Advances in 3D laser scanning technology, and recent implementation in the architecture, engineering and construction (AEC) industry, has improved the way projects are approached. Point cloud data, derived from 3D Laser scanning technology, is used to generate building information models (BIM) with detailed 3D information for as-built conditions. By using this 3D data, designers can better understand current infrastructure and building conditions in real-time.
Integration of 3D scan point cloud data with current as-built conditions in a BIM model increases the possibilities for building deconstruction prior a renovation process.Understanding the specific as-built conditions and components of a building is key before the schematic design stage. 3D laser scanning and point cloud data in BIM software can provide a complete set of information of the architectural, structural and MEP systems of a building with exact properties, dimensions, and location. 
Benefits of Scan to Building Information Model (BIM) for the AEC Industry
Combining 3D laser scanning technology into building information model software brings significant benefits to the BIM process. By generating intelligent data and integrating it into a BIM model, architectural and engineering firms can optimize the design process and increase in workflow efficiency, in addition to reducing the errors, cost and time needed for project completion.
Scan to BIM services eliminates many of the uncertainties found during the pre-design phase reducing potential issues in the construction phase of a project.
Generating existing conditions without using 3D data as a guide increases time, costs and potential for error. Data generation from point cloud data using 3D scanning technology is accurate and reliable, which is why scan to BIM services contribute in the productivity and efficiency of renovation projects. This technology will continue to support the AEC industry’s growth. =
Laser Scanning Technology (or LiDAR) and Scan to BIM in the AEC Market
As 3D technology advances, 3D laser scanning has become increasingly influential. The architectural and construction community has had a long-running engagement from using this expertise to obtain high-resolution 3D point cloud data and accurate scan to BIM models. This information is essential to better understand the specific conditions of a project and to later integrate it into the internal BIM model for project design and construction.
There is a large variety of applications of 3D laser scanning technology within the AEC market. It ranges from detailed interior and exterior scanning for heritage building conservation, accurate measurements of glass partition framing systems, structural systems documentation, clash and clearance detection for MEP systems, as-built drawings for renovation projects, to checks during construction for concrete forming and so on.
