Part of the message of the CEO of Behro Consulting Engineers Company on the occasion of holding an international exhibition of tunnel equipment and underground metro spaces Rolling stock and electrical and mechanical equipment of metro lines and stations, include more than 50% of cost of construction and operation of metro lines. With intensification of sanctions and increase in exchange rate, there is a great opportunity for growth of capabilities of domestic industry in production of metro construction equipment and machinery in the country . In recent years, despite the sanctions, more attention has been paid to manufacturing of equipment based on domestic capabilities and in the future, we will not need a significant amount of imports of metro equipment and facilities. In addition to creating jobs, knowledge and technology have grown significantly in this field, and such opportunities are needed for development in metro equipment and facilities sector. in order to share the sense of social responsibility and in order to share knowledge, present professional and specialized experiences and achievements, introduce capabilities, inform specialists and interested parties in related fields, Behro Consulting Engineers Company has decided to be more active in scientific fields and social activities to play a role in this field more than before. Therefore, Behro has actively participated in holding the international exhibition of tunnel equipment and underground metro spaces (IRANMETOEX 2022) and this event, which is held for the first time in Iran by Banyan Farda Roshan Company, is a great opportunity for all those involved in field of metro equipment and facilities and underground spaces. Behro Consulting Engineers Company, with its experience and history as old as the country's metro, has always accompanied its employers in order to empower domestic equipment manufacturers and has encouraged and supported the growth of domestic knowledge in this field. The support of present exhibition is also one of these groundbreaking measures in the field of evolution of the country's metro industry, which we hope will be useful and effective so that a more effective step can be taken for the well-being of the dear people of our country.
