RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute Amendment No. 6 to the consulting services agreement with Ove Arup and Partners California, Ltd. (ARUP) effective March 31, 2009, to increase the payment limit by $100,000 to a new payment limit of $1,250,990 with no change to the contract dates, to provide construction and bid support services for the Iron Horse Trail Pedestrian Overcrossing at Treat Boulevard, Contra Costa Centre area.

FISCAL IMPACT:

There is no impact to the County General Fund. This contract amendment allows for an additional $100,000 above the previously approved contract for $1,150,990, to be funded by Redevelopment funds (100%).

BACKGROUND:

On June 10, 2003, the Board approved the design of the pedestrian overcrossing at Treat Boulevard. This project provides for pedestrian and bicycle safety when crossing the heavily trafficked Treat Boulevard. The bridge will also link discontinuous sections of the Iron Horse Trail.

BACKGROUND: (CONT'D)

Arup is the designer of the Iron Horse Trail Pedestrian Overcrossing and has supplied the County with final plans, specifications, and estimate for the project. During the construction phase of the project, Arup will be asked to provide construction support services, including but not limited to, consultation and interpretation of the contract documents, assisting the County in preparing addenda or contract change orders to the plans and specifications, providing written response to contractor Request for Information, attending construction meetings, and reviewing shop drawings, and mock-ups.

This amendment provides for the following:
a. Construction support services.
b. Update rate schedule in Apppendix B to allow for the personnel changes in Appendix C.
c. Update key personnel and subconsultant list in Appendix C.

CONSEQUENCE OF NEGATIVE ACTION:

If the amendment is not approved, the consultant cannot be paid for the additional required work and the construction of this project may be delayed.
