With a bridge product model named NEW IFC-BRIDGE, a collaborative Augmented Reality (AR) system for the reinforcing bar design, a system showing processes of bar arrangement, and a rebar checking system using AR were developed. Both systems can superimpose virtual simulated objects on either an indoor or an outdoor environment. So engineers are able to carry out design and checking intuitively by observing real and designed reabars at the same time. Prototypes of these three systems were developed. Several indoor and on-site experiments were performed to investigate the applicability and subsequent subjects of these systems.
