Question

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 70% complete. The planners were expecting to be only57% through the third activity at this time. The first activity involves prepping the site for the bridge. It was expected that this would cost $1,427,000 and it was done for only $1,307,000. The second activity was the pouring of concrete for the bridge. This was expected to cost $10,507,000 but was actually done for $9,007,000. The third and final activity is the actual construction of the bridge superstructure. This was expected to cost a total of $8,507,000. To date, they have spent $5,007,000 on the superstructure. Calculate the schedule variance, schedule performance index, and cost performance index for the project to dat

Answer 1

Schedule variance = $1,105,910

Schedule performance index = 1.066

Cost performance index = 1.168

Step-by-step explanation:

Note: The requirement of the question is not complete. The complete requirement is therefore provided before answering the question.

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.)

The explanation of the answers is now provided as follows:

Budgeted cost of work schedule = Expected cost of first activity + Expected cost of second activity + (Expected cost third activity * Expected percentage of completion) = $1,427,000 + $10,507,000 + ($8,507,000 * 57%) = $16,782,990

Budgeted cost of work performed = Expected cost of first activity + Expected cost of second activity + (Expected cost third activity * Actual percentage completed) = $1,427,000 + $10,507,000 + ($8,507,000 * 70%) = $17,888,900

Actual cost to date = Actual cost of first activity + Actual cost of second activity + Actual amount spent on third activity to date = $1,307,000 + $9,007,000 + $5,007,000 = $15,321,000

Therefore, we have:

Schedule variance = Budgeted cost of work performed - Budgeted cost of work schedule = $17,888,900 - $16,782,990 = $1,105,910

Schedule performance index = Budgeted cost of work performed / Budgeted cost of work schedule = $17,888,900 / $16,782,990 = 1.066

Cost performance index = Budgeted cost of work performed / Actual cost to date = 1.168
