This study investigates critical research gaps in procurement management challenges faced by Chinese contractors in international engineering–procurement–construction (EPC) projects under the Belt and Road Initiative (BRI), with a particular focus on sustainability-oriented outcomes. It examines the following: (1) prevalent procurement inefficiencies, such as communication delays and material shortages, encountered in international EPC projects; (2) the role of supply chain INTEGRATION in enhancing procurement performance; (3) the application of social network analysis (SNA) to reveal inter-organizational relationships in procurement systems; and (4) the influence of stakeholder collaboration on achieving efficient and sustainable procurement processes. The findings demonstrate that effective supply chain integration significantly improves procurement efficiency, reduces delays, and lowers costs, thereby contributing to more sustainable project delivery. Strong collaboration and transparent communication among key stakeholders—including contractors, suppliers, subcontractors, and designers—are shown to be essential for mitigating procurement risks and supporting resilient supply chain operations. SNA results highlight the critical roles of central stakeholders and their relational structures in optimizing resource allocation and enhancing risk management capabilities. Evidence from case studies further indicates that Chinese contractors increasingly adopt sustainability-oriented practices, such as just-in-time inventory management, strategic supplier relationship management, and digital procurement platforms, to reduce inefficiencies and environmental impacts. Overall, this study underscores that supply chain INTEGRATION, combined with robust stakeholder collaboration, is a key enabler of sustainable procurement and long-term competitiveness for Chinese contractors in the global EPC market. The purpose of this study is to identify critical procurement management challenges and propose evidence-based solutions for Chinese contractors. It further aims to develop a sustainability-oriented framework integrating supply chain integration and stakeholder collaboration to enhance competitiveness. Full article

This study creates and refines a risk–effectiveness–integrated dynamic simulation framework that brings together risk and effectiveness factors affecting qualified workforce allocation in multi-project contexts, specifically in the construction of industrial production facilities. Based on a case study of three overlapping projects in West Java, Indonesia, this study examines the requirements for an expert workforce across the Engineering, Procurement, and Construction (EPC) phases. Conventional mitigation measures generally assume that a qualified expert workforce is immediately available. However, hiring the right personnel with specific qualifications for a project takes time. To fill this gap, this paper presents a system dynamics-based model that explicitly integrates quantified project risks and execution effectiveness to determine expert workforce requirements at the multi-project level. This aspect is often addressed implicitly in the existing workforce planning approaches. This mixed-methods strategy includes a literature review, variable validation, simulation modeling, and case analysis. The results show that workforce planning based on integrated risk and effectiveness factors significantly improves project delivery by anticipating expert workforce shortages and reducing the need for reactive solutions. Model validation using real project data demonstrates that the simulated expert workforce demand reproduces both the average behavior and variability observed in real-world practice, satisfying quantitative behavioral validation criteria across projects and the EPC phases. The model contributes to sustainability by enhancing long-term workforce resilience, reducing resource waste, and supporting more efficient industrial project delivery. Full article

China’s prefabricated construction industry, despite its recent emergence, faces challenges such as limited standardization, poor integration, and low industrialization. In the Engineering, Procurement, and Construction (EPC) model for prefabricated buildings, numerous risks arise due to the long project lifecycle, complex technical requirements, and force majeure factors. These risks may cause substantial project losses if not effectively controlled. This study, from the perspective of general contractors, explores risk assessment for prefabricated building projects under the EPC model to promote construction practices and enhance project resilience. The objective is to help contractors mitigate risks and ensure the smooth and environmentally responsible implementation of prefabricated projects. Risks were identified through literature review and case analysis, and a statistical process refined them into a structured index. The Analytic Network Process (ANP) was applied to assign indicator weights, establishing a comprehensive risk evaluation model. The Gray System Theory was then employed to assess the risks in a case study from Southwest China, validating the effectiveness and applicability of the proposed model. This research provides a systematic approach and theoretical support for EPC-based risk assessment, offering guidance for risk management and contributing to development in the construction industry.

As one of the most technically and managerially complex types of construction projects, super-high-rise buildings require deep multidisciplinary integration and intensive collaboration throughout their lifecycle. Conventional stage-based delivery models, such as the EPC, are often inadequate for handling this complexity. In recent years, the integrated Financing–Engineering, Procurement and Construction–Operation (F+EPC+O) model has emerged to address lifecycle governance challenges in building projects. This study explores how an investment-led F+EPC+O model builds dynamic capabilities to enable lifecycle collaboration in complex projects. It is based on a case study of the Xiamen Hemei Center and employs a qualitative case study approach to examine the operation of an internal F+EPC+O in the project. Drawing on multi-source data, including internal archives, BIM/CIM logs, and interviews, the findings identify three elements—lifecycle incentive alignment, internal power symmetry, and extended operation duration—that shape the Sensing–Seizing–Reconfiguring (SSR) capabilities of the approach. Specifically, Sensing is achieved through NPV-based decision frameworks and cross-stage trade-off lists; Seizing is achieved through BIM/CIM issue closure and joint rapid-cycle decision-making; and Reconfiguring is achieved through performance feedback and institutionalized knowledge repositories. The findings indicate that the SSR dynamic cycle transforms institutional integration into value co-creation, turning project complexity into a source of collaborative advantage. Full article

Against the backdrop of policy-driven transformation in construction industrialization, the EPC general contracting model has emerged as a core pathway for the large-scale development of prefabricated buildings. However, the EPC mode integrates the links of design, procurement, production, and transportation, construction, resulting in a complex coupling correlation among the risk factors of prefabricated construction schedule, which is easy to induce the risk contagion effect and increase the difficulty of risk control of project schedule delay. To address this, this study constructs a hybrid model integrating the “Fuzzy Interpretive Structural Model (FISM)-Coupling Degree Model-Bayesian Network (BN)” to systematically analyze risk contagion mechanisms. Taking an EPC prefabricated building project as an example, FISM is used to reveal the hierarchical structure of risk factors, while the coupling degree model quantifies interaction strengths and maps them into the BN to optimize conditional probability parameters. Through comprehensive hazard analysis, seven key causal risk factors and two critical risk propagation paths are identified. Targeted control measures are designed for the key risk factors, and BN-based simulation is applied to locate critical risk nodes and implement break-chain interventions for the risk paths, resulting in a 23% reduction in the probability of schedule delay. Engineering applications demonstrate that this model can effectively achieve the dynamic identification and blocking of risk paths, providing valuable reference for similar projects and offering informed support for managers in formulating scientific response strategies.

Government-invested Engineering, Procurement, and Construction (EPC) projects often encounter challenges, such as ambiguous value-added pathways and undefined key driving mechanisms, which impede efficiency improvements during implementation. To systematically elucidate the value-added pathways and core driving mechanisms in these projects, this study identified and distilled 20 critical influencing factors across four dimensions—contract cost, organization, technology, and environment—through a combination of a literature review, case analysis, and a questionnaire survey yielding 68 valid responses. Employing a DEMATEL–TAISM–MICMAC hybrid model, the research conducted an in-depth analysis: the DEMATEL method quantified the interdependencies among factors and identified key causal elements; a TAISM-directed topological hierarchy diagram was constructed to clearly delineate the hierarchical transmission pathways; and the MICMAC model was utilized for driver–dependency analysis, classifying factor roles and providing cross-validation from three analytical perspectives. The results indicate that S₁₂ (collaborative participation in early planning and design phases) exhibits the highest causal influence and serves as the core driving factor, while S₁ (detailed and explicit contractual clauses) and S₁₂ are positioned at the root level of the hierarchical model, functioning as foundational independent factors that regulate the entire system. The value-added pathways are characterized by a hierarchical transmission logic of “root level → transitional level → direct level”. Based on these findings, the study proposes a system optimization strategy of “strengthening the root level, optimizing the transitional level, and safeguarding the direct level”, thereby offering both theoretical insights and practical guidance for enhancing the value-added efficiency of government-invested EPC projects.

This study assesses the performance impact of lean construction practices in Engineering, Procurement, and Construction (EPC) projects in China. While lean methods have demonstrated substantial benefits in conventional construction, their implementation in the EPC context—characterized by higher complexity and integration—remains underexplored, particularly within the Chinese infrastructure sector. This research develops a structured framework that classifies lean practices into five functional categories: planning and scheduling (PS), process and workflow optimization (PWO), quality and safety enhancement (QSE), resource and maintenance (RM), and visualization and communication (VC). This study evaluates the influence of these practices on four key performance indicators: efficiency and resource management, quality and safety, stakeholder satisfaction, and organizational and market impact. Data were collected from 456 EPC stakeholders via a structured questionnaire and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings reveal that PS, PWO, and QSE exert the strongest positive effects on performance, while RM and VC contribute in more context-specific ways. The results highlight the value of lean practices for improving operational performance, stakeholder engagement, and sustainability in complex project delivery systems and underscore the need for policy support and digital integration to enhance lean adoption in Chinese EPC sector.

The Engineering, Procurement, and Construction (EPC) model—particularly the design-led consortium structure—has proven effective in enhancing design quality, improving construction feasibility, and reducing project costs. Nonetheless, its broader application remains constrained by difficulties in quantifying consortium members’ future benefits and establishing an equitable benefit distribution mechanism. These issues often undermine cooperation and limit the scalability of the model. To address these challenges, this study proposes a benefit distribution model that incorporates two quantifiable indicators of members’ future benefits: the bid-winning rate and the profit margin of future projects. The model further enhances fairness by modifying the classical Shapley value method. It introduces a cost compensation factor and a benefit entitlement influence factor to account for differences in both resource input and initial contractual entitlements. Results from a case study of a national highway reconstruction project in Hangzhou, China, demonstrate that the proposed model produces distribution outcomes more closely aligned with actual contractual benchmarks and improves fairness and acceptance among consortium members.

The accumulation and delayed processing of notices generated during the engineering construction process have a significant impact on project settlement and, thus, project cost. Currently, there is a lack of research on intelligent notice processing. Although large language models (LLMs), such as ChatGPT, have demonstrated exceptional performance in natural language processing, their effectiveness in specific vertical fields, such as construction engineering, is limited due to a lack of specialized training. In light of this, this study proposes a knowledge-augmented language model for intelligently processing design notices in EPC (engineering–procurement–construction) projects. This method consists of the following three key components: database construction, price retrieval, and prompt development. During database construction, exception detection was introduced to ensure data quality, and an appropriate database framework was proposed. The price retrieval module features innovative retrieval rules for improved efficiency and accuracy. Prompt development was based on mainstream methods, which were tailored for this task. The result of processing notices includes cost analysis and claimability judgement. The method achieved promising results in experiments with real project data. Based on these results, the paper discusses the model’s advantages, application scenarios, and input text requirements, providing insights and suggestions for future research. Full article

Integrated supply chain management is essential for enhancing procurement efficiency and project outcomes in international engineering, procurement, and construction (EPC) projects. Despite its acknowledged importance, there is a paucity of understanding regarding the precise effects of supply chain integration on procurement processes in this context.

Essential elements, including operational performance, procurement contract management, and stakeholder engagement, are identified as critical determinants of project success. The study seeks to examine how international EPC contractors incorporate the complete procurement management process via supply chain integration. Contractors can improve operational efficiency and procurement management by forming partnerships with stakeholders to acquire and integrate resources, hence enhancing project outcomes. This ongoing enhancement process improves procurement efficiency and bolsters the competitiveness of Chinese contractors in the global EPC market. The study underscores the efficiency and sustainability of procurement processes, demonstrating how optimized supply chain integration advances broader sustainability objectives by minimizing waste, enhancing resource utilization, and promoting environmentally and socially responsible procurement practices in international projects. The research offers significant empirical data and insights for academic inquiries and actual company implementations. Full article

China’s “Going Out” strategy and the “Belt and Road” initiative have significantly propelled the expansion of overseas contractual engagements, with a pronounced impact in the Engineering, Procurement, and Construction (EPC) sector. EPC contracting is increasingly recognized for its superior resource allocation and integration efficiency. Within the EPC framework, procurement is pivotal, exerting a direct influence on project cost, schedule, and quality parameters. The biblio-metric analysis of this paper reveals the research trend of EPC projects in the past decade, especially in supply chain integration, procurement management, and stakeholder management. This indicates an increasing interest in efficient project management and supply chain optimization in international engineering EPC projects. Although the application of supply chain integration in the manufacturing industry has been a successful experience, its practical application in construction and EPC projects is still insufficient. Integration strategies mentioned in the literature, such as achieving supply chain transparency through digital platforms, reducing operating costs, and optimizing delivery time, are directions that need to be further explored in this field. Effective supply chain integration and increased maturity of procurement management in EPC projects are still less involved areas. In addition, there is also a lack of research on how to manage high-risk and unpredictable risks in large international engineering projects. This article suggests that future research should focus on developing flexible supply chain management tools and practices to adapt to a project-oriented supply chain environment. Full article

As global economic integration and rapid technological advancements transform international business, international engineering contracting has become essential for achieving sustainable development goals (SDGs). This paper investigates the significant impact of China’s strategic initiatives, notably the “Going Global” strategy and the Belt and Road Initiative (BRI), on the operational practices of Chinese enterprises involved in overseas investments. Central to this transformation is the Engineering, Procurement, and Construction (EPC) model, which emphasizes the integration of supply chain management and stakeholder collaboration to enhance performance in international EPC projects and underscores the crucial role of these elements in promoting sustainability. Incorporating insights from social network data analysis, this study reveals that contractors collaborating with various stakeholders—such as owners/consulting engineers, domestic and foreign customs departments, and group headquarters/design parties—exhibit a high degree of similarity in personnel profiles. This suggests that the internal organizational structure and personnel allocation of contractors could be optimized to enhance operational efficiency, aligning with the collaborative patterns identified. This study addresses a critical research gap by exploring how effective supply chain management and collaborative stakeholder engagement within multinational EPC projects contribute to sustainable outcomes. Employing advanced social network analysis software, the research examines the complex interactions among stakeholders and their influence on procurement dynamics. Findings indicate that strong relational networks and strategic collaborations significantly enhance procurement efficiency and project success, underscoring the importance of supply chain integration. Ultimately, integrating supply chain management principles into the EPC model not only offers innovative perspectives for advancing sustainability in international projects but also provides actionable insights for improving project outcomes within the BRI framework. This research underscores the pivotal role of supply chain organization and stakeholder cooperation in achieving sustainability objectives, thereby enriching the discourse on sustainable enterprise operation and supply chain management in the context of global initiatives.

The 14th Five-Year Plan for China proposes to promote the urbanization process from a county perspective, presenting an unprecedented opportunity to develop county urbanization. However, in the context of relatively limited resources, insufficient funds, and comparatively lower land values in Chinese counties, how to promote county urbanization remains the primary challenge, which has not been studied yet. This study first analyzes the necessity of promoting county urbanization from four dimensions: national development strategy, industrial policy development, local government status, and enterprise development demands using literature research and survey interviews. Based on field research conducted in 32 counties in China, the strengths, weaknesses, opportunities, and threats (SWOT) analysis is carried out on the county urbanization process in this study. By analyzing the developmental status and challenges of major urban areas, expansion areas of counties, and their surrounding countryside, this paper proposes a “three-level gradient integration” concept for the spatial integration of county urbanization. Furthermore, the mechanism of multi-agent linkage to promote county urbanization was explored based on the theory of urban governance and the characteristics of county urbanization. Subsequently, relying on the analysis of policies, such as land acquisition and integrated land improvement, and adopting modes, such as “Investor + Engineering Procurement Construction + Operation” (investor + EPC + O) and renovate–operate–transfer (ROT), we propose a pathway for promoting county urbanization through the linkage of government, enterprises, and residents. This study provides insight into promoting the county urbanization process. Additionally, each country faces the common issue of how to use limited resources to promote regional development, and this article can provide valuable insights and inspiration for addressing this shared issue by the principle of adapting to local conditions and adhering to the concept of efficient market and proactive government.
