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 Development, 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 Omniclass 3D WBS as one of alternative for this project
Development of The Feasible Alternatives
OMNICLASS is a strategy for classifying the entire built environment. It is designed to provide a standardized basis for classifying information throughout the full facility life cycle from conception to demolition or reuse, and encompassing all of the different types of construction that make up the built environment.
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).
Development of The Outcomes For Each Alternative
Following are 15 inter related Omniclass table:
- Table 11 – Construction entities by Function
- Table 12 – Construction entities by Form
- Table 13 – Spaces by Function
- Table 14 – Spaces by Form
- Table 21 – Elements (includes Designed Elements)
- Table 22 – Work Results
- Table 23 – Products
- Table 31 – Phases
- Table 32 – Services
- Table 33 – Disciplines
- Table 34 – Organizational Roles
- Table 35 – Tools
- Table 36 – Information
- Table 41 – Materials
- Table 42 – Properties
All of the table above can be plotted as a parralel axis of the three main axis of the project cube
- GBS : Table 13, Table 14, or Table 21
- PBS : Table 11, Table 12, Table 23, or Table 36
- ABS : Table 22, Table 31, or Table 32
- OBS : Table 33 or Table 34
- RBS : Table 35
- Task : Table 41 or Table 49

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 Omniclass table as reference.

Performance Monitoring and Post-Evaluation of Results
Based on exercise above, we found that omniclass WBS is compatible with 3D WBS. Omniclass table is providing more detail WBS and more valuable to run the project smoothly. The challenge is how to define what is WBS table fit to our project. Since the omniclass table was created based on infrastructure industry, it is slightly difficult to use the WBS correctly for Oil and Gas Project. We will try to compare this method with NORSOK Standard Z-014 on the following blogs.
