ATFP

This 13-story, 353,000 sf Class "A" office building is occupied by the Federal Government’s Defense Advanced Research Projects Agency (DARPA) in Arlington, VA.  The building is located within the larger Liberty Center complex, which is a 5.35-acre, mixed-use development with two office buildings, a residential tower with retail, and structured below-grade parking.  The development is certified at the Gold level under the LEED-ND (Neighborhood Development) pilot program.

Designed to meet the Department of Defense minimum Anti-Terrorism Force Protection (ATFP) standards, the building has an 82-foot secured perimeter and is surrounded by a sizeable lawn separating it from the surrounding buildings within the complex.

SK&A provided structural design services as well testing and inspection servcies, including earthwork and foundation monitoring and testing, structural concrete inspections, architectural and structural precast concrete inspections, as well as structural steel, masonry and curting wall/ windows inspections.

Located within the vibrant Arlington corridor,  The Liberty Center development is divided between Liberty Center South and Liberty Center North.  The complex features four office buildings, four residential buildings, an extended-stay Residence Inn hotel, ground level retail (70,000 sf) and structured below-grade parking.  The development is certified at the Gold level under the LEED-ND (Neighborhood Development) program. 

Major renovation and retrofit of the former Department of Transportation headquarters into a Class “A”, LEED Gold office building that exceeds GSA’s current Federal Office Building Standards and meets ISC Security Design Criteria.  Access to the subway is provided through the L’Enfant Plaza station, at D Street, SW.  The existing building was gutted down to its structure, which was salvaged and completely renovated to include replacement of the building façade and reconstruction of all service cores.

Amenity spaces were designed with a basic 30-ft. column grid to align with existing column spacing, with long-span designs considered for future tenant options.  Enhanced physical security measures exceed ISC Level IV, and include progressive collapse mitigation and blast-resistant building envelope, anti-ram barriers along the building perimeter, blast-resistant loading facilities, and common security checkpoints.

The modernized building boasts sweeping views of the city, a fitness facility, 400-seat cafeteria, and a major conference center.  The facility received Mid-Atlantic Construction’s 2010 Project of the Year Award in Renovation/Restoration.

SK&A also provided structural steel inspection; weld testing using ultrasonics for welds of the column steel jackets during construction; laboratory testing of concrete cylinders, mortar and grout tests, sprayed fireproofing testing and engineering supervision.

Mixed-use residential/commercial complex, consisting of two office buildings, two residential buildings, street level retail space, and underground parking for 1,988 cars, located at Wilson Boulevard and Quincy Street.

One Liberty Center is a 13-story, 316,000 sf office building and is 100% leased to federal government tenants.  The building is designed to meet GSA ATFP standards and is Energy Star Certified.  The Two Liberty Center office building is a nine-story, 177,000 sf office building featuring two-way post-tensioned flat plate construction with a column-free floor plan.

The development’s high-rise residential components are a 21-story apartment building (280,000 sf) with 11,000 sf of retail, and a 20-story (290,600 sf) condominium building with 9,000 sf street-level retail.  An impressive landscaped/hardscaped plaza serves the entire complex.  The entire development is served by five levels of below-grade parking totaling 750,000 sf.

This new headquarters facility for the Bureau of Public Debt, a division of the US Treasury Department, was delivered in two phases.  Phase I is a five-story building and was designed to accommodate future expansion projects and Phase II consists of a four-story building.  The building façades complement the surrounding historic architecture of the existing community through the use of brick cladding, metal paneling, and glass.

Unique structural security features include designs to meet Federal progressive collapse mitigation and blast-resistant design criteria.  The project achieved a LEED Certified rating for sustainable buildings.
