The following data are extracted from a pipe-layıng conuacl. • Concrete pipe diameter: inside 300mm, outside 334mm • Overall pipe length = 925m • Width of the trench = 750mm %3D %3D Trench depths are: 1.5m for 631m reach, 2m for 274m reach and 2.5m for 20m reach Calculate the total cost and cost for each depth to a contractor of excavation, planking and strutt laying pipes, surrounding concrete as shown in the figure below and backfilling using the follow data. Suitable material Concrete class E 150mm min. Cover 334mm may be formed Thorizaontal surface 100mm Width of trench = 750mm Labour and plant for pipe-laying (up to 300mm diameter): One JCB 3C excavator @ $25/hr, Small plant, pumps and compactor @ $3/7/hr, One pipe-layer @ $15/hr, • Two labourers @ $10/hr each Assume a working week is 50hrs. Also, assume an average output of 50 linear meteres of pipe laid per week, the output vaerying with the depth of trench. The output indcludes axcavating, trimming. pipe laing, concreting and backfilling.
