body
Summary
The Municipal Utilities Department (MUD) follows a Condition Assessment Program for the City’s sewer infrastructure comprised of Closed Circuit Televised Video (CCTV) inspection, pipe cleaning, and engineering evaluation. This program generates a prioritized list of replacement and/or rehabilitation projects for inclusion in the City’s Capital Improvement Plan (CIP). A project to rehabilitate a large diameter pipe segment along Sierra Nevada Street was identified and included in the Fiscal Year (FY) 2018-23 CIP. The project will rehabilitate approximately 1,900 linear feet of 36-inch sewer trunk line along Sierra Nevada Street between Hazelton Avenue and Worth Street (Attachment A - Vicinity Map).
On October 1, 2018, the City advertised a Request for Proposals (RFP) for the design of the Sierra Nevada Street Sanitary Sewer Rehabilitation project. On November 8, 2018, three firms submitted proposals for this project. A committee evaluated the proposals and found Kjeldsen, Sinnock & Neudeck, Inc. (KSN) of Stockton, CA, to be the most qualified and highest ranked firm.
It is recommended that Council approve a motion authorizing the City Manager to execute a Professional Services Contract in the amount of $77,538 with KSN. It is anticipated that the design will be completed by December 2019. The project will then be advertised for construction bids, with overall project completion anticipated by December 2020.
DISCUSSION
Background
The MUD follows a Condition Assessment Program for the City’s sewer infrastructure comprised of CCTV inspection, pipe cleaning, and engineering evaluation. This program generates a prioritized list of sewer replacement and/or rehabilitation projects for inclusion in the City’s CIP. The Program identified a 36-inch sewer trunk line along Sierra Nevada Street for rehabilitation. The project will rehabilitate approximately 1,900 linear feet of 36-inch sewer trunk line along Sierra Nevada Street between Hazelton Avenue and Worth Street (Attachment A - Vicinity Map). The project was included in the FY 2018-23 CIP.
Present Situation
On October 1, 2018, the City advertised an RFP for the design services of the Sierra Nevada Street Sanitary Sewer Rehabilitation project. On November 8, 2018, three proposals were received from the following firms:
• Kjeldsen, Sinnock & Neudeck, Inc. (Stockton, CA)
• West Yost Associates (Davis, CA)
• CSG Consultants (Pleasanton, CA)
A committee comprised of Public Works and MUD staff evaluated and ranked all proposals based on each firm’s understanding of work, experience with similar kinds of projects, staff qualifications and technical ability, project approach, and local preference.
KSN received the highest ranking, based on the noted criteria, and was determined to be the most qualified firm for this project. Staff negotiated a fee of $77,538 with KSN for design services. This fee is approximately seven percent of the estimated construction cost, which is reasonable for a project of this size and complexity. It is anticipated that the design will be completed by December 2019. The project will then be advertised for construction bids, with overall project completion anticipated by December 2020.
Staff recommends Council approve a motion to award a Professional Services Contract in the amount of $77,538 to KSN for design services of the Sierra Nevada Street Sanitary Sewer Rehabilitation project (Attachment B).
Findings
Pursuant to Stockton Municipal Code (SMC) section 3.68.070, Council may approve findings which support an exception to the competitive bidding process. These findings include:
1. The City does not have sufficient staff available to design this project.
2. The scope of the design services requires an engineering firm experienced in sanitary sewer rehabilitation technologies.
3. Use of the RFP process is appropriate for this Professional Services Contract, because it relies on the evaluation of professional qualifications and performance as the basis for selection of a vendor. Use of this criteria helps ensure selection of a vendor that will provide the highest quality professional service which is in the public interest.
4. The City negotiated a contract following solicitation of competitive proposals in accordance with SMC section 3.68.070.A.3.
The recommended motion will approve a Professional Services Contract with KSN in the amount of $77,538.00 for the Sierra Nevada Street Sanitary Sewer Rehabilitation, Project No. M18029.
FINANCIAL SUMMARY
There are sufficient funds available in Account No. 437-7702-670 (CIP - Wastewater/ Sanitary Sewer Deficiency Improvements) to award the Professional Services Contract in the amount of $77,538.
There is no impact to the City’s General Fund or any other unrestricted fund as a result of taking the recommended action.
