AsBuilt Conditions, experts in architectural surveying, as built drawings and modeling, and 3D laser scanning. Chris Oudegeest, Principal, 916-502-5309. We used Asbuilt to digitally map the existing home in order for architectural plans to be accurate for our engineer and contractors. Here is a photo of a LIDAR 3D scanning setup to measure the exterior. Each LIDAR scan produced around 24 million data points of the area for a total of about 500 million (!) data points for the whole house. These data points were loaded into software that accurately mapped the house in a model.
