City Council Meeting: April 25,
2006
Agenda Item: 1 J
To: Mayor and City Council
From:
Subject: City Hall Seismic Retrofit – Modification
to the Existing Professional Services Agreement.
Recommended
Action
This report recommends that the City
Council authorize the City Manager to negotiate and execute a modification to Contract
No. 8529 (CCS) with Black and Veatch in
an amount not to exceed $285,889 to expand engineering and architectural
services for the seismic retrofit of City Hall.
Executive
Summary
The project objective is to strengthen the existing
structural connections between the floor and the walls of City Hall. With the exception of code required
accessibility upgrades, the seismic retrofit project will not change the use or
look of any areas within City Hall. All
areas of construction will be restored to their current existing condition, with
the exception of the old jail, which will be retrofitted for temporary office
space in a manner that will not impact any potential future use.
The agreement requires modification due to three
factors:
1.
Added work scope
needs to be incorporated to expedite completion of the project (the creation of
two construction bidding documents), including the old jail cell area as temporary
office space for City staff.
2.
Inclusion of an elevator
to provide access to temporary offices located in the old jail area.
3.
Additional
criteria required to design City Hall as an Essential Facility, as defined in
Municipal Code 8.12.040.
This modification increases the consultant
fee from the original City Council authorization of $875,000 to a total not to
exceed $1,160,889.
Discussion
Background
Numerous buildings and other structures were
damaged in the City as a result of the January 1994 Northridge Earthquake. Although the City Hall building did not
sustain significant damage, the City commissioned a seismic evaluation of the
structure. This evaluation provided the
City and Federal Emergency Management Agency (FEMA) with cost-effective
remediation measures to bring City Hall to current code.
The scope of the seismic work includes structural engineering and associated upgrades, accessibility
enhancements, historic preservation, hazardous material abatement, construction
phasing, staff relocation, and cost estimating. The construction components of the structural
upgrade for this type of building typically involve anchoring the floors and roof
to the walls, providing additional floor stiffening, strengthening the existing
steel column to beam welds and other measures.
Integral to the retrofit project (and included in the
modification design scope of work) is the interior renovation to the existing
jail cells. This renovation will prepare
the old jail area as temporary office spaces for City Hall staff displaced by
retrofit work. The renovation is
scheduled to start early 2007 and be completed mid to late 2007. The retrofit project is scheduled to start
mid to late 2007 and be completed in early 2008.
The current estimated construction cost for
the project is $5 million. These funds
have been set aside by FEMA for this project. Construction is currently anticipated to start
in early to mid 2007 and be complete approximately 6-9 months later. It is planned that City Hall will remain open
and accessible during the course of the project although individual work units
may temporarily relocate within the building.
Previous Council
Actions
At the November
22, 2005 Council meeting, the City Council authorized the
negotiation of a professional services agreement with Black and Veatch for design
of the City Hall Seismic Retrofit project.
Contractor/Consultant Selection
On June 27,
2005, a Request for Qualifications was issued for design services and six
responses were received. A selection
committee consisting of staff from the Civil Engineering and Architecture and
the Building and Safety Divisions reviewed the qualifications. Four firms were short-listed and invited to
make individual presentations to the selection committee. Based on the qualifications and
presentations, the selection committee recommended Black and Veatch.
Public Outreach
This project may impact the operation of public access counters. The extent and duration of the impacts will be
known in mid to late 2006. If necessary, temporary public counters will
be designed as part of the interim old jail space renovation project and
constructed in the initial phases of construction. During construction, signage will be developed
to direct the public to the temporary location of the displaced public counter,
as well as any other temporarily relocated services. The temporary location will be fully accessible
including restroom facilities and access/egress path of travel to and within
the facility.
Budget/Financial Impact
The Federal Emergency Management Agency (FEMA) provided
funds for various upgrade projects throughout the City as a result of the 1994
Northridge Earthquake. These projects
are near completion with balances remaining.
Authorization was received from FEMA to utilize the remaining balances
for the seismic retrofit of City Hall.
Funds in the amount of $285,889 are available in
account E130748.555060.30000, “City Hall Seismic Retrofit.” The total cost of this professional services
agreement is not to exceed $1,160,889.
