What Is a BOQ in Construction? A Guide for UAE Contractors
A Bill of Quantities – commonly called a BOQ – is one of the most important documents in any construction project. If you have ever submitted a tender, argued about variation costs, or tried to understand why your project went over budget, you have encountered a situation where a properly prepared BOQ either helped you or was missing when you needed it. This guide explains what a BOQ is, what it contains, and when you need one in the UAE construction market.
What Is a BOQ?
A Bill of Quantities is a document that lists every item of work in a construction project – measured by quantity, described by type, and priced per unit. It is the basis for pricing a tender, valuing completed work, and assessing the cost impact of changes.
A typical BOQ line item looks like this:
- Description: Supply and lay 600x600mm porcelain floor tiles, including adhesive bedding and grout, complete
- Unit: m²
- Quantity: 285
- Rate: AED 95 per m²
- Amount: AED 27,075
Multiply this across every trade and every element of the building – structure, finishes, MEP, external works – and you have a complete BOQ.
What a BOQ Contains
A well-prepared BOQ is divided into sections by trade or work package:
- Preliminary and general items: Site setup, temporary works, insurance, project management
- Substructure: Excavation, piling, foundations, ground slab
- Superstructure: Concrete, formwork, reinforcement, blockwork, structural steel
- Roofing and waterproofing
- External works: Facades, cladding, glazing
- Internal finishes: Plastering, screeds, tiling, painting, suspended ceilings
- Joinery and fittings: Doors, windows, kitchen, wardrobes
- Mechanical works: HVAC, plumbing, drainage, firefighting
- Electrical works: Power, lighting, data, security, DEWA connection
- External works and landscaping
Who Prepares a BOQ?
In the UAE, a BOQ is typically prepared by a quantity surveyor, a technical office, or an estimating consultant. For government projects, the consultant issues a BOQ with the tender documents. For private projects, the contractor often prepares their own BOQ from the drawings for internal budgeting and tender pricing.
When Do You Need a BOQ in UAE Construction?
- Tender pricing: You need a BOQ to price a competitive tender accurately. Without one, you are guessing – and guessing wrong costs you either the contract (too high) or money (too low).
- Project budgeting: A BOQ prepared before construction starts gives you a realistic budget. Most UAE villa projects that go over budget do so because they had no BOQ – only a rate per square foot that excluded key items.
- MBRHE housing loan applications: The Mohammed Bin Rashid Housing Establishment requires a detailed BOQ as part of the loan documentation package.
- Bank financing: Construction finance in the UAE typically requires a BOQ to determine drawdown milestones and verify progress payments.
- Variation valuation: When scope changes on a project, the BOQ unit rates are used to price the variation. Without a BOQ, every variation becomes a negotiation.
- Dispute resolution: If a project ends in a dispute, the BOQ is the primary document used to assess contractor claims and client counterclaims.
BOQ vs Rate Per Square Foot
Most contractors in the UAE can quote a price per square foot. This number is useful as a quick sanity check, but it hides everything that matters: the structural system, the specification level, the site conditions, and what is included or excluded. A project with an unusual structural design, a basement, or high-specification finishes will cost significantly more per square foot than a standard villa – the rate per square foot will not tell you that. A BOQ will.
How to Get a BOQ for Your Project
