Time and money were saved by reviewing security classifications and determining that there were a sufficient number of minimum-security inmates to fill a 90-cell facility, thus avoiding the extra cost of maximum-security construction. By building on the grounds of an existing institution, the cost and time of selecting a new site were avoided, as was the need to provide site security and support facilities. The use of design plans from a previous facility avoided the cost of a new design plan, and construction with precast concrete components was cheaper than conventional materials. The use of a simple rectangular design facilitated the use of prefabricated components. The design was developed using a computer-aided drafting system that accelerated and enhanced the planning process. The overall cost was less than $17,000 per inmate.
