First Point - was there enough detail behind the provisional sum to establish the 8 months duration? In other words could an experienced planner create a detailed programme for phase 2 on the information in the tender.
If NO - then the 8 month programme is also provisional and a reasonable period should be allowed for waht is being done.
If YES - then is the original scope of the provisional sum different to what is now being built - a new programme is required.
In either case a new programme must be prepared to demonstrate the valididty of the original 8 months.
Second Point - You are responsible for collating the Event Log so you need to research all your claim heads and establish the Impact Date.
This is the latest date that you could start work on the delayed section of the work - be aware that it is not necessarily the date on a piece of paper because instructions are often issued retrospectively ANDyou have to allow for all lead in items such as Design - Approval - Procurement etc.
The Event Log is the record of Event Cause - the Analysis is demonstration of effect.
Third Point - A Time Impact Analysis (UK SCL Definition) is better used while work is in progress. Succes of the method in a forensic situation depends entirely on the quality of your as built records. If your As Built data is poor then you cannot do a Forensic TIA.
I would suggest a much simpler approach.
1. Check the true duration of Phase 2
2. Set the start date of Phase 2 to 1-Jan-11 and constrain it.
3. Reschedule to get your EoT entitlement date.
4. Check with your actual or projected completion date.
Your EoT entilement will be either the Impacted date or As Built date - whichever is the earlier.
It is unlikely that any sub events on your log will cause any further delay unless they impacted on phase 2 and anyone trying a windows analysis is wasting their time.
