Technologies of winter concreting in Russia
Knowledge and development of winter concreting technologies is necessary for building construction in Russia due to its climate conditions. This article contains an overview of the modern domestic methods of cold weather concreting. Such methods as thermos method, low temperature concrete admixture, electrode heating, heat tracing wires, electromagnetic and infrared heating, their features and advantages and disadvantages are mentioned. The technical and economic comparison, based on energy intensity and labor costs of each method indicators, is presented as well. The most suitable method is chosen. Given short recommendations for the course projects.

Manufacturability of the construction processes in trench excavations with automatic control systems
In a hard, often cramped conditions of the construction site with a high labor intensity and compressed construction time, the task of qualitative performance of excavation becomes very important. Thus, the implementation of planning works with the help of modern bulldozer requires accurate holding of the blade at design mark, which is a challenge even for experienced machine operators. Automatic control system (ACS) allows to keep working body (blade, drum mills, etc..) used by construction machines in the required design level automatically. The article offers an analysis of the technological process of the development of the construction trench for the pipeline with automatic control system Accugrade GPS / GLONASS (3D) and without ACS. Using of automated control systems AccuGrade resulted in a reduction of work time by 32%, also through unavailability of geodetic works. According to reduction of working hours excavator fuel consumption decreased by 22% and the amount of dredging material decreased by 16%, 60% less material is needed for the dumping of banquettes. Manufactural value of excavation works with ACS was 1.1

Measures to prevent fires ventilated facades
Nowadays hinged ventilated facades are actively used in reconstruction and the construction of new buildings everywhere in Russia. If a system of hinged ventilated facades is calculated and assembled correctly and the materials are properly selected, there shouldn’t be any trouble in the implementation of the system. However, a main problem of usage of the hinged ventilated facades is its fire safety. This paper presents causes and consequences of hinged ventilated facades ignition via examples of high-profile fires in former years. The risks associated with these systems in regards to fire were also analyzed. As a result, optimal technological solutions impeding ignition and spread of fire on the surface of the hinged ventilated facades were found.
