QUESTION 01 - POST-CONTRACT CASH FLOW (30 MARKS)
Once the project was awarded to Hogwarts Construction, the Construction Manager asked you to prepare the cash flow forecasting for the project. The planning engineer has prepared the detailed construction programme, and the Table 01 data was passed on to you. In addition to that, the following details are from the contract document.
Retention Retention is deducted according to the guideline in NZS 3910: 2023
Estimated profit of the project 20%
Defects liability period 3 months
Payment claim vs certified payment Payment claims amount and the certified payments are the same, with no adjustments (GST is not required to be calculated)
Task 01 (5 marks) - Submission: Excel file
Using MS Excel, the above information calculate the following for the project from the 1st month to the final completion of the project. If any assumptions are required, please list them clearly.
a) Cumulative budget
b) Cumulative payment claims
c) Cumulative revenue
d) Cumulative expenditure
e) Cumulative capital
Task 02 (4 marks) - Submission: Excel file
Looking at the calculations, the project team requested an advance payment to reduce the negativity of the cash flow at the beginning of the project. Therefore, using the advance payment information given below, recalculate the task 02 items.
Advance payment 10% of the Contract Sum
Advance Recovery The Advance will be recovered 25% from each monthly payment before deducting the retentions. The advance payment recovery will not start until the overall progress reaches 10%
a) Advance recovery
b) Cumulative payment claims with advance
c) Cumulative revenue with advance
d) Cumulative capital with advance
Task 03 (6 marks) - Submission: Excel file
Looking at the material calculations for each month, the construction manager requested you to consider the material on-site and off-site to reduce the negativity on the cash flow even further. The following table shows the material cost for each month. Assume that these materials will be purchased in the previous month. You can include the material cost as an advance for the previous month's payment claim.
Month Material cost for each month (NOT cumulative)
1 63,344.32
2 274,492.43
3 443,410.27
4 570,097.84
5 654,555.14
6 696,782,16
7 696,778.92
8 654,545.41
9 570,081.62
10 443,387.57
11 274,463,24
12 112,606.54
Using the above material costs, calculate the following:
a) Cumulative payment claims with advance + material advances
b) Cumulative revenue with advance + material advances
c) Cumulative capital with advance + material advances
Task 04 (8 marks) - Submission: Excel file
Using the calculations in Task 01 and Task 02, create graphs to show the following:
a) Cumulative budget curve
b) Cumulative revenue curve
c) Cumulative revenue with the advance curve
d) Cumulative revenue with the advance + material advances curve
e) Cumulative expenditure curve
f) Cumulative capital curve (sawtooth diagram)
g) Cumulative capital with the advance curve (sawtooth diagram)
h) Cumulative capital with the advance + material advances curve (sawtooth diagram)
Task 05 (7 marks) - Submission: Word file
Using your answers for Tasks 01, 02, 03 and 04, explain the expected behaviour of the project cash flow. (100 - 200 words)
QUESTION 02 - POST-CONTRACT COST CONTROL (20 MARKS)
The project reached the end of the 5th month, and 30% of the project is completed.
Task 01 (5 marks) - Submission: Excel file
Using the information from question 01 above, calculate the following.
a) Cumulative Planned value (PV) at the end of the 5th month
b) Cumulative Actual Cost (AC) at the end of the 5th month
c) Cumulative Earned Value (EV) at the end of the 5th month
d) Cost Variance (CV) and Schedule Variance (SV) at the end of the 5th month
e) Cost Performance Index (CPI) and Schedule Performance Index (SPI) at the end of the 5th month
Task 02 (3 marks) - Submission: Excel file
Draft the information into an S-curve chart to show the status of the project. Label the PV, AC, EV, CV, SV and BAC on the curve.
Task 03 (2 marks) - Submission: Excel file
What is the expected completion date if Hogwarts Construction wants to maintain the same SPI and CPI for the remaining part of the project? (List any assumptions made)
Task 04 (2 marks) - Submission: Excel file
What is the expected estimate at completion (EAC) at the end of the project if Hogwarts Construction wants to maintain the same SPI and CPI for the remaining part of the project?
Task 05 (3 marks) - Submission: Excel file
What efficiency/ performance rate is to be maintained to finish the project (To Complete Performance Index)? You have to calculate all the possible options.
Task 06 (5 marks) - Submission: Word file
Using your answers for tasks 1 to 5, provide a cost update explaining the project’s current status and forecasting for the rest of the project. Evaluate all the TCPIs from task 5 and decide which is the most feasible option with an explanation.
QUESTION 03 - CLAIMS PREPARATION (VARIATIONS) (20 MARKS)
The attached is the layout plan of the proposed house for Mr & Mrs Potter. The principal has suggested a few changes to the current design based on their requirements, as mentioned below. Contract Administrator Hermione issued a site instruction (SI no. 10) for variations as below. SI-10 is attached in Annexure A.
Task 01 (5 marks) - Submission: Excel file
• Take off the quantities for the variation items. You may use either CostX or MS.
Excel. However, you need to show the quantities and how you measured them clearly.
Task 02 (10 marks) - Submission: Excel file
