Shown below is a trapezoidal area which will be excavated and used as borrow pit. It has been laid out by lines at right angles to each other at given distances. The elevation of each grade intersection is as indicated in meters. It is desired to excavate the same to elevation 50m. Determine the volume of excavation in cubic meters by using: 1) unit volume method 2) parallel section method

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.
