О преимуществах BIM-технологий вряд ли надо говорить подробно. Если коротко, то использование информационных 3D-моделей упрощает взаимодействие между участниками проекта: архитекторами, проектировщиками, поставщиками, строителями и заказчиком. Позволяет быстрее, а главное, на ранних этапах выявлять коллизии и избегать ошибок на стройплощадке. Да и просто сам факт использования BIM – это входной билет компании в отраслевую элиту.

Arrangement of Balconies with the Help of Hollow Core Floor Slabs The arrangement of balconies makes it possible to diversify facades of buildings and include them in the living environment of the apartment. During the construction of panel and frame buildings, the transition to the use of hollow-core slabs revealed the technical complexity of the organization of balconies in apartment buildings. The complexity is connected with the need for «suspension» of each plate to the upper structures in the scenarios of collapse of the underlying bearing structure. The article gives examples of solutions regarding the arrangement of balconies, loggias, facade cornices when using floor slabs with inter-hollow strengtheners. Possible scenarios of the behavior of the frame prefabricated structure after the sudden loss of the column as a result of emergency exposure are presented; the design of the node supporting floor slabs on the inner bearing plate in the scenario of elimination of the lower support of the external panel is also presented. Recommendations on the choice of binding reinforcement and the location of connections relative to the ends of the overlap are given.

Keywords: hollow core floor slabs, balconies, loggias, fasade cornices, progressive collapse, connecting rods.

Industrial Housing Construction: Yesterday, Today, Tomorrow The main performance targets for the construction industry are modernization, improving the quality of industrial construction, increasing the volume of commissioning up to 120 million m2 of housing per year. Profile departments are working out a scheme of transition from shared-equity funding to other forms of financing, in connection with the existing problem of defrauded investors, the solution of which ultimately rests on the shoulders of the state. The state, as the only player in the construction market with «long money», should offer citizens a new type of acquisition of housing, similar to the acquisition in leasing – an initial payment followed by a monthly rent, for a specified period of the contract. At the end of the contract, the citizen becomes the owner of the property.

Keywords: performance targets of construction industry, defrauded investors, project financing, mortgage, nationalization of construction industry, rent, modernization, industrial housing construction.

The Use of Domestic Pneumatic Equipment at Enterprises of Building Industry One of the time-consuming technological conversion of production of precast reinforced concrete structures at enterprises of the construction industry is the unloading of cement from railway cars (hoppers) at cement warehouses and transporting it to concrete mixing units. The use of outdated pneumatic screw pumps for cement pneumatic transport at most cement warehouses often disrupts the rhythmic work of warehouses, mainly due to the rapid wear of the pump screw. This leads to a decrease in productivity and high energy consumption of pneumatic screw pumps. The elimination of this disadvantage is most advisable by replacing the pneumatic screw pumps with the chamber pumps consuming only compressed air. The proposed chamber pump is characterized by simplicity of design, so that its production is accessible for repair-mechanical shops of construction enterprises, as well as high performance and reliability, which makes it possible to fit into the standards of wagons unloading. Molding processing in the production of precast concrete products and structures is fundamental, as it lays the consuming qualities and physical and technical characteristics of products. When forming internal wall panels, solid floor slabs in a vertical position, the main drawback is the heterogeneity of the concrete strength along the height of the product, as well as numerous pores and voids on the front surface of the products that require additional operations at the enterprises for their filling. It is proposed to use an internal pneumatic vibrator, which has a simple design, has the possibility to manufacture and repair on its own at the enterprise. Working drawings for a line of site and internal pneumatic vibrators of various nominal sizes, as well as a chamber pump for cement transportation have been developed. The accumulated practical experience in the technology of production of reinforced concrete products and structures shows the possibilities for improving the technological processes of production. Chamber pneumatic pumps passed the practical test, and also pneumatic vibrators (mounted, internal) of various design solutions significantly expand the capabilities of the factory technology.

Keywords: reinforced concrete products, chamber pump, construction industry, pneumatic screw pump, site pneumatic vibrator, internal pneumatic vibrator.

Composite Diagonal Flexible Connections for Three-Layer Concrete Panels – Panel Housing Construction of a New Level Currently, panel housing construction is undergoing significant improvements. If the modern «panel» already makes it possible to create beautiful, bright and diverse residential complexes with different types of facades and cladding, that over the issues of heat insulation and energy efficiency of such houses is actively working at the level of the government of the Russian Federation – legal requirements for energy efficiency of residential facilities are increased, and at the level of house – building plants new materials and construction technologies are introduced. So, at present, the technology of construction of panel houses from concrete three-layer sandwich-panels with insulation is widely used. For reliable connection of all sandwich-panel layers, diagonal flexible connections are used. At the market of large panel housing construction diagonal stainless steel ties are the most common. But at the same time they are a «cold bridge» – a place through which there are increased heat losses due to which the energy efficiency of the panel and the house itself respectively, is reduced, heating costs increase. Now, for reliable connection of all layers of the sandwich-panel, improving its reliability and energy efficiency, a modern solution is proposed – composite diagonal flexible connections. High corrosion and chemical resistance of the product, zero thermal conductivity and alignment of the temperature heterogeneity of the panel, the absence of «cold bridges», condensate and mold while reducing costs and increasing productivity – all this make it possible to create a house of improved quality, and panel construction of a new level. The article presents the results of tests of diagonal flexible connections for three-layer wall panels, widely used in housing construction. The advantage of composite diagonal flexible ties over metal ties is shown, the economic and practical feasibility of using such connections for houses of improved quality and the creation of a new level of panel housing construction is shown.

Keywords: diagonal flexible ties, concrete three-layer panels, energy efficiency, corrosion resistance, composite materials.

Evaluation of Effectiveness of Investment Project of Reconstruction of Large-Panel Housing Construction Enterprises Improving the efficiency of enterprises of large-panel housing construction is possible due to the use of flexible technologies. An example of this type of technology is the production of products on stationary rotary molding tables using removable magnetic side tooling. It makes it possible to organize the production of a wide range of products without creating a large park of metal molds. The estimation of efficiency of investments necessary for the organization of production of plate products on rotary molding tables is executed. The placement of the technological line in the existing production building is considered. The investment includes the cost of construction works on the reconstruction of the plant and the purchase of technological equipment. Calculations of commercial effectiveness indicators are made according to the rules of the existing methodological recommendations on assessing the efficiency of investment projects. The investment efficiency assessment was performed under the conditions of uncertainty of the investment project, incompleteness and inaccuracy of information about the conditions of its implementation. Part of the original data is adopted with due regard for the constraints established by official documents. Additionally, the method of parameter variation is involved. The production capacity of the processing line, the volume of capital investments and the amount of profit included in the cost of 1 m3 of products are selected by various factors. The duration of the calculation period is 10 years. The values of the profit rate and the volume of investments that determine the boundaries of economic efficiency of reconstruction depending on the productivity of the processing line are established.

Keywords: reconstruction, rotary forming tables, investment project, investment attractiveness, indicators of commercial efficiency of investments.

Organizational and Technological Solutions for Operational and Calendar Planning of Construction of a Monolithic Building The article is devoted to the problem of discrepancy between the design and actual schedules of construction of a monolithic building. As a result of the analysis of the existing problems of calendar planning, the need to improve the methodology of calendar planning of construction of residential monolithic houses in the interests of timely commissioning and achievement of high technical and economic indicators is revealed. In the methods of formation and calculation of flows, determination of the risk of untimely execution of works, as well as forecasting the increase in the cost of the project due to its long duration, is not taken into account enough. The method of variant modeling of the plan of construction and installation works with due regard for rational distribution of available resources on the basis of the Microsoft Project software complex (the project management program developed and sold by Microsoft Corporation) is offered. The method is developed on the basis of known planning algorithms, and includes new elements.

Keywords: monolithic construction, organizational-technological solutions, operative-calendar planning, simulation of calendar plans, stochastic models, PERT method, Microsoft Project, network graphics.

Analysis of Practical Experience: Advantages and Disadvantages The article describes the legislative changes that regulate the relationship between the state and citizens in the issues of the operation and overhaul of the housing stock. It is shown that the Moscow program of capital repairs of common property in apartment buildings took into account the experience of the regions that were the first to adopt such documents. On the example of the experience of capital repairs of eight apartment buildings (AB), located in different parts of Moscow, shortcomings in the development of project documentation for the overhaul of AB are classified, the most and least profitable, as well as unprofitable types of works are identified. It is noted that one of the main reasons for the poor quality of design is the lack of factual information that should be obtained during field surveys of buildings. The result of low quality design and the impossibility of changing the cost of work enshrined in the contract becomes considerable decrease in profitability of the contracting organization, as well as failure of the timing of overhaul. In the given examples of non-compliance of design solutions to the actually required amount of work, the differences in the estimates and the real costs of the contractor ranged from 12 to 70%. It is concluded that the complex execution of design and repair works by one company will make it possible to increase the responsibility of the contractor, optimize the estimated cost of major repairs, use the resources more efficiently.

Keywords: major repairs, regional program of major repairs, apartment buildings, engineering systems, control over repair quality, assessment of technical state, major repair fund, design of overhaul, major repair problems.
