Laser Scanning and BIM

In Construction, real-time quality control and early defect detection can significantly reduce cost overrun and project schedule. The current approaches for quality control on construction sites are time-consuming and ineffective since they only provide data at specific locations and times to represent the work in place. It further limits a quality manager’s ability to identify and manage defects. The solution lies in an integrated system of Building Information Modeling (BIM), Light Detection, and Ranging (LiDAR) to come up with real-time onsite quality information collecting and processing for construction quality control. Using a variety of instruments, we capture existing conditions - topography, buildings, exterior/interior spaces, and more - in highly accurate detail that allows for 2D and 3D measurement. These measurements form the basis for analysis, design, documentation, and quality control. We do this using the fastest, most accurate, non-contact instruments known, literally at light speed. We use our capture process for a project as small as a residential home or as large as an entire university campus. The data we capture can be re-used and updated without limit and is easily integrated into many different software platforms. Some of the features in this category are as follows:

• 2d and 3d digital replication
• BIM Models from LiDAR point cloud data
• As-built documentation in Revit/AutoCAD from scanned point cloud data
• Beneficial for Renovation, Refurbishment / Retrofitting of existing structures
• High accuracy/ tolerance models generated
• Tracing and surface restructuring from point cloud data
• 3D BIM models from point cloud captured by a drone
