Design & Construction of Iconic Signature Bridge in Delhi

The presently under construction at Delhi over river Yamuna Signature Bridge is an iconic bridge of its kind which is languid in perpetual motion in the tradition of Calatrava’s Bridges in motion to the onlookers where very high importation of technology is involved.

The very complex geometry of the slanted steel pylon with its three dimensionally varying Indian welcoming (Namaste) pose involves high precision fabrication, machining and drilling including the trial assemblies of fabricated segments were carried out in China from economic considerations under strict vigilance and supervision.

The unprecedented nature of design of foundations, bearings and the pylon called for ingenious and first time construction engineering and methodology to be evolved whether for hybrid foundations, concrete technology, erection of large capacity and special type of bearings, fabrication, trial assemblies, welding including very long and critical in situ welding of pylon base and finally segmental erection of three dimensionally varying pylon.
