Ways to Improve Construction Efficiency

Principles and criteria of sustainable development as factors of transformation of management systems in construction

Taras KOZAK — 2026-02-26

The principles and criteria of sustainable development under contemporary conditions acquire the status of system-forming factors in the transformation of management within the construction industry. Construction, as one of the most resource-intensive sectors of the economy, directly affects environmental balance, social stability, and the economic dynamics of territories, which necessitates a reconsideration of traditional approaches to project and enterprise management. The formation of management systems based on sustainable development implies the integration of environmental, social, and economic criteria into strategic planning, budgeting, production organization, and performance control processes.

The study systematizes the fundamental principles of sustainable development – integrity, long-term orientation, resource efficiency, social responsibility, institutional transparency, and adaptability – as the foundation for transforming management mechanisms in construction. It is substantiated that sustainability criteria should be formalized through a system of measurable indicators, including energy efficiency metrics, carbon footprint levels, material circularity, social inclusiveness, occupational safety, and the economic return on investments.

The transformation of management occurs across three dimensions: strategic, operational, and digital. At the strategic level, ESG-oriented planning and the integration of circular economy principles are implemented. At the operational level, technological processes are optimized with consideration of the life cycle of facilities, waste minimization, and the adoption of green standards. At the digital level, a sustainability monitoring system is formed based on BIM technologies, data analytics, and automated performance control platforms.

Furthermore, the implementation of the sustainable development concept in construction requires a transition from fragmented initiatives to an integrated management model in which environmental, social, and economic parameters function as interrelated variables within a unified system. It is determined that the effectiveness of transformation depends on the institutional capacity of enterprises to implement ESG standards, conduct regular non-financial reporting, and ensure transparency in decision-making processes.

Approaches to the formation of strategic goals and criteria for their achievement in management systems

Yaroslav KUZMICH — 2026-02-26

The formation of strategic goals in modern management systems is viewed as a comprehensive process that integrates analytical, systemic, and behavioral components of management under conditions of dynamic environmental change. Strategic goals are considered an integrative element that ensures the translation of an organization’s mission and vision into measurable performance benchmarks, coordinates resource allocation, and determines the vector of long-term development. It is substantiated that the effectiveness of a management system directly depends on the logic of goal formation, their hierarchical structuring, and the presence of clearly defined achievement criteria.

The key approaches to the formation of strategic goals are systematized: goal-oriented, systemic, behavioral, and adaptive. It is demonstrated that the goal-oriented approach ensures hierarchical consistency of strategic, tactical, and operational objectives; the systemic approach makes it possible to consider environmental influences and cross-factor interdependencies; the behavioral approach integrates subjective decision-making factors; and the adaptive approach focuses the system on flexibility and scenario planning under uncertainty.

Particular attention is paid to aligning strategic goals with the organization’s mission and vision, which is considered the foundation of strategic coherence. The use of integral alignment indices and correlation models is proposed to quantitatively assess the level of strategic consistency. It is proven that formalizing this linkage minimizes the gap between declared strategic intentions and actual managerial actions. Approaches to defining criteria for achieving strategic goals are disclosed, including the application of the SMART principle, KPI systems, and multifactor regression models for performance evaluation. The feasibility of using algorithm-based structures for developing criteria is substantiated, ensuring monitoring transparency, adaptability, and the possibility of integrating digital analytical tools.

Additional emphasis is placed on the necessity of implementing digital platforms for strategic monitoring, which ensure synchronization of goals across different management levels and automated tracking of deviations from planned parameters. It is shown that the integration of business analytics systems, forecasting tools, and scenario modeling enhances the validity of strategic decisions and fosters a results-oriented management culture. Such an approach creates the preconditions for strengthening organizational strategic resilience, competitiveness, and long-term adaptability in the context of structural economic transformations.

Study of correlations between production and operational characteristics and indicators of ecosystem balance

Dmytro NIKOLAYKO — 2026-02-26

The study of correlations between production and operational characteristics and indicators of ecosystem balance is aimed at forming an integrated analytical approach to assessing the environmental impact of construction activities. The paper substantiates the need for an interdisciplinary integration of ecological, economic, and technological tools to quantitatively determine the relationships between parameters of energy consumption, resource use, CO₂ emissions, waste management, and changes in biodiversity status. It is demonstrated that traditional approaches to environmental impact assessment do not provide sufficient analytical depth without the application of correlation and regression models, system modeling techniques, and Life Cycle Assessment (LCA).

Conceptual models of interaction between production processes and ecosystem indicators have been developed, enabling the formalization of cause-and-effect relationships between technical and technological parameters and changes in environmental stability. Mathematical relationships are proposed to assess the impact of energy consumption on CO₂ emissions and to model biodiversity changes under the influence of production factors. It has been established that the integration of LCA models, environmental monitoring systems, and risk assessment methods (FMEA, HAZOP) enhances the accuracy of forecasting environmental consequences of construction activities.

It is proven that optimization of structural parameters of the process-technological environment in construction – particularly the selection of materials, energy consumption patterns, technological solutions, and waste management systems – significantly reduces environmental risks and contributes to achieving ecosystem balance. The expediency of applying comprehensive multifactor models is substantiated, as they allow identification of the most sensitive production parameters and the development of optimization strategies in accordance with the principles of sustainable development.

The practical significance of the results lies in the possibility of applying the proposed models for strategic planning of environmentally oriented construction production, minimizing the ecological footprint, and increasing resource efficiency within the industry.

Identification of structural and functional deficits in management systems of construction enterprises

Oleksandr SHLAPAK — 2026-02-26

The identification of structural and functional deficits in the management systems of construction enterprises is considered a key direction for enhancing their organizational resilience and adaptability under conditions of increasing complexity of development processes. In the contemporary construction sector, characterized by multi-project environments, a high level of cross-functional integration, and significant informational intensity, managerial dysfunctions increasingly acquire a latent character and accumulate in the form of structural and procedural gaps.

The study systematizes the concept of structural and functional deficit as an integral set of strategic, operational, informational, communication, and institutional imbalances that reduce the coherence of an enterprise’s managerial contours. A multi-level model for their identification is substantiated, combining organizational diagnostics, analysis of information asymmetry, investigation of latent deviations in business processes, and assessment of the system’s integral deficit load.

Special attention is given to the phenomenon of latent deficit accumulation arising within cross-functional interactions and remaining unnoticed for extended periods due to the inertia of control procedures. It is demonstrated that information asymmetry between functional blocks (financial, scheduling, logistics, legal, analytical) creates preconditions for cascading disruptions in managerial decision-making. The formalization of information asymmetry levels and cumulative deficits through integral functions of time lags and local deviations is proposed.

It is proven that timely diagnostics of structural and functional deficits enables the development of analytical maps of managerial instability, identification of critical overload zones, and design of business process restructuring scenarios. The practical significance of the research lies in the applicability of the proposed models to enhance synchronization of information flows, reduce systemic risks, and ensure the strategic coherence of management within construction enterprises.

Functional and structural analysis of the components of the mechanism of intra-firm technology transfer in the construction industry

Oleksandr DUBENSKYI — 2026-02-26

The functional and structural analysis of the components of the mechanism of intra-firm technology transfer in the construction industry is aimed at a systemic understanding of the processes of generation, adaptation, transfer, and scaling of innovations within the organizational structure of an enterprise. In the context of digitalization, increasing complexity of development projects, and high market competition, effective internal technology transfer becomes a key factor in sustaining innovation dynamics and ensuring the long-term competitiveness of construction companies.

The study substantiates that the mechanism of intra-firm technology transfer has a multi-component nature and includes organizational and coordination, information and communication, technological and logistical, analytical and metric, and human resource blocks. Their integration forms a comprehensive knowledge management infrastructure that ensures the replicability of innovative solutions across different divisions of the enterprise. It is established that the fragmentation of technological innovations, the localized nature of their implementation, and dependence on the human factor necessitate a structural decomposition of the transfer mechanism in order to identify gaps, duplications, and functional imbalances.

A staged transfer analysis model is proposed, encompassing technology generation, its adaptation to specific project requirements, transfer between structural units, and performance monitoring. It is proven that a key element of efficiency lies in the formalization of transfer indicators through a KPI system, BI analytics tools, and digital dashboards that provide feedback and support managerial decision-making.

Special attention is given to the role of digital platforms (BIM, ERP, CDE, cloud services, and project management systems), which create a unified information environment for the storage, standardization, and scaling of technological solutions. It is substantiated that the integration of digital tools with organizational transfer procedures creates the conditions for forming an internal technological ecosystem of the enterprise.

The practical significance of the results lies in the possibility of applying the proposed functional and structural approach to designing effective management models for intra-firm technology transfer, enhancing synchronization among departments, reducing costs associated with repeated solution development, and ensuring technological continuity within construction companies.

Key factors determining the effectiveness of material and technical support organization

Oleksandr IVANYNA — 2026-02-26

The effectiveness of material and technical support (MTS) organization in the construction industry is determined by a complex of interrelated production-technological, organizational-managerial, financial-economic, information-digital, and external economic factors that form a multi-level system of resource provision for construction projects. Under modern conditions of high market turbulence, rising material costs, logistical constraints, and increasing risks of supply chain disruptions, material and technical support is transforming into a strategic element of a construction enterprise’s competitiveness.

The paper generalizes the evolution of scientific approaches to the interpretation of MTS – from classical concepts of scientific management and mass production to modern logistics and digital models of supply chain management. It is substantiated that key efficiency factors include synchronization of material and production flows, optimization of procurement policy, inventory management based on economic models (EOQ, TCO), flexibility of logistics schemes, supplier diversification, and the level of digital integration of ERP, SCM, and BI analytics systems.

A classification of factors influencing the effectiveness of MTS at a construction enterprise is systematized according to functional groups: production-technological, organizational, financial, infrastructural, informational, and risk-related. It is shown that their comprehensive interaction forms an integral performance effect manifested in cost reduction, downtime minimization, increased inventory turnover, financial stability enhancement, and improved system adaptability to external shocks.

Special attention is paid to the specifics of the construction industry as a project-oriented field characterized by territorial dispersion of facilities, demand instability, and high dependence on resource flows. It is proven that under such conditions, MTS efficiency is achieved through the combination of hybrid logistics models (Push, Pull, Just-in-Time), the implementation of scenario planning, and the development of risk management systems.

The practical significance of the study lies in the possibility of applying the formulated factor-based models to build an adaptive material and technical support system for construction enterprises aimed at cost minimization, increased resource efficiency, and ensured organizational resilience under conditions of market instability.

Structural and analytical description of digital tools for construction project analysis

Andrii SHTYL — 2026-02-26

A structural and analytical understanding of digital tools for construction project analysis acquires particular significance under conditions of intensive digital transformation of the industry. Contemporary construction management is evolving into an integrated information environment that combines Building Information Modeling (BIM) platforms, Enterprise Resource Planning (ERP) systems, Common Data Environments (CDE), and business analytics tools. Their interaction ensures the transition from isolated process automation to comprehensive analytical coordination throughout the entire life cycle of a construction asset.

The functional roles of digital platforms are identified, and their phase dominance is determined depending on the stage of project implementation. BIM forms a parametric model of the facility and provides the basis for visual and analytical assessment; ERP systems coordinate financial and resource flows; CDE ensures consolidation, updating, and traceability of information; analytical tools enable forecasting, scenario modeling, and risk assessment.

The expediency of formalizing the effectiveness of digital platform integration through the use of integral activity indicators, an information flow quality index, and data replication reliability models is substantiated. Configurational types of information architectures (centralized, network-based, linear, and hybrid) are analyzed, and their impact on data latency, analytical accuracy, and consistency levels is determined.

It is emphasized that the modern digital environment of a construction project is acquiring the features of an adaptive system capable of reconfiguration depending on changes in internal and external parameters. Ensuring semantic compatibility, standardization of data exchange formats, and minimization of information redundancy are considered necessary conditions for enhancing manageability.

The integration of digital tools forms the conceptual foundation of predictive and risk-oriented management, in which data function as a strategic resource and a key factor in making well-grounded managerial decisions.

Conceptual structure of the scientific instrumentarium for management decision support

Viktor PYLYPCHUK — 2026-02-26

The formation of a conceptual structure of the scientific instrumentarium for management decision support is a necessary condition for ensuring the systemic coherence, validity, and adaptability of modern management. Under conditions of increasing complexity of socio-economic processes, growth of information flows, and the dynamic nature of the external environment, managerial decisions must rely on integrated analytical mechanisms that combine methodological rigor, procedural consistency, and technological implementation.

The conceptual structure of the instrumentarium is considered as a multi-level system encompassing methodological, procedural, and technological segments. The methodological level defines the principles of model construction, the logic of hypothesis formulation, and the criteria for interpreting results. The procedural level ensures the transformation of primary data into structured analytical scenarios through a sequence of formalized operations. The technological level implements these mechanisms within a digital environment, providing scalability, adaptability, and high-speed information processing.

Special attention is given to the integration of different types of models – deterministic, probabilistic, and cognitive – within a unified analytical framework. Such integration enables the reproduction of both structural dependencies of the system and stochastic fluctuations, as well as cause-and-effect relationships shaping its behavior. The combination of formal mathematical methods with expert interpretation forms the foundation for a hybrid approach to decision-making.

It is substantiated that the effectiveness of the instrumentarium is determined by the structural consistency of its components, the verifiability of procedures, and the capacity for adaptive reconfiguration depending on the type of managerial task. The formalization of information transformation processes through multi-stage functions ensures the logical integrity of the analytical cycle – from data collection to the formation of managerial alternatives.

The role of the technological segment as an integration infrastructure uniting analytical platforms, simulation modules, computational cores, and visualization tools is emphasized. Its scalability and self-configurational capacity determine the overall performance level of the decision support system.

Content-structural characteristics of organizational and managerial decisions in the environment of development projects

Rostyslav PELEKHATYI — 2026-02-26

Organizational and managerial decisions within the environment of development projects constitute a complex multidimensional system of actions integrating economic, legal, social, and technical-technological components throughout the life cycle of a real estate asset. Development, as a form of capital management in the real estate domain, differs from traditional construction by the presence of an extended pre-investment phase, a high degree of institutional dependency, and a significant implementation period. Under such conditions, managerial decisions acquire a systemic character, combining the functions of strategic choice, stakeholder coordination, and risk minimization.

The substantive features of organizational and managerial decisions in development are revealed, encompassing the formation of the project concept, financial structuring, selection of technical solutions, ensuring institutional legitimacy, and integration of social factors. It is established that decisions are formed within a managerial loop that includes problem identification, analytical processing of the situation, development of alternatives, legitimization, and implementation monitoring. This approach ensures adaptability and the possibility of adjusting decisions depending on environmental changes.

The structural components of a decision are defined as follows: the information base, the set of stakeholders, approval procedures, time constraints, mechanisms of influence, and performance evaluation criteria. It is demonstrated that the effectiveness of decisions depends on their ability to integrate financial indicators, risk parameters, social acceptability, and strategic synergy with the urban environment. Particular importance is attached to institutional constraints and ESG principles, which influence investment attractiveness and the long-term sustainability of the project.

A typology of managerial decisions is proposed according to levels (strategic, tactical, operational), functional orientation (investment, technical, social, financial-legal), and temporal characteristics. The expediency of applying system-dynamic and multicriteria approaches to optimize decisions under conditions of uncertainty is substantiated.

The generalization of the results makes it possible to assert that the content-structural characteristics of organizational and managerial decisions in development form the foundation for building an adaptive management model capable of ensuring a balance between economic efficiency, social responsibility, and institutional sustainability of the project.

Digital monitoring toolkit for resource and time parameters under conditions of dynamic project interaction

Dmytro RIZUN — 2026-02-26

The toolkit for digital monitoring of resource and time parameters in construction projects is formed as a multi-level information and analytical system that ensures continuous tracking, forecasting, and adjustment of project dynamics within a changing environment. In contemporary project management practice, monitoring extends beyond the mere recording of actual indicators and transforms into a comprehensive predictive analytics system integrated with BIM, ERP, and IoT digital platforms. Such integration synchronizes spatial models, resource flows, and sensor data received in real time, thereby creating a unified digital management environment.

The study reveals the conceptual foundations for the formation of a digital monitoring toolkit that combines mathematical models of resource depletion, logarithmic assessments of utilization efficiency, integral indicators of productivity losses, and stochastic risk models. The feasibility of applying exponential, logarithmic, and integral functions to formalize the dynamics of resource consumption and the accumulation of time deviations is substantiated. It is demonstrated that the use of multifactor models enables the assessment not only of absolute changes in indicators but also of their sensitivity to external and internal disturbances.

Special attention is given to the functional and analytical interaction of digital platforms. BIM is considered as the spatial and informational basis of monitoring, ERP as the system of resource and financial coordination, and IoT as the sensor layer ensuring data reliability. Their integration forms an adaptive management architecture capable of reconfiguration depending on changes in project parameters.

Within the framework of the research, approaches to forecasting deviations based on probabilistic, stochastic, simulation, and neural network models are systematized. The application of Monte Carlo methods, agent-based modeling, and LSTM architectures enables scenario analysis, assessment of the probability of exceeding critical thresholds, and the generation of early warning signals. This approach transforms monitoring from a reactive function into a proactive instrument of strategic management.

It is concluded that the effectiveness of digital monitoring is determined by the structural coherence of mathematical models, software platforms, and organizational procedures. The integration of analytical mechanisms into a unified coordination system ensures improved resource balance, minimization of time losses, and enhanced project resilience under conditions of uncertainty.

Construction project as a complex multi-level socio-technical system

Roman KOZIUK — 2026-02-26

A construction project is interpreted as a complex multi-level socio-technical system that integrates structural, functional, and process components within a unified management model. Its systemic nature is determined by the multiplicity of stakeholders involved, the multi-channel character of resource and information flows, and its openness to the influence of the external environment. Such an approach makes it possible to consider a construction project not merely as a set of technological operations, but as a dynamic organizational structure capable of adaptation and self-regulation.

The structural dimension of the project encompasses the hierarchy of management levels–strategic, tactical, and operational–as well as the configuration of key participants among whom coordination and responsibility relationships are established. Multi-level organization determines the complexity of authority distribution and the necessity of aligning decisions across management levels. The functional dimension reflects the interaction of financial, technical, logistical, informational, and control subsystems that ensure the implementation of investment and construction objectives. Project effectiveness depends on the degree of their integration and synchronization.

The process dimension characterizes the sequence of life cycle phases–from initiation to completion–and the mechanisms for transforming resources into final results. Planning, implementation, monitoring, and adjustment processes form a closed management loop operating on the basis of feedback. System adaptability is ensured through the use of digital coordination tools, risk management instruments, and scenario analysis. The socio-technical nature of the project is manifested in the interaction between human potential and technological infrastructure. The alignment of social and technical subsystems creates the prerequisites for stable functioning under conditions of uncertainty. The integration of structural, functional, and process characteristics establishes a methodological foundation for enhancing the effectiveness of managing complex investment and construction programs.

Development of a methodology for scientific and technical supervision of the restoration of architectural and urban planning monuments

Anatolii KOVROV — 2026-02-26

Preservation of cultural heritage in the context of urban development and reconstruction requires new approaches to technical control. Traditional methods of technical supervision, focused exclusively on monitoring the compliance of completed works with the requirements of design and estimate documentation and regulatory legal acts, are critically insufficient for cultural heritage sites. Such an approach does not guarantee compliance with international restoration standards and creates a real threat of losing their historical value. The existing organizational model of technical supervision in Ukraine establishes the procedural dependence of the technical supervision engineer and provides for his universal specialization. The systemic lack of professional training in working with historical materials and restoration technologies leads to irreversible losses of the authenticity of architectural and urban planning monuments during repair and restoration works.

The article proposes an author's organizational model of scientific and technical supervision, the fundamental basis of which is the targeted specialization and digitalization of the control of the technical supervision engineer. A methodology has been developed that provides for mandatory specialized training (special training) of an engineer by specialists in scientific and technical support for the specifics of a particular historical object. This approach turns a technical supervision engineer into a qualified guarantor of compliance with ICOMOS principles within the framework of project implementation. The implementation of the methodology allows to effectively bridge the gap between the scientific requirements of restorer scientists and the practical actions of construction contractors. It has been proven that the use of modern digital tools (in particular, the formation of an integrated "digital memory of the object") transforms supervision from the formal signing of paper acts into a transparent process of continuous monitoring. This forms a reliable protective barrier that protects the national cultural capital from incompetent interventions and increases the overall quality of restoration and repair work.

Adaptation of the MODAPTS microelemental regulation system to the conditions of modern monolithic construction

Olena SHANDRA — 2026-02-26

The article examines the problem of standardizing technological processes for the installation of monolithic structures in multi-story frame buildings, stemming from the shortcomings of existing regulatory information sources that utilize an overly generalized (complex) approach to calculating time resources. An analysis of the current technological level of monolithic frame building construction revealed a significant number of structural and technological innovations not covered by current national or international labor cost standards. Furthermore, leading global construction companies do not disclose data regarding the labor intensity of their proprietary developments, creating a challenge in justifying optimal structural and technological solutions (STS) and necessitating the development of new analytical tools.

It is demonstrated that transitioning the time-standardization system from the level of construction operations to the level of worker action complexes, using the MODAPTS micro-element standardization system well-known in mechanical engineering, paves the way for a new, dynamic methodology. This system allows for the evaluation of labor costs for any innovative frame construction technologies, including those currently under development. The specific features of construction production required a revision of the approach to defining the MOD micro-module. Based on the research results, the author's micro-element standardization system "BUDTS" was developed, representing a modification of MODAPTS adapted to construction conditions. The key change is the increase of the basic time unit from 0.129 to 0.25 and 0.5 seconds. Such modules allow for a more accurate accounting of movement inertia and the complexity of manipulating heavy and bulky materials or equipment. The transformation of the system into a "macro-mod" format ensures high-speed standardization during the alternative design of construction technologies for monolithic frame buildings.

Digital model and erp tools for management solutions in construction organization

Vladyslav ZHELEZNIAK — 2026-02-26

The article considers the issue of digital transformation of the organization of construction production in the conditions of increasing dynamism of the implementation of construction projects. The main problems of traditional approaches to the organization of construction, which are based on static organizational and technological models and do not provide the necessary flexibility in the management of production processes, are identified. The feasibility of integrating ERP systems into the process of managing construction projects to support management decision-making is substantiated. A conceptual model of digital support of organizational and technological decisions in construction is proposed, which is based on the interaction of production processes, resource provision, time parameters and project implementation conditions. It is shown that the use of ERP tools allows for the prompt restructuring of organizational decisions when changing the conditions of work. Thus, the proposed conceptual model demonstrates that the integration of ERP systems into the construction management process ensures the formation of a digital environment for making management decisions, which allows increasing the adaptability of the organizational and technological system of construction and ensuring the stability of the implementation of construction projects in changing conditions.

The results of testing the approach on practical construction sites are presented, confirming the possibility of reducing resource downtime, increasing the uniformity of work performance and reducing deviations from calendar schedules. The results of the study showed that the digital transformation of construction organization is an important condition for increasing the efficiency of construction project implementation. The results obtained can be used in the development of integrated construction management information systems, the formation of organizational solutions and the improvement of construction project management practices.

Formation of digital toolkit for construction organization project

Roman KONONCHUK — 2026-02-26

The article considers the formation of a scientific and applied toolkit for a digital construction organization project in the context of digital transformation of the construction industry. It has been established that traditional organizational and technological approaches to construction production management do not provide sufficient adaptability to changes in resource provision and do not integrate information flows into a single management system. A conceptual approach to the formation of a digital construction organization project is proposed, which is based on the integration of the object information model, calendar and resource planning, monitoring system and analytical management within a single digital environment. Thanks to the integration of information flows in the digital environment, management is carried out in a mode of continuous control and adaptation to changes in the conditions of construction project implementation.

A conceptual model of a digital project of a construction organization is presented, which demonstrates the integration of information, organizational-technological and management processes within a single digital environment of construction production management. The central element of the presented model is a single digital platform of construction management, which ensures the integration of information flows between all participants in the construction process. The proposed model structure is based on a systemic approach to construction organization and involves a combination of digital modeling, calendar-resource planning, monitoring of work performance and analytical management in a single information platform. An organizational-technological model of digital construction production management and mathematical formalization of the integral indicator of project implementation efficiency have been developed. Practical testing of the proposed approach has shown the possibility of increasing the efficiency of construction project implementation by optimizing calendar-resource parameters and promptly responding to changes in the resource environment.

Improvement of the organization of the complete set of products and structures of industrial buildings

Oleg ZINKOV — 2026-02-26

The article considers the problems of organizing the assembly of prefabricated reinforced concrete structures during the construction of industrial buildings. It has been established that the efficiency of the assembly of prefabricated structures is largely determined by the organizational coherence of the processes of supply, transportation and installation of structural elements. These problems are especially acute during the construction of industrial buildings, where the assembly of structures is carried out in a short time and requires a high level of coordination between manufacturers of structures, transport organizations and installation units. In this regard, improving organizational and technological solutions for the assembly of prefabricated reinforced concrete structures is an important direction for increasing the efficiency of construction production.

As a result of the study of construction production processes, an organizational and technological model was proposed that reflects the system structure of the process of completing prefabricated reinforced concrete structures during the construction of industrial buildings. The considered model involves the integration of three key functional subsystems of the construction process: production of structures, logistics and installation work. The interaction of the specified subsystems is implemented through the coordination and technological control unit, which ensures synchronization of information and production processes within the framework of the construction project.

Modern scientific approaches to the organization of construction production are analyzed and the main shortcomings of traditional schemes for the assembly of structures are identified. An organizational and technological model for optimizing the assembly processes of prefabricated reinforced concrete structures is proposed, taking into account the logistical, time and resource parameters of construction. A methodological approach to increasing the efficiency of the installation of industrial buildings by coordinating supply schedules and performing installation work has been developed. The results obtained can be used in the development of organizational and technological documentation for the construction of industrial facilities.

Digital toolkit for development project implementation

Oleksandr KOBELCHUK — 2026-02-26

The article considers the issue of forming a scientific and applied toolkit for a digital development project in the context of the transformation of the construction industry. It is established that traditional organizational and technological approaches to managing the implementation of construction projects do not provide the proper level of integration of information flows, which leads to deviations from the planned deadlines and construction costs. A conceptual approach to forming a digital toolkit for managing development projects is proposed, which is based on the integration of calendar planning, resource provision, cost estimates and monitoring of work performance in a single information environment.

A model of a scientific and applied toolkit for a digital development project has been developed, reflecting the system structure of integrated management of the implementation of a construction project in the context of the digital transformation of the industry. Within the framework of this model, a development project is considered as a complex organizational and technological system that functions in the interaction of several subsystems: information, organizational, resource and management. Their integration is ensured through a single digital project management environment that combines planning, execution and control of construction processes.

One of the structural components of the proposed toolkit is the information model of the construction project, which is formed on the basis of digital data management technologies. In modern practice, it is implemented through the use of BIM models, digital calendar schedules, resource plans and financial models of the project. The information model plays the role of an integrating element of management, as it ensures the accumulation and updating of data on construction parameters at all stages of the life cycle of the object. This creates a single information base that is used by all participants in the development project.

An organizational and technological model of digitally integrated management has been developed, which ensures the coordination of time, cost, resource and information status parameters of the project. The proposed approach has been tested on a real construction site, which confirmed the possibility of increasing the integral indicator of the effectiveness of the project implementation.

Formation of a structural model for determining the duration of construction in the conditions of an energy crisis

Valerii OLIINYK — 2026-02-26

The article is aimed at solving the current scientific and applied problem of determining and optimizing the duration of construction in conditions of unstable resource supply and energy crisis. Modern conditions of the construction industry are characterized by a high level of uncertainty, which is due to the combined effect of military, economic, energy and logistical factors. As a result, there is a disruption in the rhythm of construction work, an increase in the share of unfinished construction, an increase in deviations between the planned and actual terms of implementation of investment and construction projects. The traditional organizational and technological methods for determining the duration of construction, which are based on the assumption of the stability of resource supply, do not provide the necessary accuracy of forecasting and efficiency of construction process management, are considered.

The structural model of the author's scientific and applied toolkit for determining the duration of construction in the conditions of the energy crisis is formed, it is a holistic system of interconnected blocks that ensure a consistent transition from the analysis of initial conditions to the formation and optimization of organizational and technological solutions. It is this structure that creates the basis for further formalization of the algorithms of the toolkit and their practical testing.

The study of the materials of the article is determined by the need to transition to adaptive models of construction duration management, which take into account the instability of the resource environment, the irregularity of work performance, periodic restrictions on energy supply and the variability of the availability of labor and material and technical resources. The article substantiates that in the conditions of the energy crisis, the duration of construction should be considered not as a fixed result of the calculation, but as a controllable parameter that is formed in the process of making organizational and technological decisions.

Features of formation of analytical structure of risk assessment of real estate projects in the conditions of external changes

Іgor DVORNICHEN — 2026-02-26

Modern economic development is characterized by a high level of dynamism, increasing uncertainty of the external environment, accelerating transformation of market conditions and increasing the level of risks of implementing investment projects. These trends are especially acute in the field of development and implementation of investment and construction projects, which are characterized by high capital intensity, significant duration of implementation, complex financing structure and a large number of stakeholders.

In modern conditions, development projects operate in an environment where macroeconomic, market, regulatory, resource and technological factors are simultaneously affected. High volatility of the cost of construction resources, changes in financing conditions, fluctuations in demand in the real estate market and the rapid development of digital technologies significantly complicate the process of managing development projects.

Traditional approaches to managing development projects, which are based on static planning models and rigidly fixed forecast indicators, do not provide the necessary level of management adaptability. As a result, there is a need to develop integrated adaptive models of optimizing management decisions that can ensure effective management of development projects in conditions of rapid changes in the external environment.

The developed structure for implementing an optimized management decision reflects the logic of the transition from the results of analytical optimization to practical management of a development project in conditions of rapid changes in the external environment. Unlike traditional approaches to managing investment and construction projects, in which making a management decision is considered as the final stage of the analytical process, in the proposed author's approach, the management decision is only the initial phase of a continuous management cycle, which includes implementation, monitoring and adaptive adjustment of project parameters.

Within the author's concept of managing development projects in conditions of rapid change, the management decision is considered as a dynamic management structure, which is formed on the basis of the integration of scenario analysis, risk assessment and multi-criteria optimization, but is not a static result of analytical activity.

Analysis of the efficiency of semi-precast lightweight composite floor slab installation technology

Hennadii TONKACHEIEV — 2026-02-26

The article is devoted to the analysis of the BubbleDeck technology as an innovative solution for lightweight floor slabs in the construction of multi-story frame buildings, as well as the justification of its applicability in comparison with the monolithic Cobiax system. The use of void-formers allows reducing the dead weight of slabs by 20–40% and cutting concrete consumption by up to 40% without compromising load-bearing capacity. However, the economic feasibility of a particular system is determined not only by structural parameters but also by the presence of specialized precast concrete plants in the construction region. The European experience in the application of lightweight floor slabs is examined, specifically the Cobiax company as a leader in the monolithic segment, and the Danish company BubbleDeck as the pioneer in offering precast-monolithic bidirectional slabs with integrated void-formers.

The structural features of the BubbleDeck system are analyzed. The slab has a two-layer structure consisting of a 60 mm precast bottom layer with factory-installed spherical void-formers and a monolithic top layer made of high-strength lightweight concrete (LC40). The system is designed for spans of 7.2–8.4 m, with slab thicknesses ranging from 230 to 600 mm. As a representative of the monolithic segment, the Cobiax system with ellipsoid inserts for spans of 6.0–8.4 m is considered.

Differences between the systems in terms of formwork, reinforcement, and labor intensity of installation are analyzed. The factory readiness of BubbleDeck slabs eliminates the need for solid plywood formwork – linear supports are sufficient. Factory-controlled reinforcement and ball spacing minimize the risk of void-former buoyancy during concreting, which remains a relevant problem for monolithic options. The bottom surface of the slab turns out to be smooth, requiring no plastering. The installation of a single panel with an area of up to 20–30 m² is faster than the assembly and disassembly of formwork for monolithic options, allowing for a construction pace of one floor per week. At the same time, high factory readiness generates new costs associated with the transportation of large-sized elements, rigging, crane lifting, and precise positioning of panels at the site. The transport component per 1 m² increases in proportion to the distance, and at a distance of over 150 km, it becomes comparable to the savings achieved on formwork operations.

Ways of integrating technical supervision into the building information modeling environment for the transition to automated scientific and technical support

Ruslan ZHALDAK — 2026-02-26

The integration of technical supervision into the Building Information Modeling (BIM) environment represents a key direction in transforming construction project management systems under conditions of industry digitalization. Modern approaches to organizing construction production require increased transparency, efficiency, and reliability of quality control, which necessitates the transition to automated forms of scientific and technical support. In this context, BIM technologies create the prerequisites for integrating technical supervision into a unified digital information environment, ensuring continuous data exchange among all participants in the construction process.

The essence of technical supervision is considered as a component of the system of quality control and management in construction, aimed at ensuring compliance of executed works with design solutions, regulatory requirements, and standards. It is determined that traditional methods of technical supervision have limited effectiveness due to fragmented information, delays in data processing, and the lack of integrated digital tools. The implementation of BIM makes it possible to overcome these limitations by creating a unified information space in which data on the condition of the construction object is updated in real time.

The directions of integrating technical supervision into the BIM environment are substantiated, including: the use of digital models to verify the compliance of completed works with design parameters; the application of automated monitoring and deviation analysis tools; the implementation of data collection and processing systems based on sensor technologies; and the integration of information and analytical platforms to support managerial decision-making. Particular attention is paid to the use of automated verification algorithms, digital twins, and cloud services to ensure continuous control of construction processes.

The potential for integrating BIM with automated monitoring systems, the Internet of Things (IoT), and big data analytics tools is also of significant importance, enabling continuous tracking of construction process parameters in real time. This creates the basis for implementing preventive control, which relies on forecasting potential deviations and timely response to them.

Research and substitution of rational organizational and technological models of installation of window structures

Dmytro FIRSOV — 2026-02-26

Construction production is characterized by a high level of social division of labor, the complexity of construction objects, a large number of options for technology and organization, specialization and cooperation, and other factors. This leads to a multiplicity of options for solving construction planning and management problems. When developing construction organization plans, it is necessary to compare a large number of possible alternative solutions and choose the most correct ones from them. This process significantly accelerates the use of effective technological models of construction, as well as other project documents. Technologies in the construction industry of Ukraine are developing due to the introduction of innovative approaches. A significant increase in construction volumes and growing demand for residential buildings also affects the volume of installation work of window structures, which accordingly requires scientific justification of possible directions for improving the technological process. The study is devoted to solving an important scientific and practical problem, which consists in creating and implementing organizational and technological models of construction. Such models are designed to ensure a high level of energy efficiency of construction objects at all stages of their life cycle. The main goal is to develop methodological principles for integrated management of construction processes, which allows for the effective use of material, labor and energy resources, reduce operating costs, and increase the technological productivity of construction works. Research and justification and selection of rational organizational and technological models for the installation of window structures is based on the principle of phased synthesis of solutions, which takes into account the system of influencing factors and installation conditions and ensures high-performance implementation of the complex of construction and installation works of the entire building. The organizational and technological modeling of the installation of window structures is based on a systematic approach that takes into account technical, technological and organizational relationships during the installation of window structures. The comprehensive implementation of these organizational and technological measures ensures increased energy efficiency of buildings, reduced operating costs, and rational use of resources both during the construction process and throughout the subsequent operation of the facilities.

Research methodology and substantiation of methods and solutions for the application of pvc windows in architectural monuments

Mykola BONDARENKO — 2026-02-26

The use of polyvinyl chloride (PVC) windows in architectural monuments has been actively debated over recent decades, particularly in Western European countries. Germany, Austria, and other countries place special emphasis on the restoration of architectural heritage. The traditional approach to restoration is based on the use of materials that were originally employed at the time of the monument’s construction. However, in recent years, there has been a growing tendency to consider the use of modern materials in order to preserve and extend the lifespan of heritage objects.

The decision-making process regarding the application of PVC windows in architectural monuments occurs in several stages and is based on numerous factors. A particularly important stage in this process is the formation of a system of methods and solutions aimed at optimally addressing restoration tasks while ensuring the preservation of the object. It should be noted that the research methodology serves as a fundamental prerequisite for substantiating the methods and solutions for the use of PVC windows. It enables the systematization and generalization of construction and technological characteristics of the object based on system-forming features that describe both the overall value of the architectural monument and its individual elements, including window and door structures, which are among the most frequently replaced components throughout the lifecycle of the building.

The result of systematizing these system-forming features should be the development of a structured set of methods and solutions for the application of PVC windows. These methods and solutions must ensure the integrity of window systems through repair or complete replacement, improve the energy efficiency of the building, and enhance the overall preservation of the architectural monument.

Based on these objectives and through organizational and technological modeling, a set of rational methods and solutions should be developed to ensure the proper organization of construction and technological processes, account for organizational constraints, and define interrelationships. The outcome of such modeling should be the selection of an optimal system for the application of PVC windows and doors in architectural monuments.

Analysis of the chemical composition and main sources of wastewater formation that occur in the process of chemical water preparation at heat power plants

Oleksiy TERNOVTSEV — 2026-02-26

The article, based on the analysis of literary and other sources, as well as laboratory studies of the chemical composition of water, provides an analysis of the chemical composition and main sources of wastewater formation obtained in the process of chemical water treatment at some heat and power enterprises. Wastewater from heat and power industries, in particular from chemical water treatment plants, contains a significant amount of salts, suspended solids and other mineral and sometimes organic impurities. Such water is usually discharged into the sewerage network and water bodies almost without treatment.

The main volume of chemically contaminated wastewater formed in the process of chemical water treatment is wastewater from ion-exchange softening and desalination plants. Environmental protection from wastewater pollution and rational use of water resources are one of the most important tasks. To solve this problem, closed water supply systems of industrial enterprises are gaining more and more attention, which completely exclude the discharge of wastewater into water bodies (non-drainage systems).

The creation of closed, and especially drainless, environmentally friendly return water supply systems for heat and power enterprises is a very urgent task for both Ukraine and other countries experiencing a shortage of fresh water.

The article provides up-to-date initial data on the sources of formation and quality of wastewater from energy and power-generating facilities for future development and implementation of methods and technological solutions during the reconstruction or design of such enterprises. The development of new methods for the regeneration of solutions will reduce the financial costs of regenerating ion-exchange filters, significantly increase the volume of water in a closed cycle and approach the creation of a drainless enterprise. In this way, it is possible to improve the ecological situation in the area of the enterprise that uses a closed drainless recycling scheme.

New urbanism of reconstruction in a post-conflict environment: paradigms and principles of restoring the architectural fund destroyed as a result of the Russian-Ukrainian war

Liubov LEPSKA — 2026-02-26

Conflict-affected cities, particularly those in Ukraine, face long-term challenges associated not only with the consequences of war but also with the need for sustainable and integrated reconstruction. The complexity of recovery processes has expanded beyond traditional issues of post-war restoration, preservation of urban heritage, and rebuilding of iconic elements of the built environment to include challenges related to decision-making efficiency, resource management, technological implementation, and financing mechanisms. These factors often lead to prolonged reconstruction cycles lacking coherent long-term planning and management. The full-scale Russian-Ukrainian war has resulted in extensive destruction of residential, public, and industrial facilities, making the prompt, high-quality, and resource-efficient restoration of infrastructure and architectural heritage a national priority. Modern reconstruction strategies increasingly rely on digital and innovative technologies, including BIM, GIS, artificial intelligence, digital twins, and additive manufacturing. However, reconstruction planning focused exclusively on urgent functional needs often leads to the neglect of New Urbanism principles, resulting in fragmented urban environments and the formation of disconnected spatial structures. This article aims to systematize global and Ukrainian paradigms, practices, and case studies of post-conflict reconstruction of destroyed architectural assets within the framework of New Urbanism principles. The methodological basis of the research includes comparative analysis of international reconstruction cases, synthesis of technological and urban planning approaches, and generalization of decision-making models applied in post-war recovery. Particular attention is given to the integration of digital technologies into sustainable urban redevelopment strategies and the preservation of urban identity. The results highlight the importance of aligning technological reconstruction processes with holistic urban development concepts, emphasizing walkability, mixed-use planning, community participation, and environmental sustainability. The proposed conceptual approach contributes to the formation of a resilient and adaptive reconstruction paradigm suitable for the restoration of Ukrainian cities affected by military aggression.

Quantitative assessment of the impact of complicating factors on the labor intensity of technical supervision

Oleksii TUHAI — 2026-02-26

The article considers an urgent problem in modern construction practice, where the implementation of investment projects increasingly occurs in non-standard conditions under the influence of a significant number of complicating factors. It is noted that these factors directly affect not only the technology of executing works but also the process of carrying out control and supervisory procedures by the Customer. It is proven that although the existing regulatory framework governs the impact of such conditions on the estimated cost, it ignores the increase in the labor intensity of engineering personnel. Consequently, the lack of an objective quantitative assessment makes the rational standardization of the technical supervision service's labor impossible. Given this, the aim of the study is to substantiate the methodology for the quantitative assessment of the impact of complicating factors on the labor intensity of engineering personnel to form a mathematical apparatus for standardizing labor costs. During the study, 7 of the most significant factors that prevalently affect technical supervision were distinguished from the general array: the frequency of project changes, the level of implementation of innovative technologies, labor intensity, the overall risk level, the structural complexity of the project, the required level of expertise, and the duration of construction. Based on these parameters, a mathematical model for calculating the integral technical supervision complexity index is proposed, relying on weight coefficients and a scoring assessment of the factors. The practical effectiveness of the approach is confirmed by calculating the index for a project involving the installation of a flat membrane roof with integrated solar panels. It is summarized that the calculated integral index is a determining factor in managing production processes, allowing for the efficient allocation of engineering service resources. It is proven that the increasing complexity of projects requires a transition to structural information management and interaction with the digital environment to verify supervisory procedures.

Formation of flow methods for organizing work in the construction of low-rise residential construction

Maksym KLYS — 2026-02-26

The article examines theoretical and practical aspects of the formation of flow-based methods for organizing construction processes in the development of low-rise residential buildings. The relevance of the research is determined by the increasing demand for residential infrastructure, particularly in the context of Ukraine’s post-war reconstruction, as well as the need to improve the efficiency of resource utilization in the construction industry. Traditional approaches to construction organization often fail to ensure the necessary rhythm and continuity of technological operations, which leads to uneven use of labor resources, increased project duration, and higher construction costs. In this context, the implementation of flow-based organizational methods becomes an effective tool for improving the productivity and efficiency of construction processes.

The aim of the study is to develop and scientifically substantiate an integrated approach to the formation of flow methods for organizing construction work during the development of low-rise residential buildings while ensuring compliance with modern energy efficiency standards and rational use of resources. The research methodology includes system analysis, comparative analysis of construction organization models, mathematical modeling of construction flows, and the application of modern management methodologies used in construction production.

The study analyzes the main models of construction organization, including linear, flow-based, cyclical, and modular approaches, and evaluates their advantages and limitations in the context of low-rise residential development. Particular attention is paid to the mathematical modeling of construction flow parameters, including the determination of deployment and folding periods of flows, which makes it possible to optimize construction schedules and improve the utilization of labor resources without increasing workforce involvement.

An organizational and technological model for the linear-flow construction of low-rise residential buildings is proposed. The model is based on the principles of serial construction, takt planning, and the division of the work front into construction zones, enabling better coordination of construction teams and reducing idle time between operations. The study also considers the application of innovative construction materials and technologies that facilitate faster installation processes and improve construction efficiency.

Information technologies in the management of configuration and logistics of prefabricated housing construction

Oleksandr OSIPOV — 2026-02-26

The article investigates modern approaches to the application of information technologies in the management of configuration and logistics in prefabricated housing construction. The relevance of the research is determined by the rapid urbanization processes, the growing global demand for affordable housing, and the need to significantly reduce construction project implementation time. Traditional methods of construction management are often characterized by insufficient coordination of material, informational, and transport flows, which leads to delays in supply chains, inefficient use of resources, and reduced productivity of construction processes. In this context, the digital transformation of logistics and supply management becomes an essential prerequisite for improving the efficiency of prefabricated and modular construction systems.

The aim of the study is to analyze the potential and effectiveness of modern information technologies, including Building Information Modeling (BIM), the Internet of Things (IoT), cloud computing, and intelligent supply chain management systems, in optimizing logistics and configuration processes in prefabricated residential construction. The research is based on a comprehensive methodological framework that includes system analysis, mathematical modeling, comparative analysis, and optimization techniques. In particular, a dual-objective optimization model considering carbon emissions and customer satisfaction indicators was applied to analyze logistics processes. The optimization problem was solved using an improved Non-dominated Sorting Genetic Algorithm (NSGA-II). Additionally, simulation modeling of modular assembly processes was conducted using the Visual Components 3D environment.

The results of the study demonstrate that the implementation of digital technologies significantly improves the efficiency of logistics management in construction projects. A comparative analysis of manual and automated assembly processes revealed that robotic production lines can reduce the duration of modular assembly operations by approximately 35–38%. Economic calculations confirm the high investment efficiency of automated prefabrication technologies, with relatively short payback periods due to substantial labor cost savings.

The study also identifies the key barriers that hinder the widespread implementation of digital technologies in prefabricated construction. These barriers include high initial investment costs, technological challenges related to the integration of information systems, insufficient digital competencies among construction professionals, and regulatory constraints within existing construction standards. To address these challenges, methodological approaches based on process-oriented life cycle management and the integration of CAD–BIM–CAM systems are proposed.

The impact of the sequence of structures delivery on the intensity of construction of low-rise prefabricated buildings

Volodymyr RASHKIVSKYI — 2026-02-26

In modern construction, prefabricated and modular building methods are gaining increasing popularity due to their ability to significantly reduce project timelines, minimize waste, and improve overall construction quality. This article is devoted to investigating a critical aspect of construction management – the impact of the delivery sequence of prefabricated structures (panels, modules, frame elements) on the intensity of assembling low-rise prefabricated buildings. The logistical problems faced by construction companies are considered, in particular, the complexity of transporting large-sized elements, the limited storage area on the construction site, and the need for strict synchronization of production and assembly processes. Special attention is paid to the implementation of Lean Logistics principles and the "Just-in-Time" (JIT) concept, which allow for "wheels-to-structure" assembly, thereby avoiding the downtime of assembly cranes and construction crews.

In this work, a mathematical model for the comprehensive assessment of the compatibility of supply and assembly processes was developed and adapted, taking into account the costs of materials, transportation, as well as penalties for premature or delayed delivery of structures. Based on the calculations and simulated scenarios (unsynchronized supply compared to JIT logistics), it was proven that strict adherence to the sequence of structural delivery can increase the intensity of construction work, reduce total costs, and lower the risks of disrupting calendar schedules. The article contains detailed comparative analyses of traditional logistics versus optimized supply, as well as descriptive graphical interpretations of the relationships between supply accuracy and the technological efficiency of the project. The research results serve as a valuable resource for engineers, project managers, and logisticians aiming to optimize supply chains in prefabricated construction.

Modeling of construction quality parameters on the example of painting work

Oleksandr FILIPPOV — 2026-02-26

The article considers the scientific and practical problem of modeling construction quality parameters on the example of painting work as one of the key components of the finishing cycle during the overhaul of buildings and structures. The quality of painting work largely determines not only the aesthetic characteristics of surfaces, but also the durability, operational stability and protective properties of structures, which necessitates the formalization of factors that affect the final result. The paper substantiates the relevance of using regression and analytical modeling to assess technological labor intensity and determine the relationships between material consumption, labor costs and technological quality parameters. The applied approaches made it possible to identify characteristic patterns of labor intensity changes depending on the amount of materials used in different production conditions – during internal, external and facade painting work.Based on statistical processing and modeling, regression relationships were constructed that reflect the degree of influence of key technological parameters on the probability of quality deviations. It was proven that the labor intensity of the process is nonlinear and forms three distinct risk zones: the area of insufficient labor costs, which is accompanied by an increased probability of defects; the optimal interval of labor intensity, in which maximum stability of technological operations is ensured; and the area of excessive labor costs, which indicates a deterioration in the organization of work and a potential decrease in quality. For each group of painting works, the level of influence of material intensity on the formation of labor loads was determined and it was shown that internal works are characterized by the most predictable parameters, while facade works are most sensitive to the influence of external factors.The results of the study are of important practical importance, since they form methodological prerequisites for creating effective models for predicting the quality of finishing processes and for improving the system of labor cost rationing. The proposed approach helps to increase the accuracy of resource planning, identify critical deviations, optimize organizational and technological solutions and ensure a sustainable level of quality during painting work in construction. The presented results can be used in the practice of designing, performing and monitoring construction work, as well as serve as the basis for the further development of integrated digital quality management models in the construction industry.

Justification of energy efficiency indicators in the energy management system of construction production

Ihor ONOFRIICHUK — 2026-02-26

The article solves a scientific and applied problem of forming organizational and economic tools for evaluating the efficiency of construction production energy management. Given the dominance of the resource-based pricing method, the justification of energy efficiency requires an in-depth analysis of the current resource consumption standards. Since the vast majority of energy consumption on a construction site is accumulated in the process of mechanized vertical movement of loads, the focus of the study is directed at the operational resource intensity of lifting mechanisms. It is proved that relevant energy efficiency indicators should cover not only direct energy carrier costs for the immediate operation of equipment but also associated overhead costs caused by additional labor costs for the management, relocation, and maintenance of mechanization means.

The methodological basis of the research is the translation of statistical analysis methods, econometric modeling, and the theory of “soft computing” into the field of construction economics. Based on the dataset of resource estimating standards for the operation of construction machines and mechanisms, two aggregated samples are analyzed: diesel-engine cranes and electrically driven cranes. Using sample Student's t-tests, statistically significant differences in their operational parameters are empirically confirmed, in particular, total labor costs, needs for fuels and lubricants, and salary-coefficients of labor costs.

The scientific novelty of the research is the development of statistical-econometric two-factor multiplicative models that formalize the nonlinear power-law dependence of the maximum lifting capacity of cranes on the volumes of labor and energy carrier costs. It is established that for diesel cranes, the economies of scale act classically: the replacement of equipment with more powerful ones causes a slowdown in the growth of fuel costs and associated organizational costs. Instead, a diametrically opposite pattern was revealed for electric cranes: the intensification of their capacity causes an accelerated growth in the labor costs of the maintenance team, which exponentially increases energy consumption for general production purposes.

To implement the obtained models into the management contour of a construction enterprise, an author's approach based on the fuzzy set theory is proposed. Interval estimates of the degree of cost growth or savings are developed in the form of parameters of type-2 fuzzy numbers, which compensate for the stochasticity of deviations of actual data from theoretical ones. A graphical-analytical toolset is proposed for making predictive management decisions regarding the optimization of lease relations, the choice of construction equipment, and the identification of hidden resource-saving reserves during the implementation of construction contracts.

Toolkit for stabilizing the financial and economic state of construction participants in cyclical fluctuations

Olha BIELIENKOVA — 2026-02-26

The article examines the issues of forming and implementing a system of anti-cyclical measures to stabilize the financial and economic state of construction participants in conditions of cyclical fluctuations in the economy. It is substantiated that the construction industry is one of the most vulnerable sectors of the economy, as it combines significant capital intensity, a long investment and production cycle and high dependence on the macroeconomic environment. This necessitates the development of a systemic approach to managing financial and economic stability both at the level of construction enterprises and at the level of individual investment and construction projects.The paper proves the feasibility of a hierarchical approach to anti-cyclical management, which involves coordinating strategic decisions at the enterprise level with operational measures implemented within specific projects. At the level of a construction enterprise, anti-cyclical measures are considered as an element of financial, investment and risk policy aimed at maintaining solvency, liquidity, financial balance and optimization of the project portfolio in accordance with the phases of the economic cycle. At the level of an investment and construction project, these measures are specified in the form of cash flow management, control of the estimated cost, minimization of project risks, ensuring calendar and network stability and maintaining investment attractiveness.A logical model of coordination of anti-cyclical measures is proposed according to the principle of "investment and construction project → construction enterprise", which is based on the vertical integration of management decisions and the presence of feedback information links. Such a model allows for timely adjustment of project implementation parameters and the structure of the enterprise's portfolio depending on changes in the external economic environment, reducing the likelihood of accumulation of financial risks and preventing crisis phenomena in the activities of construction participants.The implementation of a coordinated system of anti-cyclical measures contributes to increasing the adaptability of investment and construction activities, reducing the negative impact of economic downturns and creating the prerequisites for ensuring financial stability and sustainable development of construction enterprises in conditions of economic instability.

Integration of development, design, construction and facility management in life cycle management of a construction project

Ihor POLTAVETS — 2026-02-26

The article examines the issue of improving the management of development construction projects based on an integrated approach to their life cycle management. It is substantiated that the traditional practice of fragmented management of individual stages – developmentt, design, construction and operation – does not ensure the achievement of the developer’s long-term goals, leads to an increase in total life cycle costs, increased risks and loss of investment attractiveness of real estate objects.The purpose of the article is to substantiate an integrated approach to life cycle management of a development construction project, which ensures the coordination of management decisions at all key stages of project implementation, taking into account the requirements of further operation. Within the framework of the study, the development project is considered as an integrated socio-economic and technical-management system focused on the formation of the long-term value of a real estate asset.The article analyzes modern scientific approaches to the management of the life cycle of construction objects, the role of the developer as an integrator of processes and stakeholders, as well as the importance of early involvement of the facility management function in the process of making management decisions. It is proven that taking into account operational requirements at the concept and design stages allows optimizing the cost of the life cycle, improving the quality of design and construction solutions, ensuring maintainability, energy efficiency and adaptability of the object to changing market conditions.Particular attention is paid to the justification of the integration of building information modeling (BIM), life cycle cost analysis approaches and facility management principles into a single development project management system. A conceptual vision of integrated management is proposed, aimed at ensuring managerial and information continuity between the stages of the life cycle of a real estate object.The practical significance of the results obtained lies in the possibility of their use by development companies to increase the efficiency of investment decisions, reduce operating costs and form competitive, sustainable and long-term attractive construction projects.
