Q |
A project to build a new bridge seems to be going very well since the project is well ahead of schedule and costs seem to be running very low. A major milestone has been reached where the first two activities have been totally completed and the third activity is 60% complete. The planners were only expecting to be 50% through the third activity at this time. The first activity involves prepping the site for the bridge. It was expected to cost $1420000 and it was done for only $1300000. The second activity was the pouring of the concrete. This was expected to cost $10500000 but was actually done for $9000000. The third and final activity is the actual construction of the bridge superstructure. This was expected to cost a total of $8500000. To date they have spent $5000000 on the superstructure. Calculate the cost and schedule variance and the schedule and cost performance indexes for the project.
