DISCUSSION ON THE PROBLEM OF REGULARIZED RECONSTRUCTION IN HBIM

Abstract. In heritage recording, conservators are required to understand the subjects, that, in a sense, means to recognizing the two opposite aspects of the buildings in question: regularity and differentiation. To do a specific documentation work, one has to make balance between regularity and differentiation – the opposite poles, according to the goals and specific needs of the work. This paper discuss the goals and needs of HBIM, and regards HBIM models as “index frames” to run the information management for heritage. Therefore regularity is preferred in HBIM and the question of “regularized reconstruction” are raised. Three examples are provided to demonstrate how to realize the representation of regularity in preparing HBIM models, resulting in the conclusion: 1) partial or global regularized reconstruction is available and efficient; 2) regularized reconstruction can make best use of the advantages of BIM and bypass the disadvantages; 3) to what extent the use of regularized reconstruction depends on the regularity degree of the subject.
