Northwestern Lake Forest Hospital Revitalization

Lake Forest, IL
With the region’s growing need for access to high-quality healthcare, the new Lake Forest Hospital is part of a 160-acre campus revitalization plan that replaces the main patient-care building with a state-of-the-art inpatient hospital and medical office building thirty miles north of Chicago. Northwestern Medicine’s Lake Forest Hospital is now home to 114 patient rooms, an emergency department, eight operating rooms, four procedure rooms, and a linear accelerator, as well as a 120,000-square-foot medical office building and facilities.

The architect designed the 493,000-square-foot project with a series of connected pavilions arranged in a crescent shape around a pond. Precast was chosen for the project due to the aggressive time frame, which enabled the contractor to efficiently enclose the building to keep the interior trades working throughout the winter. A combination of massive sunshades, as well as insulated wall panels helped the project receive LEED Silver Certification.

The project consisted of 972 precast pieces and 129,501-square-feet of wall panels on seven buildings within the complex. The main challenge was to produce brick clad architectural prestressed panels that were insulated, with multiple different concrete mixes in one panel. The 159 insulated panels were produced with nine different radiuses, convex and concave, with multiple different face mixes, while accurately keeping the insulation placed where it interfaced with the tight caulking zone requirements of the window system.
