Delhi-Gurgaon, NH-8

Detailed Engineering Design and Construction Assistance Services for Conversion of Delhi-Gurgaon Section of NH-8 into an access controlled 8/6 lane highway from Km 14.30 to Km 42.00 on BOT basis, Length- 28 Kms, India

A multimillion-Rupee fast track Design/Construction supervision Project for Conversion of Delhi Gurgaon Section of NH-8 into an Access Controlled Eight/Six Lane Expressway with service lanes along certain sections and strengthening and widening of the existing lanes from Km 14.30 to Km 42.00 falling partly in Delhi and partly in Haryana. The project is part of the Golden Quadrilateral, which links the four Metropolitan cities of India. The NH-8 links Delhi with Mumbai.

The project road is experiencing 1.45 lac PCUs per day and is thus a fit case for widening as the existing 6/4-lane road is of low capacity for this high intensity traffic. The objective is to enhance the carrying capacity of the road and provide a smooth and uninterrupted traffic flow of high speed by grade separating the intersections, doing away with signals and controlling access. The project is developed on a build, operate and transfer basis and the Concessionaire for the project is Jaypee DSC Ventures Limited working for the National Highways Authority of India. There are 9 flyovers and 3 underpasses on the project stretch. The total length of elevated roadway (flyovers) adds to of 8.4 kms. The project faces many challenges just to mention a few the tight schedule; the project is to be completed in 24 months with 6 months for design and 18 months for construction. The other challenge is unimpeded flow of traffic during construction. Many VIP’s travel the route so the security measures have to be in place throughout the construction period.Some of the bridges are:
