f. All work shall be performed in accordance with the applicable safety and health standards, the contract, and these specifications. Adequate ventilation shall be provided and maintained at all times during use of monomeric materials and solvents. Fans used for ventilating shall be explosion proof. If necessary, respirators that filter organic fumes and mists shall be worn. All contaminated materials such as wipes, empty containers, and waste material shall be continually deposited in containers that are protected from spillage. Spillage shall be immediately and thoroughly cleaned up and disposed of in accordance with applicable regulations.

3.1.2 Repair Concrete.

a. The Contractor shall install a protective coating/lining solution to all surfaces of the pit to protect against infiltration and exfiltration. Chosen material shall be a two‐component moisture insensitive, highly adhesive, chemical resistant, 100% solids, high strength and reinforced structural‐grade epoxy. Prior to coating/liner application, the Contractor shall remove and patch roughly 200 square feet of loose, delaminated and weak concrete.

b. The Contractor shall use all means and precautions necessary to insure the safety of the occupants and protection to the existing building infrastructure (to include but not limited to the sump pump, piping, and conduit) during demolition and surface preparation operations.

c. The Contractor shall install necessary barricades and enclosure to contain particles and vapors from migrating into other areas of the building, and to protect and control construction traffic. Efforts shall be made to create a barrier that effectively prevents air-borne pollutants from moving from the work area to another adjacent area within the building. To increase the effectiveness of the barrier, physical barriers can be used, such as plastic sheeting.

d. The Contractor shall be responsible to remove all of the accumulated water from within the pit prior to proceeding with any work. Provisions will be made with “Boiler Plant” personnel to ensure water is NOT drained into the pit after work commences.

e. The Contractor shall completely remove all oil, grease, dust, curing compounds, waxes, laitance and other contaminants from all horizontal and vertical surfaces to come in contact with the material. Contractor shall prepare concrete in accordance with the manufacturer’s recommendations, and using acceptable mechanical means as necessary to obtain clean, sound and profiled concrete. Contractor shall prepare concrete in accordance with SSPC-SP 13/NACE No. 6 “Surface Preparation of Concrete.”

f. The Contractor shall remove all rust, corrosion, and bonded concrete from any exposed reinforcing steel. As a minimum, the steel shall be cleaned to remove all loose or poorly bonded debris that would affect bond between the repair material and reinforcing steel. To prevent flash rusting, the Contractor shall use a recommended holding primer. It is estimated that this will be required for 60 square feet of the overall repair.

g. After the concrete has been prepped and cleaned, it shall remain in a clean, dry condition until the repair has been completed. Any contamination, including oil, solvent, dirt accumulation, or foreign material shall be removed by additional cleanup.

h. Surface and material temperatures shall be kept within the requirements for the selected product during and after product application, until product is cured.
