I do agree that suspension may have larger impact on schedule than the number of days it lasted .....for example.......after domoblization ......re mobilization ,itself may take some time to restart the work .....
I, personally think that ,beside suspension ....remobilization can also be introduced as a delay event ...if required..
I would start precisely where you started, with the calendars work days, 90% it would end there, 10% it should be expanded to mimic other real life situations within the limits of CPM. Maybe I would not follow the owners request and insert a Work Stoppage Activity "working" under a Work Stoppage Calendar, so that it shows, of course there are other ways but I like the idea of breaking the rule that All Activites were stopped.
I believe the very first step for a scheduler to prepare a claim is to listen carefully to the jobsite supervisors, by assuming it is just a 90% event he might miss some relevant issues.
I have not found another place where discussion is so open minded, I got to 100% accept your explanation; I was not expecting less, yes keep challenging us.
I thought it was not rubbish, just a bucket of cold water.
By the way it is nitrogen for an MRI machine to keep the superconductor functioning, for pipe purging should be hydrogen, argon or other specialty gas. I just noticed I inverted the references in my prior posting.
Thank you for your intersting comments particularly:
"Yes, everywhere you can find examples where delaying/stopping an activity for a short period of time might have an impact greater that the delay/stoppage."
Please tell us how you would set a work stoppage delay into a construction programme so as to get the full results of the delay impact - particularly where ALL activities have stopped.
By the way my role as a moderator is to keep the forum tidy and the thread rules applied.
It does not prevent me talking rubbish from time to time (I am bi-lingual fluent in both English & Rubbish)so I need people like you to open up debates and prove me wrong.

I believe the statement that a work stoppage is exactly the same as a non workday holiday is farsighted.
You are ruling out the effect this might have in the total job duration when the stoppage impacts the schedule by other means. Yes even through delivery activities, can you believe it?
My wife, who doesn’t know what a CPM schedule is, knows. She does scheduling with other tools that fit best her needs. As a Supply and Distribution Manager (now a Distribution Chain Manager, a term that seems to be in fashion) often she is faced with the fact that clients by delaying their orders by a single minute might impact the delivery by a week.
If a client needs helium for their MRI machine in such a hurry they cannot wait for the next week, because the shipping ports in mainland USA do not send a barge every other minute, she would have to coordinate the shipment to be by air, believe me after 911 it is an issue within a US jurisdiction. A similar situation might occur when a pharmaceutical needs nitrogen in a hurry to purge some pipelines. These are expensive gases you cannot store for long, these got to be produced, some locally others in the mainland, and distributed within a limited period of time.
Yes, everywhere you can find examples where delaying/stopping an activity for a short period of time might have an impact greater that the delay/stoppage.
Young people even when realizing a moderator statement is wrong they might feel intimidated, they would rather avoid discussing in public their dissent. As a moderator your expressions might be interpreted by many as correct, maybe moderators should abstain from commenting and limit themselves to keep order.
First define the root cause of the stoppage event. after defining and you concluded that the event is beyond the contractors hand and does affect the critical path, send a correspndence to the client and inform them that the work stoppage has an incured delay and cost implications.
Just a thought.
Mr. Mike,
I do understand that setting a two day stoppage into a nonworking days will invalidated cost implications. Correct me with this if Im wrong, and please further elaborate of why putting as a nonworking days.

Remember there is more than meets the eye. Talk to the field supervisors’ maybe the impact is more than just the time of stoppage.
For some activities, loss of continuity might mean increasing your impacted activities remaining duration.
If resource loaded the correct application of resource leveling should take care of issues regarding availability of resources specially when date dependant. Like availability of a specialized crane now not available until two weeks instead of in two days.
You are at the right place, brainstorming is for free.

Cal4endars are rarely used by planners to their full potential.
I always put the potential weather into a new start programme and then adjust for actual weather in the progress reports.
I once did a full EOT and Acceleration claim using nothing but calenars and work patterns.
Another trick is to set up the contract programme on an 8 hour day for the Client and issue construction programmes to Sub - Contractos on a 9 hour day - just make sure you do not get them mixed up.
As for charging - I make a very good living out of planning and delay analysis but of course to PP it is all Pro Bono.

If the event lasted for two days, and the client already issued you the notification to stop the work, then you can proceed with submitting a request for two days extra and the cost associated with that.

The issue is very much clear to me ....
I do agree that suspension may have larger impact on schedule than the number of days it lasted .....for example.......after domoblization ......re mobilization ,itself may take some time to restart the work .....

Hi Rafael
At no time have I "called you out of the topic".
All I did was ask how you would put a work stoppage into a programme to create the effects you described.
Please dont do a "Charleston" on us.

Precisely that is where I do not agree with you, it is not necessarily an issue to be limited by calendars.
As your attitude is to call me out of this topic I will call me out of PP, you are the Moderator, and you establish the rules.

Hi Rafael
If you look again at post 10 I think you will find that I have covered most aspects of this thread.
Look out for a new thread on the use of calendars.

Hi Bill
A work stoppage is exactly the same as a non workday holiday.
By putting it on the calendar it affects all activities that are planned to work in this period.
It will reduce float and - where there is zero float - extend the completion date.
It is relatively easy to calculate the cost of the stand down by reference to the resource histograms.
There is an argument that re starting activities will have slower production rates for an hour or two.
This can be replicated by changing thw work patterns for the day when work restarts.

Hi Khawaja
Show the work stoppage as a Non Work Days on your callendar.
A different calendar will be needed if not all work was stopped.
