Exercise (5.1) A civil engineer involved in construction requires 4800, 5810, and 5690 m³ of sand, fine gravel, and coarse gravel, respectively, for a building project. These materials can be obtained from three pits. The composition of these pits is: Fine Coarse Sand Gravel Gravel % % Pit 1 52 30 18 Pit 2 20 50 30 Pit 3 25 20 55 by Gauss elimination How many cubic meters must be taken from each pit in order to meet the engineer's needs?

A project to move packed earth requires you to decide whether to usea dozer/scraper operation or excavator/truck operation. Determinethe most economical operation based on the dozer/scraper operationestimated at $1.25/cy. All equipment carries a rated heaped capacity, hasa fill factor of 100%, and works 45-min hours. Excavator costs $95/hr（including operator), cycle time is 0.28 min, and bucket heaped capacityis 5.0 cy. Truck costs $150/hr.(including operator), dump time is 0.5 min（maneuver, dump, turn), heaped capacity is 31.7 cy, and 12 trucks areavailable for the project.Hauling equipment operates in one directionfrom A to B to C and finally to D.

Under a unit-price contract with a 25 percent guarantee requirement of all unit prices quoted, the engineer’s estimate of earthwork quantities totals 9,270 cubic meters. If the actual quantities measured in the field for paypurposes total 10,650 cubic meters, is a change order justified for the quantity change?

1. for a project your company is a Haul away 350 bank cubic yards of sand. If the sand has a swell of 12% how many loose cubic yards of sand will need to be hard how many truckloads are required a Holden sent off so that each truck and haul 12 loose cubic yards? 2. if 750 compacted cubic yards of in-place oil is required for a project how many loads of import will be required. The important material has a swell of 30% in a 15% shrinkage factor the trucks can haul 10 loose cubic yards.

On January 1, 1978, the purchasing engineer of a Cement Co. purchased a new machine at a cost of140,000. Depreciation has been computed by the straight-line method based on an estimated useful lifeof five years and residual scrap value of 12,800. On January 2, 1981, extraordinary repairs (which werealmost equivalent to a rebuilding of machinery) were performed at a cost of 30,400. Because of thethorough going nature of these repairs, the normal life of the machinery was extended materially. Therevised estimate of useful life was four years from January 1, 1981.Determine the annual provision for depreciation for the years 1978 to 1980 and the adjusted provisionfor depreciation on December 31, 1981. Assume payment in cash for the machine and extraordinaryrepairs. construct a straight line method
