Problem 5-6 (Algo) 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 a very low. A major milestone has been reached where the first two activities have been totally completed and the third activity is 68% complete. The planners were expecting to be only55% through the third activity at this time. The first activity involves prepping the site for the bridge. It was expected that this would cost $1.418,500 and it was done for only $1.298,500. The second activity was the pouring of concrete for the bridge. This was expected to cost $10.498,500 but was actually done for $8.998,500. The third and final activity is the actual construction of the bridge superstructure. This was expected to cost a total of $8,498,500. To date, they have spent $4,998,500 on the superstructure. Calculate the schedule variance, schedule performance Index, and cost performance Index for the project to date (Round your "performance index" values to 3 decimal places.)
