Addendum No. 1
Issue Date: October 6, 2020
Project: Interior Renovations
The Betty Hardwick Center
The following are additions, deletions, clarifications, or corrections to the Specifications and Drawings
and shall become a part of the Contract Documents.
Drawings
Item #D1 Sheet M0.1 - General Notes – Updates made to General Notes J, K, Q, R, and CC.
Item #D2 Sheet M1.0 - Mechanical Plan
• Duct and takeoff size changes due to updated air flows to each room
• Return air ducts added to RTU-13 and 14
• Changed the corner office return air silencers to a model U device due to
clearance issues above the door frame
Item #D3 Sheet M2.0 - Keyed Notes – Updates made to Keyed Notes 1 and 2.
Item #D4 Sheet M3.0 - Mechanical Schedules and Details
• Updated air device schedule due to duct and takeoffs size changes
• Added a new model U return air silencer device for office that didn’t allow for
the standard model Z
• Updated Rooftop Unit Return Detail to show that the bottom of the return air
duct shall be installed flush with the bar joists, and the grilles will be duct
mounted on the side of the duct.
• Updated model of EF-2 to account for higher static pressure drop within the
duct work
