Delay analysis technique and Metrology

The technique for delay analysis utilized in this claim is “Time Impacted Analysis” and “Window analysis” in order to measure the impact of all delay events accurately. 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.

 

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 of the project life cycle is divided into a series of consecutive time Windows.

 

 

For Each window

1. 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

 

1. 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 within 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.
