Hello Paul,

Always keep the Contracts with you. There you can see the Scheduling Specification/ Scheduling requiments..a well crafted scheduling specs includes the provision for revision of the master programme (approved baseline programme) - a carefully crafted scheduling specification should,if carefully followed make identification of actual delay issues, and the events they relate to, much simpler..soon you will not just exposed to logic changing but claims as well.

I believe you are a subcontractor (MEP) - kindly correct me if not. You have to coordinate it to your main contractor (I agree with our colleague's comments above). Usually, it is written in the provision not to change esp the logic (links). But in the construction world w/c is subject to uncertainties (risks) it is logical & realistic to change the baseline if is not applicable - the baseline purpose was a map to put us on the right track. A guide, we should always put that in mind. If its purpose is not meet, why use it for mapping it will be misleading (my opinion)- update is just a copy of ur baseline, with your figures (activity % complete, actual dates, etc). But you need to coordinate it first to the stakeholders (in your case, your immediate superior, the main contractor, the consultant & the consultant to the Owner). I am in the Consultant side, I usually do a claim digger. I do compare, once I've seen that the contractor have changed the logic, I will inform them, why such action is required?. 

A good planner as they say (the planning veterans) usually knows the legal issues in related to planning. You will definitely use the baseline & the as built schedule (updated w/c you are planning to change the logic ) for claims soon. Better to begin with the end in mind.

I'm still a work in progress. Hope I have imparted some simple tidbits of info & help you in a way.

Cheers!

Hi Joseph,

As they say below, it is not allowed to modify the approved document unless authorized as required by contract.

First obtain the latest updated schedule from the main contractor. In the same schedule you will have to input your updates.

Suggests that you will provide the main contracor with your updates and let them input the data you provided with their schedule.

Kindly clear to me that when you say "updating" ... you input the actual dates and necessary percentage of completion?
If this is the case then there is an out of sequence activities if you say that start and finish dates is push by other activities upon updating.

Regards,

Raymund

Paul,

Usually if your work will begin after the completion of works by others, that completion date will be indicated as milestone date so it will only push your activity once the other contractor didn't achieve that completion date.
