施工図の実態に関する研究: 施工図の作成者と役割の変遷に着目して

摘要

我が国の建設産業では企画から竣工までの一連のプロセスにおいて多種かつ多数の図面が作成される。発注者から示される要望に対し、設計者は自らの知識•経験を活かし全体像を把握した上で設計図書の作成を行う。その後、設計図書通りの施工が行えるよう、総合建設会社や専門工事会社が施工図や製作図の作成を行う。施工図は工事の「やりよう」を示し、設計図書の詳細情報や未確定部分を補い、コストゃ工程などの生産情報を決定する上で重要な役割を果たす。%The construction drawing plays an important role in supplementing detailed information and undetermined parts of the design book and determining production information such as cost and process. As construction work was outsourced, construction managers no longer created construction drawings. Also, on the legal system, since the drawers is not defined unconditionally, the scope of the construction work and the scope of responsibility are unclear In this research, we aim to reveal the role of construction drawing by clarifying the actual conditions of construction drawing work of architect, general construction company, specialized construction company. In addition, we analyzed the transition and factors of construction outsourcing, and examined the way of construction drawing in the future.
