Estimate the direct cost to install, using cut and cover methods, 1 mile of ductile iron pipe for a water service line. The pipe will be 8” in diameter and use push-on connections. Install four gate valves, which require 1 hour each for a common laborer, skilled laborer, and crane operator. The cost of testing and sterilizing the line is $2,000. The truck crane rental is $750/day and has no mobilization costs. Work is being done during an 8 hour/day shift. Disregard the cost of excavating, placing bedding material, and backfilling the trench as it will be done by others. Cost of materials and labor are:
