Engineering services built on over 20 years of founders’ experience in delivering onshore and offshore detailed design and other engineering services for the oil & gas, infrastructure, and industrial sectors for the energy sector.

Our experience spans major clients across the region, including Saudi Aramco, ADNOC, and OQ, as well as projects throughout the MENA region.

AUSAUS delivers integrated engineering solutions across pipeline engineering, process and piping, mechanical, civil & structural, electrical, and instrumentation disciplines—supported by advanced 3D modeling, CAD, and BIM capabilities.

Positioned as a specialized Detailed Engineering House, AUSAUS bridges the gap between FEED and construction, providing end-to-end detailed design services from IFC deliverables to shop drawings, as-built documentation, and full support during pre/commissioning phases.
