AGENDA ITEM: Resolution Awarding Contract to Tesco Controls -City of Livingston Well #13 and Well #17 – SCADA System Integration
MEETING DATE: May 17, 2016
PREPARED BY: Alfonso Manrique, Alternate City Engineer
REVIEWED BY: Odi Ortiz, Interim City Manager
Staff recommends that the Council awards a contract to Tesco Controls for the integration of Well #13 and Well #17 into the City’s SCADA to provide full remote control and operation of the treatment systems.
The City of Livingston’s Well #13 has a new Arsenic Removal Treatment System and Well #17 has a similar system under construction. The Arsenic Removal Treatment Systems were supplied by Loprest Water Treatment Company.
The Controls for the arsenic removal treatment systems are able to send alarms through the existing Tesco PLC. However, the systems do not communicate the nature of the alarms and do not allow for remote control of the systems.
The Well #13 Arsenic Removal Treatment system was recently completed and the Well #17 system will be completed in the near future. City staff would like to have remote access to better monitor the treatment systems and to minimize the trips to the well sites to reset alarms.
The construction costs for Well #13 were originally budgeted to be $1,548,836. To date the City has spent approximately $1,260,000.
Funding for Well #13 is being provided by the SWRCB through the DWSRF at a rate of 1.6 percent for 20 years.
Well #17 is funded through a CDBG grant and the City’s water fund.
The proposed improvements to the wells included in Tesco’s proposal will integrate the Loprest PLC Screens into the City’s SCADA System. The improvements require new programming of the existing Tesco PLC. The Tesco PLC uses proprietary programming and can only be accessed by Tesco programmers. The integration of the system at the wells must be done by Tesco.
Chapter 11, Section 1-11-6 of the City’s Municipal Code provides that formal bidding may be waived if the products or services requested are available from only one source.
Tesco’s proposal to integrate Well #13 is $45,000.00. This item will be paid using the DWSRF Loan. It is anticipated that the project will be more than $200,000.00 under budget.
Tesco’s proposal to integrate Well #17 is $4,155.00. This item will be paid using City water funds.
