We specialize in the design, detailing, construction and erection techniques for
cast-in-place and pre-cast concrete segmental box bridges. We also have extensive
experience with major, continuous-span structural steel plate girder and box girder
bridges.
In particular, for seven years with the FDOT Structures Design Office, Clark T.
Williams, P.E., SDR Chief Engineer, was responsible for the review and approval
of all major and complex bridge designs performed by consultants. For an additional
five years serving as the FDOT State Construction Structural Engineer, Clark was
responsible for assisting in the construction of those same bridges that he helped
design. He has worked as and worked with design and construction personnel, CEI
consulting firms, contractors and specialty subcontractors. His significant field
experience serves to compliment his extensive design experience.
Clark has been involved continually over the past 20 years with the design and construction
of the major bridges throughout Florida, including the Sunshine Skyway Bridge. He
has served as a Design/Build Engineer for contractors as well as a Specialty Engineer.
He is well versed in all aspects of construction contracts.
During the three-year erection time of the Sunshine Skyway Bridge Main Span, he
served as a Specialty Engineer to the contractor, Paschen Contractors, Inc. He designed
and provided field inspection of additions and repairs such as cable-stay installation,
vertical post-tensioning cables of pre-cast box substructures and concrete anchor
block repairs. He is the Engineer-of-Record for the majority of the Main Span erection
equipment and procedures, and also of post-tensioning repairs to pre-cast segments
and piers. He has knowledge of some aspects of the final structure that few persons
possess.
Clark also has had extensive direct involvement and experience in numerous other
major and complex bridge structures. In Florida alone, these include the I-595 Interchange
segmental bridges in Ft. Lauderdale, Ft. Lauderdale-Hollywood Airport/US-1 segmental
bridges, and the majority of the “drop-in Bulb Tee?or spliced pre-stressed/post-tensioned
girder bridges in the state. These bridges include the Howard Frankland Bridge,
Gandy Bridge, MacArthur Causeway Bridge, Vilano Beach Bridge, Merrill Barber Bridge,
Highland View Bridge, SR-312 Over Matanzas Inlet Bridge and the Fuller Warren Bridge.
During construction of these spliced-girder bridges, he was responsible for the
review and approval of numerous working drawing and design packages for the contractor’s
erection equipment, means and methods. As a result of this experience, he was requested
in 1999 by FDOT to perform a review of the proposed erection equipment, means and
methods for a spliced-girder bridge near St. Augustine, Florida. He prepared a report
of his review findings that resulted in major modifications to the contractor’s
proposed equipment and methods. The erection of the Main Span spliced girders was
successful for all parties involved.
During his career, Clark has served with a major pre-cast/pre-stressed concrete fabricator
and with Design/Build construction firms. He has spent substantial time in the field
with the construction and erection crews and acted as a main advisor to fabrication
and erection personnel and to clients and construction personnel during critical
phases of a project. He has performed “trouble-shooting?inspections arising from
construction variances and jobsite problems. He has performed analysis and inspection
of pile driving, structural steel and concrete beam fabrication and erection, verification
of structures under superimposed construction loading, lifting and handling methods
for component weights up to 170 tons, and erection equipment and specialized erection
procedures.
In addition, the team of Clark with Gevin J. McDaniel, P.E., SDR Structural Engineer,
was primary in designing the equipment, means and methods for erection of the new
Lee Roy Selmon Crosstown Expressway in Tampa, Florida. The project includes 5.1
miles of pre-cast concrete segmental bridges constructed using span-by-span erection
techniques. Several erection methods were required due to the complex nature of
the urban environment and construction within the median of the existing expressway.
They also assisted with the Erection Manual, erection geometry control, and other
functions in order to provide full specialty engineering services.
SDR Engineering Consultants, Inc. stands ready to serve the construction industry
with our vast resources of experience and abilities in the field of Construction
Engineering and serving as Specialty Engineer.
