Construction Claims Management & EOT Delay Analysis

Agenda • Introduction.

• Why is TIA preferred technique ?

• Window Analysis Technique

• Window Analysis Technique Steps

• Smart Windows Time Periods




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 WWW.PLANNINGENGINEER.NET


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.

- Analysis steps




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.




Window Technique – Analysis Steps

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.WWW.PLANNINGENGINEER.NET
