BLAST DOOR ASSEMBLIES
**************************************************************************
NOTE: The assembly paragraphs provided for
structural steel, reinforced concrete, and hollow
metal doors will be repeated and edited as many
times as required to specify all door assemblies.
The door designations will then be referenced in the
door schedule on the drawings. Items shown on the
drawings will not be duplicated in the door assembly
paragraphs. The door assembly paragraphs are
pre-edited to show normal use and hardware
availability; e.g., thermal insulation, sound
rating, and mortise locks are omitted for structural
steel and reinforced concrete doors, Type 2 hinges
are normally used for reinforced concrete doors and
thus are shown without brackets, etc.
