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.
DEVELOPMENT OF OUTCOMES FOR EACH ALTERNATIVE
There is no theoretically WBS level of detail standard. It depends on the project complexity. In this project, WBS will be divided in to 5 levels i.e.
Level 1. Project, overall progress will be on this level
Level 2, Function, To define the phasing of each facilities i.e. Project Management, Engineering, Procurement, Fabrication / Construction, Mechanical Completion, Transportation, Offshore Hook-up and Commissioning, Projects Close Out.
Level 3. Facility, to cover breakdown of project facilities i.e. Topside
Level 4, Component, to define component work of each facility.
Level 5, Component, To cover each discipline applied in each component.
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:
- The WBS must be able to be used as a control to breakdown scope of work.
- WBS must cover all the deliverables to complete the the projects.
- In the Lumsump contract, WBS is also used as earn value representation breakdown.
- One WBS is dedicated to one scope of work.
- One WBS is performed by one or more activities.
- WBS is part of the contract documents.
- For additional scope, dedicated WBS will be developed.
SELECTION ON THE PREFERRED ALTERNATIVES
Below are selected alternative for Topside part of FPU Projects:
Figure 1, Project Management Breakdown
Figure 2, Engineering Breakdown
Figure 3, Procurement Breakdown
Figure 4, Fabrication & Mechanical Completion Breakdown
Figure 5, Transportation, Offhshore Installation, and Close Out
PERFORMANCE MONITORING AND POST EVALUATION RESULT
Above Work breakdown structure is consistent until the end of the project unless new additional scope is define. In that case, dedicated WBS will be developed.
