Subject: STATUS REPORT ON MISCELLANEOUS BRIDGE CAPITAL PROJECTS
Recommendation:
The following report is provided for informational purposes
and no action is required.
Background:
Golden Gate
Bridge Public Safety Railing:
The Board, by
Resolution No. 97-3 04, authorized execution of a Professional
Services Agreement with Imbsen and Associates in an amount
not to exceed $226,316 for the design and preparation of
plans, specifications and bidding documents for a public
safety railing located between the sidewalk and the roadway
on the east and west sides of the Bridge. Engineering services
are approximately 90% complete. On August 30, 1999, the
District was notified that the State Historic Preservation
Office had approved the project and that the Federal Highway
Administration had issued a Categorical Exclusion Determination
for the project. On October 19, 1999, staff presented the
project to the BCDC Design Review Board. Staff and the consultant
are presently working on responding to issues concerning
the height of the railing and the placement of the railing
in relation to the edge of the roadway raised by the BCDC
Review Board. It is anticipated that these issues will be
resolved with BCDC in the next few months and that the project
will be ready to advertise for bids in May of this year.
Funding in the amount of $2,520,000 (18% Federal! 82% District)
is included in the Fiscal Year 1999/2000 Bridge Division
Capital Budget. The District is working closely with Senator
Burton to seek a state appropriation to cover the District
share of the project cost.
GGB Movable Median Barrier: The Board, by Resolution No.
99-175, authorized execution of a Professional Services
Agreement in the amount of $35,000 with Parsons Brinckerhoff
for a feasibility study of the approved concept for a movable
median barrier consisting of four issues:
· Develop
movable barrier end treatment and anchorage, including a
cushioning system
at the Toll Plaza.
· Evaluate transfer vehicle storage requirement at
the north end of the Bridge.
· Evaluate lane markings on the Bridge.
· Develop emergency response procedure for accidents
or incidents that require emergency response across the
barrier.
Issues pertaining
to indemnification and insurance requirements have been
resolved with Parsons Brinckerhoff, and the Professional
Services Agreement was executed on February 18, 2000. The
District Engineer has scheduled a project meeting with Parsons
Brinckerhoff and Barrier Systems Inc. to start the project
It is anticipated that this phase of the project will require
approximately four months. The Board has also directed the
District Engineer to evaluate two additional issues: the
impact of narrow lanes adjacent to the baffler on traffic
operations and the impact of an accident on the Bridge with
the baffler in place on traffic operations. These items
will be evaluated utilizing the results developed in the
first phase study. Board authorization to augment the initial
study’s scope of work will be requested to study the additional
items when sufficient data has been developed in the first
phase. There is currently no funding available for construction
of this project.
Golden Gate Bridge Suicide Deterrent:
The Board, by
Resolution No. 97-106, authorized the development and construction
of a suicide deterrent prototype utilizing the Z-Clip system.
After reviewing the Z-Clip prototype, the Board rejected
the concept of erecting a suicide deterrent such as a Z-Clip
system at the roadway level because of its visual impact.
Staff was directed to develop an alternative system below
the roadway level. Staff has developed several alternatives
but has been unable to develop a deterrent that meets three
basic criteria: visually pleasing, reasonable in cost, and
effective. Staff continues to evaluate new technologies
and materials applicable to the development of a suicide
deterrent. There is currently no funding available for construction
of this project.
Fiscal Impact:
There is no fiscal impact relative to this status report.

County Owned Transportation Empire, which excluded public
safety at this present time.
