CHAPTER 2 STANDARD PROCEDURES FOR PROCUREMENT
2.1 Introduction
When goods, works or services are procured, a clear procedure has to be followed to
minimize the errors and maximize the benefits. Over the years these procedures have
been evolved and Standard Procurement Procedures are available to provide
consistency to the process.
Application of Standard Procurement Procedures is necessary for a systematic
approach for tendering and awarding of contract for construction projects. It should
assist the Employer to receive sound competitive tenders in accordance with the
tender documents so that they can be assessed quickly and efficiently. At the same
time it should provide the opportunity and incentive to contractors to respond easily
^ to tender for projects which they are qualified to implement. It is expected that the
adoption of standard procurement procedures will minimize tendering costs and
ensure that all tenderers receive a fair and equal opportunity to submit their offers on
a reasonable and comparable basis.
In-the case of projects involving either international or local tendering (large and
complex in nature), prequalification is desirable, since it enables the employer to
establish the competence of companies subsequently invited to tender. It is also in
the interest of contractors, since, if prequalified, they will know that they are
competing with a limited number of other firms, all of whom possess the required
competence and capability.
A good standard procurement procedure should facilitate flexibility and alternative
courses of action that may have to be considered according to circumstances.

2.2 Available Standard Procurement Procedures
8
Apart from the Sri Lanka Government Financial Regulations (Ministry of Finance
1992), there are published standard tender procedures available for Client's use for
selecting contractors for construction projects. This research studied the following
standard procedures in detail so that these can be compared with the Sri Lanka
Government Financial Regulations.
1. Guidelines for Tender Procedures - Sri Lanka (ICTAD 1990)
2. FIDIC Tendering Procedure (FIDIC 1994)
3. Code of Procedure for Single Stage Selective Tendering (NJCC 1977)
4. Code of Procedure for Two Stage Selective Tendering (NJCC 1983)
It is not the intention of this report to provide a detailed description of the
procedures. The essence of the procedures have been considered when the standard
procedures were established as given in 2.3.
2.2.1 Guidelines for Tender Procedures - Sri Lanka (ICTAD 1990)
These guidelines have been prepared for the use of Employers who wish to procure
supplies and services through competitive tender procedures. Whilst safeguarding
the interests of the Employer, the procedures outlined also provide for an impartial
evaluation of the tenders so as to create confidence amongst the tenderers to enable
them to prepare realistic tenders. Though the guidelines are specially designed for
procedures to be adopted for large scale contracts, they could, however, be the basis
for procedures for small contracts too.
2.2.2 FIDIC Tendering Procedure (FIDIC 1994)
FIDIC is the International Federation of Consulting Engineers comprising of
National Associations whose members comply with FIDIC's code of Ethics.
The procedure is suitable for tendering for most international construction works, but
it may be adapted to suit the particular requirements occasioned by the size and
complexity of a. project, and any special condition imposed by the established
procedures of the employer or financing institutions. It reflects good current practice.
The procedure is related to FIDIC's "Conditions of Contract for works of Civil
Engineering Construction", but can be readily adapted to any acceptable contract
form.
FIDIC believes that the second edition provides a comprehensive and complete
procedure, compatible with other recognised tendering procedures, which will
encourage and enhance the ultimate objective of receiving responsive and
competitive tenders.
2.2.3 Code of Procedure for Single Stage Selective Tendering (NJCC 1977)
This code assumes the use of standard forms of building contract. The Contractor's
tender is the price for which he offers to carry out and complete, in accordance with
the conditions of the contract, the work shown on the drawings and described in the
bills of quantities and/or specifications.
This tendering procedure demands that the Contractor's Tendered Price should not be
altered without justification. The code lays down alternative methods of dealing with
errors or discrepancies between prices and the tender figures.
2.2.4 Code of Procedure for Two Stage Selective Tendering (NJCC 1983) /
This code assumes the use of a standard form of building contract, which would be
entered into, following the successful completion of the second stage procedures.
The purpose of this code is to set out procedures for the selection of a contractor by
means of a first stage competitive tender based on pricing documents related to
preliminary design information, and which provides a level of pricing for subsequent
negotiations, the production of a second stage tender by pricing, in accordance with
the first stage tender, bills of quantities reflecting the completed design.
2.3 Standard Procedures For Procurement
After a thorough study of the available procurement procedures the following six
stages have been identified as the necessary activities to formulate a standard
procurement procedure.
Stage 1 - Project Strategy
Stage 2 - Prequalification of Tenderers
Stage 3 - Obtaining Tenders
Stage 4 - Opening of Tenders
Stage 5 - Evaluation of Tenders
Stage 6 - Award of Contract
Under each stage the procedures given in the above procurement documents were
analysed and a common standard procedure was established.
10
2.3.1 Project Strategy
11
This involves Establishment of Procurement Method, Form of Tendering and
Preparation of Programmes.
Projects may be organized and implemented in accordance with different strategies.
A brief description of some of these is given in Table 1 .
Choosing the best strategy for a particular project depends on factors such as the
nature and complexity of the project, the access to finance, life cycle cost of the
project, the technical and administrative capability of the employer, the general
political and economic environment etc.
Primarily the procurement method depends on the client's requirement and the
Contractor's proposal.
The available procurement methods are
(a) Traditional Procurement System
(b) Design and Build Contracts (Package deal or Turnkey Contracts)
(c) Management Contracting
(d) Construction Management
When choosing the appropriate procurement methods, strengths and weaknesses
of both the client and the contractor to be assessed and the involvement of both
parties should be considered.

Reference : FIDIC Tendering Procedure 1992.
Some important criteria to be considered for the selection of best Procurement for
a particular project is given below :
(a) Client's involvement with the process of Construction
(b) Complexity of the Project
(c) Separation of design from management
(d) Reserving the client's rights to alter the specifications
(e) Speed from inception to completion
(f) Certainty of price
(g) Client's contractual remedies for defective work.
( Murdoch and Hughes, 1992)
Forms of Tendering are to be established by determining the following.
(i) The part of the project for which tenders are to be sought,
(ii) The conditions of contract to be adopted,
(iii) The award criteria,
(iv) The tendering procedure, and
(v) The criteria which shall be used to prequalify tenderers.
Normally a preliminary overall programme covering all major activities of the
project should be prepared at the initial stage of the project. It should comprise the
main phases of the project, ie.
Project definition
tendering procedure
design
construction
taking-over
In order to ensure this compliance, details programmes should be made with
durations and deadlines for each activity. That is;
13
Preparation of tender documents
Preparation of prequalification documents
Prequalification of tenderers
Obtaining tenders
opening of tenders
evaluation of tenders
award of contract
Time should be given in each programme for the employer to make necessary
decisions and give required approvals.
2.3.2 Prequalification of Tenderers
The aim of prequalification is to establish a list of capable firms whilst ensuring that
a proper level of competition is safeguarded.
Prequalification documents should normally include the following :
(a). Letter of invitation to prequalify,
(b). Information about the prequalification procedure,
(c). Project information and
(d). Prequalification application.
The prequalification application should contain;
Name and Address of the Employer,
Name and Address of the Engineer,
14
Location of the project,
Description of the project and scope of work included in the contract,
Anticipated program, including the tender period, contract award date,
designs/constructions/commissioning period and any other relevant key dates,
Conditions of Contract to be used,
Criteria for evaluation of tenders,
Criteria for prequalification,
Details of any work intended to be undertaken by nominated subcontractor(s),
Anticipated sources of finance (including any requirement for contractor
financing),
Payment arrangements envisaged (including currencies),
Any financial guarantees to be given by contractor,
Whether price escalation arrangement will be included,
Language and law of the contract,
Any aspect of the intended work which is unusual and would thus have a'
bearing on the contractor's obligations, and
Charges for purchase of tender documents, if applicable.
(FIDIC 1994)
Standard prequalification forms are available in FIDIC (1994) and ICTAD (1990).
The prequalification notice should be published in appropriate newspapers and
journals to give sufficient publicity according to the particular circumstances of the
project.
15
According to FIDIC (1994) evaluation of prequalification should consider the
following:
- Structure and organization of the company
- Experience in both the type of work and the country or region in which it is to
be undertaken.
Available resources, in terms of management capability, technical staff,
construction facilities, maintenance and training facilities, or other relevant
factors.
Quality assurance procedures and environmental policy
Extent to which any work would be likely to be subcontracted.
Financial stability and resources necessary to execute the project.
General suitability, taking into account any potential language difficulties
Litigation or arbitration history
If the resulting list, after excluding the unsuitable firms exceeds six potential
tenderers and there are no special regulations or conditions imposed on the employer,
the elimination starting from less qualified should be continued in order to arrive at
no more than six. (FIDIC 1994)
Selected tenderers should be notified and requested to confirm their intention to
submit a tender. (FIDIC 1994)
Instead of prequalification a short list of suitable contractors (Tenderers) could be
drawn up from the employers approved list of contractors or from an ad-hoc list of
contractors of established skill, integrity, responsibility and proven competence in
carrying out similar type of works.
16
The. number of tenderers to be invited should depend on the cost of the project. This
number varies from 5 to 8. Additional one or two should be added in order to replace
any tenderers who do not accept the preliminary invitation. (JNCC 1977).
Format of the invitation to tender and form of tender should be sent to the selected
.tenderers. The conditions of tendering should be absolutely clear so that all tenders
are submitted on the same basis. It is recommended to use the standard forms of
building contract-in uriammended form. (NJCC 1977)
Pre-qualification is normally advisable for large or complex contracts to ensure that
invitations to tender are confined to capable organizations. In the case of small scale
contracts, special pre-qualification procedure may not be necessary. In such cases
post qualification procedure may be adopted in order to ensure successful execution
and completion of the work.
For all types of contracts, tenders may be restricted to contractors who are registered
with government organizations or other institutions under the Scheme of National
Registration and Grading of Construction Contractors developed by Institute for
Construction Training and Development (ICTAD) for works of similar nature. The
Evaluation Report should be submitted within the shortest possible period. (ICTAD
1990)
2.3.3 Invitation to Tender and Obtaining Tenders
The tender documents which are prepared by the employer/engineer should normally
include the following:
Letter of invitation to tender,
Instructions to tenderers,
Tender forms and appendices,
17
Conditions of contract (Part I and II) together with any requisite
forms,
Specification,
Drawings,
Preamble to BOQ
Bill of quantities or schedule of prices,
Information data, and
List of additional information required from tenderers.
Letter of invitation to tender should include
Tender reference and title,
List of documents issued,
Receipt form for the tender documents (to be signed and returned by the
tenderers),
Instructions to inform the employer/engineer, in writing, of any significant
changes to the data supplied in the pre-qualification application, and
Date and place of tender submission and tender opening.
Tenderers should be informed of whether alternative tenders will be considered or
not. If a tender security is required, a form should be included in the tender
documents. It is recommended that the period of validity of the security (Bond) shall
equal the period of validity of the tender plus the time allowed for the tenderer to
provide his performance security under the terms of the eventual 'contract between
the contractor and the employer.
If a specific method of evaluation is to be used in selecting the successful tender, the
method should be described in the instructions to tenderers. (FIDIC 1994).
Tenders shall be submitted in duplicate (or in such number as the instructions to
the Tenders may indicated), on the approved Form of Tender. Each set of tender 18
C0c2g£ SeT R e l a t e s . § QoCeO
document should be enclosed in a separate envelope/package, sealed and
addressed to specified authority.
Tenders should normally close at the time and date specified in the tender notice
unless an extension of time has been granted by the Employer. Any tender
received later than the closing time should be rejected. Such rejected tenders shall
be returned unopened to the tenderers.
The tenderers or their representatives should be allowed to be present when the
tenders are open, and it should be so indicated in the Tender Notice or Instructions
to Tenderers.
Time allowed for the preparation of tenders should be determined in relation to the
size and complexity of the job.
Tenders submitted by each tenderer, should be based on identical tender documents.
If it is decided to amend the documents, the issuing authority or consultant should
inform all tenderers and extend the time for tendering if necessary (NJCC 1977).
Tenders are invited by publishing notices in the three languages in approved
Newspapers. The notice calling for tenders shall be of a standard form.
For major works or works of a specialized nature, tenders shall be invited only from
contractors pre-qualified for the project. Pre-qualified contractors will be invited in
writing to tender for the project. (ICTAD 1990)
2.3.4 Opening of Tenders
Date and time should be fixed for the official opening.
Check and display the sealed conditions of each tenderprior to its being opened.
As each tender envelope is opened, the following should be announced.
Tenderer's name
Tender price
Price of alternative tenders if appropriate
Tender security
Thereafter names of any tenderers disqualified should be announced with reasons.
Opening of tenders may be carried out in one of the following two ways which ever
is appropriate.
in public - The date, time and place of opening should be advertised in the press and notified to tenderers.
restricted - In the presence of those tenderers wishing to attend, all
having been informed of the date, time and place of the
opening. (FIDIC 1994)
Tenders should be opened as soon as possible after the time for receipt of tenders.
The lowest 3 tenderers should be asked to submit their priced BOQQ as soon as
possible and in any case within 4 working days in the case of two stage tendering .
All the others should be informed that their tenders have been unsuccessful. (JNCC
1977)
20
2.3.5 Evaluation of Tenders
A committee should be appointed by the Chairman of the Tender Board or by the
Specific Authority for the Evaluation of tenders received.
On large projects, the committee shall consist of not less than three persons
knowledgeable on the Works. On small works, the committee may be less than
three persons with at least one member having necessary technical knowledge. In
the case of small .works, the committee may even be a single individual.
If a Consultant for the project is available, copies of one set of tender documents
should be forwarded by the Chairman of the Tender Board or Specific Authority for
the Consultant's Evaluation Report. (ICTAD 1990)
Tenders should be checked to establish that they are arithmetically correct, are
responsive without errors and omissions and consistent with the invitation to tender.
Tenders containing deviations are dealt with as given in the instructions.
Generally, evaluation of tenders consists of the following three components;
Technical evaluation
Financial evaluation
General contractual and administrative evaluation
21
p
2.3.5.ITechnical Evaluation
22
Technical Evaluation may include
. conformity with specifications and drawings
comparison of any proposed alternatives (if allowable) with the
requirements of the tender documents,
design aspects for which the contractor is responsible
v - methods of construction and temporary works
environmental considerations
quality assurance
programme
(FIDIC 1994)
2.3.5.2Financial Evaluation
Financial Evaluation may include
capital cost
discounted cash flow and nett present value
programme of payments
currencies
Af - securities
interest rates
down payments/retentions
day work rates
contract price adjustment proposals
(FIDIC 1994)
2.3.5.3 General Contractual and Administrative Evaluation
23
General Contractual and Administrative Evaluation may include
conformity with instructions to tenderers
completeness of tenders
validity of tenders
exclusions and deviations - stated or implied
insurance
experience of proposed key staff
shipping, customs, transport, etc.
working hours
labour build-up, run-down and source
(FIDIC 1994)
2.3.5.4Rejection of Tenders
In the event of rejection of all tenders, the tenderers should be advised of the reason.
If new tenders are to be invited, the causes leading to the rejection should be
carefully reviewed.
Tenders should not be rejected and completely new tenders invited against the
original tender documents for the express purpose of obtaining lower prices.
Rejection of all tenderers is justified when
tenderers are not substantially responsive to the tender document
too few tenders are received to ensure competition. (FIDIC 1994)
If negotiation fails as indicated in 2.3.5.6
2.3.5.5 Correction of Tenders
Examination of priced BOQQ should be done by the Consultant or the Appointed
Committee. Any errors will be dealt with using the following two alternatives.
Alternative 1
The lowest Tenderer should be given details of such errors and afforded an
opportunity of confirming or withdrawing his offer. If the Tenderer withdraw, the
priced bill(s) of the second lowest should be examined, and if necessary this tenderer
be given a similar opportunity.
If the tenderer confirms the tender; an endorsement should be added to the priced
bill(s) indicating that all rates or prices (excluding preliminary items, contingencies,
prime cost and provisional sums) inserted therein by the Tenderer are to be
considered as reduced or increased in the same proportion as the corrected total of
priced items exceeds or falls short of such items. This endorsement should be signed
by both parties to the contract.
Alternative 2
The lowest Tenderer should be given an opportunity of confirming his offer or of
amending it to correct genuine errors. For this purpose, genuine errors are defined as;
(i) discrepancy between the amount in figures and in words (ii) discrepancy between
unit rates and line item total. Should he elect to amend his offer and the revised
tender is no longer the lowest, the offer of the firm now lowest in the competition
should be examined.
If the Tenderer elects not to amend his offer, an endorsement will be required as
earlier in Alternative 1. If the Tenderer does amend his tender figure, and possibly 24
certain of the rates, in his bill(s), he should either be allowed access to his original
tender to insert the correct details and to initial them or be required to confirm all the
alterations in a letter. If in the latter case his revised tender is eventually accepted,
the letter should be conjoined with the acceptance and the amended tender figure and
the rates in it substituted for those in the original tender.
2.3.5.6 Negotiated reduction of tender
If the tender price exceeds the employer's budget the recommended procedure is for
a price to be negotiated with the lowest qualified tenderer. The basis of negotiation
and any agreements made should be fully documented. If these negotiations fail then
the employer should proceed negotiations with the next lowest and then with the
third lowest. If all these negotiations fail, new tenders may be called for. (NJCC
1977)
2.3.6 Award of Contract
The Contract-should be awarded to the tenderer submitting the lowest evaluated
responsive tender and must be made during the period of tender validity or any
extension thereto accepted by the tenderers.
Before the signing of Agreements, the construction programme, variation of work
items or additional works necessary and such other details may be fully discussed
and understanding should be reached. Method of Construction, Construction
Programmes, Cash flow Statements and other details submitted by the successful
tenderer may need adjustments or amendments in order to meet the Employer's
requirements. These matters need to be fully discussed, negotiated and finalized
before formal acceptance of the tender. All Agreements reached on these matters
should be incorporated into a "Memorandum of Understanding" (MOU), and
included in the documents forming part of the Agreement. (ICTAD 1990)
25
The performance security should be furnished before the expiry of the validity period
of the tender.
Contract Agreement should include the following documents
Letter of Acceptance and M O U
Letter of Intent (If applicable)
The tender
Conditions of Contract
Specification
Drawings
B O Q
(FIDIC 1994)
and such other documents that are intended to form the contract.
Upon the furnishing of the performance security by the successful tenderer
Employer/Engineer should promptly notify the other tenderers in writing that their
tenders have been unsuccessful. At the same time arrangements have to be made to
return securities provided by the unsuccessful tenderers. (FIDIC 1994)
26
