Specific work plans and procedures shall be completed by the owner’s representative prior to the commencement of any remedial activities.

B. Disturbance or dislocation of mold containing, or contaminated materials may cause mold spores to be released into building's atmosphere, thereby creating a health hazard to work persons and building occupants. Consistent with mold remediation work, Contractor shall appraise all of it’s workers, supervisory personnel, subcontractors and consultants who will be at job site of the seriousness of the hazard and of proper work procedures that must be followed.

1.2 REMEDIATION AREAS

A. Work shall be performed in the following sequence at each of the areas referenced in Paragraph 1.1.(4)(a) and all other areas fungal growth is discovered:

1. Walls, floors and ceilings other than those to be removed within the work area shall be covered with least 1 layer of six mil, flame retardant polyethylene sheeting and sealed with duct tape from the floor to ceiling deck. T-grid from drop ceiling will have to be removed and cleaned.

2. Critical barriers shall be installed over all openings to the work area consisting of at least 1 layer of six mil, flame retardant polyethylene sheeting and sealed with duct tape. An airlock shall be attached to work area.

3. HVAC diffusers to the work area shall be de-energized or disconnected and sealed with at least 1 layer of six mil, flame retardant polyethylene sheeting and duct tape.

4. Install HEPA filtered negative air pressure equipment in the work area, exhausting to the exterior of the building to create a negative pressure enclosure at all work areas.

5. Owner’s representative shall inspect work areas prior to start of removal and cleaning activities. Upon removal of the wall and all porous materials within the wall cavity and work area, the work area and adjacent wall should be inspected by a third party to determine if additional mold growth exists. If visible growth exists, the adjacent wall should also be removed. All components and surfaces within work area and sheeting shall be HEPA vacuumed and wet wiped.

BLDG. 577 CULINARY ARTS – MOLD REMEDIATION 028500 – 2

6. All adjacent surfaces to the microbial compromised areas shall be thoroughly cleaned, scraped, scrubbed and/or sanded to completely remove all mold contamination. Following the abatement of all mold-contaminated surfaces the entire work area shall be thoroughly cleaned and disinfected using a detergent solution and a wet/dry rag system.

7. The work area shall pass both a visual inspection and microbial clearance sampling following abatement and cleaning activities.

8. Following successful visual and microbial clearance sampling, surfaces adjacent to the remediation zone and any remediated surface to remain shall be disinfected by the proper use of an EPA Registered Disinfectant, Fungicide and Cleaner.

9. The work area shall be allowed to thoroughly dry, the abated surfaces will then be sprayed or wiped with a coating of fungicidal disinfectant/sealant such as Anabec X-90 or equivalent. Application shall be as described by the manufacturer.
