A beam 10 m long is simply supported 1 meter from each end. It is made of two C380x50 channels riveted back to back and used with the webs vertical. Determine the total uniformly distributed load that can be carried along its entire length without exceeding a flexural stress of 120 MPa. Properties of c380x50 channel (vertical web): Area: 6430 mm2 Depth: 381 mm Width: 86 mm Thickness: 16.5 mm Web Thickness: 10.2 mm Ix = 131 x 106 mm4 Iy = 3.39 x 106 mm4

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.
