Re:
Harney County Jail – HVAC System Upgrades
Objective
The objective of this project is to replace, repair and maintain heating, ventilating
and cooling equipment in the Harney County Jail building, located in Burns,
Oregon. The project shall be structured as design/build. The successful contractor
will retain the services of professional engineers as necessary or if deemed
required by the Owner (Harney County).
Description
The jail facilities are heated using forced air supplied by small air handlers in
various zones throughout the facility. Heating water coils are installed in the
ducting directly downstream of the air handlers. An oil-fired boiler and pump
located on the premises provide the heating water supply and return flow through
the coils.
Fresh air intake grilles are located on outside walls and the balance between fresh
air and return air is controlled using dampers mounted within the return ducting
system. The dampers are presently not clearly marked and possibly need to be
replaced or repaired.
The existing system utilizes a rooftop-mounted evaporative (swamp) cooler to
provide nominal cooling in summer. Although the cooler provides some relief from
the heat, the additional humidity makes the building uncomfortable during the
warmer days.

Bidding Memorandum
Project Requirements
Bidding Specifications and Other Requirements
All work for this project shall be accomplished in accordance with the
accompanying specifications:
•
15200 – Basic Mechanical Requirements
•
15220 – HVAC System Requirements
In addition to these specifications, all work shall meet the requirements of local,
state and federal codes, including (but not limited to):
•
Oregon Mechanical Specialty Code – 2007
•
ASHRAE Standard 62-2001 Ventilation for Acceptable Indoor Air Quality
Potential Contractors shall be required to attend one (1) on-site pre-bid
meeting to inspect the existing facilities and systems and review the project
requirements with the Owner and Owner’s Representative.
Heating System
Heating water coils for the various air handlers are to be inspected, cleaned and
repaired (if necessary). An inspection of the hydronic system (heating water
supply and return) shall also be required to insure that all critical components
are present and operating. Based upon an initial inspection, it appears that the
system does not include an air separator in the heating water loop. If the air
separator is indeed missing, the installation of a new separator shall be
included within the scope of this project. Likewise, if insufficient drains and/or
air vents are not included in the piping system, required drains and vents shall
be installed as part of this project.
Cooling System
The existing evaporative cooler shall be removed and disposed of properly by
the successful Contractor. It shall be replaced by a rooftop unitary heat pump
system. The heat pump shall be used primarily for cooling in summer, but may
be called upon to provide supplemental heat in winter. For this reason, the heat
pump shall include electric resistance heating elements as required to meet the
demands of the Burns winter climate. Contractor shall supply a unit equivalent
to the Trane “Precedent” system. A brochure for the unit is attached to this
memo for reference purposes.
Ventilation System
Contractor shall be responsible for ensuring that existing dampers are
functioning properly. Damaged or otherwise non-functioning dampers shall be
replaced as required. Upon completion of the equipment installation and
2

repairs, the air system shall be balanced to ensure proper air flow (supply and
return) through the various zones serviced by the individual air handling
system. In order to ensure proper ventilation, it may be necessary to include
new ducting for return and/or outside air flow.
Project Bidding and Schedule
The objective is to complete the project before June 2014, sooner if possible.
Bidding requirements shall be as defined in the pre-bid meeting, scheduled for
Tuesday 17 December in the Harney County Courthouse located in Burns,
Oregon.
