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.

29

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.

34

4.4 Procedure of Variations

Figure 4.4.1 – Variations Process

35

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)

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.

36

- 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.

37

Oral instruction Confirmation in writing

≤ 7 Days

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.

4.5.3 Compliance to Instructions

‘..Upon the issuance of such Variation Order, the Contractor shall

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.

b) Engage another contractor to carry out the work

39

‘…. All cost and expenses incurred in connection with such

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 :

a) the contractor will not be paid for the work.

b) the contractor is in breach of contract for not carrying out the work

according to the contract – he may have to remove the work and

replace it with the work according to the contract.

40

- In the case of differences between actual quantities and the quantities

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.

41

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)

42

- 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.

- The contractor is required to take part in the measurement even though

the contractor does not participate in the measurement after being told to

do so.

4.7.2 Contract Rates

‘the rates in the Bills of Quantities… shall determine the valuation of

work of similar character and executed under similar conditions as

work priced therein.’ (Clause 25.1 (a)).

‘the rates in the Bills of Quantities shall determine the valuation of

items omitted, …’ (Clause 25.1(c)).

- These contract or B.Q. rates are applicable for valuing:

executed under similar conditions to the work in the Bills of

quantities.

b) Omitted work.

44

- The rates are taken from the bills of quantities. Reference to the bills of

4.7.3 Adjusted contract rates / pro-rata rates

‘The said rates, where work is not of similar character and executed

under similar conditions as aforesaid, shall be the basis of rates for the

same, as far as may be reasonable…’ (Clause 25.1(b))

‘… if the omission vary substantially the conditions under which any

remaining items of work are carried out, the rates of such remaining

items shall be valued under rule (b)’ (Clause 25.1(c))

45

- These are the rates from the bills of quantities with adjustment for

Example 2 : Calculation of adjusted rate.

Assumptions :

Contract rate for 100mm x 100mm x 1.00 m long reinforced pre-cast concrete

lintel

= RM 10.00 / No.

The length of lintel is to be changed to 1.20m.

Pro-rata rate for 100mm x 100mm x 1.20 m long reinforced pre-cast concrete

lintel

= 1.201.00

x RM 10.00 = RM 12.00 / No.

46

a) Different work i.e. varied works which are different in character or

executed under conditions different from those included for in any

bill rates.

b) Remaining items of work if they are to be carried out under very

different condition when part of the original work has been omitted.

- To be used in the event where B.Q. rates and pro - rata rates are not

suitable.

- These rates normally consist of the cost plus a reasonable percentage for

profit.

- These rates are required to be agreed between the S.O. and the

contractor.

4.7.4 Day Work Price

- This method of valuation is normally used where the varied work cannot

be properly measured and values and a valuation at rates is not

practicable (example : Demolition work).

47

the works have been done the following particulars to the S.O. for

verification :

a) Receipts as a proof for the amount paid

b) Particulars on :

- the workmen employed

included in the appendices to the contract document. It is important

for the S.O. to make sure that all items in this section are priced by

the contractor before the singing of the contract.

b) In the absence of (a), the actual cost of resources.

- The calculation of day work price includes the actual cost incurred by the

contractor and an allowance of 15% for profit.

48
