Chicago Old Post Office

Epic Scan conducted 3D laser scanning and documentation of the Old Chicago Post Office. Our client needed point cloud data, a building information model (BIM), a 3D animation and virtual site access (VSA) of the project site. The 3D information will be used to help designers with the renovation of the post office.
