Inference:
Scheduled Performance Index: The schedule performance index of WBS 1, 2, 3 and 4 is 100%. Therefore, it can be inferred that the cost of these tasks was completed as budgeted. The schedule performance index of WBS 5.2 is 25%. It means, the work completed is less than the budgeted plan. Hence, WBS 5.2 is lacking behind the schedule.
Cost Performance Index: The cost performance index of WBS 1 is 100%. It means the actual cost and budgeted cost are equal. The CPI of WBS 2 (including 2.1 and 2.2) is 83.3%. It means the planned value is 83.33% of the actual cost. The CPI of WBS 3 is 111.111%. This means the WBS 3’s actual cost was less than the projected cost. There was cost saving in this WBS.
The CPI of WBS 4 is 93.33% and WBS 5 is 64.70%. Again, in these two tasks the actual cost has shot up. To further break it down, WBS 5.2 has CPI of 20%. This is a main area where the company has incurred too much of cost when compared to its budgeted cost.
Estimate at Completion is calculated based on the assumption the project’s experience until now will be continued. Hence, the formula used would be as below:
EAC = BAC / CPI
BAC is the total planned value of the project and this stands at $1520 million.
The CPI is Earned value / Actual cost and this stands at 78.48%.
Therefore, the estimate at completion = 1520/78.48% = 1,936.80
The overbudget amount = EAC – BAC = $1,936.80 – $1,520 = $416.80million
The following can be the reasons for the cost overruns:
As total cost may increase by $416million, there is a need for re-baselining. The baseline being the planned value, this has to be restated with the proper approval from the required team.
The formula to calculate the To-Complete Performance Index (TCPI) when BAC is invalid is stated below:
TCPI = (BAC – EV) / (EAC – AC)
TCPI = (1,520 – 930) / (1,936.80 – 1185)
TCPI = 590 / 751.8
TCPI = 0.7848
Here is the summary of Cost:
Total planned value = $1520 Million
Total Earned Value as on June 30, 2018 = $930 Million
Total Actual Cost as on June 30, 2018 = $1185 Million
Estimate at Completion = $1,936.80 Million
Over Budget Cost = $416.80million
Forecast Completion Date = Total Duration of the project / SPI
Total duration of the project = (June 30, 2020 – July 1, 2015) / 61.18%
Total duration of the project = 1826/61.18%
Forecast completion date = 2985
Forecast completion date = June 30, 2020 + 1158 days
Forecast completion date = September 1, 2023.
Re-baselining the project is necessary in this case as the project that was scheduled to be completed in mid-2020 is now extended till mid on 2023. This will increase the costs and the entire project would be off the track if the rebaselining is not done. Hence, we would want the approval from the required team for the rebase lining the project.

Project name: Sydney CBD and South East Light Rail project
Date: June 30, 2018
Project ownership: ALTRAC
Prepared by: Project Manager
Distribution list: List of those receiving the report, their positions and role in the project.
This exception report is related to the project Sydney CBD and South East Light Rail Project. The project was supposedly completed on June 30, 2020. But, because of various reasons, the team is not able to complete the project on the scheduled date. The forecasted completion date stands at September 21, 2023. This means, the project may take 1,158 more days than the estimated due date to get completed, this is little more than 3 years of project extension.
The tolerance provided by the team is +/- 12 weeks, that is approximately 84 days. Hence, it can be concluded that the project completion date deviation is lot more than the tolerant value.
This gives us the provision to compile the over the schedule exception report to the concerned authority. If this known deviation is not reported at the earliest, the Government, the contractor company and the general public will be affected with this project. We seek for the guidance on this issue from the higher authority as well as we give the suggestions for team to manage this behind-schedule project.
We henceforth, present this exception report to the concerned person for a better understanding about the reasons for the behind schedule project, recommendations and the lessons that is learnt from the same.
3.1 Exception title
|
Behind the Schedule Exception Report of Sydney CBD and South East Light Rail project |
3.2 Cause of the exception |
The major cause of the exception is listed below: · The redundancies were found in George Street that took the team almost 5 extra months to clear. (Hawke, 2016) · Legal action was commenced against by Acciona seeking additional payments. (Anon., 2020) |
3.3 Consequences of the deviation |
It is important to address the deviation. If this is not addressed the following would be the implications: |
3.3.1 The project: - If this deviation and the reasons for the deviation is not addressed for, the major key performance indicators would lack its value. - This is the way to prepare the public and the government for the delay. This can also cause the increase in the labour cost. - The project extension can lead to increase in the cost of material due to the time factor of money. |
|
3.3.2 The corporate, programme management or the customer - The customer/public will face the irritation of the construction for few more months than expected. Hence, it is necessary to keep them informed. - The Government would be answerable for everyone for the project delay and also for the increased cost of the project. Hence, it is important to keep them informed and to seek the advice to overcome the same. |
|
3.4 Options
|
The following options are available to manage this delay of project completion: - Going forward speeding up the work in all possible stages by deploying the labour for 24/7. - Accepting the reality of the delay and getting set for bearing the increased cost. |
3.5 Recommendation
|
The most feasible option would be speeding up the work in all possible stages by deploying the labour for 24/7. Though this would not make the project to be completed as per the pre-decided timeline, it will at least not take three extra years to complete. In this way, the Construction company can retain its name and the blame on the Government for the project delay by the public would be reduced. |
3.6 Lessons
|
1. During such projects, we can come across unforeseen problems like that happened in this case by finding the redundancies. Hence, it is necessary to make sufficient provision for such unforeseen problems while planning for the project. 2. Preparing a comprehensive terms and conditions document would reduce the legal consequences during the project period. |
