Ways to Improve Construction Efficiency

The quantum model of the development of intelligence as a theoretical basis of the theory of technological development. Construction technology life cycles

A. Osipov — 2024-07-06

The article outlines the main provisions and analyses the main models of intelligence development using a historical approach. A quantum model of intelligence development is proposed, which reveals the logical essence of intellectual processes occurring at the levels of individual and integral intelligence. Individual and integral intelligences can remain in stationary states for a long time, in which the intelligence and the system of intelligences have "volumes". Any change in the "volume" of intelligence occurs only with a complete transition from one state to another, the mechanism of intellectual transitions is a discrete process. It is shown that the pattern of growth of the "volume" of integral intelligence obeys the exponential law. The volume of integral intelligence increases like an intellectual flash; the process of development of integral intelligence is discrete, cyclical and has a constant parameter – the lag of integral intelligence, which belongs to the interval of 6–8 years. The relationship between the development cycles of integral intelligence (its outbursts) and "Kondratiev's big cycles" is established. For each lag of integral intelligence, its "volume" increases, relative to the initial level, by the value of the exponent, and each "great Kondratiev cycle" has from 6 to 8 lags of integral intelligence, which precede waves of technical inventions and their practical application in the form of innovations, that is, innovative products and technologies. The development of construction technologies is a continuous and irreversible process of increasing their effectiveness over time, and is generally described by s-shaped curves that are tangent to the contour curve characterizing the integral effectiveness of public labor in the construction industry. Technologies have their own life cycles, consisting of stages that differ in the level of relative effectiveness, namely: the stage of introduction and initial diffusion, the stage of maximum diffusion, the stage of rationalization, the stage of obsolescence. The existence of technologies at the stage of aging is impractical.

Technological factors of the process of soil compaction in complex construction conditions

I. Umanets — 2024-07-06

The article is devoted to the technology of mechanical soil compaction in difficult construction site conditions. The compaction of the soil occurs due to certain force loads on the soil. The actuality of the soil compaction process, which ultimately determines the quality of construction product, was emphasized. The basic physical and mechanical properties of soil and technological parameters of the compaction process were given. Attention is focused on the fact that the choice of soil compaction technology in difficult conditions is based on the understanding of the fact that it is necessary to consider the compaction process as a complex model of the interaction of the compaction machine with the base soil. It is noted that the choice of the mode of static or dynamic action on the base soil depends on the correct choice of the mathematical model of the machine-soil interaction system. An overview of the existing methods of soil compaction was conducted and the feasibility of researching methods of soil compaction in difficult construction conditions was substantiated in order to select the optimal set of compaction equipment. An analysis of existing soil compaction technologies was carried out with the aim of determining the optimal technological parameters of the soil compaction process in difficult construction conditions. The technological scheme of the soil compaction process in difficult conditions was given. The technology of the works is described, taking into account the properties of the soil, the method of compaction, the parameters of the compaction equipment, as well as the conditions of the works. The main technological parameters of the soil compaction process are proposed - the thickness of the compacted soil layer, the number of passes of the compaction machine, as well as the speed of its movement. A theoretical-experimental method of finding the optimal parameters of the interaction of the compaction machine with the base soil is proposed in order to establish the optimal limits of the varied parameters of the technological process of soil compaction in complex construction conditions. An analysis of structural and technological parameters of compacting machines was carried out with the aim of effective use in the conditions of construction production. Basic recommendations for choosing a compaction method and a set of compacting equipment were given, depending on the type of soil and conditions of work.

Elimination of the consequences of armed aggression in Ukraine: application of modern technologies in the inspection of damaged buildings and structures

I. Shatrova — 2024-07-06

This study aims to consider the improvement of technical inspection methods in the context of military conflict. Taking into account the factor of human safety in the survey process, the search for optimal methods and technologies for data collection and analysis is carried out, in particular, the use of modern technologies such as unmanned aerial vehicles (UAVs) and geographic information systems (GIS) is considered. The use of drones allows for quick and efficient surveys of hard-to-reach areas and the collection of high-quality damage data. The integration of UAVs with GIS provides a systematic view of large-scale destruction problems and helps to make informed decisions on how to address the consequences of armed aggression. Despite the advantages of using these technologies, their limitations should be taken into account. The combination of different survey methods allows to obtain the most complete and accurate information about the condition of buildings and structures, which is key in making decisions on the restoration and reconstruction of the affected areas. The study examined the practical use of these technologies within the framework of the Rebuild ua project, which digitized the main destructions in Chernihiv, Sumy, and Kyiv regions. The use of unmanned aerial vehicles in combination with geographic information technologies allows to systematize, analyze, obtain visual information and images with geometric data, which simplifies the process of damage assessment and decision-making during the survey procedure. GIS technologies are also capable of analyzing geographic data, visualizing damage on a map, locating damaged objects and assessing their damage. The integration of GIS technologies and unmanned aerial vehicles with other systems makes it possible to simplify decision-making on the priorities of liquidation and recovery.

Numerical study of the stability of a shell of minimal surface on a circular plan with regard to geometric nonlinearity under thermal and power loading

H. Ivanchenko — 2024-07-06

Great progress has been made in the field of thin elastic shells calculation, both in the field of mathematical theory, which, based on the Kirchoff-Love hypothesis in surface theory, is engaged in the construction of various forms of important design equations and the development of accurate methods for their solution, and in the field of structural and applied mechanics, which is based on the specified initial parameters and accepted additional working hypotheses, which are determined by experimental data, and which deals with simplification of calculation schemes and methods of their solution, which will be convenient for engineering calculations.

The geometric nonlinearity of the equations is achieved by taking into account the quadratic term in the expressions of the component of the membrane deformation tensor and changes in the deformed shape of the middle surface of the shell. The solution of the system of nonlinear equations is constructed by the iterative method of continuation of the solution in the parameter, taking into account the Newton-Kantorovich method.

When operating thin shells, they can be subjected to harsh conditions - under the influence of various temperature and force loads. Large, inhomogeneous temperature fields affect the mechanical properties of the material and can cause large deformations, and can be the most determining factor affecting the strength and load-bearing capacity of the shell as a whole.

Geometrically nonlinear problems are mainly used to formulate structural stability problems. In most cases, the stability problem can be solved by reducing it to a linear formulation under natural oscillations.

Geometrically nonlinear problems are problems of elasticity theory in which nonlinearity in the dependence of strains and displacements is taken into account, while stresses and strains are related linearly. Taking into account nonlinear components of deformations is necessary for the calculation of flexible thin-walled structures.

In the numerical experiment, the eigenvalues of the stability factor are equal to 1.013, which means that there is no margin of safety and stability in the shell, and we can further use these results for multicriteria parametric optimization, and the results of the study are confirmed by the authors' methodology for objects where optimization of the shell geometry is taken into account.

Justification of the feasibility of using arrival reinforced concrete vaults

H. Tonkacheiev — 2024-07-06

The article discusses constructive and technological solutions for the use of reinforced concrete vaults. At this stage of society's development, in the difficult conditions of survival during hostilities, the issue of the safety of people's lives becomes urgent. The structural solution of buildings in the form of vaults is suitable for solving similar problems. The criterion for choosing a constructive solution is the reliability and functional volume of the building. The most reliable are reinforced concrete monolithic vaults made of modern materials. The most reliable is the arrow-shaped vault. The analysis of different forms of vault arches showed that unlike flat and full cylindrical vaults, pointed vaults have a more useful use of wall space at a height of up to 6.0 m, which makes the premises more functional. The criterion for choosing a technology is the speed of building the vault. The problematic issue of erecting monolithic reinforced concrete vaults remains the imperfect technology of arranging formwork, reinforcement and concreting. When concreting the curvilinear convex surface of the structure, the concrete slips. This article is dedicated to solving this problem. When switching to pointed vaults, it is not known how much the technology of performing the processes of formwork installation, reinforcement and concreting changes. The analysis of the existing technologies for the construction of monolithic vaults showed that the existing structural and technological solutions do not solve the problem of accelerating the construction speed. In order to prevent the process of slipping of concrete, the use of fiber is proposed. Additional studies are planned to study the effect of fiber concrete on sliding. The need for conducting research in the direction of improving constructive and technological solutions, improving the means of mechanization of the process, and in the direction of creating a system of normalization of labor costs for the processes of erecting pointed vaults has been identified.

Еfficiency of floating coating for fire protection of wooden buildings

O. Bondarenko — 2024-07-06

Studies of the effect of wood flame retardant on ignition have established the parameters of flame propagation and combustion suppression, which makes it possible to influence this process. It is proved that they consist in creating a layer on the surface of the material, which prevents heating to a critical temperature, when intensive decomposition begins with the release of the required amount of flammable gases and their ignition. This makes it possible to determine the effect of fire protection and the properties of protective compositions on the process of inhibiting the rate of wood burning. During the tests of wood samples it was found that the untreated sample took 52 s, the flame spread throughout the sample for 100 s instead, the sample fire-retardant "FIREWALL-ATTIK" did not catch fire, impregnating solution ВС-13 and "FIREWALL-SV-1", Namely a mixture of 271.1 g/m², took 570 and 560 s, the spread of flame on the surface occurred only in the first areas, the maximum flue gas temperature was 86 and 89 °C for more than 5 times, and the flammability index decreased to 4. For the sample protected by "FIREWALL-LAC" ignition occurred at the last second, the flame was recorded at level 0. For the sample fire-protected by "FIREWALL-WOOD" coating no ignition occurred, combustibility index 0. Due to this, it became possible to determine the conditions for changing the parameters of combustion and braking in fire protection of wood by forming a barrier to thermal conductivity. The results of comparing the experimental data of wood burning rate with the obtained analytical equations showed the correspondence between them. Thus, there is reason to argue about the possibility of targeted regulation of fire protection processes of wood by using fire-retardant coatings capable of forming a protective layer on the surface of the material, which inhibits the rate of wood burning.

Comparison of structure variants covering of storage building

Ye. Misiura — 2024-07-06

In connection with the constant increase in the volume and pace of freight transportation throughout the world, the creation of high-quality storage buildings is of particular importance. Unfortunately, in domestic practice, this aspect is given relatively little attention, and even specialized standards for the classification of building structures practically bypass this issue. However, in international practice, storage buildings are a more important construction object, which has a specialized classification based on a set of basic indicators. Moreover, the higher the class of the building, the higher its status and importance and, accordingly, the higher income it can bring to its owner. Therefore, the issue of upgrading the class of a storage building is quite relevant and significant.

One of the parameters that directly affects the classiness of the storage building is the distance between the columns. In the course of the research, three structural variants of the roof of a storage building with a steel frame, located in the city of Dnipro, were considered. The variants differed in the construction of the supporting beam and provided the possibility of overlapping spans of 36 m, 24 m and 12 m with a total span of the storage area of 72 m. During the numerical analysis, the finite element method was used using the domestic design and calculation complex SCAD.

As a result, it was established that the design variant using rafter trusses with a span of 24 m is more effective in terms of mass indicators than the variants for using rafter trusses with a span of 36 m (by 60 %) or beams with a span of 12 m (by 130 %). This made it possible to raise the class of the storage building according to the international classification from class B+ to class A. Detailed drawings were developed for the selected design option, which are planned for implementation in project practice.

Test results of steel nails for wooden structures

L. Klochko — 2024-07-06

The new standard for the design of wooden structures, which was recently introduced into the practice of design in Ukraine, contains updated modern approaches to calculation and design, including nodal nail connections. Such approaches are associated with the use of more complex calculation expressions that take into account a larger number of influencing factors. The strength of steel nails for nailed joints is among such factors. However, there are currently no available data on the strength and deformation characteristics of nails in the specialized or reference literature. In addition, these characteristics depend on the product supplier.

Experimental studies remain the only reliable way to determine the mechanical characteristics of steel nails. They were conducted for nails of two diameters - 4.2 mm and 5.5 mm. The tests were performed on the UG20/2 universal machine. In the course of research, a diagram of the operation of steel under load was automatically constructed, which turned out to be not entirely characteristic of the classical diagram of carbon steel. According to the author's assumption, the steel of the nails was previously subjected to mechanical processing in the form of slander.

Quantitative values of the obtained mechanical characteristics depend somewhat on the diameter of the nail, but are generally quite stable. The yield strength is in the range of 560-650 MPa, the strength limit is in the range of 620-690 MPa, and the relative longitudinal elongation is in the range of 35-50%. It is also worth noting that the obtained mechanical characteristics based on the test results of 5 samples have a rather small spread within 10 %. This testifies to the rather high quality of steel for the manufacture of nails on the one hand, as well as to the high quality of the nail manufacturing process itself.

As prospects for further research in this direction, it is recommended to expand the range of nails for testing both in terms of diameters and in terms of suppliers of these products in Ukraine.

Research of the deployment of the consulting engineer profession in Ukraine. Public requirements for the profession responsibilities. International practice of implementing standards

О. Tugay — 2024-07-06

The article is based on the analysis of legal requirements and regulations of Ukraine as for the approval of qualification features of the consulting engineer profession [1]. Given the expertise of international institutions acquired through international forms of sub-contract agreements, which greatly impacts all participants of the investment in construction, the article highlights the objectives of a rapid development in Ukraine of the engineering and consulting service market model integrated in the generally recognized international industrial standards.

The international practice and deployment of the new consulting engineer profession is assessed in compliance with the decision made under the Decree of the President of Ukraine “On Certain Measures to Create Condition for the Development and Improvement of Motorway Quality” [2]. The data brought to the article and the analysis of the research suggest using the international practice in construction of both regular structures and engineering works. The target indicator implies an opportunity to apply international standards that, in their turn, will contribute to a better adaptation of the best global practices in Ukraine, provided that there are coordination and cooperation established with international communities. The necessity to adjust the established standard form of agreement approved by the central executive authorities to the relevant international standards in effect as for unified interpretation and understanding of distinguishing features.

The research unfolds a complete set of responsibilities required for the consulting engineer profession and streamlining of the profession structure in pursuance of categories in terms of their simplification, leading to a more comprehensive monitoring, high quality project management, and construction quality assurance. Decisions made on the basis of international forms of agreements accepted worldwide will promote a quick transfer to the unified system involving communication with international financial aid providers and organizations that, amidst the wartime and complicated economic position in Ukraine, have accumulated sufficient resource along with Ukraine’s government to ensure that immediate expenditures for national security and defence, critical infrastructure maintenance are made. This issue becomes increasingly focal within the meaning of the greater task through the development and recovery of the country after the aggression waged by the Russian Federation. Therefore, the essential interaction project provides for cooperation with international organizations, financial institutions and foundations as for sharing expertise and developments in attracting global knowledge and forms of investment and construction.

Shallow tunnel construction technology using pneumatic formwork

H. Shpakova — 2024-07-06

This article considers the technology of underground tunnel construction using pneumatic formwork, which aims to improve and make easier construction of tunnel facilities. Having familiarized with problems of the construction, in particular subway facilities, and analyzed its basic aspects of this construction, I would like to propose using this technology for construction of shallow subway tunnels. The peculiarity of this technology is to optimize a building process and improve quality characteristics of constructed tunnels by replacing prefabricated elements with a solid monolithic tunnel which is built directly on the construction site. The fundamental technological difference is applying pneumatic formwork instead of standard formwork panels and systems of support posts and longitudinal beams. The main working element in pneumatic formwork system is a dome-shaped shell made of a durable membrane that serves as a formwork for concrete. This membrane is filled with air under high pressure using compressors and maintains its shape throughout the entire technological process until the concrete mixture sets. Such pneumatic formwork includes much fewer mounting elements, which improves technical and economic performance. Utilization of pneumatic formwork in modern construction can be a key point in improving technical and economic indices, as construction of such a formwork system takes much less time than for more common panel systems.

The development of pneumatic formwork technology has potential not only in the construction of subway but also in other construction areas. As an example, this method can be useful in solving an urgent issue of building bomb shelters for population, and even for enterprises because pneumatic formwork can be made in various shapes depending on the requirements for a particular facility

Improvement of technological solution of erection large-span coatings by lifting modules

O. Ignatenko — 2024-07-06

After studying the organization and technological aspects of existing solutions for lifting large-span coatings through pulling and pushing, a new technological approach for erecting coatings using lifting modules was developed. According to the developed solution, first, by methods of free lifting using self-propelled boom cranes, twin columns of the frame, inter-column beams and bundles are mounted. On the foundations between the paired columns are placed lifting modules, which consist of hydraulic jacks and lifting platforms. Installation column heads are installed on lifting platforms. The external surfaces of carcass columns are secured with lifting retainers that are made of cantilevered support platforms, hydraulic cylinders, and movable crossbars. On low scaffolding, structural and technological blocks of coatings are increased. At that bearing crossbars of coatings are introduced into space between paired columns of frame and lowered onto heads of mounting columns. At the second stage of installation works by method of pushing out the coating is moved to the design height provided that supporting crossbars of the coating are supported on the heads of growing installation columns. In the process of growing the sections of the installation columns, the load from the raised coating and sections of the installation columns is alternately transferred to the hydraulic jacks of the lifting modules and the girders of the lifting locks. According to the developed solution, all the processes of growing the sections of installation columns and moving the roof girders from the foundation level to the level of the heads of the frame columns are automated Work on the construction of coatings can be performed in conditions of dense buildings on the site, the size of which does not exceed the overall dimensions of the rising coating. The volumes of high-altitude works have been reduced to operations for fixing the bearing crossbars of the coatings between the heads of the paired columns of the frame, which allows to significantly reduce the total time of lifting works.

Optimization of organizational and technological parameters of the construction of civil buildings

K Mishuk — 2024-07-06

The article provides solutions for optimizing organizational and technological solutions for the construction of civil buildings. The article formulates the goal and describes the research methodology. Optimizing the organizational parameters of construction requires a comprehensive approach, which will include the implementation of modern technologies, effective management of resources and constant improvement of technological processes. The use of such methods allows not only to increase the productivity and quality of work, but also to reduce costs and time spent, while ensuring the successful completion of construction objects. The search and identification of factors made it possible to systematize them: the influence of compactness of the construction site; factors complicating the transport of structures; factors complicating the consolidation of constructions; factors complicating the installation of structures; factors of work performance technology; factors describing the constructive and planning solution of buildings. Another network model may include options for completing the construction of the facility. The use of various models ensures high efficiency of the management system based on organizational and technological factors. However, a large volume of initial and current information requires careful organization of the database structure and intensive use of computer technologies. Computerization of the management process based on organizational and technological factors, as well as design, supply, financing and other processes requires clear formalization and creation of information technology. One of the possible directions of formalization of management technologies is the construction of economic-mathematical models, on the basis of which the management system is formed.

The role of the mathematical model of the complex assessment of the compatibility of combination of construction processes

I. Arutiunian — 2024-07-06

The scientific article defines the role of mathematical modeling in the assessment of construction production regarding the admissibility of a combination of processes. Special attention is paid to the comprehensive study of the stages of construction in order to identify the main types of work and identify possible ways of combining them. In addition, the existing methods of construction organization were analyzed. Based on the conducted research, the course of model development was determined. The article examines and analyzes the complex influence of organizational and technological factors that affect construction, develops a mathematical model of the researched process in the form of systems of equations connecting the indicators of the researched process and its variable parameters, the variation of which studies the behavior of the process. The need for the use of information technologies in a construction company, the development of a mathematical model of the resource planning process and the selection of suppliers, and the requirements for the development of an information system. Based on the received relationships of qualitative and quantitative parameters, a model is developed and an algorithm for its calculation is built. In connection with the above, it is obvious that the development of such a model will allow a comprehensive assessment of the admissibility of combining construction processes. Construction of objects is a process in which implementing organizations, suppliers and consumers of material and technical resources, vehicles and other elements interact in a complex relationship. At the same time, the performance of work is affected by many different, in particular random, factors. A mathematical model is proposed for their influence, which will allow taking into account the joint influence of various factors, taking into account random factors of influence. Consider the value of mathematical modeling during the analysis of a potential combination of processes in construction. We focus on the study of construction processes, identify the main stages of work and identify methods of combination. We will analyze the construction methods used and determine their modeling methods.

Strategic reconfiguration as a component of the potential of participating enterprises in the implementation of public-private partnership projects

H. Kolisnyk — 2024-06-28

In the modern conditions of the economic development of the state and the private sector, there is a need for cooperation for the implementation of socially significant projects. One of the effective mechanisms of such cooperation is public-private partnership (PPP). The successful implementation of PPP projects largely depends on the ability of enterprises to make strategic adjustments, which involves flexibility, adaptability and the ability to innovate.

The results of the study can be useful for managers of enterprises participating in PPP projects, as well as for representatives of state bodies responsible for the development of public-private partnerships. They will help to understand the importance of strategic reconfiguration and its impact on increasing the competitiveness and sustainability of enterprises in a dynamic market environment.

Strategic reconfiguration of components of the potential of enterprises participating in the implementation of public-private partnership projects is a relevant topic in the modern economic environment. This research work is aimed at analyzing the strategies used by enterprises to adapt to the conditions of implementation of such projects, considering their internal potential and capacity for innovative and transformational changes. The abstract discusses key aspects of strategic management, including the impact of the regulatory environment, financial and organizational aspects of the preparation and implementation of PPP projects. The study also emphasizes the importance of strengthening partnerships between the public and private sectors, contributing to the creation of sustainable investment projects and increasing the competitiveness of economic participants.

Public-Private Partnership as a tool for crisis management in the construction industry

O. Kalinin — 2024-06-28

Public-private partnerships (PPPs) are becoming an increasingly important tool for infrastructure development, improving the quality of public services, and stimulating economic growth in Ukraine. The article analyzes the current state of PPP in Ukraine, identifies the main problems, proposes elements of crisis management, and outlines the prospects for the development of PPP in the future. The types and terminology of PPP contracts are studied. The main characteristics of PPPs in Ukraine are provided, including: duration of contracts: 20-30 years, which provides an incentive for the private party to take into account the costs of providing services at the stage of project development; types of projects, responsibilities of the private party; payment mechanism. A key feature of PPPs is that the assets or services provided are defined in terms of outcomes rather than inputs, i.e., they define what is needed rather than how to do it. The analysis of PPPs in Ukraine proved that there are a number of problems that complicate the implementation of PPP projects. The main ones are the imperfection of legislation, the lack of clear mechanisms for distributing risks, bureaucracy and corruption. During 2010-2023, Ukraine adopted a number of regulations governing public-private partnerships (PPPs) and concessions. The periods of active legislative regulation were 2010-2011 and 2019-2023. Regulations play an important role in minimizing risks and effective crisis management in this area. It is noted that there is a limited number of effective mechanisms for distributing risks between the State and private investors, which leads to the shift of the main burden to one of the parties, which reduces the attractiveness of PPPs for investors. Studies show that only 35% of PPP projects in the construction industry have adequate risk-sharing mechanisms. the structure and possible consequences of the main risks that public-private partnership (PPP) projects may face in different phases of their implementation are provided. It is recommended to take into account their importance when allocating risks. It is proved that in practice a qualitative approach to assessment is used more often. Public-private partnership is a powerful tool for infrastructure development and crisis management in the construction industry. However, for its successful implementation, it is necessary to improve the regulatory framework, increase institutional capacity and ensure transparency of processes.

Seistenism – a new look at the concept of sustainable building

V. Skakun — 2024-06-28

The article examines the current state of the implementation of sustainable development approaches in construction enterprises and construction projects, and also considers construction from the perspective of Seistenism.

Seistenism is a new concept in economic development and construction that focuses on sustainable, efficient and technologically integrated construction practices. This concept combines building principles and approaches from various disciplines, including architecture, construction and civil engineering, ecology, environmental economics and environmental science, to create a structure that is not only functionally and aesthetically appealing, but also environmentally responsible and sustainable. to changing climatic conditions, while ensuring economic efficiency and minimal impact on the environment. Key elements of Seistenism include the use of renewable materials, energy-efficient designs, and integrated smart technologies to optimize building performance. The concept advocates a holistic approach to construction, which takes into account the entire life cycle of a building, from design and construction to operation and final dismantling of building structures and liquidation of the facility. This approach aims to minimize the impact of buildings on the environment, reduce resource consumption and promote the health and well-being of residents. In addition, Seistenism emphasizes the importance of community involvement and the inclusion of local cultural and environmental contexts in the design process. By fostering collaboration between stakeholders, including architects, engineers, developers and the community, systemicism involves creating buildings that are not only sustainable, but also culturally relevant and economically viable. Applying systemic principles to construction can lead to significant progress in the industry, fostering innovation and encouraging the widespread adoption of sustainable practices. Ultimately, Seistenism represents an advanced approach to construction that aligns with global efforts to combat climate change and promote sustainable development.
