3D & take-off
Generate a specification and a take-off from a 3D model
What if drawing the project was enough to write part of the specification and produce the take-off? That is the principle of model-driven written documents: the model becomes the project’s source of truth.
The model as a single source of truth
In a classic approach, the model, the specification and the take-off are produced in separate tools. Every change must be carried over everywhere — hence the omissions and diverging versions.
By linking the model to the written documents, a single action feeds several deliverables: you model an item of work, and both its specification article and its quantity follow.
From the model to the specification
Each modeled element is tied to a package. From that assignment, the specification pre-fills with the matching articles. You stay in control to add, edit or reorder, but you no longer start from a blank page.
From the model to the take-off
Areas, volumes and lengths are computed as you draw. The take-off is no longer a re-entry: it is derived from the geometry and the articles, then validated.
Why it is a game changer
The real gain is not 3D for its own sake, but the flow of data. Change the model, and both the take-off and the specification realign. Enter it once, everything updates — and the consultation, the comparison and the budget inherit that same data.
How to do it with BuildOS
BuildOS brings the 3D model, the specification and the take-off into a single web platform. You model the works by package, the specification pre-fills, the quantities flow up, and the whole feeds the contractor consultation.
