The old 16 division (now many more) CSI system with its many sections represents the final work breakdown by individual components. This is helpful when you are looking for completeness or trying to describe, price or specify those components, but in many ways and for many tasks this fine detail is an impediment. For example, a window section in a masonry wall involves Divs 4, 5, 7, 8, 9 for masonry, lintel, flashing, window, and finishes respectively. It is very difficult to think about the window detail in terms of those five divisions, but the detail fits very nicely into one of the Assembly Divisions in this system - Exterior Closure.
- establishing a typical details library
- organizing / delegating design work
- planning construction document sheet content
- estimating preliminary costs
- structuring bid packages
- developing a construction schedule
When using Assembly Divisions, a project is divided into the following 12 categories.
- Exterior Closure
- Interior Construction
- Conveying Systems
- Mechanical Systems
- Electrical Systems
- General Conditions & Profit
- Special Construction
- Site Work
