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.

Civil Engineering Two near-surface strata of the same soft clay are to be consolidated. In one the consolidation is to be done by placement of a surcharge fill at the ground surface. In the other, the consolidation is to be effected by lowering the water table to the bottom of the clay layer and evaporation of water from the ground surface, which will cause shrinkage of the clay. The ground water table is initially at the top of the clay stratum. Show profiles of effective stress and water pressure versus depth for each stratum corresponding to the condition where the vertical effective stress is the same in each at middepth. Will the clay structure be the same in each stratum at this depth at this time? Why?
