REVIEW OF PROJECT REPORTING
CONSTRUCTION REPORTING
•Construction is a risky business for all the team players.•Reporting is the “GPS” for the unknown paths of the construction projects. (humaninterpretation, room for assumptions)
Decision makers: Owners, investors, insurances, designers, technical, costengineers, managers
Project Navigation Pattern

REVIEW OF PROJECT REPORTING 33
PROJECT LIFE CYCLE
Tender Triggers Reporting
Interdependent three mainphases for reporting should beequally observed
• Engineering (approx. 10 % of theproject price)
• Procurement (approx. 40 % of theproject price)
• Construction / Installation /Commissioning (approx. 50 % ofthe project price)

WEIGHTING METHODOLOGY
Applications
Engineering:
Example of coordinated drawings needs to besuperimposed to eliminate conflicts between disciplinesand allow them to be executable.
REVIEW OF PROJECT REPORTING 38
Status Percentage
Not started 0%
Initiated 15%
Prepared for construction 40%
Checked/approved 65%
Released for execution 100%
Applications
Procurements:
Status Percentage
Not started 0%
Request for Quotation 10%
Purchase order issue 25%
Sent by Suppliers 95%
On site arrival 100%
This method would be very effective for long leaditems where delivery is critical.

CONCLUSION
REVIEW OF PROJECT REPORTING
•Quality of the works done is not addressed inmany of the reporting methods.
•Most of the reporting method providesmonetary information only.
•It is important to have a comprehensiveapproach when reporting, keeping all the phasesinto consideration.
•Weighting analysis technique can be a goodsource for problem diagnosis phased duringconstruction and for tracking data for claims.
•Proper reporting leads to precise control andeconomics results.
