Complete Survey Before Demolition

A survey to identify the presence and location of asbestos containing materials must be completed prior to demolition. In the absence of a survey or if one cannot safely be performed, all surfacing materials and thermal system insulation in building constructed no later than 1980 must be presumed to contain asbestos (demolition of surfacing materials and thermal system insulation presumed to be asbestos containing is Class I asbestos work).
