Project Redwood Sciences Laboratory Roof Replacement

General Information

1.0 Scope of Work

The existing Built-Up Roof (BUR) has deteriorated causing the roof to leak into the interior of the building and needs to be replaced. The work consists of furnishing all labor, supervision, equipment, transportation, and materials for the installation of the new BUR roof system. Prior to the installation of the new roof systems, inspect the existing roof substrate for signs of deterioration or damage.

Notify the COR if repairs are needed before proceeding with the repairs and the installation of the new BUR roof system.

The Contractor should carefully review all sections of the specifications to completely understand the work and all constraints including schedule, and material requirements.

The Contractor is encouraged to proceed in an orderly and expeditious manner according to a construction schedule developed by the Contractor and mutually agreed upon with the Contracting Officer prior to the commencement of the work. All work is to be done in strict accordance with all building codes and regulations, plans and specifications, and subject to the terms and conditions of the contract.
