Basic information and guidelines on the use of URBS components are provided for use by architects and engineers. The URBS system was developed in response to the competitive bidding on performance specifications, incorporating user requirements, economic constraints, industry capability and trade practices. The essence of the URBS Project--the systems approach--requires that components and materials be coordinated at their design stage so that the user requirements, production, site installation, maintenance, appearance, and cost can be considered simultaneously. There are five components in the program--(1) structure-ceiling, (2) heating-ventilating-cooling, (3) partitions, (4) bathrooms, and (5) furnishings. (TC)
