ECU Main Campus Student Center

As part of an overall effort by East Carolina University to enhance campus appearance and student engagement, ECU began preparations for a new $122.2-million student center and adjacent parking garage which opened in 2019. In addition to the construction of the 210,000-sq-ft student center, the project involved a 40,400-sq-ft basement area, a 426,000-sq-ft parking deck, and a 17,000-sq-ft lower level.

Morrison Engineers was engaged to design and construct a temporary excavation shoring system to facilitate the excavation and construction of the lower level of the new student center and parking deck. This system evolved from a complete soil nail shoring system of 8,500 square feet into a combination of temporary soil nails with a flexible facing, soil nails with supplemental hollow bar ground anchors, and anchored soldier piles with timber lagging, for a total shored area of 11,000 square feet and over 35,000 linear feet of soil nails and tieback anchors.
