body
Summary
The Municipal Utilities Department (MUD) performs ongoing inspection and maintenance of the City’s sanitary sewer collection system that includes monitoring levels of corrosive gas accumulation, groundwater infiltration, and signs of age and disrepair. The MUD identified 29 sewer maintenance holes throughout the City that are severely deteriorated due to either high corrosive gas levels or high groundwater infiltration levels. The 2017-18 Sanitary Sewer Maintenance Hole Rehabilitation project addresses this deterioration by repairing and sealing the interior surface of the 29 sewer maintenance holes.
On August 2, 2018, the City received one bid for this project. Staff recommends award of the Construction Contract to SoCal Pacific Construction Corporation dba National Coating and Lining Company in the amount of $216,228. Staff also recommends that Council adopt a resolution approving the Notice of Exemption No. CE023-18 under the California Environmental Quality Act (CEQA), and approving the plans and specifications for the project. Construction is anticipated to be completed by the summer of 2019.
DISCUSSION
Background
The MUD performs ongoing inspection and maintenance of the City’s sanitary sewer collection system, with an emphasis on the larger diameter lines. The large diameter pipe inspection program consists of monitoring levels of corrosive hydrogen sulfide gas, groundwater infiltration, and signs of age and disrepair. Trunk lines, and the associated maintenance holes, with patterns of high corrosive gas levels are the highest priority for rehabilitation. The MUD’s inspection and maintenance program also includes visual inspection of maintenance holes to identify brick and mortar cracking that can lead to accelerated groundwater infiltration and rapid deterioration.
The MUD identified 29 maintenance holes that are severely deteriorated and are high priority for rehabilitation (Attachment A - Vicinity Map). The priority locations are part of the large diameter sanitary sewer system located along March Lane, Ryde Avenue, Los Angeles Avenue, and Turnpike Road situated within high groundwater table areas and exhibit significant infiltration levels.
The 2017-18 Sanitary Sewer Maintenance Hole Rehabilitation project is designed to eliminate infiltration, repair voids, restore structural integrity, and provide corrosion protection to the 29 maintenance holes identified for repair by the MUD’s inspection program. Rehabilitation of the 29 maintenance holes includes removing corroded or dilapidated material, performing necessary preparatory repairs, and applying monolithic epoxy coating to the wall surfaces of the existing maintenance holes. This method allows the rehabilitation to be done with minimal excavation and impact, and is anticipated to extend the maintenance hole service life a minimum of 25 years.
The work is highly specialized as it requires the use of specifically designed spray pump equipment to apply a bio-degradable concrete cleaner, followed by a high-pressure water or sand blasting process. All personnel handling and installing the epoxy coating material must be certified by the manufacturer with at least three years of experience and comply with all confined space entry requirements.
Public Works’ staff completed the preparation of specifications for this project, and the project was advertised for bids on July 5, 2018.
On July 26, 2016, Council adopted a Community Workforce and Training Agreement (CWTA). The CWTA became effective August 25, 2016, and applies to all Public Works projects over $1 million that are bid after that date. The CWTA was not applied to this project because the engineer’s estimate was under $1 million.
Present Situation
On August 2, 2018, one bid was received with the following result:
COMPANY NAME BID AMOUNT
SoCal Pacific Construction Corporation $216,228
dba National Coating and Lining Company (Murrieta, CA)
Engineer’s Estimate $236,297
The requirements of Stockton Municipal Code (SMC) section 3.68.090, Local Business Preference Ordinance, apply to this project. Application of the Local Business Preference Ordinance has no effect on the bid, as no local firms bid on the job. The Local Employment Ordinance, SMC section 3.68.095, also applies to this contract.
Prior to bid opening, several contractors were contacted to inform them of the project and to encourage bidding. SoCal Pacific Construction Corporation dba National Coating and Lining Company was the only bidder. SoCal Pacific Construction Corporation dba National Coating and Lining Company’s bid is below the engineer’s estimate, and it is unlikely that re-advertising the project will produce a lower bid price for the City.
The bid from SoCal Pacific Construction Corporation dba National Coating and Lining Company is responsive and regular in all respects and has the proper license to perform the work. Staff recommends Council approve the plans and specifications for the project, and award a Construction Contract to SoCal Pacific Construction Corporation dba National Coating and Lining Company in the amount of $216,228.
The project is in conformance with the City’s General Plan, pursuant to California Government Code section 65402, and is exempt from the requirements of CEQA as specified under the “general rule” at CEQA Guidelines, section 15061(b)(3). The activity does not qualify as a project and/or clearly could not have a significant effect on the environment and, therefore, CEQA does not apply. The resolution will approve the Notice of Exemption No. CE023-18 under CEQA. Construction is anticipated to be completed by the summer of 2019.
FINANCIAL SUMMARY
Sufficient funds are available in Account No. 437-7702-670 (CIP - Wastewater/Sanitary System Repairs) to cover the cost of this project.
There is no impact to the City’s General Fund or any other unrestricted fund as a result of taking the recommended action.
