EPC s -curve

What information would you like to produce an S-curve for, and what info do you have available?

Steven,
All I am having now is a total budget which is distributed on three major disciplines, EPC. P holds the about half of the total budget. On D I have monthly expenditures but of until one month ago. My project is still under design and only few equipments are procured. Construction is gonna begin after few months.
I need a an illustrated explanation for producing standard overall s curve. Are there different kinda s-curves possible?
Can I start begining with these info?
cheers

Nar Thap,

For EPC Project you have to come up with common matrix for each activities.

It could be cost, it could be man-hours, it could be duration.

This will all depend on the situation you are in.

In my case, if the progress curbe will be needed ami ami, or ASAP, I will use durations. If someone will disputes specially non planners, i will just tell them if they can do it in say one day, then let them do it.

The point we have to be reasonable.

Duration as common matrix is very easy. In resource dictionary, assign a Resource "D". export all activities and assign and open the wk1 file. Assign resource D in all activities. Use import and update. All activities will have resource D.

Next

How to assign quantities for each resources at each activities.

TO BE CONTINUED...........

In very simplistic terms.

An activity on your plan has attributes of cost (or other factors) and time.

When you combine the cost of an activity and the time over which it will be performed, the result is a certain amount of cost distributed over a certain amount of time.

The addition of all these distributions by time period, produces the periodic cost distribution for the project, and the cumulative addition of each time period produces the cost profile for the project, which is generally graphically represented by an s-curve.

In continuation to my post #4.

Use global change to place budgeted quantities for each activities with resource D.

"if resouces is D, then Budgeted Quantity equals duration"

Run the change to take effect.

What you have now are activities loaded with resouce D with Budgeted Quantity equals to amount of Durations.

The nest steps is to come up with overall progress S-curve, Engineering phase Progress S-Curve, Procurement Phase S-Curve and Construction Phase Progress S-Curve.

This Progress Curve is only for baseline program

To be continued

Hi Nar & All,

Charlie is right, you can have duration as your calculated units for producing S-Curve(s), but this should be supported by labor-material-equipment work/delivery duration analysis and using mutually agreed productivity rates. Still, cost and manhours units are normally used for S-Curve(s). Possibly manhours for "E", cost for "P" and cost-manhours for "C".

On Charlie’s post no .4, instead of exporting all activities to dbf/xls, it is easy to just select all activities in P3 then click "Insert" menu then select "Resource Assignment". From the resource drop-down list, assign a resource to all selected activities.

You could provide 4 S-Curves as per Charlie’s advise.

Cheers,

I use:

For engineering Deliverables / hour accomplished.

For Procurement: Procuremente management: Hours/ Requisitions.
For Delivery: Cost (mainly).

For Construction: Cost / measured units in each and every discipline for instance concrete m3 for civil works, welding inches or kg of piping for mechanical erection and so on.
