Project Summary

Excavation transport and disposal of contaminated soils within city works yard. The challenge on this project was to allow the city maintenance fleet to continue to work within their yard as 90% of the yard was excavated to 4.5 meters below grade. Constant movement of the active work zone, safely managing active excavation, while allowing 40 different city works yard maintenance vehicles to come and go throughout the work day to access the various city facilities and buildings. Continual excavation and backfill of the site kept the work zone as small as possible while constantly shifting the access points for the city staff, keeping vehicles and ground personnel safely out of the work zone.
