Engineering procurement and construction (EPC) is a normative practice globally approved since China has been engaging in international cooperation under the Belt and Road Initiative (BRI) infrastructure development. EPC has been adopted in the delivery of BRI infrastructure projects in other countries. Compared to the domestic method of contract, EPC remains at a low level in management practice, such as a lack of coordinating diverse project stakeholders, high cost of information communication, and risk in complex environments in West Asia (WA). However, no research has conducted a strategic analysis of the current situation of EPC for BRI infrastructure projects in West Asian countries. This study aims to understand the current status quo of EPC for BRI projects in WA by performing a strength, weakness, opportunity, and threats (SWOT) analysis and with the support of data collected from the literature review and semi-structured interviews with EPC stakeholders. The study brings awareness along which internally and externally circumstances of the EPC for BRI infrastructure projects can be perceived by major stakeholders participating. The four critical strategies presented based on the SWOTs identified could help EPC firms develop and promote EPC to implement BRI infrastructure projects in WA at the strategic level.
Purpose The historic Belt and Road Initiative (BRI) is an economic reform policy proposed by the Chinese Government that focuses on connectivity, improved collaboration and more robust economic relations. This paper aims to identify risks involved in BRI infrastructure project and establish a hierarchical relationship among them. Design/methodology/approach The methodology includes two phases, namely, identification of significant risks involved in the BRI project using systematic literature review and to develop a hierarchical relationship between the risks using interpretive structural modeling followed by the MICMAC analysis. Findings This work has identified the 11 risks of BRI infrastructure projects through academic literature. Based on the analysis, economic risk (R3), environmental risk (R1) and political risk (R2) are placed at level six in the ISM model and can significantly influence BRI infrastructure projects. These risks have high driving power, which exaggerates other risks. Research limitations/implications This study would help Engineering Procurements and Construction contractors in strategic decision-making select risk mitigation strategies and make robust and efficient infrastructure projects. However, additional factors may be considered, which are essential for the BRI infrastructure project. Originality/value This research’s novelty lies in the advancement of expertise in project risk assessment. This study contributes by identifying the most significant risks involved in the BRI project. The integrated ISM-MICMAC approach provides a macro picture of BRI project risks to formulate better strategies for its success.
Since the Belt and Road Initiative (BRI) has been put in practice by the Chinese government, several High-Speed Railways (HSR) have been built by Chinese Engineering Procurement and Construction (EPC) firms. However, many delays have created severe detrimental consequences on the progress of most HSR projects. This study sought to explore the essence of the recurring triggers of delays in international EPC HSR projects under the BRI, and a structured questionnaire survey approach was applied to compile the first-hand dataset from Chinese EPC firms working for BRI infrastructure projects. The data were evaluated, and the Relative Importance Index (RII) was adopted to assess the magnitude of the important delay triggers. The findings suggest that HSR projects are still susceptible to unavoidable delays in global construction infrastructure projects. In the engineering phase, improper management of the design, unsustainable land acquisition, and insufficient use of EPC joint venture are the salient trigger of delays. In the procurement phase, the leading causes of unsuitable procurement, undervalued procurement cost, inefficient logistics in labor and materials, improper planning, unqualified site supervisors, inefficient technical standard management, and inefficient constant payment terms are likely to trigger delays in the construction phase HSR projects. Five critical groups of delay factors are identified by this study, which has an essential primary contribution to the body of knowledge and is helpful to EPC contractors working for HSR projects under BRI.
Shear strength (τ), shear stress (σs) and slope angle (β) plays a very important role in the stability of any soil slope. This research investigates the slope stability of a soil slope in order to determine correlations between shear strength with slope angle and shear stress. The assessment and calculation of the soil slope are carried out using slope stability analysis methods that assumed the failure surface as circular slip surface. A limit equilibrium software namely Slide and numerical modelling software namely Statistical Package for Social Sciences (SPSS) are used for the analysis. A total number of two hundred analysis are performed with varying slope angle of 70 to 88 degrees. Correlations are developed between τ, β and σs, which shows a very close relationship of all these three parameters. Applicability of the equations is above 97%. The correlations can be used in any slope stability project to know about the shear strength of the slope with variation in the value of slope angle and shear stress.
