Deliverable Activities

Omar,



What if you want to link Issued for Review drawings to Get Construction Permit, and link Issued for Construction drawings to Request for Proposal, and link Approved for Construction drawings to Start Construction. All of this for the diferent work packages. You would need to have everything inside your schedule without using an external database.

An interesting discussion but I have always worked within systems where, with large numbers of deliverables the detail (Level 4) control of engineering deliverables and their weighted progress/forecast completion dates is managed within a separate database, under the operation of the Lead engineers. The connection to the schedule is a manny (deliverables) to one P3 discipline activity ’engineering work pack’ which is related to an MR or a construction workpack. The connection is the P3/P6 activity ID. Progress is rolled up in the data base with a % progress and the latest forecast completion date of all deliverables in the EWP gives the driving date for the issue of the MR/Work Pack. This method allows effective sequence & time management without creating huge schedules.

Hi Berli

If i follow activity steps, will the S curve be generated same as we do in excel.





with regards

When i am creating a deliverable schedule.. do i need to give for each each deliverable 4 separate activities( like start,IFR,IFD & IFC) under each deliverable.... how to go about it...

say if i have got 1000 deliverables then 1000 Wbs has to be created & 4000 activities will be generated

& how to assign resource for that deliverables



has anybody done this.



sunil

When using activity steps, First set % type as physical & click on the check box(Project window) for ACTIVITY PERCENT COMPLETE BASED ON ACTIVITY STEP.



Now say your deliverable is P&ID

Add P&ID as activity, define its step as

IFR

IFD

IFC

Define the step weightage for IFR, IFD & IFC

Then enter the % complete for the step, if IFR is completed then check in for completed.



I hope this may be clear to you.

This is now possible in P3 e/c by using activity steps.

Hi,



Yes, you may have a group of deliverables that differ with each other. At the planning stage, your deliverables maybe grouped as datasheets, procedures, P&ID, Calculations, Study Report, Plan & Details, etc. with equivalent or common duration and you may define a corresponding resource curve for each group.



Another possible way is through the use of "Steps". The new features in P3 e/c. I never tried it actually but it seems will work at the same case.



Those who using "Steps" already may share some experience in doing scheduling. Anyone?

Hi Berli,



I am sorry did not answer immediately, but spent some time in medical care.



You either have to detail your activities, or split them by resource, from my experience, it is easier to detail them, but ensure you add things like approvals and issudued for construction to your schedule, and then do not fall asleep, make sure you record every revision in your program, and ensure the client/managing contractor or whatevevr is aware of it, in time, early warning,

Hi,

You could still maintain your 1000 activities by defining a Resource Curve to spread its cost or resource unit over the duration of activity.



Add then Modify the resource curve value based on your deliverables weightage and distributed over time.



Once defined, assign this resource curve to each activities. Your S-Curve will correctly reflect the cost or resource distribution now.

Hi,



Basically for example lets say your are casting a large concrete slab, this is normally done in a checkerboard fashion, in other words, in square of lets say 5m X 5m. For the fist half of the panels, you you would need shuttering, and the balance not, in my opinion a microschedule is a schedule drawn up in detail to determine the duration of all the panels in detail, to determine the duration of the whole slab, which can then be shown as a single activity, in the main schedule. In other words, it is detail scheduling to determine main activity durations.



Off-sets are used in resourcing, where different resources are used in thze execution of a single task. Lets say you are building a simple wall, ie excavate for foundation, cast foundation, brickwork. The sfirst resource would excavator, lets say one day, secondly concrete lets say one day, then curing, no resources say two days, and lastly brickwork say 4 days. The main activity, "build wall", would have a duration of 8 days. the resourcing would be as follows:

excavator duration 1 day offset 0 day

concrete duration 1 day offset 1 day

brickwork duration 4 days offset 4 days

Try drawing this on paper, and you will understand it.



Hope this helps.

Vladimir,



Even if I breakdown the activities to more detailed one but primavera progress is much ahead than the conventional way of computing in excel spread sheets using milestones.

To: Philip



On your posts, I need elaboration on the following words:



- micro schedule

- off-sets



Please kindly explain further as its new to me. Thanks!

Hi,

If you are resourcing an activity with four resources, which it sounds to me you should be doing, you should us off-sets. But as Vladimir rightlyy states rather split up the activity, although off-sets would also work and give you a better picture

Why not to create 4 activities instead of 1?

I also have the same problem now but I think it is impossible to apply those progress calculation in P3. Usually, P3 calculate based on pro-rata method (Original OD - Remaining OD/Original OD).



Any reply is highly appreciated.
