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.

An excavation is rapidly made on site as depicted in the Figure below. The soil wedge above the critical slip surface is divided into thirteen slices. Based on the ordinary method of slices, calculate the ratio (R/S) between the Resisting Force (R) and the Driving Force (S) for slice #3, shortly after the excavation is completed. (Acceptable tolerance = 4%). The geometry of slice #3 and the soil properties are provided in the tables below. The height of water at the middle of the slice is hw = 3.0 m. Note that the total weight of the slice is equal to the weight of the saturated soil below the water table plus the weight of the moist soil above the water table. Hint: the weight of slice #3 is 495 kN
An SPT test was conducted in a dry sand (no ground water table) with a unit weight of 18kN/m3. The drill rig used had an energy efficiency rating of 60%. The recorded blow counts were 6, 7 and 8.

ssion begins when the primary consolidation ends. B. The soil from a borrow area is excavated and used in a compacted fill for an embankment. The void ratio at the borrow area and the compacted fill are 0.96 and 0.62, respectively. What would be the volume of the excavation in the borrow area to construct 200,000 m3 of compacted fill? Q2:

Using the traditional method, determine the required depth of embedment of the piling below the bottom of the excavation to give a factor of safety of 2.0 with respect to passive resistance. M
