BACKGROUND
The treatment plant, including the Filter Plant, primarily uses Quantum Programmable Logic Controllers
(PLC) connected to Quantum 1/0 cards manufactured by Schneider Electric. PLC 1/0 cards are critical
for equipment and instrumentation communication for process control, monitoring, and data acquisition.
The first treatment plant PLC 1/0 card was installed in the mid-1980s. Today, the number of 1/0 cards in
use has grown to nearly 1,800.Approximately 1,100 of these 1/0 cards are outdated and replacement
units cannot be purchased from the manufacturer, and they are no longer supported by their service
department (software or hardware). Central San has maintained an inventory of spare 1/0 cards to replace
units as they fail or need to be reprogrammed and tested, but that spare supply has depleted in recent
years.
This Project is the first of a multiphase effort to replace PLCs with modern Schneider Electric equipment
at the treatment plant. The Project will address long-term reliability for the treatment plant PLC system by
replacing PLCs at the Recycled Water Filter Plant, salvaging the PLC 1/0 cards to restock the
replacement inventory, and starting the implementation to modern networking PLC systems and matching
the new systems that have been added the past several years. The Filter Plant is the first area to be
retrofitted because of its operational flexibility; the facility can generally support brief control system
outages. The effort at the Filter Plant will serve as a "pilot" to optimize the approach of all future 1/0
replacements involving critical plant processes and numerous other capital improvement projects.
On November 16, 2017, the Board authorized staff to enter into a design agreement with TJC and
Associates, Inc. (TJC)for this Project. On December 21, 2017, the Board authorized staff to enter into a
Sole-Source Purchasing contract not to exceed $250,000 to receive a discount on the PLC equipment.
The final purchase amount was approximately$170,000 and the equipment is on site awaiting installation
by the Project contractor.
The Project will perform work in the same locations as the Filter Plant and Clearwell Improvements, DP
7361, which is currently at the predesign stage. The project teams have coordinated closely to ensure that
no stranded assets are installed or upgraded for DP 7361 under this Project. The new control systems
components and As-Built documentation developed in the Project will be leveraged during the design of
the Filter Plant and Clearwell Improvements Project to reduce design cost.
TJC and staff prepared the plans and specifications for the Project. The Engineer's estimate for
construction was $775,000. This Project was advertised on September 20 and October 4, 2018. There
are two bid schedules included in the Project: 1)the base bid schedule, which determines the basis for
award; and 2) an additive bid schedule consisting of Bid Items 1 and 2, which are for panels at the
Recycled Water Clearwell and forebay equipment. Five (5) sealed bids were received and publicly
opened on October 18, 2018. The Engineering Department conducted a technical and commercial review
of the bids and determined that Con J Franke Electric, Inc. is the lowest responsive and responsible
bidder.A summary of bids received is shown in Attachment 2. Staff recommends to include Additive Bid
Items 1 and 2 to the contract, since the Clearwell and forebay will not be a stranded asset as confirmed by
the Filter Plant and Clearwell I mprovements Project. The total cost for Additive Bid Items 1 and 2 by Con
J Franke Electric, I nc. is $50,500. The costs provided by the other bidders for the sum of additive bid
items ranged from $37,500 to $167,188. The construction contract, including Additive Bid Items 1 and 2,
will be in an amount of$668,600.
Central San will administer the construction contract and will provide contract management, administration,
office engineering, administer submittals and schedules, and provide construction inspection. An
agreement revision will be issued to TJC for construction support services under this Project at a cost not
to exceed $80,000.

CEQA
Staff has concluded that this Project is exempt from the CEQA under Central San's CEQA Guidelines
Section 15301, since it involves minor alterations to existing public facilities involving no expansion of use,
and CEQA Guidelines Section 15302, since it involves replacement of existing public facilities at the
same location and with the same purpose. Approval of this project will establish the Board of Directors'
independent finding that this project is exempt from CEQA.
ALTERNATIVES/CONSIDERATIONS
Alternative 1 - The Board can elect to reject all bids. This is not recommended since the work is needed to
maintain a reliable and serviceable control system.
Alternative 2 - The Board can elect to reject all bids and postpone the construction to a future date. This is
not recommended since spare 1/0 cards are needed now, and Central San received several bids from
qualified contractors and a competitive bid price from the lowest bidder.
FINANCIAL IMPACTS
The total estimated project cost is $1,426,000, which includes planning, design, 1/0 cards pre-purchase,
construction contract, contingency, and construction management costs as shown in Attachment 3. The
Project is included in the Fiscal Year (FY) 2018-19 Capital I mprovement Budget on page 181 with a total
estimated project budget of $4,342,000. There is adequate funding for this phase of the Project through
FY 2018-19 and FY 2019-20.
COMMITTEE RECOMMENDATION
The Engineering and Operations Committee reviewed this subject at the November 5, 2018 meeting and
recommended approval of the Project.
RECOMMENDED BOARD ACTION
Staff recommends the following:
1. Find that the Project is exempt from CEQA;
2. Award a construction contract in the amount of $668,600 for the construction of the Plant Control
System 1/0 Replacement Project— Phase 1, Filter Plant, District Project 7339, to Con J Franke
Electric, Inc., the lowest responsive bidder; and
3. Authorize the General Manager to execute the Contract Documents subject to submittal
requirements and include up to a 15-percent contingency.
