The problem

Stop measuring the same drawings twice.

Construction drawings already contain much of the information required for a quantity takeoff—dimensions, room layouts, wall locations, openings, schedules and annotations. But turning it into usable quantities for an estimate or BOQ still often means measurements, calculations and spreadsheet transfer. apstrog streamlines that preconstruction workflow.

How it works

Construction quantity takeoff in three steps.

Start with dimensioned PDF, DWG or DXF drawings, then keep a human review point where it matters before quantities move into an estimate or BOQ.

01

Upload your drawings

Start with architectural floor plans and other properly dimensioned PDF, DWG or DXF drawings.

02

Review detected measurements

apstrog reads dimensions, annotations and drawing geometry, then associates them with measurable building elements.

03

Generate your quantity sheet

Confirm or correct the quantities, then export an editable BOQ or quantity workbook to Excel.

Quantity coverage

Measure building quantities from drawings.

Cover the building elements that commonly create repetitive construction takeoff work, with quantities that stay clear, editable and reviewable.

Dimension-aware by design

Read the dimensions your takeoff depends on.

Construction drawings often already contain the measurements estimators, quantity surveyors and engineers rely on. apstrog uses explicit dimensions, annotations and drawing relationships as primary measurement evidence, rather than relying only on visual scale estimation.

Where information is unclear, you review the measurement before it becomes part of the BOQ.

Auditability

Source-linked quantities for reviewable BOQs.

Construction quantities should be reviewable. Rather than returning unexplained numbers, apstrog is intended to connect a measurement to its source information in the drawing before it enters a preliminary BOQ or estimate.

Every quantity stays reviewable. The BOQ remains editable.

Who it’s for

Built for people who turn drawings into construction decisions.

The core audience is the team responsible for takeoff, estimating and BOQ preparation. The adjacent audience needs the same drawing evidence earlier for design, feasibility, budgeting or project review.

Core audience

Estimators, quantity surveyors & contractors

For people who measure plans to price work, answer a bid, prepare procurement quantities or build a preliminary bill of quantities. The value is less repetitive measurement and a clearer review point before export.

Adjacent audience

Architects, engineers, developers & project managers

For teams that need early quantities from architectural or engineering drawings to test scope, discuss feasibility, compare options or align the next project conversation.

See the drawing-to-quantity workflow
01 / CORE AUDIENCE

Estimators & quantity surveyors

Create preliminary quantity takeoffs and editable BOQs from drawing sets, then spend more time reviewing scope, pricing and commercial judgement.

02 / CORE AUDIENCE

General & specialty contractors

Screen bid opportunities and prepare material quantities from PDF or CAD plans before procurement, budgeting or construction.

03 / CORE AUDIENCE

Design-build teams

Move from design information to construction quantities with a shared, reviewable workflow for preconstruction decisions.

04 / ADJACENT AUDIENCE

Architects & engineers

Give clients and project teams early quantity information from architectural, structural and other dimensioned drawings.

05 / ADJACENT AUDIENCE

Developers & owners

Understand project scope and feasibility quantities earlier, before detailed pricing or a construction commitment.

06 / ADJACENT AUDIENCE

Project managers & consultants

Check drawing-led quantities, clarify assumptions and carry an editable quantity workbook into the next conversation.

Example output

From this drawing…

A dimensioned PDF, DWG or DXF floor plan becomes a structured quantity sheet that can be reviewed, edited and carried into an estimating or quantity surveying workflow.

FAQ

Answers about construction takeoff and BOQ workflows.

Everything you need to know about access, drawing formats, quantity takeoff, review and the preliminary bill of quantities workflow.

What is a construction quantity takeoff?

A construction quantity takeoff is the process of measuring areas, lengths, counts and other building elements from project drawings so a team can understand scope, prepare a budget or build a bill of quantities.

Who is apstrog for?

apstrog is designed for estimators, quantity surveyors, general and specialty contractors, design-build teams, architects, engineers, developers, owners, project managers and construction consultants who work from drawings.

How do I get early access?

Request early access with your name, email and role. You can then optionally share your workflow and a sample drawing. We will contact you as suitable pilot places become available.

What drawing formats does it support?

apstrog is built for properly dimensioned PDF, DWG and DXF construction drawings, including architectural plans and CAD drawing workflows.

Can it create a quantity takeoff from a PDF or CAD drawing?

Yes. apstrog is designed to interpret explicit dimensions, annotations and geometry in properly dimensioned PDF, DWG and DXF drawings and turn the result into structured quantities for review.

Does it produce a complete priced estimate?

apstrog turns drawings into structured, editable preliminary BOQs. Pricing and rate-library features are separate from the quantity workflow.

Will it replace a quantity surveyor or estimator?

No. apstrog is designed to reduce repetitive drawing measurement and quantity preparation. Professional review remains important for construction, contractual and commercial decisions.

How does it measure drawings?

apstrog interprets explicit drawing dimensions, annotations and geometry and connects them to measurable construction elements, rather than relying only on visual scale estimation.

What if a drawing is incomplete?

Quantities requiring missing information may be flagged for review rather than silently estimated.

Will I be able to edit the BOQ?

Yes. Outputs remain editable and can be exported to formats such as Excel so your team can continue its estimating or quantity surveying workflow.

How much will it cost?

Early access is free. Pricing for broader access will be shared before public launch.
