No. 323-0130-7204-06237 Equipment Improvement Fund -- Roofing / HVAC Improvements CITY HALL 215 Church Avenue P0.Box 1130 oshk°sh,Wisconsin City of Oshkosh 549903 03 1 -11330 OIHKOIH TO: Honorable Mayor and Members of the Common Council FROM: Jon Urben, General Services Bureau Manager DATE: April 17, 2012 RE: Convention Center Chiller Replacement Bid BACKGROUND The two 80 ton rooftop chillers now in operation at the Oshkosh Convention Center were installed in 1985 and are 27 years old. The ASHRAE average service life of an outdoor chiller condenser is 20 years. These chillers remove the heat from liquid in the HVAC system and service the majority of the Center's A/C needs. In recent years both chillers have required numerous and excessive repairs. Because of their age it is now more cost effective for a full system replacement vs. ongoing individual repairs. Working with our mechanical engineer consultant, Purchasing prepared specifications seeking vendors to replace these chillers, pump and control systems to maximize their energy efficiency and utility savings. Bid requests were advertised on our online NovusVendor system and in the local paper. Bids were received on April 13, 2012. The bid tab is attached. ANALYSIS Bids were analyzed by the engineer consultant and Purchasing. It was our consensus that the low bid received from EGI Mechanical Inc. ($179,616) met the bid specifications. This project will provide several energy efficiency and utility saving improvements to the Center's HVAC system including: replacement of the two chillers (projected to improve energy efficiency by 20%); installation of variable frequency drive (VFD) pumps (projected to reduce pumping energy usage by 30%) and installation of a new direct digital control (DDC) controls (projected to save an additional 3-5% in utility savings from tighter controls on temperature usage and scheduling). Combined, these improvements are projected to provide an estimated 25% energy savings of the system. In addition, the DDC changeover will minimize future pneumatic control replacement costs and allow Facility Maintenance staff to better monitor the Center's HVAC systems thereby improving troubleshooting and operational efficiency. These same DDC controls and monitoring are already in place for City Hall, the Safety Building and the Seniors Center. FISCAL IMPACT The fiscal impact of this bid is $179,616. This project will be funded from the Roofing/HVAC Improvements project (A/N#: 323-0130-7204-06237) listed in the 2012 CIP Property Improvement Fund. By adding engineering fees (+$3,500) to this project and factoring in an estimated $10,000 in Focus on Energy incentives we anticipate the total cost of this project to be $173,116. RECOMMENDATION Purchasing recommends the Common Council award this bid to EGI Mechanical Inc. for $179,616.
