Petroserv is a wholly Qatari owned multi-disciplinary construction and engineering company that was established on 1st January 1978 by Sheikh Jassim Bin Mohamed Bin Jassim Al Thani. The Company started out life specializing in metals recycling. The then name for the Company was PETROSERV for Maintenance and General Services.

Over the intervening years, like with the majority of similar companies at the time, Petroserv ventured into a number of differing business lines as it sought to exploit potential opportunities that developed in Qatar. In 1990 the management of Petroserv saw opportunities developing in the petroleum industry and decided to establish an Engineering Division within the company. This division very quickly became the cornerstone of the business.

In 2003 it was decided to develop a Infrastructure Division within Petroserv. This was primarily due to the business opportunities that were surfacing in Qatar as the Qatari Government sought to develop its infrastructure. In addition, there are significant synergistic benefits between projects in this sector and that of the mechanical and engineering sector.

More recently, with the increasing levels of competition being experienced in Qatar and as the Qatar markets mature, it was decided that Petroserv develop to meet Qatar's construction demands. As a result it was decided that Petroserv is a multi disciplinary construction and engineering company with its Operational Divisions focusing on Infrastructure, Oil & Gas and Building developments. Accordingly, it either divested from or transferred out of all the non-core activities.
