EXECUTION
EXAMINATION AND PREPARATION
If preparation is the responsibility of another installer, notify Architect in writing of deviations from manufacturer's recommended installation tolerances and conditions.
Do not proceed with installation until substrates have been properly prepared and deviations from manufacturer's recommended tolerances are corrected. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
Commencement of installation constitutes acceptance of conditions.
INSTALLATION
Install in accordance with manufacturer's written instructions and recommendations, including but not limited to the following.
Schedule pours so as to install the metal safety nosings quickly before the ' initial set' of the concrete occurs.
Puddle the concrete and tamp safety nosing to insure proper concrete formation around the anchors.
Remove protective tape, if used, upon completion of installation.
Close area after pour; permit no use for 24 hours.
CLEANING AND PROTECTION
Cleaning: Clean treads and nosings as recommended by manufacturer. Remove scuff and heel marks prior Substantial Completion.
Protection: Protect installed work from damage due to subsequent construction activity on the site.
