Interdisciplinary Design and Construction of a World-Class Waterfront Development

Register by Friday, May 19. To register, click here.

The Wharf Phase II in Washington, DC's Southwest Waterfront district is a highly anticipated addition to one of the district's most popular neighborhoods to live, work, eat, shop and visit. Phase 2 completes a mile-long waterfront experience with the addition of over 1.15 million square feet of mixed-use space, including a marina, office, residential, retail as well as parks and public spaces. The Wharf has been described as one of the most significant and successful urban waterfront developments in the world.

Members of the interdisciplinary design team for The Wharf Phase 2 will share a brief overview of the challenges and solutions throughout the design and construction process. The panel presentation will feature Jason Abbey of Perkins Eastman DC, the master planner and master architect of The Wharf, Nima Arjomandnia of SK&A, the structural engineer of record for Garage 2 and parcels 6&7, Henry Clouting of Thornton Tomasetti, the structural engineer of record of Garage 3, and Aaron Sacks of Mueser Rutledge Consulting Engineers, geotechnical engineer and support-of-excavation designer for the garages over and adjacent to the WMATA tunnels. The project team will discuss the unique challenges presented by the program and the site conditions related to the below-grade parking garage located directly adjacent to the Washington Channel, in close proximity to active subway tunnels, and below multiple buildings. Following the discussion, the team will reflect on the collaborative solutions developed in response to these challenges to make this project a success.

All parking on the site is contained in a two- to three-story below-grade parking garage and is protected from the Washington Channel by a new seawall that extends to depth up to 85 ft into the channel. The garage was designed to accommodate multiple existing systems on the site, including an existing 108-in diameter DC Water pipe that bifurcates the site, as well as two decades-old Washington Metropolitan Area Transit Authority (WMATA) tunnels that curve through the site. Design and construction of the parking garage directly relates to the challenges presented by these existing systems, and influenced the design of the towers located above.

Welcome to the website of the National Capital Section of the American Society of Civil Engineers (ASCE), a professional society for civil engineers.  ASCE was founded in 1852, represents 130,000 members of the civil engineering professional worldwide, and is America's oldest national engineering society.

The National Capital Section was founded in 1916 and currently has more than 3,100 members.  The section is located in Region 2 (link to region 2: The National Capital Section serves the District of Columbia; the counties of Montgomery and Prince Georges in Maryland, except College Park in Prince Georges County; the counties of Fairfax and Arlington, and City of Alexandria in Virginia. The National Capital Section's mission includes:

  • To advance the professional knowledge and improve the practice of civil engineering for our members and those we serve.
  • To advocate for our profession with those whose actions affect us, and to educate those whose actions and responsibilities could benefit from a better understanding of the contributions of civil engineers.
  • To improve our community through effective community outreach programs, local involvement and educational efforts.
