Experience
Mr. Kennedy began his career in civil engineering in 1985. He began working at SJL in 1993 after working for two other consulting firms in Indianapolis, Indiana. Since then, Mr. Kennedy’s structural engineering experience has been primarily in bridge design work. His experience includes: bridge superstructure design (single span and continuous straight and curved cast-in-place reinforced concrete slabs; continuous and single span prestressed precast concrete I-beams and box beams; continuous and single span composite steel rolled beams and plate girders; and stress-laminated timber), bridge substructure design (integral, semi-integral, stub and conventional abutments; cap and column, capped pile, T-type and wall-type piers; spread footings on soil and rock; single and multiple-row pile supported footings and drilled shafts), foundation design (for commercial and residential buildings; retaining walls on spread and pile-supported footings; and mechanically stabilized earth [MSE] walls), bridge rehabilitation and repair, part-width design and stream hydraulics.

Bridge Design
Mr. Kennedy has been involved in the design of over 90 bridge replacement and rehabilitation projects in Indiana and Ohio. The types of work performed on these projects include: preliminary (type, size and location) design studies; detailed superstructure and substructure design; beam fatigue analysis; and bridge rating analysis using BARS-PC and AASHTO Virtis. Examples of recent projects include the following:

PIC-104-8.92, an ODOT Dist. 6 rehabilitation project featuring an existing five-span continuous reinforced concrete slab superstructure on modified semi-integral abutments and capped pile piers carrying S.R.104 over the Big Darby Creek floodway northwest of Circleville in Pickaway County.

SUM-21-2.60, an ODOT Dist. 4 rehabilitation project featuring a new 196 ft. long four-span composite metallized steel beam superstructure on existing modified abutments and piers carrying Greenwich Road over S.R.21 in Norton.

SUM-21-4.62, an ODOT Dist. 4 rehabilitation project featuring a new 200 ft. long two-span composite metallized steel beam superstructure which was converted from four spans to two on existing modified abutments and pier carrying Reimer Road over S.R.21 in Norton.

SUM-21-5.69, an ODOT Dist. 4 rehabilitation project featuring a new 216 ft. long four-span composite steel beam superstructure on existing modified abutments and piers carrying Stimson Road over S.R.21 in Copley Twp., Summit County.

SUM-21-7.78L&R, an ODOT Dist. 4 replacement project featuring new twin 82 ft. span composite steel beam bridges on semi-integral abutments supported by MSE walls carrying S.R.21 over S.R.162 west of Copley Center.

SUM-21-7.58L&R, an ODOT Dist. 4 rehabilitation project featuring rehabilitated twin 208 ft. long three-span composite steel beam bridges with skews of 52° 23’ 30” right forward carrying S.R.21 over the Wheeling and Lake Erie Railroad in Copley Twp., Summit County.

ASD-250-23.45, an ODOT Dist. 3 rehabilitation project featuring a new 130 ft. long three-span composite steel beam superstructure on modified integral abutments and piers over the Muddy Fork using part-width construction east of Rowsburg in Ashland County.

CRA-C.R.229-0.354, a county bridge replacement project featuring a 104 ft. long cast-in-place continuous concrete slab bridge on existing abutments and new drilled shaft-supported piers over the Sandusky River west of Leesville in Crawford County.

Stream Hydraulics
Mr. Kennedy has also performed hydraulic analysis and design of bridge openings (using HEC-RAS hydraulic analysis software) or culvert openings (using HY-8 culvert analysis software) for over 35 projects including several of those listed above.
