Question $1$: $(5$ points$)$

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 that this would cost $$1,420,000$ and it was done for only $$1,300,000.$ The

second activity was the pouring of concrete for the bridge. This was expected to cost $$10,500,000$ but

was actually done for $$9,000,000.$ The third and final activity is the actual construction of the bridge

superstructure. This was expected to cost a total of $$8,500,000.$ To date they have spent $$5,000,000$ on

the superstructure.

Calculate the schedule variance, schedule performance index, and cost index for the project

to date. How is the project going?
