Urban Center Site Clearing & Earthwork
Work Performed: demolition, site clearing, earthwork, excavation, brownfield
The Compuware project consisted of the removal of approximately 400,000 cubic yards of earthwork soils and site clearing which included the demolition, excavation and removal of approximately 16,000 cubic yards of existing reinforced concrete, including foundation walls, footings, grade beam, columns, slabs and other buried debris.
Site excavation was to the face of soldier piles in an earth retention system. Site demolition also included the removal of an abandoned Detroit Edison steam tunnel that included asbestos abatement procedures. In addition to the excavation of existing materials NADC was responsible for continual site dewatering and soil erosion control, dust control and the installation of new fire hydrants on the site.
Another hurdle to over come was the proximity of the Detroit People Mover and Sub-station to the excavation site. This required the submittal of a detailed construction and protection plan of existing structures prior to commencing of construction and excavation.
Additionally, NADC provided 24,000 tons of aggregate backfill over 40,000 square feet of geotextile fabric. NADC also built and maintained temporary site access roads, access ramps, lay down areas and parking areas including periodic grading, as well as the removal of all caisson spoils and ramps.
This project was completed on schedule, with limited change orders and without interference with the simultaneous steel work and ongoing building construction.
