 Welding of the polypropylene pipes at low ambient temperatures A technique of welding into the socket in polypropylene pipes at low ambient temperatures is offered. The tests of welded socket joints made with different welding modes are carried out. It is shown that the short-term testing methods of the quality of welded joints of polymeric pipes existing in the normative documents do not reveal a violation of technological modes of welding into socket. Quality of welded joints is estimated by tests on a long stretch in the environment with surfactantt. It is established that the proposed welding technology into the socket of polypropylene pipes at low ambient temperatures provides the required level of quality produced for welded socket joints. 10.18720/CUBS.55.1 691.175.5/.8: 621.791.461 hydraulic engineering water supply polypropylene welding into the socket heating coupling pipe welded joints test on a long stretch https://unistroy.spbstu.ru/article/2017.55.1/ 1_danzanova_55.pdf

 The deviation in the calculation of the load-carrying ability of the slabs in the survey of buildings The article discusses the deviation that occurs when a non-destructive testing methods are used in the survey of buildings and structures. The errors in the calculation of the load-carrying ability of metal deck slabs, which is a consequence of this deviation are estimated, as well. Two types of slab are considered: plain and hollow. The paper surveyed the NDT methods such as: ultrasonic method, rebound hammer method, shock pulse method and surface hardness method. These methods are used to determine reinforced concrete parameters: concrete strength, steel strength, protective concrete layer, width reinforcement. The calculation was made according to the current set of rules and construction norms and regulations of Russian Federation. 10.18720/CUBS.55.2 692.522 structural survey non-destructive testing methods load-carrying ability of the floor slabs civil engineering building construction https://unistroy.spbstu.ru/article/2017.55.2/ 2_kholmin_55.pdf

 Peter the Great St. Petersburg Polytechnic University Khrestianovskaia Mariia mariachernyh@gmail.com Kukolev Maxim m_kukolev@mail.ru Primary energy sources of cogeneration units The fuel and energy complex of Russia is going through a crisis state. The main problem is the interruptions of the power supply of remote areas. One of the most promising solutions in this situation is the development of the small power for the decentralized energy supply. A cogeneration or combined heat and power systems have a great potential in the solution of this issue. In this paper, an analysis of different energy sources of cogeneration, the prime movers, is made from the point of view of the advantages and disadvantages, both technical and operational and environmental. Depending on the existing requirements, as the primary engine could be used: the reciprocating engine (or piston engine), the steam turbine, the gas turbine, fuel cell systems and the Stirling engine. In the paper there are reviewed principle of operation, size range, electrical, thermal and total efficiencies and fuels that are used for each of these cogeneration technologies. 10.18720/CUBS.55.4 69 cogeneration unit; prime mover; steam turbine; gas turbine; reciprocating engine; Stirling engine; fuel cells https://unistroy.spbstu.ru/article/2017.55.4/ 4_rodionova_55.pdf

 «Green» construction in Russia and other countries It is considered that technical progress is a basic reason of global warming. Activities of the person lead to growth of content in the atmosphere of greenhouse gases due to the increasing combustion of fuel that is the factor of increasing temperature. Climatic anomalies provoke social cataclysms. The major task at the present stage is decrease in global risks and increase in safety of people. The effective instrument of increase in sustainability is constructions of green buildings. In this article the analytical review of a modern direction of the green construction problem in Russia and in foreign countries is executed. The basic principles of a green construction, conceptual bases of buildings with low energy consumption are considered. It is specified that green roofs and green facades are important elements of ecologically steady architecture and energy-saving construction. Problems of increase in energy efficiency in case of thermorenovation of facades are considered. The principles of rating in a green construction are indicated. The received results have important practical value. Systematization and generalization of data on a green construction allow to plan further ways of increase in energy efficiency and ecological safety of buildings and structures in case of the solution of an urgent problem of increase in sustainability in town planning and architecture. 10.18720/CUBS.55.5 69 buildings construction civil engineering green constriction sustainable development energy efficiency renewable energy thermorenovation zero-energy building rating https://unistroy.spbstu.ru/article/2017.55.5/ 5_kornienko_55.pdf

 Influence of clock frequency on rendering time One of the most important factors for the successful realization of a construction project is the use of advanced software in the field of architecture. Nowadays there are many different programs for visualization. It is increasingly used to help decision-makers make economically optimal decisions. However, lack of information about interconnection of these programs and computer components leads to incorrect use of the program as well as increasing of time spent for visualization. This paper describes a method of reducing the time spent for rendering a final scene by changing the clock frequency of the computer. The data that have been obtained show changes in the rendering time after using Overclocking process for different visualization programs. 10.18720/CUBS.55.7 69 render civil engineering overclocking 3D modelling Autodesk Revit Lumion NVidia Artlantis V-ray https://unistroy.spbstu.ru/article/2017.55.7/ 7_zalata_55.pdf

 BIM-Based Quantity Takeoff Building Information Modelling (BIM) has been widely used to manage building information throughout the project life-cycle more effectively and efficiently. Particularly in quantity take-off (QTO) and estimation, BIM-based process is getting more and more attention. While BIM-based quantity takeoff is one of the potentially most important and profitable applications for BIM, it is still generally under-explored. This article is designed to explore how the information in a BIM model like the Work Breakdown Structure (WBS) and the Assembly Code for the different elements can be used to set the model effectively for extracting the quantities of elements and materials during and after the design stage by showing a case study of a residential complex in St. Petersburg city, and exploring how quantities can be extracted using the Quantification tool in Autodesk Navisworks Manage and the Schedule/Quantities tool in Autodesk Revit in association with the PivotTable tool in Microsoft Excel. 10.18720/CUBS.55.8 624 quantity takeoff (QTO) Building Information Modelling BIM classification systems Autodesk Revit Autodesk Navisworks https://unistroy.spbstu.ru/article/2017.55.8/ 8_shick_55.pdf
