The present invention is a computer implemented method for determining and conforming the position of fixture within a building, comprising: accessing a model; identifying a fixture and frame members, wherein the fixture are positioned within the model and interface with select frame members and have a set of properties; detecting at least one instance where the fixture interfaces with at least one of the frame members; calculating an actual location of the fixture relative to the frame members; comparing the actual location of the fixture relative to the frame members to a required location, wherein the required location is based on the set of properties and determining if the actual location is within a tolerance of the required location; and generating a list of interfaces which the actual location is outside the predetermined range of the required locations.
