Engineering Design

Engineering Design that balances performance, efficiency and constructability.

Our engineers develop robust, cost-effective designs that balance technical excellence, constructability and whole-of-life performance.

What this service covers

Design and Analysis delivers engineering design solutions for new infrastructure and the modification of existing assets, helping owners maintain, upgrade, and expand their facilities with confidence. Our experience includes bridges, viaducts, wharves, industrial support structures, and other complex infrastructure. In addition to developing original designs, we are often engaged to review proposed schemes and identify alternative solutions that improve constructability, optimise material usage, reduce construction costs, and achieve project objectives.

Rail, MELConnX

Bayswater Viaduct, Morley to Ellenbrook Line

MELConnX asked D&A to develop an alternative to their existing design. Our modular scheme rotated the headstocks longitudinally and used a monopile solution that eliminated every pile cap on the project.

Result: Reduced material usage and lower construction cost on the 850m rail viaduct.
