PART 3 - EXECUTION

 

3.01   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” (6 mm). Similar structural support is needed for the stacking bay(s) and any upper track leading to it. Structural support for lateral loads such as forced entry, etc. must be provided.

 

It is recommended that all building dead loads be applied to the header prior to installing the unit. 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” (6 mm). 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 floor, not only in the rough opening area but also in the single action panel swing areas.

 

C.  Installation of units constitutes acceptance of existing conditions.

 

3.02   Installation

A.  Install frame in accordance with supplier’s recommendations and installation Instructions.

 

B.  Installer to provide anchorage devices and to securely and rigidly fit top head track in place, level, straight, plumb and square. Install frame in proper elevation, plane and location, and in proper alignment with other work.

 

C. Install panels, handles and lock set in accordance with supplier’s recommendations and installation instructions. D.  If necessary, adjust hardware for proper operation.
