Concept explainers

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.

A concrete dam of 17.5 m base width retains 5 m of water. A sheet pile cut-off is provided at the upstream end of the base of the dam upto a depth of 8 m. The base of the dam is 1.5 m below ground surface and the pervious foundation extends to a depth of 14 m, below which is an impervious stratum. Draw the flow net and compute the seepage flow below the dam per metre length of dam, if the coefficient of permeability is 2 x 10-3 cm/s. compute the uplift pressure along the base of the dam and the exit gradient.
The Town of Jackson Engineering Department has an earthen dike through which a circular concrete culvert has been constructed to convey storm water from one side of the dike to the other side of the dike. The circular concrete culvert has a free outfall. The culvert is 60 feet long on a 2.00 % slope and is 30 inches in diameter. The culvert entrance will project from the embankment. Use an orifice coefficient (Co) of 0.62 for a sharp-edged entrance. Create a rating table that correlates the culvert discharge to the depth of the headwater, from 3 feet to 6 feet in 0.25 feet increments. The Engineering Department would like to know the culvert discharge rate based on the depth of the headwater so that they can conduct long-term planning (development, infrastructure improvements, open space, etc.) on the upstream and downstream sides of the dike. Cite any references used.
