## ANSWER

THE MINISTER OF STATE (INDEPENDENT CHARGE) OF THE MINISTRY OF HOUSING AND URBAN AFFAIRS

(SHRI HARDEEP SINGH PURI)

(a):   Yes Madam. A Technology Sub-Mission (TSM) under  Pradhan Mantri Awas  Yojana  (Urban)  {PMAY(U)}  Mission  has    been  set  up  with  the objective of providing 'Sustainable Technological Solutions for Faster & Cost Effective Construction of Houses suiting to Geo-Climatic and Hazard Conditions  of  the  Country.' Towards  expediting  the  housing  delivery process for meeting the target of 'Housing for All by 2022', the Ministry of Housing  and  Urban  Affairs  is  actively  promoting  the  use  of  prefab technologies in housing construction under the overall purview of TSM.

- (b)     Hindustan Prefab Limited (HPL), a Government of India Enterprise, under the aegis of the Ministry of Housing and Urban Affairs has reported that  prefab  construction  is  one  of  the  options  which  can  help  in addressing  the  housing  shortage  of  the  country  through  provision  of quality housing in lesser time.  Off site construction involving manufacturing  of  building  component  in  factory  and  installation  at  site also  helps  in  reducing  dust  pollution  and  optimizes  use  of  natural resources  as  the  prefab  component  are  generally  lighter  than  the conventional technologies.
- (c)       HPL  report  states  that  use  of  prefab  technologies  considerably reduce the time of construction which is normally 50% to 60% lower than the conventional system of construction.  There are various technologies which enable small houses to be fully constructed in factory with basic services and assembled at site in a very short span of time.  A 10 stories building in Mohali was  also erected within 48 hours using steel construction technologies.
- (d)        The  Government  of  India  has  been  promoting  the  use  of  prefab technologies  extensively  to  all  stakeholders.  In  the  recently  published National Building Code (NBC) 2016 by Bureau of Indian Standards (BIS), the  provisions  have  been  updated  to  ensure  utilization  of  number  of prefab building materials and technologies to provide for innovation in the field  of  building  construction.  Updated  provisions  on  new  alternate technologies  for  speedier  construction  have  also  been  included  in  the NBC 2016.

Building Materials & Technology Promotion Council (BMTPC) has so far identified 16 emerging technologies and building materials for faster and quality construction of houses. List of the technologies identified by BMTPC  is  at Annexure-I.  Central  Public  Works  Department  (CPWD)  has published  Schedule  of  Rates  (SoR)  for  seven  technologies  towards promoting use of these technologies. List of the technologies for which SoR has been published is at Annexure-II.

Hindustan  Prefab  Limited  (HPL)  has  also  developed  a  Housing Technology Park at Jangpura, New Delhi showcasing alternate housing construction prefab technologies, which could be utilized for construction of housing units.  The technology park provides stakeholders an option to assess  and  compare  all  the  technologies  for identifying  the  most appropriate  technologies  for  their  respective  use.  BMTPC  and  HPL  is organizing Sensitization/Capacity Building Programmes in various States on  prefab  and  emerging  technologies  in  order  to  create  confidence amongst the architects, engineers and other stakeholders.

The  Government  of  India  has  recently  announced  to  organise  the 'Global  Housing Technology Challenge-India (GHTC-I)' in 2018-19 in  the World  Urban  Forum  (WUF),  2018    at  Kuala  Lumpur,  Malaysia.  The  main objective of the challenge is to explore innovative technologies for mass housing  which  would  bring  paradigm  shift  to  housing  construction scenario  that  is  cost-effective,  fast,  safe,  sustainable  and  adaptable  to suit different geo-climatic conditions of the country.
