True or False For the General Contractor or Project Manager the question of when to give permission to the Excavation Contractor to Backfill the excavation around the exterior perimeter of a foundation and what preparations should be made prior to Backfill are important decisions. The decision can have impacts on overall schedules and can address the request of the framing contractors to have the Backfill completed so they have far more convenient access to begin their framing of the superstructure with the back fill completed. There are several ways to prep for the Backfill and complete it. The most common is to proceed with the Backfill once the Forms are stripped and all sub-grade installs are complete, e.g. Drainage System, Exterior Insulation, Damp Proofing or Water Proofing, etc. To insure the Basement Stem Walls resist the lateral pressure of the Backfill the Excavation Contractor does not compact the Backfill Material as the Backfill proceeds.
