BACKGROUND
On December 5, 2006 the Council accepted a progress report on the Mary Avenue Bicycle
Footbridge Project. The project is a single span cable stayed bridge over Interstate Route 280
connecting an established bicycle trail system on Mary Avenue in Cupertino on the south side of
1-280 to Mary Avenue in Sunnyvale on the north. The design concept, developed by city staff and
the design consultant, Biggs-Cardosa Associates, had been approved by the Council on February
1,2005.
The project was advertised for competitive bidding on March 28, 2007 and bids were received
and opened on May 3, 2007 resulting in two bids, both of which were in excess of $12 Million
which represented a variation of 100% over the Engineer's estimate, On Staff's recpmmendation,
the Council acted on May 10, 2007 to reject both bids. .
14 - 1 1
On August 21 ~ 2007, the Council approved a design alternative for the bridge to be constructed of
structural steel in lieu of the previously approved pre-stressed concrete design and approved
design services contracts with HNTB~ Inc. in the amount of $775,000 and LERA Associates in
the amount of $150,000. Staff was requested by the Council to report back in late September with
a new Engineer's estimate based on the steel design and with appropriate recommendations for
budget augmentations to proceed with the bidding of the project
On September 18, the Council received a Report of the Cost Estimates and Bid Package for the
steel bridge design of the Mary Avenue Bicycle Footbridge. The final estimate of probable cost
for the bridge construction was determined to be $10~205,OOO. The final estimate of the project
budget was detennined to be $17, 435,000.
In consideration of that report, the Council approved a project budget augmentation to support the
bid process in the amount of$ 5,701,000 in FY 2007-2008 and in the amount of $1,000,000 in
FY 2008-2009 for the Mary Avenue Bicycle Footbridge Project. This budget augmentation was
approved with the understanding that the staff would seek additional funding from the Valley
Transportation Authority (VTA), the primary sponsor of the project In addition, the Council
authorized the Director of Public Works to advertise the project for competitive construction bids.
VTA Funding Augmentation
As part of the Council request to seek other funding, Staff has initiated discussions with the VT A
to determine what, if any, funding might be available with the VTP 2030 Bicycle Fund. Staffhad
requested that the VTA consider the status and certainty of other projects in the County, and, to
the greatest extent possible, advance additional funding from the VT A Bicycle Expenditure Plan.
The VTA staff recommended that funding be increased for the Mary Avenue Bicycle Footbridge
in an amount of $3~350,000 for a total VTA funding commitment of $10,350,000. with the
understanding the City would provide an equal match in additional funding as follows:
VTP 2030 Project Bll
$ 10,000,000
Additional VT A Funding (11-01-07)
$ 3.350.000
Tota~ Proposed VTA Funding
$ 10,350,000
On November 1~ 2007, following approvals by the VTA Bicycle Pedestrian Advisory
Commission and substantial consensus from the Technical Advisory Committee (T AC) and
Congestion Management Planning and Program Committee (CMPP) the VTA Board considered
the VT A staff recommendations. The Board voted unanimously to approve the funding allocation
recommended by staff in the amount of $3,350,000 for a total VTA commitment to the project of
$1O,350~000. '
This amount, combined with the prior funding allocations, including an additional amount of
General Funds from the City as noted below will fully fund the estimated cost of the project..
The steel bridge project was advertised for competitive biding on September19~ 2007 and bids
were received and opened on November 13, 2007.

REPORT ON CONSTRUCTION BIDS
Construction bids were received and opened on November 13, 2007 with the following results:

FCI Constructors Inc.

(280/0)
s noted above the apparent low bidder, Golden State Bridge, Inc. is $2,875,097 below the
engineer's estimate of $10,205,000, a variance of -28% which is an exceptional price for this
project. In addition, there were several bid alternates included which were estimated to be a total
of $178,000. This was not included in the project budget.
However, now that we the City has received such a good price, staff is recommending that the
alternates be included in the award of the contract. The low bid from Golden State Bridge, Inc. ,
inclu~ed a price of $139,832 which is well below the estimate. A list ofthe alternates is shown on
Attachment B.
The combination of the low bid and the add alternates brings the contract award to a total of
$7,469,735. That bid price, if accepted will bring the final project cbst (rounded to $1,OOO's) to a
total of $14,800,000. A revised project budget which reflects the low bid and the additional VTA
Funding, is shown on Attachment A.

PROJECf ART
City policy requires that 1/4% of the constructed cost of a project be allocated for the installation
of public art. Because of the visibility and importance of this bridge project a 1.4 % art allocation
($145,000) was included in this project budget. '.
The concept approved by the Council, and on which the Fine Arts Commission concurred, was
developed by Tom Aidala, a noted artist and architect, and will place sculptures of a family of
California native quail elevated on a cluster of granite boulders, and a red-tailed hawk elevated on
a pedestal near the approach path on the Cupertino side of the bridge. An additional item on this
agenda is the authorization for the City Manager to negotiate and execute a final design and
sculpture fabrication contract in an amount not to exceed $145,000.
ANNUAL FACILITY MAINTENANCE COSTS
The City's agreement with Caltrans requires that the City, assume responsibility for the care and
maintenance of the bridge superstructure (towers, cables, bridge deck and lighting, etc.) and the
pathways on either side while Caltrans will be responsible for maintenance in their right of way
along the freeway. This arrangement was established because it is important that the City have
control over the bridge and its appearance. In addition it will ensure that no freeway signage or
other fixtures are arbitrarily placed on it.
Very little in the way of maintenance costs is expected on the new bridge for some years, and
everything planted will be on a warranty for up to six months. There will be an annual cost for some
minor maintenance, but it is estimated that the cost will not exceed $10,000 annually after the first
year.
FISCAL IMPACT
An additional amount of funding for the project of $ 716,000 is required. The following approach is
recommended for funding of the project and award of the Construction contract to the low bidder.
Uncommitted General Funds - Gas Tax Funds $ 716.000
Current CIP Savings through FY 2006-2007 $ 116,000
Gas Tax Reserves $ 600~OOO
Total Unallocated GF $ 716,000
14 -4 4
Smce this is not new money but is instead either fuD.ds that were achieved through savings duriI
,the course of the budget year or additional revenue not included in the budget, the additiOnal
funding in the amount of $ 716,000 for this project is proposed to be advanced from these sources.
Lastly, the Council, on September 18, 2007 had authorized the approval of a Project Budget
Augmentation from the Stevens Creek Corridor project budget to support the bid process in the
amount of $ 5.701 Million in FY 2007-2008 and in the amount of $1.000 Million in FY 2008-
2009 for the Mary Avenue Bicycle Footbridge Project. Since the amount of the low bid is now
known and staff has recommended appropriate funding to award the contract, this allocation is no
longer necessary and the funds for the Stevens Creek Corridor should be restored to the project.
