Bridges

Our Approach

D+A is passionate about the design of bridges.  Our engineers have extensive experience in employing the latest techniques in the analysis and design of bridge structures and have successfully completed a significant number of award winning projects in Europe, Africa and Australia.

Our concern includes the provision of services throughout all phases of the project live cycle from inception, feasibility studies, preliminary design, tender design, detailed design, construction phase support services and demolition or de-construction of bridge structures.

We appreciate that each project is unique in terms of constraints, objectives and stakeholder expectations.  D+A therefore follows a holistic approach to each project and employ technical and project managements skills appropriate to respond to the challenges faced on every project.  Over the years we have built up a significant knowledge base of specialised bridge construction techniques and the innovative application of construction materials to resolve project complexities.

We also appreciate the impact our work has on the communities we serve and follow a responsible design approach with a focus on improved safety, sustainability, reliability and reduced whole of life cost for each project.  Having worked with some of the world’s leading bridge architects, we have a thorough understanding of the creative process involved with the design of landmark bridge structures.
