The above Sample Construction Delay Report
is based on the following entries:
Project Title: Sample Project
Start Date:January 01,2014
Finish Date:January 01,2015
Cut-Off Day:October 01, 2014
Cumulative value of completed works:65000
Value of Completed works during the month:10000
The following findings are concluded from the Delay analysis:
Estimated Current Construction Delay: 53 days
Estimated Probable Construction Delay upon completion of the Construction Works: 85 days
Estimated Earliest Completion Date: February 23, 2015
Estimated Latest Completion Date: March 31, 2015
Most Probable Completion Date of the Construction Project: March 27, 2015
Slow performance accounts for 86% of the Project delay
Disruption to the works accounts for 14%
Project Delay Analysis
The Violet, and the Red S-curves represent boundaries for the analysis.
The Violet curve assumes a shifting to the right with the amount of encountered delay at the Cut-off day. The Red Curve represents the case where performance is continuous but slow. Each case would result an updated Finish Day.
The two curves are calculated at the Cut-Off day and one month earlier.
From the two curves at the earlier date, we calculate what would be the progress at the end of the month, then we compare the current actual progress with the two figures obtained above to determine how close it is proportionally to both boundary figures.
The proportions are then applied to the curves drawn at the end of the month to find the most probable updated Finishing Day
Same proportions are considered as shares of responsibility.
The Report is based on the S-curve analysis
. While this analysis is accurate enough to produce reliable predictions, it must be noted that in case events of disruption are evident and properly documented, the responsibility shares would have to be revised.
