This paper introduces a method for managing daily construction tasks using a text messenger and a tool to support the method. Many construction field management tools have been developed and used in practice. In addition, each company has developed its own construction task management tools. Nevertheless, due to the number of various tools available, contractors and subcontractors suffer from installing at least three or four applications on mobile devices to support different projects. To resolve this issue, the authors developed ProjectHub-CL (Construction Listener), a method and tool to manage daily construction tasks using a popular text messenger that doesn’t require the installation of an additional mobile app. It helps field engineers and subcontractors to exchange and manage field tasks using text messages and additional features on a text messenger and can automatically produce a construction daily report at the end of the day as a result. The system was implemented on top of KakaoTalk, the most popular text messenger in South Korea. Its applicability and usability in the field were validated with contractors and subcontractors in four different projects (conducted by different general contractors).
