Subject:Amendment No. 2 to an existing Consulting Services Agreement with Nolte Associates, Inc. Project Nos.:0662-6R4254-09;
0662-6R4255-10
BACKGROUND: (CONT'D)
engineering design services for the Vasco Road Safety Improvements project with Nolte Associates, Inc. The initial
project proposed to construct a permanent concrete median barrier along a 2.3 mile stretch of Vasco Road beginning
approximately 3 miles north of the Alameda County line to approximately 5.3 miles north of the County line. Since
then, County staff has identified construction funding sources for a 1.2 mile stretch of the project and has split the
project into two phases. The first phase is fully funded and includes $11,700,000 of American Reinvestment and
Recovery Act (ARRA) funds. Phase 1 is currently being advertised for bids with bids scheduled to be opened on
February 2, 2010.
Phase 2 of the project is currently at 65 percent design stage. This amendment provides budget to complete the plans
and specifications for Phase 2 within an accelerated time frame in anticipation of future availability of ARRA funds
for its construction. The environmental documents (both CEQA and NEPA) have already been approved for both
Phases 1 and 2.
With environmental approval already secured and design at 65 percent, Vasco Road Phase 2 is the County's top
candidate to receive ARRA funds. The completion of plans and specifications in Spring 2010 will be critical in order
to have this phase of the project poised to capture ARRA funds should additional funds become available in 2010.
Amendment No. 1 to the CSA was approved by the Board of Supervisors on August 25, 2009. Amendment No. 1
was for the additional design service items associated with Phase 1 of this project.
The following are some of the additional work items that gave cause for this amendment to Nolte's current CSA:
Phase 1 additional work:
• Design of temporary wildlife exclusion fence, gates and jumpouts.
• Preparation of addendum to Plans to eliminate retaining walls, provide layback slopes, modify, and revise
driveways between stations 251 and 262.
• Preparation of addendum to add the extension of retaining wall No. 6 from station 294+50 to 303 as a bid
alternative. Addendum includes all necessary changes to existing plans including drainage, wildlife crossings
and fencing, erosion control, and stage construction.
• Additional project management due to delays in the advertisement schedule by Caltrans and FHWA.
Phase 2 additional work:
• The original CSA provided design fee to bring Phase 2 up to a 65% design stage. This amendment provides
budget to complete plans and technical specifications. The budget includes an option to layback cut slopes
should the project schedule allow time for acquisition of right of way. If not, there is a budget item for design
of retaining walls to remain within existing road rights of way.
This amendment provides for completion of construction bid documents for both Phase 1 and 2 of the safety
improvement project (approximately 2.3 miles in length). This amendment also provides budget for bid and
construction support of both phases of work at the County's request.
Due to the accelerated schedule to meet ARRA funding requirements, Nolte initiated various out of scope design
tasks (described above) that are on the critical path prior to the projected approval date of the amendment on January
26. The consequence for deferring Nolte's start of this work was to jeopardize the $11,700,000+ in ARRA funds that
are programmed for construction of Phase 1 of this project.
CONSEQUENCE OF NEGATIVE ACTION:
The consequence for negative action by the Board is to jeopardize $11,700,000 in ARRA funds that are programmed
for Phase 1 of this project and may jeopardize future allocations of ARRA funding for Phase 2 of the project.
