ConstructionAI Takeoff

AI-powered fit-out and construction workflow platform

Client
Hong Kong fit-out contractor
What we built
AI takeoff, procurement and quotation platform
Result
One connected workflow from drawing to quotation
The challenge
Before this platform, a project moved through drawing review, quantity takeoff, material estimation, supplier outreach and quotation comparison as separate, manual steps. Each handoff meant re-entering the same information into a different document, spreadsheet or inbox, and a mistake made early was invisible until much later in the tender.
What we built
A platform that keeps one project record moving through takeoff, procurement and quotation, instead of five separate ones.
01Drawings
02AI takeoff
03Materials
04RFQ & vendors
05Quotation
Suppliers work inside the same system as the internal team, so a request for quotation, a clarification and a final price all live on one thread instead of scattered emails.

Project documentation moves between English, Chinese and Traditional Chinese without losing structure, which matters for a business operating day to day in Hong Kong.

How it works
The system reads a construction drawing and produces a structured takeoff for a human to check, not a number to trust blindly.

05Approved data
The quantity surveyor keeps the final call on anything the system flags as uncertain. The AI’s job is to make the first pass fast, not to make the last decision.
Validation
Takeoff accuracy is the platform’s central commercial claim, so it is checked against manually produced takeoffs rather than trusted on its own. The AI counts and measures against the drawing set; the estimator reviews anything flagged, checks complex assemblies the system is less confident on, and signs off before a number goes into a bid.

Independent testing of AI takeoff tools reports 95% to 99% accuracy on clean vector drawings, with 8% to 12% error rates on dense, heavily annotated commercial sets. This engagement’s own agreement rate is a separate figure, still to be measured against a live project set.

Security and governance
Drawings, quantities and supplier pricing are commercially sensitive. Access is scoped by role and by project, so a coordinator on one job can’t see pricing on another, and a supplier only ever sees its own quote, never a competitor’s. What reaches an AI model is limited to the specific document being analyzed in that moment, not a project’s stored history.
The impact
Connected workflow
5 stages, one record
Vendor communication
One thread per RFQ
Language support
English, Chinese & Traditional Chinese
Why it matters
Construction AI earns its place when it’s embedded in how a project actually runs, not bolted on as a chatbot beside it. A system that turns a drawing into a checked number, and that number into a quotation, is worth more than one that just answers questions about the drawing.
