BACKGROUND
Article 13, clause no. 13.2 of the Concession Agreement states that:
13.2 Inspection
“During the Construction Period the Independent Engineer shall inspect the Project
Highway at least once a month and make a report of such inspection (the “Inspection
Report”) stating in reasonable detail the defects or deficiencies, if any, with particular
reference to the Scope of the Project and Specifications and Standards. It shall send a
copy of the Inspection Report to the Authority and the Concessionaire within 7 (Seven)
days of such inspection and upon receipt thereof, the Concessionaire shall rectify and
remedy the defects or deficiencies, if any, stated in the Inspection Report. Such
inspection or submission of Inspection Report by the Independent Engineer shall not
relieve or absolve the Concessionaire of its obligation and liabilities hereunder in any
manner whatsoever”.
To comply with the requirement of the above clause of Concession Agreement, a Joint Site
Inspection program of the Project Highway was planned for 22-10-2015 by a joint team
comprising IE and EPC Contractor and the same was informed to the Concessionaire vide this
office letter ref. no. LASA/BK/IE/73426/2015-1047, dated 16/10/2015. During site Inspection,
whole team of IE, Representative of EPC Contractor Mr. Veer Naidu (Project Manager), Mr. V.
Ratnam (Deputy Project Manager, Highway), Mr Adi Narayan (Material Engineer) and other
site engineers were available during site Inspection. Concessionaire’s representative did not
join the Joint Inspection. This Joint Site Inspection Report is based on the findings during site
inspection by the whole team of IE (TL, B/SE, SQME, QS, AHE-2, ABE-2, AQME-2 and
Survey Engineer).
Project Brief
The NH-34 Barasat to Krishnagar Section in the state of West Bengal is located in the
northern part of Metropolitan city Kolkata. It is part of the proposed Barasat to Raiganj section.
The NH-34 is an integral component of the National and Regional road network. The project
highway described in this report is under construction and runs from Km 31.000 to 115.000
between Barasat to Krishnagar on NH 34 in the state of West Bengal.
The completed NH-34 will connect the traffic from Kolkata to Siliguri as well as facilitating the
movements between the State highways (SH), Major district roads (MDR) and other district
roads (ODR). The increase in car ownership, changes in land use and travel patterns have
resulted in congestion on many parts of the State road network including NH-34. The NH-34
currently not only functions as a main corridor to Nepal and Bangladesh but as an urban
collector/distributor between communities, employment and shopping centres.
The alignment traverses through two Districts: North 24 Parganas and Nadia. The terrain
along the project road is generally plain. The predominant land use along the project road is
agricultural with ribbon development near human settlements. At certain locations,
encroachments within the ROW have been observed in the form of Shops, Hotels, Dhabas
and various other commercial establishments. The road passes through towns of Santoshpur-

II. SITE INSPECTION
Joint Site inspection was conducted on 16th October, 2015 by the team comprising IE (TL,
B/SE, SQME.QS, AHE-2, ABE-2, AQME-2 and Survey Engineer); and EPC Contractor were

III. FINDINGS IN JOINT SITE INSPECTION
There is virtually no highway work due to lack of approved borrow area, except dumping of
sand/sandy soil in some location and GSB and WMM work in some stretches and DBM work
in very few stretches. Some structural works like piling works of ROBs, return walls of box
culverts and pushing of Tunnel at RUB are in progress. Work progress is very slow. The
compliance of comments given by the Independent Engineer in the Reports of previous Joint
Site Inspections was reviewed during this inspection. The works which are under progress
were inspected. The following are the findings:
1. Box Culvert (Km 113+980) RHS
