Construction Claims Management & EOT Delay Analysis
Introduction
Time Impact Analysis Technique is Actual Based Approach
Which depends on the actual consequence and dates
happened in the site during the execution not only the
planning schedule.
TIA is widely recognized by the construction industry as
the most accepted method to quantify schedule delay.
In this method the analyst develops and adds a model of
the change to an approved schedule to quantify the delay
to project completion

TIA is preferred delay analysis technique
TIA is preferred delay analysis technique for the following reasons
it allows assessment of the actual state of progress at the time the
delay event occurred.
the responsibility for delay prior to the impact of the delaying event
is not material to the calculation of the effect of the delaying event
itself.
It determines whether the delay event impacted the critical path.
The exact impact of the delay event can be calculated.

Window Analysis Technique
Window analysis is a time impact technique which focus on the
impact of delays in specific periods of time , identifying gains or
losses ( delays and recovery ) to the actual critical and sub-critical
paths as they occur with each period of time.
The project life cycle is divided into a series of consecutive time
“Windows”.

Window Analysis Technique – Cont’
For Each window
-
Each window is analyzed
to identify the activities that were
impacted , delay or recovery and the results are investigated to
identify the events that caused the deviation in progress.

Construction Claims Management & EOT Delay Analysis
Window Technique – Analysis Steps
Step 1 : Incorporate delay events that have been occurred in the period
Step 2 : Establish the impact on time for Completion.

Step 3 : Update the impacted programme with progress with in the
window period.
Step 4 : Establish the impact on the Time for Completion.
D1 : Impact delay period due to “Employer Delay Events”
D2 : Impact delay period due to “Contactor Delays ” from the
update.
