Mechanical Systems

The existing range air handler shall be removed from the mechanical room and replaced with a
roof top type gas fired variable air volume (VAV) unit with packaged DX cooling on the roof of the
range with side discharge ductwork. The ductwork shall be routed to the end of the building and
brought in either thru the sidewall or down through the last plank of the roof depending on the
structural requirements. The interior ductwork shall be modified as required to convert the
pistol range to a properly operating tactical range.

Any return and supply ductwork to be reused shall be thoroughly cleaned to remove dirt and
debris before restart of the system. Any new ductwork shall be made of galvanized steel and
constructed in accordance with the recommendations of the ASHRAE Guide and SMACNA Guide
(Current Edition). Any flexible ductwork shall be in lengths no greater than 5’-0” and shall not
pass through any fire rated assemblies. Flexible ductwork shall only be allowed in concealed
locations.

The existing R-22 water source heat pumps located in the 1977 portion of the building shall be
removed and replaced with new Variable Refrigerant Flow (VRF) fan coils served by an exterior
air source heat pump with heat recovery (Similar to the Trane Aurora). The new units shall match
the existing unit’s capacity and the existing ductwork shall be modified as required to install the
new heat pump.

The existing dedicated outdoor air handler located in the 1977 mechanical room shall be
removed and replaced with a new outdoor air handler heat pump with gas fired preheat. The
unit shall include an energy recovery ventilator, and variable frequency drives. The unit shall be

installed onto the roof and shall be re-ducted to the existing outdoor air ductwork and the
existing exhaust ductwork shall be rerouted from the existing exhaust fan to the ERV. The VRF
fan coils shall provide final tempering of the ventilation air and handle the latent loads.

The existing closed-circuit evaporative cooling tower (50-ton) located on the roof of the shooting
range/garage shall be removed including all associated pumps, piping, and valves. The water
source loop shall be removed with only the space heating distribution lines feeding fin tube and
hot water coils to remain.

The existing boiler plant in the 2000 addition shall remain and the circulation pumps shall be
replaced with self-sensing variable frequency drive (VFD) pumps. They shall be set to operate
based on delta-P to reduce building energy usage. The existing boiler plant in the 1977 portion
of the building shall be removed and the boiler returned to the owner for reutilization.

The VAV air handling units serving the 2000 addition shall be removed including their associated
condensing units located on the roof. A new rooftop Dedicated Outdoor Air System (DOAS) shall
be installed on the roof in a location to be determined. The DOAS shall be provided with an
Energy Wheel and an air source heat pump with gas fired preheat. The existing ductwork and
reheat coils shall be removed or reworked as possible to be fed from the new ducted VRF fan
coils. New distribution ductwork shall be provided to serve ventilation air to the return side of
the fan coils for final tempering and dehumidification. The building pressure sensor shall control
the exhaust air damper on the RTU to maintain a building pressure of +0.01” WC to minimize
infiltration of untreated exterior air.

The existing ventilation fan for the garage shall be replaced with new and provided with a control
via CO/NOx control panel and sensors. The exhaust fan shall run at 0.05 CFM/SF during occupied
periods. Upon activation of the CO/NOx sensors, the fans shall ramp up to 0.75 CFM/SF until the
CO/NOx levels are reduced to normal levels. The garage shall be provided with ductless VRF wall
mounted fan coils to provide cooling during the summer and the heat pump shall be located on
the roof of the garage. The existing hydronic unit heaters shall remain, and new thermostats
and control valves shall be provided. The new makeup air unit shall be provided with a face and
bypass damper and served off the existing hydronic hot water system.

Existing hydronic fin tube radiation shall remain for reuse and all thermostats and automatic
control valves shall be replaced. Any existing cabinet unit heaters and unit heaters shall remain,
and any existing control valves and thermostats removed and replaced.

A new DDC BMS shall be provided similar to a Niagara Version 4 system. The new system shall be
provided with a network gateway, remote monitoring, and trending capabilities. The system shall
be open source and allow for modification and extension by third parties. The system shall
control the occupancy schedule and all zone set points. Limited zone control of +/-2°F shall be
provided in the space with a 3-hour reset to default. The new DDC BMS shall integrate the
proposed VRF system controls.

Electrical Systems

The existing electrical service is 2000 ampere, 277/480V, three phase, four wire main service
that terminates in an (3) section Main Switchboard located in the basement. The switchboard is
a GE Spectra Series and appears to have available physical space for additional of any required
circuit breakers as part of the HVAC upgrade.

The service is fed from a utility pad mounted transformer located at the rear of the building.
Adjacent to the pad mounted transformer is exterior mounted electrical gear and a 250KW
diesel generator. The generator is rated at 376Amps @ 480V, 3P.

The data provide by Eversource notes the existing demand on the facility is approximately
242KW and an equivalent to 291Amps @ 480V, 3P.

Panelboards are installed throughout the facility in various mechanical and utility rooms with
step down transformers. These panelboards may be utilized for the HVAC renovation project
with further review if future space is available. The panels appear to be in good shape and
labeled with directory cards.

The existing addressable fire alarm system is manufactured by FCI (S3 Series). Additional
required equipment and/or Modifications may be supported by the existing Fire Alarm System if
deemed expandable by a licensed fire alarm installer.

not anticipated, but are necessary to close out the project. This money is available and was part of the
overall project budget through the owner’s contingency, but not included in the original construction
contract figure. The overall project and the bond authorization always conceived of a $3.6M project and
this project should come in under budget and on time.

Building Exterior Lights $15,000.00
Landscaping $25,000.00
Pressure Wash the Exterior $ 6,000.00

ON THE QUESTION

Mayor Donchess

Now is it Julie or Tim who is here on this?

Julie Chizmas

| am here Mayor.

Mayor Donchess

OK Julie Chizmas, please go ahead.
Ms. Chizmas

Hi, thank you so much for having us on your agenda tonight. | am here to discuss the contract of the Mill Yard
Dog Park feasibility study. | siton the Animal & Dog Park Advisory Committee, Alderwoman Klee also sits on
that Committee, who is here with us this evening. This study is a result of the efforts of that Committee to find
a location to construct and operate a downtown dog park. We have identified a lot, Lot 77-5 and just want to

know if this is feasible from an environmental point of view, an operations point of view, funding point of view.
So that’s why we are here this evening.

Mayor Donchess

Alderwoman Klee?
Alderman Klee

Thank you Mr. Mayor. | do want to add to this, it says it includes the cost of the private utility locator and Ms.
Chizmas if | am wrong on this, please feel free to correct me. But the reason for that was because there is a
large, | don’t want to call it a utility pole, but it is for one of the radio stations. And underneath the ground is a
gridwork of wiring. What this will do is it will tell us exactly where their wiring is so that if we do put up a fence,
we miss all of that. We don’t disconnect them, we don’t put anybody into harm’s way. It will also tell us how
far down that is so that if a dog were to dig, because this grid does go quite a distance out. So all Ms. Chizmas
has done all of her homework incredibly so, as usual, and it is amazing to find out all the different things. But
this is also very — a flood plain area — | think is what it is called. So we are going to check the feasibility as to
whether or not this would be able to be used all year round. Are there going to be certain limitations to it. And
we don’t want to hurt the environment because it does go along the Nashua River there and so on. So that’s
what this feasibility study will do, not just can we put it there and will everybody be happy, but whether or not
the ground can take it, what we would have to do in order to make it feasible or to be able to work and so on.
Do | have that correct, Ms. Chizmas?
