Repairing, Retrofitting, and Maintaining Mechanical/Electrical Systems in Pre-1940 Structures

Because there are over 1 200 000 American commercial/institutional buildings erected prior to World War II, and countless more residential units, there is a need for an ordered assembly of mechanical/electrical specifications especially for these structures. In dealing with their mechanical/electrical services, it is desirable to retain the architectural integrity as well as to provide systems that satisfy both the needs of the occupants and the safety requirements of the regulatory agencies.
