W16_GW_OmniClass and 3D WBS on Pipeline Installation

  1. Problem Recognition, Definition and Evaluation

    A company will install pipe 6” CS Schedule 40 gas pipeline from the gas Gathering Station A to Plant B. Is the use of OmniClass 3D WBS can be applied to this project?

  2. Development of the Feasible Alternatives

    OmniClass is a means of organizing and retrieving information specifically designed for the construction industry. It consists of 15 hierarchical tables, each of which represents a different facet of construction information or entries on it can be combined with entries on other tables to classify more complex subjects. (OmniClass, 2014)

    3D WBS is based on three main dimensions: Zones Breakdown Structure (ZBS), Products Breakdown Structure (PBS) and Activity Breakdown Structure (ABS). (Moine, 2012)

  3. Development of the Outcomes for Each Alternative

    The 15 inter-related OmniClass tables are: (OmniClass, 2014)

    1. Table 11    : Construction Entities by Function
    2. Table 12    : Construction Entities by Form
    3. Table 13    : Spaces by Function
    4. Table 14    : Spaces by Form
    5. Table 21    : Elements (includes Designed Elements)
    6. Table 22    : Work Results
    7. Table 23    : Products
    8. Table 31    : Phases
    9. Table 32    : Services
    10. Table 33    : Disciplines
    11. Table 34    : Organizational Roles
    12. Table 35    : Tools
    13. Table 36    : Information
    14. Table 41    : Materials
    15. Table 49    : Properties

    The tables above can be described in terms of the 3D WBS models as follows: (Moine, 2012)

  4. Selection of a Criterion

    Characteristics of the WBS:

    1. WBS defines output
    2. WBS is hierarchical
    3. One WBS level’s output is an input to the next higher level.
  5. Analysis and Comparison of the Alternatives

    By using Omniclass tables as reference, 3D WBS for the project is as follow:

    1. Zone Breakdown Structure (ZBS)

    2. Product Breakdown Structure (PBS)

    3. Activity Breakdown Structure (ABS)

    Based on the above, it appears that OmniClass and 3D WBS are compatible.

  6. Selection of the Preferred Alternative

    OmniClass tables give a more detailed WBS and can be applied to this pipeline installation project.

  7. Performance Monitoring and Post Evaluation of Results

    OmniClass is specifically designed for the construction industry, so use the tables to be suitable for oil and gas projects is something that is rather difficult. In the next blog post, it tries to apply the 3D WBS using the NORSOK Standard Z-014 on the pipeline installation project.

  1. AWESOME posting, Pak Gideon!!!

    But be sure to update your material to reflect Jean Yves’s latest thinking. I have convinced him (Jean Yves) that the work of physicist Garrett Lisi https://www.ted.com/talks/garrett_lisi_on_his_theory_of_everything suggests that the correct or most appropriate model or shape of the WBS is a star tetrahedron- http://3d-wbs.blogspot.com/2014/06/part-120-tetrahedron-projects-like.html

    Very interesting and cutting edge material……….

    Keep up the good work and looking forward to seeing more on this interesting and timely topic…
