About this file
This is a bid set drawing package prepared for Columbus State University in Columbus, Georgia, for the River Center Cooling Tower Replacement project under Contract Number CSU-11-26. The project involves the replacement of existing cooling towers with new equipment and associated HVAC systems modifications on the roof of the River Center facility. The bid set, dated July 9, 2025, includes mechanical and electrical demolition and installation work, with a bid set expiration date of June 30, 2026. The project engineer is NBP Engineers, Inc., located in Macon, Georgia. The drawings specify two new cooling towers (CT-1 and CT-2) to replace existing units, modifications to condenser water piping systems, electrical disconnects and conductors, and structural steel support systems. The scope includes removing existing cooling tower equipment, basin systems, conduit penetrations, and related infrastructure while retaining specified structural elements and existing service platforms.
The bid set contains detailed mechanical and electrical schedules, including pump specifications for condenser water circulation showing 1,050 feet of head at 1,750 RPM for both existing pumps, with cooling tower manufacturers listed as Marley and Evapco. The new cooling tower units are specified as AXS Series 3000 NC models with 95 degrees Fahrenheit maximum wet bulb ambient conditions and 7 kilowatt electric basin heaters. Design conditions include outside air at 97 degrees Fahrenheit dry bulb/76 degrees Fahrenheit wet bulb and inside conditions at 75 degrees Fahrenheit and 55 percent relative humidity. All existing conduit and conductors are to be reused, with specific notation that penetrations through the roof must be sealed upon removal of equipment. The project involves coordination between mechanical and electrical systems with references to existing building infrastructure and verification requirements in the field.
