Construction management system and construction diagram creation method

Abstract

Provided is a mechanism for creating a construction diagram from BIM information. This construction management system for a building comprises: an acquisition unit that acquires BIM information including information about a building and constituent members thereof; a selection reception unit that receives selection of a first constituent member from among the constituent members; a model information generation unit that generates construction diagram model information necessary for drawing a construction diagram model, which is a three-dimensional model for creating a construction diagram, on the basis of information relating to the first constituent member; and an output unit that outputs the generated construction diagram model information.
