Problem Recognition, Definition, and Evaluation
The new project has been established with name Water Pre Treatment Package Project. The Project objectives are:
- To ensure there is no solid particles carry over from water well to WTP
- To increase potable water production capacity
- To reduce time for backwash activity
- To Prevent RO membranes damage due to contamination in its feed water
During FEL-0, Operation people defined that to achieve all of project objective above, we shall install pre-treatment unit at Upstream of WTP. This week blog, we will create NORSOK Standard Z-014 3D WBS as one of other alternative for this project
Development of The Feasible Alternatives
NORSOK Standard is a system for coding of cost and weight estimates and as-built/experience data which has been recognized as standard cost coding system (SCCS). It is developed by the three Norwegian Oil Companies Norsk Hydro, Saga Petrolium, and Statoil with purpose to standardize and specify cost coding system.
3D WBS is a theory that tell us that WBS includes three main dimension: the zones (GBS), the products (PBS), and the activity (ABS). The Fourth Dimension is the organization (OBS) which is extended from Resources (RBS). It was found by Jean-Yves Moine to establish all of the dimension into WBS and manage cost and time linked together.
Development of The Outcomes For Each Alternative
The NORSOK standard comprises 3 sets of complementary sub-coding system named:
- PBS (Physical Breakdown Structures)
- SAB (Standard Activity Breakdown)
- COR (Code of Resources)
Selection of Criteria
The WBS includes the following characteristic:
- Is Product-oriented
- Includes all work
- Support historical cost collection for future cost estimating purposes
Analysis and Comparison of The Alternatives
The Following will be used for WBS development:
- The WBS should represent the complete list of deliverables for the project
- Deliverables should be decomposed to the level of detail needed to estimate the effort required to obtain them
- Ensure That each WBS element has a single point of accountability
- All significant reporting events (such as review meetings and monthly status report) should be included in the WBS
- WBS development is critical to scope management. Revisit the WBS often and expect to iterate its development
- Keep a list of activities that are out of scope. Confirm scope with stakeholders often by reviewing the WBS and the list.
- All Projects require a project management WBS element to ensure that the work of planning, tracking, and reporting is managed
Selection of The Preferred Alternatives
We will try to create 3D WBS with using NORSOK Standard as reference.

SAB – Standard Activity Breakdown

COR – code of resource

We are need one more dimension to make 3D WBS. So, we make one more WBS which is not defined on NORSOK that explain the area of work.

Performance Monitoring and Post-Evaluation of Results
NORSOK Standard Z-014 is giving us more detail and valuable WBS that can help project team to develop better cost and schedule. It is classifying the WBS into 3 sub code PBS, SAP, COR. We will compare all of the WBS alternatives with using Multiattributes decision Method on the following blogs.
