PART 3 EXECUTION

3.01 EXAMINATION
A. Examination and Acceptance of Conditions per Section 01 70 00 and as follows:

1. Carefully examine rough openings with Installer present, for compliance with requirements affecting Work performance.
   a. Examine surfaces of openings and verify dimensions; verify rough openings are level, plumb, and square with no unevenness, bowing, or bumps on the floor; and other conditions as required by the manufacturer for readiness to receive Work.
   b. Verify structural integrity of the header for deflection with live and dead loads limited to the lesser of L/720 of the span or 1/4 inch (6 mm). Provide structural support for lateral loads, and both wind load and eccentric load when the panels are stacked open.
   NOTE: Prior to installing Nana Wall, it is recommended that all building dead loads be applied to the header. Allow a reasonable amount of time for the dead load’s effect on the header; only then can the building’s live load be used to meet the above requirements of L/720 or 1/4 inch (6 mm). If this is not done, both dead and live loads need to be considered.

2. Proceed with installation only after unsatisfactory conditions have been corrected.

3.02 INSTALLATION
A. General: Install Folding Glass Partition system in accordance with the Drawings, approved submittals, manufacturer’s recommendations, and installation instructions, and as follows:

1. Properly seal around opening perimeter to reduce sound infiltration from surroundings.
2. Securely attach anchorage devices to rigidly fit frame in place, level, straight, plumb, and square. Install frame in proper elevation, plane, and location, and in proper alignment with other work.
3. Wood Finishing: Field finish wood under Section 09 90 00, Painting and Coating; seal and finish promptly after installation and prior to exposure.
4. Install panels, handles, lockset, gasketing and other accessories in accordance with manufacturer’s recommendations and instructions.

3.03 FIELD QUALITY CONTROL
A. Field Tests and Inspections per Section 01 40 00 of the following:
1. Verify the Folding Glass Partition system operates and functions properly. Adjust hardware for proper operation.
B. Non-Conforming Work: Repair or replace non-conforming work as directed by the Architect; see General and Supplementary Conditions, and Division 01, General Requirements.

3.04 CLEANING AND PROTECTION
