DCENTRALSAN MEETING DATE: AUGUST 14, 2023 BOARD OF DIRECTORS POSITION PAPER DRAFT SUBJECT: REVIEW DRAFT POSITION PAPER TO AUTHORIZE THE GENERAL MANAGER TO EXECUTE A PROFESSIONAL ENGINEERING AGREEMENT WITH CAROLLO ENGINEERS, INC. IN AN AMOUNT NOT TO EXCEED $1,150,000 MILLION FOR DESIGN OF THE CONTRA COSTA TRANSIT AUTHORITY(CCTA)A-LINE RELOCATION, DISTRICT PROJECT 100050 SUBMITTED BY: INITIATING DEPARTMENT: DANA LAWSON, SENIOR ENGINEER ENG-PDS-DIVISION MANAGER REVIEWED BY: EDGAR LOPEZ, CAPITAL PROJECTS DIVISION MANAGER DANEA GEMMELL, PLANNING AND DEVELOPMENT SERVICES DIVISION MANAGER GREG NORBY, DEPUTY GENERAL MANAGER OF ENGINEERING AND OPERATIONS ROGER S. BAILEY, GENERAL MANAGER ISSUE The Board of Directors (Board) authorization is required for the General Manager to execute professional engineering agreements in an amount greater than $200,000. BACKGROUND Contra Costa Transit Authority (CCTA) is improving the State Route 4/ Interstate 680 interchange. In advance of the next stage of improvements, CCTA requires the relocation of Central San's 84-inch reinforced concrete pipe (RCP) commonly referred to as the A -Line along the east side of Interstate 680, as well as a portion of 8 and 12-inch mains on the west side of Interstate 680. Approximately 2000 linear feet (LF) of the A -Line must be relocated along Berry Drive in unincorporated Contra Costa County, as shown in Attachment 1, and the existing facilities will be abandoned in -place. On June 15, 2023, the Board approved a Utility Relocation Agreement with CCTA to reimburse all costs for the design phase for this project; a subsequent agreement will be executed for the construction costs prior to that phase of the project. Staff prepared and posted a Request for Proposal (RFP) to PlanetBids on May 30, 2023, notifying all interested firms of the proposed scope, qualifications, and schedule. Additionally, staff emailed the RFP to August 14, 2023 EOPS Regular Committee Meeting Agenda Packet - Page 4 of 64 Page 2 of 4 six consultant firms experienced in large diameter pipe design and met with five firms to discuss the project specifics, which included CDM Smith, Brown & Caldwell, Carollo Engineers, Delve Underground (formerly McMillan Jacobs Associates), and Woodard & Curran. While several firms had expressed interest, only one proposal was received on July 14, 2023 from Carollo Engineers for $999,875. Several qualified firms responded that their resources were already committed to other projects during this twelve- month design schedule. Staff reviewed the proposal and then Carollo participated in an interview on August 11, 2023 per the evaluation criteria published in the RFP. Staff confirmed that Carollo Engineers meets the experience and qualification requirements, and has a reasonable scope, schedule and budget. Carollo Engineers designed the last large sewer project for Central San (A -Line Relief Interceptor, Phase 2A, District Project No 5980) which installed a 96-inch interceptor across Buchanan Golf Course in 2008. Furthermore, Carollo Engineers has subcontracted with the same geotechnical engineers from that project; and will subcontract with other local firms that have worked on Central San projects for surveying, utility locating and potholing. Key deliverables from this Professional Engineering Services Agreement are development of Final Plans and Technical Specifications and an Engineer's Estimate of Probable Cost for submittal to CCTA by September 2024 in compliance with the Utility Reimbursement Agreement that was executed in June. The Engineer's Estimate of Probable Cost will aid CCTA in determining its full funding requirement for both the utility relocation and the larger State Route 4/1 nterstate 680 interchange improvement project. If there is insufficient funding, then CCTA may further phase this last stage of the interchange improvement project and staff anticipates that construction of the A -Line relocation would be concurrent with their first phase, such that the second phase would construct the fly -over ramp that is prompting the relocation of the A -Line along Berry Drive. Staff is requesting that the Board authorize execution of an agreement with a cost ceiling of $1,150,000 million. This includes a contingency of 15-percent for amendment(s) on a task -specific basis for additional scope or services that may be needed, but are not currently anticipated, such as a constructability review or additional permitting assistance. This contingency will ensure the amendment(s) could be processed up to the authorized cost ceiling without returning to the Board to facilitate compliance with the September 2024 deadline in the Utility Relocation Agreement with CCTA. California Environmental Quality Act (CEQA) At its meeting on June 15, 2023, the Board found this project to be exempt from CEQA. ALTERNATIVES/CONSIDERATIONS The Board may decline authorization of the agreement. This is not recommended as the agreement provides design services for relocation of the A -Line which is required by CCTA. FINANCIAL IMPACTS While this project is included in the FY 2023-24 Budget on page 236, there will be no net impact to the Capital I mprovement Budget (CI B) or 10-Year Capital I mprovement Plan (Cl P) since the costs will be reimbursed by CCTA as outlined in the Utility Relocation Agreement. The design phase will be fully reimbursed under the current agreement and a subsequent agreement will be executed for the construction costs since the existing 84-inch, 12-inch and 8-inch sewer pipelines are lawfully maintained in their present locations pursuant to rights superior to those of CCTA and, per California Streets and Highways Code Section 705, no credit is allowed due to age for publicly owned sewers.
