In the Construction Manager as Agent model, the CM works for the owner in much the same way as the architect would, providing consultation and management services, usually for a fee. The owner contracts directly with whatever subcontractors are required to complete the scope of work. The CM may, if the owner chooses, manage the subcontractors—and the project in general—but contractually, the CM does not sit between the owner and subs.

In this relationship, the CM typically provides estimating, scheduling, sequencing and constructability services to the owner, as he would in an at-risk relationship.
