TO:
HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM:
David A. Webb, Public Works Director - 949-644-3311, [email protected] PREPARED BY:
Michael J. Sinacori, Assistant City Engineer - 949-644-3342, [email protected] TITLE:
Approval of Amendment No. Two to Professional Services Agreement with Corrpro Companies, Inc. for Cathodic Protection Program, Contract No. 9483-1 (24W11) ABSTRACT:
Many of the City’s water transmission main pipelines are mortar lined and cement coated steel pipes that must be protected from corrosion. Amendment No. Two to the Professional Services Agreement with Corrpro Companies, Inc. provides funding for detailed cathodic protection system design plans, specifications, and bid and construction phase inspection services for the waterline Cathodic Protection Program.
RECOMMENDATIONS:
a) Find this project exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15302(c), Class 2 (reconstruction of existing facility involving negligible or no expansion of capacity)] of the CEQA Guidelines, because this project has no potential to have a significant effect on the environment; and b) Approve Amendment No. Two to Professional Services Agreement with Corrpro Companies, Inc. (Contract No. 9483-1) for additional design services with an increased not-to-exceed amount of $138,755 for a total not-to-exceed amount of $247,610, and authorize the Mayor and City Clerk to execute the amendment.
DISCUSSION:
Corrpro Companies, Inc. is the consultant working on the waterline cathodic protection program. The cathodic protection program involves the installation of new sacrificial anodes near new and existing test stations along each water transmission main pipeline. Anodes are connected to the metal pipelines to prevent corrosion and extend the useful life of the pipelines.
The City of Newport Beach Department requested proposals from three firms to implement a cathodic protection program. The proposals were evaluated and Corrpro Companies, Inc. (Corrpro) was determined to be the most qualified consultant. Corrpro was retained to perform a 2024 survey of the existing cathodic protection test stations along nine water transmission main pipelines and to create a report identifying its findings. After the initial report, it was determined that the next step was additional testing at each cathodic protection test station and creation of a pre-design survey report. The additional work was performed under Amendment No. One for $49,000, for a total contract value of $108,855.Corrpro’s Cathodic Protection System Pre-Design Survey Report, produced in the fall of 2024, recommended upgrading the existing cathodic protection and corrosion monitoring systems with galvanic anode cathodic protection to mitigate corrosion, preserve the integrity, and extend the service life of the pipelines.
Staff recommends City Council approval of Amendment No. Two with Corrpro to provide detailed plans, specifications, bid and construction phase services so that the cathodic protection program can be constructed and implemented.
FISCAL IMPACT:
The adopted Capital Improvement Program budget includes sufficient funding for these additional services. Work will be expensed to the Water Capital Master Plan account in the Public Works Department, 70201931-980000-24W11. The consultant’s proposed not-to-exceed fee for this additional service is $138,755.
