EnTech uses a variety of instruments, including LiDAR technology (also called laser scanning or 3D scanning), to survey buildings and environments. The data from these surveys is used to create precise 3D representations called point clouds, which form the basis of as-built models and 3D BIM models. Our teams have scanned over 1 million square feet of facilities and infrastructure in the New York metropolitan area, across hundreds of projects.
EnTech’s VDC engineers use best-in-class technology, selecting the most appropriate equipment for each project, from terrestrial laser scanners to drone-mounted cameras.
For this project, EnTech first used a LiDAR scanner to capture the exterior of a facility (A) and flew a drone to use aerial photogrammetry to capture the roof components (B). The team then selected a different laser scanner better suited to short distances to scan the building interior (C). Together, these tools generated a point cloud (D), from which the team developed a 3D BIM combining multiple building systems (E–F).
Our field teams use a range of reality capture software tools to assess existing spaces, determine optimal scanning locations, and verify scan completeness.
