MUMBAI COASTAL ROAD PROJECT

Project Name:Mumbai Costal Road Project – Package IV
Authority:Municipal Corporation of Greater Mumbai
Client:Lombardi Engineering Group
Location:Mumbai, Maharashtra (India)
Project Overview
  • The Mumbai Coastal Road features a submerged tunnel in Package IV.
  • The tunnel consists of a 3,000 m long twin tube with two lanes and an emergency lane (expanded to three lanes during high traffic intensity).
  • It includes cross passages every 300 m and one pump shaft.
  • For excavation, a Hydro shield-TBM will be used.
  • The road is situated approximately 22 m below sea level.
  • Beneath Malabar Hill, the overburden at the crown reaches up to 70 m (along the shore).
  • The tunnel intrados has a diameter of 11 m and utilizes precast segments (referred to as “universal segments”).
  • Prefabricated, walkable technical canals are present at each invert.
  • The cut & cover intrados section measures 11 x 6.5 meters.
  • Ramps connect the project to the bridge viaducts in the north and the existing road network in the south, along Marine Drive.
About Technical Building
  • Location: The building is situated on top of a cut and cover section of LHS, with a portion integrated into it.
  • Structure Division: It is divided into two parts: one above the cut and cover box and the other housing a CNC system.
  • Purpose: The building provides dedicated electrical and mechanical services to meet the technical/engineering requirements of the tunnel beneath.
  • Levels:
    • Ground Level: Access to the technical room below and standby fire vehicles. Landscaping is proposed around and above the deck/slab. Features include a dedicated ventilation system (Saccardo Equipment), battery room, LV panel room, MV panel room, transformer room, training room, office, toilets, staircase, and approach shaft.
