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 22nd September, 2015 by the team comprising IE (TL,

B/SE, SQME.QS, AHE-2, ABE-2, AQME-2 and Survey Engineer); the Representative of NHAI,

and EPC Contractor were present during site Inspection. The visit was started from Km 115

+000. As there is virtually no Road work at site, some structural works are in progress. The

inspection program started at 10:30 AM and concluded at Km 45 +000 on the same day at

5:30 PM.

III. FINDINGS IN JOINT SITE INSPECTION

There is virtually no highway work due to rain, except dumping of sand/sandy soil in some

location and GSB, WMM and DBM work in some stretches during dry spell. Some structural

works like piling works of ROBs, return walls of box culverts and concreting work of RUB are

in progress, but work progress is very slow (Snail speed) due to rain. 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. Project Information Board/Safety Boards

Information board at the end of the Project Highway has been installed and corrections in the

information board installed at starting point of the project Highway has been done after long

time.

Some safety and direction boards are installed at some places which are not sufficient. EPC

Contractor is advised to install more safety boards, use safety tapes at work site and cordon

work area to avoid accidents

2. Box Culvert (Km 115+020) RHS

Full width of this culvert is already constructed except return walls. During joint Inspection; it

has been observed that the box of the culvert is totally inundated under water by the flood in

this monsoon. The opening of the culvert seems to be insufficient to cope with HFL.

Therefore, Concessionaire is advised to seek advice of the designer and Hydrologist of IE and

the Concessionaire for the solution of this problem.
