Traditional form for concrete pouring in the slab of the girder bridge is timeconsuming and requires a lot of human resources. In addition, there are safety problems when installing and removing the forms and damage of materials, leading to an increase in cost. SMART from Purlin support system developed to solve these problems is to install support in the upper flange of the girder to support the forms of the slab. However, the complicated support structure of forms resulted in various problems, including increased production and transport costs and decreased use on-site owing to the lifting method. To supplement such problems, the SMART form Purlin hanging system was developed. This study aims to develop a form system for concrete pouring in the slab of the girder bridge. In addition, it is to check whether the formwork cost is reduced when the SMART form purlin hanging system is adopted through a cost analysis by comparing with the traditional form.
