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

Our experienced bridge engineers and bridge construction specialists are receptive to delivering the solutions clients need, enhancing community connection and transforming how people access the places they live, work and play.
 
We achieve this through our technical excellence in bridge design and continually striving to innovate – from initial concept and modelling, to all stages of the construction process, to operation and maintenance throughout the full design life of the bridge structure.

With a large bridge engineering team across Australia, New Zealand and the rest of the world, we are the partner of choice for delivering design, assessment, strengthening, asset management and construction phase services for vehicle, rail and pedestrian bridge structures of all kinds, while also rising to the challenges of sustainability, security and road traffic safety.

Experts in Bridge Design and Construction Management


Our bridge designers and engineers specialise in tackling complex challenges such as deep water foundations, managing dead loads and live loads from moving vehicles, handling horizontal forces, and balancing tensile forces and compression through carefully designed upper and lower chords.

We have extensive experience in complex bridge designs for major transport infrastructure projects, including:

  • Pre-stressed precast concrete bridges
  • Balanced cantilever bridges
  • Steel bridges
  • Arch bridges
  • Truss bridges
  • Suspension bridges
  • Cable-stayed bridges


We can also deliver customised, compliant solutions for individual elements like bridge decks, abutments, piers, trusses and guardrails.

Our other services include:

  • Bridge inspection
  • Strengthening and assessment of existing bridge structures
  • Pre-stressing of construction materials
  • Asset management for major bridges
  • Construction phase support including review, testing and commissioning
  • Specialist advice for road, rail and pedestrian bridge projects

Talk to us about

Sustainability

Consultation with stakeholders and partners is an essential factor in the design of bridges to achieve sustainable outcomes that make everyday better for the communities we serve. Using our experience in carbon assessments and climate and disaster resilience, we can help future-proof transport infrastructure at risk from climate change across Australasia and the Pacific.

Bridge design services

With a large bridge engineering team across Australasia, we have the resources to help bring your bridge project to life. Our experience ranges from single-span crossings through to multi-span rail, road, foot bridges and viaducts to large river and harbour crossings.

Construction phase support

Our experienced engineers and construction specialists can support you through the construction phase of your projects, giving you confidence in the design and construction of your assets. From on-site construction monitoring to review conformance, through to Shop drawing reviews, design change requests, and Producer Statements (and more) provided by our Chartered Engineers.

Asset management

We understand that your existing structures represent the investment of previous generations. Supported with the latest technologies, we offer a highly-skilled team who are passionate about sustainably managing assets through inspections, timely refurbishment, strengthening and full or partial asset replacements.
