Dear gentlemen,

I am in the midst of cracking my head because of the schedule impact i need to prepare in order for my company to take legal action towards our sub con.  Going on, I am compiling the contract between

1. Main Con & subcon contract

2. Daily manpower & manhours 

3. Approved planning package procedure for Client & Main Con (to develop Additive Modeling).

4. Official weather report from government deparment.

5. Site Statistic Record which shows Non Productive Time due to raining, plant permit issues or operational issue.

6. Subcon's Timesheet.

 

On top of that, of course i need to know what happened, what is the cause & who is responsible. In addition, the funny thing is that when i cracked my head to think about it. How do i actually can prove that the downtime is factual while there is not daily report from piping supervisor? Can anyone advice me?

Dear Mike,

 

1. Thank you very much for your prompt response and i appreciate it. Well, as the matter of fact, the schdule model shall base on the events that occured during the phase of construction and etc. This i have no problem to do with my available data.

2." We have to create order from chaos." This i totally agree to put it in one spread sheet. Fine.

3.  From line number 6 to 11 (paragraph) I don't really understand. I hope you don't mind to advice me further.

Going forward, I have already the daily manhours in hand so what i will do is from the approved schedule, i am identifying Act ID & Synchronized it with the affected daily manhours. Next, slot in the columns "what happened, what is the cause & who is responsible. This will be done in Microsoft Excel format as a summary. 

The issue that i have now, I do not have the supporting document to support my paper (the facts) example daily report signed off by client. I know very well, if i provide this to my management they will ask me, "how do you know that there is downtime during that day, how do you prove it?"

Thank you & regards.

Hi Jeffery

Welcome to the Delay Analysis society of crack heads.

What you are experiencing is normal and we have to create order from chaos.

The way that I proceed is to set all available data into one spreadsheet with a field for the affected baseline Act ID.

Weather data should be set into the calendar together with other non productive time that is project global.

Any non productive time that is trade specific needs its own calendar.

None of this will work unless your baseline is responsive.

If you have any of the following then rectify it or forget it:

Constraints

FF or SS links

Lead lags except for curing or drying out periods

Open end logic

Best regards

Mike T.
