Means and Methods:

All rock was blasted using an ammonium nitrate compound. Each boring hole was drilled 6 ft. on center and to a depth of 12 ft. Once rock was blasted, AMPCO utilized a D11 Dozer with a ripper to loosen the fill material and separate any granite that could not be picked up by the scraper. Once material was separated, a fleet of 657 (8 EA) Scrapers, along with the proper support equipment, moved approximately 250,000 CY of material to complete the building pad section. AMPCO effectively assisted ownership in the design-build process of the civil portion of the work to effectively manage the blasting and the processing of the oversized rock making this project financially feasible for ownership.

Challenges Faced:

AMPCO assisted ownership to turn what industrial developers thought was financially unbuildable into a well-managed, financially-effective site. In addition, AMPCO was able to effectively manage all unforeseen subsurface conditions, and unprecedented rain events, while maintaining the project schedule
