2.1         GENERAL
In this section of the PQAM, basic quality related concepts are defined and their interrelations
are briefed so that all of the supervisory staff has a minimum understanding of the need for
consistently defined quality management system as well as relevant terms. The section briefly
covers terms and interrelations of quality related terms such as Quality Assurance, Quality
Control, Process Control, Product Control, Attitudes, etc.
As quality is a broader issue to be satisfactorily covered by such a manual, the Resident
Engineer shall brief additional information to the supervisory staff upon the mobilization of each
staff.
2.2         TERMINOLOGY
                  2.2.1        QUALITY
Degree to which a set of inherent characteristics fulfills requirement /ISO 9000:2005/. Other
definition to quality includes:
“Fitness for purpose”/Juran/
“Conformance to specification or requirement”/Deming/
"Whilst perfection in any product is desirable, it is unattainable because the nearer one gets to
perfection, the greater the likely cost.
Therefore, quality is concerned with defining the levels of acceptable imperfection or tolerances
and assuring the minimum standards are achieved"
                  2.2.2QUALITY MANAGEMENT AND QUALITY MANAGEMENT SYSTEM
ISO 9000:2005 defines quality management as “coordinated activities to direct and control an
organization with regard to quality.” Whereas, quality management system is a management
system to direct and control an organization with regard to quality.
             2.2.3    QUALITY CONTROL
ISO 9000:2005 defines quality control (QC) as “part of quality management focused on fulfilling
quality requirements.” It involves both process monitoring and eliminating the causes of
unsatisfactory performance at all stages focused on fulfilling product requirements.
ISO 9000:2005 defines quality assurance (QA) as “part of quality management focused on
providing confidence that quality requirements will be fulfilled”
                              2.2.5 ACCEPTANCE
     Construction acceptance criteria for materials qualifications, inspection, and testing are
     established by technical specifications. Criteria for materials and equipment are set by the
     Engineer of Record in accordance with the applicable codes and standards.
Quality Control, on the other hand, is the controlling that is made during the implementation
process to ensure that every work item is delivered to the predetermined QA system. Hence, all
the project staff is supposed to make the required Quality Control at every stage of the works
based on the preset PQAM.
PQAM at the earliest time possible. The Material Engineer, who is part of the QA Panel for the
project, is responsible for evaluating such proposed revisions and brings the proposal to the
attention of the QA Team Leader. If the revision does not need the involvement of the QA Team
Leader, the Material Engineer shall make a suitable revision and issue a copy to the Resident
Engineer and the QA Team Leader for future incorporation into the next revision of the PQAM.
A separate folder shall be made avail for containing such proposed revisions.
It is also common for most Contractors to use lower compaction moisture and employ higher
but detrimental compaction level. Here the argument will be: “As far as the Contractor achieves
the desired level of compaction, what is the problem with lower water?” This is also related to
the attainment of the product without attaining the process. In case an inspector may not be
aware of the detrimental effects of over-compaction with lower moisture content, he may simply
allow such requests.
The Resident Engineer shall therefore enforce proper process control. In the course of process
control, the significance of each specification shall be made clear for each inspection staff by
the Material Engineer.
the absolute minimum for any one test is 96% for a certain layer work. The former criterion in
this case is a block failure criterion whereas the later one is a point failure criterion.
The following terms shall have the following definitions when used in this PQAM:
                       that may be referenced from 0.0 m from left or right of one of the carriage
                       way, via 5.25m at the centerline to 10.50m at right or left. When the
                       inspector uses his random number function (or he reads from random
                       number table on AASHTO or just from excel spreadsheet) before getting
                       out to site, let he get 0.173, 0.842, 0.431, 0.650 and 0.915. Hence, the
                       testing random points from the left edge of the road may be considered
                       as (test point = 10.50 m * random value) which is at 1.8m, 8.84m, 4.5m,
                       6.8m and 9.6m the left edge (or 2.3m LHS, 2.4m RHS, 0.5m LHS, 1.1m
                       RHS and 2.9m RHS from the centerline) from respectively for the stated
                       consecutive stations.
Reliability : Reliability or Level of Confidence is the desired result of a certain job. For
            instance, if the reliability desired for the characteristic strength of concrete is 95%,
            19 of the twenty specimens tested are required to satisfy the characteristic strength.
            However, as making 20 tests may not usually be viable, the characteristic strength
            of a certain lot is computed by employing statistical procedures, usually normal
            distribution.

       make sure that all his testing equipments are calibrated periodically at agreed / required
       intervals during the tenure of the project.
(v)    The Contractor shall collect all raw and processed samples of all materials jointly with the
       Engineer/Engineer are Representative for testing & seek approval of the Engineer prior to their
       use.
(vi)   The Contractor responsible to take precautions for safeguarding the environment and social
       aspects. He should keep all his machinery and equipment in good working condition and get
       them periodically checked to control the pollution.
(vii) The Contractor must prepare a traffic management plan to maintain smooth traffic flow during
      the construction stage. He should make all arrangements for traffic by maintaining the existing
      roads, constructing suitable diversion, if necessary.
(viii) The Contractor should satisfy that the site data furnished by the Employer’s Representative is
       in order, and in case of any discrepancy, he should get it corrected through the Engineer.
(xi)   The Contractor should establish the benchmarks in the field, both control and working
       benchmarks. It will be mandatory for the Contractor to establish separate benchmarks near all
       minor and major bridges/structures locations and should properly maintain these level pillars
       and periodically check the levels at least once in three months.
(x)    The Contractor should mark the centerline of the road in the field accurately and erect pegs at
       every 20 m interval in straight portion and in 10 m intervals in curves. At a regular interval, Toe
       line Pegs should be maintain inscribing the distance from the centerline and check them for
       correctness periodically. If they are going to be buried in the formation, he should establish the
       pegs afresh, and then accurately replace marking pegs as and when found necessary.
       Contractor should also establish reference control points beyond the outer limits of formations.
       The chainage boards are also to be established along with the marker pegs near the fence
       line/outside the formation limits. Whenever the centerline pegs are replaced due to exigencies
       of construction works, the same are to be got checked through the control points established
       outside the formation area.
 Earthworks – removal of unsuitable material, cut to fill, borrow to fill, select fill, capping layer
 Prime coat
 Tack Coat
 Asphalt Surfacing
 Any other work for smooth working such as Coordinating with respective service
provider/authorities, cutting trees, shifting of utilities and removal of encroachments.
In general, the contractor’s activities are executed in three stages
     Pre-construction stage
     Post-Construction stage
Pre-construction Stage
Detailed preparations are necessary before undertaking any construction activity. Their nature
will vary from work to work, location to location, project to project. However, they can be broadly
classified into the following categories
Setting out
This setting out of road centerline, excavation plan for structures is to be carried out in advance
and as per the guidelines given in the drawings and specifications. The setting out will include
establishment of benchmarks, centerline pegs, marker/reference pillars, by using precision
instruments like Total Station.
Procurement of materials, Storage and testing
This should be done well in time to ensure that quarries are identified and approved, suppliers
and manufacturers are identified and then manufacturing processes are got approved, test
results of all materials are available well before the activity is taken up and mobilization of other
resources is not aborted, if test results are not satisfactory.
Mobilizing and checking serviceability of equipment and machineries
Construction equipment and machineries such as concrete batch plants, pug mills, pavers,
rollers, dozers, excavators, vibrators etc. required for the work must be mobilized, their
serviceability checked and maintenance done before any work is commenced.
Quality Control aids and instruments
Quality control laboratory equipment’s are checked for their serviceability. The aids like cube
moulds, soil testing equipment’s ( proctor moulds with all accessories etc.), aggregate testing
equipment’s etc., camber boards, survey equipment’s are available in required numbers and in
good working conditions before the work is taken up.
Pre-construction checks
Pre-construction checks like checking formwork, reinforcement etc. must be completed before
commencement of work.
Pre-construction activities are absolutely vital for achieving quality, dimensional control and
should not be neglected.
Right of Way (ROW)
New Road construction work for the Access to Mekelle Industrial Park Design and Build Road
Project shall require the:
-       Land acquisition requirement
-       Details of properties affected
-       Status of payment of Compensation
Consultant’s ROW management specialist and ERA ROW agent shall effectively ensure that
assessment of compensation in respect of crops, building and other properties within the ROW
is carried out and assist the employer in obtaining the necessary ROW clearance.
Construction Stage
In general these activities will vary with the type of work e.g. earthwork, Sub grade, GSB,
crushed stone base, bituminous work and structural concrete works. A suitable format for
“Request for Inspection (RFI)” has been developed and attached to this QAM. Chapter 9 gives
the method statements of major construction activities.
Post Construction Stage
These activities are carried out on completion of the construction activity. Some examples are
curing of concrete, barricading to pavement entry over freshly laid concrete surface/crushed
stone base/bituminous surfaces to prevent traffic damaging the freshly laid surfaces.

traffic to pass over the road without picking up or otherwise damaging the primed surface, the
road shall, where practicable, be opened to public traffic for a period of 3 days.
Before commencing with the actual construction of any Prime Coat, laying a trial section of not
less than 500sqm shall be demonstrated so that the equipment and processes that are
proposed to be used, will enable to construct the Prime Coat in accordance with the specified
requirements. The trail section(s) shall be laid where indicated by the Engineer. Only when
such a trial section has been satisfactorily laid and finished, and complies with the specified
requirements, the actual permanent work shall commence.The Tack coatmaterial shall be RC-
70 cutback bitumen complying with AASHTO M81.RC-70 cutback Bitumen shall conform to the
requirements given in Table 4-20.

Note: (1) The use of the spot test is optional. When it is specified, the Engineer shall indicate
whether the standard naphtha solvent, the naphtha-xylene solvent, or the heptane-xylene
solvent will be used in determining compliance with the requirement, and also, in the case of
the xylene solvents, the percentage of xylene to be used.
Sampling and testing of bitumen shall be in accordance with the following standard method of
the AASHTO:

             4.5.5     PROCESS
No longer than 4 hours before spraying, the layer to be primed shall be broomed and cleaned
of all loose or deleterious material by means of a rotary broom and hand brooms.
Before any tack coat material is sprayed the layer to be primed shall be checked for compliance
with the surface and other requirements specified. Any sections not complying with the
specified requirements shall be corrected as specified in Division 6207.
Twine reinforced paper or other suitable approved material shall be used at all joints at the
beginning and end of all sprays in order to obtain a neat start and cut-off.
The temperatures for storage and spraying shall be in accordance with Table 4.5/6.

The rate of application shall be 0.4 Kg/m2 as directed by the Engineer after trial applications to
short sections as specified herein.
The Tack coat shall be applied in one or more lanes evenly over the full width of the road and
allowed to penetrate and cure until traffic can pass over the surface without the wheels picking
up the prime. All traffic shall be kept off the surface until this condition is obtained. The total
width of primed surface shall be 20cm outworks both sides of the edge of granular base/ sub
base course. If prime is applied in more than one lane, allowance shall be made for overlapping
the lanes by 100 mm.
Except for vehicles transporting materials for overlaying layer, no traffic shall be permitted on
the surface to be treated after it has been prepared to receive the bituminous material.

                    ii. Each fraction of the aggregate and binder shall be measured separately
                        and accurately in the proportion by mass in which they are to be mixed.
                    iii. Asphaltic mixes may be mixed and placed only under favorable weather
                        conditions, and shall not be mixed or placed when rain is imminent or
                        during misty or wet condition.
              iv. The mixture shall be transported from the mixing plant to the work in
                  truck complying with the requirement of technical specification sub-
                  clause 6406(c)
              v. The base course (after the prime coat has been applied) shall be
                  checked for smoothness and accuracy of grade, elevation and cross
                  section. Any portion, which does not comply with the specified
                  requirement, shall be corrected with asphaltic material, at contractors
                  own expense.
              vi. Notwithstanding these provisions for the correction of the base or sub
                  base, the engineer may order the removal and reconstruction of the layer
                  or of portions of the base and sub base layers not complying with the
                  specified requirements, instead of allowing the correction of substandard
                  work with asphaltic material.
             vii. Where a prime coat is applied it shall be dry before further coats or layers
                  are applied. The contractor shall not commence with the application of
                  the tack coat and/or the paving without the written approval of the
                  engineer.
             viii. The contractor's program shall allow for delays that are a function of the
                  type of prime, rate of application, base porosity and moisture content,
                  and climatic conditions.
              ix. Immediately before applying the tack coat, or where there is no tack coat,
                  before the application of the asphaltic layer, the surface shall be broomed
                  and cleaned of all loose or deleterious material. Where the prime coat (if
                  any) has been damaged, it shall be repaired by hand-brushing or
                  spraying priming material over the damaged portions. Where the
                  surfacing is to be constructed on bridge decks, the concrete deck shall
                  be thoroughly cleaned by washing and brushing to remove all loose
                  material and allowed to dry.
              x. All joints between adjacent sections of the work shall be made by cutting
                  back the layer against which the material is to be placed except for open-
                  graded asphalt where the requirements of clause 6407 shall apply. All
                  loose and incompletely compacted material shall be removed. A cutting
                  wheel shall be used for cutting longitudinal joints.
              xi. The mixture shall be delivered to the paver in such a manner that the
                  paver will never be forced to stop for lack of asphalt. The temperature of
                  the mix shall be controlled by measuring in a random pattern. The
                        adjustment of the screed, tamping bars, feed screws, hopper feed, etc.,
                        shall be checked frequently to ensure spreading of the mix.
                   xii. Compaction shall be applied according to the project technical
                        specification 6411.

                  4.9.3        MATERIALS:
The general requirements of material as specified in the Method Statement In-situ RCC
Box/Bridge shall be followed. The maximum size of aggregate for all precast concrete pipes
shall be 20 mm and minimum 28-day cylindrical compressive strength shall be 24 Mpa as
specified in the drawings.
The methodology for form work given in the Method Statement In-situ RCC Box/Bridge shall be
followed.
The following table shows the handling precautions (Do’s & don’t)
2 Cement Bag Fork lift/ Man power Do not wet or puncture the bags.
All the supervisory staff shall be well aware that poorly presented reports may possibly spoil the
whole job and are problematic for the review by a third party. After all, what remains as
permanent records of the project are the reports regardless of the thoroughness of the
investigation or analyses? Hence, the RE/ARE shall give adequate emphasis towards ensuring
the consistent and standard reporting by themselves and the remaining staff.
Hence, the QA Panel has hereby formulated standard reporting guidelines and standard
document formatting along with this PQAM as presented in the following sections.
As a rule of report preparation, all site staff shall be well informed regarding the following
standard report writing guidelines
          Before preparing any report, the outline shall be defined in the form of table of
          contents. This will ensure complete coverage of all desired elements as well as
          avoids redundant topics or ideas.
          To make the reports coherent with their headings, the sub-headings under any
          heading shall be clearly listed just before the start of the first sub-heading.
          All reports shall have Table of Contents, List of Figures and List of Tables similar to
          this PQAM. The “formal” style shall be used from the “Insert=>Reference=>Index
          and Tables=>format dropdown list box”.
          The RE shall ensure that all reports are checked by a sufficient number of relevant
          personnel
          The RE shall ensure that the Employer will be the sole owner of all reports and
          documents pertaining to the project
                  o    A4 size, top aligned, section starts with a new page, All margins to be 1”
                       except right margin that is 0.8”, Header=0.45”, Footer =0.45”
             The normal style1 of anybody text defined as the default paragraph style in the tools
             menu => option dialog box => edit tab => default paragraph style:
o Font : Arial 11
             Headings:
                  o    Style from heading 1 to 6: 1; 1.1; 1.1.1; 1.1.1.1; A/B and i/ii respectively
                  o    Paragraph and font formatting: As per the “Normal Template” in the template
                       folder.
             Header and Footer shall be in the format of this document. These annotations are
             directly connected to the document property inserted in the properties dialog box of
             the file menu. Direct typing in the header/footer view is not a standard practice and
             hence the RE and the QAE shall ensure such a practice. Please note that the center
             and right header/footer are in a frame so that they will automatically respond for
             changes in paper size or landscape orientation.
             Margins not to be manually adjusted: The minimum margins left on the right and
             left shall not be reduced by adjusting the ruler. If some items like wide tables are
             difficult to be contained in an A4 size portrait document, the paper orientation and/or
             the paper size would rather be adjusted.
             Number outlining shall be as per the stale named “(outline). All styles bound by
             parenthesis [i.e., ()], are user defined. Such a habit is encouraged among supervisory
             staff to make the user-defined ones sorted at the top as well as to easily distinguish
             user defined styles against built-in ones.
All other important items are well defined in the normal document template in the form of
electronic copy and the Material Engineer (who is also the QA representative for the Project) is
well aware of detailed standard documents desired by the firm.
The following document styles are specifically designed to be employed for the project and all
staffs are required to employ such consistent styles.

All the computers being used are loaded with the above mentioned electronic templates. To
ensure security of templates, however, the files are also issued to the RE in one read only
compact disk. All Microsoft Template Files are read only by default and can be found at the
“New Documents” shortcut.
Upon the delivery of each computer, the QAE shall ensure that all the computers are loaded
with such standard templates and other suitable forms.
          Relevance of records
          Manageability of records
Proper record keeping encompasses the following major items which are defined for the project
in the subsequent sections:
    1. Summary of Registers
    2. Administration
    3. Standard Forms (unfilled)
    4. Preliminaries
    5. Earthworks
    6. Unbound Pavements
    7. Bituminous Works
    8. Concrete, Minor Drainage and Slope Protection Works
    9. Bridges
           To allow easy follow-up of correspondences and memos by the RE and other staff
           To quickly find any record;
The QAE, the RE and the ARE shall thus ensure that summary of records are properly held in
the following three forms:
   1. Summary of each folder, hand field: on the top of each folder, an empty summary
       form shall be attached so as the secretary will fill it in a chronological order.
   2. Summary Book of Correspondences and Other Records: Other records such as all
       correspondences shall be filled on these books when such correspondences reach the
       project secretary. Summary book of drawing register and memo register shall also kept
       in the same way.
   3. Database of All Registers: The soft copies of the summaries of all records on the
       preset templates (in Ms Access or Ms Excel Format). Although Ms Access is a standard
       application for all such records, Ms Excel Equivalent templates are prepared as some
       project staff may not properly manage Ms Access database files.
Project staff shall communicate with special memos which are suitably referenced. The
referencing shall be in such a way that each staff ensures sequential memo numbering starting
1 like Memo # RE/07 to mean the seventh memo written by the RE. The RE shall also ensure
proper registry of all memos on the Memo Registry Template.
 All intermittent staff who has traveled to site shall write a memo to the RE upon the completion
 of each trip. Such memos shall include the dates, all jobs performed and any findings during the
 period.
 The basis of a good filing system is that someone from outside should be able to locate a
 specific item quickly and easily. Simply filing every piece of information in date order will
 quickly become unwieldy in all but small projects of short duration.
All project files shall be kept in a minimum two folders that include:
 Files by Category (Folder No 1 through folder No 15) as Listed under Section 5.3.4.1.
 The originals shall be put in the “files by date order” folders while the copies shall be placed in
 the “files by category” folders.

This format can be tailored to suit the specific project, but the basic numbering system should
be adhered to. The numbering system shall be clearly posted on the walls of the relevant
offices.
   1. Must be Accessed (Unsecured) Files: that should always be exposed for all the
       Employer Representative’s staffs. These files include all templates, database files and
       standard forms.
   2. Less Secured Files: that shall be accessed by only the relevant personnel
   3. Highly Secured Files/Folders: that shall not be exposed to others. The QAE shall ensure
       such security mechanisms for the project staff
Administrator rights, permanent user rights and guest user rights shall be defined by the QAE
for all the desktop as well as lap top computers assigned for the project.
           Folder No 16 (Chronological Order of Files) shall be put in a different place than the
           others to avoid risk of complete loss of files during fire hazards;
           Upon the delivery of each computer the hard disk shall be divided into the following
           folders:
                     Disks C, D and E as local disks/ built-in folders
                     Disks F and G as removable CD Drives (and Disk A as Floppy Disk Drive)
           All user files shall be stored under the Default “My Documents” folder. This folder
           shall be divided into at least the following folders:
                     “By Person” (All the supervisory staffs shall have separate folders on each
                      computes for their personal files)
                     “By Type” (subfolders include pictures, databases, etc) folder to store
                      software related files such as “help files”, “software manuals”, etc
                     “Letters and Memo” for correspondences
                     “Shared Files” folder to expose some files
                     File Registry folder (to include summary of correspondences, summary of
                      drawings, road strip charts, etc)
                     Other folders such as “Reports”, “Standard Forms”, “Personal”, “Other
                      Project Information”
           Disk D shall always be available for big standard manuals like Design Manuals,
           Road Network Studies, River Basin Studies, Other GIS Data, Pavement
           Management Data, e-books,
           Disk F shall be used for some risky applications such as downloaded programs. This
           is made to format the whole Disk F during possible virus of such risky files without
           affecting the most important local disks (C and D)
           A backup removable disk which fits the USB port shall always be available with a
           minimum capacity of 100 Giga Bytes.
           Backup of all electronic files in anyone of the computers shall always be ensured by
           the QAE at the end of each month on the first Saturday at 6:00 p.m.
           Backup of all working folders (“My documents” folder) in all computers shall be made
           at the end of each week on Saturdays at 7:00 p.m
           Virus scanning shall be made on a weekly basis just after the backup process while
           the staffs are out of work.
           All final reports shall be in “Read-Only “with random passwords technique. Such
           final reports shall also be copied to the project removable CDs on a monthly basis
           (same date as computer data backups). Important records shall also be converted
           and stored in Adobe Acrobat format with Acrobat 9.0, Professional Edition.

The quality control of the works shall generally be in accordance with the Works Contract.
However, it is not uncommon that most contract documents are not sufficient by themselves as
they contain discrepancies, deficiency and errors. It is also a generally understood fact that
contract documents (especially technical specifications and drawings) are not generally
complete by themselves. In such cases, the Engineer shall use proven yet suitable engineering
standards and sound engineering practices.
The Employer Representative’s approach towards quality control shall generally follow the
following tasks:
           Upon the mobilization of each staff, a briefing shall be made about the main aspects
           of this PQAM and the RE shall ensure that the staff has properly studied this
           document
           Proper design works shall be made in about 10 to 15 Km road stretches quite in
           advance of the contractor’s work program. The following sequences shall be
           followed:
              1.1   The Resident Engineer shall program the stretches to be designed based on
                    the employer’s requirement and Contractor’s work schedule;
              1.2   The Material Engineer (and if necessary the Geotechnical Engineer) shall
                    thoroughly revise all factual data pertaining to sub grade soil, land slide and
                    existing pavement. As necessary, the necessary laboratory tests shall be
                    made to revise the existing test results. Based on the test results and locally
                    available construction material, the ME may propose a different type of
                    pavement structure (different composition and/or thickness);
              1.3   In the meantime, detailed topographic surveying shall be made in any one
                    section quite in advance of the design to be made for 9km and 9.37km road
                    sections. The Senior Surveyor shall present the changes in the centerline
                    levels from the original design;
              1.4   The Highway Engineer and Structural Engineer shall also make the
                    necessary field assessment (plan-in-hand field inspection type) and take all
                    the necessary inputs for the revision of design and quantities;
              1.5   The ME, HE and SE shall forward to the RE office memos regarding their
                    findings and recommendations. The RE, ARE, ME, HE and SE shall arrange
                    a meeting to discuss and finalize design review issues;
              1.6   The HE and SE shall make the agreed design changes and submit for the
                    RE’s approval. The changes in design shall be accompanied by the
                    changes in quantities and associated changes in contract Duration if any.
                    Subsequent revisions may also be made to optimize the time of completion.
           The contractor shall be issued with the revised changes in design and he shall
           prepare and submit the template drawings.
           Sources of all materials proposed by the contractor shall be evaluated as per the
           procedures of “Materials Source Approval” which is dealt in this document
           Once the sources are approved, materials quality tests shall be made based on
           predetermined frequencies. The Material Inspector shall also periodically inspect all
           quarries and pits
           Process and product control shall be made as per:
              1.7   Common Guidelines for Most Work Items
              1.8   Inspection and Test Plan (Section 6.2)
              1.9   Standard Checklists for Monitoring Major Work Items (Section 6.1)
           Reporting as per Section 5
           Documentation and Record Keeping as per Section 5.3
To achieve proper QC, the Engineer shall also guarantee that the Contractor‘s attitude towards
quality shall generally be positive. To this end, those contractor’s managerial staffs and
foremen shall be given a brief clarification by the engineer upon their arrival. The necessary
actions shall also be taken on those staff those deliberately violet general ethical and moral
standards towards quality control to an extent of removing such individuals from the project.

request of the Contractor and/or the Employer Representative. Exhaustively done field trials will thus
ascertain quality, consistency and progress.
For layer works, trial-paving sections of 50 to 200 meters long shall be ensured. The layer works for
this project include roadbed preparation, embankment fill, unbound pavement layers (Road bases
and sub bases), prime Coat, Asphalt Binder Course, Tack coat and Asphalt wearing course.
Field trials will only be made after the approval of the sources of materials and method statements.
Upon approval of the sources, field trials shall be made to obtain suitable working methods and/or to
check the performance of the materials. Heavy moisture can be simulated by artificial showering on
the trial paved section with a suitable amount of water by using water truck.
Field trials may also be made for those materials which are considered to be marginal. This may be
achieved by paving the material for a short section and exposing it to traffic or heavy moisture for
longer period to monitor its performance against loading, wearing and moisture.
Among the items to be checked for the field trials of such layer works include:
           Achievement of suitable application rate of prime and tack coats for the Asphalt Concrete
           Binder Course and Asphalt concrete wearing course
           Achievement of job mix formula (JMF) for the asphalt concrete Binder course and asphalt
           concrete wearing course.
           Achievement of suitable compaction moisture content for compaction (as compared to
           OMC).
           To check the quality of materials after compaction.
           Adequacy of thorough mixing to achieve uniform moisture content.
           Adequacy of thorough mixing to avoid segregation.
           Determination of the required equipment to achieve a certain production.
           Number of passes and rolling patterns with different types of rollers to attain the required
           but not excessive (sometimes detrimental) level of compaction.
           To check the Contractor’s achievement of levels, lines and grades within the geometric
           tolerances.
During exhaustive field trials of unbound layer works, the use of nuclear gauges is recommended to
be very important as it is very simple and fast to repeatedly test the amount and uniformity of
moisture content during showering as well as to test dry density after each pass of rollers. The
achievement of the amount and uniformity will be determined based on the average and standard
deviation values respectively.
The trial sections, which are made exhaustively in such a way, will be the basis for subsequent
methods of working. Additional field trials may also be made in the course of construction for the sake
of economy, safety or serviceability based on the request of the Employer Representative or the
Contractor.
           Stock piling
           Showering
           Compaction (including desired lift thickness, etc.)
An ITP is prepared for the various components of the work by itemizing each component that requires
checking by the supervisory staff of both the Contractor and the Employer Representative. These
items are to be jointly agreed before work commences. Each ITP has a unique number for each
aspect of works. The format for ITP for all major items is enclosed in this PQAM.
Along with the ITPs, a procedure for inspection, testing and documentation of works in
progress/completed works has been prepared.
           Instructions for inspections, defining what is to be inspected, how and when inspections
           are made and inspection acceptance criteria.
           Contractor or Employer Representative to establish “Hold Points.” A “Hold Point” is
           defined as a part of the works that cannot proceed until it has been inspected and certified
           by signature of the proper authority. Hold points can be either Contractor “Hold Points”,
           requiring the contractor QC Manager’s signature or the Employer Representative “Hold
           Points” requiring signature by the Engineer or his designated representative. The format of
           the “Hold Point” will include, a description of the work to be inspected, appropriate pay
           item reference and shall be approved by the Employer Representative.
           Documentation of inspections on the “daily QC Report”
The IR books provide the means for the Contractor to inform the Employer Representatives, the
Laboratory and the Survey team that an activity requires checking, testing or surveying. The form will
indicate the location, time and type of activity.
       The foundation concrete of a box culvert is to be cast. The Contractor will make necessary
       entry in the IRB the previous day and submit to the Employer Representatives for inspection
       before casting. The Contractor’s Representative at site will have the “Pre-concrete inspection”
       form duly signed by him in token of having checked all the requirements. The Employer
       Representative’s Representative will carry out his own checks and sign the inspection form if
       all aspects are acceptable. If there are minor rectifications required, he will wait for it to be
       corrected before signing. He takes this form to the office and signs the relevant IRB entry.
       The IRB entry includes a column where the Contractor informs the Laboratory that slump test
       and cubes are required. The Laboratory Manager will sign in the column of IRB that he has
       received the LTR (Laboratory Test Request).
       Similarly the surveyor will be informed via the IRB entry when he is required for setting out of
       the Box Culvert. He comes with all relevant setting out data and he also has a form that he will
       sign which will be countersigned by the Employer Representative’s Representative after
       checking before entry in the IRB is closed. For checking of layer works, the site engineer will
       have design levels/dip levels as per approved drawings.
       By this method, the Contractor is making written commitment that his supervision have made
       their own inspection. As the job progresses the Employer Representatives will be able to
       assess the level of confidence in each team and be able to change “Hold Points” to “Witness
       Points”.
       If an inspection proves the work to be unacceptable, it will not be signed off in the IRB. The
       comment column of IRB will be completed as to why the work may not proceed. Work
       Inspection Record (WIR) will be created.
A new IRB entry must therefore be made for re-submission and to start the work. The original entry,
say 1007 will have an entry referring to the re-submission after rectification, say 1028.
These forms are to be carried out by the Supervision Employer Representatives on their visit to site,
make entries and sign. One sheet per each item of the work having the same unique number of IRB
will be maintained. These forms are also to be signed by the Contractor’s Supervisor.
An example is:
       A section of embankment is having the Moisture Content (MC) too high. It has not yet been
       submitted for approval. The Employer Representative notes it in WIR and gets the contractor
       to sign. Back in the office, the Employer Representative gets the IRB number and enters it on
       the WIR file. Similarly if it is observed that the survey beacons have been disturbed the same
       is noted in WIR.
       This is a record of inspection by the Employer Representatives. Necessary action will follow
       when the Contractor makes his request to have the work accepted.
The frequency, type and location of the tests are to be decided between the Material Engineer of the
Contractor and the Employer Representative in terms of the specifications.
REJECT – The action taken to eliminate a nonconforming item from its specified use.
       USE AS IT IS – The action taken to obtain the Employer Representative’s approval to accept
       otherwise unacceptable item.
Payment for work containing an uncorrected or unapproved non-conformance will not be approved.
The NCR is not a weapon to be used against the Contractor, but a statement of fact and an effective
method to ensure quality. Normally the Contractor would like to see as few NCRs as possible as any
re-work is costly and time consuming. The Employer Representative can use the NCR as a tool to
identify the people who cause the most NCR’s and can take action to have them trained or replaced.
A log to control NCRs from issue to closeout shall be maintained. All NCR’ corrected by “REPAIR” or
by “USE AS IT IS” shall be included in the “as-Built” document.
If on the course of the works, any more item is believed to be major the QAE shall prepare a similar
check list for that item.
