Our History

Douglas OHI was established in Oman in 1981. Formed as a joint venture between British partners Interserve Group Limited and Oman Holdings International S.A.O.G. We’ve been carrying out construction projects in the Sultanate for nearly four decades now!

Since our founding we have undertaken a variety of civil and building projects, and in the last 20 years have ventured into oilfield activities throughout the country. We have faced many challenges along the way, but through these challenges we have developed our own proven safety and quality systems and ensured we are constantly improving..
