Washington University School of Medicine / Barnes-Jewish Hospital Siteman Cancer Center

TW Constructors has teamed up with Clayco to erect a new 659,000-square-foot ambulatory care center for the Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine. The nine-story building will showcase a 238,560-square feet of occupied medical space and a 243,250-square-foot parking garage. The WUSM / BJH New Siteman Cancer Center will be a new landmark home for patient service, muliti-specialty cancer care, and thriving research.

Connected to the Washington University Medical Campus by a pedestrian link, the ambulatory cancer center will include 96 exam rooms; 88 infusion bays; radiology, breast imaging and chemistry laboratory departments; 430 parking spaces above the main lobby on floors two through four; and a three-bay loading dock in the lower level. This project is the latest addition to the medical campus that continues to expand in St. Louis’s Central West End. This large-scale project scheduled to open in summer 2024.
