DC United stadium under construction

Audi Field – DC United’s New Stadium
Washington, DC


AUDI Field, DC United’s new downtown stadium is a “state-of-the-art, world-class facility” located in Buzzard Point, Washington DC.
It features 20,000 seats with one of the steepest seating rakes in MLS (33 degrees), 31 Premium Suites in three levels, 3 Clubs, a Team Store, administrative space, and 500,000 square feet of mixed-use retail and residential space on site – all in 437,000 s.f. site; the tightest in MLS.

The structure is supported on large diameter augercast piles and grade beams.
Its unique plate girder design was developed to accommodate stringent vibration criteria and site constraints. Plate girders supporting the long canopies tapered from 140″ at the far back to 21″ at the tip.

The project featured a very aggressive design-assist / design build schedule, and opened on time on July 14, 2018.

Audi Field is one of the greenest stadiums in the US, obtaining LEED Gold certification.

John. R Thompson Jr. Intercollegiate Athletic Center
Georgetown University, Washington DC


A+F Engineers is the Structural Engineer of Record of the new John R. Thompson Intercollegiate Athletics Center for Georgetown University.

The Athletic Center is a 136,000 square feet, five-story new building that houses state-of-the-art training facilities for the university’s signature athletic programs as well as academic and administrative support centers for the university’s student athletes. The Thompson Athletic Center contains new practice courts, locker rooms, team meeting rooms, lounge areas and coaches’ offices for men’s and women’s basketball. In addition to basketball, the Thompson Center has a weight training facility for all varsity student-athletes, a student-athlete academic center, auditorium and team meeting facilities for all varsity sports programs.

The athletic training facility features vertically stacked basketball courts, which posed significant design challenges to meet the stringent vibration standards over large spans. The upper court is made of a composite slab supported by composite steel beams and steel plate girders spanning 93 feet at 32 feet on center. The plate girders are tapered at the ends to allow proper sight-lines from the second floor balconies and included web penetrations for the mechanical systems. The roof system is composed of scissor trusses.

The construction was completed in October of 2016 and the building is LEED Gold certified.
