  • Managing huge volumes of scanned data files and working with them
  • Rectifying the inconsistencies in scanned data and recreating the missing scanned data using engineering assumptions
  • Completion of the project – that demanded complex modeling, complete with architectural and structural details, within a very tight deadline


All the scanned data in .pcg format was imported into Revit and surfaces were restructured, to create an intelligent BIM with LOD 300 with architectural and structure disciplines.

  • 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
  • Information rich, intelligent BIM, provided a thorough documentation of the “as built structure”
  • This further improved the operations and management of the educational center

Engineering Solution: 

  • The scanned data was extremely heavy. It consisted of nearly 300 scans and several photometric images
  • All these .pcg files were was imported into Revit and divided into sections to set up a model file
  • A team of modelers worked in shifts to restructure the entire building with all the architectural and structural details
  • 10mm accuracy modeling was done and within 24 days, an intelligent BIM with LOD 300 was created
  •  Scanned data for some parts of the building was missing and the one available had a lot of inconsistencies
  • At this point, the team communicated with the client and restructured the missing parts based on engineering assumptions and using the reference images
