Project Objective
Convert 3D scanned images into intelligent BIM with LOD 300 with architectural and structure disciplines of an UK based educational center
Technology/Software Used
Revit, Recap
One of the most reputed surveying company based in London, UK, approached Hi-Tech for its BIM requirements. The client had surveyed an educational center and wanted to convert the point cloud data to BIM. Almost 300 scans were done to capture every section of the building, .pcg input files were provided and modeling architecture and structure disciplines with 10mm accuracy with an LOD 300 was requested.
Challenges:
1: Managing huge volumes of scanned data files and working with them
2:Rectifying the inconsistencies in scanned data and recreating the missing scanned data using engineering assumptions
3: Completion of the project – that demanded complex modeling, complete with architectural and structural details, within a very tight deadline
Engineering Solution:
1: The scanned data was extremely heavy. It consisted of nearly 300 scans and several photometric images
2: All these .pcg files were was imported into Revit and divided into sections to set up a model file
3: A team of modelers worked in shifts to restructure the entire building with all the architectural and structural details
4: 10mm accuracy modeling was done and within 24 days, an intelligent BIM with LOD 300 was created
4.1 : Scanned data for some parts of the building was missing and the one available had a lot of inconsistencies
4.2: At this point, the team communicated with the client and restructured the missing parts based on engineering assumptions and using the reference images
Benefits:
1: Renovation for a major section of the educational facility became easy, the basic structure was retained and the client saved around 20% costs on renovation due to the availability of well documented information
2: Information rich, intelligent BIM, provided a thorough documentation of the “as built structure”
3: This further improved the operations and management of the educational center
