A big municipal utility district is considering two large-scale conduits. The first includes construction of a steel pipeline at a cost of $200 million. The pumping and other operating costs are expected to accrue to $6 million per year, increasing by 1% per year. Alternatively, a gravity flow canal can be constructed at a cost of $325 million. The O&M costs for the canal are expected to be $1million at EOY2, rising by $250,000 per year. Which conduit must be built at an interest rate of 6% if:
a) The projects are expected to last for 25 years?
b) The projects are expected to last forever?
A CU triaxial test with σc = 20 psi is performed on a sand and a deviator stress of 80 psi fails the specimen. Previous tests revealed that the effective friction angle for this sand is 35°. Calculate the pore water pressure at failure.
In the construction management, there is a lot of procurement route that are necessary and suitable for the construction industry.
