Transit Oriented

International Spy Museum at L’Enfant Plaza

Designed by the renowned architectural firm of Rogers Stirk Harbour + Partners and local architectural firm, Hickok Cole, the International Spy Museum is a new contemporary building featuring museum exhibition, office, retail, classrooms, and event spaces, a glass atrium at the western side, a new 1st floor (exterior plaza and interior lobby and retail space), and a rooftop terrace.  The total height of the building is approximately 130 feet above the 1st floor and is adjacent to the L’Enfant Plaza Hotel.

The west side of the building is an open atrium space that cantilevers west of the property line and hangs a dramatic glass veil structure.  The atrium platforms, monumental stairs, and their supporting structural elements all consist of custom fabricated, architecturally exposed, structural steel elements.  These elements have surface preparation levels, paint, and lighting patterns that provide a dramatic showcase finish for the entire atrium. 

The building structure above the 1st floor is composed of composite steel framing with concrete-on-metal deck and steel columns.  Below the 1st floor, the existing building’s conventionally reinforced concrete structure and foundations were strengthened to accommodate the new seven-story vertical expansion.  The existing concrete columns were jacketed and new concrete shear walls were introduced in the existing building structure.  Foundations were either enlarged and/or strengthened with micropiles.

Liberty Center (Ballston Metro Station)

This 5.35 acre mixed-use development includes two office buildings, a residential tower with retail, and structured below-grade parking. Located at 675 Randolph Street in Arlington, VA, the first 13-story, 350,000 sf office building was completed in 2012 and includes a 250,000 sf structured parking garage for 600 cars that resides underneath.  The building is designed to meet Anti-Terrorism Force Protection (ATFP) standards for occupancy by a government agency.  

The 17-story residential tower was completed in 2014.  The 238,000 sf building has 256 units, 9,000 sf of retail, and a 120,000 sf structured parking garage for 272 cars. 

To be completed in 2016, the third building is an additional 20-story, 400,000 sf Class “A” office building.  Located at 4040 Wilson Boulevard, the structure will be the tallest office building in the Arlington corridor.  The development is certified at the Gold level under the LEED-ND (Neighborhood Development) pilot program.

Wisconsin Place (Friendship Heights Metro Station)

A large mixed-use, residential, retail, and commercial development at the intersection of Wisconsin and Western Avenues in Chevy Chase, MD.  The project contains a 15-story, 433-unit residential tower (480,000 sf), a new community center, a full-size Whole Foods grocery store, a 10-story office building, a new Bloomingdale’s department store, and two separate street-level retail buildings—all underlain by three levels of underground parking for 1,800 cars.  The residential tower is of post-tensioned concrete with a glass and masonry exterior.

Wisconsin Place was developed through a partnership of three national developers.  The components of the project were subdivided by a complex system of horizontal and vertical phasing lines, requiring challenging coordination between the various development and design teams.  SK&A served as the Structural Engineer of Record for the entire development.

The Corporate Office Centre at Tysons II

This massive, mixed-use complex encompasses 5.9 million square feet of commercial, residential, and retail construction in 10 high-rise buildings with structured parking for 12,000 cars. The privately-developed project accesses the Tysons Corner Metro-rail station via an elevated pedestrian bridge. Specific buildings within the development’s larger master plan include:

  • Tysons II Office Building F, PricewaterhouseCoopers Offices: Located at 1800 Tysons Boulevard, this world-class 320,000 sf, 15-story office tower was awarded the NAIOP 2005 Award of Merit for Best High-Rise Building.  The tower is dramatically elevated on five foot deep cantilever girders, supported on stainless steel bearings atop elongated columns.  Other dramatic structural features include a 36-foot long cantilevered restaurant that "floats" above the landscaped courtyard below, as well as folded concrete plate features at the roof and lower canopy levels.  A separate 275,000 sf, nine-story pre-cast concrete parking structure for 840 cars connects to Building E’s existing parking structure via elevated bridges.
  • Tysons II Office Building H: The latest installation for the Corporate Office Centre is a 17-story, 476,000 sf office building eaturing a two-story, light-filled lobby and retail center with an iconic staircase and dramatic water feature, as well as other amenities, such as a conference center, fitness center, and café. The building’s 15 floors of office space sit above the two-story glass-enclosed lobby and retail center.  The third floor, directly above the podium, is cut back to the inner column line creating a strong reveal in the building’s form and providing a large external terrace for tenants.  The scheme also incorporates a pre-cast concrete garage on 11-levels for 1,185 cars as well as a 450-foot long enclosed pedestrian sky bridge that skewers through the building lobby and connects an existing parking garage across Tysons Boulevard to the new parking structure.

The Wharf, Phase 1, SW Waterfront

Under a teaming arrangement with another structural firm, SK&A is providing structural engineering services for this multi-phased, mixed-use waterfront redevelopment, located on the historic Washington Channel adjacent to the L’Enfant Plaza and the Waterfront Metro Stations.  The master plan for the high-profile waterfront development integrates residential, office, retail, hotel and cultural facilities with numerous public spaces, including a three-acre waterfront park, along 27 acres of land overlooking the Potomac River.

SK&A is providing structural design services for three of five total parcels in Phase 1 of the project. A two-level, below-grade parking garage (782,000 sf) supports all of the parcels and is constructed over WMATA’s yellow-line tunnel.  Parcel 3 is divided into two sections: 3A includes an office building (200,000 gsf) with 20,000 gsf of ground floor retail; 3B will include a 12-story hotel (238,000 gsf) with 268 rooms, restaurants, bars, ballrooms and other meeting/event spaces, a spa, and retail space.  Parcel 4 will consist of a 12-story mixed-use residential building, evenly divided between apartments and condominiums (310,000 gsf).  A 50,000 gsf health club and 25,000 gsf of retail space will also be included in this structure.  Parcel 5 will include two hotels housed in a single building (250,000 sf).  

The Phoenix (Clarendon Metro Station)

Located one block from the Clarendon Metro station in Arlington, VA, this urban, mixed-use complex includes a 192-unit residential building, a reconstructed new post office, a three-story office building on top of the new post office, and four levels of underground parking.  The contemporary-designed project also incorporated the restoration of the existing Clarendon Post Office’s historic façade, adding architectural interest.

The 11-story residential building features over 30 floor plans ranging from studios to two bedroom apartments with dens and offers multiple amenities to its residents, such as a rooftop pool, fitness and business centers, a media screening room, library, and private courtyard.

Pike & Rose (White Flint Metro)

Built on top of the former Mid-Pike Plaza commercial site, this 28-acre urban mixed-use development is located off of Rockville Pike near to the White Flint metro.  At full build-out will include 3.4 million sf of construction, comprised of high-rise, mid-rise, low-rise, and podium structures designed by three separate architectural firms to promote distinctive designs and architectural styles.

The complex features: 1.1 million sf of office space, 1.7 million sf of residential, a 90,000 sf hotel, 430,000 sf of retail and 4,000 parking spaces.  Project phasing is programmed into twelve blocks starting with Phase 1 that features 150,000 sf of retail, an iPic theater, 490 residential units and 80,000 sf of office.
