## ANSWER

THE MINISTER OF ROAD TRANSPORT AND HIGHWAYS

## (SHRI NITIN JAIRAM GADKARI)

(a) and (b) Damages  sustained  and  accidents  on  NHs,  including structures  thereon,  are  also  caused  due  to  various  other  reasons like  design  flaws,  non-compliance  to  Standards  /  Specifications, improper construction practices / techniques etc. apart from Force Majeure  events  like  heavy  rains,  landslides,  floods  etc.  Generally, incidents  of  extreme  rainfall  and  landslides  are  witnessed  in  the Himalayan  Region  and  Western  Ghat  sections  are  causing  large scale damages to infrastructure including National Highways (NHs) sections.

State  /  Union  Territory  (UT)  -  wise  details  of  Incidents  of collapses / major deficiencies in NHs  stretches (including in structures like  Bridges,  culverts  etc.)  reported  during  the  last  five years are at Annexure.

- (c) to (e) Based upon the learning of failures of hill slopes during construction,  Environmental  Impact  Assessment  reports  etc.,  the Government  has  taken  various  initiatives  for  developing  disaster resilient  NHs  infrastructure,  including  structures  thereon,  which includes: -
- i. Consultants to include slope studies and stabilization as part of Detailed Project Report preparation. Geological and geotechnical investigation are to be carried out covering both within and beyond Right of Way (ROW) to prevent damages to property and infrastructure. Also, due emphasis to be given for construction of catch water drains, side drains with catch pits, cut off drains, cross drainage, etc.
- ii. Implementation  of  standardized  parameters  for  investigating hill slope stability & selecting cost-effective long-term stabilization measures for landslide-prone areas in hilly regions.
- iii. Hill  construction  methodology  refined  which  mandates  initial construction  only  for  hill  cutting  &  slope  protection  and subsequent highway construction only post stabilized cutting formation and protection work.
- iv. Sensor instruments based monitoring of internal slope disturbances  has  also  been  taken  up  in  2  NHs  stretches  on pilot basis for real-time landslide monitoring systems.
- Implementation of sustainable bio-engineering measures such as  coir/jute  mat  hydroseeding,  interlinked  chain  mesh  with green  strips,  bamboo  piling  by  stepped  berms  and  erosion control with Vetivar grass plantation on jute matting etc. for stabilizing hilly and landslide prone areas, thereby enhancing
- v. safety on NHs in such areas.
- vi. Research scheme taken up through IIT Roorkee for Development  of  Guidelines  for  the  Assessment  of  Hillslope Instability Instrumentation & Real Time Monitoring
- vii. Standard Operating Procedure issued along with delegation of powers to field officers in case of notified disasters.
- application system  for  Monitoring  and  rectification  of  highway  defects which enables geo-tagging of defects along with photographs
- viii. Operationalization of a centralized monitoring for contractor's accountability.
- ix. Authority  officers  directed  for  thorough  inspection  of  NHs stretches  within  six  months  of  expiry  of  the  Defect  Liability Period  (DLP)  /  Concession  Period  to  check  enforcement  of defect rectification and maintenance status of NHs stretches. In  the  event  of  not  fulfilling  the  Contractual  obligations  by Contractor /  Concessionaire, DLP / Concession Period is also suitably extended.
