SRN&M}; 2} Consider authorizing a contract with Southern Piping , Incorporated of Raleigh for replacement of the approximately ~5 year old Jai! chiller and; 3~ Consider authorizing a contract for professional services .with RN&M for the design of a replacement heating, ventilation and air conditioning ~HVAC~ system for the arange County Jai! pre-199? sectors} as recommended in the Apri! ADO? system analysis, including preparation of bid. documents and construction management and far performance of an Existing Building Code Review. BACKGROUND: The HVAC system serving the pre-199? sections of the Jail is approximately 25 dears old, and as such is~ beaming increasingly unreliable far meeting the on-going demands of this 24 hours per day, 355 day per year facility. In additive, due to growth in the number of occupants staff and inmates} and modern standards for ventilation, the overall HVAC system is in need of replacement. ~ ~ grange County Jail HVAC System Replacement and Upgrades At its August ~Z, 2496 meeting, the Board approved retaining the services of RN&M tv identify current heatin and coolin loads forthe Jai! and to identify an apprapriateenergy-efficient g g replacement HVAC system, including improvements needed to bring the system to current standards for air flawlventilation, at a cost of $G,SaD. An additional $1,24Q was also approved at this time for design work to address air quality issues at the Court Street Annex building. This analysis was completed by RN&M in April Za? and determined that geothermal heat um s were nvtfeasible far serving the Jail. Initial consideration was given to adding the Jail to p p the gev-thermal system tv be constructed for the new Justice Facility, but due to locations of gees, set backs from sewer lines, buildings, etc. it proved impossible to site enough additional wells to serve the Jail. The analysis conducted by RN&M also examined the feasibility of constructing a geothermal system for the Jail on the open space to the south andlar north. of the Historic Courthouse, but again, trees. and required setbacks eliminated this option from consideration. The system with the best life cycle cost of the other three examined was determined to be a four-pipe hydronic system to include a new boiler and chiller. A copy of the "range County Jail HVAC System ~Jpgrade--Life Cycle Cost Analysis" has been included as Attachment `A' ~~ Chiller Replacement Due to its age and increasing unreliability, it is recommended that the existing chiller be replaced as soon_as possible..._~1~ithWthat_in mind,.__Pub.iic UI!'orks_.requested that. RN&M__develop specifications fog a recommended replacement cl~~ller that would be compatible with she overall HVAC system .replacement. Public Works and Purchasing then requested bids from four qualified HVAC contractors for the removal of the existing chiller and replacement with the modes recommended by RN&~l. Bids were received from four HVAC contractors, with Southern Piping, Inc. of Raleigh the low bidder at a cost of $45,929 for supply and installation of a Carrier 45 ton chiller.

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