The experiences of and approaches taken by three engineering firms using computers in their design practice are presented. The methods and procedures used by each firm to ensure reliability and professional integrity during the computer-aided design process are described. These firms represent a cross section of the profession—a small structural firm engaged in the design of highrise buildings using a microcomputer system, a medium-sized design office with 90 employees engaged in civil and structural engineering projects using a minicomputer system, and a large design firm serving the power industry with a macro-computer installation. It is the consensus of the writers that the reliability of computer-aided design is a professional responsibility and that the engineer and his firm accept this responsibility as well as the liability and risks associated with the use of computers in engineering design practice.
