Chapter 12, Problem 7RQ

True or False? The total machinery area for a machine is determined by identifying the floor space for each machine, machine travel, maintenance and service area requirements.

A light manufacturing firm has set up a project for develop- ing a new machine for one of its production lines. The most likely estimated cost of the project itself is $1,000,000, but the most optimistic estimate is $900,000 while the pessimists predict a project cost of $1,200,000. The real problem is that even if the project costs are within those limits, if the project itself plus its implementation costs exceed $1,425,000, the project will not meet the firm’s NPV hurdle. There are four cost categories involved in adding the prospective new machine to the production line: (1) engineering labor cost, (2) nonengineering labor cost, (3) assorted material cost, and (4) production line downtime cost. The engineering labor requirement has been estimated to be 600 hours, plus or minus 15 percent at a cost of $80 per hour. The nonengineering labor requirement is esti- mated to be 1,500 hours, but could be as low as 1,200 hours or as high as 2,200 hours at a cost of $35 per hour. Assorted…

Paint Y costs P1000 per gallon and can be applied at a rate of 125 ft² per hour. If the area to be painted is 100ft2  and  the painter is paid P50 per hour, how much is labor cost per hour?

Given the table below, calculate the total cost for all the items needed. What would be the total estimate with a 15 percent contingency? If a 10 percent reserve is added, what would be the total estimate? Items Cost/Unit Quantity Wheel $500 12 Bearing $25 400 Clamp $5 40 Nozzle $7 30 Nut $2 40 Caster  $55 120

A labor crew for placing concrete consists of one labor foreman at $27.69 per hour, one cement finisher at $29.30 per hour, 4 laborers at $24.45 per hour each, and one equipment operator at $34.3 per hour. Such a crew, called a C20 crew, can place 156 cubic yards of concrete per 8-hour day. Determine the cost of C20 crew per cubic yard of concrete. The cost of C20 crew per cubic yard of concrete is determined to be $
