What Does a Quantity Surveyor Do in Dubai?

A quantity surveyor (QS) manages the cost of a construction project from initial feasibility through to final account. That covers preparing cost plans and estimates, measuring the works, producing bills of quantities, running the tender process, certifying interim payments, assessing variations, and agreeing the final account once the project completes.

In practice, a QS is the person who turns a design into a number — and then defends that number through every stage of construction, from the first sketch to the last snag.

The earliest and arguably most important QS work happens before construction starts. A feasibility budget, prepared at the point a developer is considering a plot or a scheme, tells them what the project is realistically likely to cost — long before the design is finalised.

As the design develops, that early estimate is refined into an elemental cost plan, breaking the anticipated cost down by building element: substructure, superstructure, external envelope, internal finishes, MEP services, external works. This structure, formalised under the RICS New Rules of Measurement (NRM 1), gives the developer a transparent, auditable basis for the budget at every design stage — not a single lump-sum guess that either holds or doesn't.

Once the design is sufficiently developed, the QS measures the works in detail and prepares a bill of quantities (BOQ) — a comprehensive, itemised schedule of every element of the build, quantified to RICS NRM 2 and, on many UAE and GCC projects, to the Principles of Measurement International (POMI).

This document does two things. First, it becomes the basis on which contractors price their tenders — meaning every bidder is quoting against the same, independently measured scope, rather than each interpreting the drawings differently. Second, it gives the developer a benchmark: an independently priced estimate to compare incoming tenders against, so a contractor's number isn't the only number in the room.

Without a properly measured BOQ, tender evaluation becomes guesswork. Bids can't be compared like-for-like, and the lowest number often wins — regardless of whether it's actually the best value, or simply the most aggressively priced bid with the most variations waiting to surface later.

Once the contractor is on site, the QS's role shifts to active cost management. Monthly interim valuations assess how much work has genuinely been completed and certify payment accordingly — protecting the developer's cash flow and removing the contractor's incentive to over-claim against progress.

Variations — the inevitable changes that occur on almost every project — are measured and priced independently before they're approved, with full substantiation. This is where a huge amount of budget leakage typically occurs on unmanaged projects: a 'small revision' requested on site, priced by the contractor alone, and approved without independent scrutiny, often at a significant premium.

At completion, the QS reconciles the full cost history of the project — the original contract sum, every agreed variation, and any claims — into a final account. Done properly, this is a defensible, line-by-line settlement that closes the project cleanly, without the disputes that so often arise when cost tracking has been informal or contractor-led throughout.

This final account also becomes a valuable record for the developer: a documented cost history that can inform the budget for the next development, and a clear picture of where the original plan held and where it moved.

Quantity surveying is a regulated profession in markets like the UK, but in the UAE, the title carries no legal protection — anyone can call themselves a quantity surveyor. That makes independent, verifiable credentials — most notably RICS Chartered status — one of the only reliable signals a developer has that the person managing their cost strategy is genuinely qualified and accountable to a recognised professional standard, not just to the firm that employs them.
