FHWA Videos Recommend Best Hydraulic Field Scoping Procedures

By Dusty Robinson, PE, Senior Project Manager When it comes to designing roadways and other transportation infrastructure, the structures themselves aren’t all that needs to be considered. Hydraulic design – or the impact water has on this infrastructure – is a critical consideration in transportation design. For example, the most common cause of bridge failures… Read More »

Underwater Inspection: When, Why, and How

By Rick Maslyn, CBI Some of the most important foundation elements of a bridge are its least visible – the abutments, piers, piles, and footings submerged under the waterline. Regular inspection, both above and below the waterline, helps to keep aging structures solid and stable. About the Expert: Rick Maslyn, Ayres’ supervisor of structural inspection,… Read More »

Understanding Highway Hydraulics Keeps Bridges, People Safe

By Pete Haug, PE One of the principles of engineering is that water always wins. Whether contained in a river or falling in a rainstorm, water finds a way to infiltrate basements, saturate soils – and undermine bridges. The most common cause of bridge failures is from floods scouring bed material surrounding bridge foundations. What… Read More »
