CALGARY AIRPORT DEVELOPMENT - CALGARY, ALBERTA
In 2011, the Calgary Airport Authority underwent the largest expansion in its history including a new 14,000 foot runway, associated taxiways, as well as an aircraft apron and other applicable infrastructure. Rough grading of the site was carried out by Broda Group as the earthworks general contractor. Excavation work in preparation for construction involved the removal of 10,000,000 m3 of material and backfill/subgrade preparation for the new infrastructure. This work also included approximately 14km of ditch/canal excavation for the storm water retention system and the mining of a 1.8 km long tunnel.
