PART 3 - EXECUTION
3.1 ERECTION
A. Because of the large dimensions involved and the weight and movement of the
panels, verify the structural integrity of the header such that the maximum deflection
with live and dead loads is limited to be the lesser of L/720 of the span and 1/4”.
Structural support for lateral loads (both wind load and eccentric load when the panels
are stacked open) must be provided. It is recommended that all building dead loads be
applied to the header prior to installing the NanaWall. If so and if a reasonable amount
of time has been allowed for the effect of this dead load on the header, then only the
building’s live load can be used to meet the above requirements of L/720 or 1/4”. If not,
both the dead and live loads need to be considered.
B. Examine surfaces of openings and verify dimensions; verify rough openings are level,
plumb, and square, with no unevenness, bowing, or bumps on the floor.
C. Installation of units constitutes acceptance of existing conditions.
3.2 EXAMINATION
A. Examine areas and conditions, with Installer present, for compliance with requirements
for installation tolerances and other conditions affecting performance of the Work.
B. Proceed with installation only after unsatisfactory conditions have been corrected.
