UVIC
Stone Design is grinding the floors, soon to be squash courts, at the new CARSA building at UVIC. Campbell Construction brought in the skilled Stone Design crew to help bring the squash courts to a tolerance of 3mm over 3 M. By shooting in the elevations of the concrete slab, the crew see the high points needed to be ground to tolerance.
