Subject: Architect's Supplemental Instructions #<strong>017</strong> – <strong>Railing</strong> <strong>Extension</strong> Detail<br />
Dear Wilson:<br />
The enclosed <strong>ASI</strong>-<strong>017</strong>, <strong>Railing</strong> <strong>Extension</strong> Detail, supplies a solution to a safety concern<br />
associated with the location of the FCUs in the Stairs.<br />
We are concerned that occupants (students) could hurt themselves on the corner of the FCU<br />
units given their close location to the stair tread. Refer to the attached sketch, ASK-051, for<br />
our solution.<br />
All contract documents and other directives remain unchanged except the drawings and<br />
specifications added to, revised, deleted or clarified by this Instruction.<br />
The instructions to the constructor are as follows:<br />
1. Provide the rail extension detailed in attached sketch ASK-051 at all locations where<br />
the FCU is less than 44” from the stair tread.<br />
2. Paint the rail extension(s) to match the existing railing.<br />
Cordially,<br />
