29CHAPTER 4 : TECHNICAL REPORTVARIATION ORDER4.1 IntroductionVariation Order (VO) is meant any additions, replacement, omission orchanges to the specifications, drawings or quantity on a contract or originalwork. Any Variation (VO) can only be performed by the contractor in theevent of a formal directive issued by the Superintending Officer (SO).- Variation to the original work is almost certain to happen in constructionprojects due to :a) Site conditions.b) Statutory requirements.c) Change in client‟s requirements.
30d) Defective contract drawings, bills of quantities, specification, etc.(including intentional abuse of variation clause since contractallows 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 necessarychanges to be made during the construction process.- Without the variation clause, changes to the original contract are notallowed. 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 toclaim under variation for carrying out the works not provided for ormeasured in the bill of quantities.- For contract based on drawings and specifications – the contractor doesnot have the right to claim under variation for carrying out all worksincidental or necessary for the completion of the work even though thoseworks are shown in the drawings and described in the specifications.
