Tehran Metro

Client:  Tehran Municipality

Engineer:  Tehran Metro company

Instruments:  Convergence meters 

Fully congested city with traffic, Tehran, was in long need for a fast underground transport system.  The operation of this started very long time ago but did not have a fast theme untill 1995.  Now the tunnels are completing one by one and lines are increasingly in production.  Diffewnt cobtractors were involved in construction of these tunnels among which the Khak-o-Sang company and Arsa company can be mentioned.  These companies separately bought convergence tapes from Payab Zamzam to control the quality of their construction works with them.
