The main methods of construction of the underground part of buildings are given. It is shown that the choice of the method requires a mandatory technical and economic comparison of various options, since different construction methods can be used for almost any structural scheme of the underground part and under any hydrogeological conditions. An important role in choosing a method is to assess its reliability - ensuring compliance with all design parameters, as well as the integrity of buildings located in the zone of influence. The most serious justification requires the method "Top Down" (top-down), the use of which for some conditions leads to cheaper, but in most cases - to a significant increase in the cost of construction. For comparative analysis, a survey of several objects under construction in Moscow was performed and the design documentation of previously constructed objects using the "Top Down" method was studied. The performed approximate calculations showed that the use of this method leads, as a rule, to a significant increase in the cost of construction of the underground part.

<p>The effect of a dual tire pressure on the design parameters of thick asphalt pavements using finite element freeware EverStressFE©1.0 is evaluated. This is trying to represent more adjusted the footprint shape and intensity of stress generated by the tires of vehicles. To validate the elastic multilayer EverStress©5.0 software was used. The results of the deformations can be concluded that the asphalt pavement designs made with analytical methods may be slightly oversized and consequently increase the cost of construction of pavements. This study marks a route to analyze the sensitivity of various factors that may affect the design of asphalt pavements. Future research is expected to integrate dynamic conditions by introducing results of field tests to full scale.</p>

The problems of definition of the cost of design in construction are considered in the article. The existing regulatory documentation for determining the value of construction products on the territory of the Russian Federation is analyzed. A comparative analysis of the currently used methods for calculating the cost of designing is executed. The advantages and disadvantages of each method are considered, and the necessity of transformations in the sphere of determining the cost of design works is substantiated. The ways of increasing accuracy of calculation of the cost of design in construction are suggested, including the use of the territorial coefficient in calculations when utilizing the method of dependence on the natural indicators of the design objects. It is revealed that the use of this coefficient significantly increases the accuracy of calculations. For the method of calculating the cost of design as a percentage of the total cost of construction, it is proposed to clarify the methodology for calculating the cost of construction of multi-apartment buildings according to the enlarged construction price standards. It is proved that today it is impossible to replace the value of individual structural elements of an object in the event of differences in the design solutions with the solutions represented by similar objects in the collection of the construction price standards. The ways of solving these issues by the use of collections of standards for the price of construction solutions are outlined. The authors are convinced that the improvement of methods for calculating the cost of design products will improve the efficiency of investments in the construction industry.

The second part of the translation has three segments. The first is dedicated to the history of Delhi from the time of the Mahabharat to the periods of Anangpal Tomar to the Mughal Emperor Humayun as also Sher Shah, the Afghan ruler. In the second and third segments Mirza Sangin Beg adroitly navigates between twin centres of power in the city. He writes about Qila Mubarak, or the Red Fort, and gives an account of the several buildings inside it and the cost of construction of the same. He ambles into the precincts and mentions the buildings constructed by Shahjahan and other rulers, associating them with some specific inmates of the fort and the functions performed within them. When the author takes a walk in the city of Shahjahanabad, he writes of numerous residents, habitations of rich, poor, and ordinary people, their mansions and localities, general and specialized bazars, the in different skills practised areas, places of worship and revelry, processions exemplifying popular culture and local traditions, and institutions that had a resonance in other cultures. The Berlin manuscript gives generous details of the officials of the English East India Company, both native and foreign, their professions, and work spaces. Mirza Sangin Beg addresses the issue of qaum most unselfconsciously and amorphously.

A real case study of an energy system based on a Solar Assisted Heat Pump (SAHP) fed by hybrid photovoltaic-thermal solar panels (PVT) and seasonal storage (SS) is presented in this paper. Exergy and exergy cost analyses are proposed as complementary methods for the assessment and better understanding of the efficiency of this cogeneration solar configuration. The system performance takes advantage of storage heat in summer, when the solar resource is high in Spain, and is then later consumed during the cold winter (heating season). The building is devoted to social housing, and it is currently under construction. The assessment is based on simulations developed using TRNSYS, a dynamic simulation software for energy systems. Results show that the unit exergy cost of the solar field is around 6. The cost of the seasonal storage is higher, about 13, and its formation is affected both by its own irreversibility and by the irreversibility of the PVT solar field. The cost of the heat delivered by the heat pump is around 15, being affected by all the upstream units and even by the grid. Besides, the analysis points out strategies for improving the system efficiency, such as increasing the size of the storage tank or improving the control strategy of the boiler.

With the widespread application of asphalt mixture, current demand from transportation managers for construction and maintenance of their pavement network consumes large numbers of aggregates. If agencies excessively favor to some certain kinds of excellent aggregates, the cost of construction could be considerably expensive. The major objective of this study is to determine the feasibility of utilizing dacite in asphalt mixtures. By means of Marshall, freeze-thaw, rutting and three-point bending tests, the performances of dacite and basalt asphalt mixture are compared. The results of the testing illustrate that dacite asphalt mixture is more susceptible to gradation and asphalt content than basalt asphalt mixture. Meanwhile it is showed that the performances of dacite asphalt mixture can be improved greatly with the involvement of additives including active mineral powder and cement. Furthermore, it is validated that dacite can be used as alternative aggregate in asphalt mixture.
