Our engineers played a key role on the design-build team for the federally funded rehabilitation of this historic 1,700-foot-long bridge—a combination concrete girder and steel truss movable structure spanning the Thea Foss Waterway and the BNSF mainline. The project involved extensive structural repairs, including the replacement of the truss bottom chord, gusset plates, steel stringers, […]
Engaged by ODOT, our team developed scopes of service for local bridge projects, delivering cost estimates, engineering data, and assessments of right-of-way and environmental impacts. Serving ODOT Regions 1 and 5, we provided precise documentation and adhered to ODOT’s General Expectations to ensure responsible, long-term value for public funds.
As Engineer of Record, our team oversees major wall structures and provides structural engineering for new street connections and upgrades along I-5 from I-405 to the Morrison Bridge, including the Broadway/Weidler Interchange. Scope includes seismic evaluations for nine bridges and Phase 1 seismic retrofits to enhance infrastructure resilience.
Provided structural engineering services for bridge deck replacement, expansion joint installation, and utility coordination on a historic bridge connecting Dallesport, WA, and The Dalles, OR. Project utilized Accelerated Bridge Construction (ABC) to minimize closures and impact.
Following flood damage near Elbe, Washington, our team assessed and designed the replacement of the Nisqually River Trestle on Tacoma Rail’s Mountain Division Line. We evaluated multiple bridge alternatives, selecting a two-span steel plate girder bridge for optimal performance, cost-efficiency, and environmental compliance, ensuring a resilient and sustainable rail connection.
Our team partnered with the City of Des Moines to restore the storm-damaged Redondo Boardwalk along Poverty Bay. Services included project management, structural engineering, environmental permitting, and construction oversight. Key repairs involved replacing girders, decking, and support elements, with FHWA funding accelerating timelines. The new design improves resilience, featuring concrete decking with wood-grain texture and UV-resistant coatings for longevity.
This 4-span 265’-0” pre-stressed concrete inverted tee girder bridge was constructed over the North Fork Big Nemaha River. Our team performed topographic survey, hydraulic survey, roadway design, bridge design, construction inspection and administration.
This 5 span, 180’-0” long bridge replacement project included a bridge over the Blue River on the south edge of Seward, Nebraska. This cast in-place concrete slab bridge was designed to handle the frequent flooding of the Blue River.
In this urban bridge project spanned the Blue River in Crete, NE. Our team performed the survey, design and construction inspection and administration of two bridges, storm sewer, concrete paving, environmental monitoring, seeding and erosion control.
Our team designed and provided construction management and construction inspections services for this federally funded project let by the NDOT. This project consisted of rehabilitating two bridges over Salt Creek in Lincoln, NE. The 2 bridges, one on 27th street and the other on West ‘O’ Street required several repairs.
