1. Develop a CPM/PERT network for Moore House Contractors and determine the probability that the contractors can complete a house within 45 days. Does it appear that the Moores might need to increase their bid to compensate for potential penalties?
2. Indicate which project activities Moore Contractors should be particularly diligent to keep on schedule by making sure workers and materials are always available. Also indicate which activities the company might shift workers from as the need arises.

Moore Housing Contractors is negotiating a deal with Countryside Realtors to build six houses in a new development. Countryside wants Moore Contractors to start in late winter or early spring when the weather begins to moderate and build through the summer into the fall. The summer months are a busy time for the realty company, and it believes it can sell the houses almost as soon as they are ready—sometimes before.
