Abstract: In responding to global issues of creating sustainable development, the Indonesian government has enacted regulations (i.e. Ministry of Public Works and Housing No. 05/PRT/M/2015) on the implementation of sustainable construction in infrastructure project execution. The purpose of this paper is to evaluate the means of implementing sustainable principles in the execution of infrastructure projects in Indonesia by the main construction service providers and their partners. A lesson-learned is presented as a source of knowledge to underpin the extensive implementation of sustainable principles in the construction of infrastructure projects leading to an integrated approach in creating a sustainable infrastructure that fulfills the requirements of sustainable development.,The method used is questionnaire surveys with Indonesian construction practitioners who are working on building construction, road and bridge construction, water facilities construction and house and settlement construction.,From the results, the practices of sustainability principles by construction service providers in infrastructure project execution are imperative from the project procurement phase. The evaluation continues to the phase of construction project execution, which reveals the inconsiderable performance of sustainability indicators due to current constraints on the implementation of sustainability principles.,This research looks into the existing gaps between sustainable construction principles and their practical implementation in Indonesian infrastructure projects. This will foster a holistic approach in the practice of undertaking sustainable procurement processes, thus reinforcing project management techniques in the phase of sustainable construction project execution. This also strengthens the interrelated roles and responsibilities of project stakeholders by taking into account principles of safety, balance and the harmony of infrastructure and the environment.

Abstract: The significant increase in Indonesian construction sector activity nowadays is also influenced by government financing for infrastructure projects. Therefore, the government needs to ensure that the infrastructure projects are consistently constructed along the project life-cycle. Phases of the infrastructure project life-cycle implemented in the Ministry of Public Works and Housing consist of 1) planning, 2) selection of service providers, 3) construction processes, and 4) construction product hand-over. Data collection using three rounds of Delphi Study was undertaken to empirically test the level of implementation of the project life-cycle indicators, which are used as standards to construct infrastructure projects. The respondents of the studies came from sectors who were executing infrastructure projects in the areas of Cipta Karya , Bina Marga , Sumber Daya Air , and Penyediaan Perumahan . The results of the studies concluded that the sectors have understood and implemented most of the indicators, however, different levels of implementation have existed along with the barriers of the implementation. From the studies, profiles of the execution of infrastructure project life-cycle were provided as references for the government to evaluate the performance of the sectors, as well as to take corrective actions to improve their performance.

Abstract: As the major consumer of resources and energy, the construction industry has been at the heart of the debate on sustainable development. The Sustainable Development Goals (SDGs) provide the overarching guidance for the construction industry to promote sustainable development from environmental, social, and economic dimensions. Moreover, sustainable consumption and production (SCP) are highlighted in the SDG 12, while Sustainable Procurement (SP) focuses on promoting sustainable development through procurement processes and decisions. However, little has been written about how the construction industry could turn the challenges of SP into opportunities that promotes procurement practices in accordance with national policies and priorities. This study examines the drivers and challenges on the adoption of sustainable procurement in construction and how it impacts the achievement of SDG 12. The quantitative approach using questionnaires identified the drivers and barriers to SP implementation in construction and the SP practices contributing to the realisation of SDG 12 (Responsible consumption and production). The results confirmed that the construction industry should play a significant role in achieving the SDGs and show that construction SP practices contribute to the realisation of 9 of the SDG 12 targets. The results also suggested that governments should play a more active role in partnership with industry stakeholders and that the social and economic dimensions of sustainability deserve more attention. The value of this study is to provide construction industry stakeholder an insight into the drivers and challenges of SP and how to turn SP challenges into opportunities by adopting initiatives that consider the environmental, social, and economic impact of all procurement decisions. It also highlights the important role of the construction industry towards the realisation of the SDGs, particularly the significance of SP practices in the construction industry to the achievement of SDG 12.

Abstract: Sustainable development is the core agenda item of the 21st century to be addressed simultaneously by societies, businesses, and academia. Likewise, sustainability research in the project context is fragmented and still at a nascent stage with less attention directed towards the key antecedents particularly in developing countries. Using institutional theory, this paper analyzes the role of normative and mimetic isomorphic pressures as external enablers for integrating sustainability in project processes. Additionally, it aims to empirically validate a structural model for predictors of sustainable project management (SPM). Data were collected from 146 large construction firms in Pakistan which were then analyzed using the partial least square structural equation modeling (PLS-SEM) technique. The results show that mimetic isomorphic pressures assert more influence than normative pressures in predicting the sustainability performance of construction projects. The inferred implications suggest that large construction firms will tend to improve their sustainable performance under isomorphic pressure from professional bodies and from those competitors who are early adopters of sustainable project practices. This paper contributes to the literature by explaining the role of non-coercive isomorphism as an important enabler of SPM in developing countries. The model presented will enrich our current understanding of SPM by studying its juxtaposition with institutional theory and sustainable development research.

Abstract: The construction sector in India is in the government's intense focus on creating a world-class infrastructure balancing environmental conservation. Adopting green procurement practices by mitigating adoption barriers is necessary for Indian construction firms to achieve the goal. However, none of the existing research identified the comprehensive list of barriers, analysed their impacts on green procurement adoption, prioritized the barriers and formulated the solution strategies to mitigate them and maximize green procurement adoption for the Indian construction sector. To bridge this gap, this study has identified barriers, analysed their impact, prioritized the criticality, and developed the solution strategies to alleviate them. Questionnaire surveys and descriptive statistics are first performed for data analysis of the firms based on the firm's size and domain of expertise. Later, an analysis of variance (ANOVA) is performed and identified the significant differences in the impact of the barriers on Indian construction firms having different sizes or domains of expertise. The fuzzy best-worst method (FBWM) is then used to identify the most significant barriers as “reduced commitment from higher management”, “lack of management support”, and “perception of higher cost for adhering to green procurement”. Finally, the Delphi technique and assessment of various portals of the Government of India (GOI) have been carried out to identify the solutions to mitigate the barriers. The research results in an original and unique approach to identifying and analysing the critical barriers to green procurement adoption and their impact on different categories of Indian construction firms. It has identified the topmost barriers and then the solution strategies Indian construction firms and GOI need to focus on to embrace green procurement. The procurement managers can identify the top-rated barriers derived from the present study to closely focus and make strategies to eliminate them, helping their organisations adopt green procurement practices. The solution strategies derived from the study may be ready to implement action plans for construction and infrastructure companies of India, environmental and social development of the country, and assisting the GOI in developing and implementing the policy of green procurement for the Indian construction industry. • Green construction procurement is critical to India's sustainable economic growth. • Study identified green procurement barriers and impact on Indian construction firms. • The top critical barriers found by the fuzzy best-worst method (FBWM). • Solution strategies formulated to mitigate the barriers. • Study impacted infrastructure, environment, social sector, and policy formulation.

Abstract: Sustainability is considered to be a central part of every global policy change because of the likelihood of negative effects of particular policies on the already endangered environment and on society. Whilst sustainability is receiving significant attention in construction sectors in developed countries, this seems to be less true for developing countries. Thus, this study explores the challenges faced by the construction sector in one such developing country, Libya, in integrating sustainability practices into its common scope of activities. The study adopted a mixed research approach consisting of a questionnaire survey and expert interviews. Completed questionnaires (134 No.) were analysed using statistical techniques. The findings from the survey informed the topics for the interviews with 10 experts where the collected data were analysed through content analysis. The outcomes of the research explained that the awareness of sustainability in construction was weak in the practice of the Libyan construction sector. Additionally, the failure of supporting institutions to create an effective application of sustainability guidelines, lack of stricter legislation, building codes or standards were also found to be major challenges. The study contributed to knowledge by providing a better understanding of sustainability and clarified the main challenges faced by the stakeholders and which they have to consider in order to improve sustainable construction in Libya. The practical implications of the study include the strategies identified to avoid or minimise the challenges and their consequences.
