COMMISSION ITEM SUMMARY
Condensed Title:
A Resolution of the Mayor and City Commission of the City of Miami Beach, Florida, appropriating
$1,300,000, from the General Fund Capital Reserve, to fund the unforeseen additional structural repairs
and project contingency required to complete the Historic City Hall Building Renovation Project.
Ke Intended Outcome Su orted:
Well Maintained Facilities
Item Summarv/Recommendation:
After all the demolition was performed on the exterior facade and interior portions of the existing exterior
walls of the Historic City Hall Building, additional structural deficiencies were found that required the
complete replacement of structural beams, columns, and concrete block walls of the building. Additionally,
the existing windows of the building were attached in a manner that is no longer in compliance with the
Building Codes. The installation of new impact resistant windows will require the installation of reinforced
concrete "tie" columns to properly attach the new window frames. No "tie" columns were found around the
existing windows when the interior walls were removed. Because of the significant additional structural
repairlreplacement needs and the requirements of window "tie" columns and lintels, the Property
Management Director developed a cost estimate of the additional structural work including project
contingencies and any additional collateral project needs.
As required by Resolution No.2005-25857, the Administration hereby requests that the Mayor and City
Commission appropriate a total of $1 ,300,000, from the General Fund Capital Reserve amount deemed
necessary to complete the additional structural repair work and to bring the Historic City Hall Building
Renovation Project to completion.
Adopt the Resolution.

ANAL YSIS
On July 12, 2006, the Mayor and Members of the City Commission ratified Resolution
No. 2006-26274, approving the Property Management Director's contract to National
Concrete Preservation, Inc., in the total amount of $1,911,095, to provide for the
removal of the exterior stucco and replacement with fiber reinforced stucco, the
removal of all windows and replacement with hurricane resistant impact resistant
windows and frames, and the repair or replacement of all damaged exterior decorative
moldings, cornices, and balusters at the Historic City Hall Building.
Many serious structural deficiencies were revealed during the initial removal of the
exterior stucco. These deficiencies included concrete loss, reinforcement corrosion
including structural steel beams and columns, brick wall damage, and window
anchoring systems that were missing. The Property Management Director contacted
BEA International, Inc., (Engineer of Record) to determine the structural damages, to
the extent limited by the accessibility of the damaged locations at the time of the
inspection. The engineers also based their structural findings on their observations of a
typical window and frame with the exterior stucco removed. The engineer was also
requested to develop a structural repair plan based on his observations and findings.
The structural plans developed by the engineer provided repair methods for the
building's structural columns and beams for up to a 50% replacement requirement in
which the initial structural change order increase was based. The Mayor and City
Commission also approved the appropriation of an additional $1,900,000 from the
Capital Reserve account for project costs and contingencies and approved the
ratification of the Property Management Director's change order to National Concrete
Preservation, Inc., in the amount of $1,759,504, to provide for the known structural
repair needs at the Historic City Hall Building.
As work progressed, and windows and interior surfaces were removed, the extent of the
unforeseen structural damages increased significantly. This was especially true on the
base two floors of the building and the ninth floor that houses Police communications
equipment and mechanical equipment rooms. The two base floors and the ninth floor,
unlike the tower that utilized steel "I" beams in the construction method, were built using
reinforced concrete columns and beams. When exposed, these structural elements were
found to be well beyond repair due to severe spalling and critical loss of the reinforcing
steel within the concrete. The beams and columns and the terra cotta bricks that made up
the exterior walls on these floors required 100% replacement. The requirement of this
work included the need to bring in heavy shoring including temporary steel beams. These
beams and heavy shoring are necessary to support the floors and roofs of the affected
floors while the exterior walls sections were being completely replaced.
Another significant unforeseen structural problem found in the building was with the
existing windows. The windows in the tower section were attached to metal studs on the
inside of the building which are not allowed by code. Because of the attachment method
requirements of impact resistant windows, concrete "tie" columns are required to be
installed to support the new hurricane impact resistant window frames. Additionally, the
existing windows sizes were beyond the dimensions previously approved by Miami-Dade
County product approvals. To overcome this problem, the Property Management Director
hired a structural engineer that specializes in window construction to develop design
specifications and the wind load calculations required to meet Miami-Dade product
approvals. This process has been completed and the windows have been approved by the
Building Department's Structural Engineer and recently (March 5th) by Historic
Preservation for historic appropriateness for the building. The windows were ordered on
the day the approvals were obtained.
Due to the additional structural damage found in the building, a cost estimate was
requested to complete the repair and replacement of the structural beams and
columns, and to provide for the installation of the structural 'tie" columns required for
the installation of the new impact resistant windows and frames for the building.
The Administration recommends that the Mayor and members of the City Commission
appropriate $1,300,000 from the General Fund Capital Reserve, for project costs and
contingencies, to provide for the additional structural repair needs at the Historic City
Hall Building.

SUBJECT: Historic City Hall Renovation Project
The purpose of this LTC is to inform you about the status of the undergoing repairs and renovations
to the Historic City Hall Building.
On July 12, 2006, the Mayor and Members of the City Commission ratified Resolution No. 2006-
26274, approving the Property Management Director's contract to National Concrete Preservation,
Inc., in the total amount of $1 ,911 ,095, to provide forthe removal of all the Historic City Hall exterior
stucco surfaces and replacement with fiber reinforced stucco; the removal of all windows and
replacement with hurricane impact resistant windows and frames; and the repair or replacement of
all damaged exterior decorative moldings, cornices, and balusters.
Many serious structural deficiencies were revealed during the initial removal of the exterior stucco.
These deficiencies included concrete loss, reinforcement corrosion including structural steel beams
and columns, brick wall damage, and window anchoring systems that were missing. The Property
Management Director contacted BEA International, Inc., (Engineer of Record) to determine the
structural damages, to the extent limited by the accessibility of the damaged locations at the time of
the inspection. The engineers also based their structural findings on their observations of a typical
window and frame with the exterior stucco removed. The engineer was also requested to develop a
structural repair plan based on his observations and findings. The structural plans developed by the
engineer provided repair methods for the building's structural columns and beams for up to a 50%
replacement requirement in which the initial structural change order increase was based. The Mayor
and City Commission also approved the appropriation of an additional $1,900,000 from the Capital
Reserve account for project costs and contingencies and approved the ratification of the Property
Management Director's change order to National Concrete Preservation, Inc., in the amount of
$1,759,504, to provide for the at the time known structural repair needs at the Historic City Hall
Building.
As work progressed, and windows and interior surfaces were removed, the extent of the unforeseen
structural damages increased significantly. This was especially true on the base two floors of the
building and the ninth floor that houses Police communications equipment and mechanical
equipment rooms. The two base floors and the ninth floor, unlike the tower that utilized steel "I"
beams in the construction method, were built using reinforced concrete columns and beams. When
exposed, these structural elements were found to be well beyond repair due to severe spalling and
critical loss of the reinforcing steel within the concrete. The beams and columns and the terracotta
bricks that made up the exterior walls on these floors required 100% replacement. The requirement
of this work included the need to bring in heavy shoring including temporary steel beams. These
beams and heavy shoring are necessary to support the floors and roofs of the affected floors while
the exterior walls sections were being completely replaced.
Another significant unforeseen structural problems found in the building was with the existing
windows. The windows in the tower section were attached to metal studs on the inside of the
building which are not allowed by code. Because of the attachment method requirements of impact
resistant windows, concrete "tie" columns are required to be installed to support the new hurricane
impact resistant window frames. Additionally, the existing windows sizes were beyond the
dimensions previously approved by Miami-Dade County product approvals. To overcome this
problem, the Property Management Director hired a structural engineer that specializes in window
construction to develop design specifications and the wind load calculations required to meet Miami-
Dade product approvals. This process has been completed and the windows have been approved
by the Building Department's Structural Engineer and recently (March 5th) by Historic Preservation
for historic appropriateness for the building. The windows were ordered on the day the approvals
were obtained.
To meet the requirements of the building code and historic preservation that any structural
deficiency found with the Historic City Hall Building must be repaired in a manner consistent with the
original historic design ofthe building, the Administration will be requesting an appropriation offunds
and a change order increase in the amount of $1,300,000 for the additional structural repair work
and the addition of window "tie" reinforced concrete columns that are required on the project.
The structural repair work on the project is approximately 85% complete. Other elements on the
project such as replacement of the HVAC air handling systems are approximately 95% complete.
This work required creating large openings in the exterior walls of the building just to get the
equipment into the air handling rooms. The complete renovation of the two elevators and the
antique elevator equipment in the building is currently out to bid and the Property Management
Director expects the work to be under contract in April. The Property Management Director expects
to start receiving windows within the next three weeks and the installations will begin immediately.
Once windows are installed, the final plastering and finishing process of the building will begin.
Work on the project has never stopped in spite of the major unforeseen building structural
deficiencies found during different stages of the project, and taking into consideration the
requirements to obtain mandatory inspections from the Special Inspector of record for the project
and the Building Department. While from Washington Avenue it may appear that work has slowed,
the majority of work being performed has been on the bottom two floors and ninth floor of the
building which are hidden from view due to the scaffolding requirements of the project. With the
structural repairs on-going and the final approvals of the windows obtained, the completion of the
structural and fac;ade renovation project of the Historic City Hall Building is still on track and
estimated to be substantially complete by December 2007. Attached are pictures of some of the
structural problems encountered during the project.
Should you have any questions about this project, please do not hesitate to contact me.
