1.4 Background

The City completed a SCADA installation for the Wastewater Treatment Plant (WWTP)

between 2006 and 2010. It is the City’s intent is to use that SCADA system as a technical base

for all future SCADA work in the City, to ensure uniformity across all City SCADA systems.

The future upgrades will be divided into two separate projects – Water System and Lift

Stations.

The proposed SCADA HMI architecture takes all three systems into account for the total future

goal. This Project is focused strictly on the Water SCADA System, however, the end goal

must be considered so that any work completed acts as a stepping stone to achieving that final

goal.

This RFQ/P provides the conceptual design requirements for the Water SCADA System

upgrade in conjunction with the City SCADA Standards, enclosed, which provide details at a

high level. It is the proposer’s responsibility to become fully familiar with the state of the

WWTP SCADA System. The selected proposer will be responsible for this the water system to

provide a fully functional SCADA system with a similar user experience. All details are

conceptual and it will be the responsibility of the selected proposer to verify that the equipment

as specified will fit in the enclosed described cabinets and to provide the City with detailed

panel drawings depicting the future configuration of the existing panels.

1.5 Water SCADA System Current State

Crescent City currently has a Citect Explorer based SCADA system dating back to 1999 for the

water distribution system that incorporates Modicon TSX PLCs for control. The City’s water

system is comprised of the Ranney Collector, the Chlorine Building, five (5) pump stations,

five (5) storage tanks, and four (4) pressure monitoring sites. The Ranney Collector is the

source of water for the entire city and parts of the County. This source has been plentiful and

presented no cause for concern regarding supply for present or future needs. This system

currently monitors and/or controls the following water system functions:

• Three pumps at the Ranney Collector, for station on/off control only, but no automated

routines;

• Chlorine residual and flow rate monitoring at the Chlorine Building;

• Elevation level of the water in the Elevated Tank;

• Water elevation level in the Washington Tank and associated pump station operation; and

• Water elevation level in the Amador Tank and associated pump station operation.

The current water distribution system network is a serial based network operating on the

Modbus Plus protocol and utilizes a combination of tone-telemetry over leased telephone lines

and 453 MHz licensed radio for communication from the central SCADA node located at the

6

corporation yard to remote water facilities. A Master PLC at the corporation yard controls all

communication with the remote facilities and it provides the data and command interface for

the SCADA HMI system. There is a corporate IT network at the Ranney Collector and the

Chlorine Building via a cable company media.

Refer to Appendix A for a Network Block Diagram of the existing system.

The following systems have no current connection to the central SCADA system: Wigley Tank

and Pump Station, Bertsch Oceanview Community Services Area Tank and Pump Station, and

the Church Tree Tank and Pump Station.

2.0 Proposed SCADA HMI Architecture

The proposed plan is to install all the Water System SCADA servers and communication equipment on

the second floor of the Crescent City Fire Hall located at 520 “I” Street. This should provide adequate

protection in the event of a tsunami since the building is above the flood level of past events. The

actual location of the Water SCADA System operator workstation is yet to be determined.

Communication will move from serial to ethernet I/P. The system will use segmented portions of the

existing City network to connect facilities. Those that do not have connection to the existing City

network will move to a “Leased Network” (cellular, telco, or cable) to the Fire Hall.

The following diagram shows the proposed core SCADA components:

The Water SCADA System servers will eventually become the core of the entire City Water

and Wastewater SCADA Systems. The existing WWTP SCADA System contains four (4)

7

stand-alone PC systems that are joined to a workgroup rather than a domain.

The City SCADA System will be implemented in the following phased approach:

• Phase 1 Water System

• Phase 2 Collection System (21 sites) added to the City SCADA system servers

• Phase 3 Migrate the WWTP System onto the City SCADA system servers

3.0 Proposed SCADA PLC Architecture

The following subsections will identify the proposed PLC architecture for each facility. The primary

intent is to fit the replacement PLC into the existing enclosure. It will be the selected proposer’s

responsibility to verify that this is indeed possible and to document what other modifications may be

needed to accomplish this task.

Note: These proposed configurations follow the PLC Hardware Requirements section of the Standards

Document at the time of its development.

The following table shows a summary of the existing PLC details for each Water System facility and

the proposed replacement:

enclosure. A 24 Vdc power supply will be needed to supply power to the pressure transmitter

for the analog input signal.

This solution will be installed at all the Pressure Monitoring sites:

• Parkway

• Mason Mall

• Cooper Street

• Pebble Beach Drive

3.11 Wigley Pump Station

Currently, this site has no communication to the existing SCADA system. Communication

capabilities to the Water SCADA System will need to be added.

The site does communicate with the Wigley Tank to get the tank level analog input via a

hardwired CMC modem. A pressure switch is also wired into the pump control circuit to

ensure that there is enough suction pressure to the pump. A separate enclosure to house the

new CompactLogix PLC will need to be designed and installed to interface with the existing

control panel to obtain the tank level and pump controls.

4.0 Process Control Narratives

The selected proposer will be responsible for the development and documentation of Process Control

Narratives (PCNs) for the system. This will be accomplished by working closely with the City to

determine what changes are required of the existing system operation and reverse engineering of the

existing Modicon TSX PLCs, including fault tolerance to the existing system.

The following is a preliminary list of some of the anticipated modifications to the existing system:

• Controllable devices will be given a preset time limit within which a normal remote operation

should have been completed. If the operation is not completed within the preset time limit, an

alarm will be generated and shown on the HMI and logged. If the operation failure is due to a

control system or communication malfunction, different messages will be shown and logged.

For a successful operation, confirmation messages will be shown on the HMI and logged.

• After selecting the appropriate menu action, the control request and the point selection will be

automatically reset such that additional supervisory control commands can be selected.

• A control point selection will be cancelled when:

o Another new point has been selected after the point selection

o The desired action on the selected point has been taken

o An invalid operator action is performed after point selection. The system shall display a

text message informing the operator of the invalid action.

o If a control point has been selected, action such as paging or new display call up shall

be allowed and is considered an implied cancel so no operator error message is

generated.

o A predefined amount of time has elapsed without any operator action.

• All Control Pop Up displays must be movable on the graphic display by simply selecting the

pop up via the pointing device and dragging it.

• Placing and removing IN SERVICE or OUT OF SERVICE flags will be a matter of simply

selecting the choice in the popup display and clicking the mouse.

• The OUT OF SERVICE feature will be provided on an individual device basis. When an

individual device is OUT OF SERVICE, it must not be processed by the data acquisition

function for the alarm system. This may or may not be coupled with the operator overriding a

value. Upon IN SERVICE, the data processing for alarming functionality will resume for the

individual device.

• All appropriate displays will show the value of the device when it was out of service.

• All OUT OF SERVICE points will be displayed on a summary display for monitoring and

printing.

• User should be able to determine that a piece of equipment is out of service by a graphical

indication.

the firms that meet the mandatory requirements and whose Proposals are responsive, the firms will

receive a preliminary score/ranking.

The City reserves the right to request additional information which, in the City’s opinion, is necessary

to evaluate whether a Proposer’s qualifications, experience, number of qualified employees, business

organization, and financial resources are adequate to perform the Services required for the Project.

The City will require highest 3 to 5 ranked firms, including key personnel, to make an oral presentation

to and answer questions from members of the selection committee. The proposed format for the

interview will include an opportunity for a short introduction and statement of qualifications of the firm

and key personnel, a discussion of the firm’s Project approach and implementation, a short question-

and-answer period, and any closing remarks.

Upon completion of the interviews and verification of references, the highest ranked proposer, based on

the interviews, will be invited to open negotiations for a Professional Services Contract. The City will

attempt to negotiate a mutually agreeable professional services agreement with the most qualified firm.

Fee and hourly rate information will be used for discussion purposes and will not be disclosed to other

Proposers.

In the event the City is unable to negotiate a satisfactory contract with the firm considered most qualified,

23

negotiations with that firm shall be formally terminated. The City shall then undertake negotiations with

the second most qualified firm. Failing to reach accord with the second most qualified firm, the City

shall terminate negotiations and commence negotiations with the third most qualified firm. Should the

City be unable to negotiate a satisfactory contract with any of the top three qualified firms, the City shall

select additional firms in order of their competence and qualifications and continue negotiations, or take

whatever other actions are deemed to be in the best interest of the City. Upon reaching a satisfactory

agreement, a recommendation will be made to the City Council for award of the contract.

After award of the contract by the City Council, the City will tender the executed Agreement to the

Contractor.

The selected firm shall commence services upon receipt of City’s written Notice to Proceed.

The City reserves the right to select the firm, which in the City’s sole judgment, best meets the needs of

the City. The City reserves the right to add or remove any portion of the Project.
