Phase II - Scope of Work - Lead Paint Abatement Irerracon <br />Grand Theatre ■ 21 Lamar Avenue, Paris, Texas <br />June 4, 2012 ■ Terracon Project No. 94107645 <br />Individually seal ventilation openings in walls (supply and exhaust), wall mounted fixtures, <br />connectors, and other wall and floor openings into the Work Area with polyethylene <br />sheeting at least 6 mil in thickness, taped securely in place with adhesive tape. <br />Maintain seal until Work, including work of Final Clearance Section, is completed. <br />Exercise care in sealing active lighting and other fixture to avoid melting or burning of <br />sheeting. Seal the perimeter and seams of sheet plastic barriers with adhesive tape. <br />Cover floor drains to prevent liquids from any source entering the sewer system. <br />Provide leak protection to floor surface adequate to prevent water leaks to floors below the <br />Work area or to areas outside the containment. <br />Complete Pre-Cleaning and Decontamination procedures before proceeding beyond this <br />point. <br />Primary Barrier (first layer), install as necessary for the type of Containment Construction <br />required: <br />Floor: One layer of clear polyethylene sheeting, 6 mil thick minimum. Cover floor, <br />including Critical Barriers, and turn polyethylene up walls at least six inches (6"). Form a <br />sharp right angle bend at junction of floor and wall so that there is no radius which could <br />be stepped on causing the wall attachment to be pulled loose. Both spray-glue and <br />adhesive tape seams in floor covering. <br />Wall and/or Ceiling: One layer of clear polyethylene sheeting, 4 or 6 mil thick as <br />indicated. Cover walls and/or ceiling in Work Area, including Critical Barriers. Support, <br />as required to maintain barrier throughout Project Duration. Attach edge of sheeting at <br />least eight inches (8") away from lead material. Seal perimeters and joints including the <br />floor covering joint with adhesive tape. Do not locate seals at wall to wall joints. <br />Secondary Barrier (second layer), install as necessary for the type of Containment <br />Construction required: <br />Floor: One layer of clear polyethylene sheeting, 6 mil thick minimum. Overlap first barrier <br />and turn polyethylene up walls at least twelve inches (12"). Utilize the same installation <br />procedures as Primary Barrier. Locate seams in top layer at a minimum of six (6) feet <br />from, or at right angles to, seams in bottom (first) layer. Install sheeting so that this top <br />layer can be removed independently of bottom layer. <br />Wall and/or Ceiling: One layer of clear polyethylene sheeting, 4 or 6 mil thick as <br />indicated. Overlap and attach second layer of polyethylene eight inches (8") beyond first <br />layer, as close as possible to lead material without causing disturbance of material. <br />Install sheeting so that this top layer can be removed independently of bottom layer.
