Bill of Quantities
Know what your project costs, item by item — before you sign, and every month after.
Overview
What our bill of quantities service covers
A bill of quantities turns a design into a measured, priceable schedule of everything the project requires. It is what lets you compare tenders on a like-for-like basis, challenge a variation with evidence, and know where the money has actually gone.
We prepare cost estimates and bills of quantities, produce tender documentation, and provide the ongoing cost control and value engineering support that keeps a project inside its budget rather than merely reporting that it left.
Why engage us
Five reasons clients bring bill of quantities to TopHall
Measured quantities, not rules of thumb
Costs are built from measured work rather than rate-per-square-metre approximations, which is the difference between a budget and a hope.
Tenders you can actually compare
Proper tender documentation forces bidders to price the same scope, exposing the low bid that has simply omitted work.
Variations assessed on evidence
When a contractor claims a variation, it is measured and checked against the bill rather than negotiated on assertion.
Value engineering that keeps the design intent
Where savings are needed we identify them against buildability and specification, instead of simply stripping quality out of the finishes.
Cost control through to final account
Cost is tracked for the life of the project, so the final account is a confirmation rather than a surprise.
How it works
Our process
Each stage has a defined output, so you always know what you are receiving and what happens next.
- Step 01
Drawing review
We review the design and identify what can be measured and what needs clarification.
- Step 02
Measurement
Quantities are taken off and the bill is compiled.
- Step 03
Cost estimate
Rates are applied to produce a realistic project cost.
- Step 04
Tender documentation
Documents are issued so contractors price a consistent scope.
- Step 05
Cost control
Valuations, variations, and the final account are managed through construction.
Questions
Frequently asked questions
Can you prepare a bill of quantities from another firm's drawings?
Yes. We will review the drawing set first and tell you where it lacks the detail needed for accurate measurement.
How accurate is the initial cost estimate?
Accuracy depends on how developed the design is. We state the basis and the expected range rather than presenting an early-stage figure as a fixed price.
Do you provide quantity surveying during construction?
Yes — interim valuations, variation assessment, cost reporting, and final account are part of our cost control service.
