TO: WILLIAM A. HUSTON, CITY MANAGER
FROM: PUBLIC WORKS DEPARTMENT/WATER SERVICES DIVISION
AWARD OF BID FOR SUPERVISORY CONTROL AND DATA ACQUISITION
SUBJECT: (SCADA) SYSTEM FOR THE WATER SERVICE STORAGE AND DISTRIBUTION
NETWORK
RECOMMENDATIONS:
That the Tustin City Council authorize the award of bid for Water
Services Supervisory Control and Data Acquisition (SCADA) System in
the amount of $299,950 to the low bidder, Phoenix Controls, Inc.,
and authorize a supplemental 1992-93 budget appropriation in the
amount of $160,300 from the unappropriated reserves of the Water
Service Capital Projects Fund.
BACKGROUND:
In August 1992, the City Council authorized the solicitation of
bids for the Water Services (SCADA) System. The City's existing
equipment, which monitors system facilities (i.e., wells,
reservoirs, booster pumps, etc.) is outdated and unreliable and
repair to the existing system is difficult and expensive. The
proposed SCADA System will provide state of the art monitoring and
control of the water system facilities. It will have the capacity
to store and printout data, which would provide information for
water management and daily operations. The automation of this
equipment will reduce the need of man-hours required to
monitor/check facilities after normal working hours.
DISCUSSION:
Bids were received on September 8, 1992, for the proposed SCADA
System and are tabulated as follows:
- Phoenix Controls, Inc., Phoenix, AR 00.00000 $299,950
- Leeds and Northrup, Northwells, PA.......... $430,959
- Tesco Controls, Inc., Sacramento, CA ....... $499,467
The low bid of $299,950 is 8.3% below the Engineer's estimate of
$327,000. Staff has reviewed this bid with the low bidder, Phoenix
Controls, Inc., and checked references on their past contracts and
is satisfied that they can complete the project in an acceptable
manner. This project is a specialty type service and there is not
a large number of potential bidders for this type of work.
There is currently a $149,691 project balance available in the
Water Service Capital Projects Account No. 600064. This balance,
less the contract bid amount of $299,950, plus a $10,000
contingency amount results in a funding shortfall of $160,300, due
to an under estimated initial project budget request.

In order to proceed with this project, as a single phase project,
it is requested that the City Council authorize a supplemental
1992-93 budget appropriation in the amount of $160,300 from the
unappropriated reserves of the Water Service Capital Projects Fund.
This supplemental appropriation has been discussed with the Finance
Department and has been found to be acceptable from a cash flow
perspective.
