Villa Construction Glossary: Dubai & Abu Dhabi

Contracts, cost plans and site meetings come with their own language. Knowing what a provisional sum, an extension of time or a defects liability period actually means, and who is responsible for it, is the first step to keeping control of your budget and programme.

Each definition says who usually does what: the owner, the owner's DM-registered consultant, the contractor, or Eastbridge as your client-side project manager. This is general information, not legal or technical advice for your project. For contract questions, take advice from a UAE-qualified lawyer.

Find a term

A

Advance payment guarantee

A bank guarantee the contractor provides in return for an up-front payment from the owner, usually at mobilisation. If the contractor fails to perform before the advance has been earned back, the owner can call on the guarantee. The advance is normally recovered by deducting an agreed share from each interim payment, and the guarantee should reduce as it is repaid. Check the wording, the issuing bank and the expiry date before releasing any money.

Affection plan

A Dubai plot document setting out the plot number, dimensions, area and the planning controls that apply, such as permitted use, height and setbacks. It is one of the first things the owner's consultant needs before design can start, and one of the first things to read before you buy a plot. Which body issues it depends on where the plot sits. Make sure the copy you rely on is current.

Arbitration

A private way of resolving a contract dispute, decided by one or more arbitrators instead of a court. Many construction contracts in the UAE choose arbitration, and the clause usually names the rules and the seat. It can be slow and costly, so on a villa it is a last resort after negotiation and other routes have failed. Whether and how to start a claim is a question for a UAE-qualified lawyer.

As-built drawings

Drawings that record the villa as it was actually built, including every change made on site, the true routes of pipes, cables and drainage, and the final positions of equipment. They are prepared on the contractor's side and checked by the owner's consultant. Owners need them for maintenance, future alterations and resale. Make their delivery a condition of handover, not a promise for later.

B

Bill of quantities (BOQ)

A document that breaks the work into itemised quantities, such as cubic metres of concrete or square metres of tiling, so that contractors can price the same scope line by line. A good BOQ makes bids comparable and gives agreed rates for valuing variations. A poor one, with gaps or vague items, invites claims later. On a lump sum contract, check what the contract says about errors in the quantities.

Building Completion Certificate

The certificate the permitting authority issues once the finished villa has passed its completion inspection. In Dubai's residential procedure, a joint inspection by the authority's departments, including Civil Defence where needed, comes before the certificate, and service connections follow it. In Dubai's residential procedure, service connection follows the completion certificate, so it should be a defined milestone in the contract and the programme, not an afterthought.

Building in Dubai platform

The Dubai government digital platform launched in October 2023 that brings together building services from land and design through permits, construction, completion, connection and later alterations. Applications are made by the registered consultant or contractor, not usually by the owner. Owners rarely log in themselves, but it helps to know where an application sits and what the authority has asked for.

Building permit

The authority's approval to start construction, issued with stamped drawings. In Dubai it comes from Dubai Municipality, Trakhees or the Dubai Development Authority, depending on where your plot sits. In Abu Dhabi, the municipalities issue permits through TAMM. The owner's registered consultant prepares and submits the application, and the contractor must have the permit before work starts. Building without one can lead to enforcement action by the authority; take advice from a UAE-qualified lawyer if work has started without one.

Built-up area (BUA)

The total covered floor area of a villa, usually measured to the outside of the walls and including every floor. Definitions differ between authorities and master developers, especially for terraces, balconies, basements and roof structures, so always ask which definition a figure uses. Build costs are commonly quoted per square foot of BUA, which makes the definition matter when you compare quotes.

C

Civil Defence approval

The fire and life safety approval for a building, covering items such as fire alarms, escape routes and fire-rated construction. In Dubai, Civil Defence is linked to the unified building permit window, and it joins the completion inspection where needed. The owner's consultant designs to meet the requirements and the contractor installs the systems. A failed inspection here can hold up the completion certificate.

D

Daywork

Work paid on the time and materials actually spent, at agreed hourly and material rates, instead of at a measured or fixed price. It is used for small, unforeseen items that are hard to price in advance. Daywork sheets should be signed off on the day the work is done. Without that discipline, daywork is one of the easiest ways for a final account to grow.

Decennial liability

A ten-year liability under the UAE Civil Transactions Law. The contractor and the architect who designed and supervised the work can be jointly liable for collapse, total or partial, and for defects that threaten the building's stability, usually from handover. Commentators note that the parties cannot contract out of it. It is separate from the shorter defects liability period. Take advice from a UAE-qualified lawyer on any claim.

Defects liability period

A period after completion, set in the contract and often a year, during which the contractor must return and put right defects that appear. Some contracts call it the defects notification period. Retention or a bond is often held until it ends. Keep a dated list of defects as they appear and report them in writing, well before the period expires.

Department of Municipalities and Transport (DMT)

The Abu Dhabi government department that regulates planning and building in the emirate, including the private villa regulations it amended in September 2025. Building permits are issued by the municipalities through the TAMM platform. In August 2025 DMT allowed contractors to apply directly for some minor works, such as small extensions, pools, canopies and fences.

See also: TAMM, Setback, Building permit

Design development

The stage where the agreed concept is worked up into coordinated architectural, structural and MEP designs with enough detail to apply for approvals and to price. Most cost is committed here, long before anyone starts on site. It is the best moment to test the design against the budget, because changes are cheap on paper and expensive once work is built.

DEWA connection

Connecting a Dubai villa to the electricity and water network of the Dubai Electricity and Water Authority (DEWA). In Dubai's residential procedure, permanent connection follows the completion certificate. Applications and load calculations sit with the consultant and contractor, but owners feel any delay, because a finished villa without power cannot be commissioned or lived in. In Abu Dhabi, connections are made by the local distribution company.

E

Extension of time (EOT)

More time granted to the contractor to finish, because of a delay the contract says is not the contractor's risk, such as late owner instructions or variations. It moves the completion date and protects the contractor from liquidated damages for that period. A valid claim normally needs a timely notice, evidence and an updated programme. Owners who keep good records and decide promptly give contractors little to claim.

F

FF&E (Furniture, fixtures and equipment)

The loose furniture, decorative lighting, soft furnishings, art and some appliances that make a villa liveable. At the top of the market it can be a large share of the total spend, yet it is often left out of early budgets. Decide early whether FF&E sits in the contractor's scope, an interior designer's scope or with the owner, and budget for it separately.

FIDIC

A family of international standard construction contracts published by the International Federation of Consulting Engineers. The Red Book is for work designed by the owner's team and the Yellow Book for contractor design. FIDIC forms are widely recognised in the region, usually with heavy amendments. For a private villa they can be more than is needed, and Dubai Municipality's guidance forms or a bespoke contract may suit better.

Final account

The agreed total of everything owed under the building contract once the work is done: the contract sum, plus or minus variations, adjustments to provisional sums, remeasured quantities and settled claims. Agreeing it promptly closes the contract. Left open, it becomes a negotiation months after the team has moved on, and the owner has lost most of their leverage.

Fit-out

The interior work that turns a built shell into a finished home: joinery, kitchens, bathrooms, flooring, ceilings, lighting and decoration. On a new villa it is usually part of the main contract. On a renovation it may be the whole project. Fit-out is where specification choices and late decisions do most damage to cost and programme, so settle the finishes early.

G

G+1

Shorthand for a building's height: ground floor plus one upper floor. You will also see G+2, B+G+1 for a basement, and +R for a roof level with an enclosed structure such as a stair or majlis. The permitted height for a plot is set by its planning regulations and the master developer's guidelines. Check it before you plan the accommodation you need.

Gross floor area (GFA)

A planning measure of floor area, used to control how much can be built on a plot. What it includes and excludes, such as basements, parking or plant space, depends on the authority's and the master developer's definitions, so it can differ from the built-up area for the same villa. Planning limits are usually set in GFA. Confirm which measure each figure uses.

H

Handover

The point at which the contractor hands the finished villa to the owner, with keys, test certificates, manuals, warranties and as-built drawings. It usually coincides with practical completion or taking over under the contract, and it starts the defects liability period. Do not accept handover with a long snagging list and no agreed dates for clearing it.

I

Interim payment

A stage or monthly payment to the contractor during the build, based on work completed and materials on site. The contractor applies, the owner's consultant checks the application against progress and contract rates, and the approved amount is paid less retention and other agreed deductions. Paying ahead of the work, or paying unchecked applications, gives away the owner's main leverage.

J

JCT

The Joint Contracts Tribunal, which publishes the standard building contracts most used in the United Kingdom, from minor works to design and build. JCT contracts use practical completion and a rectification period instead of taking over and defects notification. Our founder built under JCT contracts for 21 years. They are rarely used for UAE villas, but British owners often recognise the concepts.

L

Letter of intent

A letter telling a contractor that the owner intends to award the contract, sometimes allowing limited early work before the full contract is signed. It can save time but carries risk: if the contract is never agreed, it may be unclear what has been promised and what is owed. Keep it short, capped in value and time-limited, and get the full contract signed quickly. Have a UAE-qualified lawyer review the wording before it is signed.

See also: Tender, Mobilisation, Lump sum

Liquidated damages (LDs)

A pre-agreed amount, usually per day or week, that the contractor pays the owner if the villa is finished late without a valid extension of time. The rate should be set in the contract, often with a cap. How enforceable liquidated damages are, and whether a court may adjust them, is a matter of UAE law, so take advice from a UAE-qualified lawyer.

Lump sum

A contract where the contractor agrees a fixed price for a defined scope of work, so the risk of quantities is largely the contractor's. It is only as fixed as the drawings and specification behind it: gaps become variations. Many villa contracts mix a lump sum for most of the work with remeasurable items and provisional sums. Know which items sit where.

M

Master developer

The company that planned and controls a community, such as Nakheel on Palm Jumeirah, Emaar in Emirates Hills, Meraas on Jumeirah Bay, Aldar on Saadiyat and Modon on Hudayriyat. It sets design guidelines and issues its own NOCs before the authority will process a permit. In Nakheel communities, renovation and extension approvals start with an NOC application through Nakheel's portal.

MEP (Mechanical, electrical and plumbing)

The building services of a villa: air conditioning and ventilation, power, lighting, data, water supply, drainage, and often pool plant and fire systems. In a Gulf villa MEP is a large part of the cost and the main source of problems after handover. Ask for coordinated MEP drawings before work starts, and insist on proper testing and commissioning before you accept the villa.

Method statement

A document from the contractor describing how a particular piece of work will be carried out safely and correctly: sequence, equipment, materials, labour, checks and safety measures. Typical examples are excavation and shoring, waterproofing and pool construction. The owner's consultant reviews it. For owners, a well-written method statement is a good sign of a contractor who has thought the job through.

N

No objection certificate (NOC)

A written confirmation from an authority, master developer or utility that it has no objection to a proposed design or piece of work. A Dubai villa permit usually needs several, collected through the unified building permit window. In Nakheel communities, renovations and extensions start with a Nakheel NOC application. The consultant gathers most NOCs. Missing ones are a common cause of early delay.

Nominated subcontractor

A specialist, such as a pool, lift or smart home installer, chosen by the owner's side but employed by the main contractor. Nomination gives the owner control over who does important work, but it can blur responsibility: when the specialist is late, the main contractor may claim it is not their fault. Be clear in the contract who carries that risk.

O

Owner's representative

An independent adviser who acts only for the owner, paid only by the owner, managing the project on their behalf: budget, programme, team selection, progress reporting, payments and decisions. Eastbridge is a client-side project manager in this sense. We represent the owner alongside the owner's DM-registered consultant and the contractor, and do not replace the consultant of record that the authorities require.

P

Performance bond

A guarantee, usually from a bank, that the owner can call on if the contractor fails to perform the contract, for example by abandoning the site. The amount is a percentage of the contract sum agreed in the contract. Check whether the bond is on demand or conditional, who issues it, and when it expires: a bond that lapses before completion is worth little.

Plot coverage

The share of the plot that the building's footprint may cover, usually expressed as a percentage of plot area and set by the planning regulations or the master developer's guidelines. Together with height limits and setbacks, it decides how large a villa a plot can take. Check it before you buy, rather than discovering at design stage that your brief will not fit.

Q

Quantity surveyor (QS)

A construction cost specialist who measures and values work. On the owner's side a QS may prepare cost plans and bills of quantities, value interim payments and variations, and agree the final account. Contractors employ their own. On a villa, the owner's consultant often provides the cost role. Check who is actually doing it, and for whom.

R

Remeasure

A contract, or part of one, where the work is measured as built and paid at agreed rates, so the final cost moves with the quantities. It suits work that cannot be fully defined at the start, such as excavation or piling. The quantity risk sits mainly with the owner, so you need reliable measurement and a clear record of what was actually done.

Request for information (RFI)

A formal written question from the contractor to the design team, asking for missing information or for a conflict in the drawings to be resolved. A steady flow of RFIs is normal. A flood of them points to incomplete design, and slow answers can support a delay claim. A log of RFIs, with dates raised and answered, is a useful health check on any project.

Retention

A percentage held back from each payment to the contractor, as security for completion and defects. Typically part is released at completion and the balance at the end of the defects liability period. The percentage is negotiated. What matters most is that the contract says clearly how much is held, when each part is released and on what conditions.

S

Setback

The minimum distance a building must be kept from a plot boundary, set by planning regulations and the master developer's guidelines and shown on the plot documents. Setbacks, height and plot coverage together define the space a villa can occupy. In Abu Dhabi, DMT's September 2025 amendments to the private villa regulations include a 1.5 metre front setback.

Shop drawings

Detailed drawings produced by the contractor or a specialist, showing exactly how an element will be made and installed, such as joinery, glazing, stairs or MEP routes. The owner's consultant reviews them against the design before work proceeds. Owners should see shop drawings for anything visible and important to them, because this is the last cheap moment to change it.

T

Taking over

The FIDIC term for the point at which the owner takes over the completed works, confirmed by a taking-over certificate. Like practical completion, it usually releases part of the retention, stops delay damages and starts the defects notification period, and it is often the date from which decennial liability is counted. The contract sets the tests that must be passed first.

TAMM

The Abu Dhabi government services platform, through which the municipalities issue building permits for villas in the emirate. As in Dubai, applications are normally made by the registered consultant or contractor. Abu Dhabi has also moved certain inspection steps to digital reports: from October 2026, certified joint reports replace phase-closure permits for designated categories.

Tender

The process of inviting contractors to price the same defined scope so that bids can be compared fairly and a contractor chosen. A good tender gives every bidder the same drawings, specification and contract terms, and asks for prices in the same format. The owner appoints the winner. Eastbridge helps owners compare bids like-for-like and choose, alongside their consultant.

Trakhees

The regulatory arm of Dubai's Ports, Customs and Free Zone Corporation (PCFC). Its Civil Engineering Department issues building permits and carries out inspections in the areas it regulates. With Dubai Municipality and the Dubai Development Authority, it is one of the authorities on Dubai's unified building permit window. Which authority covers your villa depends on where your plot sits.

V

Value engineering (VE)

A structured review of a design to keep the function and quality the owner wants at lower cost, for example by simplifying structure or rationalising MEP. Done early, it saves real money. Done late, or used as a label for cheaper materials, it simply cuts quality. Ask for every proposed saving in writing, with what changes and what it saves.

Variation

A change to the work described in the contract, whether an addition, omission or change in specification. Some contracts call it a change order. Variations should be instructed in writing by whoever the contract authorises and priced before the work is done, not argued over afterwards. Unmanaged variations are the main reason villa budgets overrun.

W

Warranties and guarantees

Written promises from the contractor, specialists or manufacturers about the performance of particular work or products, such as waterproofing, roofing, glazing or air conditioning equipment, often for periods longer than the defects liability period. Collect them at handover, check who gives them and what voids them, and keep them with the as-built drawings and manuals.
