THE SEMINAR

will be presented in logical and systematic flow to cover theinvestments in building projects from selecting the appropriatebusiness models, feasibility, design, technical audits, permits,construction, handing over and finally operations.

The sustainability implementation during each stage shall also becovered in the sustainability section. At the end there will bemovies and photos to show the story of selected projects duringthe construction stage. This has been prepared inline with theagenda and letter of the invitation.

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

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)

Project Phases ( After Bid)

“Required drawings-specifications to proceedwith procurement and construction”

WEIGHTING METHODOLOGY

Applications

Engineering:

Example of coordinated drawings needs to besuperimposed to eliminate conflicts between disciplinesand allow them to be executable.


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


•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.
