5 2.03 DESIGN CRITERIA A. Provide acoustical isolation to prevent transmission of sound and vibration generated by [mechanical and electrical equipment] [or] [ ] to adjacent building areas. This requirement includes isolation of all items passing through the floating floor. B. Acoustically isolated floor to provide predictable system natural frequency for common concrete wearing surface of [9 Hz for 100 mm (4 )] [7.5 Hz for 150 mm (6 )] [6.5 Hz for 200 mm (8 )] thick floating slab. C. 15% maximum strain or 8 mm (.30 ) maximum deflection for [30 Durometer isolators under max. recommended load of 57 kg (125 lbs.)] [50 Durometer isolators under maximum recommended load of 79.4 kg (175 lbs.)]. D. Normal design load calculations for rubber isolators and layout to be based on the weight of the floating floor slab plus the weight of equipment, machines, fixtures and constructions supported by the floating floor plus 25% of the specified live load. E. Maximum design load calculations for rubber isolators and layout to be based on the weight of the floating slab plus the weight of the walls and fixtures supported by the floating slab plus 100% of the specified live load. F. Durability of rubber isolators to be 50 year minimum without significant degradation of performance. Part 3. Execution 3.01 EXAMINATION A. Before installation, examine alignment, smoothness and evenness of substrate. Notify [Contractor] in writing if substrate does not comply with requirements of acoustic subfloor manufacturer. If concrete structural slab is to be waterproofed or sealed, ensure coating is sufficiently cured prior to installation of panels. If coating remains tacky or exhibits excessive grip, cover with minimum 3 mil polyethylene sheeting to facilitate installation of the panels. Panels with attached isolators must be allowed to move freely when tapped into position. B. Verify items provided by other trades are properly installed. C. Commencement of work will imply acceptance of substrate conditions PREPARATION A. Ensure installation area is free of all debris, broom clean and dry. 5 HI-SEP FLOATING FLOOR

6 B. Brush or vacuum walls approximately 305 mm (12 ) up from structural floor to ensure walls are sufficiently clean to receive perimeter isolation board adhesive INSTALLATION A. General 1. Install acoustic floating floor strictly in accordance with manufacturer s printed instructions. 2. Co-ordinate work with related work to avoid rigid contact with the building. B. Perimeter Isolation Board 1. Install perimeter isolation board at sidewalls and around penetrations such as [piers,] [columns,] [pipes,] [drains,] [and] [electrical items] [ ]. 2. Ensure height of perimeter isolation board exceeds height from concrete structural substrate to top of concrete wearing surface by at least 50 mm (2 ). 3. Adhere perimeter isolation board using a single bead of good quality polyurethane based panel adhesive located at approximately the middle of the board. Press board firmly to wall and tape vertical joints including corner joints, and horizontally around acoustic subfloor/perimeter isolation board interface. Use construction sheathing tape or duct tape for isolation board joints at these locations and at penetrations. C. Acoustic Subfloor Panels 1. Following acoustic subfloor manufacturer s written instructions, install preengineered and prefabricated subfloor panels according to layout drawing[s]. If necessary, layout drawings may include specific locations in the system where certain tagged or labeled panels must be placed. These panels will be pre-fitted or allocated to be site-fitted with extra pick-up isolators for predetermined placement of heavy equipment or other point loads. 2. Using rubber mallet and/or spare piece of wood, tap panels into alignment, taking care not to damage panel edges. Make sure panels stay square and tight to adjacent panels. 3. Once panel is aligned, place 4 staples at each panel joint to help prevent panel misalignment using an air stapler to ensure staples are well seated and flush to surface of panels.

7 3.04 CLEANING 4. As the work progresses, ensure all factory installed point load rubber isolators are in place. If additional site installed pick-up isolators are required, staple isolator rubber ears to panel bottom or fasten with single screw and washer through the cylindrical void in isolator. Cut away fiberglass insulation to expose underside of panel prior to fastening isolator. 5. After panels are in place, install 3 mm (1/8 ) thick hardboard Perimeter Gap Seal Type AF-PGS at any location where subfloor panels are not in direct contact with perimeter isolation board. Finish by sealing seams with construction sheathing tape. 6. Cover OSB subfloor panels with minimum 6 mil polyethylene sheeting. Lap sheet edges minimum 75 mm (3 ) and tape watertight while ensuring application is free of wrinkles and fishmouths. 7. Place concrete wearing surface and reinforcement, including curing and finishing agents as specified in Division 3 of the specifications. Do not allow concrete [and] [rebar] to touch structure or base building. 8. When placing concrete, ensure concrete does not build up in one spot and overload subfloor panels. Spread each load over a dozen or so panels. Do not roll concrete carts directly over acoustic subfloor panels. Use temporary wood planking for heavy wheeled or concentrated loads. 9. After concrete has cured, use utility knife to cut excess perimeter isolation board at wall edges and penetrations. 10. If required by local codes, caulk top of perimeter isolation board. 11. Sound isolate drains. A. Upon completion of work, remove all materials, equipment and debris from site. B. Leave work area and adjacent surface in condition acceptable to [Consultant] [Architect] [Engineer]. C. Protect uncured concrete with markers, barriers or signs WASTE MANAGEMENT AND DISPOSAL A. Separate waste materials for [reuse] [and] [recycling] at nearest used building materials facility. B. Divert unused caulking, sealants and adhesive materials from landfill through disposal at hazardous materials depot. 7 HI-SEP FLOATING FLOOR
