Technology Selection Criteria for Fast Paced ‘Scan-to-BIM’ Projects
This case study talks about a project where 6 partially gutted out commercial buildings with 340,000 sq. ft. of floor space, for a Silicon Valley tech giant in Mountain View, CA, were laser scanned. All the as-built conditions for these 6 buildings were captured within 2 weeks. The point clouds from these scans were used to create 3D models, containing all Architectural, Structural, and MEPF trades in less than 4 weeks. The schedule achieved was 3 times faster than the regular baseline, for projects of similar scale. This case study highlights some of the challenges faced by the reality capture team in facing the aggressive timeline, and suggests the means to overcome them in the Scan to BIM process.
This presentation will focus on the impact of correctly understanding the project scope which must comprise of, but is not limited to:
• Defining the extent of data capture
• Establishing the required level of accuracy and level of development, and how it varies with the final purpose of 3D models
• Correctly defining modeling standards, such as parameters, work sets, and more, to create an easy-to-use 3D Revit model
Lastly, it will discuss the importance of software used in the project, like Autodesk Recap Pro, Revit and Navisworks, to understand the best workflow of using them, in tandem to achieve the right accuracy and the desired time savings.
