The construction industry is one of the important pillars of the economy. Building Information Modeling (BIM) is a set of technologies that aims to enhance collaboration across the architecture, engineering, and construction industries to improve the productivity and quality of the design, construction, and maintenance phases of a building. Rethinking construction is the key to increasing productivity. However, BIM has not been widely adopted in the construction industry. It is necessary to understand the main problems hindering the implementation of BIM, consider the appropriate strategies that can be applied to gain a deeper understanding of BIM, conduct a comprehensive and systematic analysis of the factors influencing the implementation of BIM. Based on a literature review, a questionnaire survey and the collection of statistical data, factors of a negative impact on the implementation of BIM were identified. The results show that key factors influencing BIM adoption include a lack of trained professionals, of investment in staff training, of BIM standardization, as well as the position of leadership in organizations. This article puts forward some proposals to promote the implementation of BIM and specific measures to implement the widespread use of BIM technology in the construction industry.

The method of wastewater treatment by electroflotation is based on the electrochemical process of obtaining a gas dispersion. Features of the chemical composition of wastewater affect the electrochemical processes of water decomposition and the excretion of electrolysis gases. The aim of the research was to study the regularities of the separation of electrolysis gases from the ratio of the areas of polar electrodes and the value of the active reaction of the treated water (pH). It is established that the optimum value of the ratio of the electrode areas (fa : fc) close to 1. The value of the current density at the electrodes is recommended to take in 150 – 200 A/m2. An increase in the current density leads to heating of the liquid and an over-expenditure of electricity. The greatest influence of the pH of wastewater on the process of gas excretion is noted in the acidic medium. The gas yield is independent of the pH value in neutral and alkaline media. The gas yield remains practically unchanged with a current density of more than 150 A/m2 over the entire range of pH changes from 2 to 12.
