Project Information Sheet
Type: Wastewater
Category: Infrastructure
Project Manager: Hira Raina
Fund: 465 Wastewater Management Fund
Sub-Fund: 300 Wastewater Infrastructure Subfund
Project Coordinator: Dan Hammons
This project replaces the heating, ventilation, and air-conditioning systems in the Primary Building and the Laboratory Building at the City's Water Pollution Control Plant. The HVAC systems in
both buildings are old, energy inefficient and becoming increasingly expensive to maintain.
The cost relates to the complexity and the range of the projects. For the Primary building, there are five "package units" that need to be evaluated for replacement, potentially with fewer units, but
still to cover a mix of uses including: large electrical equipment, temperature-sensitive control panels, and working spaces (offices, training room, etc.). For the lab, the HVAC replacement system
needs to be upgraded to meet code requirements for air exchanges for worker safety, and the heating and cooling systems are under review for the best alternative for repair/replacement. Project
funding will cover both design and construction. Final design should be completed by December 2008. Bid documents will be prepared and bidding is anticipated to commence early CY 2009,
allowing construction to be completed in the summer of 2009.
The condition of existing buildings will be addressed in the strategic infrastructure plan (SIP). However, these buildings will be used extensively until the SIP recommendations can be implemented
in five to ten years and these replacements are necessary. The useful life expectancy of a new air-conditioning system would be 20 years.
This project will be completed in conjunction with 827010 (Primary Roof Replacement), because of their interrelated impacts.
Project Evaluation and Analysis
The current HVAC systems of the two buildings are inadequate to provide proper air recirculation rates and are costly to maintain due to age. The project alternatives recently completed will
implement the required improvements and new technologies to rectify current deficiencies. The project will be bid with two bid alternatives, allowing the most cost effective strategies to be
implemented.
Fiscal Impact
This project replaces existing infrastructure with no significant fiscal impact. Utilizing energy from the plant's heat loop system will provide overall operational efficiency and cost savings for the
system. Future replacement will be incorporated in the Strategic Infrastructure Plan (SIP).
