Brent is considering a number of possible alternatives to reduce the overall length of the project. Will any of these alternatives help him?

A$.$ Ask the contractor to provide additional technicians to reduce the time required to complete electrical and pneumatic construction by two weeks, at a cost premium of $$20,000.$

B$.$ Use two contractors for office construction instead of one. One contractor would be responsible for the office structure; the second contractor would be responsible for installation of fire alarm and safety systems, such as fire alarm, emergency lighting, and sprinklers. This approach would reduce the expected completion time for the office by three weeks but increase costs by $$30,000.$

C$.$ Ask the contractor to work overtime on Saturdays to reduce the time to complete the quality$/$supervisor pod construction by two weeks, at a cost premium of $$35,000.$

D$.$ Use a different contractor to install the anodizing line in $10$ weeks, at a cost premium of $$50,000.$
