Variation orders should be one of the more profitable parts of a construction project — additional scope, priced on the contractor’s terms, agreed before the work starts. In practice, for many contractors in the UAE, they are one of the biggest sources of lost margin. Work gets instructed verbally on site, priced informally, executed immediately under time pressure, and only invoiced — or disputed — months later, by which point the contractor has lost most of its leverage.
Getting variations right is not about being difficult with clients. It is about protecting money the contract already entitles the business to.
What Is a Variation Order?
A Variation Order (VO) is an instructed change to the scope, specification, or sequence of the contracted works — anything from an added feature, a design change, or a different material specification, to removed scope. Under FIDIC and most standard UAE contract forms, variations are priced using the contract’s agreed rates where applicable, or a fair valuation method where no applicable rate exists, and should be instructed and agreed in writing before — or as close as possible to — the work being carried out.
Benefits of Managing Variations Properly
A disciplined variation process protects three things at once: the project’s profit margin, since variations priced and agreed in advance are priced on the contractor’s terms rather than negotiated backward from an invoice the client is already resisting; the project’s cash flow, since agreed variations get certified and paid on the normal payment cycle rather than sitting in dispute; and the contractor’s relationship with the client, since a transparent, documented variation process creates far less friction than a surprise invoice for undocumented extra work.
Cost of Getting Variations Wrong in the UAE
The real cost of a weak variation process isn’t a single bad invoice — it’s the compounding pattern across a project. Contractors who don’t formally instruct and price variations before executing them routinely recover 30-60% less than the work was actually worth, because the final negotiation starts from “prove you did this and prove what it cost” rather than from an agreed instruction and rate. On a mid-sized Dubai project with a dozen or more variations over its lifecycle, that gap is frequently the difference between a profitable project and a break-even one.
How the Process Works (4 Steps)
- Consultation. Every variation starts with establishing whether an instruction genuinely falls outside the original contracted scope, and under which contractual mechanism it should be priced — agreed rate, pro-rata rate, or a fair valuation submission.
- Planning. Before any work is executed, the variation is priced and a written instruction or quotation is issued to the Engineer or client for approval — covering scope, price, and any time impact, so there is a clear record of what was agreed and when.
- Implementation. Only once the variation is approved — or, where urgency requires proceeding before formal approval, once a clear paper trail documents the instruction to proceed — is the work carried out, with records kept of actual resources used in case the final valuation is disputed.
- Results & Follow-Up. The variation is submitted for certification and payment through the normal process, with any unresolved pricing disagreements escalated and negotiated from a position of documented evidence rather than after-the-fact reconstruction.
Before and After
Before: verbal instructions, work carried out under time pressure, informal pricing, and invoices negotiated down months later with little documentation to support the contractor’s position.
After: every variation instructed and priced in writing before execution, valued against the contract’s own mechanism, and certified through the normal payment cycle — with margin protected rather than negotiated away.

FAQs
Can a contractor refuse to carry out a variation until it’s priced and agreed?
This depends on the specific contract’s variation clause, but many standard forms allow the contractor to request pricing agreement before proceeding, particularly for significant scope changes. Reviewing the specific clause before escalating this on site is important.
What if the Engineer instructed the variation verbally and won’t confirm it in writing?
Confirm it yourself, in writing, immediately — a short email summarizing what was instructed, by whom, and when, sent to the Engineer, creates a record even without their written instruction. Many contracts also allow the contractor to treat its own written confirmation as valid if not disputed within a set period.
How is a variation priced when there’s no applicable rate in the contract?
Most standard forms, including FIDIC, provide for a “fair valuation” or similar mechanism based on reasonable cost plus profit, used when the existing bill of quantities rates don’t reasonably apply to the new scope.
Does a variation automatically extend the project timeline?
Not automatically — the time impact of a variation needs to be assessed and claimed separately, similar to any other delay event, and is not assumed just because additional scope was added.
Should variation claims be submitted individually or batched together?
Individually, as they occur, wherever practical. Batching variations and submitting them all at project close makes each one harder to substantiate and gives the Employer’s representative more room to dispute the whole batch rather than approving items as they’re agreed.
Conclusion
Variations are contractual entitlement, not goodwill from the client — but only when they’re instructed, priced, and documented the way the contract expects. The contractors who protect their margin on variations are not the ones who argue hardest at the end of the project. They’re the ones with a process that gets it right from the first instruction.
