Today’s reality…
• Construction is complex and challenging.
• Delays, changes, disputes, accidents cost
more than ever.
• Construction contracts are among the most
complex forms of contract around because
determinations of satisfactory performance of
the obligation is difficult to determine.
3. 3
INTRODUCTION
A contract is a formalized means of
communication between two parties.
This facility is used very commonly by the
project manager and owner to control the
delivery of their projects.
A contract has the added advantage of forcing
owners to define their, requirements, organize
and arrange their thinking, and make a
commitment to their project.
4. BASIC REASONS FOR A CONTRACT
BASIC REASONS
1. It defines the work and the owner’s
delegation of responsibilities to the
various parties to complete the work
2. It inherently defines the nature and
extent of risk to various parties.
3. It defines the transfer of financial
incentives to complete the work.
5. CONTRACT
• THE WORD CONTRACT IS DERIVED
FROM LATIN WORD ‘CONTRACTUM’
WHICH MEANS DRAWN TOGETHER;
6. 6
WHAT IS A CONTRACT?
A contract may be defined as a voluntary
agreement enforceable at law, made between two
or more parties, whereby rights are acquired by
one party to act or forbearances by the other.
According to the Construction Specification
Institute (CSI) Manual of Practice, a contract is “a
promise or a set of promises for the breach of
which the law gives a remedy of the performance
of which the law recognizes a duty” (CSI 2008).
The agreement is reached by the acceptance of
an offer made by one party to do something for
other for a stipulated consideration.
7. 7
ELEMENTS OF A CONTRACT
These are the five basic elements of a contract
OFFER
CONSIDERATION
ACCEPTANCE
LEGAL PURPOSE
LEGAL CAPACITY
8. 8
CONTRACT AGREEMENT
The agreement is designed to formalize
the contract. It brings together all the other
contract documents by reference to them
and is legal instrument verifying the
contract.

CONTRACT MANAGEMENT
That function of a project which is responsible for
conformation of performance within the
stipulations of contract.
CONSTRUCTION CONTRACT
A contract under which one party promises to furnish
service & materials to build a structure for another party
who promises to pay for the work performed. There are
two basic types of construction contracts
Fixed price (or lump sum)
Cost type
10. 10
CONSTRUCTION CONTRACT
The success of a project is often judged on
the construction performance because this
activity is highly visible. The success of a
project is also influenced by;
The accuracy and details of its documentation
The understanding between parties and
acceptance of their particular responsibilities
How professionally and accurately the day to day
administration is handled
How conflict or contractual problems are
resolved.
11. Construction Project
Development Phases
Typical construction project development phases
includes;
1. Preliminary planning and feasibility studies
2. Preliminary engineering and design
3. Detailed Engineering design
4. Procurement
5. Construction
6. Operation
7. Demolition
12. Contracts are used during all phases of construction
projects.
In the first phase , which is the feasibility phase,
contracts are formed between an owner and a
consultant, an engineering firm, or an architectural
firm to perform a feasibility and site selection study.
In the construction phase contract are formed
between an owner and a Contractor firm.
13. Construction Contract Documents
Characteristics of a “good” contract document:
1. Carefully considered
2. Expressed clearly
3. Time-tested
4. Comprehensive
5. Fair
6. Balanced
7. Applicable to the elements of a construction

to as “addenda”
• owner must maintain a system of distributing and
acknowledging receipt of addendum
• plan and spec changes after award are referred to as
“revisions”, and generally require issuance of a Variation
order(s)
43. 51.1Variations
• The Engineer shall make any variation of the form, qualify or

ADMINISTER PROCUREMENT:
Claims Administration
Contested changes and potential constructive changes are those
requested changes where the buyer and seller cannot reach an
agreement on compensation for the change, or cannot agree that a
change has occurred.
These contested changes are variously called claims, disputes, or
appeals.
Claims are documented, processed, monitored, and managed
throughout the contract life cycle, usually in accordance with the
terms of the contract.
If the parties themselves do not resolve a claim, it may have to be
handled in accordance with alternative dispute resolution (ADR)
typically following procedures established in the Contract.
Settlement of all claims and dispute through negotiation is the
preferred method.
50. CONTRACT CLAIMS
• Contract Claims could occur at any stage in the execution of a
project.
• Typical causes of claims include:
• Differing site conditions
• Delays
• Design error or changes
• Interpretation differences
• Acceleration or suspension of work
• Additional work
• Deleted work
• Construction failures
51. Claims Avoidance
• producing comprehensive, accurate, contract
documents
• constructability review
• clear understanding of contract requirements prior to
bidding
• having good administrative procedures in place
• open and honest communication
• timely troubleshooting
• Claims avoidance begins in the pre-
construction phase
52. Procedure for Claims
53.1Notice of Claims
Notwithstanding any other provision of the Contract, if the Contractor intends to claim any additional
payment pursuant to any Clause of these Conditions or otherwise, he shall give notice of his intention to the
Engineer with a copy to the Employer, within 28 days after the event giving rise to the claim has first arisen.
53.2Contemporary Records
• Upon the happening of the event referred to in Sub-Clause 53.1, the Contractor shall keep such
contemporary records as may reasonably be necessary to support any claim he may subsequently wish to
make. Without necessarily admitting the Employer's liability, the Engineer shall, on receipt of a notice under
Sub-Clause 53.1, inspect such contemporary records and may instruct the Contractor to keep any further
contemporary records as are reasonable and may be material to the claim of which notice has been given.
The Contractor shall permit the Engineer to inspect all records kept pursuant to this Sub-Clause and shall
supply him with copies thereof as and when the Engineer so instructs.
53.3Substantiation of Claims
• Within 28 days, or such other reasonable time as may be agreed by the Engineer, of giving notice under
Sub-Clause 53.1, the Contractor shall send to the Engineer an account giving detailed particulars of the
amount claimed and the grounds upon which the claim is based. Where the event giving rise to the claim
has a continuing effect, such account shall be considered to be an interim account and the Contractor shall,
at such intervals as the Engineer may reasonably require, send further interim accounts giving the
accumulated amount of the claim and any further grounds upon which it is based. In cases where interim
accounts are sent to the Engineer, the Contractor shall send a final account within 28 days of the end of the
effects resulting from the event. The Contractor shall, if required by the Engineer so to do, copy to the
Employer all accounts sent to the Engineer pursuant to this Sub-Clause.
54. Settlement of Disputes
67.1 Engineer's Decision
If a dispute of any kind whatsoever arises between the Employer and the Contractor in connection
with, or arising out of, the Contract or the execution of the Works, whether during the execution of the
Works or after their completion and whether before or after repudiation or other termination of the
Contract, including any dispute as to any opinion, instruction, determination, certificate or valuation of
the Engineer, the matter in dispute shall, in the first place, be referred in writing to the Engineer, with
a copy to the other party. Such reference shall state that it is made pursuant to this Clause. No later
than the eighty-fourth day after the day on which he received such reference the Engineer shall give
notice of his decision to the Employer and the Contractor. Such decision shall state that it is made
pursuant to this Clause.
Unless the Contract has already been repudiated or terminated, the Contractor shall, in every case,
continue to proceed with the Works with all due diligence and the Contractor and the Employer shall
give effect forthwith to every such decision of the Engineer unless and until the same shall be
revised, as hereinafter provided, in an amicable settlement or an arbitral award.
• Amicable Settlement
Where notice of intention to commence arbitration as to a dispute has been given in accordance with
Sub-Clause 67.1, the parties shall attempt to settle such dispute amicably before the commencement
of arbitration. Provided that, unless the parties otherwise agree, arbitration may be commenced on or
after the fifty-sixth day after the day on which notice of intention to commence arbitration of such
dispute was given, even if no attempt at amicable settlement thereof has been made
56. 58
INCREASE OR DECREASE OF COST
• It is not in the best interest of the Employer
to ask tenderers to quote firm prices with
no provision of adjustments, especially for
long-term contracts.
• In bidding documents having provisions for
price adjustment, the Employer is expected
to receive more competitive offers from
reputable parties and will have to meet the
net variations in cost as may actually
occur.
59. 61
Why a formula?
• Make price adjustment (as a reasonable
compensation against variation in prices
of the selected materials and inputs) as
close as possible to the actual;
• Set out a simple procedure;
• Minimize ambiguities; and
• Make the contract more equitable.
60. 62
1.COMPLETION PERIOD OF THE
CONTRACT
Only contracts having duration of six months
or more should be liable to price adjustment.
2.COST OF THE CONTRACT
The Price Adjustment shall be applicable
only for the contracts having contract price
exceeding financial limit of PEC Contractors
Registration Category C-5 (Rs. 30 Million).
