Dear All,
Any one can guide me regarding the preparation of schedule of Piping Fabrication in Fabrication Shop.
For example when we prepare a schedule for a pressure vessel we add activities like
1. Plate cutting aas per drawing
2. Rolling
3. Fitup
4. Rerolling
5. Welding
7. Nozzels cutting
6. Fitup of ends
& so on this is information belongs to limited drawings say 01 to 10, but in Pipie fabrication we will based on each dia inch of pipe in each drawing or we will go general as cuuting, fitup, welding, rt & so on.
I want to prepare a shedule for pipe fabrication of 75000 dia inches & these dia inches related to 500 drawings, if i will go for each drawing separatly the total taskes may go above 20000, which are some what difficult to manage.
Regards,
SHAH

Oldest first- 0Brennan Westworth ·For that quantity of pipe spools I would recomend that you first break it into packages according to the requirements of your construction programme and fabricators capability. 500 drawings should equate to about 25 to 50 packages.
Then set up schedules (table format) by drawing to track the progress of fabrication with % complete recorded for material delivered, processing (or cutting), fitup, welding, testing and delivery to site (or however you see fit). You can drive S Curves from this data and use it to update the high level activities in your schedule for the piping packages. - 0Tahir Naseem PMP, CCE ·Dear Shahzad
The best way to develop the detail schedule for 75000 dia inch plan you first of all need to develop a WBS to lowest level it may be like area wise/unitwise then seprate by material such as CS / SS / AS etc, then you can further break up to small bore and large bore and extra large bore such as less or equal to 1.5", 3" to 24" and more than 24" so on. Now at this stage is better to cevelop the package of no of isometrics and set up schedule to monitor the progress and develop s-curve
