Measuring site work, Excavation and Piling

Bid drawings typically include very little material about the precise requirements of site work operations, measuring site work and excavation work differs from measuring most other works on a construction project. The actual site work conditions are not provided and also the dimensions of the excavations are not known during the pre-construction phase. The precise measurement of the excavation and backfill of the earth material and topsoil is important for a contractor to decide upon the total cost required for the process. All the works should be carried out under OSHA (Occupational Safety and Health Administration) standards to ensure the safety of the workers.

Initially, the water table is 2m below the ground surface and hydrostatic condition exists throughout the soil profile. Before constructing a structure on this site, the organic silt is preconsolidated by rapidly lowering the water table by 6m (to 8m below the ground surface) and simultaneously pumping from the gravel layer at such rate that the piezometric level in the gravel is lowered to the bottom of the organic silt.
