6. Software:
a. Software will be included to automatically and gradually ramp up
irrigation system pressure to the desired operating pressure (i.e.,
1 PSI every 3 seconds) without overshooting design pressure.
This feature operates whenever pressure drops below set point
pressure. This ramp up time is fully adjustable by the operator.
This control feature is based on an increase in pressure over a
pre-defined time period. The acceleration control on the VFD is
NOT an acceptable means of adjusting pressure ramp up speed.
b. Software will be included for optionally maintaining a lower
irrigation system pressure when not irrigating. Reduced pressure
values will be shown in the technical data sheet. Controls will
cycle the PM pump at these reduced pressures during non-
irrigation times and pressure will gradually increase to design
pressure when the irrigation periods begin.
c. Neither flow meter nor VFD output frequency shall be used for
shutting down last VFD driven pump. Controls and software shall
incorporate a method to eliminate excessive cycling of VFD pump
at very low flow conditions, yet not run the pump excessively at no
flow conditions.
d. Provide automatic alternation of VFD driven pumps accomplished
by incorporating dual mechanically and electrically interlocked
contactors allowing alternation of the VFD between pumps.
e. Real time clock calendar allows PLC to internally provide all date
and time functions used above.
f. Two separately adjustable PID control loops for both low flow and
high flow pressure stability.
g. Provide system that allows user to field select either two modes of
VFD operation. Auto switch VFD option allows VFD to
sequentially start each pump. The standard mode of operation
starts the first main pump on the VFD and the remaining pump
starts across the line as required.
h. Shutoff algorithm for fixed speed pumps to minimize pump cycling
while also remaining responsive to sudden flow reductions.
Minimum run timers alone for minimizing fixed speed pump cycling
is not acceptable. Discharging through relief valve during pump
transitions is not acceptable.
i. Full manual operation capability with panel face mounted speed
potentiometer for manually adjusting VFD speed.
j. System can be immediately and directly switched from manual to
automatic mode of operation. This allows for manual
pressurization and immediate switching capability to automatic.
k. Light test sequence. Pressing the reset button for 5 seconds
illuminates all lights.
l. Rate of pressure change algorithm to rapidly determine if there is
an irrigation demand and immediately cycle on the VFD pump, in
lieu of waiting for pressure to drop to a predetermined start
pressure.
m. All pump station shutdowns shall be of the controlled type which
sequentially phase pumps off at user selectable internals to
reduce water hammer within the irrigation system.
7. Operator Interface Device (OID):
a. The pump station shall include a NEMA 4, 40 character LED
display and keypad mounted on the control panel door. This
device will allow the operator to view and selectively modify all
registers in the PLC. The unit shall store its messages in non-
volatile memory. The operator interface device shall incorporate
password protection for protecting data integrity. The device will
allow for display and modification of all timers, set points, lockout
times, etc. The device shall communicate with the PLC through
the programming port, and shall include an RS232
communications port allowing a printer to be attached for real time
station status logging.
b. The OID shall be an information system only and not required for
pump station operation. No switches, reset buttons, general alarm
light, run lights or speed potentiometers are included within this
unit. This pump station will be fully functional in the event the OID
unit should fail.
c. In addition to normal data entry keys, the device shall include a
minimum of the following function keys labeled:
(1) Event. Displays one of three data logging functions.
(a) Operator can scroll through the historical pump
station flows and pressures for up to the last 7
days. The operator can change sampling time
periods (from 1 to 60 minutes). Averages are taken
over the sample period and the average recorded
with time stamp.
(b) The last 128 sequential pump station events with
time of occurrence. Events shall include but not be
limited to: all alarms, starting of individual pumps,
stopping of individual pumps and changing of
selector switches.
(c) Station flow and pressure are shown every second
for the previous 60 seconds and every minute for
the previous 30 minutes. If a shutdown occurs, the
flow and pressure tables are locked in so that the
operator may view how the pump station was
performing immediately before the shutdown
occurred.
(2) Status. Will display the current operating status. When
the station is running, the display will show the setpoint
pressure, actual pressure, flow, and pump rpm.
(3) Alarm Info. It will display detailed information on the
alarm, time of occurrence, pumps operating at time of
alarm and how to correct the alarm condition.
(4) Daily Log. It will display the following: Last time of log
reset, individual pump run times, run times since last reset,
pump starts, pump starts since last reset, total flow, total
flow since last reset, highest flow rate with time of
occurrence, alarm conditions, and times since last reset.
(5) Scroll Key. Used to scroll up and down through data.
8. Operation:
a. During non-irrigation times, the pressure maintenance pump (PM)
will cycle on and off as required to maintain irrigation system
pressure. The cycling pressures can be user selected and can be
set substantially below normal set point pressure, if desired. If the
PM pump cannot maintain the desired pressure, then the VFD will
start the first pump and will gradually ramp the pressure up to
desired irrigation pressure.
b. The pump speed will be modulated to hold a constant discharge
pressure regardless of flow. As the flow rate increases and the
VFD pump can no longer maintain pressure while at maximum
speed, the next sequential pump will be started and the VFD
driven pump will accordingly reduce its speed and modulate.
c. An algorithm shall be include for accurately reducing the VFD
pump speed as the next sequential pump is started so that no
pressure surges are generated during the transition (even with
across the line starting). If the user prefers to switch the VFD from
pump to pump for sequential starting, he can select this option
with the OID.
d. As the flow continues to increase, pumps will sequentially be
started until all pumps are operating. As the flow begins to
decrease, pumps will be sequentially turned off until only a single
VFD driven pump is operating. When a no flow condition occurs,
the VFD pump shall be turned off.
E. Skid Wiring:
1. All wiring from control panels to motors shall be in liquid-tight conduit with
copper conductors rated not less than 600 volts AC and of proper size to
carry the full load amperage of the motors without exceeding 70%
capacity of the conductor. A grounding cable shall be included in the
liquid- tight conduit. There shall be no splices between the motor starters
and the motor connection boxes.
2. Wiring to flow sensors and pressure transducer shall be multi-conductor
shielded cable suitable for Class ll low voltage controls.

potentiometer for manually adjusting VFD speed.
j. System can be immediately and directly switched from manual to
automatic mode of operation. This allows for manual
pressurization and immediate switching capability to automatic.
k. Light test sequence. Pressing the reset button for 5 seconds
illuminates all lights.
l. Rate of pressure change algorithm to rapidly determine if there is
an irrigation demand and immediately cycle on the VFD pump, in
lieu of waiting for pressure to drop to a predetermined start
pressure.
m. All pump station shutdowns shall be of the controlled type which
sequentially phase pumps off at user selectable internals to
reduce water hammer within the irrigation system.
7. Operator Interface Device (OID):
a. The pump station shall include a NEMA 4, 40 character LED
display and keypad mounted on the control panel door. This
device will allow the operator to view and selectively modify all
registers in the PLC. The unit shall store its messages in non-
volatile memory. The operator interface device shall incorporate
password protection for protecting data integrity. The device will
allow for display and modification of all timers, set points, lockout
times, etc. The device shall communicate with the PLC through
the programming port, and shall include an RS232
communications port allowing a printer to be attached for real time
station status logging.
b. The OID shall be an information system only and not required for
pump station operation. No switches, reset buttons, general alarm
light, run lights or speed potentiometers are included within this
unit. This pump station will be fully functional in the event the OID
unit should fail.
c. In addition to normal data entry keys, the device shall include a
minimum of the following function keys labeled:
(1) Event. Displays one of three data logging functions.
(a) Operator can scroll through the historical pump
station flows and pressures for up to the last 7
days. The operator can change sampling time
periods (from 1 to 60 minutes). Averages are taken
over the sample period and the average recorded
with time stamp.
(b) The last 128 sequential pump station events with
time of occurrence. Events shall include but not be
limited to: all alarms, starting of individual pumps,
stopping of individual pumps and changing of
selector switches.
(c) Station flow and pressure are shown every second
for the previous 60 seconds and every minute for
the previous 30 minutes. If a shutdown occurs, the
flow and pressure tables are locked in so that the
operator may view how the pump station was
performing immediately before the shutdown
occurred.
(2) Status. Will display the current operating status. When
the station is running, the display will show the setpoint
pressure, actual pressure, flow, and pump rpm.
(3) Alarm Info. It will display detailed information on the
alarm, time of occurrence, pumps operating at time of
alarm and how to correct the alarm condition.
(4) Daily Log. It will display the following: Last time of log
reset, individual pump run times, run times since last reset,
pump starts, pump starts since last reset, total flow, total
flow since last reset, highest flow rate with time of
occurrence, alarm conditions, and times since last reset.
(5) Scroll Key. Used to scroll up and down through data.
8. Operation:
a. During non-irrigation times, the pressure maintenance pump (PM)
will cycle on and off as required to maintain irrigation system
pressure. The cycling pressures can be user selected and can be
set substantially below normal set point pressure, if desired. If the
PM pump cannot maintain the desired pressure, then the VFD will
start the first pump and will gradually ramp the pressure up to
desired irrigation pressure.
b. The pump speed will be modulated to hold a constant discharge
pressure regardless of flow. As the flow rate increases and the
VFD pump can no longer maintain pressure while at maximum
speed, the next sequential pump will be started and the VFD
driven pump will accordingly reduce its speed and modulate.
c. An algorithm shall be include for accurately reducing the VFD
pump speed as the next sequential pump is started so that no
pressure surges are generated during the transition (even with
across the line starting). If the user prefers to switch the VFD from
pump to pump for sequential starting, he can select this option
with the OID.
d. As the flow continues to increase, pumps will sequentially be
started until all pumps are operating. As the flow begins to
decrease, pumps will be sequentially turned off until only a single
VFD driven pump is operating. When a no flow condition occurs,
the VFD pump shall be turned off.
E. Skid Wiring:
1. All wiring from control panels to motors shall be in liquid-tight conduit with
copper conductors rated not less than 600 volts AC and of proper size to
carry the full load amperage of the motors without exceeding 70%

EXHIBIT B
INSURANCE REQUIREMENTS
1. The Service Provider will provide, from insurance companies acceptable to the City, the
insurance coverage designated hereinafter and pay all costs. Before commencing work under this
bid, the Service Provider shall furnish the City with certificates of insurance showing the type,
amount, class of operations covered, effective dates and date of expiration of policies, and
containing substantially the following statement:
"The insurance evidenced by this Certificate will not be cancelled or materially altered,
except after ten (10) days written notice has been received by the City of Fort Collins."
In case of the breach of any provision of the Insurance Requirements, the City, at its option, may
take out and maintain, at the expense of the Service Provider, such insurance as the City may
deem proper and may deduct the cost of such insurance from any monies which may be due or
become due the Service Provider under this Agreement. The City, its officers, agents and
employees shall be named as additional insureds on the Service Provider's general liability and
automobile liability insurance policies for any claims arising out of work performed under this
Agreement.
2. Insurance coverages shall be as follows:
A. Workers' Compensation & Employer's Liability. The Service Provider shall maintain
during the life of this Agreement for all of the Service Provider's employees engaged in work
performed under this agreement:
1. Workers' Compensation insurance with statutory limits as required by
Colorado law.
2. Employer's Liability insurance with limits of $100,000 per accident, $500,000
disease aggregate, and $100,000 disease each employee.
B. Commercial General & Vehicle Liability. The Service Provider shall maintain during
the life of this Agreement such commercial general liability and automobile liability insurance
as will provide coverage for damage claims of personal injury, including accidental death, as
well as for claims for property damage, which may arise directly or indirectly from the
performance of work under this Agreement. Coverage for property damage shall be on a
"broad form" basis. The amount of insurance for each coverage, Commercial General and
Vehicle, shall not be less than $500,000 combined single limits for bodily injury and property
damage.
In the event any work is performed by a subcontractor, the Service Provider shall be
responsible for any liability directly or indirectly arising out of the work performed under this
Agreement by a subcontractor, which liability is not covered by the subcontractor's
insurance.
