Introduction

This is an exercise to calculate progress based on Client requirements for a typical EPC Project.

Data used on this sample are referential and were created just for better understanding of this Progress Calculation exercise.

This is open to anybody for comment or improvements.

Client Requirements

An EPC Project is required to be scheduled and follow up each of its phase and based on these following requirements:

1. Project must start on Nov 1rst 2010 and must be done in 200 working days

2. Working Time will be 8h/d; 40 hours a week (Standard Calendar to make simple the exercise)

3. Phases must be weighted on cost except Engineering phase which will be weighted on man-hours to be expended (Effort)

4. Resources and Cost have to be established for all phases5. The Weights of each Project phase must be:

a. Engineering Design = 10%

b. Procurement = 20%

c. Construction = 70%

6. Schedule must show Progress Earned Values against Planned Progress Values

7. Schedule must show also a Graphical Baseline to evaluate future Project Performance and targets achievements

8. Progress figures to be reported are Physical and Earned Values9. For Forecasting: Task endings dates will be given by using remaining durations

Note: The main purpose of this exercise is to show Progress Calculations. So, no actual values on resources and cost expenditure are

being given

3. Weight Assignmenta) Create three new user defined fields (Enterprise\User Defined Fields) given the following titles:

% Progress Earn Value

Planned % Complete

Weight

Figure 05Note: Once are created show

them as on Figure 04 - Last 3

columns

b) Using Global Change (Tool\Global Change) create the following changes for each phase:

ENGINEERING PHASENote: Parameter/value

number which divides BLU comes

from Figure 04 (BLU Column)

Weight for Engineering = 10%

c) Apply Global Changes one by one and then we will get the committed changes or weights:

Engineering = 10% Procurement = 20% Construction = 70%

4. Update the Schedule for: Figure 10 Cut Off date = February 1rst 2011 (Data Date)

Give % Physical Progress

And Remaining Durations

FINAL COMMENTS:

1. If all the phases were weighted on cost only two global changes should be made

2. Usually weights are being frozen by the client before project stars therefore the Global Changes which calculate activity

weights are being applied or done only one time

3. If there is any changes that affect Budgeted Labor Units (BLU) or Cost, weights have to be re calculated using again the

Global Changes made for that purpose ( Advice: Always check the GC parameters/values field and update these values

with those originated by the new changes to make sure you are weighting activities properly)

4. Every time the schedule is updated base on physical progress and remaining durations it is required to re calculate

progress values by applying last Global change made for it (GC No. 4)

5. Weights can be calculate out of Primavera for example in Ms Excel and can be added to the Weight Column manually

or using Primavera to import them from Excel Spreadsheet

6. Feel free to make any comments or suggestions
