India being one of the fastest growing economies in the world is witnessing transformative changes in terms of public investment, private consumption & structural reforms leading construction sector to reach $1.4 trillion by 2025. Coupled with rapid urbanization, climate change & Nationally Determined Contributions (NDCs) in terms of reduction of emission intensity by 30-35% by 2030, to achieve net zero emission by 2070, the business-as-usual approach for building the urban infrastructure including housing need to superseded by cutting-edge innovative & productive technologies nurturing fast-track, affordable, sustainable & resilient growth. The ubiquitous conventional construction practices of cast in-situ brick & mortar, RCC construction shall have to be replaced by industrialized building systems comprising of off-site construction techniques such as precast concrete construction, prefabricated steel construction, customized formworks, sandwich panels, 3D printing & PPVC supplemented by digitalization, BIM, cloud computing, construction robotics etc.

To bring perceptible changes the way we build, Ministry of Housing & Urban Affairs (MoHUA), Govt. of India with BMTPC as technical partner conceptualized & organized Global Housing Technology Challenge- India (GHTC-India) through which 54 new construction systems which are time tested & proven globally are identified as potential future building technologies for the country & being promoted across the country. The six light house projects were also undertaken under PMAY-U to showcase the effectiveness of these systems & adapt them for further replication.

In order to build capacities and for better outreach & wider advocacy amongst building professionals about the new and emerging building materials and technologies for construction, MoHUA along with SPA, New Delhi & BMTPC introduced an online certificate course on Innovative Construction Technologies entitled NAVARITIH (New, Affordable, Validated, Research Innovation Technologies for Indian Housing).

As regards, innovative systems, information is available in bits and pieces and there are no textbooks available summarizing all these systems & therefore, the reading material in form of book for the course was prepared & published as first edition of the book. The experts from industry, academic institutions & research laboratories have contributed various chapters of the book. In addition, information from various resources have been collected and compiled in concise form to develop the book. The second edition of the book contains updated information along with few new chapters since the last publication. The book is a collection of technical information available on technologies worldwide and it is the first of its kind on the subject. We are sure, it will help the readers to comprehend these innovative systems and implement them in their future construction projects.
