This document is written with the sole purpose of soliciting bids for HVAC Replacement Phase #3 at Chase Middle School. For purposes of definition: "Board" in this document refers to The Board of Education, Unified School District No. 501, and Topeka Public Schools. Base Bid: a. Installation of new supply and return heating hot water piping systems & control elements to enable existing heating coils in existing Air Handing Units (AHUs) to function, as well as serve future Variable Air Volume (VAV) boxes per the construction documents. i. New piping mains will originate from a set of existing pipes located above a hallway on the west side of the school's cafeteria/multi-purpose room. ii. From there piping will branch out to connect to existing heating coils in three existing AHUs located in mechanical rooms throughout the building. These coils currently do not have any piping connections. iii. Along these piping mains, tees with isolation valves will be provided periodically to allow for future piping branches with minimal shut downs or drainage to the main heating system. These piping branches will provide hot water to heating coils in VAV boxes in future phases. b. Provide additional pressure sensor and control sequences to allow for the existing VFD controlled hot water pump to modulate with system load. i. Three heating hot water control valves and supporting control sequences for the heating coils on AHU-1, AHU-2, & AHU-3. ii. In the existing reverse return heating piping, a control valve and supporting control sequence will be required to balance the flow to the remaining hydronic heating system. iii. Three additional differential pressure sensors in the new heating hot water piping to control flow to the heating coils on AHU-1, AHU-2, & AHU-3. c. Provide a minimum flow bypass pipe, control valve, & control sequence to maintain minimum flow through the chiller. i. Reconfigure an existing chilled water connection to AHU-4's cooling coil into a chilled water bypass pipe to maintain the chiller's minimum flow. d. Provide a new chilled water piping connection to AHU-4's cooling coil. e. Controls will be bid directly to the owner by control contractor. Controls will be by Control Services Company with no equivalent. Control contractor will be responsible to furnish control valves, to be installed by Mechanical Contractor. f.
