We performed structural design for a 1.6-million-square-foot health care facility consisting of two sections: a children’s hospital tower that will become the new home of the Johns Hopkins Children’s Center and a Cardiovascular and Critical Care Adult Tower. The two programs were combined into a single structure to increase design and construction efficiency. The shared eight-level base will house emergency rooms, operating suites, and support facilities. To maximize utilization of a tight site, portions of the structure cantilever over roadways and existing campus structures.

The Children’s Center comprises emergency, surgical, interventional, critical and acute care departments for infants and children. The tower will also include units for high-risk obstetrics patients. The new facility will be the designated pediatric trauma center for the state of Maryland. The Cardiovascular & Critical Care Tower will provide 320 beds divided into acute care and critical care units, 20 operating rooms, an adult emergency department, endoscopy/bronchoscopy rooms, interventional labs, and a full radiology department, including MRIs and PET/CT scanners.

To accommodate the unique layout and circulation requirements of multiple departments, engineers created a bracing system that used a combination of bracing types. The design challenges posed by vibration and load requirements for sensitive medical equipment were solved through intensive collaboration with the hospital, medical equipment planners and the architectural team.

Structural CAD drawings were produced in 3-D and used during schematic design to coordinate full-depth truss and cantilever conditions with the floor plan layout and medical planning program requirements.
