Our History

Carrying the Legacy Forward

Our success story began in 1968, when Ewbank & Partners became one of Oman's first engineering practices, helping build the Sultanate's early infrastructure.

In 1999 the firm joined the Mott MacDonald Group as Mott MacDonald & Company LLC, gaining global reach and working on many of the country's landmark projects.

In 2024 the firm transitioned to Integrated Engineering & Technology LLC (IET), bringing nearly six decades of experience to a new focus on digital engineering, sustainability and integrated project delivery.

One Standard

Five Sectors,
One Way of Working

A desalination plant, a power grid line and substation, a sewer network, and an oil and gas facility look nothing alike. The discipline behind them is identical. The same rigour, the same accountability, and the same standard of delivery and execution is applied across every sector we serve.

That consistency is what lets a client trust us on a project type we have not built for them before. The sector changes. The way we engineer does not.

Specialised by sector. Unified by standard.

Built to Learn

Every project
teaches us something
We never stop learning

Wins, site visits, technical sessions, and digital tools are not separate stories. They are one practice compounding on itself. What our engineers learn on one project sharpens the next, and that momentum is how a firm nearly six decades old keeps moving forward.

It is also deliberate. Across our five sectors, every team runs 12 structured learning sessions a year, 60 in total, turning hard won project knowledge into shared capability the whole firm carries into the next mandate.

Knowledge is the one asset that compounds faster than concrete.

Learning & Development

Advancing Our People

Through continuous investment in talent development, knowledge transfer, and structured internal technical sessions across disciplines, our engineers stay current and capable of delivering at the highest level.

Modelled First

We resolve it
on screen
before it reaches site

Hydraulic models, BIM coordination, CFD and flood risk mapping are not deliverables we add at the end. They are where the design argument is actually settled, months before a contractor is appointed.

A clash caught in a model costs an afternoon. The same clash caught in the ground costs a programme, a claim, and a relationship.

The model is where the design is decided. Site is where it is confirmed.

Digital Solutions

BIM Modelling

Multidisciplinary coordination, clash detection, and digital handover to international BIM standards, from concept through construction and into operations.

Thrive

Long tenures are the norm. Most of our senior team grew up inside the firm.

Who We Hire

We do not hire
for a vacancy
We hire for a career

A CV tells us what someone has already done. It says very little about what they will build over the next ten years. We hire engineers we expect to still be here when the projects they are starting now are finished.

That is why the first year matters more than the first month. New engineers sit on live deliverables, in front of clients, and on site. The learning curve is steep on purpose.

Hire deliberately. Invest early. Keep people long.
