PART 3    EXECUTION
3.1	EXAMINATION
A.	Site Verification of Conditions:
1.	Examine surfaces scheduled to receive furred out or directly attached acoustical units for unevenness, irregularities and dampness that would affect quality and execution of work.
2.	Do not proceed with installation of acoustical panels until unacceptable conditions are corrected.
B.	Environmental Requirements:
1.	Do not install acoustical panels until building is closed in and HVAC system is operational.
3.2	INSTALLATION - GENERAL
A.	General: Do not begin installation until materials sufficient to complete an entire room are received and are ready for installation.
1.	Field cut acoustical panels as required, in accordance with manufacturers recommended procedures and equipment.
2.	Install acoustical wall panels in accordance with quantity and lay-outs as shown on the architectural drawings.
3.	Acoustical wall panels shall be adhesively or mechanically mounted in accordance with manufacturer's recommendations and/or as detailed on the drawings.
B.	Manufacturer's Instructions:
1.	Comply with the instructions and recommendations of the acoustical panel manufacturer.
2.	Install materials in accordance with governing regulations, fire resistance rating requirements and industry standards applicable to work.
3.3	PANEL MOUNTING
A.	Adhesive Mounting: Panels are to be installed per recommended adhesive instructions. 
B.	Magnetic Fasteners: The magnetic fastener is applied to the panel before shipment. Permanent spanport is required.
C.	Hook and Loop Fasteners: The loop side of the fastener is applied to the panel at time of shipment. The hook side is attached to its mate, and when installing, the tape backing is removed and the panel is positioned on the wall. Permanent support is required.
D.	Concealed Splines: Panels with concealed spline attachment are provided with kerfs along the edges of the panels. The spline then inserts into one panel and is mounted onto the wall. Adjoining panels are inserted into the remaining half of the spline.
E.	Mechanical Clips: The panel clips are mounted onto the panels at the time of shipment. The wall clips are installed on the wall at the location established by the position of the panel clips or wall bars.
F.	Impaling Clip: The impaling clips are screwed directly to the wall with the prongs extending outward. The glass fiber acoustical panel is positioned and pressed firmly onto the clip. Locking Adhesive is recommended with this clip mounting.
3.4	CLEANING
A.	Clean exposed surfaces of acoustical panel to comply with manufacturer's instructions for cleaning.
B.	Remove and replace tiles, which cannot be successfully cleaned and repaired to permanently eliminate evidence of damage.
3.5	PROTECTION
A.	Protect installed work from damage due to subsequent construction activity, including temperature and humidity limitations and dust control, so that the work will be without damage and deterioration at the time of acceptance by the Owner.
