HMN Architects, Inc. provided full architectural services for the new Dakota County Jail in Dakota City, Nebraska.
The project was designed for two construction phases. Phase I consisted of a 34,140 square-foot-building containing 120 housing beds, 12 work release beds and jail administrative offices. The building, constructed primarily of pre-cast concrete, ties-in contextually with the 1930’s era courthouse located just east of the jail. The use of precast concrete cell modules allowed for an accelerated construction schedule and subsequent savings to the owner.
The jail and courthouse are connected to allow for secure circulation of defendants from the jail to the existing courts located on the second floor of the courthouse. Residential districts, as well as the courthouse square, bound the project site very well. To maintain the original feel of the square and uphold a sensitive outward image; avoiding a cold and oppressive feeling, care was taken throughout the design of the project.
Designed around a blended direct-indirect supervision model, the jail is a ‘three post’ facility consisting of: a centralized control station, located outside the secure perimeter of the building; booking-intake control, and a satellite housing control station. The secure central control can double as an access point for public visitors to the jail, when the office staff is unavailable to perform this function. Booking-intake control provides supervision for the work release areas and intake activities of the jail. The centralized satellite control stations are composed of a raised platform and 6-foot tall curvilinear solid surface face. Located for direct supervision of inmate housing areas the station design discourages inmate incursion, while remaining open to circulation corridors, which encourages communication between the staff and inmate population.
The jail design also includes a negative air pressure medical unit with office space for medical staff and secure storage for medications and supplies.
Phase II of the project will be a second housing area with another 120 beds and a satellite control center. The addition will lie west of Phase I, separated by the service core and the administrative offices, which are sized to accommodate expansion.
