Costs

The hidden costs in a Dubai fit-out budget

An incomplete scope can cause a budget overrun. Check exclusions before comparing quotes.

The per-square-foot rates in the rates guide describe different scopes: some cover design services, while others advertise turnkey work. Ask what each quoted rate includes before adding other project costs.

Fees and approvals

Preliminaries and site costs

Worth knowing

Preliminaries are typically a meaningful share of a small project and a smaller share of a large one, because they are largely fixed. This is the main reason a single-room job looks expensive per square foot, and why doing works in one package beats doing them in two.

Provisional sums and prime costs

A provisional sum is an allowance for work that has not been defined yet. A prime cost sum is an allowance for an item the client will choose later. Both are legitimate. Both are also the most common mechanism by which a fixed price becomes a larger price.

The discipline is simple: before signing, ask for every provisional sum to be either resolved into a firm price or reduced to a named allowance with a stated basis. If a quotation contains a large undefined sum for "MEP works" on a renovation, that is not a price for MEP works — it is a placeholder, and the real number will arrive as a variation.

Procurement and long-lead items

Order samples and confirm availability before the design is frozen, not after. A finish that is out of stock in the week you need it becomes either a delay or a substitution, and both cost money.

Snagging, defects and the tail of the project

The last five per cent of a project takes a disproportionate share of the time and the money. Making good defects, obtaining the completion certificate, resolving the final account and closing out the paperwork are all real costs, and they land after the client has usually stopped expecting to spend.

Retain a percentage of the contract value until practical completion and the defects list is closed. A contractor who will not accept retention is telling you something about how the end of the job will go.

Contingency

A contingency is not optimism, it is the acknowledgement that a renovation contains unknowns until the walls are opened. The appropriate level depends on how much you know going in:

Contingency guidance by project knowledge
SituationReasonable contingency
New build, developer finish, nothing openedLow — the building is known and documented
Full renovation of a property you have inspected thoroughlyModerate — services condition is still partly unknown
Renovation of an older property, services unverifiedHigher — wiring, plumbing and waterproofing are all unknowns
Structural alterationHigher — what is found behind the finishes drives the engineering
Heritage or unusual constructionHighest — assume surprises

A contingency you do not spend is a saving. A saving you already spent is a variation you have to fund. Keep it separate in your own tracking, and release it only against a defined item.

Before you commit to a budget

Work through the planning and handover checklists and use the budget calculator to add these categories to the construction rate. Enter any excluded fees, preliminaries, procurement and external works yourself, then choose a contingency assumption. The calculator does not estimate these additions automatically.
