Abstract: – The purpose of this paper is to identify and assess the perceptions of stakeholders on critical success factors (CSFs) for Public Private Partnership (PPP) projects in Nigeria. – A comprehensive literature review was conducted to identify the CSFs for PPP projects, which were employed to design a questionnaire survey. In order to capture a broad perception of stakeholders, the questionnaires were administered to five different stakeholder organisations involved in different PPP projects implementation in Nigeria. Data collected were analysed using descriptive statistics, mean score, Kruskal-Wallis test, analysis of variance (ANOVA), and factor analysis. – The study revealed the result of mean score ranking, which indicated that all the stakeholders considered the identified 26 CSFs important and crucial for the successful implementation of PPP projects in Nigeria. Thus, the results of Kruskal-Wallis test and ANOVA indicated that except for six (out of 26) identified CSFs, there is no statistically significant difference in the perceptions of the stakeholders on CSFs for PPP projects in Nigeria. The study, through factor analysis, grouped the 26 identified CSFs into six principal factors. – This research would be of benefit to stakeholders in PPPs to be aware of CSFs that demand utmost consideration. Also the identified CSFs are expected to enhance the success rate of PPP projects. – The findings would be useful for PPP stakeholders in making decisions and in implementing PPP projects towards achieving value for money. This research will also be of interest to other academic researchers intending to investigate CSFs for PPP projects in other locations.

Abstract: – 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. – 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. – 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. – This research was confined to one state in Australia. As such the generalisation to other states and other countries should be treated cautiously. – 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. – 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.

Abstract: – Studies on barriers to public private partnerships (PPPs) in Nigeria, especially those that are empirical, remain rare. Thus, the purpose of this paper is to identify and classify barriers to PPP projects implementation in Nigeria. – Primary data were collected through the administration of questionnaires to public sector authorities, concessionaires, local lenders, consultants, and contractors already involved in PPP projects. Data collected were analysed using descriptive statistics, mean score, Kruskal-Wallis test, and factor analysis. – The study identified 58 barriers and the analysis of the total ranking among stakeholders revealed that all the identified barriers were considered as serious barriers influencing PPP projects in Nigeria. The result of Kruskal-Wallis test indicated that except for 18 (out of 58) identified barriers, there was no statistical significant difference in stakeholders’ perceptions on barriers to PPPs project implementation in Nigeria. The study through factor analysis grouped the identified 58 barriers into ten principal factors with their components. – This study provides an in-depth understanding on Nigeria’s PPP market environment current context in terms of prevalent barriers influencing PPPs project. This would be beneficial to PPP stakeholders in decision making and planning towards PPP projects implementation. – The findings would be valuable in assisting all stakeholders, particularly potential local, and foreign private investors to recognise major barriers in the implementation of PPP projects in Nigeria and thus helping them to develop strategies for penetrating Nigeria and developing countries PPP market successfully. This study results are crucial as not many empirical studies have been conducted in Nigeria.

Abstract: Despite the envisaged benefits of BIM adoption for SMEs, BIM in SMEs has remained an underrepresented area within the available academic literature. This study proposes and draws upon a framework grounded on innovation diffusion theory (IDT) to provide an illuminating insight into the current state of BIM and the main barriers to BIM adoption within Australian SMEs. Based on analyses of 135 questionnaires completed by SMEs through partial least squares structural equation modelling (PLS-SEM) and grounded on the proposed framework, the current state of BIM adoption and barriers to BIM adoption for SMEs are discussed. The findings show that currently around 42% of Australian SMEs use BIM in Level 1 and Level 2 with only around 5% have tried Level 3. It comes to light that lack of knowledge within SMEs and across the construction supply chain is not a major barrier for Australian SMEs. In essence, the main barriers stem from the risks associated with an uncertain return on investment (ROI) for BIM as perceived by key players in SMEs. The findings also show the validity of the framework proposed for explaining BIM adoption in Australian SMEs.
