To avoid having to produce 3,600 sets of drawings, the piles were modelled as “coarse” geometric items in Revit and Navisworks, with simple place holder information for the pile number, location coordinates, direction and length.
This information was synced to BIMEye, where foundation contractor, Skanska, input detailed text information on each pile, covering 80 separate parameters needed by the structural engineer, ELU Konsult, plus 30 parameters for its own use. The software syncs the data back to the Revit and Navisworks models to give users real time access to all BIMEye information with the click of a mouse.
As each batch of 50 piles is drilled and installed, Skanska feeds as-built data back into BIMEye to enable the structural engineer to check progress against the design. As-built parameters include final X, Y, Z coordinates, depth, the number of extra steel sections that had to be welded, and technical data on ground pressure.
Progress is checked in BIMeye
“Using BIMeye we didn’t need to produce any drawings for the piling,” says Johan Stribeck, area business manager for BIM and VR at Tikab. “Although we could have recorded the data in Excel spreadsheets, the information would not have been accessible in all the BIM models. It means we can have one team entering information online, without requiring any knowledge of Revit, while the design team still has all the information available at its fingertips.”
According to Stribeck, using BIMeye eliminated the possibility of information “gaps”, where information in drawings is sometimes not entered into spreadsheets. In addition, having one source of data available in several locations – in the database, in Revit models and in Navisworks for coordination – guaranteed the quality and accuracy of information.
With the first 50 piles now in place, the process is running as planned, but it won’t be until 2022, when all 3,600 have been installed, that the real impact of BIMeye can be fully assessed.
