Design Aspects Of Barapullah Elevated Corridor Ashish SRIVASTAVA Dy. Principal Consultant Tandon Consultants Pvt Ltd New Delhi ashish.srivastava@tcpl.com
Ashish Srivastava is a structural engineer with expertise in designing of infrastructure projects including bridges, viaduct, flyovers, underground structures and metro projects. He has been associated with design works of several prestigious and challenging projects, many of which have received appreciation and awards for innovation, aesthetics and use of design concepts suiting to project requirements.
Summary Barapulla Elevated road was constructed to provide mandatory link for athletes and officials between Games Village and Jawahar Lal Nehru Stadium for the Commonwealth Game-2010 held in Delhi. The 4.5Â km long viaduct consists of 2 separate structures of 10 m width each for the up and down traffic. The project traverses along the Barapulla Nalla & lies in close vicinity of historical monuments viz. Tomb of Khan-e-Khana at Mathura Road & Monumental arch bridge near railway tracks at Mathura road. It also crosses major road & railway crossings which required cantilevering of structures for Barapulla Elevated Road to ensure that the construction of elevated corridor did not require slowing or shutting down the traffic below. The innovative design concept was geared for high speed construction (time available: 20 months) using precast prestressed

segmental techniques (no. of segments 3000) including many large obligatory spans (upto 85.0 m). Decreasing the expansion joints in the deck by providing integral constructions led to increased riding comfort. This project is one of the most ambitious projects taken in India within very tight time constraint. Present paper details the various aspects of the project including the design innovations which resulted in construction to be completed within the timeline.
