This study evaluates the impact of Digital Twin (DT) technology on project success metrics—specifically time, cost, quality, and safety—within the automated monitoring and control of construction projects. Employing a mixed-methods approach, the research integrates survey data, Structural Equation Modeling (SEM), case analysis, and qualitative insights from interviews and focus groups. A novel DT-based Progress Monitoring Management Model (DRX) is proposed and assessed, leveraging reality capture and Extended Reality (XR) technologies to streamline construction oversight. Findings reveal that DT significantly improves project outcomes by automating process oversight. The DRX model emerges as an innovative framework, enhancing construction management through the integration of DT and XR technologies, offering empirical insights into its efficacy and delineating its practical challenges and advantages.

The decision-making process is critical to the success of any construction project, construction personnel make decisions related to their duties every day and justify these decisions. Wrong decisions can disrupt the project in terms of time, quality, cost and relationships and can even impose exorbitant costs. On the other hand, design, engineering and construction include complex decisions with high uncertainty, so special attention should be paid to this part. The main goal of this research is to determine the dominant model of the decision-making process of experts in construction projects. In the first step, decision-making models will be identified through library studies, and then their decision-making processes will be determined by attending construction workshops and interviewing experts in the field of construction. In the next step, by communicating between the decision-making processes of experts and decision-making models, the most used model is determined through coding؛ In this research, based on the conducted research, the 3 dominant models used in the decision-making process of expert project managers are: the contingency model, the multi-criteria decision-making model, and the classic model.

In general, any type of accident, occupational disease, or environmental damage inflicts enormous and sometimes irreparable damage directly and indirectly on organizations. The mentioned method is an integrated system that tries to create a healthy, pleasant, lively environment away from accidents with convergence, unifying arrangement of manpower, facilities and equipment, and can be observed by observing its plans in the Health and Wellness Organization of Manpower. , Provided protection against hazards and a healthy environment in the workplace, thus reducing existing risks.Slowness and lack of progress in the implementation of construction projects leads to the lack of sustainable project management, which indicates the existence of obstacles and root problems in the implementation of valuable urban projects that seriously threaten reconstruction and development and can be considered as a crisis of construction projects. named. The main problem that most large projects face is delays in various phases and eventual completion of the project. A delay is an action or event that extends the time specified in the contract to perform a particular action. Various officials and experts must be spent in order to successfully implement such projects within the specified time frame. Because in terms of scientific status and value, according to project management characteristics and factors. Affecting the success of projects, achieving one's time goals. One of the most important indicators of success is the direct relationship between the weakness of safety culture and the increase in the rate of accidents and human, economic and environmental damage has been proven in many similar studies. In addition, in recent years, following the occurrence of numerous accidents, the emphasis has been on creating a positive safety culture, increasing the level of training received, more experiences of accidents and hazards in the workplace, as well as gaining better job positions and therefore safer. . Also, the direct relationship between education level and safety culture score has been emphasized in many studies. Organizations have experienced increasing growth.

Project management is closely related to systems approaches, especially systems engineering systems approach when in the 90s in the defense and armed forces, operations research, systems engineering and project management were used to manage large research and development projects. Project management and systems thinking overlap. Interestingly, it seems that simple systems thinking tools are not widely used in project management, even though these tools can provide unparalleled benefits in framing and solving problems that arise from multiple perspectives and relationships between variables. The main goal of this article is to introduce the concepts and selected tools of systems thinking in project management and describe their application in managing complex projects. Also, the benefits of using "hard" and "soft" systems thinking tools in certain phases of the project life will be discussed.

There are serious concerns about the environmental risks of industrial states activities affecting the life quality of occupants living in the neighbor cities and areas. This research aims at managing and reducing the environmental effects of pollutants, induced by the activities of industrial states (e.g. Kowsar state), on the life quality of neighbor cities occupants (here: Karaj city). There are currently 59 active industrial units in Kowsar state, that are producing commercial products in various sectors such as: chemical, food, metallic, mineral, cellulosic, and electrical industries. To determine the pollution pattern and influence ranking of its environmental pollutants, the current condition of the state and city were studied. Then, the impacts of its environmental pollutants were examined. To collect the required research data, two questionnaires were designed. The first questionnaire was filled out by experts adopted from construction and environmental engineering sectors, and then analyzed using the Delphi method. This resulted in eliminating the unimportant factors from the questionnaire. Accordingly, the second (refined) questionnaire was created, and again completed by research experts. The new data were analyzed using the WASPAS method. The results showed that the highest impact of the industrial state is on the ‘life quality of its own personnel’. This item was followed by items of ‘life disruption of neighbor occupants’, ‘permeation of malodorous aroma in the area’, ‘spread of noise pollution’, and, ‘release of toxic gases’ respectively. Some recommendations for better managing the problem are presented here.

This article provides a comprehensive review of project planning and elucidates its pivotal role in ensuring success in the complex landscape of civil engineering projects. From various perspectives, the emphasis is placed on the sequential progress of projects, precise planning, resource coordination, meticulous control, and the adoption of innovative planning methods as essential components. The consequences of neglecting these fundamental stages, with a focus on cost, time, and project quality factors, are examined. Consequently, the synthesis of these perspectives underscores the linchpin role of planning in construction projects. Sequential progress, coupled with strategic planning and precise control, emerges as a foundational principle. Decision-making based on data and the utilization of mature models enhance project management efficiency. Serving as a comprehensive guide, this article underscores the significance of planning stages as the axis of success in civil engineering projects. With a comprehensive approach, recognition of interdisciplinary nature, and laying the groundwork for informed and strategic decision-making in the dynamic landscape, the article supports the outlook of effective project management in civil engineering.

In general, the start of a large-scale construction and industrial project requires the preparation and supply of several prerequisites at the management and plant in the higher levels. At the plant levels, these prerequisites are anticipated in the form of a work package called site mobilization, from the time of price proposal and contract conclusion, and it enters the implementation phase after the kick of meeting. This work package supports the project until the end of the provisional acceptance and sometimes the final acceptance (guarantee period) which is defined based on the needs, structure, nature and goals of each project. In the implementation phase, project management and support has been done through the system which has been defined in the site mobilization. It is obvious that any mistakes, lack of predictions, non-compliance with the requirements and needs of the project will cause a delay in the schedule, the cost of changes will increase and human resources will be under the pressure and etc.This research is based on the experience gained from implemented projects and previous studies to state the standardized method for the site mobilization phase of EPC contracts and industrial projects.

Conventional concretes, which are designed, mixed, transported and processed by traditional methods, cannot be used to achieve the desired specifications for special applications or to achieve specific requirements. Strength alone cannot answer all the properties related to concrete, especially its durability, and it is necessary to consider its reliability and durability in addition to the issue of resistance and bearing loads during the service life of concrete for different areas. In recent years, on the reinforcement used in reinforced concrete structures, developments in concrete have been placed at the top of the research programs of some countries of the world. The opinion of most experts and practitioners of concrete works has been drawn to this issue that strength alone cannot answer all the properties of concrete, especially its durability, and it is necessary to design concrete for different areas in addition to the issue of resistance and bearing loads during the service life. Its reliability and durability should also be considered. In recent years, there has been a huge change in concrete technology and the emergence of new concretes.

Construction companies today are facing a new environment. Iranian construction and construction companies suffer from low productivity and many managers have struggled to find appropriate solutions to this problem. It seems that using project management information systems to improve managers' management and increase their productivity could be one of these solutions. But because of the special features that govern these construction and development companies, especially the problems of the human resources (including managers and employees), it is not possible to apply this tool in practice and to observe it in practice. It has become less of a company that has been able to use these project management information systems efficiently. Therefore, if research can identify the key components in implementing a project management information system in bulk construction projects and provide solutions for the effective use of these project management information systems, it will certainly be a useful step in solving corporate problems Construction removed. The present study aims to investigate the impact of implementing project management information systems on the success of project development projects, which include improving the quality, cost and time components of the project depending on the content dimensions of the quality of the project management information systems, which also include the accuracy components.

In today's world, urbanization in all its dimensions is expanding rapidly, and city managers are trying to meet the expectations of citizens and organizations, from the city and urban management, and to manage the city in a changing environment. Today, plan and operate. Administration of cities in the past, due to their small size and population, was possible through government assistance such as tolls. Meanwhile, government budgets are normally limited and inefficient to develop the infrastructure needed by a country. This research identified and prioritized the challenge of such contracts using qualitative and quantitative methods, which can be referred to the challenges of construction and operation, the private sector and the challenges of the public sector. The results of this study include the public sector challenge with a weight of 0.421, the private sector challenge with a weight of 0.391 and the manufacturing and exploitation sector challenge with a weight of 0.188, which were placed in the first to third priorities, respectively. In addition, four key and effective factors in the successful implementation of public-private partnership schemes can be mentioned as follows: Ensuring free access to the market and the possibility of fair and non-discriminatory competition in the economic context of society, protection of the interests of society And maximizing the added value of public-private partnership schemes, defining the optimal level of government assistance both to identify necessary and sustainable projects and to prevent the misuse of government property for windfall profits and to evaluate the most effective type of partnership with regard to The type of project desired.

To eliminate the defects of merely systematic materialistic attitudes, one can refer to the divine systematic thinking and benefit from the transcendental teachings of Islam. Non-linear thinking and dynamic view of phenomena and consequences is the neglected point of managers' decisions in businesses and commercial and non-commercial organizations. The employees of the organization always seek to know the results of their performance and are interested in monitoring their performance changes. In all the organizations of the world, managers and organizational leaders seek to improve and improve the performance of their organizations. Organizational performance is an indicator that measures how an organization or institution achieves its goals. With the aim of investigating and evaluating organizational performance through systemic thinking, this article reviews the viewpoints of managerial and organizational performance evaluation criteria, indicators and types of performance evaluation models. The results showed that the design and selection of performance evaluation indicators is one of the basic phases in the design of the organizational performance management system. In the performance evaluation process, the organization excellence model (EFQM) is a self-evaluation process and a comprehensive systematic method to identify the organization's strengths and improvement points. As a result, the organization compares itself with the best in the world or national class.

One of the effective methods in improving the seismic behavior of structures is the use of light steel structures (LSF) systems. The (LSF) system, which is made of cold-rolled steel sections (CFS), has been widely used in the industrial production of commercial and residential buildings for about 20 years, and as a suitable alternative to traditional construction methods. It has found a special place in the construction industry of advanced countries. These types of systems receive a small amount of lateral force during severe earthquakes, and due to two special properties, i.e. prefabricated structural members and suitable thermal insulation, these systems are widely used in The advanced countries of the world are used to build residential houses. Wooden buildings show good resistance against earthquakes. In a wooden structure, low to moderate vulnerability to earthquakes is usually observed. One of the reasons for the good performance of these buildings against earthquakes is their light weight compared to other types. Also, the presence of many non-structural components such as load-bearing walls increases the amount of energy wasted by the building against earthquakes. In addition, the presence of many joints increases the malleability of the building.

The issue of increasing efficiency and improving the executive performance of construction has been one of the goals and concerns of regulatory bodies such as the municipality and the Engineering System Organization. At First, what is taken from the executive supervision concept is that the presence of the building's supervisor is the main responsibility for ensuring the building's quality. But in reality, there are countless factors behind of a building construction process that cause a decrease in the quality of executive supervision and ultimately a decrease in the executive quality of a construction. The main purpose of this article is to review the defined role of the supervising engineer by the Engineering System Organization in the field of construction, to examine various factors in the decline in the quality of executive supervision by statistical data obtained from the community and finally suggestions to increase the efficiency of executive supervision.

As the population grows, the construction industry, like other industries, is growing rapidly, and much of this growth can be seen in metropolitan areas. The increasing need for construction has led to the tendency of constructions to the cheapest and poorest type, in parallel with high profitability. After a while, with the initial wave of excessive demand for the building descending, when the demand showed a more reasonable trend than in the past, a number of well-known builders acted with the correct knowledge of the opportunity in the market according to the needs of affluent customers in a competitive environment. By using special architectural effects and creating a special style, through branding construction and branding, they showed a commitment to providing a guarantee of building quality. Since such buildings are built by famous architects and builders, so the building and their builders have a special brand. Therefore, buyers of luxury residential complexes, which are often highly priced, decide to buy when considering several factors. As a result, the present study aims to identify and rank the factors affecting the intention to purchase a luxury brand building. The present research is applied in terms of purpose and descriptive in terms of data collection method. The statistical population of the present study is the Committee of Experts. According to the purpose of the research, it consists of 8 builders familiar with the subject of luxury buildings with at least ten years of experience in the construction of luxury buildings. The method of selecting experts has been purposeful. In this research, the DANP approach has been used. In the first step, the Dematel technique and in the second step, the network analysis technique (Anp) are used to rank the criteria. According to the values of the final weights obtained for each criterion, it is observed that the individual criterion with a final weight of 0.334 is the first priority, the construction criterion with a final weight of 0.333, the second priority, the environmental criterion with a final weight of 0.332 is the third priority. they give. Among the sub-criteria are personal satisfaction with a final weight of 0.094, building facilities with a final weight of 0.088, perceived quality with a final weight of 0.086, three sub-criteria that have the highest rank in the intention to buy a luxury building in Shiraz have given.
