Target costs for the University Residential Building System (URBS) Project of the University of California are presented. Findings depict the effectiveness of building design and material applications and should be useful in guiding future student housing design work, whether the design utilizes the URBS system or not. Ten recently constructed single-student residence halls on seven of the nine campuses of the University of California were selected for analysis. These buildings were grouped by types of construction as defined in the Uniform Building Code. Only residential areas, including related study rooms, lounges, toilet rooms, lobbies, and public circulation areas were included in the study. Costs as stated include only those required for construction of the residence hall building itself. The study method was to estimate the cost of buildings from the working drawings, specifications and change orders as if each project were bid for construction in the San Francisco Bay Area in January 1966.
