Up-to date criteria are presented which relate to underground heat distribution system design and evaluation. The criteria which cover systems used to convey heated fluids (usually steam or hot water at a temperature between 180 and 450 deg F) between buildings, was developed from data obtained from inspection trips, interviews with manufacturers, ahd published reports. It is recommended that in procuring such underground systems, agencies should use the systems approach wherin a single organization is assigned broad responsiblity the design, fabrication, and installation of a relatively complex assemblage of components intended to function as a unit. Responsibilities that must be assumed by the manufactureer are set forth. The responsibilities (of design organizations) and design criteria related to the definition of site conditions, the determination of the general layout and essential characteristics of the system and the reviewing of the successful bidders plans for carrying out the project are detailed. The features are desicribed of a prequalification program under which a system supplier can obtain approval to bid on agency projects. Prequalification criteria related to system performance, system application, installation, quality control, and criteria for a systmen supplier's organization are outlined. The recommendations presented here are discussed in detail.
