Introduction
Project Monitoring & Control Ideal Control System Main Elements: Cost, Time, Quality and Safety
Techniques: Leading parameter Activity based ratios Variances Earned Value Performance Measurement (EVPM)

Ideal Control System
Example: Construction of a bridge Budget: $10’000’000 Project Duration: 1 year After 6 months, we have received an invoice
of $5’000’000. The question is how much job really done?
More accurate answer, ideal Control System

EVPM Background
Industrial base – at the turn of the 20th century
US - Department of Defence Idea took root in 1960’s C/SCSC (35 criterions) in 1967 Emerged as a PM tool in the early 1990’s

2 – Budget Cost Allocation
Locate the 4th or 5th level of WBS. Get the direct cost info. Allocate costs over each Work Package. Allocate the linear relationship or a more
accurate non-linear expenditure against time.

5 – EVPM calculation
EV(BCWP) = % Comp x PV(BCWS)
Schedule Variance (SV) = EV – PV Cost Variance (CV) = EV – AC SPI = EV / PV CPI = EV / AC PCP = PV / Total Budget PCA = EV / Total Budget EAC = AC + ETC

Conclusion
EVPM is a good tool for improving the analysis of progress and performance on a construction project.
Although level 4th WP’s give accurate results, site engineers feel more confident at 5th level.
General overheads and profits should be eliminated from the analysis so that actual expenditure can be directly compared with budgeted expenditure.
Within this closed network, activities are updated with time data and WP’s updated with cost info.
The test data needs to be expanded with data from a wider range of road projects to provide more practical usages and procedures of EVPM system.
Getting the accurate cost figures from financial dept and the real time and performance data from site engineers, makes the EVPM system a reliable performance measurement tool.
