WBS for EPC project (engineering-procurement-contstruction)

Ideally, you should never develop WBS on your own. It should always be a team effort corresponding to concerned disciplines or specialties. Like for example: You were asked to develop a process flow diagram when you were never a process engineer. So how could you be able to do that? However, reality in construction projects is so difficult to understand or managed. And just ultimately resulting to whatever they can just do best and fast (even copying other works that were totally different from what they intend to do), only to satisfy some stupid contract requirements or not defaulting the contract. So still wondering why most construction projects (if not all) fail? Or always spending beyond budget and always late?

hi,

Simple WBS

Enggineering 

    > Submissions (Drwgs) 

    > Review and Approval (Drwgs)

Procurement 

   > Submissions (Material/Technical) 

   > Review and Approval (Material/Technical) 

   > P.O 

   > Fabrication/Manufacturing Cycle 

   > Onsite Deliveries

Just for the sake of emphasis,  your WBS  for engineering and procurement  in a typical  Oil and gas environment may  look like this:

(1) Process, Mechanical, E & I Design

(2) Location (pipe racks, Flare, inlet manifolds, utility area,etc)

(3) Work items (pipes, KOD, Tank, heaters Pumps, valves, etc)

(4) Deliverables(P&IDs, Plot plans, Isometrics, etc)

 

Procurement

(1)Discipline ( Civil/structural, M&E, Instrument)

(2) categories ( local, Foreign)

(3) Shipment (Discuss methology & procurement sequence with experts in procurement Dept)

(4) Work item (equipment, valves, pumps, specialists of diff trades).

Note that process leads in engineering while  Civil structural activities take precedence in most construction activities.

wbs = work breakdown structure. the clue is in the name. How do your engineering & procurement departments breakdown their work?

 

They might break it down like the following example, they might not. Speak to them to find out

 

1) Engineering

2) Discipline (civ, mech, elec, etc)

3) Sub-discipline (groundworks, paving, buildings, etc)

4) Area / workfront / whatever you call it

5) Deliverable type (calcs, drawing, survey, etc)

 

1) Procurement

2) Discipline

3) Procurement Item (rebar, piling contractor, etc)
