Eglin Air Force Base Bridge Replacements

Thompson Engineering served as the Engineer of Record for a Design-Build project to replace five bridges on Range Road 211 (RR211) on Eglin Air Force Base in Florida. The scope of work consisted of the design and construction of two-lane bridges to replace the existing single-lane bridges.

Thompson provided a topographic, hydraulic, and utility survey to note structural features, elevations, topography, areas of environmental concern, and roadway geometry. The survey was performed in accordance with the U.S. Army Corps of Engineers (USACE) Mobile District Design Guide, latest edition, Chapter 5, Quality Level C subsurface utility investigation, and produced in AutoCAD Civil 3D.

Planning, permitting, and engineering design was conducted that included plans for demolition of existing structures and replacement of the bridges with new precast concrete bridges meeting HS20-44 load requirements with one hundred feet (100’) of paved approach and guardrails on each end. Drainage design minimized damage to surrounding State waters and roadway integrity. Deliverables included one complete set of documents containing permits, design drawings, specifications and design analysis for the five bridges.

Individual, location-specific permitting for National Pollutant Discharge Elimination System (NPDES) was coordinated within the overall construction schedule to facilitate closure of permits for each bridge as soon as the project was complete. The design criteria utilized appropriate policy, specifications, manuals, and code published by AASHTO, FDOT, FHWA, UFC, USACE Mobile District, FDEP, EPA, ACI, ANSI, and ASTM for signage, pavements, concrete, bridge design, drainage/ hydraulics, roadways, military projects, traffic control, accessibility, and QA/QC.
