On-Call Roundabout Design Peer Review Request for Proposals (RFP)

1. APPROVE Request for Proposals for On-Call Roundabout Design Peer Review, subject to counsel approval;
2. AUTHORIZE staff to publish the RFP, and return to the Board of Directors with a recommendation for approval of a consultant; and
3. APPROVE the use of funds from approved project budgets for this contract for an estimated amount not to exceed $640,000.

This request for proposals will seek bids from qualified consultants to assist the agency with independent design review for roundabout projects currently being considered and prepared by Caltrans, including the SR 156 / Castroville Boulevard Interchange Project and proposed roundabout alternatives that may be included in the environmental determination for the SR 68 Scenic Corridor Project.

The costs for roundabout design peer reviews will be covered by Measure X funds included in individual project's development budget. The consultant selected to perform roundabout design peer reviews will be issued task orders to perform activities described in the attached scope of work to conduct independent design review for considering potential alternatives in the environmental review of roundabout projects and at key points throughout the design process for approved roundabout projects.   

The total not to exceed amount of the contract is estimated to be $640,000 based on staff's independent cost estimate. The average cost for independent peer review per roundabout project is expected to be less than 1% of the overall project cost. Other roundabout projects may activate the option to issue task orders for the selected roundabout design peer review consultant.  

The Transportation Agency for Monterey County is the responsible agency for implementing two anticipated regional projects on the State Highway System, for which Caltrans is designated as the lead agency and will prepare designs for roundabouts that are being considered or are approved in each project.

The SR 156 / Castroville Boulevard Interchange Project has already received environmental clearance and approval by Caltrans.  The project includes three roundabouts in its design, one for eastbound ramp intersection, one for the westbound ramp intersection, and one for the new Castroville Boulevard alignment intersection with the old Castroville Boulevard.

The SR 68 Scenic Corridor Project study proposes nine roundabouts included in the preferred alternative, which would replace the existing traffic signals along the corridor from Salinas to Monterey.  This project is currently undergoing preliminary engineering and environmental review.  Both projects will be designed by Caltrans.  The consultant selected to perform roundabout design peer reviews is anticipated to conduct independent design review for all twelve roundabout included in these two projects at key points throughout the environmental review and design process.
