Upload dimensioned plans
Start with architectural floor plans and other properly dimensioned PDF, DWG or DXF construction drawings.
Construction takeoff software
Turn construction drawings into reviewable quantities.
apstrog helps contractors, estimators and quantity surveyors move from dimensioned PDF, DWG and DXF plans to structured quantity takeoffs and editable preliminary BOQs.

A practical digital takeoff workflow
Keep the measurement work connected to the drawing.
A useful construction takeoff is more than a list of numbers. Your team needs to know what was measured, where it came from and what still needs professional review. apstrog is designed around that handoff.
Interpret drawing evidence
Dimensions, annotations and drawing geometry are associated with measurable building elements such as walls, rooms and openings.
Review and export quantities
Confirm or correct the extracted quantities, then carry an editable quantity workbook or preliminary BOQ into your estimating workflow.
Quantity takeoff coverage
Measure the scope your estimate depends on.
Use the drawing-led workflow for the common area, linear and count quantities that feed preliminary estimates, budgets and bills of quantities.
Learn about quantity takeoff from drawingsAreas
Room areas, gross floor areas, floor finishes, ceiling finishes and painting areas.
Lengths
Internal and external wall lengths, partitions, skirting, plaster, render and other linear work.
Counts
Doors, windows, openings and other repeated elements shown on the plan.
Structured output
Organise quantities into a reviewable, editable preliminary bill of quantities for the next stage of pricing.
Built for takeoff-led teams
A construction quantity workflow for the people pricing and planning work.
The strongest fit is with teams that repeatedly receive drawing sets and need usable quantities before a bid, budget, procurement decision or construction conversation.
Estimators & quantity surveyors
Reduce repetitive measurement and keep more time for scope review, pricing, assumptions and commercial judgement.
General contractors
Screen opportunities and prepare preliminary quantities from the plan set before committing more estimating time.
Specialty contractors & subcontractors
Focus a takeoff on the trade scope you need to price and carry the result into bid preparation.
Design-build & preconstruction teams
Move from design information to early construction quantities with a clear review point for the wider team.
What apstrog does not claim:It does not replace a qualified estimator or quantity surveyor, and it does not turn a preliminary quantity takeoff into a complete priced estimate without your rates, assumptions and professional review.
Construction takeoff FAQ
Questions before you change your workflow.
Understand where drawing takeoff software fits alongside estimating, quantity surveying and construction planning.
What is construction takeoff software?
Construction takeoff software helps a team measure and organise the quantities shown in project drawings. It can support areas, lengths and counts used for estimating, budgeting, procurement and bill of quantities preparation.
Who uses construction takeoff software?
General contractors, specialty contractors, subcontractors, estimators, quantity surveyors, design-build teams and preconstruction professionals use takeoff software to turn drawing information into quantities they can review and price.
Can apstrog create a takeoff from PDF and CAD drawings?
apstrog is built for properly dimensioned PDF, DWG and DXF construction drawings, including architectural plans. It interprets explicit dimensions, annotations and geometry and keeps a review point before export.
Does apstrog replace estimating or quantity surveying software?
No. apstrog focuses on drawing measurement and preliminary quantity preparation. The output is an editable quantity sheet or preliminary BOQ that can move into your existing estimating, pricing or quantity surveying workflow.
Are quantities reviewable before they are exported?
Yes. apstrog is designed to connect quantities to source drawing information so your team can confirm or correct measurements before exporting an editable workbook.
