Job Description The SR400 Express Lanes Project is a transformative $4.6 billion infrastructure initiative led by SR400 Constructors, a 50/50 joint venture between Flatiron Dragados and ACCIONA. Commissioned by the Georgia Department of Transportation (GDOT) and Georgia State Road Tollway Authority (SRTA), the project will add two 16-mile express lanes from Sandy Springs MARTA Station (Exit
5) to McFarland (Exit 12), enhancing mobility along one of Georgia’s busiest corridors. With a peak workforce of over 500, the project also includes dedicated bus rapid transit stations and key bridge refurbishments. Construction is set to begin in late 2025, with substantial completion anticipated in 2031.

The Structural Engineer will provide construction-phase engineering support for bridge and structural work across the SR400 Express Lanes Project. This role will support the review of structural submittals, temporary works, construction calculations, RFIs, constructability, and field technical issues. The Structural Engineer will work closely with the Technical Director, Designer of Record, drafting team, field engineers, superintendents, quality staff, and other project disciplines to ensure structural work is safe, buildable, and compliant with project requirements.

• Provide structural engineering support to the construction team during the execution of bridge and structural works in concrete and steel.
• Review shop drawings, rebar detailing, precast and structural steel submittals, and construction methods for conformance with the design intent and project specifications.
• Design and verify temporary works (formwork, falsework, shoring, lifting plans, erection sequences) and coordinate their review and approval.
• Prepare construction-phase calculations and technical documentation, including construction staging analyses, load checks, and field change evaluations.
• Respond to RFIs and field technical queries, coordinating with the Designer of Record and the drafting team to resolve issues and implement design changes.
• Perform constructability reviews of structural design packages and propose practical, cost-effective solutions to the construction team.
• Apply relevant structural codes and standards, including AASHTO LRFD, GDOT specifications, ACI, AISC, and other applicable national and international regulations.
• Support field engineers, superintendents, and QC staff with technical guidance on construction tolerances, inspections, and non-conformance resolution.
• Participate in multidisciplinary coordination with roadway, geotechnical, drainage and construction teams, ensuring smooth interfaces between design and construction.
• Support the Technical Director with accurate analyses, technical input, and engineering solutions throughout the construction stages.
