Construction Law/Impacted As-planned Analysis


Dear Sir
I have met a real time scenario where an Impacted As-planned delay analysis is being performed retrospectively in order to identify the impact of some alleged delays. I know it's not a favourable method but in the absence of any updates, the baseline schedule is all we got!

We have a curious situation at hand because some activities, originally in the baseline schedule, were cancelled later during the project execution. Do you advise that i delete it from the baseline schedule (what should i do with the links to both predecessors and successors?) or should i just change the duration of this cancelled activity to Zero while keeping it and its links?
I hope i made myself clear.
Thanks for your time

Dear Abed,

I am not an expert in TIA.  I would not delete the activities, but reduce their durations to zero, which would have the minimum effect on the analysis.  However, I would consider the timing of the instruction to omit the work and the possible disruption effect.

Value . . .
It's unwise to pay too much, but it's unwise to pay too little. When you pay too much you lose a little money, that is all. When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing you bought it to do.
The common law of business balance prohibits paying a little and getting a lot. It can't be done. If you deal with the lowest bidder, it's well to add something for the risk you run.
And if you do that, you will have enough to pay for something better.
