A version of the project for the installation of the spatial structure of the coating of an industrial building was developed. The technological feature of the project was the presence of cramped working conditions. The feasibility study of the methods of assembly and installation of the coating, taking into account the peculiarities of the construction of the coating, the features of the construction site and the needs for lifting machines, showed the eff ectiveness of the installation of the coating with enlarged blocks assembled on the ground. Mounting the unit using a traverse allowed to reduce the estimated height of the hook and select a crane that does not diff er in the high cost of rent. It became possible to apply the adopted installation scheme provided that an individual design of the beam was developed. The calculation and design of the traverse itself was performed, as well as the calculation of the enlarged unit for the installation situation.

The article presents information on the development of a new technical solution for the spatially-barrel construction of the covering. The authors propose a metal three-dimensional lattice construction, assembled from corner sections using sheet shapes in knots. On the proposed solution the authors obtained a patent. To prove the validity of the previously stated assumptions about the properties of the future design, namely its reliability and safety, the authors carried out experimental design work. The proposed coating design was designed, manufactured and applied as a covering for a production building. After the installation of the roof experimental design tests were carried out by design load. The load was simulated by loading the cover with sandbags. During the tests the stresses were measured in the most important rods. The results of the measurements showed compliance with the calculated forecasts.

Technological Methods

Dangerous and harmful production factors are considered, the impact of which is experienced by workers during the construction of any facility. Analyzed: the reasons for the formation of these factors for various types of work; equipment, structures and materials, the impact of which on working personnel can also lead to adverse situations. It is noted that the means of individual protection must be selected, paying attention to what kind of work will be performed by the employee and under what conditions. The most effective personal protective equipment and technological methods for improving working conditions at the facility are proposed for use by the workers of the object under consideration. The results obtained can be used to improve the working conditions of workers in warehouses with raw materials.

The geological structure, hydrogeological conditions were evaluated and the main indicators of the engineering and geological properties of the base soils at the construction site of the federal highway were determined. The designed section of the road crosses the existing field roads. To pass field roads, an artificial construction device is required. A feasibility study of three options for the construction of a reinforced concrete culvert, a single-span overpass and a two-span tunnel type overpass has been completed. The advantages and disadvantages of each of the considered options for structures are analyzed. As a recommended option, a monolithic reinforced concrete pipe device is provided. The corresponding conclusions and recommendations are given.

Rapid growth in the construction industry has increased construction waste generation and caused serious impact on the environment. In Malaysia, most contractors are using the conventional method as the main method in the construction process. However, using conventional methods for construction work is not environmentally friendly because of the poor quality control at the construction site and the uncontrolled waste production. This has contributed to pollution problems in the environment in the form of air and water pollution, and construction waste. The aim of this study was to identify the type of construction waste and causes of waste generation from conventional methods with IBS. In addition, this study also suggests measures to minimize construction waste generation at the construction site. This study used quantitative methods of questionnaires as an instrument. A total of 200 questionnaires were distributed to the G7 contractors and developers in Johor to get feedback. The data obtained were analyzed using statistical methods and indices mean. From the results, it was found that most types of solid waste high in conventional construction are wood (3.85) but with the use of IBS, wood waste generation can be reduced (3.15). For the source of waste generation, it shows that the handling process is the main cause with the mean score (3.47) in IBS and the mean score (3.75) during construction is carried out for conventional methods. Therefore, IBS technology is the considered best option in order to minimize waste generation at the construction site.

High-resolution 21-cm line observations in a region aroundlII= 120°,b11= +15°, have revealed four types of structure in the interstellar hydrogen: a smooth background, large sheets of density 2 atoms cm-3, clouds occurring mostly in groups, and ‘Cloudlets’ of a few solar masses and a few parsecs in size; the velocity dispersion in the Cloudlets is only 1 km/sec. Strong temperature variations in the gas are in evidence.
