EXECUTION
EXAMINATION
Examine substrates for conditions detrimental to installation of fixed audience seating.
Proceed with installation only after unsatisfactory conditions have been corrected.
INSTALLATION
Comply with manufacturer's installation instructions and approved shop drawings.
Anchor support standards securely to substrate with at least two anchoring devices recommended by manufacturer.
Place standards in each row laterally so the standards at the aisle will be in alignment.
Vary width of seats and backs as required to optimize sightlines and comply with the ADA Standards for row and aisle widths.
In curved rows, install standards to form smooth radius, without breaks or angled chords
Attach components to standards with sufficient flexibility to compensate for convergence of seats toward the center.
ADJUSTING
Adjust seat mechanisms to ensure that seats in each row are aligned when unoccupied.
Repair minor abrasions and imperfections in painted finishes with a coating that matches factory-applied finish; replace units that cannot be repaired to unblemished appearance.
Replace upholstery fabric damaged or soiled during installation.
