RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute Contract Amendment No. 1 to the Consulting Services Agreement (CSA) with Hanna Engineering, Inc. (dba The Hanna Group)(Hanna), effective April 24, 2018, to increase the payment limit by $30,620 to a new payment limit of $304,620, for construction management services for the Canal Road Bridge Replacement Project (Project), for the period of June 6, 2017, through June 30, 2018, Bay Point area (District III) County Project No. 0662-6R4080/Federal Project No. BRLO-5928(108)

FISCAL IMPACT:

This project, including the CSA, is funded by 100% Federal Highway Bridge Program Funds.

BACKGROUND:

BACKGROUND: (CONT'D)

The project consists of removing an existing concrete slab bridge and pedestrian bridge, construction of a new concrete precast/prestressed concrete slab bridge, pavement reconstruction, temporary and permanent waterlines, drainage improvements, erosion control, signing and striping. Hanna was selected to provide construction management services for the project.

Proposed Amendment No. 1 will amend the payment limits in order to provide additional construction management services that are needed to successfully complete the project. Construction delays due to girder procurement issues caused a need to extend the construction duration by approximately 3 months requiring additional consultant construction management services.

CONSEQUENCE OF NEGATIVE ACTION:

The project completion would be delayed and Federal funds would be in jeopardy.
