Engineering, procurement, construction and finance (EPCF) of most parts of line 3 and 4 of Tehran subway was awarded as a Barter contract to Boland Payeh Co. and its financing partner. Line 3 of Tehran metro is the longest metro line in Middle East with 37 km in length.
BP has chosen New Austrian Tunneling Method (NATM) to construct lines 3 and 4 of metro, and was able to break the record of tunnel advancing of 60 m/day and track laying with 80 m/day, which are beyond what other companies have achieved in Iran. More than 1000 people have been contributing to construct this massive project and more than 87,000 tones reinforcement rebar, 630,000 m3 concrete and 445,000 m2 of formwork has been used and 2,150,000 m3 of earthwork has been done.
Lines 3 and 4 of metro will facilitate transport of 14 million residence of metropolitan Tehran, and help to reduce air pollution and traffic. According to Tehran Metro, using metro decreases travel time by 27 minutes per day, and more than $100 million on fuel per year.
As of August 2015, the progress of the project has been 92%. Passengers started using line 4 of metro in October 2012, southern and middle of line 3 of metro and airport path were completed in 2014.
