What happens when your project site is in a floodway AND a seismic zone at the same time?
You don't get to design for one hazard and hope the other stays quiet. You engineer for both — every possible load, every possible sequence.
On this project, that meant accounting for:
• Hydrostatic and hydrodynamic pressure from floodwaters
• Debris impact forces carried by moving water
• Uplift and buoyancy acting on submerged foundation elements
• Seismic lateral demands from ground motion
• Scour, erosion, and saturated soil pressure on foundations
Then we modeled five combined load scenarios — flood only, seismic only, flood + seismic simultaneously, flood then seismic sequentially, and seismic then flood sequentially — to validate structural performance under every foreseeable condition.
The result: an elevated, ductile structure with deep driven piles, corrosion-resistant materials, scour protection, and a continuous seismic load path — resilience confirmed through advanced structural analysis.
