Barriers to public private partnership projects in developing countries

Purpose – Top managers who possess outstanding leadership competence make significant contributions toward achieving project success. The relationship between the top managers’ leadership and infrastructure sustainability (IS), one of the most important project success criteria, is empirically researched in this study. The purpose of this paper is to explore relationships between top managers’ leadership competence of intellectual competence (IQ), managerial competence (MQ), and emotional and social competence (EQ) and to explore relationships between leadership competence and IS. Design/methodology/approach – Based on 246 obtained responses to a questionnaire survey across infrastructure projects in the context of the Chinese urbanization process, the analysis of the relationships between top managers’ leadership and IS was performed using a structural equation model (SEM). Findings – Results indicate that top managers’ leadership competence, with MQ being the main determinant, followed by IQ, directly drives the entire life cycle of an infrastructure project toward accomplishing IS. Through positively influencing the moderate variable of MQ, EQ competence is found to have an indirect influence on IS. Practical implications – In terms of practical implications, the outcomes of this research will provide criteria for the selection of top managers for infrastructure projects to realize IS during the process of Chinese urbanization. Originality/value – The established SEM improves the leadership competence framework of IQ, MQ, and EQ in the respect of reflecting the context of infrastructure projects and promotes the research and development of leadership theory in the construction area

Challenges of implementing infrastructure megaprojects through public-private partnerships in Nigeria : a case study of road infrastructure

Nigeria’s infrastructure deficit, especially in transport sector is appalling. This triggered the Lagos state government to start addressing its infrastructure deficit through PPPs. The purpose of this paper is to identify the challenges at both development phase and implementation (construction) phase of PPP road infrastructure megaproject, and identify the critical success factors that actually made the project successful. The paper adopted case study approach within a mixed method paradigm employed to collect data. Semi structured interviews were used to collect data from the participants involved in the case study with a view to identifying the challenges and success factors. The identified challenges and success factors were incorporated into the questionnaire survey administered to the participants involved in the development and implementation stages of the case study. Data collected were analysed using descriptive and inferential statistics. The results of the Relative Significant Index ranking indicate that perceptions of Nigeria as a high risk economy by foreign investors, bureaucratic nature of the state government, schedule delay by administrative procedures, threat of expropriation and reluctance to tender/bid, and public/political opposition are the most highly ranked challenges experienced at development phase. The paper further identified unexpected increased quantity, bottleneck in securing execution of the federal government support agreement, resistance by residents, and problem of access to the right-of-way as the most ranked challenges witnessed at implementation (construction) phase. The results of factor analysis grouped the identified twenty two challenges into seven major factors at development phase, and grouped twelve identified challenges into four principal factors at implementation phase. The paper further identified four critical success factors using factor analysis that made the PPP project successful. These include enabling legislation with due diligence, strong commitment of both public and private sectors, strong financial package, and enabling environment and allocation of risk

Analysis of reverse logistics implementation practices by South Australian construction organisations

Purpose – A large number of benefits have been reported when reverse logistics (RL) is fully implemented in the construction industry. However, RL is yet to become common place in the construction sector, particularly in Australia. The particular sub-sector in which RL operates is small and weak and the remainder of the sector must embrace and accommodate it comfortably. Research is lacking on how to promoting RL in the construction industry. Very little has been done to identify the current practices that have the potential to promote RL industry-wide. The purpose of this paper is to identify the practices that work well in the sector, a strategy could be mapped out to promote RL to all stakeholders. Design/methodology/approach – In order to fill the above gap, the present study used a mixed method approach to gather and evaluate current practices and their potential to promote RL in South Australia’s construction industry. Practices that were identified using a comprehensive literature review were evaluated with a questionnaire survey and series of interviews involving construction professionals. Findings – The findings are that practices facilitating deconstruction is the most important, followed by practices facilitating the use of salvaged materials in new construction to promote RL in South Australia. Awareness of deconstruction benefits, challenges and procedures at the organisation level and facilities and services at industry level were associated with RL implementation. Availability of salvaged materials in the market was found to influence its use in new construction and as a consequence its demand. Designing for reverse logistics is another practice that could facilitate deconstruction and the onus of its promotion lies mainly with the designers. Research limitations/implications – This research was confined to one state in Australia. As such the generalisation to other states and other countries should be treated cautiously. Practical implications – The findings of this study can help inform the industry and its stakeholders on areas that they need to concentrate more on to make the South Australian construction industry a fully RL integrated one. To that end the authors propose some recommendations arising from the findings reported here. Originality/value – This study makes a contribution to the body of knowledge on reserve logistics within a previously unexplored South Australian context. In addition, the study provides valuable insights into the contribution of RL practices to the construction industry
