4. Levels were taken at every 40 m along a piece of ground. The following observations were recorded: Distance(m) 0 40 80 120 160 200 105.0 114.2 123.6 128.0 130.20 125.60 Elevation (m) A cutting is to be made for a line of uniform gradient through the first and the last point. Determine its gradient. Calculate the volume of excavation if the formation width is 8.0 m, with side slopes in cutting being 1.5:1, and the natural ground slope is 10:1.

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.
