This paper reveals the detail of the construction management of the formwork of a recent complex shape building construction, Kawaguchi-shi Meguri-no Mori. In this project, the 3D-model manager (3DMr) managed the complex 3D-model of the building and revised it following many changes from the designer or the form factory. In addition, the 3DMr planned the schedule of the approval by the designer for each parts of the building, for the form factory could start the fabrication of the form on time. The management system can be effective for complex shape buildings which require more information sharing and time management.
