Parking Garage

The George Washington University at 1957 E Street, NW

An 11-story, mixed-use building for The George Washington University containing both a residence hall and the Elliott School of International Affairs.  The building features below-grade parking, housing for students, office space for various academic divisions, seminar and conference facilities (including food service to support such use), and classrooms.

Within the classroom facilities, the building contains nine tiered, lecture halls on various levels, the largest of which can accommodate up to 332 people.  There are several other traditional classrooms also located in the building as well.

The structure is a poured-in-place concrete system, portions of which are post-tensioned to allow for longer spans.  The project features two 70 foot long stage-stressed transfer girders to create column-free space for the largest lecture hall.

77 H Street, NW (Walmart)

Located at First and H Streets, NW, this urban mixed-use, residential/retail urban building is designed for a Walmart store as its primary retail tenant. The project includes a two-level underground parking garage with additional street-level retail bays, the Walmart occupied anchor level, and four levels of wood-framed residences above.

The main retail entry, amenity spaces and a third floor residential pool deck above is constructed full height using poured-in-place concrete. The building also has a highly articulated façade, landscaped residential courtyards, and steel-framed, post-supported balconies.

300 New Jersey Avenue (Jones Day Headquarters)

A 10-story office building with six levels of underground parking for 458 cars. The project includes a glass canopy-covered atrium space flanked by two existing buildings (c. 1935 and 1953) and a new office wing. The new office floors have large column-free bays (42’x30’) with 11-inch thick post-tensioned concrete slabs.

The atrium canopy is supported by a segmentally-curved steel truss at the center and by adjacent buildings at the edges. The steel “tree” structure in the middle of the atrium acts as the backbone for the canopy support system, which also supports the atrium's glass elevator, seven levels of elevator lobbies and the connecting pedestrian bridges. The 100’ high x 42’ wide glass wall at the east side of atrium is hung from the 10th floor of the new building with stainless steel cables. All exposed steel members and connections conform to AESS.

The project is LEED Gold certified and was featured as the cover story in Civil Engineering magazine's May 2010 issue. The project also won the 2010 Award of Excellence for Best Urban Office over 150,000 SF from NAIOP Maryland/DC Chapter as well as the 2010 Outstanding Project Award for New Buildings $10-$50 Million from the Structural Engineers Association of Metropolitan Washington.

20 M Street, SE

This 10-story, Class “A” reinforced concrete office building with four levels of underground parking is located in the rapidly transforming Capitol Riverfront neighborhood, near the Washington Nationals baseball stadium.  Easily accessible to the Navy Yard Metro Station, the site contains office space (201,000 sf), parking (89,300 sf), a health club, and an expanded penthouse.

The building is founded on a mat foundation with a tangent pile system installed to control ground water.  The exterior design features a prominent metal rooftop canopy complemented by a smaller canopy over the entrance to the lobby.  Nine-foot high ceilings and 30-foot flat floor plates provide flexible open floor plans for tenant fit-outs.  The project ultimately received LEED Gold certification.

1000 Connecticut Avenue, NW
