Tunnels & Underground Spaces

Underground structures and tunnels are becoming inevitable in metropolises due to limitations in urban spaces. The underground structures department has been established to provide engineering services such as designing, consulting and
supervision on construction of tunnels, subway lines, stations and deep excavations.

This department provides engineering services for:


  • Urban Tunnels
  • Subway and Underground Spaces
  • Road and Railway Tunnels
  • Utility Tunnels
  • Hydraulic Tunnels
  • Electrical, Mechanical and ITS
  • Urban Tunnels

  • Deep Excavation

List Of Tunnel Projects

Population growth and limits of urban areas are the most important reasons to construct high rise buildings. Providing enough parking spaces for these structures raises the need for deep excavations.
Excavation with stable slopes is not always possible and, hence, the vertical trenches with supports are inevitable. Supports for these trenches include: nailing, soldier piles, anchoring and micro piles.

Our experienced experts have involved deep excavations in design and supervision of many projects for trench supports with different systems. Some of the projects of this department are:

  • Narges Commercial-Official Complex
  • Baran Commercial-Official Complex
  • Yas Commercial Complex
  • Eram (Mahestan) Commercial-Office Complex
  • Delgosha Commercial Complex
  • Vanak Commercial-Office Complex
  • Ayandeh Bank-Head Quarter
  • Oil Industry Investment Company-Head Quarter
  • Pars Khodro Building
  • Khalij-e Fars Complex
  • Pasargad Bank Complex Head Quarter
  • Negin Ofogh Niayesh
