    A review of drivers of sustainability in mega infrastructure projects: An institutional approach.
    (2022-06-24) Thounaojam, N; Devkar, Devkar, G; Laishram, B; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGAS
    The need for sustainable practices in megaproject implementation is becoming acute. With the ongoing progress and expansion of mega infrastructure projects (MIPs), a lot of attention has been attracted among policymakers and researchers due to their enormous impacts on the economy, society, and the environment. Given the complexity of MIPs and the sustainability-related challenges it faces; the successful management of sustainability-related targets requires influence from the institutional forces (regulative, normative and cultural-cognitive). However, existing research on the institutional drivers that can effectively promote the sustainability of megaprojects has been largely unexplored and calls for attention. Therefore, this study aims to present a review of what drives the adoption of sustainable practices in MIPs. A systematic literature review was conducted based on a combination of keyword search in the Scopus database. Using the lens of institutional theory and deductive approach, 11 drivers for sustainability in MIPs were identified from reviewing 33 selected peer-reviewed articles. This study would enhance project stakeholders’ and policymakers’ understanding of drivers for sustainability and help further improve policies, strategies, norms and culture to support MIPs in contributing to sustainable development goals.

    Sustainability practices implemented in the Indian construction industry: a focus of construction phase
    (Ceylon Institute of Builders - Sri Lanka, 2023-07-21) Thounaojam, N; Devkar, G; Laishram, B
    The construction industry is crucial to the global economy, significantly contributing to local economies and their overall productivity. This is evident in India also, where the construction sector has substantially driven economic growth and development. However, as this industry grows, it poses a significant risk to environmental degradation. While sustainability in construction industry is often investigated from the perspective of design and planning phases, there is also growing recognition of the importance of addressing sustainability during construction phase. A quantitative approach was utilised to investigate the degree to which sustainable practices during construction phase (SPCPs) are implemented in India. Data was gathered from clients, contractors, and consultants, and 40 responses were obtained from 147 respondents contacted. The level of implementation of SPCPs was ranked, and analysis of variance (ANOVA) was conducted to test the significant difference in perceptions among the three groups of respondents. The results indicated that five most frequently implemented SPCPs are: (i) health and safety inspection and auditing; (ii) health and safety training and education; (iii) preservation of archaeological sites, vegetation, and trees; (iv) construction equipment/machinery handling and utilisation strategy and (v) quality management systems. Some of the other fundamental sustainable practices that are under-implemented are: (i) construction noise/ vibration reduction measures; (ii) preassembly or off-site fabrication; (iii) sustainability assessment and recognition program and (iv) stormwater and greywater management plan. Findings of this study can provide guidance to construction industry practitioners in identifying areas that require enhancements, thereby fostering a collaborative approach towards advancing sustainable development goals
