The application of 4D CAD in the large-scale bridge construction schedule management

Zhanfeng Song

Abstract

4D CAD is a new technology which is formed on the three dimensional CAD model adds on the new time Uygur,is recent development of CAD technology in the project construction management domain.This article has established the 4D CAD model of the large-scale bridge construction schedule management, and has developed the related system of 4D CAD on the basis of in-depth study of technology. The system can enhance the level of information management in construction managemen and provide more management information for providing the scientific and objective proof for the project management.It has a certain practical significance.
