Share with your network

The Covid-19 pandemic has impacted construction activity. However Team DFC has in an innovative out-of-box approach initiated work on the Valsad Road Over Bridge (ROB) in Gujarat state on the Western DFC. Working in tandem with various Government agencies and the Civil administration, the ROB which funnels busy traffic into Valsad ROB from the Mumbai-Delhi highway, a 20 day traffic block was secured on 02.06.2021 for dealing with this challenge.

  • Work in Western DFC’s Vaitarana–Sachin section of Western faced a bottleneck of crossing a ROB near Valsad Town in South Gujarat.
  • The ROB work could not be started due to various limitations and track laying activities would have been adversely affected.
  • Track laying projects using state of the art New Track Construction (NTC) machine, would have been affected.
  • The project team geared up to take up this challenge.

Innovative solutions proposed:

  • After any brainstorming sessions, an innovative solution was arrived at.
  • The solution proposed was to insert a Twin precast box of 16m x 10msize on the approach of the ROB to take the NTC forward through it.
  • The biggest challenge in doing this work was the road traffic block, as this ROB is one of the busiest passages into the city of Valsad from Mumbai-Delhi highway.
  • The whole work is planned to be completed in 20 days road traffic block.
  • Extensive arrangements were made for precasting these huge segments.
  • Despite lock-downs and travel restrictions, a team of approximately 150 nos, including senior engineers toiled day & night to finish the casting works.
  • Road traffic block was granted by the district administration of Valsad, responding favorably to the proposal.
  • The road traffic block of 20 days commenced on 02-06-2021 and the work is progressing as per planning.
  • Four heavy duty hydraulic cranes having capacity varying from 300 MT to 500 MT are mobilized for the installation of these segments.
  • Another challenge that was difficult to handle was solved by innovation in local handling of the segments.
  • The precast segments are too big & heavy to handle without causing any internal stresses during handling.
  • The Project Team has designed a special carrier using a multi-axle trailer fitted with a steel platform on it.
  • The fabrication of the steel platform was completely done at site even during the period when the industrial oxygen supply was prohibited in the country.
  • The team could overcome all such constraints by continuously striving for alternatives and by taping the collective wisdom & experience of the team.
  • DFCCIL officials stated that they are hopeful of completing the works within the traffic block period.
  • The officials shared profound happiness in the way project execution team is performing during the trying times of this pandemic.
  • When the NTC track laying machine wheels forward from the North end of Valsad ROB to the South end, it is another firm step towards the commissioning of DFC, one of the largest infrastructure projects of modern India.
