Commomwealth Ave. Fullerton, CA 92833 Tel: 714-635-5350 Fax: 714-525-6083 Email: request info Web: www.advancedequipment.com [ Click Here ] for additional information. Advanced Equipment Corporation was established at Bellevue, Washington in 1957 as a designer, manufacturer, and installer of operable walls. The company was incorporated in the State of Washington in 1958 and moved to California shortly thereafter. AEC was established to manufacture operable walls and has been a designer and fabricator of that product since its founding. Today, AEC continues in the quest for greater efficiency and better value for our customers. Our premier ALPHA® operable walls offer superior, field tested sound stopping ability, resistance to earthquakes, are incombustible, and have demonstrable ease of operation and durability. ALPHA® panels are furnished with 10 and 20-year warranties. AEC also offers several tracks with 5 and 10-year warranties that do not require a service contract and do not exclude normal wear. AEC makes extensive use of electronic technology to assist our customers with preliminary design assistance, as well as improve product design and manufacturing. DWspec will produce error free specifications and drawings in DXF format. Drawings are dynamically created based upon customer input without the need for downloads. The customer needs only a browser to properly configure and specify an AEC operable wall.

Testing Methodology: Testing of the installed operable wall(s) for noise isolation shall be performed according to ASTM E-336-05, determined by ASTM E-413, and rated for not less than the NIC indicated in this specification. Wall(s) are to be adjusted and fitted to comply with NIC test method requirements.
	** NOTE TO SPECIFIER ** Delete performance level not required. Use with mandatory testing.
			1.	Performance Level: 10 percent fund retention.
			2.	Performance Level: 20 percent fund retention.
		D.	Corrective Measures:
			1.	Should an operable wall fail to achieve the specified NIC, wall supplier shall have 60 days to make corrections/adjustments and pay for cost of retesting. This procedure shall be followed until all walls achieve the specified NIC.
			2.	Should a wall fail to achieve the specified NIC after corrections and/or adjustments and it is determined that failure is not due to sound flanking through surrounding building construction then the wall supplier, at its own cost, shall replace the operable wall with a new wall that is capable of achieving the specified NIC and pay for the cost of testing this wall.
			3.	Written results of the field sound tests shall be submitted to the Owner.
	PART 3	EXECUTION
	3.1	EXAMINATION
		A.	Do not begin installation until substrates have been properly prepared.
		B.	Verify at site, conditions affecting work of this Section and obtain accurate dimensions of opening, grades and levels and arrangements of all embedded anchorage. Report discrepancies between drawings and field conditions to Architect prior to commencing work. Commencing work shall indicate acceptance of conditions and surfaces underlying or adjacent to work of this section.
	3.2	PREPARATION
		A.	Clean surfaces thoroughly prior to installation.
		B.	Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
	3.3	INSTALLATION
		A.	Install in accordance with manufacturer's instructions. Installation shall be performed under the supervision of a factory approved installer in strict accordance with the manufacturer's printed installation manual to ensure satisfactory operation and performance.
		B.	Install operable walls with all adjoined panels functioning in true and plumb alignment to form an effective operating sound barrier.
	3.4	PROTECTION
