Overview: Complete site development for new hotel and apartment site including grading, structural excavation, and site utilities.
Spotlight: Site grading required the removal and replacement of 40,000 cubic yards of contaminated material in excavations up to 28 feet deep and 18 feet below the water table.
Problem: The extent of the removal and replacement of contaminated material was not documented nor provided for in the overall project schedule whereby creating the potential of significant project delays.
Solution: Focusing first on the building footprint excavation and stabilization and developing access for both the ongoing foundation construction and import and export activities, a sequence and schedule was developed that mitigated any potential project delay.
