Reducing target reliability index of concrete bridge beams through compression yielding

Damage to reinforced concrete (RC) bridges due to accidental overloading is inevitable, especially for those that deteriorate over time due to various environmental and operational factors. When significant damage occurs, it needs to be replaced. However, replacing bridges is expensive and time-consuming. This problem can be well resolved by the concept of compression yield (CY) structures. When an overload occurs, the CY block in the beam is triggered like a fuse, forcing the beam to deform in a ductile manner, thus preventing further overloads. Additionally, the damaged CY blocks can be replaced without replacing the entire beam. Due to this safer failure mode and lower cost of failure, the safety reserve of the CY beam can be significantly lower than that of the traditional RC structure, which means that the target reliability of the CY bridge needs to be re-established. The objective of this study is to develop the target reliability of CY bridge. The target reliability of structures is determined through cost optimization. The life-cycle costs for bridges are determined based on the practical construction and post-construction management process. The calculated results indicate that although the initial cost of CY beams could be higher, the losses associated with failures are significantly lower compared to RC beams. Consequently, the target reliability and life cycle costs of CY bridge can be lower than those of the RC bridge.

An Overview of Circular Economy Management Approach for Sustainable Construction and Demolish Waste Management

<p>The construction industry has been identified as a major contributor to environmental degradation, particularly through the generation of waste. Unsustainable production and consumption patterns in the construction industry have resulted in high amounts of waste, which is often disposed of in landfills. To address this challenge, a circular economy management approach has been proposed to achieve sustainable construction and demolition waste management. This review provides an overview of the circular economy management approach for sustainable management of construction and demolition waste. The circular economy management approach emphasizes the need to reduce waste generation and promote the reuse and recycling of materials. This approach also advocates the use of sustainable materials and the implementation of effective waste management practices throughout construction and demolition. The circular economy management approach to sustainable management of construction and demolition waste includes several key strategies, including adopting sustainable design and construction approaches, promoting reuse and recycling of materials as well as developing effective waste management systems. These strategies require the cooperation and involvement of all stakeholders in the construction and demolition process, including architects, contractors, developers, and waste management companies. The circular economy management approach offers a promising framework for achieving the goals of destructive waste management and sustainable construction. By promoting sustainable patterns of production and consumption, this approach can help reduce the environmental impact of the construction industry while generating economic benefits for stakeholders. However, successful implementation of this approach requires strong regulatory support and the willingness of all stakeholders to adopt sustainable practices.</p>

Оценка эффективности системы управления крупномасштабными строительными проектами в течение их жизненного цикла

The relevance of the study is due to the increasing importance of large-scale construction management processes throughout the full life cycle, as well as the system-technical nature of the problems that arise in this case. To determine the effectiveness of the management system, the principles of a systematic approach can be applied, in which the subject of economic activity is considered as a single whole with an ordered structure and relationships. It has been established that currently there are many problem-oriented models (simulation, optimization, expert) containing various quantitative indicators and methods for determining effectiveness aimed at finding economically feasible management solutions and providing for their subsequent practical implementation. However, a unified methodological understanding on the issues of evaluating the effectiveness of large-scale construction management has not yet been achieved. The purpose of the study is a methodological justification of a holistic approach to evaluating the effectiveness of a large-scale construction management system. As a working hypothesis, the assumption of a direct inextricable link between the integrity of the management system and the effectiveness of its functioning is accepted. The conceptual framework of the theory of integrity, mathematical statistics, and set theory is used within the framework of a systematic approach. As a result of the conducted research, an understanding of the effectiveness of large-scale construction management has been developed as the integrity of the solutions embedded in it, expressed by a set of any assessments that adequately express the need and possibility of implementing these solutions. The economic aspect of the systemic efficiency of capital management of a construction enterprise is investigated and a variant of its cost (monetary) assessment is proposed. The result obtained in the course of the study can be used as the basis for the development of a wide class of tasks for multi-criteria optimization of the operation of any large-scale construction management system throughout the full life cycle.

IMPACT OF CONSTRUCTION ACTIVITIES ON RESIDENTS OF CAPE COAST NORTH METROPOLIS, GHANA

Construction projects have caused significant disruption in urban areas. Despite the need to limit the environmental impacts of construction operations, stakeholders often fall short, resulting in negative consequences for nearby residents. Aim: This study aimed to investigate the effects of various construction activities on residents of the UCC and CCTU campuses in the Cape Coast North Metropolis, Ghana. Methodology and Results: Using a stratified and random sample of 100 residential houses from the University of Cape Coast and Cape Coast Technical University, questionnaires were administered to residents in university-owned dormitories, private hostels, and faculty/staff housing. Data were analysed using Excel and IBM SPSS, focusing on modelling the relationship between variables and assessing their influence. The results indicated that construction operations impacted the environment and residents of the Cape Coast North Metropolis. The R and R Square values indicated that construction activities affected residents' responses. Meanwhile, the adjusted R Square accounted for the complexity of the model, with a standard error measuring the average prediction error. The constant term was considered significant, representing the expected value when all predictors were zero. Conclusion, significance, and impact: From initial ground disturbance to eventual decommissioning, construction projects can lead to soil degradation, habitat destruction, and increased carbon emissions. There is a need to prioritise sustainable and resident-friendly construction practices by incorporating responsible construction methods that mitigate the negative impacts on both residents and the environment. Continuous evaluation will enable better management and improvement of construction processes, leading to stakeholder benefits. Policymakers should explore eco-friendly building techniques, considering construction impacts.

Analysis of the Mechanism for Selecting Organizational and Technological Solutions for Integrated Management of Construction Processes

Purpose. The main purpose of this article is to thoroughly substantiate the possibilities of implementing a mechanism for selecting organizational and technological solutions to achieve parametric criteria for managing construction processes, especially under conditions of uncertainty. To achieve this goal, we use a functional model of the system-integrated approach, which allows us to systematize and coordinate management functions at the level of individual processes. Methodology. The study is based on the introduction of new requirements for standardization in the construction industry, in particular, on the use of the parametric method. This method can improve management strategies, methods, and technologies, as well as facilitate the implementation of innovative organizational and technological solutions. As a result, the quality and volume of construction can be improved, which, in turn, will help overcome the crisis and develop the construction industry. The management process involves achieving a key goal, namely the efficiency of project implementation, while construction has certain specifics that complicate the management process and require the use of more complex, integrated, and multi-directional organizational and technological solutions. Findings. In the current economic environment, which provides for both an increase in the number of risks in the construction sector and the size of their possible consequences, in the context of increasing (expanding the list) of quality requirements for construction projects, there is a reasonable need to search for and improve organizational and technological solutions in order to apply new approaches to the management of construction processes related to the practical implementation of the results of modern scientific and methodological research. The results obtained, however, indicate that the use of the parametric method creates new challenges for the efficiency of management in the construction industry. The increased number of management decision alternatives, identification of risks and improvement of consequence forecasting processes may cause certain difficulties. On the other hand, the lack of clear requirements can lead to increased costs and risks. Originality. The paper substantiates the necessity of using a system-wide algorithmic mechanism for the effective management of construction processes under conditions of uncertainty. This is important for adapting to modern challenges and ensuring the sustainable development of the construction industry. Practical value. The study makes it possible to determine the compliance of organizational and technological solutions with the established criteria and compare them to select the most effective one, in particular in terms of cost, efficiency and risk mitigation.

Exploring the Acceptance of the Technical Disclosure Method Based on 3D Digital Technological Process by Construction Workers through the Perspective of TAM

Effective pre-control methods for construction workers during the construction phase are important means to ensure the final quality of the construction product. The 3D digital technological process introduces model-based definition (MBD) to the construction industry and enhances construction process management to some extent by combining it with building information modeling (BIM). However, the proper application of the 3D digital technological process requires a good knowledge of the factors associated with its acceptance. This study introduced the 3D digital technological process into technical disclosure and further explored the factors that may influence its acceptance among the construction worker population. Several new extrinsic variables, cognitive level, subjective norms, technology anxiety, and enjoyment, were added and evaluated in the technology acceptance model (TAM), and a total of 314 data samples were collected to verify the hypothesized paths. The results showed that the proposed model was effective in predicting the attitude of the worker population towards this method.

A research on data integration and application technology of urban comprehensive pipe gallery based on three‐dimensional geographic information system platform

AbstractThree‐dimensional Geographic Information System (3D GIS) technology is often used in geology, mining, hydrology and other fields. It is also used in intelligent management of urban comprehensive pipe gallery projects, because the real environment with the sky, ground, and underground can be intuitively simulated in the virtual reality environment by 3D GIS platform. Through the research on data integration and application technology of urban comprehensive pipe gallery, the 3D model of comprehensive pipe gallery project data can be created based on Building Information Modelling and GIS technologies, and a comprehensive underground pipelines network management information system has been developed to realise the integration of various data, including 3D data of comprehensive pipe gallery model and underground pipe network model, 2D or 3D GIS data of the ground and underground etc. On this basis, the functions of intelligent planning and approval management, the safety analysis and disaster prevention planning and decision‐making of urban comprehensive pipe gallery projects can be further realised. The research results have been applied to the planning and construction process management of the comprehensive pipe gallery project in the sub‐centre of Beijing.

QUALITY MANAGEMENT PLATFORM INSPIRED DURING COVID-19 PANDEMIC FOR USE BY SUBCONTRACTORS IN PRIVATE HOUSING PROJECTS

Due to the COVID-19 pandemic in Taiwan, many construction sites must limit the number of people on the jobsite or conduct work independently to avoid the spread of COVID-19. The quality of construction may be in doubt with unclear job handover, especially when workers have COVID-19 infection that should be isolated immediately. On top of that, first-level subcontractor self-inspections are crucial parts of construction process management, and neglecting inspection processes can lead to construction errors and poor quality. To improve current quality inspection methods for private projects, a literature analysis was conducted to identify construction quality management issues that are faced in private housing projects. In-depth interviews with small and medium-sized subcontractors of private housing projects were performed to understand the quality management methods that they use in practice. Next, improvement measures for quality management were formulated and a simplified checklist for private project subcontractors, based on the practical feedback obtained, was created. Finally, the AppSheet platform was used to develop an inspection application for construction, and a subcontractor was invited to confirm its feasibility. The paperless design avoids redundant human contact, and the results of this study greatly facilitate construction practice, particularly during the pandemic. The main contribution of this study is its investigation of the procedures that are used by private project subcontractors to inspect their work for quality management; its results can serve as a reference for academics in evaluating construction quality management levels and improving the management of work by subcontractors to promote safety and health.

An effective MBSE approach for constructing industrial robot digital twin system

Recently, the rapid development of digital twin (DT) technology has been regarded significant in Cyber-physical systems (CPS) promotion. Scholars are focusing on the theoretical architecture and implementing applications, in order to establish a high-fidelity, dynamic, and full-lifecycle DT model and achieve a deep fusion of real and virtual. As a typical complex system with multi-disciplines, multi-physics, and multi-domain characteristics, industrial robot (IR) involves various processes and elements from the two other levels of the system: components and production lines. Their complex relationships lead to a huge challenge to build a comprehensive DT model. Current researchers usually concentrates on single-layer services because of limited construction methodology, which results in enormous isolated models, and leads to low reusable system blocks, finite scalability, and high costs of design, adjustment, upgrade, and maintenance. To address these issues, a standardized methodology and a hierarchical, modular, and generic architecture are proposed to depict comprehensive and variable industrial robot digital twin (IRDT). Firstly, the ontology information model is presented by analyzing variable factors systematically. Then, model-based system engineering (MBSE) based methodology is introduced, including construction process and variants management. After modeling process of three levels (problem domain, solution main, and implementation domain) and four viewpoints (requirement, structure, behavior, and parameter), a generic architecture of IRDT is constructed and a feature-based variants management method is described. Besides, a six-axis IRDTS is implemented to illustrate the mapping of logical architecture and physical system as a multi-level elements and processes representation example. And the steps of numerical evaluations consist of system delay and derivation. Finally, results show the effectiveness and the potential of the proposed theoretical methodology for constructing IRDTS and other industrial applications.

BIM-CAREM: Assessing the BIM capabilities of design, construction and facilities management processes in the construction industry

BIM adoption has accelerated worldwide since it is an important enabling technology for digitalisation in the construction industry. Adopting BIM requires transforming the traditional building life cycle stages (planning, design, construction and facilities management) into BIM-integrated project deliveries. Assessing the BIM capabilities of these stages helps organisations to identify gaps in their BIM uses and improve them. There is a lack of a comprehensive model in the literature for assessing the BIM capabilities of individual building life cycle stages and their processes. Existing assessment models focus on assessing the BIM maturity of construction projects and organisations which do not inform the required BIM improvements for individual stages and their processes. Hence, we iteratively developed the Building Information Modelling (BIM) Capability Assessment REference Model (BIM-CAREM) and demonstrated its usability through multiple explanatory case studies performed with two international design and engineering companies and two general contractors in Turkey. We assessed the BIM capabilities of design, construction and facility management processes of various buildings i.e. residential, stadiums, hospitals and airports. The results showed that the BIM capability levels of design, construction and facility management processes vary within and across the companies.

High risk and impact factors on construction management process − case study of COVID-19 of a hospital in Iraq

The pandemic of COVID-19 crisis suddenly appeared worldwide, and there were no proper crisis management procedures taken in advance to contain such a problem. Moreover, it has had harmful and unmeasured consequences on most life sectors, including construction, which has been severely impacted during the pandemic. This paper aims to review factors with a high-risk impact on hospitals' construction projects during the outbreak of COVID-19 in developing countries by considering the case of Iraq's construction sector. A mixed methodology of qualitative and quantitative research approaches was used. The qualitative method involved (1) a literature review and (2) semi-structured interviews to identify high-risk factors that affect construction projects during the outbreak of COVID-19. The quantitative method involved (1) collecting survey data from 205 industry professionals and experts to determine each risk factor's importance and influence. Cronbach's alpha test to check the reliability of the collected data set, and (3) a fuzzy inference system method was used to assess the impact of each factor on construction projects during the pandemic. The findings of this study indicate that the construction industry has been hit severely during the COVID-19 in Iraq. Moreover, 17 high-risk sub-factors under six main construction factors involve health and safety, risk management, management deficiency, financial, supply chain management and contractual impact hospital construction projects. Furthermore, the most significant risk factors had impacted hospital construction projects by calculating their means were (1) commitment to safety and health recommendations with a level of impact equal to 4.81; (2) risk management procedures with a level of impact equal to 4.63; (3) equipment delivery delays with a level of impact equal to 4.54; (4) worker acceptance of COVID-19 vaccination with a level of impact equal to 4.36; (5) increase of price material with a level of impact equal to 4.18; (6) lack of use of the latest technology with a level of impact equal to 4.09; (7) delay in payments with a level of impact equal to 3.90; and (8) lack of training to deal with the pandemic with a level of impact equal to 3.81. As such, this paper contributes by providing effective policies and measures to mitigate the impact of COVID-19 on hospital construction projects in Iraq.
