## ANSWER

## THE MINISTER OF ROAD TRANSPORT AND HIGHWAYS (SHRI NITIN JAIRAM GADKARI)

(a) to (f)   As per information provided by the executing agencies of the National Highways (NHs), major deficiencies/ damages in NH stretches have been reported for 67 projects / stretches in the last three years and current year.  State / Union Territory (UT) - wise details of major deficiencies/ damages on NH stretches including NHs in the State of Odisha observed in the last three years and current year along with status of its rectification works and action taken against contractors, concessionaires,  consultants  etc.  are  placed  at  Annexure-I.  Actions against defaulting agencies have been taken up as per the provisions of  the  Contract/  Concession  agreement  in  cases  of  deficiencies/ damages,  such  as  termination  of  contract  agreement,  levying  of penalties/  liquidated  damages,  debarment/  blacklisting,  declaring  as non-performers etc.

Action taken against Contractors/ Concessionaires for noncompliance  of  maintenance  obligations  in  NH  works  in  the  State  of Odisha in the last 5 years and current year is placed at Annexure-II.

Development and maintenance of NHs is a continuous process. All  efforts  are  made  to  ensure  that  the  NHs  are  constructed  as  per stipulated  quality  standards  specified  in  the  Indian  Roads  Congress (IRC)  specifications  and  codes.  To  ensure  that  highway  construction adheres to stipulated quality standards, Consultants (Authority's Engineer/ Independent EngineersAE/IE) are appointed by the executing  agencies  for day-to-day supervision of works  at site. Officials  of  executing  agencies  undertake  inspections  from  time  to time and ensure adherence of conformity of quality of the work done by the Concessionaire/ Contractors with stipulated requirements.

NHs development projects are executed on mainly three modes i.e.  (i)  Build  Operate  and  Transfer  (BOT),  (ii)  Hybrid  Annuity  Model (HAM)  and  (iii)  Engineering  Procurement  and  Construction  (EPC),  for which design and maintenance responsibilities as per project scope is vested with the Contractor/ Concessionaire.

The Government has prioritized the maintenance of existing NHs network  and  inter-alia  evolved  a  mechanism  to  ensure  Maintenance and Repair (M&R) of all NHs sections through accountable maintenance  agency.  Concession  period  including  maintenance  for projects on BOT is 15 to 20 years and on HAM is generally 15 years. Concessionaire is responsible for maintenance of the respective NHs stretches within the concession period of the project. Only in case of EPC  projects, Defect Liability Period (DLP) is 5 years for the bituminous  pavement  works  and  10  years  for  concrete  pavement works. For Toll-Operate-Transfer (TOT) and InvIT (Infrastructure Investment Trust) projects, concession period including maintenance is 20 to 30 years. Concession period for Projects on Operate, Maintain and Transfer (OMT) is generally 9 years.

For  all  remaining  sections  of  NHs  stretches,  where  DLP  has ended  or  is  not  under  any  concession  period  of  BOT/HAM/TOT/InvIT project, Government has taken a policy decision to undertake maintenance works through Performance Based Maintenance Contract (PBMC)  or  Short  Term  Maintenance  Contract  (STMC).  While  STMC works  are  generally  undertaken  for  a  contract  period  of  1-2  year, PBMC works are undertaken for a contract period of about 5-7 years.

Remedial work to repair or reconstruct damages during construction or in the Defect Liability Period (DLP)/ Concession period is  the  responsibility  of  the  Contractor/  Concessionaire  at  their  own cost  as  per  provisions  of  contract  agreement  except  in  those  cases where the Contract Agreement has been terminated in which case the securities provided are forfeited.

following in

The Government has additionally taken the initiatives for improvement of quality control systems implementation of NHs works: -

- i. Adoption of Automated & Intelligent /Machine-aided Construction (AI-MC) in NH projects;
- ii.      Assessments  of  road  conditions  through  Network  Survey Vehicle (NSV) mandated for all NHs and Expressway works at the time of  completion  and  every  six  months  thereafter,  which  is  monitored through electronic platform. NSV system for road condition assessment  has  been  revamped  using  analytics  for  enforcement  of contractual provisions during Operation and  Maintenance  (O&M) through dedicated central cell;
- iii.     Operationalization of a centralized system called NHAI One App for Monitoring and rectification of highway defects which enables geo-tagging of defects along with photographs;
- iv.     Analysis  of  High-Resolution  Imagery  collected  from  Drone Surveys in Drone Analytics Monitoring System (DAMS) integrated with Artificial Intelligence/ Machine Learning algorithms for periodic evaluation of progress and quality of ongoing NHs works from time to time;
- v.     Deployment of Mobile Quality Control Vans (MQCVs) equipped  with  Non-Destructive  Testing  Equipment  on  pilot  basis  in four States, namely in Gujarat, Rajasthan, Odisha and Karnataka, for diagnostic assessment of overall health and quality of works from time to time during project implementation phases;
- vi.    Deployment of Third-Party Quality Auditors for independent quality audits of NH works on a case-to-case basis;
- vii. Action initiated for Contractor/Concessionaire Rating System for NH projects aimed at creating transparent mechanism for evaluating performance of contractors/ concessionaires based on key parameters, such as, timely completion, Quality of work, Maintenance performance, Safety compliance, Dispute management, Subcontracting practices etc.
