Bridge Design

Bridge Engineer, Toll 49 Design Build, Tyler, Texas, North East Texas Regional Mobility Authority, 2011.
Prepared independent structural calculations in a very compressed time-frame for five separate bridges on this design build project. Calculations were performed to independently verify the design of the proposed bridges, and included the LRFD design of the concrete deck, expansion joints, prestressed concrete I-girders, elastomeric bearing pads, and multi-column frame bents and abutments which included an LPILE lateral analysis of the drilled shafts.

Bridge Engineer, IH 35 Improvement, Temple, Texas, Texas DOT, 2010-2011.
Bridge Engineer for the final design of a 450-foot and 670-foot multi-span frontage road bridge over the BNSF railroad. These bridges are on a curved and superelevated alignment, and utilize straight prestressed tub and I-girder segments. Responsibilities included the LRFD final design of the single column bents (T-piers), which featured cantilevers of up to 18 feet and were supported on a single 66-inch diameter drilled shaft. Also responsible for the design review of the two 1740-foot IH 35 mainline bridges, which were also on a curved alignment in a superelevation transition.

Bridge Engineer, Route 364 (Page Avenue Extension), St. Charles County, Missouri, Missouri DOT, 2009.
Bridge Engineer for the LRFD final design of the prestressed concrete NU girders of three separate bridges on this $48 million corridor extension project. Responsibilities also included custom structural design of the bridge mounted signs.

Hydraulic Engineer, IA 100 Cedar River Bridge, Linn County, Iowa, Iowa DOT, 2007-2011.
Performed HEC-RAS hydraulic modeling and scour analysis for this 1880-foot curved Welded Plate Girder Bridge in a Flood Insurance Study area over the Cedar River. A detailed hydraulic report was also completed for this complex crossing, including permit applications to the Iowa DNR and US Army Corps of Engineers.

Bridge Engineer, I-80 / I-29 Interstate System, Council Bluffs, Iowa, Iowa DOT, 2006-2008.
Project Engineer for the preliminary design of 18 bridges in Segment 3 of the East System Interchange of the I-80 / I-29 corridor through Council Bluffs. Bridge types range from relatively short grade separations and stream crossings, to complex viaducts and curved flyover ramps over 3000 feet in length. Preliminary design duties also included HEC-RAS hydraulic modeling and completion of a detailed hydraulic report for a critical stream crossing in a Flood Insurance Study area.

Bridge Engineer, Broadway Viaduct, Council Bluffs, Iowa, Iowa DOT, 2006-2008.
Developed an in-depth structure type study as part of the preliminary design of this large viaduct to aid the Iowa DOT in selection of the preferred bridge alternative. Numerous superstructure, substructure, foundation, and approach types were reviewed, with consideration for accelerated construction techniques. Detailed construction cost estimates and schedules were provided as part of the study.

Bridge Engineer, Arugam Bay Bridges Replacement Project, Sri Lanka Tsunami Reconstruction Program, United States Agency for International Development (USAID), 2006-2007.
Performed detailed design of the precast deck panels and steel girder splices for two rolled steel girder bridges (160 m and 25 m in length) over the Arugam Bay that were replaced due to damage caused by the 2004 Tsunami that hit the south and east coasts of Sri Lanka. Also completed a detailed shop drawing review for the precast deck panels and substructures.

Bridge Engineer, Wilson Street Culvert, City of Van Meter, Iowa, 2005.
Project Engineer for the preliminary design of a reinforced concrete box culvert to replace a deteriorated single-span bridge. Hydraulic analysis of this triple box culvert, along with permit applications to the Iowa DNR and US Army Corps of Engineers were completed as part of the preliminary design.

Bridge Engineer, F36 over Indian Creek, Jasper County, Iowa, 2004-2005.
Project Engineer for the preliminary and final design of a custom 233-foot, three-span prestressed beam bridge with a roadway width of 30 feet. Preliminary design included a hydraulic analysis to determine the required bridge opening. A wave-equation analysis was also completed to aid in steel pile driving during construction.

Bridge Engineer, 495^th Street over Little Sioux River, Clay County, Iowa, 2004.
Preliminary and final design of a custom 263-foot, three span prestressed beam bridge. A hydraulic analysis of this 24-foot wide bridge was completed as part of the preliminary design. The bridge consists of a reinforced concrete deck on prestressed concrete beams, reinforced concrete hammerhead piers and integral abutments.

Bridge Engineer, South 12^th Avenue over North Skunk River, Jasper County, Iowa, 2003-2004.
Project Engineer for the preliminary and final design of a custom 272-foot, two span prestressed beam bridge over the North Skunk River. This highly skewed river crossing required the use of a single hammerhead pier in the center of the North Skunk River to avoid existing foundations. Prestressed bulb-tee beam sections were used to accomplish the two 136-foot spans. A wave-equation analysis for the steel piling was also performed as part of the construction services.

Bridge Engineer, I-35 over UPRR, Iowa DOT, 2001-2002.
Participated in the final design of these custom dual prestressed concrete bridges over the UPRR in Ankeny, Iowa. These bridges are on a curved alignment, with a high skew and superelevation. Straight prestressed concrete beam segments, and flared beam lines were utilized to mimic the horizontal curvature of the superstructure to maximize economy and constructability.

Bridge Engineer, 4^th Street over Clear Creek, Lansing, Iowa, 2001.
Project Engineer for the final design of a three-span continuous concrete slab bridge. This custom bridge utilized reinforced concrete wall piers, and included concrete open rails and a sidewalk on one side of the bridge.
