Hexa has been involved in design and supervision of urban railways since 1986 through the contract of three underground stations of Tehran underground metro. Afterwards, Hexa has extensively been involved in urban railway projects of Iran’s major cities such as; Mashhad, Tabriz, Shiraz, Esfahan and Karaj providing consultancy services. In this regard, Hexa has come up with the best solutions in terms of economical design and practical construction methods for shallow box tunnels and stations using both precast and cast-in-situ elements by Cut & Cover and Top-Down methods aiming to reduce civil work costs of projects. Hexa has been encouraged and granted by clients of urban railways by reducing cost of projects for dozens of kilometers of shallow urban box structures comparing to other methods such as mechanized and NATM methods.
Urban railways have mostly been regarded and interpreted as underground and metro systems in Iran but quite recently the concept of monorail are being introduced to urban transportation of the major cities. In this regard, Hexa has recently become responsible for design and supervision of Qom monorail project as an alternative solution in urban transportation.
In rather more complete contracts of urban railway projects these days; Hexa constantly shapes consultancy consortiums in order to carry out basic and detailed design along with architectural, electrical and mechanical issues involved. Several architectural and E&M international and local firms could be mentioned in list of Hexa MOUs and agreements.
Considering the increasing demand of underground passages particularly urban railways in large and populated cities, the horizon of Hexa Consulting Engineers in investigation, design, supervision and management of large urban railway projects is significantly expanding.
