The Ghosts Of Buildings Captured By 3D Scanning

One of the most difficult aspects in any renovation or adaptive reuse project is building an accurate set of working drawings based on the as-built condition of a site. Often, construction documents do not exactly match what was built, whether due to the exigencies of building or to the simple cutting of corners. In creating as-built drawings it can be hard to tease out existing site relationships or to get dimensions from tight corners.

Scott Page Design proposes a faster and easier method for documenting existing construction: 3D scanning. Using the reflectivity of objects to be documented, the 3D scanner creates a point cloud which can then be inserted into a 3D model. One potential drawback to this technique, however, is that the scanner cannot see through objects but only scans what can be seen from the position of the scanner. However, various scans of the same space can be assembled to create a more complete picture.
