Small Construction Project Earned Value Case Study CPMGT/305 ✓ Solved

You are preparing a status report for your project sponsor and stakeholders and it's important to share the project progress using the Earned Value technique. You are preparing your status report for the period ending October 28th. Your project started February 27th. Assume that the project is executed 5 days per week and 8 hours per day with some additional hours that amount to 8 hours every Saturday and Sunday.

Question 1: Forecast the duration of the activities that are currently in progress assuming their current rate of progress will continue till the end of the project. Determine activities in progress (ID 30 and ID50) - Less than 100% complete. Calculate actual duration from activity start date to status date for each activity in progress. The remaining duration calculation must be computed using the % of work completed to date.

Question 2: Calculate the Planned Value (BCWS) based on the original budget, the original duration, and the number of weeks between the planned early start date and the status date (October 28th for the activities that are in progress).

Question 3: Calculate the BCWP (Earned Value). This is based on the original budget and the actual work completed for the activities that are in progress.

Question 4: Calculate the Schedule Performance Index (SPI) and the Cost Performance Index (CPI) based on BCWS and BCWP. Based on these calculations, determine if the project is ahead or behind schedule and if the cost is under or over budget.

Paper For Above Instructions

The earned value management (EVM) technique is critical in monitoring and evaluating the performance of a project. This method enables project managers to assess their project’s status and make informed decisions as they proceed with the project execution. In this case study, we will follow the steps outlined in the instructions to calculate the necessary metrics related to the project’s status report for the period ending October 28th.

Question 1: Forecasting Duration of In-Progress Activities

The project has two activities currently in progress: Activity 30 (Super Substructure) and Activity 50 (Interior). According to the data provided:

  • Activity 30: Super Substructure has an actual duration of 75% complete.

  • Activity 50: Interior has an actual duration of 50% complete.

To forecast the duration for these activities, we first calculate the number of weeks from the start date to the status date, October 28th, for both activities:

  • Activity 30 (Super Substructure): Started on July 20, 2022.

  • Duration from Start to Status Date: 14 weeks.

  • % of work completed: 75%.

  • New Duration at 100% = 100 * (14 weeks) / 75 = 18.67 weeks.

  • Remaining Duration = 18.67 - 14 = 4.67 weeks.

For Activity 50 (Interior):

  • Started on August 31, 2022.

  • Duration from Start to Status Date: 8 weeks.

  • % of work completed: 50%.

  • New Duration at 100% = 100 * (8 weeks) / 50 = 16 weeks.

  • Remaining Duration = 16 - 8 = 8 weeks.

Question 2: Calculating Planned Value (BCWS)

For BCWS, we will use the original budget and original durations:

  • Activity 30: Original Budget = $2,000,000, Original Duration = 18 weeks.

  • Weeks to Status Date = 14 weeks. BCWS for Activity 30 = (14 / 18) * $2,000,000 = $1,555,555.56.

For Activity 50:

  • Original Budget = $1,800,000, Original Duration = 14 weeks.

  • Weeks to Status Date = 8 weeks. BCWS for Activity 50 = (8 / 14) * $1,800,000 = $1,028,571.43.

Question 3: Calculating Earned Value (BCWP)

The earned value (BCWP) for each activity based on the original budget and their actual percent complete:

  • Activity 30: BCWP = 75% * $2,000,000 = $1,500,000.

  • Activity 50: BCWP = 50% * $1,800,000 = $900,000.

Question 4: Calculating Performance Indices

To determine the project's efficiency, we calculate the Schedule Performance Index (SPI) and the Cost Performance Index (CPI):

  • For Activity 30:

    • SPI = BCWP / BCWS = $1,500,000 / $1,555,555.56 = 0.964 (Behind Schedule).

    • CPI = BCWP / ACWP = $1,500,000 / $1,450,000 = 1.034 (Under Budget).

  • For Activity 50:

    • SPI = BCWP / BCWS = $900,000 / $1,028,571.43 = 0.875 (Behind Schedule).

    • CPI = BCWP / ACWP = $900,000 / $1,000,000 = 0.9 (Over Budget).

Conclusion

In summary, utilizing the earned value management provides a clear picture of the project’s performance. While the activities are falling behind schedule, especially Activity 50, they are under budget for Activity 30, indicating that there are areas needing improvement and adjustments to ensure project completion within the desired time frame and budget.
