Website Upgrade Incoming - we're working on a new look (and speed!) standby while we finalise the project

Tips on using this forum..

(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.

Our contract manager ask me to prepare Impact time delay based on "updated programme of that time (week)", so we can plug those late information and see what is the impact of that indivisual activity on clause-14 i.e. in the updated cluase 14 programme.

Any one have done this before, some one wanna share his experience in the forum

I think you are asking two questions here, i’ll assume that i understood you correct and will go further,

First:

The client/consultant delayed the approval of submittal, hence delayed the procurment and accordingly the activities. The answer is: please read my post above.

Secondly:

You found out that the planned duration as lead time for material delivery is not approperiate,
The answer is: Sorry, you have to replan and meet your dedlines.

Fianlly:
for example the client decisions delayed you by 10 days, and the suppliers need 120 days for delivery rather than the 90 days requiered.

Then total delays (assuming the delays are in the same itemm hence summing both of the delays) 10 form the client side plus 30 by your supplier, which you are responsibile of, total 40 days.

You will have to change the sequence of the works, increse manpower in critical path acitivites, or both in order to catch-up 30 days which fall in your end.

Furthermore, if the suppliers firstly had a contract and comitment with you with a sepcific lead time, they will have to compensate you if you suffers from a delays due to their failure to meet the schedule. for example the cost of extra man[power can be in theri account, but be sure to have a clear contract condition regarding that issue first.

On the other hand, if you can prove that the client delays is a sole and direct reason for delaying the delivery more than 90 days as you assumed, all of the delays will fall in the client end, for example, the client approval was extinsevly delayed that the materials approved is discontinued, and new model took place in the factory, or such like.

Ya!

One thing more, its not a variation, it is a ID package, at the project initial stage, we assumed all information having procurement time as of 90 days. Later when we got information in detail, can we change the procurement duration, now supplier needs more days?

Shahab

Thanks walied!

I want to insert an activity of release of information and wanna keep procurement duration as it was in clause fourteen, the programme updated as on 31/01/06 has same negative float as by inserting new information, i.e. start date of procurement is same as in clause 14 updated programme. So it has no impact on end date. Can i suggest new procurement duration to lengthen the critical path, how i can prove new procurement duration.

Regards,

Shahab

Briefly,

1) update the prorgamme untill the date in whcih the new activity shall be commenced, reschedule, correct all out-of-sequence activities shown in the scheduling report.

2) add the new activity to the proer location in the programme, and link it.

3) reschedule, (you might get nigative float, do not panic)

4) make sure that all the up-coming activities has proper links, for example, make sure that the cricail path is really critical not due to bad linking. (some time, depsite it is not professional planning, but some contractors tend to make links just to get dates, for example, linking installing elevators with starting of ceramic tilling in bath rooms!!)

5) if the negative float still there, that is the time extenstion you as contractor might be entitled to.

6) if the activity once lined as in step 3, did not generate nigative float, so it is not in the critical path, but you still need to make sure that the upcoming activities are linked properly. who know, may be after correcting links it become critical.

7) this analysis also can prove your acceleration cost, document any cost you encountered to bring back the project in-line.

As your post only addressed a new activity, I am assuming that it is due to variation order from the client.

Also, the above steps did not consider the analysis of con-current delays, in whcih the Contractort might be delayed in another area, that is another story.

In addition to all that, you have to read the contract very well in this area, check what is contractually requiered by you to prove your entitlements.

Hope thats help
