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 75% complete. The planners were only expecting to be 55% through the third activity at this time. The first activity involves prepping the site for the bridge. It was expected that this would cost $1,435,000 and it was done for only $1,315,000. The second activity was the pouring of concrete for the bridge. This was expected to cost $10,515,000 but was actually done for $9,015,000. The third and final activity is the actual construction of the bridge superstructure. This was expected to cost a total of $8,515,000. To date they have spent $5,015,000 on the superstructure.
