A bridge is a structure built to span physical obstacles (e.g. body of water, valley, roads, soft ground) without closing the way underneath. Bridge design requires developing a very good understanding of the physical constraints including topography, geology, other infrastructure, and foundation conditions. It is critical that a comprehensive investigation program is carried out so that a suitable founding stratum can be identified, and geotechnical design parameters established that will result in a safe and economical footing design. A minimum of one investigation point per pier or abutment is recommended in combination with geophysical profiling to define the geological model.
Asset’s Engineers have experience completing investigations for a wide range of foundation conditions applicable to bridge design, including over-water investigations, soft soils, complex alluvial deposits, and soft and hard rock. We are experienced in the Ultimate Limit State bridge design standards for foundations.
