Removal of concrete foundations, slabs and roads on a 30 acre site, the previous South Plant Smelter, to make way for a future Business Park. Following removal, material was crushed and placed as site fill to establish required grades. Site required the installation of a retention pond, grading and seeding for future development.
Our project team worked with Alcoa project managers, safety department and site manager to develop an approach to complete the work in a timeframe of only eleven months.
Trifecta’s plan included:
- Excavate and stockpile soil to be used as topsoil once crushed concrete had been placed, eliminating the need for topsoil import.
- Remove, crush and place existing concrete for site fill, eliminating the need for fill material import.
- Installation of detention pond and modify existing storm sewer system to provide proper drainage and storm water retention.
Equipment:
- Multiple excavators equipped with a bucket and thumb
- Multiple excavators equipped with hydraulic hammers
- Mobile crusher
- Off road haul trucks and dozers
