The Center and Administrative Wings are outside of this project’s scope.

2. Work activities will include, but not limited to:

a. General Conditions – See Division 01 specifications

b. Provide a Registered Roof Consultant (RRC) certified by the Roof

Consultants Institute, or a Registered Professional Architect or Professional Engineer who will perform a roof condition assessment and investigation and provide a report with findings and recommendations prior to any roofing work beginning.

c. Properly Phase the project in coordination with the Location to minimize impact to research operations.

d. The new roof system must be designed and attached to the parameters specified (See SOW) and validated by applicable Factory Mutual (FM) testing.
