CAD to BIM conversion — your DWG and PDF archive as a working Revit model

What we start from

Anything that exists. Vector DWG archives, exported PDFs, raster scans of paper prints, photographs of drawings pinned to a wall, an incomplete measured survey, or some combination of all of them. You do not need to sort the material before sending it — sorting it is part of the job.

Where the effort actually goes

The modelling is the straightforward part. The work that decides whether the result is usable is reconciliation: two archive drawings of the same floor that disagree by 150 mm, a section that does not match the plan it was cut from, a level datum that changed between drawing packages without anyone renaming the file. We resolve those conflicts, and where a conflict cannot be resolved from the material we flag it in writing rather than modelling a guess and letting you discover it on site.

Twenty-three years of building design and construction is what makes that judgement possible. Knowing which of two contradictory drawings is likely to be the built condition is not a Revit skill.

What you get

A Revit model at LOD 200–350 as agreed, built in your template, with levels, grids and wall types set up so the model carries the project rather than illustrating it. Plans, sections and elevations are generated from the model and coordinated, not drafted independently. Where accuracy is limited by the source material, the limits are documented in a short accompanying note.

Accuracy and what it depends on

A conversion is only as accurate as what it was converted from. From dimensioned vector DWG we work to the dimensions given. From scans and PDFs we work to the stated dimensions first and scaled geometry second, and we say so. If a site visit or a fresh measured survey is what the project actually needs, we will tell you that instead of selling a model built on unreliable input.
