The model knows
the quantities.
So should the BOQ.

Upload a Revit file. AI reads the BIM model, extracts the quantities — concrete cum, steel MT, masonry, plaster, MEP — and turns them into a structured BOQ. As work executes on site, the model lights up element by element, floor by floor. The site engineer reports work done; the model reflects it. Visual progress against the digital twin.

§ 01
The flow
From design model · to live progress

Three steps.
One digital twin.

Upload the Revit model. The system reads every element — every column, every slab, every wall, every duct — and extracts a structured BOQ. As work executes on site, the model becomes the progress dashboard. The same screen shows what's planned, what's done, where you are.

The pillars
Three deep-dives · what BIM Revit BOQ does

Upload. Extract. Light up.

First pillar: what happens at upload. Second pillar: what extraction produces and how it slots into the spine. Third pillar: how the model becomes the progress dashboard.
Pillar · 01 · Upload

The model is the source of truth.

The architect publishes the Revit file. The structural consultant publishes theirs. The MEP consultant publishes theirs. Three federated models, one tower. Upload them — independently or as a coordinated set. The system parses every element type, walks the discipline hierarchy, captures the parameters that matter (material grade, dimensions, levels). Open standards: Revit native, IFC, NWD.

From elements to a structured BOQ.

An element in the model is a wall with a length, a thickness, a material grade. The system aggregates: every wall of M30 grade becomes part of the M30 concrete BOQ line. Steel reinforcement is computed from member sizes via grade-aware co-efficients. MEP is captured by run length, fitting count, fixture type. Each BOQ line carries back-references — *which elements in the model contributed to this 6,800 cum?* You can drill down to the source.

The model becomes the progress dashboard.

Site engineer reports work done — slab F5 cast, columns F5-F6 done, brickwork F3 in progress. The system finds the matching elements in the model and changes their colour. Done is green. Active is gold. Planned is grey. Anyone — site, project manager, CFO, board — opens the model and instantly sees: how many floors are done, what's currently active, where the laggards are. Variance against plan shows up as red elements. The CFO no longer asks for a status meeting.

Outcome
Why this is worth deploying

The model that
pays for itself.

Manually preparing a BOQ from drawings takes a quantity surveyor weeks. BIM Revit BOQ does it in minutes. The accuracy gain alone — fewer missed elements, fewer measurement errors — typically saves more than the deployment cost on the first project.
▸ The case for BIM

Faster BOQ. Fewer surprises.
Live progress.

90% Faster BOQ preparation · weeks → minutes
12k+ Elements per tower · all extracted · all tagged
1screen Site, project, CFO, board · same view of progress

Where to go next.

BIM Revit BOQ feeds the spine — the BOQ it extracts becomes the BOQ that drives Project Engineering. The drawing transmittal flow uses the same federated model uploads. AI Scan is the other AI tool in the family.
The board used to ask 'how is Tower B going?' and we'd schedule a status call. Now they open the model on their phone — eight floors green, slab F5 gold, brickwork F6 red — and they know exactly what they need to ask. The model is the meeting. And our QS team prepares BOQs for new towers in three days instead of three weeks.

30 minutes. Bring a Revit file from one of your projects. We'll upload it, extract the BOQ live, and walk through the 3D progress dashboard. You'll see what your QS team would do with this on day one — and how the same screen serves the site, the project manager, and the board.
