Planning by level (WBS)
Thursday, March 13th, 2008Somewhat of a different blog this week.
More of a discussion in planning methodology. In particular Work Breakdown Structures and what level should activities sit in the WBS for multiple rise buildings.
I start this blog by explaining that there are different ways and reasons for sorting activities within a WBS, and understand that others may disagree with JCA’s methodology, but I will explain JCA’s methodology and reasons for and let others make their mind.
Example - the activities for forming, construction and pouring a slab should go in the level of the building that it describes. eg:
- Basement “Slab on Grade” should be in the WBS heading called Basement,
- Ground Suspended Slab should be in the WBS heading called Ground Level (or sometimes refered as Podium Level),
- Level 1 suspended slab activities should be in the WBS heading called Level 1,
Not all planners see it this way (for what reasonable reasoning alludes us). ie We know of some planners and builders who put Level 1 suspended slab activities under the heading of Ground Level…Although the props and framework for forms are indeed temporarily in the Ground to Level 1 Zone (and ultimately hold up the Ground Level fitout works) we beleive stongly that those activities surrounding the construction of the permanent designed element should be listed in the WBS code of that Level, in this case Level 1.
Therefore slab for level 1 and associated props etc should be listed under level 1.
OK glad to get that off my chest now..and of course happy to receive comments on this.





Well it’s Busy in JCA’s Project Planning office currently.
