Point Cloud to BIM for International Broadcast Center

Project Objective:

Convert 3D scanned point cloud data of an international broadcast center into an information rich, intelligent BIM, with LOD - 300

Technology/Software Used: Revit, Recap

Client Company, one of the leading players in 3D laser scanning & BIM headquartered in London, UK, approached Hi-tech for surface reconstruction and conversion of scanned data of an International broadcast center into an intelligent BIM. Client conducted a survey of the 'As built structure' and derived point cloud data via laser scanning. 185 GB of scanned data was provided, and a BIM with level of detail - 300 was requested.

• The client wanted us to detect and rectify errors in the point cloud with accurate BIM modeling within 24 days.
• The total data size provided by client was about 185 GB & to work with such heavy data files was really a difficult task.
• The input files were in the form of 3D scanned images in which few of the scanned inputs were not clear & some of the building data was missing due to improper scanning, leading to complexity of resurfacing and modeling.
• The building area was large and also consisted of complex steel structure.
