J.F. White's work on this project entailed the excavation of the building foundation for the Harvard Graduate Housing Building inside a perimeter slurry wall. The foundation was approximately 90,000 square feet by 40-feet deep. In addition, J. F. White installed and later removed a two level internal bracing system.
The site was a DEP listed site and the project team had to dispose of 12 different classifications of soil, which required either a Bill of Lading or Material Shipping Record. There were almost 8,000 truckloads of material to dispose of and track. Contamination was a problem on the site.
One excavated material, classified a hazardous waste, required treatment prior to disposal because of lead pollutants. The material was stockpiled in 1-foot increments; sprayed with a MBS Slurry to neutralize it; and the process was repeated. Once the soil dried out, it was then classified for disposal in a lined in-state landfill and a RCRA landfill. |
