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.
