23D / Pre-construction coordination & delivery

Giving builders back their certainty.

  • Every designer and every engineer produces drawings, and when you put it all together onsite, it can't be built.
  • Every tendering trade makes different assumptions and gives wildly different prices.

23D translates drawings into one unified building language, then compiles a 3D model with bill of materials and clash report. Can it be built? Where are the clashes? How much material to buy? All answered before breaking ground.

23D stands for 2D to 3D understanding, delivered at low cost, digitally.

How it works

Three steps.

Drawings arrive. 23D coordinates and compiles. You get certainty.

01

Send the drawings

Upload PDF, DWG, IFC, or other building files — send them as they are.

02

23D normalizes and compiles

The system translates drawings into a unified building language, then compiles the coordination model, BOM, and conflict and exception reports. Anything that needs human confirmation is flagged clearly.

03

Confirm and take the output

Resolve the few flagged ambiguities, then receive the full auditable package. Simple projects deliver directly; complex ones route through intake to align scope first.

Why 23D

You're buying pre-construction certainty.

No buzzwords. What v1 can and cannot do, we say clearly.
