About us
Engineering solutions that connect people, places and possibilities.
For decades, we have shaped the built environment through collaborative engineering, bringing together people, ideas and expertise.
What began in a shared Sydney office in 1958 with three entrepreneurial engineers, Dick Taylor, Jock Thomson and Alan Whitting, has grown into an international, privately owned engineering consultancy delivering some of the world’s most complex projects. While our business has grown, one thing has remained constant. Our belief that great engineering starts with people.
TTW established its first Jakarta office in 1993, one of the earliest steps in our expansion into Southeast Asia. From our first office at Plaza Blok M in South Jakarta, the practice quickly took root in one of the city’s most dynamic built environments.
Over the years, the team in Jakarta has grown steadily and today is home to more than 80 engineers, designers and specialists, reflecting both the scale of Indonesia’s infrastructure ambitions and the depth of trust our clients place in us.
Marten Eddy has led the Jakarta office as Executive Director since 2006, providing the continuity of leadership and local knowledge that long-term client relationships are built on.
Our Heritage
Engineering with people at the heart
We challenge convention through thoughtful engineering and intelligent innovation. Advanced technology, evolving materials and practical construction insight allow us to solve complex problems with clarity and creativity. Technology expands what is possible. It is the insight, curiosity and collaboration of our people that turn possibility into built outcomes, and sets us apart.
Local expertise. Global Reach.
With six offices across Australia and Southeast Asia, we offer local teams with local expertise whilst maintaining global reach. Our footprint supports our commitment to delivering practical solutions wherever our clients need us.
