Construction Administration & Commissioning
Shop drawings, site reviews, deficiency tracking and commissioning, so what gets built matches what was designed and occupancy is not delayed.

Construction Administration & Commissioning questions

Yes. We carry out the field reviews required under the Ontario Building Code and issue the general conformance letters the municipality needs for occupancy and permit closure.
