Justin Huntley
City of Fort Collins
Dear Justin:
Thank you for the opportunity to provide the City of Fort Collins with this proposal for building HVAC and
controls design work for the Edora Pool and Ice Rink HVAC and control systems. Iconergy has reviewed
the existing systems and developed a list of items that need to be designed and implemented to remedy
the indoor climate controls issues that currently exist. The following statement of work outlines tasks
that Iconergy will perform to complete the activities.
SCOPE OF WORK
Iconergy will provide complete MEP and structural design for the following items listed below. We will
also provide budgetary pricing information, with the assumption that the City of FC will directly procure
large HVAC equipment such as a cooling tower and natatorium air handling unit.
Cooling Tower
1. Demo and install a larger process cooling tower or cooling tower unit, such as the Baltimore
VTO-166-N or equivalent. The decision between a cooling tower with a remote sump or a
process tower is based on the structural analysis that the City of FC will provide for the
cooling tower location and an evaluation of the existing chillers as to whether or not they
can be modified for a remote condenser. Add a DDC condenser supply water temperature
sensor so that that BAS can control the cooling tower fan speed.
o If a cooling tower is installed, then the scope will be to disconnect the existing
cooling tower buffer tank from the condensing loop and install a new open system
tank / sump, allowing the two piping loops connection to the tank with an overflow
drain.
Install secondary condensing piping loop connecting the new cooling tower
to the tank. The existing condenser pumps can remain as new secondary
pumps. The existing condenser pumps will be evaluated for a VFD addition.
Connect the existing condensing piping loop into the new tank, install new
chiller primary pumps.
Chiller Plant Piping
1. Connect the existing Daikin chiller back into the system. Create chiller redundancy piping
option with 1 header for both chillers with a secondary split scenario between AHU-2 and
the rest of the chilled water loads with motorized three-way mixing valves. Install P/T
ports, and balancing valve at AHU-2 to ensure proper flow rate through the coil. Test and
balance the loop to provide the designed flow rate.
2. Insulate all chilled water pipes in the mechanical room.

AHU-2 Scope
1. Modify the AHU-2 dehumidification program in the BAS to control based on outside and
return air enthalpy for mixed air damper control. (C of FC will implement this item)
2. AHU-2 condensate pan does not drain properly because the drain pipe is on the suction
side of the fan and the p-trap is too short. To fix this, either install a condensate pump
outside the AHU on the condensate drain pipe or demo concrete at the condensate trap to
allow for a deeper trap relative to the inlet fan static pressure in inches of water.
3. Test and balance the existing AHU-2 air side and water side to ensure the AHU-2 operates
per design.
4. Investigate AHU-2 minimum fresh air damper control and repair and program as required
to open to the damper during occupied times.
5. Re-connect existing motorized dampers on the transfer louver between the East and West
ice rink. (C of FC will implement this item)
Heating System and Solar System
1. Isolate and drain 12 solar panels, or remove them from the roof. This 1 full row of panels.
(C of FC will implement this item)
2. Install buffer tank(s) into the heating hot water system to provide for 12 minutes of
buffering capacity. Re-purpose the chilled water remote sump tank for this purpose. Refer
to recent design documents provided by the City of FC.
AHU-1 Scope, Natatorium
1. AHU-1 replacement design, add energy recovery, dehumidification. Package unit, stainless
steel, pool pre-heat condenser energy recovery to pool water. Annexair or equivalent. To
be located in existing AHU-1 air handling room.
Building Automation System Scope
(C of FC will implement these items, so these are excluded from the design)
1. Program an alarm in the BAS for the ice rink dehumidification unit DHU-1 to alarm if the
energy recovery wheel is enabled and the entering air temperature and the existing air
temperature are within 10°F after being enabled for 10 minutes.
2. Review and calibrate temperature and humidity sensors to make sure the readings in the
BAS system are correct.
3. Once the AHU-2 dehumidification system if operating properly, re-locate the DHU-1
humidity sensor from the West rink to the East ice rink.
4. Modify the AHU-2 dehumidification program in the BAS to control based on outside and
return air enthalpy for mixed air damper control.
5. Install a new dedicated humidistat for AHU-2 in the return ductwork and interlock with BAS.
6. Evaluate installing a hot gas pressure sensor on the processing tower or temperature
sensor on condensing water, interlock sensors with tower fans and pumps VFDs (for
processing tower option) or secondary cooling tower VFDs to control and monitor the
tower’s capacity and performance.

General Activities
Meetings
1) Attend weekly webinar meetings until the design is completed.
2) Include site visits as needed to support the design
Design Submittals
1) Prepare submittals for the following milestones:
a) Preliminary review set at 50% of design (design development)
2) Construction documents
a) Construction documents will include two (2) sets of original sealed drawings for
submittals to code authority having jurisdiction and up to two (2) additional sets.
Bidding Phase Services
1) Assist by reviewing subcontractor bids
2) Review of substitution requests
Drawings
1) All drawings will be prepared in AutoCAD 2021 version.
2) All submitted plans to the client/contractor will be in PDF version.
Construction Administration
Note: CA for the Natatorium AHU-1 is being presented as an add-alternate in the fee section
1) Construction administration will include submittals review, RFI responses, (2) construction field
observations.
2) Record drawing preparation (as-builts)
3) Attend OEC meetings weekly (2/3 of which are remotely) during construction (assumed 8 weeks
& meetings)
Mechanical Engineering and Design
1) Field verify all available existing conditions, existing electrical and HVAC equipment, and duct
routing. If ceiling tiles will be removed prior to the construction, further duct routing and
drawings adjustments will be provided.
2) Perform calculations for required heating, cooling, humidification, and dehumidification loads
and requirements. The calculations will be performed based on the Design criteria described
below.

4) Provide building automation system sequence of operation and control diagrams.
5) Provide Master Specifications for the project.
Plumbing Engineering and Design
1) Field verify all available existing conditions, and locations of sanitary sewer systems.
2) Specify condensate drain routing and connection to the existing sewer line.
Electrical Engineering and Design
1) The Iconergy team will investigate existing electrical systems, and design new electrical wiring
and breakers as required for the new HVAC solution. Iconergy is sub-contracting the electrical
design to Corey Electrical Engineering.
Architectural Design
1) N/A. We do not anticipate having any architectural work associated with this work. Its possible
that the AHU-1 replacement solution will need to include architectural design work, and if so,
we will need to discuss adding this scope with the city of Fort Collins at that time.
Structural Design
1) JVA / Iconergy will evaluate the structural implications associated with the cooling tower
solution and the natatorium AHU system and include structural design as necessary in our
design solution. The budget presented for structural design in this proposal is just for an initial
review of the existing situation, and the deliverable is a letter of findings and
recommendations. If structural strengthening is required, the design fees are anticipated to be
an additional amount between $3500 and $7500.
