Consider Action on a Resolution Approving the Agreement Between the Town of Addison and Garver, LLC. for Professional Engineering Services Related to the Winnwood Road Bridge Class Culvert Outlet Armoring Project and Authorizing the City Manager to Execute the Agreement in an Amount not to Exceed $97,682.

BACKGROUND:

In early 2020, Garver, LLC (Garver) was tasked to perform an engineering condition assessment of the Winnwood Road bridge culvert and provide recommendations on rehabilitation and repair. Their report recommended a new riprap concrete apron be constructed to protect against further scouring and undermining of the wing and toe walls. This project is identified as high risk in the Town Asset Management Plan.

Garver was qualified through a Request for Qualifications process in 2017 to perform design, project management, and construction management related services for the Town. Garver was selected to perform the design work for the Winnwood Road Bridge Class Culvert Outlet Armoring due to their experience and familiarity with the project.

Garver will provide the following services under this contract:

Survey of the project area and existing utility locations
Hydraulic analysis
Design of the drainage improvements
Bid phase services
Design Support During Construction (Construction Administration) such as review of shop drawings and requests for information (RFIs)

Design for this project is anticipated to take 7 months to complete. This project is budgeted in the Storm Water Utility Fund.

RECOMMENDATION:

Administration recommends approval.
