Remarks :
  • ROB was constructed at the location of existing level crossing. The frequency of closing / opening of gate was about 2 to 3 minutes. The site is falls in the busiest area of Nalasopara town and Road connecting to National Highway with shops running on either side.

  • The site of work was not continuously available due to limited space and time restriction for working. There were number of overheads and unforeseen under ground services like water supply, sewage line, telephone and electrical cables etc., encountered during work. This required utmost care was taken to keep the services uninterrupted.

  • The work close to Railway Track has to be done with utmost safety.

  • Superstructure work consisting of continuously RCC solid slab, RCC voided slab. The same were carried out in monsoon under extremely heavy traffic condition.

  • Reinforced earth work was carried out with the help of Geogrids and Precast Facia.
