W4.2_SSG_3D Work Breakdown Structure of Topside of Floating Production Unit for EPCI Contract


PROBLEM DEFINITION

We are now in the end of Concept Definition phase where the contract of EPC-I work will be delivered. One of the contracts requirements in the contract coordination procedure is to develop a structured breakdown of work which is measureable and well organized.

DEVELOPMENT OF FEASIBLE ALTERNATIVES

To accommodate the contract coordination procedure and project controlling purpose, Work Breakdown Structure is developed. Better WBS is when it can be seen from many point of view. It means, once we develop a WBS, different stakeholder can see the project from his / her point of view.

DEVELOPMENT OF OUTCOMES FOR EACH ALTERNATIVE

Referring to NORSOK Standard Z-014, there is at least 3 different point of view to the WBS. The point of view are from “Product Breakdown Structure”, “Standard Activity Breakdown”, and “Code of Resource”.

Figure 1. 3D  WBS Point of View

Produc Breakdown Structure (PBS), is a WBS that project product is the highest level of the WBS. In this case, it’s Topside & Utilities.

Standard Activity Breakdown(SAB), is a WBS that Standard Activity is the highest level of the WBS. In this project, SAB category is divided as per Table.1 below.

Figure 2 . Standard Activity Breakdown of Topside of FPU

Code of Resource (COR), is a WBS that Code of Resource is the highest level of the WBS. In this project, COR category is divided as per Table.2 below.

Figure 3. Code of Resource of Topside of FPU

SELECTION OF CRITERIA

A well Work Breakdown Structure must include all the work needed to complete the projects. Besides that, It must have, at least, below characteristic.

ü  It is defined output not process.

ü  It is hierarchical, top-down decomposition of output.

ü  It’s lower level output is input to higher Level.

ü  Normally, resources is included in the WBS

ü  Theoretically, NO decomposition limit.

 

ANALYSIS FOR THE ALTERNATIVES

Above WBS must include all the scope of work in the project, hence:

  1. The WBS must be able to be used as a control to breakdown scope of work.
  2. WBS must cover all the deliverables to complete the the projects.
  3. In the Lumsump contract, WBS is also used as earn value representation breakdown.
  4. One WBS is dedicated to one scope of work.
  5. One WBS is performed by one or more activities.
  6. WBS is part of the contract documents.
  7. For additional scope, dedicated WBS will be developed.

SELECTION ON THE PREFERRED ALTERNATIVES

Below are selected alternative for Topside part of FPU Projects:

Figure 4, Project Work Breakdown Structure from PBS point of view

Figure 5, Project Work Breakdown Structure from Standard Activity point of view

Figure 6, Project Work Breakdown Structure from Code of Resource point of view

 

PERFORMANCE MONITORING AND POST EVALUATION RESULT

Above Work breakdown structure is consistent until the end of the project unless new additional scope is defined. In that case, dedicated WBS will be developed.

Those 3 point of view above is not fixed and can be changed depend on the stakeholder need.

  1. OK, AWESOME posting and now that you have fulfilled all three criteira, you can claim your Earned Value for this posting-
    1) You PHYSICALLY did the work
    2) The work was in SUBSTANTIAL CONFORMANCE to the technical specifications and
    3) You fulfilled all the contractual requirements (the “shall clauses”)

    There is no reason why you cannot or should not be getting 4 or 5 stars for EVERY blog posting from this point forward….. Take your time and do it right the FIRST time….
