gees, set backs from sewer lines, buildings, etc. it proved impossible to site enough additional
<br />wells to serve the Jail.
<br />The analysis conducted by RN&M also examined the feasibility of constructing a geothermal
<br />system for the Jail on the open space to the south andlar north. of the Historic Courthouse, but
<br />again, trees. and required setbacks eliminated this option from consideration.
<br />The system with the best life cycle cost of the other three examined was determined to be a
<br />four-pipe hydronic system to include a new boiler and chiller. A copy of the "range County Jail
<br />HVAC System ~Jpgrade--Life Cycle Cost Analysis" has been included as Attachment `A'
<br />~~ Chiller Replacement
<br />Due to its age and increasing unreliability, it is recommended that the existing chiller be
<br />replaced as soon_as possible..._~1~ithWthat_in mind,.__Pub.iic UI!'orks_.requested that. RN&M__develop
<br />specifications fog a recommended replacement cl~~ller that would be compatible with she overall
<br />HVAC system .replacement. Public Works and Purchasing then requested bids from four
<br />qualified HVAC contractors for the removal of the existing chiller and replacement with the
<br />modes recommended by RN&~l.
<br />Bids were received from four HVAC contractors, with Southern Piping, Inc. of Raleigh the low
<br />bidder at a cost of $45,929 for supply and installation of a Carrier 45 ton chiller. A summary of
<br />bids received for the supply and installation of the replacement chiller is presented as Table ~

<br />3~ proposals for Jail HVAC Systems Design ~ Existing Building. Gode Review
<br />Again, due to age and. condition; as well as the round~the-clock occupancy of the. Jail, Public
<br />Works recommends re lacement of the entire HVAC system. RN&M have provided a proposal
<br />p
<br />for performance of the HVAC system design work at a cost of .$54,000.
<br />The affected sections of the Jail for the HVAC system replacement were constructed in
<br />approximately 982. As such, building cede andlor accessibility def ciencies may be identif ed
<br />Burin replacement of the HVAC system. RN&M have. provided a proposal to, perform a "North
<br />9
<br />Carolina Building Cade chapter 34 Existing Building Code Review" to identify deficiencies that
<br />will be required to be remedied in order to proceed with the installation of a new HVAC system
<br />far the Jail. The cost for this review is $S,o00.
<br />r
<br />FINANCIAL II~pACT~ Adequate funds for this work are available in the HVAC Replacement
<br />capital account. Table 2 summarizes available funding in the HVAC capital account, a~ well as
<br />known and estimated cysts for each project element.
