For over 50 years, we have worked alongside our clients to deliver outstanding and award-winning bridge infrastructure across New Zealand, Australia and the Pacific.

Our experienced engineers and construction specialists are receptive to delivering the solutions clients need, connecting communities and transforming how people access the places they live, work and play. We achieve this using our technical excellence and continually striving to innovate - from initial concept design and modelling, to operation and maintenance throughout the structure's full life-cycle.

With a large bridge engineering team across Australasia, we are able to work in partnership with clients and contractors to deliver design, assessment, strengthening, asset management and construction phase services for road, rail and pedestrian bridges of all forms and functions, while also rising to the challenge of sustainability. We have extensive experience in complex bridges for major projects including structural forms such as pre-stressed precast concrete and balanced cantilever bridges, steel bridges, arch bridges, truss bridges and cable-supported bridges.
