The formwork cost amounts for a significant proportion of project construction costs. It costs 10-15% of the total construction cost and 30-40% of the frame structure construction cost. In addition, the formwork collapse accidents are frequently causing deaths in the construction industry, and thus, is known to be of relatively high degree of risk. As so, the accuracy of structural calculation and quantity take-off when planning the formwork in a construction project are a very important matter. Accordingly, this study develops a BIM based formwork design prototype, that enables the construction manager to optimize the design through applying the proposed new IFC entities associated with the formwork design. The approach proposed in this study is expected to support the construction manager with accurate quantity calculation and rapid planning and construction. Since this study considered specific small-scale buildings using Euro-form and show the possibility of utilizing BIM entities in the formwork design process, further research is recommended towards the limitations in applying the system to other types of formworks.

Dewatering mold form get many holes on the surface to drain excessive water from combine concrete. While fiber is adhered to the forms inter surface, that makes it possible to improve concrete workability by draining excess water through the holes. We can expect the outer layer to solidify and to compact and get improvement of concretes durability. Maybe, it is valuable enough that dewatering mold form is put to practical use. On this study, the purpose is to obtain fundamental data for effective dewatering mold and properties of exposed concrete with the form, and ultimately, is to propose practical theory.

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.
