RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a Consulting Services Agreement (contract) amendment with Quincy Engineering, Incorporated (Quincy), effective November 3, 2020, to increase the payment limit by $275,000 to a new payment limit of $650,000 for civil design services for the Danville Boulevard-Orchard Court Complete Streets Improvements Project, and to extend the term from March 31, 2021 to December 31, 2022, Alamo area. County Project No.: 0662-6R4128, Federal Project No.: HSIPL-5928 (140) (District II)

FISCAL IMPACT:

This project, including this contract, will be funded by 66% Highway Safety Improvement Program Grant, 33% Measure J Regional Funds, and 1% Local Road Funds.

BACKGROUND:

This project will construct a roundabout at the Danville Boulevard/Orchard Court intersection in Alamo. The roundabout will include curb extensions, curb ramps, and entry medians at the roundabout to reduce vehicle speeds and improve pedestrian crossings. Sidewalks will be reconstructed through the corridor along with curb extensions and curb ramps in order to meet ADA requirements and accommodate existing mature trees in the sidewalk. The project includes a slurry seal, restriping of the roadway, and lane reconfiguration, as well as storm drain modifications, landscaping, stormwater treatment areas, signage, utility adjustments, and relocation of existing roadside features.

Quincy was selected to provide civil design services for the project after completing a request for proposal solicitation and technical proposal process. Public Works has successfully negotiated with Quincy to provide the civil design services.

Complications in the process of acquiring the necessary right-of-way for the project have increased the amount of design required, as well as the amount of time needed to complete the necessary design services. Therefore, an increase to the contract pay limit and contract term are required to complete the project.

CONSEQUENCE OF NEGATIVE ACTION:

Without Board of Supervisors' approval, this contract amendment will not be in effect. A delay in the design and subsequent construction of the Danville Boulevard-Orchard Court Complete Streets Improvements Project will occur, ultimately delaying the completion of the project. Project delay may also result in substantial additional project costs and jeopardize the funding.
