What we deliver
Measured quantities and estimation support so budgets stay grounded in the drawings—not guesswork.
A bill of quantities (BOQ) turns drawings into measurable work. ZADS prepares BOQ and estimation support so tenders, negotiations, and budgets stay grounded in the approved set, not guesswork.
We work from coordinated drawings so quantities track the same rooms, finishes, and details the contractor will build. Final BOQ always remains subject to site survey and issued revisions.
What’s included
