Designing For Outcomes
Mike Sigman, P.E.
The new Rapid City Correctional Facility is more than a new physical plant for the South Dakota Department of Corrections. Created to address overcrowding and aging facilities, the new 102,750 square foot campus reflects a broader shift in correctional design, one that prioritizes rehabilitation, treatment, education, and family connections alongside safety and security. The goal wasn’t simply to add beds, but to create a better environment for both residents and staff.
Designed to house up to 300 women, the Level III-security campus includes three 96-bed housing units, a dedicated 12-bed mother-infant program building, inmate services and dining facilities, treatment and counseling spaces, education and workforce development areas, administration offices, and maintenance and support buildings. Together, these components create a campus that brings housing, programming, treatment, and support services together in one cohesive environment.
Like many modern public safety projects, the facility needed to balance a wide range of priorities, including security, resiliency, staff recruitment and retention, conditions of confinement, operational efficiency, and long-term flexibility. The result is a campus designed to meet today’s needs while remaining adaptable as programs, technology, and operational requirements continue to evolve.
Several specialized MEP systems contribute to the facility’s performance. High-efficiency boilers and chillers paired with variable air volume (VAV) systems provide responsive temperature control throughout the campus, while energy recovery systems help reduce heating and cooling demands. Demand-controlled ventilation using CO₂ monitoring adjusts outside air delivery based on occupancy in dining, recreation, and program spaces, supporting both energy efficiency and indoor air quality.
Life safety was another key consideration. The campus incorporates comprehensive fire sprinkler protection, advanced fire alarm systems, and engineered smoke control systems serving housing units, dining spaces, and large activity areas. Recognizing the unique challenges of correctional design, WPE partnered with a fire protection engineering specialist to develop the fire protection and smoke control strategy. Detailed airflow modeling and fire protection analysis were utilized to design the smoke evacuation and pressurization systems that support occupant safety, operational continuity, and code compliance.
The campus was also designed with resiliency in mind. A centralized emergency power system utilizing parallel generators provides redundancy and operational flexibility for critical functions during power outages. Telecommunications and technology infrastructure were integrated campus-wide to support security systems, communications, and future technology needs.
Projects like this demonstrate how public safety facilities are evolving beyond their traditional role. By bringing together secure housing, treatment, education, workforce development, and family-focused programming, the Rapid City Correctional Facility provides a modern environment designed to improve outcomes, support staff, and serve the state’s long-term correctional system objectives.
