The methodology of storing the information model of building structures at various stages of the life cycle

Abstract

The paper presents an analysis of the current state of processing the results of laser scanning to build information models of construction objects at the operational stage. The authors proposed a new methodology for combining project documentation and executive (as build) documentation (obtained via laser scanning procedure), presented an application of this methodology in the context of the entire life cycle of a construction project. The authors do not try to process point clouds (laser scanning results) and convert them into BIM objects (existing approach) but offer a methodology for working with raw data as BIM object.

The importance of automating the “Construction” phase of the construction project life cycle

“…Since the end of the last decade, when works defining the stages of the building lifecycle were published [3,4], and up to now, a considerable part of such works, both domestic and foreign, has been devoted to the issues of information modeling at the pre-project and project stages of CPLC [5][6][7][8][9][10][11].The prerequisite for this was the development of industry-specific digital management decision-making support systems to meet today's demands for efficient planning, design, operation and ongoing management of construction objects. In the Russian Federation, such a system is supposed to base on the wide application of information modeling technology at all stages of the life cycle of capital construction and infrastructure objects [12].…”

Open data formats in building information modeling

“…This approach allows you to provide a sufficiently high level of detail of the project, and also makes it possible to exchange 3D models of buildings in the early stages of design to ensure the most efficient work. Throughout the life cycle of a building (LC), the information model (IM) is constantly being improved, filled with new data, going from a conceptual model to a digital analogue of a building, which, in addition to geometric information, includes temporal (4D) and cost (5D) characteristics, information about the actual the condition of the facility for maintenance during operation (6D), cost control during the life cycle of the building (7D) [1][2][3][4][5][6][7][8][9][10]. The organization of information exchange within the framework of the development of IM during various stages of the life cycle is a rather difficult task, since the historical development of software products used for the design of MI elements has led to the use of various data presentation formats for solving specialized design and calculation problems.…”

Automated identification of construction works and structural elements at an early stage of investment and construction projects’ implementation

“…The modern direction of CAD development in the construction industry is the "building information modeling" (BIM) approach, which is based on the use of a single building model and the exchange of information storage about any object by all participants throughout the life cycle of the investment and construction project [3,4,5]. Designers have and will continue to have new tools for automation of their activities [6], designing a single facility, now the best engineers distributed throughout the country can deal with it, and also, more and more often, it is practiced to attract foreign specialists.…”
