A civil engineer working in a construction business needs 4800, 5810 and 5690 m³ of sand, fine gravel and coarse gravel respectively for a building project. There are three quarries where these can be bought. The compositions of these quarries are given in the table. How many m³ should be taken from each furnace to meet the engineer's requirement? Calculate using the Gauss-Seidel method. Continue your transactions until εa = 0.0004%. Note: Use at least 4 digits after the comma.

Describe about the Alternative Methods of Transporting Earth Fill.
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.

Given the following information, determine the cost of excavation, the number of loads required toremove the material and how many days it will take to complete the job.o 5225m3 of material is to be excavatedo Equipment cost is $280/houro Operator cost is $55/houro Equipment can remove 55m3/houro Assume 20% swell in soil when excavated for removal off siteo Trucks can carry 10m3o Work 10hr days
Calculate the total operation time for this construction activity if the volume of soil to be removed is 8 cu.m. (considered 33% for bulking of materials.) The speed of dumptruck is 30 kph and travel distance (round trip) from the source to disposal area vice-versa is 6 km. The bucket size of excavator is 0.50 cu.m at 0.50 min loading time, tipping time is 4 mins. a. 15.18 minutes b. 22.02 minutes c. 25.32 minutes d. 30.00 minutes
