RFP 2019-02 - REPLACEMENT/REFURBISHMENT OF HVAC SYSTEM AND CONTROLS

The City of Dauphin is accepting proposals for the replacement and/or refurbishment of the existing HVAC system and associated controls, for Dauphin City Hall, 100 – Main. St. S., Dauphin, Manitoba. Dauphin City Hall was constructed in 2000/2001 and the HVAC system consists or a single Engineered Air rooftop unit that has been modified to operate as an HVAC system with a StarCom 95 control system.
The system has had many problems from its initial installation. One of the largest issues is that the system “fights itself” during shoulder seasons; continuously overheating or overcooling parts of the building and then trying to rectify. The second largest issue is the comfort level throughout the building as a result of this and the initial design. Supplemental heat is provided in many of the offices but is not integrated into the control scheme. Large communal areas and the lobby do not have supplemental heat and therefore staff are resorting to the use of portable heaters. A new or refurbishment of the existing HVAC unit(s), and advanced control systems are needed to rectify these issues.
