Bill of quantities software

Build a clearer preliminary BOQ from your drawings.

apstrog connects dimensioned construction drawings to structured, reviewable quantities and editable preliminary bills of quantities, so your team can review the source before pricing or exporting.

BOQ, explained for the workflow

What does a bill of quantities do?

A bill of quantities turns project scope into an organised schedule of work items and quantities. It gives a construction team a common structure for discussing what is included, how much work is represented and what still needs an assumption, rate or professional decision.

A BOQ may be used during estimating, tender preparation, procurement, cost planning, valuation or commercial review. The level of detail and the measurement rules depend on the project, contract and professional standard being used.

apstrog focuses on the drawing quantity stage. It helps turn measurable information from dimensioned PDF, DWG and DXF plans into a preliminary, editable BOQ that your team can check and continue in its existing process.

From drawing to BOQ

A quantity workbook your team can interrogate.

A useful preliminary BOQ should give people enough context to review it—not just a total with no source. apstrog is intended to keep the drawing relationship and measurement categories close to the output.

Who uses the output

One BOQ workflow, several construction decisions.

The core user prepares or reviews the quantities. Adjacent users need the result to discuss design, feasibility, scope or the next commercial step.

Core

Quantity surveyors

Use a structured preliminary BOQ as a reviewable starting point for measurement, cost planning and commercial work.

Core

Estimators & contractors

Move drawing quantities into bid, budgeting and procurement conversations without rebuilding every line manually.

Adjacent

Architects & engineers

Give design teams an earlier view of quantities that can support client discussions and scope alignment.

Adjacent

Developers & owners

Use early scope information to make feasibility and project planning conversations more concrete.

Adjacent

Project managers & consultants

Review the quantity story behind a drawing-led decision and keep the workbook ready for the next handoff.

Reviewable by design

A BOQ should show its assumptions and its source.

Use the quantity sheet as a starting point, then validate the drawing issue, dimensions, scope, units and assumptions against the project information. Keep the professional sign-off with the person responsible for the estimate or bill.

BOQ software FAQ

Questions about bills of quantities.

What is BOQ software?

BOQ software helps construction teams organise a bill of quantities: a structured list of work items and quantities used for estimating, tendering, procurement or cost planning. Different tools may also add rates, pricing, supplier comparisons or project cost control.

Does apstrog produce a bill of quantities?

apstrog is designed to produce structured, editable preliminary BOQs from properly dimensioned construction drawings. Pricing and rate-library features are separate from the drawing quantity workflow.

Who needs BOQ software?

Quantity surveyors, estimators, contractors, design-build teams and construction consultants commonly prepare or review bills of quantities. Architects, engineers, developers and project managers may also use early quantity information to support project decisions.

Can I export a BOQ to Excel?

Yes. apstrog is designed to keep the output editable and exportable to formats such as Excel so it can continue into an existing estimating, budgeting or quantity surveying process.

Is a preliminary BOQ ready for a contract?

No. A preliminary BOQ is a starting point for review and planning. A qualified professional should check the drawings, measurement rules, assumptions, specifications, rates and contractual requirements before relying on it.
