Wake County, N.C.


We provided Structural Engineering services for the Wake County Justice Center. This building, located in the hub of North Carolina’s state capital, expands over an entire city block and enhances the dynamic of Raleigh’s skyline. It was awarded LEED Silver Certification from the US Green Building Council in 2014.

The structure consists of a high-rise court tower and low-rise administrative components. The 19-story tower (12 above grade and two levels of below grade parking) has an overall building height in excess of 230 feet above grade, and houses 18 courtrooms with the potential for four additional rooms. The administrative support spaces include meeting space for the Wake County Board of Commissioners and further work space for County personnel. Our work also included below grade connections to the adjacent Wake County Public Safety Center.

The primary building construction utilizes structural steel framing with lightweight concrete slabs on metal deck. The below grade levels are structured with cast in place reinforced concrete framing. Lateral resistance is provided by structural steel braced frames (above grade) and reinforced concrete shear walls (below grade). The building is founded on augercast concrete pile foundations. Due to its proximity to an adjacent high-rise jail construction and existing deep foundations for the demolished building and parking deck, the project required a relatively complex, deep foundation design. This building was completed 6 months ahead of schedule and $30 million under budget.

We provided structural engineering services for the Durham County Justice Center. With its prominent location in the heart of downtown and right next to NC-147, the City wanted the building to have a stately and recognizable profile. The building achieved LEED Gold certification in 2013, and it has come to symbolize the civic face of the City.
