A Construction Project A maintenance building construction project also includes an external electrical generator and water tank. The first activity is to excavate which requires two weeks. Following excavation, the maintenance building will be built, and then both the generator and the water tank can be installed. These three activities, building, generator, and tank, require six, four, and two weeks, respectively. Once this set of three activities is completed, the tank and generator can be connected to the building, an activity that requires five weeks. After the maintenance building is built, maintenance equipment can also be installed inside the building and this activity takes four weeks. Painting the maintenance building is also required, following its construction, and this takes three weeks. Finally, after the maintenance equipment is installed and the connection is completed, it will take two weeks to inspect the new maintenance facility. Suppose the costs of the activities are: Activity Excavate Construct Building Install Generator Install Tank Connect Install Maintenance Paint Inspect Cost ($1000s) $50 $150 $120 $50 $40 $30 $30 $10 Suppose 5 weeks of the project have elapsed. The following work has occurred: Activity Percent Complete Actual Cost (1000s) Excavate $60 Construct Building $75 $100 $50 Install Generator Install Tank What is the estimated cost at completion and what percentage is this over or under budget? $536,000 and 10% over budget $499,000 and 12% over budget $499,000 and 4% over budget 100% 50% 75% 80% $480,000 and not over budget $429,000 and 12% under budget None of the answers are correct.
