How large aircraft will move on the airfield
– taxi and park – could be demanding.
Florida, especially airports first in Tampa
and Orlando then in Miami and Fort
Lauderdale, expects to handle the Airbus
soon. Airport planning must assume and
prepare for both VLJ and NLA.
Thinking “Buck Rogers-ish” also means
consideration of commercial space travel
and spaceports. Launching GPS and
communication satellites into space occurs
today. Unmanned flights occur today
(remember, the military delivers rockets
and bombs this way).

What is being done to ensure a long
and healthy life for our bridges? Our
panelists discussed the “Life of a Bridge –
conception to retirement.”
Bridge inspection: The purpose of a
bridge inspection is to provide information
for immediate action to limit use of, or
close to traffic, any bridge that is shown
by inspection to be hazardous, said Mark
E. Bernhardt, P.E., Director of Facility
Inspection, Burgess & Niple, Inc. An
inspection also allows bridge maintenance,
repair or replacement to be programmed
effectively through early detection of
deficiencies.
Wave forces on bridge structures:
Rick Renna, Florida DOT’s Hydraulics
Engineer, said the initial work on the
AASHTO/FHWA Bridge Wave Task Force
has been completed. Guide specs have
been approved and future refinements in
design guide and countermeasures are
underway. He also discussed the ongoing
studies of bridge vulnerabilities in Tampa
and the Keys and the need for additional
research of wave tank tests.
Load Resistance Factor Rating (LRFR):
The shear capacity of existing reinforced
and prestressed concrete bridge members
shall be evaluated for permit loads, said
Andre Pavlov, Florida DOT Maintenance
Office. Jeff Pouliotte, Florida DOT
Maintenance Office, said one of the
challenges using LRFR load ratings to
permit overweight vehicles is many FDOT
bridges have low shear ratings using LRFR,
limiting mobility. All new FDOT bridges will
be LRFD & LRFR.
Service life of bridges: Richard Kerr,
Florida DOT Maintenance Office, said
FDOT policy requires the programming
for bridge repair or replacement within
six years when a structure becomes
structurally deficient or posted for weight.
The number of structural replacements will
slowly increase over the next 20 years,
but the increase will be manageable. A
good estimate of the structural service life
of FDOT bridges is 80 years. The bridge
repair program is a sound investment with
solid returns.

Is a public-private partnership (P3) the
right fit for the state Department of
Transportation’s (DOT) next project?
Consensus from a panel of industry
experts and its moderator emphasizes
reversing the question and asking first and
foremost: is this project truly a good
candidate for a public-private partnership?
Without that focus, a best-intentioned
approach to project delivery may miss
the mark. Identifying risks inherent in
project development and delivery, along
with operation and maintenance when the
improvement is in place, is the key issue.
That evaluation means taking a hard look
at the project from every angle, asking the
