The Three Crossings project involves the redevelopment of several urban industrial lots bordering downtown Pittsburgh along the Allegheny River. Phase I consists of the construction of 300 residential units within a five-story building overtop underground parking. Phase II consists of the construction of a 55,000-square-foot office building. Future development will consist of additional office space and a parking structure. Langan is providing site/civil, environmental, geotechnical, survey, permitting, landscape architecture, and sustainable design services for the development, which is expected to achieve LEED certification.
