As-builts in an afternoon: documenting a building that has no drawings

Renovation work usually starts with a building nobody has drawings for — or drawings from 1974 that stopped being true in 1989. Producing as-builts is traditionally days of field measuring and CAD work before any design can begin.

What a scan produces

A whole-house capture is as-built documentation, immediately:

  • Dimensioned floor plans with real wall lengths and room areas
  • Wall heights per wall, including the places they change
  • Door and window locations with measured openings
  • A 3D model, exportable as USDZ, that opens in design tools
  • Photographic context if you capture in High Fidelity mode

The capture is minutes per room. What used to be the week before the project starts becomes the afternoon you first visit.

It is documentation, not a survey

The honest framing: this is as-built documentation at the accuracy a renovation design and a bid need — roughly an inch at room scale. It is not a surveyor's control network, and it is not the right basis for a structural drawing or a property-line dispute. Use it for design, scope, and pricing; bring a surveyor for the things a surveyor is for.

Why it changes the sequence

The usual order is measure, draw, design, price. When measuring collapses into the first visit, you can price the project while the owner is still in the room, and the designer gets a model instead of a sketch. Nothing downstream waits on a field-measuring trip.

For the building's own sake

Property managers, facilities teams, and landlords benefit from documentation that simply exists. Unit layouts, areas, and openings captured once are the baseline for every future turn, bid, and lease listing.

Hand it off cleanly

USDZ into SketchUp or Blender, a shared model for people who just need to look, and plan dimensions for whoever is pricing.

A building without drawings is not undocumented. It just has not been walked with the right tool yet.
