“…It could help reveal unique perspectives on the problem domain and suitable to collect more detailed answers from interviewees. In line with a similar study performed by Oliveros-Romero and Aibinu (2019), the expert survey was selected as the appropriate research method to obtain comprehensive opinions from the limited number of LCA professionals representing the abovementioned five stakeholders' categories after evaluating several optional research methods.…”

PurposeDespite the desire to improve the sustainability of the construction industry, Sri Lanka is still plagued by the low-level adoption of essential methods such as Life Cycle Assessment (LCA) in building and infrastructure delivery. It is indispensable to investigate enablers for facilitating LCA because identification of enablers is a crucial step in the implementation of LCA. This study aims to analyze internal and external enablers for facilitating LCA for the Sri Lankan construction industry from the perspective of five stakeholder categories (academia, government, construction industry, society and environmentalists) and also aims to develop strategies to strengthen the enablers.Design/methodology/approachAn explanatory research design was used. The five stakeholder categories identified above, whose contribution is essential for implementing LCA in Sri Lanka, were selected for data collection. A total of 20 semi-structured interviews were held representing each stakeholder category. The Repertory Grid Interview (RGI) technique was utilized and data analysis was performed using content analysis.FindingsThe results revealed that “ability to identify opportunities for environmental improvements as an extremely important internal enabler for all stakeholder categories” and “the positive growth in the country to achieve environmental sustainability”, “the availability of standardized LCA guides and handbooks” as extremely important external enablers for all stakeholder categories for facilitating LCA in the Sri Lankan construction industry. Further, strategies including making people aware of the LCA concept and development of the LCA database, etc. were proposed to strengthen the enablers.Practical implicationsKnowledge generated through this study would enable the abovementioned stakeholders to make informed decisions to promote the implementation of LCA in the Sri Lankan construction industry. Further, the results of this study have raised awareness of the issues that Sri Lanka will need to solve to expand the LCA applications.Originality/valueSo far, research on LCA has not looked into enablers that can facilitate the implementation of LCA in the Sri Lankan construction industry. This research provides a comprehensive view of the internal and external enablers for facilitating LCA from the perspective of five stakeholder categories and identifies enablers that led the abovementioned stakeholders to pursue the implementation of LCA in the Sri Lankan construction industry. The study also proposes strategies for strengthening the enablers.

“…There are no explicit mechanisms to ex-post evaluate a PPP. Oliveros-Romero and Aibinu (2019) suggest that PPPs have no formal ex-post evaluations in practice, and in their study participants (practitioners and experts) cannot recall any instrument for doing so. However, the relevance of conducting these evaluations is also explicit in the literature.…”

PurposeThis study aims to develop an ex-post impact evaluation method for public-private partnership projects (PPP) that addresses one of its main difficulties: the multiplicity of perspectives and stakeholders that exist in these projects.Design/methodology/approachThis study first developed a conceptual evaluation framework called ‘Project Success Evaluation Pyramid Model’ (PSEPM) that was designed using a Design Science approach. Second, an impact evaluation method was designed based on the PSEPM. This evaluation method was tested and refined using three PPP projects. This article presents the refined conceptual model PSEPM, the evaluation method and one of the three tests: the PPP toll road.FindingsThe impact evaluation method describes how to evaluate the impact of an existing mega project from the perspective of multiple stakeholders and isolate the impact of the procurement method. Its application in practice is demonstrated with a PPP toll road project in Chile, in which 11 stakeholders were identified. Issues such as city segregation, deficient business model, the relevance of infrastructure availability, and deficient service-fee strategy were identified in the project. The evaluation method provides a judgement about the use of the PPP procurement method and about the overall impact of the project, reconciling the stakeholder perspectives.Originality/valueThe use of this approach could give greater clarity and legitimacy to the discussion over the use of PPPs by evaluating existing projects beyond the use of traditional time and cost measurements. Its originality is the systematic recognition and identification of stakeholder motives, purposes, and judgements over a project.

“…Credit risk [37]: Both parties should implement the contract according to the contract. The credibility and credibility of the parties to the cooperation are, to a certain extent, the key influencing factors for the success of the integrated corridor project [16,38], based on the relevant credibility evaluation indicators, A comprehensive credit assessment provides a reliable credit basis for the smooth operation of the project.…”

The application of PPP mode in urban underground utility tunnel project has been vigorously promoted and popularized in China. However, the degree of project promotion varies greatly in different regions, and the enthusiasm of social capital to participate in projects varies. In essence, the impact of project risks cannot be ignored. Using the fault tree model to analyze the factors that affect the risk of PPP mode in the urban underground utility tunnel project, and obtains five factors which have great influence on the risk of the project, such as the demand for corridor entrance, revenue, financial capacity, imperfect legal system, land expropriation and historical legacy. Considering the different economic development strengths of different regions, the adaptability of PPP projects is different. Through the empirical analysis of improving the correlation degree, the conclusion is drawn that the application of PPP model in underground comprehensive pipeline corridor is more suitable for developed areas.
