40 NORTH PEARL STREET ALBANY, NY

August 24, 2017 NOTE: This Addendum forms a part of the Contract Documents. Insert it in the Project Manual.

Acknowledge receipt of this Addendum in the space provided on the Bid Form. HVAC WORK SPECIFICATIONS 1. Page 236500-4, Subparagraph 2.02 J.1.: Delete this Subparagraph in its entirety and replace with

the following: “1. Electronic water level control package shall have five (5) stainless steel water level

sensors (one (1) high level, one (1) high level alarm, one (1) low level, one (1) low level alarm and one (1) ground) with a NEMA 4x enclosure mounted in a cleanable Schedule 40 PVC external standpipe with slow closing solenoid valve(s) and "y" strainer(s). Components shall be field mounted. Valves shall be sized for 25 psi minimum to 125 psi maximum pressure. a) Provide electronic level control for basins in each cell allowing for level control

whenever the adjacent cell basin/unit is off line.” 2. Page 236500-4, Subparagraph 2.02 L.5.: Delete this Subparagraph in its entirety and replace

with the following: “5. Units shall be provided with a Vibration Cutout Switch to protect the fan and drive from

damage in the event of excess vibration” HVAC WORK DRAWINGS 3. Revised Drawings: a. Drawing No. M-001, noted “REVISED DRAWING 8/23/17” accompanies this

Addendum and supersedes the same numbered originally issued drawing. ELECTRICAL WORK DRAWINGS 4. Revised Drawings: a. Drawing Nos. E-001 and E-101 noted “REVISED DRAWING 8/23/17” accompany this
