The document that turns a drawing into a price. What a BOQ contains, why contractors lean on it, and how homeowners can read one without a QS qualification.
The bridge between design and price
A Bill of Quantities (BOQ) is a structured list of the work and materials a building project needs, measured from the drawings: cubic metres of excavation, square metres of brickwork, numbers of doors and windows, and so on. Pricing those measured quantities is how a design becomes a cost.
In South African residential construction, a detailed BOQ is typically prepared by a quantity surveyor. Contractors use it (or build their own version) to price work consistently — which is also why two quotes for the same house can differ simply because they measure different things.
How to read one without a QS qualification
You do not need to audit a BOQ to benefit from it. Three habits go a long way: check that the sections cover the whole house (foundations to roof to finishes), look for quantities that seem out of proportion to your plans, and pay attention to what is described as a provisional sum — an allowance for work that cannot yet be measured accurately, like underground conditions.
Also watch the exclusions. What a BOQ deliberately leaves out (VAT, professional fees, site clearance, landscaping) is as important as what it includes.
How BuildEase helps
BuildEase is being developed to organise the construction information available for your project into structured quantities and BOQ-style cost breakdowns — with every figure labelled Verified, Estimated or Assumed, and the assumptions and exclusions stated alongside.
It supports your understanding of the document; it is not a substitute for a quantity surveyor's formal BOQ where one is required.
THE TAKEAWAY
A BOQ is just your house, measured. BuildEase's BOQ & Cost Intelligence is being built to give you that measurement in readable form.
