Construction Owners Editorial Team

Highlights

  • The replacement FCI Leavenworth project has achieved LEED Silver certification.
  • The $532 million design-build project covers a 200-acre federal correctional campus.
  • The development includes 23 buildings totaling about 630,000 square feet.
  • The campus is planned to accommodate about 1,500 inmates and 340 staff members.
  • Clark Construction is leading the design-build effort with Elevatus Architecture.

The certification adds a sustainability milestone to a major federal correctional replacement project, highlighting how energy, water and resource-efficiency requirements are being incorporated into large secure facilities. The $532 million replacement for the aging FCI Leavenworth in Kansas is being developed as a modern correctional campus with dedicated spaces for security, operations, training and rehabilitation.

Campus Scale and Construction Program

The new FCI Leavenworth campus will occupy approximately 200 acres and contain 23 buildings with a combined area of about 630,000 square feet. Clark Construction is delivering the project through a design-build approach, with Elevatus Architecture serving as the architectural partner.

The completed campus is planned to include a 1,152-bed medium-security institution and a 256-bed minimum-security camp. Approximately 340 staff members are expected to support operations.

The project replaces the existing federal penitentiary, which dates to 1897. The replacement program addresses the aging facility's infrastructure while providing updated spaces for contemporary correctional operations.

Program areas include education, treatment, job training and family-connection functions. The new administration building also incorporates design elements associated with the historic facility, including references to its stone façade and dome.

LEED Certification Adds Sustainability Requirements

LEED Silver certification recognizes sustainability measures incorporated into the campus, including high-performance mechanical systems, water-efficiency strategies and durable material selections.

For correctional facility owners, sustainability requirements can add complexity to projects because energy, water and building-performance objectives must be coordinated with stringent security and operational requirements.

The project is scheduled for completion in 2026, when the new campus will replace the existing facility and provide updated infrastructure for federal correctional operations.

Why It Matters

The FCI Leavenworth replacement demonstrates the scale and specialized coordination involved in modern federal correctional construction. The combination of secure environments, rehabilitation programming and LEED-certified building systems requires project teams to integrate operational, security and sustainability requirements throughout design and construction.
