Minnehaha County Jail Addition

Description of Project:

The Minnehaha County Jail project consisted of a vertical expansion of the existing inmate dormitory building and a 130,000 square foot addition off the East side of the building. The new addition, made up of two floors, now houses several new departments including Intake, 24/7 program, jail administration offices, judicial support, additional cell blocks, a medical clinic, and more. The addition and vertical expansion has collectively added over 300 beds to the facility.


 Phase 1: Vertical Expansion

Phase 1 was the vertical expansion of the existing jail. The expansion needed to be executed without causing disruption to the inmates and staff, so we worked on this vertical expansion without using the existing four stories of the building. Additionally, given the nature of the building usage, there were several security measures in place while the crews delivered all the equipment and materials up to the job site floor. The Olympic team worked through these challenges effectively, and this portion of the project created an additional availability of over 100 beds for Minnehaha County.

Phase 2:  East Addition

Phase 2 will add nearly 200 beds and create significant room for key resources at the Minnehaha County Jail through a sizable addition on the east side of the building. One challenge that the various teams on this project identified was maintaining high safety standards for both the crews and the public in a high traffic, downtown area. Our team ensured that vehicle traffic, pedestrian traffic, and construction traffic worked together safely and efficiently while sharing spaces. The construction of the East Addition included a full mechanical package and will house administration offices, intake, a 24/7 Program, administration offices, Master Control, Judicial Support, a medical and dental clinic, and laundry services.
