Any construction project schedule is a sequence of a number of activities having a fixed duration. If there is a delay in any activity which lies on the critical path of the project schedule then it will delay the project completion date & will lead to time overrun. Time overrun is very important for project success. It may be due to the contractor’s fault, the client’s fault, interface contractor’s fault or due to force majeure. It’s necessary to analyze the cause of delay & if the delay is not due to the contractor’s fault than the contractor is entitled to the EOT. EOT claim requires the involvement of different departments. This PDF discusses the protocols followed in claiming EOT & suggests about the amendments to be taken to eliminate disputes in the process of claiming EOT.
Extension Of Time In Construction (Time Impact Analysis Method)
As the project is evaluated through cost & time. The time taken to complete the project & cost incurred in project completion, the success of the project is estimated by these two main factors.
- Preparation of work schedule including an outline narrative statement within 15 days from the notice to proceed.
- First,3 months rolling schedule to be submitted within 30 days of the notice to proceed.
- Submission of detailed version within employer consent to the proposed initial work schedule.
- Submission of the baseline schedule after consulting with other interfacing contractors if any, against which actual progress of the contract shall be reckoned.
- Review by owner & correction of the program if any.
- Proper updating of the program.
- If the updated schedule indicates an actual or potential delay in the contract completion date or key dates, identify a cause of delays.
- Split between contractor fault & delay due to the owner, interface contractor & force majeure delays.
- Prepare evidence for the delay.
- Extension Of Time claim on delays not due to the contractor’s fault after deduction of concurrent delays.
- Updating the baseline schedule on granting of an extension of time by the competent authority.
How to prepare a claim for an extension of time
When it becomes reasonably apparent that there is, or that there is likely to be, a delay that could merit an EOT (extension of time), A formal letter is addressed to the contract administrator requesting the extension of time, presenting the reasons, and referencing the contract clause that allows the request.
Here below a brief about Preparing an EOT Claim Preparation:
All events and issues which either cause, appear to cause, or have the potential to cause delay should be recorded by the contractor including:
- When the event occurred.
- Reason for the event occurred.
- The activities that it affected
- The resources that it required
- List of affected activities from the approved schedule.
- Sketches, photographs, plans.
- Communications between the construction team relating to possible delays.
All extension of time claims should address the following:-
– EOT Claim should identify delay events
– EOT Claim should contain Liability for each event
– Extension of time claim should contain Cause & Effect for each event
– Concurrency (If found)
– Consideration needs to be given to who owns the float in the schedule and the effect this has on the revised Completion Date
– Delay analysis
There are four groups categorizing most of the recognized extension of time (EOT) assessment techniques:
C- Prospective analysis.
D- Retrospective analysis.
