New Delhi: RVNL (Rail Vikas Nigam Limited), which had been chosen by the Indian Railways to replace the century-old Scherzer’s span, designed and installed at the Pamban rail bridge to pave way for vessels to pass through, has finalised 3 international consultants to make ready the preliminary design of the new span. Pradeep Gaur, Executive Director (Project) said, 3 consultants, including 2 from the US, had been short-listed to prepare the preliminary design and they were likely to make ready the designs in the next 2-3 months, after which tenders would be called to finalise the executing agency.
- After testing the century-old bridge with his colleagues, Gaur said the existing Scherzer’s span would be replaced probably with a vertically lifting single truss span “but nothing has been finalised.”
- He added, vertical lifting single spans were being used worldwide.
- He said,“we are trying to do the best using the latest state-of-the-art technology and want people to have a feel that good job has been done.”
- He said,The new span should also serve for more than 100 years.
- He said,“The span is inherently not safe and we will do the best while replacing it.”
- Gaur said, after finalising the tender process, the fabrication work would begin in 6-8 months.
- He said, it would take one to one and a half years to complete the work.
- He said, after the installation of the new span, speed of trains on the bridge could be considerably enhanced from the present 15 km/ph.
