The target of construction of National Highways (NHs) is 15,000 km, of which 6,604 km have been completed till February in the current FY2016-17. The slow speed of construction of NHs, according to the Ministry of Road Transport and Highways, are mainly due to land acquisition, utility shifting, non-availability of soil or aggregates, poor performance of contractors, environment, forest or wildlife clearance, ROB and RUB issue with Railways, public agitation for additional facilities, arbitration or contractual disputes with contractors, etc.
There is a well-established mechanism for monitoring and testing of quality of construction and development of work of NHs by engaging a consultancy firm of international and national repute for every project to ensure quality construction, according to the Ministry of Road Transport and Highways. They supervise, monitor and conduct tests as per procedures laid down in various codes published by Indian Road Congress, manuals and MoRTH specifications for road and bridge works and National Highway Authority of India quality manuals, etc. Apart from this, field units and Quality Division of Ministry, NHAI and state PWD also conduct inspection at various project sites regularly to monitor the quality of work. Quality auditors are also engaged from time to time for conducting quality audits of the project work. On observation of any violation, action against the defaulter is taken as per provision in the agreement. The Ministry has empaneled national level project monitors for monitoring of critical and languishing NH projects all over the country.
