Solved in 2 steps
- Explain your understanding of the following general construction matters:2.1 What does ‘time-barred’ mean? In your explanation you should provide a general introduction, followed by atleast three (3) examples of the most important periods in construction work where time-barring would occur (12)Explain the Meyerhof reduction factor method ?Describe the Standard Model of Consolidation
- discuss in detail, each of the factors affecting haulers productivity.How soil is compressed below the pile toe and dragged down along the sides of a pile during installation?What do you mean by Keep the horizontal width of the excavation to make sure that work activity would not vibrate the soil while workers are in the trench? Cite some examples as well.
- Briefly discuss the advantages of preloading methods?Why is it sometimes resorted to digging more than one well at the work site when the groundwater level is to be reduced?Calculate the tender rate per bank cubic meter for an excavation of a trench given:• Hire cost = R800 per hour, including owning costs• Fuel Consumption = 4 l/h of Diesel fuel at R15/h• Scoop capacity is 35 banks m3/h• Operating factor = 0.8• Dimensions of trench: 10m x 3m• Operator earns R40.41/h• Head office overheads = 30%• Site overheads = 20%• Profit margin factor = 0.045• Contractor has perceived no risk on this operation
