 Integrated efficiency assessment of road reconditioning The paper dwells on the issues of improving traffic quality and safety; analyses domestic and foreign experience of road reconditioning by applying modern methods. It assessed the operating usefulness of modern repair methods (depending on the condition of road pavement before repair). The minimum warranty service life of pavements was established by analytic and experimental way after applying the relevant method of repair. The algorithm of operational and economic feasibility of repair work is designed and grounded on the basis of domestic and foreign methods of quality assessment of repairs. The proposed method considers not only condition of pavement before repair and cost of repairs but also effects of improving traffic quality and safety and prolonging road service life. The method also considers climatic conditions of regions that allows more reliably to predict operational efficiency of repair work. The main feature of this method is ability at a stage of substantiation of engineering and technical decisions to predict operational and economic benefits of using one or another option of roadwork and on the basis of economic-mathematical modelling to show which option will be more expedient and efficient. 10.18720/CUBS.58.1 69 road repair covering road pavement efficiency repairs economic-mathematical assessment https://unistroy.spbstu.ru/article/2017.58.1/ 01_kamenchukov_58.pdf

 Simulation modeling of winter concreting of wall construction There are many technologies of winter concreting, both in domestic and foreign practice. With a large selection of options for warming concrete, used for various design systems and environmental conditions, the method of heating by wires is currently the most common. Analysis of modern methods of heat treatment of concrete shows that the use of heating wires allows the supply of heat directly to concrete in the required volume at each stage of its maintenance. This helps to optimize the process of electric heating, and also affects the rate of temperature rise and cooling of concrete. In this paper, modeling is considered with the use of modern software-computational complexes capable of solving the problem of heating concrete at the stages of its aging. One of the complexes designed to solve such problems by the finite element method is the ELCUT software package. It, together with the WinConcret add-in, is able to calculate temperature fields, build a timetable for the strength of concrete and calculate the temperature deformation from the heating of building structures. In the framework of the work, modeling of the problem of warming concrete of a monolithic wall with a heating wire was carried out. The problem of the distribution of temperature fields over the section of the monolithic wall structure and the strength of concrete has been solved. In order to accelerate the hardening of concrete, it is suggested to use, for example, a quick-setting cement or a heating casing 10.18720/CUBS.58.2 69 concrete mix thick-reinforced construction wall construction winter concreting heating wires ELCUT program thermodynamic task concrete heating https://unistroy.spbstu.ru/article/2017.58.2/ 02_komarinskiy_58.pdf

 Technology of wood impregnation by polymeric compositions The problem of efficiency of application of special means of improving the quality of impregnation, modification and preservation of wood is extremely important in Russian economy. Economic and environmental efficiency of wood treatment with the aim of increasing its structural and finishing properties is quite obvious, but at the moment there is no single methodology for determining it for different types of impregnating polymeric composite materials and for the method of impregnation. The aim of this study is a detailed analysis of traditional and perspective methods of impregnation, preservation and modification of wood using different types of polymer composite materials, and identifying the most effective methods. The study gives a list of the main methods and means of wood protection, all groups of pests harmful to wood, and forms a list of technologies for the impregnation of wood using different physical peculiarities of the process and equipment according to the critical analysis of the technological equipment of the impregnation plants. One of the important results of the study is identifying criteria for the quality of impregnation of wood and recommendations on labor protection in enterprises, with consideration of environmental aspect. According to the results of the study the following conclusions were formulated. At first, it is extremely advisable to optimize parameters of deep impregnation of the wood with the use of basic available technologies. Second point is that at this time the most promising methods of wood treatment are autoclave method using a vacuum and high pressure, and the method of exposure to wood ultrasonic electromagnetic waves. Finally, the technology ultrasonic industrial impregnations is still not developed, there is no technological scheme and necessary equipment. 10.18720/CUBS.58.3 69 wood lumber impregnation polymer compositions construction buildings civil engineering https://unistroy.spbstu.ru/article/2017.58.3/ 03_chernenko_58.pdf

 Substantiation of efficient use of land plots situated in the historical center of Saint Petersburg The aim of the article is to find and substantiate an efficient use of unoccupied land plots in the central districts of Saint Petersburg. Three sectors of the city center were investigated and the most appropriate type of functional building assignment was chosen for the land. For this purpose in the research there was an analysis of the location of the chosen sectors, the experience of using the land of demolished buildings, the real estate market of the districts on which the land plots are located, also there was an interview of citizens for evaluating the potential exploitation of the sectors on certain criteria. According to the results, an art-development center got maximum rating but because of the economic reason – little space payback, building of the center is beside the purpose. The second place was given to a sports center but as one is currently situated not far from the investigated territories building of this structure is unprofitable. The third rating was for an overground parking which is very essential in the center of the city. As the social and economic significance of the parking are very high this object is the most favorable for building on the unoccupied territory. Efficient use of the land plot by choosing this object to be built in the central part of Saint Petersburg is confirmed by analyzed factors and results of the interview. 10.18720/CUBS.58.5 69 historical center civil engineering buildings land plot efficiency assessment interview city center substantiation efficient use functional assignment https://unistroy.spbstu.ru/article/2017.58.5/ 05_kuz'mina_58.pdf

 Normative bases of labor costs influence on construction duration and crew forming The paper considers the scheduling of construction of four objects using three different normative bases: Unified Norms and Prices (further – UN&P, Russia), KI “Rakennustöiden laatu RTL” (further – RATU, Finland), “Building Construction Costs with RSMeans Data” (further – RSMeans, United States of America, USA). An integrated approach to the calculation of amounts of works for each object, labour hours, the number of labours in the construction crew, allowed to reveal fundamental differences in terms of the building and its resource providing. The conducted research gives an opportunity to objectively assess the applicability of certain standards in today's construction market. According to the results of researches it was found that the smallest duration of construction is achieved by applying a normative base RSMeans (USA). The maximum duration of construction is obtained with the use of a domestic normative base. These conclusions indicate the necessity of modernization of the national normative base in building and possible integration of foreign one for the most effective scheduling of construction within the set terms and with necessary level of quality. 10.18720/CUBS.58.6 69 здания; строительство; гражданское строительство; продолжительность строительства; планирование; основы нормативных затрат на оплату труда; трудозатраты работ; строительная бригада; https://unistroy.spbstu.ru/article/2017.58.6/ 06_romanovich_58.pdf
