OSF/Children’s Hospital of Illinois

Peoria, Illinois / United States of America

OSF Saint Francis Medical Center is home to the Children’s Hospital of Illinois (CHOI), a “hospital within a hospital” providing the only comprehensive pediatric specialty and subspecialty services in central IllinoisThe Project consists of a $234 million, 440,000 sf addition to the medical center, a 35,000 sf renovation, site development, and infrastructure improvements. The project creates a new front door to the campus reorienting traffic from an underbuilding entry to an open and inviting entry sequence. It is highly visible from the adjacent expressway and its framed rectangles of color evoke children’s blocks giving a nod to the Children’s hospital component of the project without overwhelming the presence of the main hospital. The addition consolidates CHOI inpatient services, including PICU (24,000 gsf), NICU (34,000 gsf), and general pediatrics, and also houses various adult services, such as relocated emergency and surgery departments, inpatient beds, ICU, vascular and catheterization labs, a main entrance and lobby, and other support and public functions. The 47,000 sf emergency department is both the area’s only level 1 trauma center and a regional hub for disaster responses. It is an “all-risks ready” emergency department with built-in capability to manage the medical consequences of terrorism, disasters, and epidemics.
