Washington's scour mitigation needs span Puget Sound's tidal and seismic exposure and the Cascade Range's snowmelt-driven river flow, and WSDOT infrastructure across these varied settings requires scour protection calibrated to whichever flow regime and seismic hazard level a given site presents.
This pattern is consistent with the broader Washouts & Scour Damage challenges GSI addresses across the state.
Riprap and armor stone for Washington's Puget Sound infrastructure are sized for tidal flow patterns distinct from the Cascade Range's snowmelt-driven river dynamics. GSI's bridge solutions capability supports this step.
Grout-filled mattress systems for Washington bridge crossings account for the state's Cascadia subduction zone seismic exposure alongside standard scour protection. This is one application of GSI's broader emergency bridge repair expertise.
Sheet pile and grouted rock protection at Washington bridge foundations addresses both tidal and snowmelt-driven scour depending on site location. GSI's coastal and bluff stabilization experience informs this approach.
This approach is informed by GSI's broader water infrastructure work across Washington.
Engineered for Washington's conditions. GSI's Washington scour mitigation adapts to the state's dual exposure — Puget Sound tidal dynamics and Cascade Range snowmelt flow — within one DOT's jurisdiction. It's backed by GSI's broader transportation infrastructure and engineers capability.
Design/build delivery. One team designs and builds — avoiding the miscommunication between separate design and build firms.
WSDOT specification compliance. Engineering records and field methods satisfy state DOT requirements beginning with the first engineering package.
