CHAPTER 4 : TECHNICAL REPORT
VARIATION ORDER
4.1 Introduction
Variation Order (VO) is meant any additions, replacement, omission or
changes to the specifications, drawings or quantity on a contract or original
work. Any Variation (VO) can only be performed by the contractor in the
event of a formal directive issued by the Superintending Officer (SO).
- Variation to the original work is almost certain to happen in construction
projects due to :
a) Site conditions.
b) Statutory requirements.
c) Change in client‟s requirements.

30
d) Defective contract drawings, bills of quantities, specification, etc.
(including intentional abuse of variation clause since contract
allows changes to design, etc.)
e) Poor cost control e.g. omissions required due to shortage of fund.
- Most forms of contract have provisions which will allow any necessary
changes to be made during the construction process.
- Without the variation clause, changes to the original contract are not
allowed. If changes to the works are necessary :
a) Separate contract has to be drawn up (e.g. for additional work)
b) A new contract has to be prepared to replace the existing contract
(e.g. changes in design)
- For contract based on bills of quantities – the contractor has the right to
claim under variation for carrying out the works not provided for or
measured in the bill of quantities.
- For contract based on drawings and specifications – the contractor does
not have the right to claim under variation for carrying out all works
incidental or necessary for the completion of the work even though those
works are shown in the drawings and described in the specifications.

31
4.2 P.W.D Form 203A (Rev. 2007)

35
4.4 Procedure of Variations
Figure 4.4.1 – Variations Process
S.O. issues instruction to
contractor (Clause 24.1)
CONTRACTOR carries out
the work (Clause 24.1)
S.O. measures, values the certifies
work (Clause 25.1, 25.3)
EMPLOYER pays contractor through
interim payment (Clause 28.6)

36
4.5 Instructions for Variations
4.5.1 Power to Issue Instruction
„The S.O. may from time to time issue further drawings, details and/or
written instructions (All of which are hereafter collectively referred to as
“S.O.‟s instructions”) in regard to : (a) The Variation..‟ (Clause 5.1)
- The S.O. has the power to issue instructions to cover not only variations
but many other areas for proper execution of the work.
- Not every instruction constitutes a variation but every variation requires
an instruction. The contractor therefore cannot expect payment for every
work that he did in compliance with the instruction.
- The contractor may request the S.O. to specify the contract condition
which empowers him to issue instruction.
- Instruction given by any other person will not valid.
„…No variation required by the S.O shall vitiate this Contract...‟
(Clause 24.1)
- The S.O. has full power to issue instructions to the contractor to carry out
any variation work which he thinks necessary for satisfactory completion
of the project.
- Generally, any variation instructed by the S.O. is allowed under the
contract and it will not be in breach of contract.

37
- However changing the original scope of work is not allowed. The variation
should not fall outside the scope of works contemplated by the parties at
the time when the contract was made. The contract does not authorize
extra work not related to the original project.
- Omission of work is allowed under the contract (Sub-clause 25(b)(iii)).
The limitations are as follows :
a) Invalid omission – the S.O. may omit work only if it is not to be
done at all. The omitted work cannot be carried out by another
person. Galagher v. Hirsh (1899) – work was omitted and given to
another contractor was held to be a breach of contract.
b) Substantial omission – extensive omission that substantially
changes the character of the work will be a ground for claim for
breach of contract by the contractor.
4.5.2 Written Instructions
„All instructions issued by the S.O. shall be in writing. The Contractor
shall forthwith comply with all instructions issued to him by the S.O. If
such instruction is given orally, the S.O. shall then issue a written
instruction within seven (7) days from the date of such oral instruction
is given.‟ (Clause 5.2).
- An oral instruction is of no immediate effect and it does not bind the
contractor to comply with it.

38
Figure 4.5.2.1 – Comfirmation of Oral Instruction.
- Any oral instruction must be comfirmed later in writing within 7 days after
its issuance by the S.O. himself. The instruction only takes effect upon
confirmation.
- The contractor will have to bear the cost of complying to the oral
instruction if the S.O. does not confirm the oral instruction within 7 days –
the S.O. is not bound to do so.
„The S.O. may issue instructions requiring a Veration in a form of a
Variation Order..‟ (Clause 24.1).
- All instruction regarding variations issued by the S.O. must be in writing
and in a recognized format entitled Variation Order as shown in Figure
4.5.1.1.
- The particulars to be stated by the S.O. in the Variation order include :
a) Description of variation.
b) Estimated cost of variation.
c) Cumulative total value of variations to date.

forthwith comply with the Variation Order issued by the S.O.‟ (Clause
24.1)
„If within seven (7) days after receipt of the written notice from the S.O.
requiring compliance to an instruction and the Contractor does not
comply therewith, then the S.O. …undertake the work departmentally,
or employ and pay another contractor or any other persons to execute
any work…‟ (Clause 5.3)
- The contractor must comply with the S.O.‟s instruction immediately.
- If the contractor does not comply with the instruction, the S.O. will send a
notice to the contractor requiring the contractor to comply with the
instruction.
Figure 4.5.3.1 – Non-compliance to Instruction by Contractor.
- If the contractor still does not comply with the instruction within 7 days
after receiving the notice, the S.O. may take the following actions :
a) Execute the work departmentally.

employment (including On-Cost Charges), shall be deducted from any
money due or to become due to the Contractor under this Contract,
and failing which such deduction shall be recovered from the
Performance Bond or as a debt due from the Contractor..‟ (Clause 5.3)
- The payment made to the third party or the employer himself for
executing the work can be deducted from the contract sum, performance
guarantee sum, etc.
- The employer can also claim for on-cost charges – the cost and expenses
incurred by the employer in getting the work done by another contractor
or by the employer himself.
- The percentage for on-cost charges is fixed in the Appendix as 5% of the
cost of the affected work.
- If the contractor carries out the work that is outside the work he was
bound to do for original contract price without S.O.‟s instruction :

stated in the bills of quantities :
a) No instruction is required.
b) The contractor is bound to carry out works in excess of those
stated in the bills of quantities.

42
4.6 Measurement of variations
4.6.1 Generally
„All variations instructed in writing… shall be measured and valued by
the S.O….‟ (Clause 25.1)
- The S.O. is responsible to measure and value the variation works done by
the contractor.
- The measurement and valuation of the works should be done as soon as
possible to enable payment for the works to be included in the interim
payment certificates.
- The variation work which is to be treated as the work done by the
contractor has to be paid in the interim payment certificates even though
Certificate Of Adjustment Of Contract Sum is not yet prepared.
- The S.O. is only required to measure variations that have been confirmed
in writing.
- Method: Omit the work from the contract bills and add the measurement
of the work carried out as instructed.
„The S.O. … the works to be measured … give reasonable notice to
the Contractor who shall attend or send a qualified agent to assist the
S.O. … shall furnish all particulars required by the S.O.. Should the
Contractor fail to attend… the measurement made by the S.O. or
approved by him shall be taken the correct measurement of the work‟.
(Clause 27.1)

43
- The measurement of work will used for the valuation of variation.
- The measurement sometimes needs to be done on site especially when
the measurement cannot be accurately done based on the available
information or drawings.
- The S.O should carry out measurement of the variation work jointly with
the contractor.
- The S.O. will send a notice to the contractor informing him about the
measurement to be made.
