Framework for development of CAD/CAC systems

Abstract This paper provides a framework for the development of Computer-Aided-Design/Computer-Aided-Construction (CAD/CAC) systems. A description of the proposed CAD/CAC systems is provided. The proposed system contains software tools related to (1) conceptual design, (2) structural and foundation analysis, (3) design of structural components, (4) routine geometric, mathematical, and optimization functions, (5) construction management, (6) Computer Aided Process Planning (CAPP), (7) process simulation, and (8) constructability analysis. On-going research work in areas related to CAD/CAC systems are highlighted. Incorporation of Group Technology (GT) paradigm for civil engineering structures to enhance the efficiency and effectiveness of the proposed systems is investigated. Issues related to algorithm development are also discussed. Possible extension of Automatically Programmed Tools (APT) language to include construction industry processes are examined. Specifically, the programming level syntax of APT can be extended by adding construction related vocabulary and features to only two out of five statement types and processor-level syntax can be extended by incorporating additional modular features.
