Blue Mountain Cabin
Jack and Jill Smith have just retired and want to build a small, basic cabin in
the Blue Mountains of Vermont. They have hired Daryl Hannah as the
general contractor for the project. She has assembled a team of three
workers to complete the project: Tom, Dick, and Harry. Daryl has negotiated
a cost-plus contract with the Smiths whereby she will receive 15 percent
beyond the cost of labor and materials.
Before they sign the contract the Smiths want an estimate of how much the
project is likely to cost and how long it will take.
Darryl has estimated that the cost for materials, permits, etc., will total
$40,000. She wants to determine labor costs as well as how long the project
will take. This is one of several projects Daryl is managing, and other than
occasionally helping out, her role is strictly limited to supervising. She has
devised the following master plan and assignments.
Note that Dick is the only skilled plumber in the group while Harry is the
only skilled electrician. Tom is a general carpenter and can assist them with
their work. Dick and Harry each get paid $300 a day while Tom gets paid
$200 per day.
Darryl has negotiated a 10 percent management reserve to deal with
unexpected problems. Unused funds will be returned to the Smiths.
