ABSTRACTDesign Control as applied in Detail Design is a systematic effort by a team of design engineers to concurrently arrange systems, equipment, outfit, structure, accesses, and partitions within a control area; to produce an optimum arrangement of the area involved; to assure cost—effective integration of systems; to minimize physical interferences; and to reduce installation costs. Satisfactory application of this technique insures detection and correction of most interferences early in the detail design stage before they impact production costs.This process, known as “Producibility Design Control”, has been used for the first time by NAVSEC in the Contract Design of the DDG—47. It has been applied to certain selected spaces which exhibited a potentially high density of equipment, distributive systems, high heat dissipation, and RF transmission line constraints.It is anticipated that furnishing prospective shipyards with the Navy's Contract Design for the coordination of selected areas will result in an interference—free, feasible, and producible design, and will reduce shipyard detail design man—hours.
