TL;DR: In this paper, the authors evaluate the means of implementing sustainable construction principles in the execution of infrastructure projects in Indonesia by the main construction service providers and their partners, and a lesson-learned is presented as a source of knowledge to underpin the extensive implementation of sustainable principles in infrastructure projects leading to an integrated approach in creating a sustainable infrastructure that fulfills the requirements of sustainable development.
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.

TL;DR: In this article, the Delphi study was used to evaluate the performance of infrastructure projects in the areas of Cipta Karya, Bina Marga, Sumber Daya Air, and Penyediaan Perumahan.
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.

TL;DR: In this paper, the role of normative and mimetic isomorphic pressures as external enablers for integrating sustainability in project processes is analyzed using institutional theory and empirically validated a structural model for predictors of sustainable project management (SPM).
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.

TL;DR: This is the first study of its kind to investigate the improved sustainability performance of recycled plastic aggregates from a LEED point of view and will enable developers to maximize the financial and environmental benefits of their buildings through the reduced lifecycle cost and the enhanced LEED score.
Abstract: Decreasing the demand for natural aggregates is doubly justified by the significant contribution of the construction industry to the unsustainable development path of the natural environment, and the projected global increase of the consumption of construction aggregates. Extensive research has been carried out on the physical and mechanical properties of concrete which incorporates plastic as aggregates; yet, no single study has been able to draw on structured research which demonstrates the improved sustainability performance of plastic-based aggregates to support sustainable development in the construction industry for a project seeking Leadership in Energy and Environmental Design (LEED) certification. The goal of this research is to explore the potential benefits that green processed lightweight aggregates (PLA) can provide to a project seeking LEED certification in accordance with the requirements of LEED v4 for Building Design and Construction. The objectives are to: (1) determine which LEED credit requirements can be met through using the studied material; (2) provide a comprehensive analysis of the applicable attainable LEED credits, given the existing technical information of the selected material, and (3) provide guidelines to maximize further credit attainment. To this end, the findings indicated that the use of PLA as a total replacement for coarse aggregates in lightweight concrete applications would contribute to earning directly up to 8 points (out of 110 total points) towards LEED certification. Such significant number allows for the potential increase of the project’s certification by one level. This is the first study of its kind to investigate the improved sustainability performance of recycled plastic aggregates from a LEED point of view. Moreover, the guidelines provided by the research will enable developers to maximize the financial and environmental benefits of their buildings through the reduced lifecycle cost and the enhanced LEED score. This research should encourage project teams to incorporate the knowledge of sustainable practices, and play an active role in sustainable development.
