McCarthy Completes Construction of New Patient Tower & Other Renovations at Mercy Hospital Jefferson


Campus expansion project includes construction of new front entrance and extensive interior renovation of existing hospital facilities.

McCarthy Building Companies, Inc. has completed construction of a new three-story, 120,000-sq.-ft. patient building on the campus of Mercy Hospital Jefferson in Crystal City, Mo.

Constructed to the south of the existing hospital facility, the $73 million tower features 90 private patient rooms and is designed to accommodate a potential vertical expansion to add new patient floors in the future.

The project also involved renovating the hospital’s main entrance to improve patient and visitor access. The new main entrance features a covered canopy, full window lantern element, reflecting pond, and stone and brick façade. Inside, patients and visitors experience improved wayfinding and new corridors that efficiently connect the emergency department, imaging, surgical services and admitting areas.

An extensive interior renovation of the existing hospital building included construction of a new emergency department waiting area and triage rooms; additional cardiology facilities; and MRI suites. Construction of a new childbirth center on the third floor of the existing tower includes new labor and delivery suites, remodeled postpartum rooms and two dedicated surgical units.

Other campus enhancements include relocation of the emergency helicopter landing pad and ambulance entrance as well as a parking expansion and repaving of Emergency Drive, which loops through the hospital property.

All construction activities progressed while the 251-bed hospital continued to provide full services to patients and the community.

“Delivering a significant construction project on an active medical campus requires constant communication with hospital staff, patients and the community,” said John Farnen, executive director of strategic projects for Mercy. “Mercy has worked with McCarthy for more than 30 years, and we rely on their healthcare expertise and ability to minimize disruptions throughout construction.”

The construction team leveraged technology, including full building information modeling (BIM) for mechanical, electrical and plumbing (MEP) coordination, to facilitate construction efficiency and accuracy.

“McCarthy values its long-term relationship with Mercy, and we were pleased to partner with them on this project to expand care to patients throughout Jefferson County and the broader community,” said McCarthy Vice President of Operations Doug Mangers.

McCarthy served as construction manager for the expansion project. Bates Architects designed the new patient tower and Heideman Associates served as MEP engineer.
