body
Summary
The Municipal Utilities Department (MUD) operates and maintains 76 stormwater pump stations throughout the City that route stormwater runoff from the streets to local rivers, creeks, and sloughs. This project will improve the corrosion protection systems at twelve (12) stormwater pump stations at various locations.
At these pump stations, all metallic discharge pipes, corrugated metal wet wells and trash racks that are either submerged in water, or partially or fully buried below the ground were designed with Cathodic Protection (CP) system. A survey revealed that most CP systems are either depleted or non-functional.
As part of the 2018-23 Capital Improvement Program, this project aims to replace the existing CP systems at twelve (12) storm pump stations, restoring their functionality to continue protecting metallic components against corrosion.
On November 15, 2018, the City received one (1) bid for the Stormwater Pump Stations and Forcemains Cathodic Protection Repairs, Project No. M16010. If approved, this action will authorize the award of a Construction Contract in the amount of $672,095 to Farwest Corrosion Control Co. of Hayward, Calif.
DISCUSSION
Background
The City of Stockton Municipal Utilities Department (MUD) operates and maintains 76 stormwater pump stations throughout the City that route stormwater runoff from the streets to local rivers, creeks, and sloughs. These pump stations contain metallic structures, such as forcemains, corrugated metal wet wells and trash racks that are either submerged in water, or partially or fully buried in the ground. These metallic structures are safeguarded against corrosion by use of CP systems. The CP system is an electrochemical process that inhibits the natural corrosion process and extends the functional life of metallic systems and equipment.
The City contracted with JDH Corrosion Consultants, Inc. to perform a comprehensive assessment of existing CP systems at various City facilities. JDH completed the assessment and developed a report documenting the CP systems’ operational status and current level of protection. The assessment revealed that the CP systems at twelve (12) pump stations were either depleted or non-functional.
This project identified in 2018-23 Capital Improvement Program is to repair or replace the existing CP systems at the following stormwater pumps stations:
1. Charter Way Industrial Park Stormwater Pump Station
2. 8th Street and San Joaquin River Stormwater Pump Station
3. Stockton Airport (Pock Lane/Industrial Drive) Stormwater Pump Station
4. Western Pacific Industrial Park Stormwater Pump Station
5. Plymouth Road and 5 Mile Creek Stormwater Pump Station
6. Quail Lakes (Alexandria and 5-Mile Slough) Stormwater Pump Station
7. Royal Oaks Stormwater Pump Station
8. Fort Donelson and 14 Mile Slough Stormwater Pump Station
9. Grupe Business Park Stormwater Pump Station
10. West Lane and Calaveras River North Stormwater Pump Station
11. Thornton and Mosher Slough Stormwater Pump Station
12. Arch Road Industrial Park and Little John’s Creek Stormwater Pump Station
Present Situation
On October 15, 2018, the MUD advertised the project in The Stockton Record and posted to the City’s Bid Flash webpage. Additionally, a notice with a brief project description was sent to more than 150 contractors holding a Class “A” or “C-10” license.
A mandatory pre-bid meeting was held on October 25, 2018, with five (5) prospective bidders in attendance. On Thursday, November 15, 2018, one (1) sealed bid was officially received and publicly opened by the City Clerk with the following results:
Company Total Bid Amount
Farwest Corrosion Control Co., Hayward, CA $672,095
Engineer’s Estimate $676,800
Another bid from Exaro Technology, Inc. was received by the Office of the City Clerk one day after the bid opening date. Staff’s review determined that Exaro Technology, Inc, failed to send their bid to the correct address as stated in the bidding instruction. In consultation with City Attorney’s office, the bid was considered non-responsive and returned unopened to Exaro Technology, Inc.
The bid submitted by Farwest Corrosion Control Co. had the following minor irregularities:
• The missing title sheet of the Bid Forms;
• An arithmetic error for Bid Item No. 6 that resulted in a discrepancy amount of $260. The Contractor listed $3,250, but it should have been $3,510; and
• The acknowledgement form for design Clarification No. 1 was not included in the submitted bid packet.
Legal advice was sought from the City Attorney’s Office and determined that Farwest Corrosion Control Co. could correct the minor irregularities in their bid and resubmit to the City. It was deemed that this action does not materially change the bid or give Farwest Corrosion Control Co. an unfair advantage over the other bidder, as Farwest Corrosion Control Co. was the only official bid received.
The Farwest Corrosion Control Co. submitted all corrected, missing documents, and is now in full compliance with City’s bid requirements.
Farwest Corrosion Control Co. has the proper license and experience to perform the work. Based on the current industry pricing for the CP systems of such complexity, staff determined that the bid from Farwest Corrosion Control Co. is appropriate and recommends awarding the Construction Contract in the amount of $672,095.
The Local Employment Ordinance (Stockton Municipal Code section 3.68.095) applies to this Contract, but the Local Preference Ordinance (Stockton Municipal code section 3.68.090) does not, as the only bidder business address is outside the boundary of Stockton and San Joaquin County.
ENVIRONMENTAL CLEARANCE
The project is in conformance with the City’s General Plan, pursuant to California Government Code, Section 65402, and exempt from the requirements of California Environmental Quality Act (CEQA) as specified under Article 19, Section(s) 15302, Class 2 (c), of the CEQA Guidelines.
FINANCIAL SUMMARY
There are sufficient funds available in Account No. 447-7783-670 (Stormwater-CIP Storm Pump Station Modifications) to award the Contract in the amount of $672,095 to Farwest Corrosion Control Co. of Hayward, Calif., for the Stormwater Pump Stations and Forcemains Cathodic Protection Repairs, Project No. M16010.
There is no impact to the General Fund, or any other unrestricted fund, as a result of taking the recommended action.
