Variation Orders in a Dubai Renovation: How to Price and Approve Changes (2026)

A variation order (sometimes called a change order) documents any departure from the scope of work in your contract. That includes additions you request, deletions you decide against, substitutions of materials, and changes the contractor says are necessary because of something uncovered on site. The core principle is simple: no change gets done until it is written down, priced, and approved in writing by you. If it is not in a variation order, it is not agreed.

This matters because the scope of work and the contract price only mean something if changes to them are controlled. A contractor who does extra work on a verbal nod can later bill whatever they like for it, and you have no agreed figure to dispute. Equally, a change you casually mention can balloon in scope. The variation order pins both sides down at the moment of decision, when the facts are fresh and neither party is under pressure.

The fairest way to price variations is to agree the basis up front, in the original contract. Ask for a schedule of rates - the contractor's price per square metre of tiling, per point of electrical work, per linear metre of joinery - so that when a change comes up, it is priced against rates you already accepted rather than a number invented on the spot. Without this, every variation becomes a fresh negotiation with all the leverage on the contractor's side, because the walls are already open and you cannot easily walk away.

For genuinely unforeseen work uncovered on site, such as failed waterproofing or corroded pipework, expect the contractor to show you the problem, photograph it, and quote before proceeding. Be wary of round-number variations with no breakdown, and of a pattern of small extras that individually look trivial but add up. A reasonable variation itemises materials and labour; a suspicious one is a single lump sum with a shrug.

A variation log is a single running document - a shared spreadsheet works well - listing every variation with its number, date, description, cost impact, time impact and approval status. It gives you, at any moment, one number: the current contract total including all agreed changes. Owners who keep this log always know where they stand; owners who do not are the ones who get a shock at the final invoice.

The log also protects you against the most common billing surprise, where a contractor presents a stack of unagreed extras at handover. If a claimed extra is not in the log with your sign-off, it was not agreed, and your contract should say exactly that - that no variation is payable unless recorded and approved in advance. Review the log at each site visit and each milestone payment, so it never falls out of date.

Variation orders can be abused. The classic pattern is the low-ball quote: a contractor wins the job with a suspiciously cheap price, then recovers margin through a steady stream of variations once you are committed and the demolition is done. Another is the manufactured surprise, where routine work is presented as an unforeseen extra. This is exactly why comparing quotes against one detailed written scope before you sign matters so much - a thin scope leaves room for endless extras.

Your defences are the schedule of rates, the requirement that all variations be written and pre-approved, and your willingness to say no. You are entitled to see evidence for any claimed unforeseen condition, to get a breakdown, and to decline a change or seek an alternative. If a contractor does extra work without an approved variation and then demands payment, your contract - stating no unrecorded variation is payable - is your protection. Document any dispute in writing as it happens.

Everything above only works if it is in the contract from the start. Before signing, make sure the contract includes a schedule of rates, a clause that no variation is valid or payable unless recorded in a written, pre-approved variation order, and a clause that unforeseen conditions must be evidenced and quoted before work proceeds. Combine this with staged milestone payments and a 5 to 10 percent retention held until snagging, and variations lose most of their power to blow up your budget.

Handled this way, variations become what they should be - a normal, transparent mechanism for managing change - rather than a slow-motion overrun. The owners who stay in control are not the ones who refuse all changes; they are the ones who insist every change goes through the same simple written process, every time, from day one.
