 it aims to make this analysis easy and
 extensible with parametric definition of
 the process. To that end, it combines
 several new approaches.

 One of the major roles of construction
 management on site is defining and
 orchestrating resources. Labour
 crews use various tools, equipment,
 and materials to perform the work.
 Site supervision directs crews and
 equipment to perform tasks in a
 specific sequence and at a specific
 target production rate. To reflect this
 type of construction resources, we
 built an agent-based simulation model
 for resources, where each individual
 crew and major equipment is an agent
 with specific goals and policies. By
 providing simple and natural policies
 for resources, realistic construction
 practices can be achieved.
