    Analysing complexities and uncertainties in indian megaprojects
    (Ceylon Institute of Builders, 2018-06) Mevada, J; Devkar, G; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGAS
    In India, the demand of infrastructure has been burgeoning rapidly owing to economic development and rapid pace of urbanization. Increasingly, the infrastructure planning and implementation strategy indicates the policy makers are leaning towards fulfilling this demand with megaprojects, having large scope and size, in terms of cost and resource requirements. The performance of these megaprojects has been dismissal with substantial time and cost overruns. The uncertainties and complexities associated with megaprojects is recognized as a major hurdle in effective implementation of megaprojects. There has been diversity of mechanisms adopted for managing complexities in Indian megaprojects. This paper analyses the case studies of Indian megaprojects to determine the types of mechanisms followed managing complexities as well as their effectiveness. Based on this analysis, the areas of improvement in existing mechanisms have been suggested, which would be help to the policy makers and ensure smoother implementation of megaprojects.

    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
