Our History

Ario's History

Ario obtained its first contract in 2010 as owner's engineer on the replacement of the SAFARI-1 nuclear reactor at Necsa. The extent of the scope of work on this project established our company niche - which is an ability to bridge the gap from technology and engineering to successful project delivery on complex projects. Since 2010, Ario has fulfilled the requirements of a number of new clients and has built up a track record in the nuclear, energy, defence, aerospace, management consulting and mining sectors.

Today, Ario manages a very well-diversified portfolio of projects with a common theme, namely that these projects are typically complex (usually high-tech), in the engineering field and often in regulated environments with a significant demand on SHEQ, formal processes and governance.

Our competitive edge is to an ability to serve our diverse customer base with a unique expertise, spawned from structured nuclear project management and engineering processes, but blended with a unique flexibility as required for different sectors and continuously changing local and global markets.
