ACTION REQUESTED:
Title
Communication from the City Manager and Director of Public Works with a Request to APPROVE a CONTRACT with HUNZEKER SERVICE AGENCY, INC. for a SOLE SOURCE PURCHASE of a TRANE TRACER CONTROL FRONT-END UPGRADE at City Hall for a Cost of $69,000.
Body
BACKGROUND: The City Hall building has two temperature control systems: the Andover Control System and the Trane Tracer Summit System. The Andover system currently controls the building's air handling units and the variable air volume boxes (VAV Boxes). The wireless temperature sensors, VAV controller, and work station are all beginning to fail, making system maintenance difficult. The Andover system's wireless sensors also have batteries that need replacement every 6 months and, since they have already begun to fail, are being replaced with Tracer wireless sensors. The Trane Tracer Summit controls the hot and chilled water systems, which do not communicate efficiently.
Currently, the Building's systems operate in a 24/7 mode due to the sequence of operations issue. Since the building's main system is a Trane system, Facilities staff recommends replacement of the failing Andover Control System with Trane components and attached is that proposal. Hunzeker Service Agency is the only local Trane supplier.
This new system will allow the controllers to communicate through one front-end, for greater efficiency. In addition, the new system is web-based and will allow Facilities staff to schedule, receive alarms, trend all control points, and view system graphics remotely, from a PC or iPad. The front-end system also will operate in a more efficient mode to reduce the building's gas and electric consumption, while giving a better level of comfort to staff and visitors.
FINANCIAL IMPACT: Funding for this project is budgeted in the 2014 Facilities Operations capital program Project CB1400 Account #401-8401-551.50-02.
