TO: Board of Commissioners DATE: July 23, 2008
FROM: Toby Taylor, Buildings & Grounds Coordinator
SUBJECT: Air Conditioning Units in Centennial, B0800113
We have two Air Conditioning Units located on the 3`d floor in a room behind Accounting. These
units supply the cooling air for the main hub of the ACS computer equipment which keeps the
county running. Loss of cooling air can cause this expensive equipment to overheat and fail.
One AC unit quit working some years ago and was abandoned in place due to repair/replacement
costs being so high. This caused us to lose any back up cooling capability. Recently,the second unit
has been subject to unpredictable shutdowns. Each time it shuts down we don't know if we'll be
able to get it started again. Not the situation we want to be in with such a critical communication
hub. These units appear to be original equipment when the Centennial Center was built. These AC
systems are so old that parts aren't commercially available. We explored the potential to upgrade the
existing AC units with three local vendors. After seeing the units, no one would provide us with a
price because they are so archaic.
Therefore, we conducted a bid to have companies come in and give us their solution and price to
provide the 20 tons of cooling capacity we needed for the space. We also stipulated that we wanted
redundancy. This means that there shouldn't be a single point of failure which would cause us to
lose all cooling in this critical room. The simplest way to achieve redundancy is to have a minimum
of two AC units. That left the bidder open to select any number of options to provide us the cooling
air we needed. McCreery and Sun chose a system which uses six smaller units to provide the
necessary 20 ton cooling capacity. Frontier Mechanical chose to go with a very robust larger brine
type system in two separate units to achieve the 20 ton cooling. The other vendor(s)provided no bid.
Buildings and Grounds recommends the low bid from McCreery and Sun of Colorado, Inc be
awarded and the second low bid from Frontier Mechnical, Inc. be rejected.
If you have any questions, please contact me at extension 2023.

Toby, Monica would like a little more information on this approval letter to state that we had requested 2 units and the low
vendor is installing 6 units. The commissioners are going to ask why we are going to install 6 units and will that meet are
needs. So we need to be a little bit more technical for the commissioners. They were already asking questions today.
Thanks
