, the Architect cannot demand better quality than is stated
in the Contract Documents, as amended by AIs, regarding quality,
etc.
By its nature, this condition excludes any design responsibility
on the part of the Contractor – he undertakes to complete the
Works in accordance with the supplied design; he does not under-
take that the building will be suitable for its intended purpose.
Neither does the Contractor undertake that the building will not
fail, unless due to standards of workmanship, etc., not in accor-
dance with the Contract. He does not contract to produce a result.
See Cable v. Hutcherson Bros. Pty. (1969) (Australian).
However, the Courts now regard Contractors as experts in con-
struction and so any design matter that the Contractor considers
dubious should be queried by him, in writing, to the Architect,
requesting his instruction and indicating the possible construction
problems and/or possible subsequent failure.
Following Duncan v. Blundell (1820), Equitable Debenture Assets
Corporation Ltd v. Wm. Moss and others (1984) and Victoria Univer-
sity of Manchester v. Hugh Wilson & Lewis Womersley and others
(1984), an implied term exists for the Contractor to warn the Archi-
tect of design defects known to the Contractor and of such defects
the Contractor believes to exist. The belief requires more than mere
doubt as to the correctness of the design but less than actual
knowledge of errors.
Such action should relieve the Contractor of any liability for sub-
sequent building failure due to inadequate or inappropriate design.
‘To complete the Works’ refers to practical completion, the point
at which, inter alia, the defects liability period (DLP) commences.

13
14 Clause 2

Certain contractual requirements cease at this point also e.g. fire

insurance and liquidated damages liability.
‘The Architect (or Employer) may dictate the working hours,
order of work execution and postponement of work but not the
method of executing the work.
2.2 .1 Contract Bills may not override or modify provisions of the
Articles, Conditions or Appendix but may affect them, e.g. by
noting obligations or restrictions imposed by the Employer.
See Gleeson M.J. Ltd v. London Borough of Hillingdon
(1979).
John Mowlem & Co. Ltd v. British Insulated Callenders Pension
Trust Ltd (1977): (BQ attempted to constrain a performance
specification for watertight concrete; consulting engineers
used for structural design.) There must be a very clear con-
tractual condition to render a contractor liable for a design
fault. Design is a matter which a structural engineer is quali-
fied to execute, which the engineer is paid to undertake and
over which the Contractor has no control.
.2.1 Contract bills – to have been prepared in accordance with
SMM7. Any departure from SMM7 must be specified in
respect of each item or items – usually in the Preambles.
.2 Any error in the BQ or any departure from SMM7 not spe-
cified – not to vitiate the Contract but to be corrected and
the correction treated as a Variation in accordance with
Clause 13.2.
Bryant & Son Ltd v. Birmingham Hospital Saturday Fund
(1938): If the Bills do not describe the work appropriately, costs
of changes necessary are additional to the Contract Sum.
Note: If the error or departure were sufficiently great so
as to change the entire basis or nature of the Contract, it is
probable that it would vitiate the Contract.
See Pepper v. Burland (1792).
The errors are those concerning BQ preparation by the
PQS, not pricing errors by the Contractor.
2.3 Discrepancies in or divergencies between documents.
If the Contractor finds a discrepancy between any of the
specified documents – drawing, BQ, AIs (except Variations),
drawings or documents issued under Clause 5, and the Numbered
Documents (annexed to Agreement NSC/A) – Contractor to
give the Architect written notice specifying the discrepancy
and the Architect shall issue instructions to solve the
problem.
Clause 2 15

‘If ’ indicates that the Contractor is not bound to find any

discrepancies but specifies what the Contractor must do should he
make such a discovery.
Again, pricing errors by the Contractor are not covered nor is
his misinterpretation of the design, unless the design is ambigu-
ous, in which case he may claim.
However, the Contractor is considered to be an expert in con-
struction and so the Courts will require him to execute the ap-
propriate duty of care in such things as cross-checking Contracts
Documents and drawings.
Thus this situation is by no means crystal-clear; the Contractor
should check and only in extreme cases place reliance on this
Clause to avoid any liability.
However, in L.B. Merton v. Stanley Hugh Leach Ltd (1985), the
judge accepted that the Contractor was not obliged to check draw-
ings to seek discrepancies or divergencies so as to impose a duty
on the Architect to provide further information.
Normally the Contract provisions will prevail over other Con-
tract Documents, e.g. BQ.
See Gold v. Patman & Fotherington (1958).
Supply of Goods and Services Act (1982): implied term that a
supplier, acting in the course of a business, will carry out the service
with reasonable skill and care.
2.4 The two parts of this Clause concern Performance Specified Work
(as detailed in Part 5 of the Contract) for which the Contractor
must provide a statement on how the performance specification
will be met; hence, the Contractor must design the work con-
cerned to comply with the specification (fitness for purpose to that
extent).
.1 If the Contractor finds a discrepancy or divergence between
his Statement and AI issued by the Architect after receipt of
the Contractor’s Statement – Contractor to give the Architect
written notice specifying the discrepancy/divergence, Archi-
tect to issue an instruction on the matter.
.2 If the Contractor or the Architect finds a discrepancy in the
Contractor’s Statement – Contractor to correct the Statement
to remove the discrepancy at no cost to the Employer and
inform the Architect in writing of the correction.
Clause 3: Contract Sum – additions
or deductions – adjustment –
Interim Certificates

Where the Contract provides for the Contract Sum to be adjusted, as soon
as any such adjustment amount has been determined, even if partial (or
even, presumably, ‘on account’) it should be included in the computa-
tion of the following Interim Certificates.
This is a distinct aid to the Contractor’s cash flow, the ‘life-blood’ of
the industry, by requiring even estimate, partial or ‘on account’ Valuations
of extras to be included in the following (Valuation and) certification for
payment.

16
Clause 4: Architect’s instructions

4.1.1 Contractor to forthwith comply with all AIs which the Architect
expressly empowered by the Conditions to issue.
The exceptions are:
.1 where such an instruction is one requiring a Variation, the
Contractor need not comply if he has made reasonable objec-
tion in writing to the Architect
.2 where such an instruction is one requiring a Variation, the
Contractor need not comply if a 13A Quotation has been
issued
(a) until the Architect issues an acceptance of the 13A
Quotation
(b) until an instruction in respect of the Variation has been
issued under Clause 13A.4.1.

4.1.2

4.2 Contractor receives what purports to be an AI from the Architect.

Contractor may request Architect to specify the authority (which
Clause) for the instruction, in writing.
Architect complies with request, forthwith.
Contractor complies with the instruction – deemed, in all cases,
to be a valid AI.
4.3.1 All instructions issued by the Architect – to be in writing
.2 Non-written (verbal) instruction – of no immediate effect. Con-
tractor to confirm the instruction to the Architect within 7 days.
Architect has 7 days from receipt of confirmation to dissent in
writing, if not becomes valid AI.

17
18 Clause 4

.1 Architect may confirm an oral instruction within 7 days – no

need for Contractor to confirm – is valid AI from the date of
the Architect’s written confirmation.
.2 No confirmation of an oral instruction but the Contractor
complies – Architect may confirm in writing prior to the issue
of the Final Certificate – deemed to be a valid AI on the date
when given orally.
This course of action imposes considerable risk of loss upon
the Contractor and much reliance on the Architect’s memory!
Clause 5: Contract documents – other
documents – issue of certificates

5.1 Contract Drawings and Bills to remain in the custody of the Archi-
tect or QS and be available at all reasonable times (usually normal
working hours) for the inspection of the Contractor and Employer.
5.2 Immediately the Contract is executed, the Architect to provide free
to the Contractor:
.1 1 copy of the Contract Documents certified on behalf of the
Employer.
.2 2 further copies of the Contract Drawings.
.3 2 copies of the unpriced BQ.
5.3.1 As soon as possible after the execution of the Contract:
.1 Architect to provide free to the Contractor, 2 copies of all
descriptive schedules, etc., necessary for use in carrying out
the Works.
.2 Contractor to provide free to the Architect, 2 copies of the
master programme. Amendments made within 14 days of
Extension of Time award (clause 25.3.1), i.e. to be kept
updated in accordance with Architect’s Extension or Time
awards. (Useful to show when information will be required.)
Or from the date of a confirmed acceptance of a 13A
Quotation.
Note: A network will show the effects of delays far more
clearly than a bar chart.
The following points should also be noted:
(a) There is no definitive statement indicating the form of the
programme or what it is to show. The type of programme and
information shown is, thus, at the option of the Contractor (in the
absence of any agreement denoting specific type of programme
and information required). Thus a simple bar chart, a network or
any other type of chart will be compliant. Normally, it is suggested
that the programme should be of a type in common usage, clearly
denoting key dates and work sequences, etc. BQ may note form
of programme required.
(b) If a Contractor disagrees with an extension or other Com-
pletion Date modification by the Architect, in order to further his
claim, it would be perhaps prudent not to amend the programme

19
20 Clause 5

to comply with the Architect’s award but to revise the programme

to comply with the Contractor’s own estimate of the appropriate
Extension of Time and to indicate by this means the procedure for
completion by that date.
Indeed, it should be borne in mind that there is no provision in
the Contract for the Contractor to amend the programme to take
account of the Architect’s reduction of an Extension of Time (due
to work being omitted).
.2 Nothing in the supplementary documents (schedules, master pro-
gramme, etc.) may impose any obligation beyond those imposed
by the Contract Documents.
5.4 Architect to provide free to the Contractor, 2 copies of all neces-
sary drawings and details, supplementary to the Contract Draw-
ings, to enable the Contractor to execute the Works.
5.5 Contractor to keep on site and available for the Architect (or
representative) at all reasonable times:
(a) 1 copy of Contract Drawings
(b) 1 copy of unpriced BQ
(c) 1 copy of Schedules, etc.
(d) 1 copy of master programme (if applicable)
(e) 1 copy of drawings and details
Reasonable times likely to be construed as site working hours (or
normal working hours, if longer).
5.6 Upon final payment, the Contractor to return to the Architect all
drawings, schedules, etc., which bear Architect’s name, if
requested to do so.
5.7 Limits to use of documents.
Documents to be used for the purposes of the Contract only
and for no other projects.
Employer, Architect and QS may use the BQ rates or prices only
for the purposes of the Contract – also may not divulge them
except for the purposes of the Contract.
5.8 Normally, all Certificates must be issued to the Employer by the
Architect who must immediately send a duplicate copy to the
Contractor.
Exception:
35.15.1 failure of NS/C to complete by appropriate date.
Following L. B. Merton v. Stanley Hugh Leach Ltd (1985) it should
be noted that the following terms are implied:
Clause 5 21

(a) the Employer will not hinder or prevent the Contractor

carrying out his obligations under the Contract or from
executing the Works in an orderly and regular way,
(b) the Employer undertakes that the Architect will do all required
to enable the Contractor to carry out the work,
(c) where the Architect is required to supply the Contractor with
drawings, etc. during the course of the work, those drawings,
etc. must be accurate.
5.9 Contractor to provide free to the Employer, drawings and other
information describing Performance Specified Work as built and
maintenance as specified in the BQ or AI(s) for expenditure of the
appropriate provisional sum.
Clause 6: Statutory obligations, notices,
fees and charges

6.1 .1 Overriding obligation to comply with any and all Statu-

tory Requirements, including the regulations of statutory
undertakers.
.2 If the Contractor finds any divergence between the Statutory
Requirements and the Contract Documents, Drawings, etc.,
or AIs he must immediately inform the Architect, in writing,
specifying the divergence.
Note: the role of ‘if’, not ‘when’, and the implications as
discussed previously.
.3 If the Contractor gives notice or by some other means the
Architect discovers such divergence, he has 7 days from
receipt of any notice in which to issue instructions about the
matter. If such instructions require the Works to be varied,
this constitutes a valid Variation (Clause 13.2).
.4 .1, .2, .3, Emergency compliance with Statutory Require-
ments prior to instructions being received:
Contractor to supply necessary materials and to execute
necessary emergency work.
Contractor to inform the Architect immediately of the
situation and the steps being taken.
Such materials and work are then deemed to be pursuant
to an AI, provided that the necessity for the emergency work
was due to a divergence as described – valuation will be made
accordingly (Clause 13.2).
.5 Provided that the Contractor has complied with the require-
ments regarding divergence, he is not liable where the Works
do not comply with any Statutory Requirements, provided
that they do comply with the Contract Documents, includ-
ing Drawings.
Note: This liability avoidance is contractual only, i.e.
expressly restricted to liability to the Employer.
.6 If the Contractor or Architect finds a discrepancy between the
Statutory Requirements and any Contractor’s Statement:
immediately give the other written notice specifying the
discrepancy,

22
Clause 6 23

Contractor to inform the Architect of the amendment

proposed to remove the divergence, and Architect to issue
appropriate instructions.
Contractor’s compliance with AIs issued under this Clause
to be at no cost to the Employer (except as provided in Clause
6.1.7).
.7 Any changes in Statutory Requirements after the Base Date
which necessitate a change to Performance Specified Work
to be treated as an AI requiring a Variation (Clause 13.2) and
valued accordingly.
No Contractor may construct a building which does not
comply with the applicable Statutory Requirements.
6.2 Fees and charges – Contractor to pay and indemnify the Employer
in respect of all statutory fees and charges.
Such fees and charges, including all taxes except VAT, are added
to the Contract Sum unless they:
.1 arise due to a statutory undertaker being a NSup or NS/C; or
.2 are priced in the Contract Bills; or
.3 are a provisional sum in the Contract Bills.
6.3 The contractual provisions regarding assignment and sub-letting
(Clause 19) and NS/Cs (Clause 35) do not apply to statutory under-
takers carrying out their statutory obligations. For this purpose they
are not Sub-Contractors within the meaning of the Contract.
Clause 6A: Provisions for use where the
Appendix states that all the CDM
Regulations apply

6A.1 The Employer shall ensure:

that the Planning Supervisor carries out all the duties of a planning
supervisor under the CDM Regulations
where the Contractor is not the Principal Contractor, that the Prin-
cipal Contractor carries out all the duties of a principal contractor
under the CDM Regulations.
6A.2 Where the Contractor is a Principal Contractor he must comply
with all the duties set out in the CDM Regulations, in particular the
Health and Safety Plan.
6A.3 Where the Employer appoints another Principal Contractor the
Contractor shall comply, at no extra cost, with all reasonable
requests and no extension of time shall be given.
6A.4 The Contractor shall provide, and ensure that any sub-contractor
provides, any information required for the health and safety file
required by the CDM Regulations.

24
Clause 7: Levels and setting out of
the Works

The Architect is obliged to determine and provide the Contractor with all
requisite levels and dimensions for the execution of the Works.
The Contractor is responsible for correcting at his own cost any setting
out errors for which he is responsible, i.e. his inaccuracies in setting out.
Provided that the Employer has consented, the Architect may issue an
instruction permitting an inaccurately set out building to be completed
with an appropriate price reduction by the Contractor.
Trespass: If setting out causes a trespass on adjoining property, the injured
party has an action:
(a) against the Contractor if the trespass is caused by setting out
error(s) on his part,
(b) against the Employer (who may be able to recover from the Archi-
tect) if the trespass is caused by inaccurate drawings or other infor-
mation supplied by the Architect.
See Kirkby v. Chessum & Sons Ltd (1914).
Note: The Contractor may be required to insure against the risks
involved:
(a) Clause 20.2
(b) Clause 21.2.1.

25
Clause 8: Work, materials and goods

8.1 Bills to describe all materials, goods and workmanship, thus the
BQ acts as the specification document. For Performance Specified
Work, the materials and goods must accord with the Contractor’s
Statement.
‘So far as procurable’ modifies this overall requirement – may be
best to give alternatives, if applicable – e.g. paint manufacturer’s list,
in the Preambles. If this is not done, the phrase may be deemed to
mean the nearest substitute to the specified item, if unavailable.
Materials and goods must be to the Architect’s reasonable
satisfaction, in accordance with Clause 2.1.
This clause has led to the wide use of the term ‘or equal and
approved’ – this means the Architect may approve other goods,
not must.
See Leedsford Ltd v. Bradford Corporation (1956).
Where described therein, workmanship must be to the standards
in the BQ or Contractor’s Statement; otherwise, workmanship must
be to a standard appropriate for the Works. Workmanship must be
to the Architect’s reasonable satisfaction, in accordance with Clause
2.1.
.3 All work shall be carried out in a proper and workmanlike
manner and in accordance with the Health and Safety
Plan. (Following: Court of Appeal – Greater Nottingham Co-
Operative Society Ltd v Cementation Piling and Foundations Ltd
(1988).)
.4 Contractor must have the Architect’s written consent (not to
be unreasonably withheld or delayed) to substitute any mate-
rials or goods for those described in any Contractor’s State-
ment. The Contractor retains all responsibilities for any
properly substituted materials or goods.
8.2.1 Architect may require the Contractor to provide vouchers to prove
that the goods and materials comply with the specified require-
ments as Clause 8.1.
.2 If the Architect is not satisfied with materials, goods or workman-
ship included in work which has been executed and which is
required to be to his reasonable satisfaction (in accordance with
Clause 2.1), the Architect must express such dissatisfaction within
a reasonable time from the execution of the (alleged) unsatisfac-
tory work.

26
Clause 8 27

Two issues arise – how is the Architect’s dissatisfaction to be

expressed (and to whom) and how is the Architect to know when
each item of work is executed in order to be able to judge the rea-
sonable time period? Sensibly, the Architect should express any dis-
satisfaction in writing to the Contractor (with copies to any other
relevant participants – especially the Quantity Surveyor). The Archi-
tect’s knowledge of progress of the Works, through monitoring
procedures, should indicate the (approximate) time at which the
(alleged) unsatisfactory work was executed.
8.3 AI may be issued for the Contractor to open up work for inspec-
tion or to test goods and materials.
Costs to be added to the Contract Sum or may be provided in
the BQ (Provisional Sum) – including costs of making good.
However, if the tests, etc., prove the work/materials to be defec-
tive, the Contractor must bear the costs.
8.4 The four sub-clauses of Clause 8.4 give the Architect authority to
order action to be taken by the Contractor if any work, materials
or goods are not in accordance with the Contract (i.e. are found
not to comply with the specification). The authority is additional
to, and does not affect (is without prejudice to), the general powers
of the Architect.
.1 Architect may issue an AI for removal from the site of
work, goods or materials not in accordance with the Contract
requirements.
Note: (a) The Architect should give the reason for the AI, as
removal is a Variation under Clause 13.1.1.3 where the
goods, etc., are in accordance with the Contract.
(b) By Clause 27.2.1.3, the employment of the Contractor
may be determined if the defective items are not removed,
provided that the items are material to the Works.
(c) Defects becoming apparent due to, inter alia, Clause
17.2 unspecified materials, etc., must be made good at the
Contractor’s expense.
Note: Following Holland Hannen and Cubitts (Northern) Ltd v. Welsh
Health Technical Services Organisation (1985), an Architect
must take care over instructions issued regarding apparently
defective work. The authority given the Contract Clause 8.4,
is for the Architect to instruct the Contractor to remove the
defective work, etc.; the Contractor remains under an obliga-
tion to complete the work in accordance with the Contract.
28 Clause 8

.2 Architect may, given agreement of the Employer and after

consultation with the Contractor (who must consult any
NS/Cs affected), allow work, materials or goods which are not
in accordance with the Contract to remain as part of the
Works. The Architect must confirm such permission in writing
to the Contractor but the permission will:
(a) not constitute a Variation and
(b) command an appropriate deduction against the Contract
Sum.
.3 Architect may, after consultation with the Contractor (who
must consult any NS/C affected), issue AIs requiring Variations
which are reasonably necessary due to instructions to remove
defective items from site (Clause 8.4.1) or allowing defective
items to remain part of the Works (Clause 8.4.2). Such AIs:
(a) cannot provide grounds for addition to the Contract Sum
and
(b) cannot provide grounds for an extension of time.
.4 Architect may, given due regard to the Code of Practice fol-
lowing Clause 42, issue AIs to open up work for inspec-
tion/test in order to establish the likelihood/extent of any
further examples of work, materials or goods which do not
comply with the Contract. The scope of such opening up
must be reasonable having regard to the Code of Practice
and the criterion of the Architect’s reasonable satisfaction.
Irrespective of the results of the inspections/tests, no addi-
tion to the Contract Sum may be made (under Clauses 8.3
and 26). However, if the inspections/tests showed that the
work, materials and goods did comply with the Contract, the
work of opening up, inspections/tests and making good con-
stitutes a Relevant Event for which the Architect must award
an extension of time under Clause 25 (NB Clause 25.4.2).
8.5 If any work is not carried out in a proper and workmanlike manner,
as required by Clause 8.1.3, the Architect, after consultation with
the Contractor (who must consult any NS/C affected), may issue
AIs as necessary (which may require a Variation). Such AIs:
(a) cannot provide grounds for addition to the Contract Sum and
(b) cannot provide grounds for an extension of time.
8.6 Architect may (not unreasonably or vexatiously) issue an AI for the
dismissal from the Works of any person employed thereon. This
Clause 8 29

means removal from that particular project, not dismissal from

employment.
A person is defined in this context as ‘an individual or firm
(including bodies corporate)’ so firms and individuals may be dis-
missed.
Note: (a) Interim payments include only items of work properly
executed in accordance with the Contract requirements – as this
decision of compliance is that of the Architect, in theory the QS
may not deduct from his recommendation for payment unless an
AI as to unsuitability exists.
In such circumstances, however, the QS may be held not to
be fulfilling his role as a professional (expert) and so should include
a note of his valuation of any ‘suspected defective work’. It is
then for the Architect to deduct any appropriate amounts at
certification.
See Sutcliffe v Thackrah (1974).
(b) From several House of Lords decisions, the Contractor gives
warranties or implied terms:
(i) that the workmanship will be of a good standard,
(ii) that materials and goods supplied will be free from latent
and patent defects (including any under a nomination), and
that they
(iii) will be suitable for the purposes for which they are
supplied.
These may be expressly excluded, or excluded by the circum-
stances of the Contract. The Standard Form does not refer to these
matters and so, unless other Contract Documents give specific ref-
erence, they will be implied terms.
See Young & Marten Ltd v. McManus Childs Ltd (1969) and
Gloucestershire C.C. v. Richardson (1969).
Unfair Contract Terms Act, 1977 – in reference to exemption
clauses – Contractor should ensure that the above warranties are
passed on to suppliers – note that if the Architect insists on nomi-
nating a supplier who will not accept these warranties, the Con-
tractor has no liability in respect of the items in question except
for patent defects (defects obvious on reasonable examination).
Limits application of exemption clauses in regard to consumer
transactions/sales, including trading on one party’s standard con-
ditions – s3. However, contracts let by tender do not constitute
consumer sales.
Clause 9: Royalties and patent rights

9.1 All sums payable in respect of patented items are deemed to have
been included in the Contract Sum by the Contractor where
described by or referred to in the Contract Bills.
Contractor to indemnify the Employer against any claim for
infringement of patents by the Contractor.
9.2 Where Contractor uses patented items due to his compliance with
an AI, he is not liable for any patent infringements.
Any royalties, damages, etc., so arising to be paid by the Con-
tract must be added to the Contract Sum.
Note: (a) Where patents are infringed by the Contractor and the
articles in question are not referred to in the Contract Bills, the
Employer may incur liability, depending on the circumstances, pro-
vided that the articles were for proper inclusion in the Works.
(b) Prima facie, the Employer is not liable in respect of AI provi-
sion unless the AI constitutes a Variation.
(c) For the implementation of this clause, nominated items are
presumed to be the responsibility of the Architect – the Contrac-
tor will not usually be fully conversant with the contents of the
nomination at the time of tender – note, however, SMM7.

30
Clause 10: Person-in-charge

Contractor to keep a competent person-in-charge on the site (usually taken

as normal working hours or actual site working hours). This person is given
the power of Agency on behalf of the Contractor in respect of receipt of
AIs and CoW directions – hence the common title ‘Site Agent’.
All relevant persons should be informed who the Site Agent is and who
is the deputy (the person who will assume the responsibilities in the
absence of the Agent). Any changes in these personnel should be noti-
fied immediately.

31
Clause 11: Access for Architect to
the Works

Access is to be for the Architect and his representatives and at all rea-
sonable times. This applies to the site and all workshops, etc., including
those of Sub-Contractors, where items for the project are being made, so
far as procurable by the Contractor.
This will, of course, include the CoW, engineers and QS (especially for
valuation purposes).
Such access may be subject to reasonable restrictions of the Contrac-
tor or any sub-contractor in order that their proprietary rights (‘trade
secrets’, etc.) are protected.

32
Clause 12: Clerk of works

Employer is entitled to appoint a CoW.

CoW acts solely as an inspector on behalf of the Employer but under
the directions of the Architect.
Contractor to give adequate facilities for the CoW to perform his duties.
CoW directions:
(a) given to the Contractor,
(b) no immediate effect,
(c) to be valid must be in respect of a matter about which
the Conditions expressly empower the Architect to issue
instructions,
(d) confirmed in writing by the Architect within 2 working days
of being given to be of any effect – if so confirmed, then from date
of confirmation – deemed to be an AI.
Contractor has no contractual power to object to a CoW.
Provided that the Architect has properly briefed the CoW, the Employer
is responsible for him.
Leicester Board of Guardians v. Trollope (1911) shows that the Architect
is responsible for his design being followed – not avoided by a CoW being
on site.

33
Clause 13: Variations and provisional sums

13.1 Defines Variations:

.1 Alteration or modification of design, quality or quantity of the
Works, including:
.1 addition, omission or substitution of any work
.2 alteration of any kind or standard of any materials or goods
to be used in the Works
.3 removal from site of any work executed or materials or goods
for the Works which are in accordance with the Contract
(brought on site by the Contractor).
.2 The imposition by the Employer of any obligations or restric-
tions in regard to the matters set out in Clauses 13.1.2.1 to
13.1.2.4 the addition to or alterations or omission of any such
obligations or restrictions so imposed or imposed by the
Employer in the Contract Bills in regard to:
.1 access to the site or use of any specific parts of the site
.2 limitations of working space
.3 limitations of working hours
.4 the execution or completion of the work in any specific order.
Note: If sections are to be completed by specific dates in advance
of the overall completion date, then the Sectional Comple-
tion Supplement must be used.
.3 Specifically excludes omitting Contractor’s measured work
and the substitution of a Nominated Sub-Contractor to
execute that work.
Note: Must be a PC or provisional sum for a valid
nomination.
Any omissions must be genuine, otherwise the Contractor
may claim loss of profit for the ‘omissions’.
13.2 Subject to the Contractor’s right of reasonable objection (Clause
4.1.1) Architect may issue AIs requiring Variations.
Architect may sanction in writing any Variation made by the
Contractor not pursuant to an AI.
‘No Variation required by the Architect or subsequently sanc-
tioned by him shall vitiate this contract.’
34
Clause 13 35

This does not mean that the Architect may order any changes
he likes and still maintain the Contract intact.
An excessive Variation ordered by an AI would not be regarded
as a Variation under the Contract, thus payment would be on
quantum meruit.
Lord Kenyon in Pepper v. Burland (1792):
‘If a man contracts to do work by a certain plan, and that plan
is so entirely abandoned that it is impossible to trace the Contract,
and to what part of it the work shall be applied, in such case the
workman shall be permitted to charge for the whole work done
by measure and value, as if no Contract had ever been made.’
13.3 Architect to issue AIs regarding:
.1 expenditure of provisional sums included in the contract Bills,
.2 expenditure of provisional sums included in a NS/C (applies
where nomination occurs from expenditure of a provisional sum
as Clause 13.3.1).

Valuation of Variations
JCT 98 introduces three mechanisms by which a Variation can be valued.
Two of these are relatively new and follow developments elsewhere
(notably in the New Engineering and Construction Contract); these are
the 13A Quotation and the Contractor’s Price Statement (Alternative A).
The third mechanism, of valuation by the Quantity Surveyor, is the tra-
ditional JCT approach (Alternative B).
13.4.1.2 Alternative A – Contractor’s Price Statement.
13.4.1.2A1 The Contractor may submit a Price Statement
in respect of a Variation (except, confusingly,
where a quotation has been accepted under
13A, a ‘13A Quotation’). If this is the valuation
route the Contractor must submit a statement
to the Quantity Surveyor within 21 days of
receipt of the Architect’s Instruction. The state-
ment should include the price for the work,
based on the valuation rules of 13.5. It may
also include the Contractor’s direct loss and
expense and any extension of time (under 13A
quotation rules these are mandatory).
13.4.1.2A2 The Quantity Surveyor must notify the Con-
tractor, within 21 days, of the statement’s
acceptability. If it is not accepted, reasons, in a
similar format to the statement, must be given
36 Clause 13

and an amended statement provided. The

Contractor then has 14 days to accept the
amendment; if not either party may refer to
adjudication.
13.4.1.2A4.3 If not referred to adjudication then the varia-
tion is valued by the Quantity Surveyor under
13.4 Alternative B.
13.4 Alternative B
If no 13A Quotation is sought and no Alternative A Contractor’s
Price Statement submitted, or if the 13A Quotation, or Contrac-
tor’s Price Statement or amended Price Statement is rejected, then
the Variation must be valued by the Quantity Surveyor in accor-
dance with the rules in 13.5.
13.4.1.2 .1 Valuation of Variations – by the QS – in accordance with
Clause 13.5 (unless otherwise agreed by the Contractor
and the Employer – this would constitute a Variation of
the Contract and so the parties to the contract must
agree to it). Also applies to work executed by the Con-
tractor for which an Approximate Quantity is included in
the BQ.
Note: The payment rules are applicable only to Variations as
defined by the Contract. If in doubt, therefore, the Con-
tractor should implement the authority for an AI proce-
dure as Clause 4.2.
See Myers v. Sarl (1860): Drawings, even if prepared in the Archi-
tect’s office and stamped, must be signed by the Architect to be valid
authority to execute work. Possibly, however, the signature of a clerk
preparing the drawings on behalf of the Architect would suffice.
(b) Valuation of Variations and valuation of work for which an
Approximate Quantity is included in the bills of quantities
included in the Numbered Documents (as annexed to Agree-
ment NSC/A) – Nominated S/C’s work – to be in accordance
with the relevant provision of NSC/C (Sub Contract form);
unless otherwise agreed by NS/C and Contractor, with
Employer’s approval.
.2 Valuation of work constituting a PC Sum arising due to AIs
regarding expenditure of a provisional sum for which the
Contract has had a tender accepted (Clause 35.2) must be
valued in accordance with that successful tender, not the
normal Variation provision.
Clause 13 37

13.5 .1 Variations constituting additional or substituted work and

work for which an Approximate Quantity is included in
the BQ which can be valued by measurement – valuation
to be of:
.1 similar character, executed under similar conditions does not
significantly change quantity of work in Contract Bills – rates
and prices in BQ shall determine the valuation.
.2 similar character, not similar conditions and/or significantly
changes quantity of work in BQ – rates and prices in BQ to
form basis for valuation (i.e. pro rata prices) with a fair
allowance for the difference.
.3 not of similar character to BQ – fair rates and prices.
Rather contentious – can varied work really be of similar charac-
ter? What is a significant change in quantity? How much to pro
rata? What is a fair valuation? Perhaps a guide is to read ‘identical’
for ‘similar’.
.4 Approximate Quantity is close to the quantity of work
required – rates and prices in BQ to be used.
.5 Approximate Quantity is not a reasonably accurate forecast
of the quantity of work required – pro rata rates/prices to
be used.
Clauses 13.5.1.4 and .5 apply only if the work is the same in all
respects as that described in the BQ except for the quantity
required. Hence, if the specification/conditions of the work change,
the full valuation of Variations rules apply.
.2 Variations requiring omission of work from BQ: valuation of
work omitted to be at BQ rates.
.3.1 Measurement to be in accordance with the principles used
to prepare the BQ (SMM7).
.2 Allowances to be included in respect of any appropriate per-
centages or lump sums in BQ (e.g. profit, attendances on
NS/Cs).
.3 Appropriate adjustment to be made for preliminaries. This
provision does not apply in respect of compliance with an
AI for the expenditure of a provisional sum for defined work
(see SMM7 General Rules 10.1 to 10.6).
.4 Where additions or substitutions cannot properly be valued
by measurement, valuation shall comprise:
38 Clause 13

.1 Prime cost of the work plus percentage additions as set out

by the Contractor in the BQ (usually separate percentages for
labour, plant, materials). Prime cost – calculate in accordance
with ‘Definition of the Prime Cost of Daywork carried out
under a Building Contract’ current at the Date of Tender.
.2 Specialist trades definition of Prime Cost of Daywork to be
used as appropriate.
(Electrical Contractors’ Association – Electrical Contractors’
Association of Scotland – Heating and Ventilating
Contractors’ Association.)
Vouchers stating:
time daily spent on the work,
workmen’s names (usually including grade),
plant,
materials,
must be sent to Architect, or his authorised representative for ver-
ification not later than the end of the week following that during
which the work is executed. Verification is usually by signature of
the appropriate person – if in doubt send to the Architect.
.5 If a Variation substantially changes the conditions under
which other work is executed, that other work may be valued
in accordance with the rules for valuing Variations.
The provision also applies to other work subject to changes
due to:
(a) compliance with an AI for expenditure of a provisional
sum for undefined work
(b) compliance with an AI for expenditure of a provisional
sum for defined work – where the work executed differs
from the work described in the BQ
(c) execution of work for which an Approximate Quantity is
included in the BQ – where the quantity executed is dif-
ferent from that stated in the BQ.
.6.1 Valuation of Performance Specified Work – to include
allowance for addition/omission of any work involved in
preparation and production of drawings, schedules or other
documents.
.2 Valuation of additional/substituted work related to Perfor-
mance Specified Work:
Clause 13 39

(a) work of similar character – BQ (or Analysis) rates or

prices with allowances for changed conditions/quantities
changed significantly from those in BQ or Contractor’s
Statement.
(b) no work of similar character in BQ or Contractor’s
Statement – a fair valuation.
.3 Valuation of omission of work relating to Performance
Specified Work – at rates/prices in the BQ or the Analysis.
.4 Any valuations under Clause 13.5.6.2 and .3 must include any
appropriate adjustments of preliminaries.
.5 Valuations of additional/substituted work relating to Perfor-
mance Specified Work by daywork – the proviso to Clause
13.5.4 applies (vouchers, etc. – see above).
.6 If compliance with an AI requiring a Variation or expenditure
against a provisional sum differs from the information in the
BQ (both in regard to Performance Specified Work) and sub-
stantially changes the conditions under which any other work
is executed, such work affected shall be treated as being the
subject of an AI requiring a Variation and valued under the
provisions for valuing Variations (Clause 13.5).
.7 Excluding additions, omissions and substitutions of work, the
valuation of work or liabilities directly associated with a Varia-
tion which cannot be reasonably valued as above, shall be
the subject of a fair valuation, e.g. part load delivery charges
where the bulk of the items in question have already been
delivered.
An allowance for disturbance to the regular progress of the
works and/or for any direct loss and/or expense may be
included in the valuation of Variations under Clause 13.5 only
where it is not reimbursable under any other Contract Clause.
Usually, such ‘disturbance cost’ will be considered under
Clause 26 – the provision of clause 13.5 being used only as
a ‘last resort’.
13.6 QS to allow Contractor to be present and take all necessary notes
when QS is measuring work to value Variations.
13.7 Contract Sum to be adjusted to take account of all valuations of
Variations.
Thus, where a Variation has been executed but not measured
and valued, it is reasonable to include an ‘on account’ valuation in
interim payments until formal valuation has been finalised.
40 Clause 13

Note: The valuation of Variations, howsoever arising, is to be exe-

cuted by the QS (including provisional sum items) unless the
Employer and Contractor themselves agree something different.
The Architect is involved only where a Contractor claims for reim-
bursement of loss/expense due to the regular progress of the works
being materially affected (disturbed).
Clause 13A: Variation Instructions –
Contractor’s quotation in compliance with
the instruction

By Clause 13.2.3 an Instruction requiring a variation may state that the

treatment and valuation of the variation are to be in accordance with 13A.
The Contractor has 7 days to disagree and then the Instruction must be
valued by 13.4 Alternative A or B.
13A.1.1 The Instruction shall provide sufficient detail to allow the Con-
tractor to provide a Quotation (a 13A Quotation).
13A.1.2 The Contractor has 21 days from receipt of the Instruction to
submit his 13A Quotation (including 3.3A Quotations (NSC) in
respect of any NSC) and that 13A Quotation remains open for
acceptance for 7 days.
13A.2 The 13A Quotation is an all-inclusive price for the variation,
including:
.1 the value of the work (including NSC work) plus allowances
for preliminary items
.2 the adjustment to time for completion
.3 the amount in lieu of any ascertainment under Clause 26 of
direct loss and expense
.4 the cost of preparing the 13A Quotation.
Where specifically requested the 13A Quotation shall provide
indicative information statements on
.5 the additional resources required
.6 the method of carrying out the Variation.
13A.3.1 The Employer may accept a 13A Quotation and the Architect
shall immediately confirm to the Contractor ‘a confirmed
acceptance’.
13.4 If the 13A Quotation is not accepted the Architect either
instructs that the Variation is carried out, and valued via either
Alternative A or B, or that the work is not to be carried out. If
the work is not carried out the Contractor shall be paid a fair
and reasonable amount in respect of the preparation of the
Quotation.

41
Clause 14: Contract Sum

14.1 ‘The quality and quantity of the work included in the Contract Sum
shall be deemed to be that which is set out in the contract Bills’.
Note: Clause 2.2 – The Bills of Quantities must be in accordance
with SMM7. Any items not so included must be specifically noted
with an indication of how measured, usually indicated thus:
‘Notwithstanding SMM Clause No., work item is measured descrip-
tion of how measured for BQ.’
Such a statement will usually occur in the Preambles section of the
BQ.
Clause 14.1 is upheld in its expressed limitation of authority of
the BQ by:
English Industrial Estates Corporation v. George Wimpey & Co. Ltd
(1973)
Gleeson MJ Ltd v. London Borough of Hillingdon (1979).
14.2 Contract Sum fixed as a lump sum; the only adjustments permis-
sible are those set out in the Conditions of Contract (e.g. valuation
of Variations).
Subject to QS’s preparation errors which are covered by Clause
2.2.2.2, any errors (arithmetic, etc.) are deemed to have been
accepted by the parties and are non-adjustable.
Note:
(a) Provisions of Code of Procedure for Single Stage Selective
Tendering, 1998.
(b) Professional responsibilities, especially negligence.
(c) JCT Standard Form is a Lump Sum Contract with provision
for interim payments. Although the Lump Sum nature is
diluted by items in the Bills of Quantities the Contractor
agrees to carry out the work for the Contract Sum – not to
carry out the work for the rates in the Bills. These rates are
only for the valuation of variations.

42
Clause 15: Value added tax –
supplemental provisions

15.1 Defines VAT – introduced by Finance Act 1972. Under the control
of the Customs and Excise.
15.2 Contract Sum is always exclusive of VAT.
15.3 Where any items become exempt from VAT after the Base Date –
Employer to pay the Contractor the loss of input tax he would
otherwise have recovered.

43
Clause 16: Materials and goods unfixed
or off-site

16.1 Unfixed materials/goods delivered to, placed on or adjacent to the

Works and intended therefore may be removed only for use on the
Works, unless removal has been agreed in writing by the Architect.
Such consent not to be unreasonably withheld.
Unfixed materials/goods (as above) – value of which has been
included in an Interim Certificate which has been paid are the prop-
erty of the Employer. The Contractor is in the position of a bailee,
expressly responsible for loss or damage to them; but subject to
Clause 22B or C if applicable (fire, etc., Employer to insure).
Until an Interim Certificate, as denoted above, is honoured, the
property in the goods remains with the appropriate party as per
the sale agreement, governed by the Sale of Goods Act (usually
the Contractor).
Following Dawber-Williamson Roofing Ltd v. Humberside County
Council (1979); under sub-contract in which no express terms cover
the passing of property in materials/goods on site, the title does
not pass until the materials/goods are fixed.
See Stansbie v. Troman (1948): where items on site are owned
by the Employer, common law requires the Contractor to take rea-
sonable care to protect them from damage, theft, etc. This, prob-
ably, also applies to Sub-Contractors’ items on site.
16.2 Applies to materials/goods stored off site – often applies to nomi-
nated items due to their high value. Once the Employer has paid
the Contractor for them (clause 30.3) and so the property has
passed to the Employer, the Contractor has responsibilities:
(a) to remove them only for incorporation in the Works
(b) for costs of storage, handling, insurance until delivered to the
Works, whereupon Clause 16.1 applies
(c) for loss or damage.
Note: S.16 Sale of Goods Act – property in unascertained
goods cannot pass to the purchaser unless and until the goods are
ascertained.
Naturally, many of these responsibilities are passed on by the
Contractor to the Supplier or Sub-Contractor in most cases.
In the absence of any express terms in a building Contract,
materials on site do not become the property of the Employer until

44
Clause 16 45

they have been made part of the project; ‘fully and finally incor-
porated into the Works’ is a common phrase in this regard.
Clearly in the 1998 JCT standard form, this general principle is
overridden by the express provisions of the Contract – Clause 16.
The requirement for listed items, either uniquely identified or
not, of Clause 16 materials has implications for certificates and pay-
ments (Clause 30.3).
Clause 17: Practical Completion and
defects liability

17.1 As soon as the Architect considers that Practical Completion of the

Works has been achieved, he must issue a Certificate to that effect
provided that the Contractor has provided any as-built drawings,
etc. concerning Performance Specified Work in accordance with
Clause 5.9. For all the purposes of the contract, Practical Com-
pletion is deemed to have occurred on the day named in that
Certificate.
Practical Completion is not defined in the contract but is nor-
mally understood to be when the Works are complete for all prac-
tical purposes, any outstanding items of work being of only a minor
or remedial nature such that they would not materially affect the
proper functioning of the building.
Note: Practical Completion is distinct from and not applicable to
the doctrine of Substantial Completion where, if a party can
show that he has ‘substantially performed’ his obligations,
he can successfully sue for the price under an entire or lump
sum contract provided that he gives appropriate credit
for any deficiencies in the whole, including uncompleted
obligations.
See Appleby v. Myers (1867) – following Cutter v. Powell (1795) –
Blackburn J:
‘There is nothing to render either it illegal or absurd in the
workman to agree to complete the whole, and to be paid when
the whole is complete, and not till then.’
If a builder failed to complete an entire contract he could claim
neither quantum meruit nor in equity.
Sumpter v. Hedges (1898) – A.L. Smith LJ:
‘The law is that where there is a contract to do work for a
lump sum, until the work is completed the price of it cannot be
recovered.’
Dakin H. & Co. Ltd v. Lee (1916): Under a lump sum building con-
tract, defects or omissions amounting only to negligent perfor-
mance (not abandonment of the contract, etc.) did not preclude
a successful claim for the contract sum less only the amount nec-
essary to make the work accord with the specification.

46
Clause 17 47

Naturally the question is one of degree and for this rule to apply
the omissions or defects should be of a relatively minor nature.
Hoenig v. Issacs (1952) – Denning LJ:
‘It was a lump sum contract, but that does not mean that entire
performance was a condition precedent to payment. Where a con-
tract provides for a specific sum to be paid on completion of spec-
ified work, the courts lean against a construction of the contract
which would deprive the contractor of any payment at all simply
because there are some defects or omissions.’
Thus, it may be concluded that the JCT Standard Form 1998
Edition is a lump sum contract with provision for Interim Payments.
Note: following observations in Dakin v. Lee and Hoenig v. Isaacs:

(a) the builder cannot recover if he abandons the contract

(subject to the express terms of the agreement)
(b) contracts which provide for retention money to be paid on
completion might require entire performance in the strict
sense – but, probably, in relation only to the retention releases
rather than Interim Payments under the Contract.
(c) J. Jarvis & Sons Ltd v. Westminster Corporation (1970): Practi-
cal completion:
‘What is meant is the completion of all the construction work
that has to be done.’
(d) H.W. Nevill (Sunblest) Ltd v. Wm Press & Son Ltd (1980):
‘I think that the word “practically” in Clause 15(1)[JCT 63]
gave the Architect discretion to certify that William Press had
fulfilled its obligation under Clause 21(1) where very minor,
de minimis, work had not been carried out but that if there
were any patent defects in what William Press had done,
the Architect could not have given a Certificate of Practical
Completion.’
17.2 The Appendix provides for the usual 6 months DLP to be varied.
Defects, shrinkages and other faults which appear within the
DLP and are due to materials and workmanship not in accordance
with the Contract must be:
(a) Specified on a schedule of defects by the Architect, to be
delivered as an AI to the Contractor not later than 14 days
from the expiration of DLP.
48 Clause 17

(b) made good by the Contractor at his own cost (unless subject
to an AI, with the Employer’s consent, not to make good any
such defects and to reduce the Contract Sum accordingly)
and within a reasonable time.
17.3 Despite the provision of Clause 17.2, such defects etc., including
damage caused by frost prior to Practical Completion, may be the
subjects of an AI for their making good – Contractor to comply
within a reasonable time and normally at his own cost. (Again,
subject to a possible AI not to make good, and, then to reduce the
Contract Sum accordingly.)
No such AIs may be issued after delivery of the schedule of
defects or 14 days from the expiration of DLP.
This Clause enables individual defects, usually of a more major
nature, to be required to be made good prior to the issue of the
full defects list.
There is no provision for an interim defects list except by this AI
provision but the issue of such a list is quite common in practice.
Thus, it is sensible and usual for the defects schedule to be pre-
pared and issued as late as possible such that all defects arising
may be properly included.
Any defects which appear after the expiration of DLP are not
covered by the Contract and so any action for their making good
would have to be at common law.
Note: Statutes of Limitations provisions.
17.4 When the defects specified by the AIs and/or the schedule of
defects have, in the Architect’s opinion, been made good, he must
issue a Certificate of Completion of Making Good Defects.
This Certificate is a prerequisite for:
(a) Final Certificate – Clause 30.8,
(b) release of the balance of retention – Clause 30.4.1.3
17.5 Contractor must make good only frost damage which is due to
frost prior to Practical Completion. If frost damage becomes appar-
ent after Practical Completion the Architect must certify that such
damage is due to frost which occurred prior to Practical Comple-
tion for the Contractor to be required to make it good under the
Contract. If no such Certificate is issued, the Contractor is entitled
to claim payment for the work involved.
Clause 18: Partial possession by Employer

18.1 Prior to the date(s) of issue of the Certificate(s) of Practical Com-

pletion, the Employer may wish to take possession of any part(s)
of the Works. If the consent (not unreasonably withheld) of the
Contractor has been obtained, then notwithstanding anything
express or implied elsewhere in the Contract, the Employer may
take possession. Upon such taking of possession, the Architect must
issue a written statement to the Contractor, on the Employer’s
behalf, which identifies the part(s) of the Works taken into posses-
sion (‘relevant part’) and which specifies the date on which the
Employer took possession (‘relevant date’).
In such instances, the following must occur:
.1 Practical Completion is deemed to have occurred and the DLP
to have commenced on the relevant date for the relevant
part, for the following purposes only:
(a) Clause 17.2 – schedule of defects
(b) Clause 17.3 – AIs re defects
(c) Clause 17.5 – damage by frost
(d) Clause 30.4.1.2 – Retention ( –21 release).
.2 Certificate of Completion of Making Good Defects of the rel-
evant part to be issued at the appropriate time (see usual pro-
visions regarding the issue of this Certificate).
.3 The obligation to insure the relevant part under Clause 22A
(contract insuring) or Clause 22B.1 or 22C.2 (Employer insur-
ing) terminates from the relevant date. Where Clause 22C
applies, the obligation of the Employer to insure under Clause
22C.1 includes the relevant part from the relevant date.
.4 Liability to pay liquidated damages in respect of the relevant
part ceases on the relevant date. Any such liability (Clause 24)
in respect of the remainder of the Works which arises on or
after the relevant date is reduced on a pro-rata basis. (The
value of the relevant part pro-rata the Contract Sum.)
English Industrial Estates Corporation v. George Wimpey
& Co. Ltd (1973) stresses the importance of the Architect’s
Certificate.

Clause 19: Assignment and sub-contracts

Note: the difference between assignment and sub-letting.

Assignment the transfer of one party’s rights and obligations under a
contract to a third party. The consent of the other party to
the original contract is often required (e.g. debt factoring).
Obligations cannot be transferred unless attached to some
right(s).
Sub-letting where one party’s contractual obligations are carried out
on his behalf by a third party. The original parties to the
contract retain full rights and responsibilities under that
contract. Often, the third party will be in a contractual
(Sub-Contract) relationship with the party for whom he
carried out obligations vicariously.
19.1.1 Neither party may assign the Contract without the written
consent of the other.
.2 If the Appendix states that Clause 19.1.2 applies and if the
Employer transfers his freehold or leasehold interest in the
premises comprising the Works or grants a leasehold interest in
such premises, at any time after Practical Completion, the
Employer may assign to the new freeholder or leaseholder
the right to bring arbitration or litigation proceedings (in the
name of the Employer) to enforce any of the terms of this
Contract.
Any enforceable agreements regarding this Contract made
between the Employer and Contractor prior to any such assign-
ment remain intact and, via estoppel, are part of the assignment.
(This is an expression of a basic legal premise regarding transfers
of title ‘nemo dat quod non habet’.)
Note:
(a) This provision for assignment by the Employer does not
require the written consent of the Contractor.
(b) The rules of Limitation will remain.
(c) The assignment must be executed correctly – in accordance
with the Contract, naming the assignee correctly, etc. (of par-
ticular importance to groups of companies).
19.2.1 Any Sub-Contractor which is not a NS/C is a Domestic Sub-
Contractor.

50
Clause 19 51

.2 The Contractor must have the written consent of the Architect to

sub-let any part of the Works. Such consent must not be unrea-
sonably withheld.
Following Clause 2.1, the Contractor retains overall responsibil-
ity for the execution and completion of the Works in accordance
with the Contract, irrespective of any sub-letting.
Note: LA common requirements to sub-let only to local firms –
usually within a prescribed area.
There is no requirement for the Architect to approve domestic
Sub-Contractors.
19.3 .1 Work measured in the Contract Bills and priced by the Con-
tractor, where the BQ requires that work to be carried out by
a person selected by the Contractor from a list contained in
the BQ.
.2.1 The list must contain at least 3 persons. The Employer (or the
Architect on his behalf) or Contractor may, with the consent
of the other party, add persons to any such list prior to the
execution of a binding Sub-Contract in respect of that work.
.2 If, prior to the execution of the Sub-Contract, less than 3
persons named in a list are able and willing to carry out the
work:
either the Employer and Contractor by agreement add
further names to the list to make it at least 3 names
long,
or the work may be carried out by the Contractor who
may sub-let it to a Domestic Sub-Contractor under
Clause 19.2.
.3 A person selected from such a list is to be a Domestic Sub-
Contractor.
Note: If a list is altered by having names added, such additions
must be inserted in the BQ and initialled by the Employer
and Contractor as they represent changes in the terms of
the Contract.
19.4.1 Any domestic sub-contract must provide for the employment of
that Domestic Sub-Contractor to be determined immediately that
the employment of the main Contractor is determined under the
contract.
.2 Any domestic sub-contract must provide that:
52 Clause 19

.1 Unfixed materials/goods on site of the Domestic Sub-

Contractor must not be removed except for use on the
Works, unless the Contractor has consented in writing to
such other removal. The consent must not be withheld
unreasonably.
.2 Where, in accordance with Clause 30, the value of unfixed
materials/goods on site has been included in an Interim Cer-
tificate against which the Employer has discharged payment
to the Contractor (usually, by making the payment), those
materials/goods are deemed to be the property of the
Employer. The Domestic Sub-Contractor may not deny that
the property in the materials/goods has passed to the
Employer.
.3 If the Contractor pays the Domestic Sub-Contractor for
unfixed materials/goods on site prior to the Employer’s prop-
erly discharging payment to the contractor for them, the
property in those materials/goods, passes to the Contractor
upon the payment’s being made to the Domestic Sub-
Contractor.
.4 The Operation of Clauses 19.4.2.1 to 3 is without prejudice
to the provision of Clause 30.3.5.
Clause 19.4.2 is intended to overcome difficulties found to
exist over the title to unfixed materials/goods on site in Dawber-
Williamson Roofing Ltd v. Humberside County Council (1979), in
instances where domestic sub-contracts include retention of title
provision (‘Romalpa Clauses’ – Aluminium Industrie Vaassen v.
Romalpa (1976)). Clauses 19.4.2.2 and unfixed materials/goods
on site for which payment has been discharged under the provi-
sions of the main Contract, even in cases where the Contractor
does not have good title to those materials/goods to pass on –
this is the objective of the ‘not deny’ stipulation in Clause
19.4.2.2.
Note: The requirement is to discharge payment not to make the
payment for valid title to pass; this provision is to accom-
modate set-off, etc.
19.5.1 Provisions for Nominated Sub-Contractor – see Part II of the
Contract.
The Contractor retains overall responsibility for executing
and completing the Works in accordance with the Contract
irrespective of work executed by NS/Cs unless the Contract states
otherwise.
Clause 19 53

.2 Unless the Contractor is acting as a Nominated Sub-

Contractor (Clause 35.2) he is not required to do any work
which is to be carried out by a Nominated Sub-Contractor.
N.W. Regional Hospital Board v. Bickerton (1969): If a first nomi-
nation fails before the work under a PC Sum is completed, there
is a duty upon the Architect to re-nominate.
Note: Non-compliance with the sub-letting provisions (Clause
19.2 etc.) is a ground for determination of the contractor’s
employment (Clause 27.1.4).
British Crane Hire Ltd v. Ipswich Plant Hire Ltd (1975): If there is
a ‘course of dealing’ between the parties (frequent transactions
probably using a standard contract) or if the terms of agreements
are standard (e.g. national plant hire agreement), even if not
specifically included in forming a contract, they may be implied to
give the relationship ‘business efficacy’.
Clause 20: Injury to persons and property
and indemnity to Employer

See also Practice Note 22.

20.1 The Contractor to be liable for and must indemnify the Employer
against any expense, liability, loss, claim or proceedings at statute
or common law for personal injury or death due to the carrying
out of the Works.
The only exception is the extent to which negligence on the
part of:
(a) the Employer
(b) any person for whom the Employer is responsible
(c) any person(s) employed or engaged by the Employer to
whom Clause 29 refers
caused the injury/death. (Thus if the Employer’s negligence is 30%
to blame for the injury, the indemnity covers 70% of the Employer’s
loss.)
20.2 Similar to Clause 20.1, but:
(a) refers to real or personal property
(b) excludes the Works etc. as Clause 20.3
(c) excludes damage to existing structures, contents etc. under
Clause 22C.1 – Employer to insure
(d) damage must be due to any negligence, breach of statutory
duty, omission or default of the Contractor or persons for
whom the Contractor is responsible. Includes all persons
authorised to be on the site except:
(i) the Employer
(ii) persons employed, engaged or authorised by the
Employer
(iii) persons employed, engaged or authorised by any local
authority
(iv) persons as (iii) but employed, etc. by a statutory under-
taker and who are executing work solely in pursuance of
its statutory rights or obligations.

54
Clause 20 55

20.3.1 ‘Property real or personal’ in Clause 20.2 subject to partial pos-

session, excludes the Works, materials on site and work executed
up to and including the earlier of:
(a) the date of issue of the Certificate of Practical Completion, or
(b) the date of determination of the employment of the Con-
tractor (whether or not disputed) under Clauses 27 or 28 or
22C.4.3, if applicable.
Thus the Contractor is responsible for these items and so should
effect appropriate insurance.
.2 If partial possession has occurred under Clause 18, the relevant
part is excluded from the Works or work executed under Clause
20.3.1.
The purpose of indemnity is to protect against legal respon-
sibility or to compensate; insurance proves a fund to enable the
indemnifying party to make any payments which may arise. Insur-
ance does not affect the obligations of the parties. Thus, it is usual
for indemnity and insurance provisions to be considered together,
the former apportioning risks and the latter dealing with the set-
tlement of claims in respect of prescribed liabilities.
Law Reform (Married Women and Tortfeasors) Act, 1935:
Clause 20 covers tortious liability, thus the Act is of relevance.
If there were joint (two or more) tortfeasors and only one were
sued by a plaintiff and, thereby, had to pay damages, that tort-
feasor could recover from the other, joint tortfeasors a contribu-
tion to the damages paid in proportion to the liabilities of each
tortfeasor in respect of the tortious act.
Such does not apply if one joint tortfeasor is to indemnify the
other(s); the party who is to indemnify the other(s) bears the full
liability.
Here the contractor must indemnify the Employer.

Farr AE Ltd v. Admiralty (1953)
A.M.F. International v. Magnet Bowling Ltd & G.P. Trentham Ltd
(1968).
Clause 21: Insurance against injury to
persons or property

See also Practice Note 22

21.1.1.1 The Contractor must take out and maintain insurance in
respect of liabilities placed upon him under Clauses 20.1 and
20.2, i.e.:
(a) for personal injuries etc., arising from the Works (except
if due to Employer’s, etc. negligence)
(b) for damage to real or personal property arising from the
Works due to the negligence, etc. of the Contractor, etc.
Note exclusions of persons causing the damage under
Clause 20.2; item (d).
.2 Insurance for injuries to or death of Contractor’s employees
which occur during the course of their employment must
comply with the provisions of the Employers’ Liability (Com-
pulsory Insurance) Act 1975 including any amendments, etc.,
to that act.
The minimum insurance cover required for all other claims
under Clause 21.1.1.1 for any one occurrence or series of
occurrences arising out of one event is stated in the Appen-
dix.
Beyond the scope of the provisions of the Contract, the
Contractor is required to comply with all statutory provisions,
including those regarding insurance, to be effected by an
employer.
21.1.2 The Contractor and Sub-Contractors must send documentary evi-
dence to the Architect for inspection by the Employer that the
insurances required by Clause 21.1.1.1 have been taken out and
maintained whenever reasonably required to do so by the
Employer.
On any occasion, the Employer may require (not unreasonably
or vexatiously) such documentary evidence to be relevant policy
(policies) and premium receipt(s).
.3 If the Contractor defaults in:
(a) taking out the insurance, or
(b) maintaining the insurance

56
Clause 21 57

as required under Clause 21.1.1.1., the Employer may effect the

appropriate insurance and recover the premium amounts (paid
or payable) from the Contractor:
(a) by deduction from payments to the Contractor under this
Contract, or
(b) as a debt of the Contractor.
21.2.1 If the Appendix states that insurance under this Clause (21.2.1)
may be required by the Employer, upon being so instructed by
the Architect, the contractor must take out and maintain a Joint
Names Policy (the joint names being those of the Employer and
the Contractor) for the amount of indemnity stated in the Appen-
dix. A policy of insurance taken out for the purposes of clause
21.2 should extend until the end of the DLP. The insurance is
against:
‘. . . any expense, liability, loss, claim or proceedings which the
Employer may incur or sustain by reason of any damage to any
property other than the Works and Site Materials caused by col-
lapse, heave, vibration, weakening or removal of support or low-
ering of groundwater . . .’
due to the execution of the Works.
Exceptions are injury or damage:
.1 for which the Contractor is liable under Clause 20.2
.2 due to errors or omissions in the design
.3 which reasonably can be foreseen to be inevitable (due to the
nature or the manner of its execution (Rylands v. Fletcher
(1868))
.4 for which the Employer should insure under Clause 22C.1, if
applicable
.5 to the Works and Site Materials brought on to the site of the
Contract for the purpose of its execution except insofar as
any part or parts thereof are the subject of a Certificate of
Practical Completion – the Employer then takes responsibil-
ity
.6 & .7 arising from war risks or the Excepted Risks (see definition of
Excepted Risks in Clause 1.3)
.8 directly or indirectly caused by or arising out of pollution or
contamination during the period of insurance. Then an
exception to the exception – the Contractor is responsible
58 Clause 21

for sudden, identifiable, unintended and unexpected

incidents.
.9 which result in the Employer incurring costs or paying sums
in respect of breach of contract, again with an exception to
the exception, where such costs or payment would have
occurred in the absence of any Contract
This insurance covers the Employer’s potential liability as a joint
tortfeasor – if the Contractor wishes to insure in respect of his
potential liabilities in this regard, he must do so in addition to the
insurance required by this Clause.
Under a joint names policy, the insurers cannot recover payment
to one insured party from the other insured party where the latter’s
action caused the loss (i.e. subrogation cannot occur).
See Gold v. Patman & Fotherington Ltd (1958).
The insurance also will provide protection for the Employer
where there is no negligence on the part of the Contractor, etc.
It would be prudent for the insurance under Clause 21.2.1 and
that effected by the Contractor in respect of Clause 20.2 to be with
the same insurer, thereby avoiding potential argument between
insurers about which is liable.
.2 The Clause 21.1.1 insurance to be placed with insurers approved
by the Employer. Contractor to send policy (policies) and premium
receipt(s) to the Architect for deposit with the Employer.
.3 Amounts paid by the contractor to effect these insurances are to
be added to the Contract Sum.
.4 If the Contractor defaults in respect of these insurance require-
ments, the Employer may effect the insurance required.
21.3 Damage and injury caused by Excepted Risks are excluded from:
(a) indemnity provisions of Clauses 20.1 and 20.2
(b) insurance requirements of Clause 20.1.1
Thus, the Excepted Risks are assumed by the Employer.
Clause 22: Insurance of the Works

See also Practice Note 22.

If it is not possible to effect insurance in respect of all the ‘Specified Perils’
(see Clause 1.3 for definition), the matter should be resolved at Tender stage
and the Contract amended accordingly (this should not be necessary).
Which of the three alternative Clauses will be used depends upon the
circumstances:
22A Contractor to insure (new building)
22B Employer to insure (new building)
22C Employer to insure – alterations/extensions to an existing
structure
The explanation for the three alternatives is that the Employer may
choose to insure new building work since an Employer may be better
placed to secure an economic policy; and that only the Employer can
insure existing buildings.
Each insurance comprises a Joint Names Policy for All Risks Insurance
for the Works. Clause 22C insurance further comprises a Joint Names
Policy for insurance of the existing structure and their contents owned by
the Employer or which are the Employer’s responsibility against loss or
damage caused by the Specified Perils.
22.1 Which Clause, 22A, 22B or 22C is to apply must be stated in the
Appendix.
Note: A new building, if attached to an existing building by a link
bridge or similar connection, depending on the nature of
the connection of the buildings, may be deemed to be an
extension to the existing building for insurance purposes.
Hence, care must be taken to ensure that the correct insur-
ance is stipulated and effected otherwise, due to the nature
of insurance contracts (uberrimae fidae), the ‘apparent’
insurance may be void.
22.2. Sets out relevant definitions of terms, namely:
All Risks Insurance – which gives cover against any physical loss or
damage to work executed and Site Materials.
Costs of repairing, replacement or rectification are excluded in
respect of:
.1 defects due to
.1 wear and tear

59
60 Clause 22

.2 obsolescence
.3 deterioration, rust or mildew;
.2 work executed or Site Materials lost or damaged through
defective design or work execution, etc. of those items, and
any work executed which is lost or damaged as a conse-
quence of such failure where the lost or damaged work relied
for support or stability on the items which failed;
Note: Site Materials do not feature in the second part of this sub-
Clause.
See also: D & F Estates Ltd v. Church Commissioners for England
(1989).
.3 loss or damage caused by or arising from
.1 any consequence of war, invasion etc., nationalisation,
requisition, loss, destruction or damage to property by or
under orders of any government, public, municipal or
local authority;
.2 disappearance or shortage, only if revealed when an inven-
tory is made or is not traceable to an identifiable event;
.3 an Excepted Risk.
If the Contract is in Northern Ireland two further exclusions apply:
.4 civil commotion;
.5 Terrorists acts – a terrorist is a member of or somebody
acting for an organisation which is proscribed under the
Northern Ireland (Emergency Provisions) Act, 1973; ter-
rorism is violence for political ends including violence to
scare the public or a section thereof.
Site Materials – all unfixed materials and goods delivered to, placed
on or adjacent to the Works and intended for incorporation therein.
Note: No definition of temporary works is given but, normally, is
defined as works executed by the Contractor to enable the per-
manent Works to proceed.
The insurance does not provide cover for temporary works, plant
and similar items of the Contractor, etc.; insurance of such items
should be effected by the Contractor (and Sub-Contractors).
All risks insurance policies are not standard. The Contract lists
risks to be covered by the insurance, but it is probable that
the working of policies will vary (as may the cover offered). It is
Clause 22 61

essential to check that the requisite cover is afforded by the policy

(perhaps particularly by scrutiny of exclusion clauses in the policy)
prior to actually effecting the insurance. The JCT has checked to
ensure that the required cover can be obtained.
22.3.1 The assured (Contractor under Clause 22A; Employer under
Clauses 22B and 22C) must ensure that the Joint Names Policy(s)
(under the applicable of Clauses 22A.1, 22A.3, 22B.1, 22C.1,
22C.2):
(a) provide for recognition of each NS/C as an insured under the
relevant Joint Names Policy, or

(b) include a waiver by the insurers of their rights of subrogation

(if any) against any NS/C.
Thus, under alternative (b), the insurer waives any right to sue
any NS/C for damage caused by the NS/C and covered by (and
thence reimbursed under) the Joint Names Policy.
The recognition or waiver for NS/Cs is in respect of loss or
damage to the Works and Site Materials caused by Specified Perils
under Clauses 22A, 22B and 22C.2. Where Clauses 22C.1 applies,
the recognition or waiver applies to loss or damage to the exist-
ing structures and relevant contents caused by Specified Perils.
Any such recognition or waiver applies up to and including the
earlier of:
(i) date of issue of Certificate of Practical Completion of the Sub-
Contract Works – NSC/C, Clause 2.11
(ii) date of determination of the employment of the Contractor
(whether disputed or not) under Clause 27, 28, or 22.C.4.3
if applicable.
The provisions of Clause 22.3.1 also apply to any Joint Names
Policy effected under the Contract where the party who was
required to insure has not effected the insurance and the Joint
Names Policy has, in consequence, been taken out by the other
party (e.g. Employer has effected the insurance under Clause
22A.2).
22.3.2 The provisions of Clause 22.3.1 regarding recognition or waiver
apply also to Domestic Sub-Contractors. Such recognition or
waiver continues up to and including the earlier of:
(i) the date of issue of any certificate or document which states
that the Domestic Sub-Contract Works are practically com-
plete, or
62 Clause 22

(ii) the date of determination of the Contractor’s employment as

Clause 22.3.1.
The provisions of Clause 22.3.1 do not apply where the Joint
Names Policy is effected under Clauses 22C.1 or 22C.3.
Clause 22A: Erection of new buildings –
All Risks Insurance of the Works
by the Contractor

22A.1 Contractor to take out and maintain a Joint Names Policy for All
Risks Insurance. The minimum scope of cover is denoted in Clause
22.2. The amount of cover required is the full reinstatement value
of the Works plus any percentage to cover professional fees as
stated in the Appendix.
Subject to Clause 18.1.3., the insurance must be maintained up
to and including the earlier of:
(a) the date of issue of the Certificate of Practical Completion,
or
(b) the date of determination of the employment of the Con-
tractor under Clause 27, 28 or 28A (whether the validity of
such determination is contested or not).
Note:
(i) Especially during times of high inflation, it is essential to
ensure that the cover is adequate for the full reinstatement
value, as required – including Variations, etc.
(ii) Where an Extension of Time is awarded, it is essential to
ensure that the insurance cover is extended up to and includ-
ing the new Completion Date.
(iii) If the required All Risks Insurance cannot be obtained, prior
to executing the Contract, the parties should either amend
the definition of All Risks Insurance to accord with the cover
which can be obtained or state the risks which are to be
covered by the insurance in the Contract.
.2 Employer must approve the insurers with whom the contractor
takes out the Joint Names Policy under Clause 22A.1. Contractor
to send to the Architect, for deposit with the Employer:
(a) the Policy,
(b) the premium receipt for the Policy,
(c) any endorsements necessary to maintain the Policy, as
required by Clause 22A.1, and

63
64 Clause 22A

(d) premium receipts for any such endorsements.

If the Contractor defaults in taking out and maintaining the
insurance required under Clauses 22A.1 and 22A.2, the Employer
may:
(a) effect insurance by a Joint Names Policy against any risks
regarding which the Contractor’s default occurred,
(b) recover the premium amounts (paid or payable by the
Employer to effect the necessary insurance) from the Con-
tractor:
(i) by deduction from payments to the Contractor under this
Contract, or
(ii) as a debt of the Contractor.
Note: Any amounts paid by the Employer to effect insurance under
the Contract in the event of the Contractor’s failure to effect the
required insurance can be recovered from the Contractor either as
a debt (so, ultimately, by litigation) or by set-off, etc., against
monies due from the Employer to the Contractor under this con-
tract; under JCT 80 such sums cannot be transferred from one
project between the parties to another project. The usual means
of recovering such sums is by contra-charge or set-off against
monies due under Interim Certificates issued subsequently; set-off
is a common law right.
22A.3.1 If the contractor maintains a Contractor’s all risks insurance
independently, such insurance will discharge the Contractor’s
obligations to insure under Clause 22A.1 provided that:
(a) the scope of the cover is at least that required by Clause
22.2,
(b) the amount of cover is adequate for the Work’s full rein-
statement value plus any percentage for professional fees
(as Clause 22A.1), and
(c) it is a Joint Names Policy in respect of the Works.
The annual renewal date of such Contractor’s all risks
policy must be supplied by the Contractor and stated in the
Appendix.
The Contractor is not required to deposit such policy and
premium receipts with the Employer provided that, when rea-
sonably required to do so by the Employer, the Contractor
can send documentary evidence that the policy is being
Clause 22A 65

maintained to the Architect for inspection by the Employer.

Further, such inspection arrangements can be invoked by the
Employer on any occasion in respect of the policy and
premium receipts.
22A.3.2 The provisions of Clause 22A.2 (set-off, etc.) apply in respect
of the Employer’s rights to insure should the Contractor
default in respect of taking out and maintaining the insurance
required under Clause 22A.3.1 (contractor’s annual all risks
insurance).
22A.4.1 If any loss or damage which is covered by the insurance under
Clauses 22A.1, 22A.2 or 22A.3 occurs, immediately upon dis-
covering the loss or damage the Contractor must give written
notice to the Employer and to the Architect stating the
nature, extent and location of such loss or damage.
.2 The occurrence of such loss or damage must be ignored in
calculating amounts payable to the Contractor under or due
to the Contract.
.3 The Contractor must reinstate work damaged, replace or
repair Site Materials which have been lost or damaged,
remove and dispose of any debris and proceed with the
proper execution and completion of the Works once any
inspection required by the insurers regarding a claim made
under the Joint Names policy under Clauses 22A.1, 22A.2 or
22A.3 has been completed. Again, the Contractor is required
to work diligently to effect the repairs, etc.
.4 The Contractor must authorise the insurers to pay to the
Employer all monies from the insurance under Clauses 22A.1,
22A.2 or 22A.3 regarding loss or damage. The authority is in
respect of the Contractor and all those Domestic Sub-
Contractors and NSCs who, under Clause 22.3, are recognised
as insured under the Joint Names Policy. Those monies (less any
element for professional fees) must be paid to the Contractor
by the Employer as authorised by interim Certificate issued by
the Architect (but not the provisions of Clause 22A.4.5).
.5 The only monies which the Contractor is entitled to receive
in respect of the repairs etc. are those paid under the insur-
ance. Thus, the Contractor must bear any costs incurred in
excess of those monies paid under the insurance in the ex-
ecution of the repairs, etc. (Any Variation, however, would be
valued by the appropriate method and the Contract Sum
adjusted accordingly.)
