This 750,000-square-foot, half-billion-dollar expansion is organized around a 2.5-acre sustainable campus quadrangle designed in collaboration with OLIN. Sustainable attributes include rainwater harvesting, heat-reducing tree canopy, reduced stormwater runoff, and green roofs. Challenges for the project included coordination between multiple architecture firms, major utility relocations, and accommodating pedestrian and vehicular access to care facilities while construction is underway.
