In this study, development of 3D software for automated formwork design was conducted to achieve optimization and reduction of labor for temporary work. Through the literature review, the current technical level was identified and the required functions of 3D software for automated formwork design were derived. The 3D software should be developed with the aim of automating 3D design, improving construction quality and utilizing the Internet of Things. As a preliminary step to develop 3D software, the prototype demo version was developed to implement 3D design automation function, which confirm the possibility of 3D software development.

Currently, a lot of design, engineering and construction companies has been interested in BIM(Building Information Modeling) technologies for higher productivity and efficiency. The information provided from BIM can be mostly used for automated quantity takeoff. But BIM has some problems for fully automated quantity takeoff to solve. The purpose of this study is to show the problems and suggest solutions through case study, especially with concrete and form work.

Recently, the interest and demand on free formed structure providing aesthetic value as well as functionality has been increasing. Formwork has numerous advantages such as high strength, convenience, accuracy and good quality of surface roughness. Nevertheless, it increases construction cost and period to build complex shapes. For these purpose, deposition construction systems such as Contour Crafting and Concrete Printing have been developed with active collaboration between university and industry by applying the rapid prototyping technology to the construction industry in USA and England. Since there has been no related research in Korea, the possibility of spin-off technology and its fusion cannot be expected. In this paper, design elements including mechanical system and control system related to automatic deposition construction system prototype for constructing a free curved structure without mold are described. As for an appropriate material for the system, fiber reinforced mortar was selected by experiments on compressive strength, fluidity, viscosity and setting time. By performing transfer and extrusion experiments, the possibility of the development of deposition construction system was demonstrated. Based on this research results, it is required to keep the automatic deposition construction system improve and extend it into the new application area in construction industry.
