Prepares evaluation of the A/E contractor's performance.
The COTR is usually the Branch Manager of the Branch in Design Division where the project is assigned.
Contractor: In this guide, the construction firm contracted by EFA CHES to build a particular project. The

stakeholders can include the end users, the activity and the outside agencies that have approval rights to the

Preservation Office (SHPO), Maryland Department of the Environment (MDE), National Environmental Policy
