Purpose: This study aims to examine the impact of transformational leadership on green innovation and green learning in construction supply chains.Design/methodology/approach: A theoretical framework of research hypotheses between transformational leadership, green learning and green innovation is developed. Using a survey questionnaire, data are collected from construction firms in Vietnam. Structural equation modeling is used to test the research hypotheses.Findings: The results indicate that transformational leadership promotes both green learning and green innovation (i.e. green product innovation and green process innovation) while green learning positively affects green process innovation. Furthermore, it is found that green learning mediates the linkage between transformational leadership and green process innovation.Research limitations/implications: This study contributes to the development of leadership research in construction by showing the significance of leadership at the supply chain level.Originality/value: Leadership is regarded as a key factor for most organizations' success and competitive advantages. In construction, leadership has been widely studied at the project and organizational levels while its important role is also explored at the supply chain level. Nevertheless, in terms of construction supply chains, there has been still very limited evidence about the effects of transformational leadership. Thus, this study fills the gap in knowledge by empirically examining the relationships between transformational leadership, green learning and green innovation.

Many governments in the world are now under heavy pressure for improving services of health care whilst always attempt to use their scarce resources efficiently. Hospital buildings are basically one of the important elements of health care systems. This paper aims to determine factors causing cost overrun in Vietnamese hospital projects. Survey questionnaire and Exploratory Factor Analysis (EFA) are two main methods. The finding indicates that main groups causing cost overrun in hospital projects are: additional work, material cost, and delays. Based on groups of cost overrun, twenty factors were also discovered as well as ranked. In addition, solutions were suggested to solve the cost overrun issue, and then comparisons with previous studies were presented. Results of the study could be applied to monitor policies for the management of hospital projects, and support practitioners in attaining the success of hospital projects.

Purpose: The research objective is rooted in the principle of providing new insights and a collective perspective regarded as Supply Chain Quality Management 4.0 (SCQM4.0), an integration of all three concepts – Industrie 4.0, quality management and supply chain management.Design/methodology/approach: A thorough review of historical developments and existing integration trends among Industrie 4.0, quality and supply chain approaches along with future research directions outlined in the main literature, was conducted. This work establishes a knowledge base on research topics, issues of integration and synergies with a concentration on the potential for deeper integration with supply chain operations.Findings: This article not only introduced the term SCQM4.0 and proposed a definition for it, but also contributed a novel conceptual SCQM4.0 framework and evolutionary perspective through the SCQM4.0 maturation model. Stemming from the gaps, opportunities and benefits identified in the literature, the conceptual SCQM4.0 framework builds on the high potential of the SCQM4.0 constructs to achieve successful governance and implementation. Under the SCQM4.0 maturity framework, it provides a clear evolutionary path underpinned by the SCQM4.0 constructs.Research limitations/implications: In the effort toward a successful SCQM4.0 implementation, the proposed SCQM4.0 maturity frameworks will be a “road map” for businesses to develop fully and actively in supply chain operations, bringing quality products and services for the company. Industry practitioners are encouraged to perform gap analysis and direct the implementation of the strategy to establish an excellent SCQM4.0.Originality/value: This is one of the pioneering studies integrating all three concepts (Industrie 4.0, quality management and supply chain management), connecting the link and discovering more synergies to support the future development of more holistic management models. SCQM4.0 is expected to expand on the strengths, synergies and established relationships between technologies 4.0, quality and supply chain, contributing toward a pioneering and quality supply chain.

Infrastructure projects are very essential in societies today because they enable the uninterrupted flow of goods, services, and information across any country. Although much research has been done to investigate cost overrun in different infrastructure projects such as transport, bridge, power plant, road, or even petroleum; little is known about what factors cause the most significant cost overrun in transmission lines construction projects. In order to fill this literature gap, the current study is aimed at identifying main cost overrun factors in these projects. A literature review is first conducted to capture causes of cost overrun in the construction industry. A survey questionnaire is then designed to collect data from transmission lines projects in Vietnam. Factor analysis is applied and seven factors of construction cost overrun are extracted including: risks, resources, incompetence of parties, firm policies, project policies, poor collaboration of parties, and components, transportation and machinery cost. A regression model is subsequently developed to assess the impact level of these seven factors on cost overrun. It is concluded that risks, resources, incompetence of parties, and components, transportation and machinery cost are the four main causes of cost overrun in transmission lines projects while the remaining factors are found to have no impact. The paper ends by pointing out limitations of the study and providing some suggestions for future research.
