(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?
(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.
Hi Guys,
May I request an assesment on this;
Given:
Phase 1 (unit rate)
Phase 2 (provisional sum)
Both phases are in one contract with the duration of 20 months commencing 1 Jan 2009 - 1Aug 2010.
Now, there is approved program which the Phase 1 will start on 1 Jan 2009 and finish on 1 August 2010 and Phase 2 will start on 1 Jan 2010 and will finish on 1 August 2010. The Engineer gives notice to proceed for Phase 2 on 1 Jan 2011. The question is which duration will be implemented? 20 months or 8 months for phase 2? For me it is 8 months since the program is approved by the Engineer. The Approved Baseline will be the Contract Program. As PE now I need to do Time Impact Analysis. (please tell me the difference of TIA from Forensic). Engineers are using Window Analysis which I dont know and they are not using the Calendar. To do the TIA first I need to have the Event Log (which will include the dates of Notification of all parties, Proposed Action Date, Events and etc.) Engineers are refusing to give me this datas because according to them its not their work. Second, my point is why the Engineers are not associating the events in the Condition of the Contract. They are saying that the Client are delayed for giving notice to proceed the work for Phase 2. For me, its a PS and since they know that they will be delay, Why the Contractor did not send any notification as per the condition of the contract?Now, what will be the basis of the Engineers for the delays encountered? What will be the best basis for the delay computation for this?

Hi Mervilyne.
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.
