Concplanner: An Automated Process Planning System for Concrete Construction

This paper presents Concplanner , a Computer Aided Process Planning system capable of generating pictorial construction process plans for automated concrete construction. Concplanner provides an efficient userinterface by adopting interactive computer graphic programming techniques. International Standards Organization computer graphic functional interface standard PHIGS has been employed to: (1) obtain graphical input through logical input devices and (2) display pictorial construction process plans. An additional capability of generating an obstacle avoidance path plan for automated concrete placement has also been incorporated into the system. The output corresponding to obstacle avoidance path plan can be used to provide equipment-level instructions to Computer Numerically Controlled concrete
