About this file
This is Addendum 4 to the contract specifications for HVAC and Plumbing Upgrades at International Studies Elementary School, issued by the Dougherty County Board of Education in Albany, Georgia, prepared by Andrews, Hammock & Powell, Inc. The addendum, dated June 20, 2022, modifies the original specifications and drawings from May 20, 2022, and must be acknowledged by all bidders on the Bid Price Form to avoid disqualification. The changes address instrumentation and control requirements for HVAC systems, including modifications to thermostat and temperature sensor installation specifications in Section 230900.
The addendum specifies that newly installed thermostats and sensors shall be mounted at 4 feet 6 inches above finished floor unless otherwise noted, with existing installations permitted to remain at current heights. Thermostats in classrooms are prohibited from having locking metal covers, while those in common areas such as corridors, cafeterias, and media centers shall be installed behind locking covers unless otherwise noted. Additional requirements include the installation of two space temperature sensors in the kitchen's walk-in cooler and freezer with alarm functionality if temperatures rise above setpoint for more than five minutes, and DDC system monitoring of space temperatures in data rooms and areas served by standalone ductless split systems and PTACs with alarm signals sent to the owner if temperatures exceed specified setpoints.
