recommendation
RECOMMENDATION:
A. Approve a Professional Construction Services Agreement with CDM Smith Inc. to provide construction support services for Gisler-Red Hill Interceptor and Baker Force Main Rehabilitation, Project No. 7-65, for a total amount not to exceed $988,460; and

body
BACKGROUND
CDM Smith Inc. was selected as part of a competitive, qualifications-based solicitation process to design Gisler-Red Hill Interceptor and Baker Force Main Rehabilitation, Project No. 7-65. At the time of the solicitation, the Orange County Sanitation District (OC San) documented its intent to award a subsequent agreement to the design consultant for continuation of engineering services during construction.
The project will re-line approximately 12,000 linear feet of the Baker Force Main; replace corroded and damaged piping, valves, and valve vaults at the Main Street pump station; and re-line and repair approximately 8,600 linear feet of the Gisler-Red Hill Interceptor.
RELEVANT STANDARDS
• Comply with Government Code Section 4526 to engage the best qualified firm “on the basis of demonstrated competence and qualifications” and “negotiate fair and reasonable fees”
• Ensure the public’s money is wisely spent
PROBLEM
This project requires the design consultant to provide as-needed services during construction including submittal review, responding to the Contractor’s requests for information, reviewing construction change orders, participating in meetings, attending site visits, and preparing record drawings.
PROPOSED SOLUTION
Approve a Professional Construction Services Agreement with the design consultant, CDM Smith Inc., to provide construction support services during construction.
TIMING CONCERNS
Engineering support services will be required at the start of construction. Construction is anticipated to start in June 2023.
RAMIFICATIONS OF NOT TAKING ACTION
The engineering support services needed to facilitate and review construction activities would not be available by the Engineer of Record, which may negatively impact the contract execution.
PRIOR COMMITTEE/BOARD ACTIONS
September 2020 - Approved a Professional Design Services Agreement with CDM Smith, Inc. to provide engineering services for Gisler-Red Hill Interceptor and Baker Force Main Rehabilitation, Project No. 7-65, for an amount not to exceed $1,754,000; and approved a contingency of $175,400 (10%).
ADDITIONAL INFORMATION
CDM Smith Inc. has successfully furnished engineering services for the design of this project and their support services during construction will provide continuity through the completion of the project.
Staff negotiated with CDM Smith Inc. for these support services in accordance with OC San’s adopted policies and procedures. A review of the proposed price was conducted using estimated quantities of requests for information, submittals, meetings, site visits, change order review, and design revisions, as well as the level of effort for preparing record drawings. Based on this review, staff determined the negotiated fee to be fair and reasonable for these services.
CEQA
The project is exempt from CEQA under the Class 1 categorical exemptions set forth in California Code of Regulations Section 15301. A Notice of Exemption has been filed with the OC Clerk-Recorder.
FINANCIAL CONSIDERATIONS
This request complies with authority levels of OC San’s Purchasing Ordinance. This item has been budgeted (Adopted Budget, Fiscal Years 2022-2023 and 2023-24, Section 8, Page 32, Gisler-Red Hill Interceptor and Baker Force Main Rehabilitation, Project No. 7-65) and the budget is sufficient for the recommended action.
