Bid project PW1504 - City Hall HVAC and Digital Control Upgrade. |
City staff, as well as the contracted maintenance provider for the City, have identified the need to upgrade the Building Automation System (BAS), and portions of the HVAC systems at City Hall due to the age and reoccurring and increasing operational costs of the current system. The current control system for these devices and equipment is no longer supported and is subject to failure
The current 40-ton roof top units are at the end of their projected life cycle. These roof top units were installed around 1999. The average life cycle for this equipment is 15 years. Replacement of these roof top units will lower overall operational and energy cost as well as increase their reliability.
In addition, the city commission room has been subject to inadequate and uncontrolled conditions (humidity/lack of heat) due to the current HVAC configuration. The current system provides for an unreliable, inconsistent and inefficient system.
The base bid for this project is for the installation of a new Building Automation System (BAS). This platform will also allow control of other locations to immediately include the Community Health Building and upon completion of the new House Hold Hazardous Waste facility (HHW). This upgraded system will allow for annualized utility savings, as well as operational and maintenance cost savings. This upgrade will allow for more reliability and increased comfort level for the facility. There are three (3) additional alternates included in this RFP.
