Buildings life cycle methodology aspects
The term "life cycle" passed from scientific studies to the construction industry official professional discourse in relation to buildings and structures about 10 years ago. However, the use of this term in regulatory documents, as well as in public media, has a number of features that should be analyzed in order to avoid negative effects in further methodological developments in the field of information modeling in construction. This article discusses the methodological aspects of the life cycle of buildings and structures from the standpoint of epistemology and ontology. The author reveals the opposition of the terms "life line" and "life cycle" of a technical product, the relationship of the terms "information model" and "life cycle" in the construction sector. The article provides an overview of the regulations in the field of information modeling in construction, which contains the above-mentioned terminology. The subject of the study is a life cycle model for buildings and structures, including differences in the meanings of terms in the general technical and construction spheres. The author focuses on the processes that turn the life line of a technical product into the life cycle of an technology object. It is concluded that the life cycle is defined not for examples, but for categories of technical objects through their information models. The author offers an infographic model of the life cycle of buildings and structures, as well as his definition of the life cycle for buildings and structures. The author suggests that the life cycle of buildings and structures exists in a technogenic environment, being a variant of technocenosis, and it is characterized by at least three conditions.
