This begins with preliminary bridge layouts and scoping studies, carries through designing elements of the structure and construction support, and finishes with providing a load rating. Alliant offers structural engineering expertise across the full life cycle of pedestrian and vehicular bridge structures. This cycle begins with scoping studies and preliminary engineering, through final design and construction support, and on to widening and rehabilitation plans, and load rating. Alliant’s design experience extends beyond bridge design and includes a wide range of supplementary structures. And because all structures must be completed to exacting standards to ensure safety and longevity, our team carries out each project with the utmost attention to detail and quality throughout the process.
