Abstract

Purpose. The urbanization development in the twenty-first century is characterized by increasing the share of multifunctional infrastructure complexes among the total volume of new and renovated construction. Projects with a developed stylobate part are characterized by significant demand, as well as placing parking lots in the space of underground floors. Such solutions make it possible to effectively use the underground space while minimizing the filling of 1–5 floors. The latter requirement is typical for the construction of historic centers, where urban restrictions regulate the maximum height of the building. The research is aimed at increasing the efficiency of works provided they are combined during the arrangement of underground phase of multifunctional complexes, which are built in the historic part of cities, in a densely built-up area and extremely limited space. Methodology. The authors reviewed the world experience in the installation of multifunctional complexes and introduced best practices in organizational and technological solutions during the development of design and technological documentation for the arrangement of underground phase of the object «New construction of a multifunctional complex with parking at 25 Volodymyra Vernadskoho Street, Dnipro.» The main construction processes of the underground phase arrangement in difficult conditions of compacted construction are considered and the critical elements during their design are determined. The technological sequence of performing related works by various contractors has been improved in order to create a time reserve and increase the reliability of the entire technological process. Findings. Organizational and technological solutions have been identified that allow combining construction and installation processes of underground phase of multifunctional complexes with a significant number of subcontractors under conditions of compacted construction, as well as under complex hydrogeological conditions or during construction in the historic buildings of the central part of cities. Originality. The authors for the first time conducted research in the field of underground phase arrangement given the location of construction equipment in the limited space of the construction site in the historic part of Dnipro and proposed a number of solutions to increase the reliability of the main construction process. Practical value. Based on the results obtained, one can correct the location of construction equipment and determine the rational sequence of construction and installation works, as well as predict the further development of construction technology. These studies can be useful during the study of disciplines «Technology of Construction Production», «Technology of special works», for the organization of scientific and practical seminars, refresher courses and more.
