During the excavation process, it was found that the site contained
a mixture of truck-sized boulders and backfill material that were
impacting critical areas. By entering this boulder graveyard into Site
Scan, PCL’s ICS team confirmed the exact volume and cost of removal
with the subcontractor.
By layering drone imagery (left) over the BIM layer (right), it was made
clear that the location of the excavation ramp would impede with the
