Procurement Problem

Will they be procured as one item? Will they be designed as one item? Will the be installed as one item? Will they be commissioned as one item?

No.

So why would you want to plan them as one item?

Why putting as one item ? Procurement start date and end date is sufficient isn't?

When the delivery of the items is more than one unit to be consumed on different areas the correct way to model the effect of non timely deliveries is by using consumable/nonrenewable resources.

Activity logic is not enough, even if you create a separate activity for every item it will not do it; say 200,000 bricks delivery activities will not do it, as soon as you have a single brick on site the installation can start but at some point might be interrupted.  

You cannot model the effect using regular/renewable resources.

For this reason for many decades such functionality for consumable resources have been available. When you have hundreds of such resources, hundreds of partial deliveries and hundreds of activities competing to use these resources it can become quite complicated to manage the schedule using manual adjustments.

I started using this functionality over two decades ago with Microplanner V6 but suspect have been around a few additional decades before, it is nothing new. Learn to use this functionality if delivery of materials matter. 

Hi Moutaz

As Rafael noted,"if delivery of materials  matters" then it is essential that every procurement item is individually planned and the ROS ( Required On Site ) is establised. For bulk materials you could  detail the requrements per fase or section.

Hi Moutaz

There are four stages for material procurement following design.

1. Approval of the material by the Engineer.

2. Place order and set up delivery sequences.

3. Manufacture & delivery - allow for any Factory Inspection Tests (FAT) by the Engineer - there should be as many sections as there are workfronts on your programme.

4. Take delivery to laydown areas and deliver to any particular workfront.

These stages should all be set ALAP.

Stage 1 & 2 can be a single bar linked FS but they must then be linked to work sections in stage 3. 

I doubt if your 81km of pipeline is all in one single bar - it should at least be in sections between the three tanks so link stages 3 & 4 FS to each work section starting with "stringing out".

You will then have a responsive procurement programme linked to progress on site - it will also show the immediate affect of any client delays.
