OFFICE OF THE CITY MANAGER
NO. LTC # 297 -2011 LETTER TO COMMISSION
TO: Mayor Matti Herrera Bower and Members of the City Commission.
FROM: Jorge M. Gonzalez, City Manager r/ jv
DATE: November 22, 2011`
SUBJECT: Flamingo Park Pool Deck Improvements
The purpose of this Letter to Commission (LTC) is to inform the Mayor and members of
the City Commission of the Capital Improvement Projects Office (CIP) intent to utilize
previously reserved Fiscal Year 2008 -2009 Capital Renewal and Replacement
Contingency to fund the Flamingo Park Pool Deck Replacement Project.
At the September 16, 2008 Finance and Citywide Projects Committee meeting, during
discussion of the Capital Renewal and Replacement Fund Budget, it was recommended
that the structural assessment be funded and that the balance of the $304,000 project
budget be placed in contingency and be made available after completion of the.
assessment.
On February 4, 2011, the Capital Improvements Projects Office (CIP) commenced with
the Flamingo Park Pool Deck Structural Assessment Project to analyze and report on
the existing condition of the pool deck, investigate the probable causes of the cracking
that is occurring at the .existing deck finish, and provide recommendations for repair.
A Structural Assessment Study concluded that the existing cracks seen on the pool deck
topping surface are a reflection of small cracks on the top surface of the structural slab
below. These cracks are caused by thermal expansion and contraction of the existing
concrete, but are not structural failures. Consequently, the engineer concluded that the
pool deck is in good structural condition.
Since there is no way of controlling future cracks and that the application of a
cementitious topping will continue to telegraph any structural slab cracks to the deck
surface, the best solution would be the installation of a rubberized floor system. This
system consists of a poured -in -place and trowelled resilient, seamless rubber surface
installed over the existing structural slab. The rubber floor is composed of EPDM
(Ethylene Propylene Diene Monomer) rubber mixed with a cured aliphatic polyurethane
adhesive which will bond to the concrete sub base.
A cost estimate was previously prepared by CIP and the scope of work was reviewed
with Parks and Recreation. The project will be awarded to a contractor through an
existing General Services Administration Contract (GSA). The total surface square
footage of deck to be .coated is 30,361 S.F., resulting in a total cost per square, foot of
$6.85/S.F. Comparable options would be a 2" concrete topping slab with a broom finish
at approximately $7.70 per S.F. or mud -set 2 -3/8" thick concrete pavers at approximately
$8. S.F. The anticipated total cost of the project is $218,260.
