Tehran Berkeley have always endeavored to maintain its project planning in conjunction with the environmental control regulations. By observing this rule, we are trying to implement our studies and civil engineering activities in such a manner to meet the ever expanding requirements of the society together with betterment of the environmental control in the projects which are in hand throughout Iran.     Accordingly, and in view of Tehran Berkeley's various projects in the fields of: Oil and Gas (including Offshore Drilling, Design and Construction of Offshore Platforms, as well as the relevant onshore and offshore services), Civil Engineering (including Dam Construction, Water Distribution Facilities, Marine Construction and Airport Design). It was necessary to develop an environmental control department within our engineering group to study, control and enforce the required environmental rules and regulations in our various projects. Recent environmental studies includes: A : EIA for grand Bangestan oil storage development project (J.V. with Iwaco of Netherland) B: Environmental studies for strategic concrete oil tanks project (J.V. with Noroconsuit of Norway)- (Bushehr- Khuzestan) C : EIA for Karun 2 hydro electric project (1800 Mwe-2 billion m3 dam storage) D : Environmental studies for Charmahal and Bakhtiari province E : EIA for Noshahr port development (Caspian sea zone) F : EIA for Lali oil wells and facilities relocation on Gotvand dam storage.
