2. Determine the design strength P of an A992 W18x50 connected by bolts on plates on both flanges as shown in the figure. Bolts are 1/2-inch diameter on standard holes. Use case 2 for the shear lag factor. te: For the shear lag factor, imagine the section as two WT-sections, each with half the nominal depth and half the linear weight of the W-section. The ance of the top most part of the flange of the WT-section from the centroid of the WT-section is the value of x.) 4 in 4 in 1.8 in W18x50

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.
