A major survey of all schools built prior to 1933 was conducted after the enactment of the Field Act, which, in California, required specific school construction standards for earthquake safety. One aspect of this study, the acoustical environment of San Francisco Schools, is described in this speech. The document outlines the following procedures: (1) for the acoustical portion of the survey, a field survey was made to establish the existing condition at the facilities; (2) deficit documentation, which involved matching the existing conditions against the district standards by computer, was then completed; (3) unit costs for corrective work on all substandard areas were developed; and (4) cost benefit tables that matched the deficit documentation with the unit costs for corrective action were established. Portions of the forms used and computer printouts are included. (Figures 1 and 6 will reproduce poorly because of marginal legibility.) (Author/MLF)
