In this article, we will focus on a specific type of tank, external floating roof type with single deck and internal pontoon. Sample Work Breakdown Structure (WBS) for an external floating roof type designed tank construction project can be decomposed as the following. As tank erection work is only focused, detailed WBS for foundation work is intentionally left at level 1. It is just to show that foundation is required for the above ground storage tank.

Dear ,
ReplyDeleteThank u very much for sharing wonderful template
Dear reader, you are welcome.
DeleteHello to all,
ReplyDeleteIt would be very useful for a junior planner like me if you could share with us your thoughts about how to prepare the WBS for the piping work in a plant or refinery. Should we proceed by height, by area, by phase? I have to planify the construction and assembly on site of a 1200-line chemical plant.
Thank you for your reply
Dear reader,refer to new post on WBS for the piping work.
