Repeat Business

As award-winning consulting engineers, for over 60 years we’ve partnered with architects, developers, builders and project managers to tackle the most complex projects and engineer their vision.


A privately owned Australian company, our strong reputation exists due to our proven ability to produce innovative, economical and elegant designs in the public and private sector. We offer the benefits of scale with respective disciplines successfully delivering significant projects through structural, civil, traffic and façade engineering services.


Focusing foremost on the client’s goal, our design approach is customised for every project. Our solutions are enhanced by our dedicated and integrated teams' approach and the use of advanced engineering techniques for modern materials.


ONE TTW is our ethos, which encapsulates all the experienced, smart and creative people that make us who we are. We value; integrity, teamwork, innovation, communication, sustainability, and our community.


We are on a journey, embedding sustainability across all decisions made in both our designs and the wider business day to day operations. With the ever increasing threat of climate change, our teams are looking to new and innovative ways of designing buildings, infrastructure and precincts. 

Through our expertise and in-house sustainability lead, our designs are aimed to incorporate recycled and reused materials, water reuse, improved water quality treatment and structural forms that enhance the environmental performance of developments.  

Our teams pride themselves in promoting research in sustainable initiatives that can be realised in practice. We continually investigate ways of reducing our ecological footprint through reducing resource consumption and applying innovative recycling initiatives, so we are always working towards a more sustainable future.

In support of the global communities need to address carbon emissions, we are on a path to progressively decarbonise our structures over the next few critical decades. This is a big challenge, but one we are up for in our continual pursuit to be market leaders and to provide a premium service to our clients and design partners.

In 2022, we aim to measure the embodied CO2e emissions in all of our current structural projects in Revit through our Carbon Calculator, developed in-house for our needs.

Integrated Approach

Our clients continue to bring us projects with an ever-increasing range of complexities and needs. Our integrated teams approach means we bring our specialist structural, civil, traffic and façade services to the table with the value add of teams across our business delivering digital and construction engineering, heritage and physical security expertise, low carbon design and the ability to address future climate risks.

Additional internal research and development expertise means we optimise every opportunity to deliver significant projects. Our large, technically skilled resource base will guarantee you the certainty of delivery across the lifecycle of the project. Together, our teams are creating solutions that brings the architectural vision to life.
