Subject: the deterioration and technical condition of water supply and drainage pipelines in most of Russia’s settlements, the limitation of material resources for their restoration and renovation in conditions of housing and communal services reform, require a scientifically grounded approach to the reconstruction and modernization of these systems [1-4]. To solve these problems, the Government of the Russian Federation approved and introduced normative documents1, 2. According to them, the development of centralized water supply and water disposal systems is carried out only in accordance with the general schemes of these systems3. As part of these schemes, it is necessary to develop an electronic model of a centralized water supply and disposal system for an objective assessment of the impact of activities aimed at optimizing their work [5]. The algorithm for constructing and calibrating the electronic model of the city’s water supply system is the subject of this study. Research objectives: development of a methodology for constructing electronic models and algorithms of calibrations which are applicable to the Russian Zulu software. Materials and methods: for an objective assessment of the impact of long-term measures aimed at improving the operation of the water supply network, as well as the development of the city’s water supply system, we use modeling along with the implementation of an adequate electronic model. The adequacy of the electronic model is achieved via its calibration [6]. The object of the research is the water supply system of Minsk and Salavat in the development of electronic models for realization of their development and reconstruction directions. Results: based on the experience of implementation of a number of water supply systems (Ufa, Irkutsk, Penza, Orenburg, Tyumen, Salavat, Minsk), a methodology for constructing and calibrating electronic models was developed; the algorithms applicable to the Russian Zulu software and necessary for construction of models were also developed. Conclusions: the results of the work are implemented on a number of water supply systems in the cities of Russia and can be recommended for application of information technologies in electronic model realization, the assessment and analysis of the functioning of water supply systems and the optimization of their operation.

The article is an overview of various designs developed for joints of rod elements of space structures. Designs under consideration include those developed by domestic and foreign researchers and structural engineers. Space joints are clustered on the basis of their characteristic features, and their principal strengths and weaknesses are specified by the authors.The authors’ overview serves as the basis for an advanced structural solution developed for modular joints of space elements. A space joint consists of four space details having holes that are fastened to the central element by two bolts (screws). A flat plate with holes is attached to the edge of the central element. Space details and the core element are to have a gap between them. Rod ends are inserted into gaps and fastened to joints with bolts. The proposed solution may be used to reduce the material consumption rate (steel and plastic) and to simplify the assembly of structures. The solution proposed by the authors also improves the reliability of joints due to the integrity of elements, their rigid fastening to the central element, and the use of two cross-section bolts.

The article covers the formation of the pore structure of cement systems that harden at low and negative temperatures. Temperature fluctuations that accompany the hydration of cement systems can produce a substantial impact onto the chemical activity of the water in the course of hydration. These factors can produce an adverse impact on the formation of the structure of the cement stone and impair its performance characteristics. The formation of the structure of cement systems is dependent on the impact of specialized additives, including antifreeze agents that facilitate hydration at low and negative temperatures. The research of their action and the nature of their influence on the formation of the microstructure of the cement stone facilitate the purposeful adjustment of their properties. Therefore, modification of cement systems by specialized antifreeze components is a relevant objective of scientific and practical research.
Research of a classical cement system (a benchmark composition) and a cement system modified by a specialized antifreeze polymer-based additive (a modified composition) was performed to identify the impact of antifreeze additives onto the process of formation of its pore space.
Upon completion of the research project described in the article, the authors have concluded that antifreeze additives facilitate hydration of cement at low and negative temperatures and cause regular formation of the pore structure of the cement stone.

The author of the article argues that the Russian construction industry is in need of an effective management system. The essence of the potential management system is that the management impact, irrespective of its origin, must be recognized by individuals as a deliberate need that will bring them particular economic benefits.
Management of the construction industry as one of the most important constituents of the real economy may turn efficient in the event that it is in control of its production, real property and investment constituents in both, so to say, "horizontal" and "vertical" directions. Investment relations run through principal construction operations and any related activities; therefore, they must be represented in the functional responsibilities of the Ministry of Regional Development that is in control of the construction industry.
The construction market accommodates various legal entities. Most of them are controlled by co-owners whose work is under the control of management partners. It is essential that any economic levers that they possess are not predominant. It is vital for any decisions that they propose to be supported by other co-owners (or their majority). And this is feasible in the event of good business relations between the parties.

This article covers data transfer processes in the automated system of parallel design and construction. The authors consider the structure of reports used by contractors and clients when large-scale projects are implemented. All necessary items of information are grouped into three levels, and each level is described by certain attributes. The authors drive a lot of attention to the integrated operational schedule as it is the main tool of project management. Some recommendations concerning the forms and the content of reports are presented.
Integrated automation of all operations is a necessary condition for the successful implementation of the new concept. The technical aspect of the notion of parallel design and construction also includes the client-to-server infrastructure that brings together all process implemented by the parties involved into projects. This approach should be taken into consideration in the course of review of existing codes and standards to eliminate any inconsistency between the construction legislation and the practical experience of engineers involved into the process.

Logistics is an effective tool in business management. Metal trading business is a part of metal promotion chain from producer to consumer. It's designed to serve as a link connecting the interests of steel producers and end users. We should account for the specifics warehousing trading. The specificity of warehouse metal trading consists primarily in the fact that the purchase is made in large lots, and the sale - in medium and small parties. Loading and unloading of cars and trucks is produced by overhead cranes. Some part of the purchased goods are shipped in relatively large lots without presales preparation. Another part of the goods undergoes presale preparation. Indoor and outdoor warehouses are used with the address storage system. In the process of prolonged storage the metal rusts. Some part of the goods is subjected to final completion (cutting, welding, coloration) in service centers and small factories, usually located at the warehouse. The quantity of simultaneously shipped cars, and the quantity of the loader workers brigade can reach few dozens. So it is necessary to control the loading workers, to coordinate and monitor the performance of loading and unloading operations, to make the daily analysis of their work, to evaluate the warehouse operations as a whole. There is a need to manage and control movement of cars and trucks on the warehouse territory to reduce storage and transport costs and improve customer service. ERP-systems and WMS-systems, which are widely used, do not cover fully the functions and processes of the warehouse trading, and do not effectively manage all logistics processes. In this paper the specialized software is proposed. The software is intended for operational logistics management in warehouse metal products trading. The basic functions and processes of metal warehouse trading are described. The effectiveness indices for logistics processes and key effective indicators of warehouse trading are proposed. The developed software permit taking into account the described above specifics of metal products warehouse trading. The software can be easily integrated with ERP-systems and WMS-systems. The software contains the module of consolidation, which allows evaluating and comparing the quality of the logistics operations in a group of companies. The software was implemented and effectively used in a large metal trading company, which has few dozens of warehouses. Some results of mathematical simulation are presented.
