GENERAL MANAGER'S RECOMMENDATION
recommendation
RECOMMENDATION: Recommend to the Board of Directors to:
A. Approve a Professional Construction Services Agreement with Tetra Tech, Inc. to provide construction support services for Uninterruptible Power Supply Improvements at Plant No. 1, Project No. P1-132, for an amount not to exceed $217,830; and
B. Approve a contingency of $21,783 (10%).
body
BACKGROUND
Tetra Tech, Inc. was selected as part of a competitive, qualifications-based solicitation process to design Uninterruptible Power Supply Improvements at Plant No. 1, Project No. P1-132. 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.
This project will replace 15 smaller commercial-grade Uninterruptible Power Supply (UPS) units by consolidating them into a single industrial-grade UPS in Power Building 8 to serve the northwest area of Plant No. 1. The project will also replace aged 480-volt electrical distribution equipment in the Maintenance, Rebuild Shops, Purchasing, and Warehouse areas.
RELEVANT STANDARDS
• Comply with California 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, preparation of standard operating procedures, providing startup assistance, and preparing record drawings.
PROPOSED SOLUTION
Approve a Professional Construction Services Agreement with the design consultant, Tetra Tech, Inc., to provide engineering support services during construction.
TIMING CONCERNS
Engineering support services will be required soon after the start of the construction Notice to Proceed. Construction is anticipated to start in February 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
November 2019 - Approved a Professional Design Services Agreement with Tetra Tech, Inc. to provide engineering services for Uninterruptible Power Supply Improvements at Plant No. 1, Project No. P1-132, for an amount not to exceed $784,680; and approved a contingency of $78,468 (10%).
ADDITIONAL INFORMATION
Tetra Tech, 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 Tetra Tech, 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 the authority levels of OC San’s Purchasing Ordinance. This project has been budgeted (Adopted Budget, Fiscal Years 2022-2023 and 2023-24, Section 8, Page 56, Uninterruptible Power Supply Improvements at Plant No. 1, Project No. P1-132) and the budget is sufficient for the recommended action.
