Provided is construction management so that a final form of a structure is as designed. In the construction management, reading a design model of a structure from a design database, designing an initial construction model so that final form physical simulation results obtained by performing a physical simulation match the design model, extracting a construction completed part model, a calculating step partial physical simulation results obtained by performing the physical simulation for the construction completed part model, obtaining a measurement model from a measurement database, a calculating step an actual object difference by comparing the partial physical simulation results with the measurement model, and instructing construction details of a part to be constructed next and/or later of the initial construction model or an actual object of the structure based on the actual object difference, are performed.
