Z2DA--Replace Building 1 Heat Exchanger

Page 3 of 3 Project No. 542-25-112 CONSTRUCTION Replace Building 1 Heat Exchangers THIS OPPORTUNITY IS AVAILABLE ONLY TO SERVICE-DISABLED VETERAN-OWNED SMALL BUSINESSES. Service-Disabled Veteran-Owned Businesses (SDVOSB) must be certified by The U.S. Small Business Administration Veteran Small Business Certification (VETCERT). This acquisition is conducted in accordance with FAR Part 36 & 14, Invitation for Bid. This project replaces the two steam-to-water heat exchangers (HX) which provide heating water to the building, the steam control valves for each of the heat exchangers, and the steam condensate pump. Heat exchanger work: It is anticipated that the HX must be lowered to facilitate future maintenance without major piping impact. Thus, a revised configuration is needed to facilitate easy maintenance. A Conceptual Sketches document, utilizing marked-up photographs, is included in the documentation to provide a recommendation for this reconfiguration. Steam control valve work: The existing control valves are located at the top of the mechanical room space above the pit and are not very accessible. In this project, the steam control valves must be relocated to be accessible to maintenance. A Mechanical Room Pit Part Plan is included in the documentation to show a recommendation for where to locate the control valves and where to route the steam pipe to facilitate maintenance as well as proper straight lengths of piping in and out of the control valves. Steam condensate pump work: The existing condensate pump is pressure powered. The new condensate pump is to be electric. The existing flash tank is abandoned and unusable. It must be replaced with a new ASME vessel. Additionally, existing condensate return paths are convoluted, following original paths, and may not be draining properly. This project reroutes the condensate return in the mechanical room to be direct to the new flash tank in the pit. A Mechanical Room Overview Drawing shows the entire mechanical room
