Phases are one of the ways to organize the standard database into similar types of work or tasks. There can be two levels in the phase hierarchy.

Group phases (divisions) - classify phases into work-related groups.
Example: The Sitework group phase might include Asphalt Paving, Fine Grade, and Landscaping phases.

 Phases (subdivisions) - classify items into work-related tasks.
Example: The Asphalt Paving phase might include Type H Asphalt material, Crusher Run Base, and Asphalt Primer items.
