Delay And Time Impact Analysis
Claim Management is a method of entitlement analysis for incurred project impacts. This method considers multiple evaluations and considerations such as Time Impacts.
Time Impact Analysis (TIA) is a schedule delay analysis procedure developed to facilitate the award of contract time extensions due to delays that are not the responsibility of the General Contractor. A fragnet is developed which is a fragmentary network for the issue (i.e. the change). It’s like a little mini-schedule for the change. Then that fragmentary network is dropped into contemporaneous schedule, and then look to see how it affects that schedule.
TIA is a “Forward Looking” prospective analysis which models and determines the impact of a delay to project completion on a project schedule baseline or update.
There is a difference between What-If analysis and TIA. A What-If-Analysis is an exercise to look at potential options before an impact occurs.
Why to develop a TIA:
- Unforeseen Conditions
- Owner Equipment Delays
- Limited/Restricted Access
- Change in Design
- Change in Contract Requirements
- Environmental Impacts
- Excessive Adverse Weather
- Defective Contract Documents
It requires a CPM schedule that enables comparison of the BEFORE and AFTER pictures to find the impact of the delay events that are beyond your control.
