Problem 1
The labor and material cost for a riprapping work is as follows:
Labor:
Materials: (For every 1 cu. m. volume)
1 Foreman @ P500.00 per hour
Cement = 3 bags @ P150.00 per bag
1 Skilled Worker @ p40.00 per hour
Sand = 0.25 cu. m. @P300.00 per cu. m.
5 Unskilled Workers @ P35.00 per hour
Boulder = 1 cu. m. @P250.00 per cu. m.
The accomplishment of the above laborers is 0.45 cubic meter per hour. Profit,
overhead and miscellaneous expenses is 30% of the labor and material cost. Value
Added Tax (VAT) is 10% of the labor cost.
a) Determine the labor cost per cubic meter.
b) Determine the cost of materials per cubic meter.
c) Give the total cost of riprapping per cubic meter.

There is a continuing requirement for stand by electrical power at a public utilityservice facility. Alternative A involves an initial cost of $72,000, a 3-year useful life.and an annual cost of $2,200 the first year and increasing $300 per year thereafterand a net salvage value of $8,400 at the end of the useful life. Alternative B has aninitial cost of $90,000. a six-year useful life, and annual cost of 2,100 and a netsalvage value of $13,000. The current interest rate is 10% annually. Whatalternative are you going to recommend if you use co terminated (study period is 3 years, epsilon = 10%) assumption?
how did you get 1.025 for solving the pre consolidation?

- Calculate the cost per cubic yard to place concrete using each of the alternatives described. The work in both cases consists of placing 140 cubic yards of concrete in footings. a. Using a crane and bucket at a price of $225 per hour, including an operator, with a crew consisting of 6 laborers, a cement finisher, and a foreman. The concrete will be placed in 7 hours using this setup, and transportation of the crane costs $390. b.
