Abstract
In the middle of the 20th century, technical progress allowed to maximize the size of building units, which has led to the advent of new industrial construction systems and increased construction progress rates. However, today the problem remains not completely solved and is still a vexed one. Prefabrication is not widely used, though many structural design experts predict its widespread rollout in the near future. It makes it necessary to find out the obstacles in the way of further development. The purpose of this work is to study prefabrication aspects. The objective of the study is identification of fundamental attributes common to complete modular units (the ones that include equipment and furnishings). The improvement of such aspects is meant to drastically increase design quality. The paper envelops the basic concepts of prefabrication, describes characteristics of complete modular units and analyzes the prefabrication algorithm taking into account existing BIM (Building Information Modeling) software.
Highlights
Prefabrication of engineering systems is integration of various complex standard and nonstandard assemblies with varying characteristics and parameters using a number of preselected types and standard sizes of units.A modular unit is an autonomous and ready-to-install product. [1] Modular units make up complex systems through connection, disconnection, and replacement for the purpose of creating new complexes with different components and characteristics.Prefabrication ensures fast installation, maintainability, serviceability, easy replacement of a unit without the necessity to disconnect other units.Currently it is gaining popularity in various engineering domains and industries
It is practical to represent the parameters of a complete modular unit in a three-level system that complies with the principles of modular design, and, at the same time, retains the properties of the modular element itself. (Table 1)
The modular principle utilizes a number of new features, which have a positive effect on both design and construction. Modular design includes both theoretical and practical aspects of implementation. The use of this approach implies development of new tools and ways to face new challenges, which are significantly different from the issues of traditional design

It is gaining popularity in various engineering domains and industries. Each engineering direction is at its own level of prefabrication development: it is, for instance, rather widespread in shipbuilding, but has limited application in capital construction. A great number of high-risers have been built in China with extensive application of modular units and their effective design, and construction is carried out in a very short time frame.
