PMI constructed two new hazardous waste landfill cells. The scope of work included a site-specific health and safety plan, traffic control plan, stormwater pollution prevention plan, over 100,000 cubic yards of earthwork and clay liner, compaction and permeability testing, a dual-layered HDPE liner system, 40,000 tons of gravel and over 6,000 feet of HDPE piping. A 3D model and GPS equipment helped to complete this time-sensitive project 30 days ahead of schedule.
