Machine-readable documents in building information modeling standards

Introduction. Since 2021, adoption of building information modeling technologies has become mandatory in constructing objects using information modeling technologies. Processes of constructing buildings and structures have remained unchanged over the past two years. The time-saving effect of digitalization in construction has not been achieved, and the need to develop information models of capital construction objects resulted in additional costs for manual identification of data in the array of regulatory documents and in ignoring most of the existing requirements. Standard technical documents, even if they are written for automation purposes, do not provide for possible automated data isolation when working with them.Aim: to develop methods for translating standard technical documents into a machine-readable format based on marking up documents with codes of a building information classifier.Materials and methods. The methodology involved analyzing the schemes of documents posted on the website of the Ministry of Construction, which have been issued after the requirements on mandatory use of the classification systems in the development of building information models were included into the Town Planning Code of the Russian Federation. The analysis provided for possible unambiguous identification of data between various XML schemes of documents and the availability of a building information classifier for interfacing with the graphic part of the design documentation made in the format of the information model of the capital construction object.Results. The author proposes rules for constructing text and tabular documents with the inclusion of codes of the building information classifier for the development of XML-schemes. Allocation and markup of the tabular part serve for separating the structured and unstructured parts of the document. The marked tabular part can be exported to CAD systems and can serve a source of software settings. Tables, information about the structured coded tables, and a section of terms and definitions that are used to form the machine-readable data are subject to coding.Conclusion. Machine-readable documents can be generated both at the level of national standard technical documents and at the level of company standards reflecting the current configuration of the software adopted for capital construction projects. A set of structured tables exported from the company standards and national standard technical documents can be adopted to replace the established approach to the formation of requirements for information exchange and project implementation plans using information modeling technologies.
