The Landside portion entailed demolition and removal 40,000sy of asphalt and the removal of existing utilities. Next we prepped and subgraded for the new asphalt entrance to the facility as well as the new 15,000sy customer parking lot with sidewalks, walkways, curbs and gutters. The airside portion included a sophisticated drainage system with catch basins, exfiltration trench drains, fire lines, hydrants, water main and sewer. We also laid the base material and compaction for the asphalt access to the tarmac, subgraded and compacted the building pad for the massive pre-engineered metal airport hangar, as well as a large asphalt parking lot for the airplanes. We excavated a retention area, lining it with 3,200sy of fabric liner. The most interesting and challenging portion of this project was the advanced environmental protection and fire safety systems required in today’s aviation industry. We installed a massive 10,000 gallon and 5,000 gallon underground oil and water separator. These systems will help contain and minimize any environmental spills that may occur.
