You get accurate floor plans for test fits across a portfolio by treating capture as one coordinated program instead of separate vendor hires — the same measured, current floor plan in every location, so test fits across markets are comparable.
Scan data for test fits must be measured, verified geometry of the space as it actually exists — accurate dimensions, true wall positions, real column locations — delivered as a curated floor plan, point cloud, or BIM produced from the capture.
Test fits go wrong most often because the existing-conditions data underneath them is inaccurate or out of date. The layout can be drawn perfectly and still be unreliable, because it inherits every error in the floor plan it was built on.
A test fit is a quick, diagrammatic layout that shows whether a tenant’s program fits a suite before a lease is signed. It is only as reliable as the existing-conditions data under it — accurate as-built floor plans are what make a test fit hold up.
