Introduction. The issue of communication of information model of structure with real building is under consideration. This matter includes damage and various impacts both inside and outside the building tracking tools and techniques. With the help of the adoption of information modeling technologies in the Russian construction industry, maintenance and reconstruction of structures will reach a new level. For this purpose, it is necessary to understand the technology of communication of the information model with the real building, which is carried out by means of nanosensors installed throughout the structure. Materials and Methods. Available research papers about integration of BIM into the process of real construction are analyzed and the urgency and necessity of development of the given industry in the modern world are proved. Results. Application of information model in reconstruction of architectural engineering sites is investigated. The technique of real model scanning of a building for the creation of information model is presented. The examples of nanosensors use for synchronization of the real construction site with its information model are given. The importance of orientation in the building using GIS and BIM communication has been established. In this review, I would like to show the importance of information modeling for Russia. Conclusions. The opportunity to combine such technologies as photogrammetry, laser scanning and ReCap software features with automated monitoring of images taken from various devices is presented. It was concluded that it is possible to integrate a single information field into the area of laser scanning and the area of combination of technologies of detection and determination of light range and BIM construction. It is proposed to combine technologies of detection and cloud access to information models with radio-frequency identifiers. Possibility of integration of three technologies is revealed: BLE-sensors, RFID-scanners and automated image monitoring in the area of BIM damage assessment after earthquakes.

Abstract. The preservation of historic buildings can often be particularly difficult due to the lack of detailed information about architectural features, construction details, etc.. However, in recent years considerable technological innovation in the field of Architecture, Engineering, and Construction (AEC) has been achieved by the Building Information Modeling (BIM) process. BIM was developed as a methodology used mainly for new construction but, given its considerable potential, this approach can also be successfully used for existing buildings, especially for buildings of historical and architectural value. In this case, it is more properly referred to as Historic – or Heritage – Building Information Modeling (HBIM). In the HBIM process, it is essential to precede the parametric modeling phase of the building with a detailed 3D survey that allows the acquisition of all geometric information. This methodology, called Scan-to-BIM, involves the use of 3D survey techniques for the production of point clouds as a geometric “database” for parametric modeling. The Scan-to-BIM approach can have several issues relating to the complexity of the survey. The work aims to apply the Scan-to-BIM approach to the survey and modeling of a historical and architectural valuable building to test a survey method, based on integrating different techniques (topography, photogrammetry and laser scanning), that improves the data acquisition phase. The “Real Cantina Borbonica” (Cellar of Royal House of Bourbon) in Partinico (Sicily, Italy) was chosen as a case study. The work has allowed achieving the HBIM of the “Real Cantina Borbonica” and testing an approach based exclusively on a topographic constraint to merge in the same reference system all the survey data (laser scanner and photogrammetric point clouds).

As engineering systems are increasingly becoming more complex, the need for information models is growing accordingly. Extensive research is currently underway to develop engineering data management capabilities and to understand the role of information as a systems integrator. In order to develop information models more effectively, a systematic methodology is needed to better manage data and develop information models. In the area of CAD/CAE/CAM applications, an information gap exists between design models and analysis models. To this end, a multi-representational architecture (MRA) is presented to facilitate the transformation of information from design models to various support analysis models. In this paper, our primary focus is on ABBs (Analysis Building Blocks) for solid mechanics and thermal systems that generate FEA (Finite Element Analysis) SMMs (Solution Method Models) to obtain their results. Our focus in this paper is to investigate the effectiveness of the Pahl and Beitz methodology in developing the ABB information model. The Pahl and Beitz design methodology is intended for physical product design applications. Three of the four phases of the Pahl and Beitz methodology are examined and modified to facilitate development of the ABB information model. The augmentations of these phases are presented in this paper. The results of the development of concepts of ABB information model using the Pahl and Beitz methodology support the use of systematic design methodologies for the development of information models. The emphasis of this work is on the methodology used to develop the ABB information model rather than the technical result of the ABB model.

Throughout the world, the intensive development of production is accompanied by a steady increase in waste generation. Ecological problems, problems of utilization and recycling of waste come to the fore. The effective functioning of the construction complex is largely determined by the effective organization of the construction and demolition waste (CDW) circulation. Considering the scale of construction, forecasting the volume of waste formation in order to effectively organize the system of economic turnover of CDW is a very relevant scientific and practical problem. Management of CDW flows in Smart cities should be based on information models containing the necessary data on the types, forms and volumes of waste. The paper presents such an information model and a mathematical method of predicting the formation of the CDW. Information modeling of the composition and volume of CDW formation allows on the basis of the developed mathematical apparatus to provide an analysis of construction development trends. It allows to carry out construction production operational and strategic planning and management in terms of the CDW formation, processing and disposal. Analysis of the construction, reconstruction and demolition CDW volume dynamics information model is the basis for further design of treatment plants future scheme.

Тhe issues of designing a multi-volume dome structure for a water park using wooden arches as load-bearing structures are сonsidered. The complexity of the volumes and their joining lines, as well as the requirement to perform non-linear analysis of large-span timber elements at the request of Eurocode 5, make an information model with elements of BIM-technology necessary. It is noted that design using this technology is developing in the direction of taking into account all stages of the structure life cycle. Wood Information modeling is the most prepared for the use of BIM-technologies. This is due to the high factory readiness and complex digital technologies for the manufacture of modern wooden structures elements. During the design, an information model was formulated in the SAPFIR software package with the subsequent possibility of importing the model into the LIRA-SAPR software package. Additional steps were used to build the model: creating a 2D template in AutoCad with reference lines and the location of rigid walls on which the coating rests, and importing drawings into SAPFIR as a dxf-underlay; for all elements of the system located in the local coordinate system, auxiliary lines were built for the correct orientation of the plane in space; loads on curved surfaces were calculated in the PC Expri. For the further development of the nodes, 3D modeling was used with the transfer of the information model to the Tekla Structures PC as a specialized environment for the constructive section of the project. The presented calculation of a complex dome structure using wooden arches summarizes the approaches to the development of unique forms of structures using wood. The use of information models made it possible to reduce the time spent on design, to optimize the drawings, and also to significantly increase the complexity of the architectural and structural design of the structure and the design model, taking into account the nonlinear effects of wood.

Building Information Models

<p><strong>Abstract.</strong> Development and implementation of information models of spatial objects affect broadest application areas currently. Building Information Models (BIMs) are now becoming extremely popular. These models are able to describe a great number characteristics of building or engineering construction, including physical and functional properties, economic parameters, visual parameters, etc. BIM use is introduced currently as the mandatory aspect of building life cycle management, from design and construction to demolition. However, implementation of the BIM concept into the reconstruction, restoration and conservation of historical and cultural heritage remains the least developed domain. Therefore, research and development activities concerned with HBIMs (Historical Building Information Models) are particularly relevant. Saint Petersburg being the second largest Russian city has a huge number of architectural monuments, while industrial architecture composes a special category of these monuments. We provided a number of research and development activities devoted to the 3D information modelling of industrial architectural monuments located in St. Petersburg. Context of these works was established by the reconstruction and adaptation of these monuments to modern needs. 3D models of buildings were produced basing on results of the laser scanning and photogrammetric survey. Basing on our work, we have formalized main approaches to design and implementation of Building Information Models of the industrial architectural monuments.</p>

Software engineers develop an information model in the systems analysis and design process to represent the concepts, specification or implementation design of a software system (Fowler and Scott, 1997). This information model is designed using a modeling language such as the Unified Modeling Language (UML) defined by Rumbaugh, Jacobson, and Booch (1999). The software is implemented by translating the information model into code. Similarly, data engineers develop an information model in the database design process to represented the types of data to be stored in a database. This conceptual information model is typically defined using one of the semantic data modeling languages (Hull and King, 1987) such as Entity-Relationship diagrams (Chen, 1976), or NIAM conceptual schemas (Leung and Nijssen, 1988). The database is implemented by translating the information model into a database schema (defined using an implementation data model such as the relational data model or an object-oriented data model). Likewise, document engineers will develop an information model when designing the structure of a collection of documents. This information model will be implemented by translating it into a document schema. Traditional database information modeling has dealt with structured data such as that found in relational databases. However, much of the information produced using and stored in computers involves documents that do not contain data with a fixed structure - rather it is referred to as semi-structured data. The need for better modeling of documents is no more apparent than in the rapid and chaotic development over the last few years of the World Wide Web. In response to this need, various information models have been proposed to model the semi-structured data found in documents.

The article presents a solution of the problem of substantiating the architecture of an interactive information model for the launch preparation of an integrated launch vehicle (ILV). The relevance of the research is due to the complexity and high dynamics of the ILV launch preparation process, as well as the latest achievements in the field of information modeling and decision support theory. The aim of the research is to raise the situational awareness of the decision maker in managing the process of preparing ILV for launch. The process of formation of situational awareness as an integral part of the decision-making process is analyzed. On the basis of this analysis a model of an indicator of the effectiveness of situational awareness formation is proposed for the first time. A model for evaluating the effectiveness of the process under study is developed on the basis of the mathematical apparatus of the theory of continuous-time Markov chains. The results of numerical experiments confirming the adequacy of the model and making it possible to state the quantitative requirements for the process of formation of situational awareness, ensuring its maximum efficiency, are presented. The tasks of the information system aimed at satisfying the requirements are stated, and the architecture of the information model of the ILV launch preparation process is developed. The research results can be used to justify the quantitative requirements for the developed information models of the launch situation at the stage of development of technical specifications.
