The paper is based on a review of the scientific publications released from May through October 2019, the greater part of which, namely 14 papers, is included in the Web of Science scientometric database. The authors of the papers analyzed explore the construction industry problems over the past 5 years. The foreign studies listed in the reference section were based on the analysis of reviews falling in the above-mentioned timeline. The purpose of this paper is to identify the problems hindering the implementation of BIM technologies in the construction sector, not only in the foreign countries, but also in Russia.

The paper focuses on energy efficient reconstruction of construction systems by means of their upward extension using modular spatial structures. It is further noted that the existing contradictory definition of the term “modular structures” necessitates classifying modular structural elements by spatial dimension, type and size, weight, degree of prefabrication, constructability and environmental safety. A list of the world’s leading manufacturers is provided featuring modular spatial structures to be used in the construction of new buildings and reconstruction of existing buildings. Also, the paper underlines the importance of using added stories in making modular roof structures of lightweight metallic structures (LMS) and lightweight thin-wall steel structures (LTSS) and provides an overview of the main types of modules, pointing out the key benefits of modular structures.
