Design a 275 ft long x 4.0 ft wide x 9.0 ft deep utility trench as a sloped excavation with no bracing following OSHA guidelines. The unconfined compressive strength of the soil is 3.2 ksf. There is not going to be vibrating equipment in the vicinity of the excavation. What OSHA soil type is this. Justify your answer.  Is benching allowed for this soil type? Explain.

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.
