CDC began working with a program management consultant to identify equipment that could withstand the demands of a prison. The Department created a Product Quality Committee to develop criteria for the performance, security, maintenance, and durability of equipment specifications. The consultant then conducted evaluations of certain materials and equipment (particularly food service equipment and security hardware) that focused on life-cycle costs rather than initial acquisition and allowed existing prisons to purchase replacement or retrofit equipment according to the established standards. The survey also helped CDC in conducting field inspections during construction, developing checklists for construction management firms, generating reports for equipment purchasing, and providing feedback to equipment manufacturers.
