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.
