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 served as Engineer of Record for LA Metro’s Westside Purple Line Extension, designing Century City/Constellation Station and reviewing plans for Wilshire/Rodeo Station. The project demanded advanced soil-structure interaction, 3D modeling, and excavation support to ensure stability beneath densely developed areas along Wilshire Boulevard, factoring in seismic resilience and loading impacts from nearby high-rise buildings in this urban infrastructure initiative.
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.
The transformation of San Antonio’s historic Mission Road Power Plant into EPIcenter marks a shift from an industrial site to an energy innovation hub. Utilizing advanced laser scanning and drone technology, over 1,000 scans were captured to create a detailed Revit model. This model helped facilitate design, planning, and marketing efforts, blending historic preservation with cutting-edge technology for the future of energy.
To prepare for a projection mapping show at the New York Public Library, a 3D scan of a historic space was conducted using a Faro S series scanner. Eight high-resolution scans captured 350 million points in under two hours, creating an immersive 3D point cloud. The mesh was refined collaboratively, enabling content development ahead of the event.
A hillside property with multiple levels, including a World War II-era bunker, was meticulously scanned to capture every detail for restoration. The owner, an architect, sought a comprehensive understanding of the unique estate before making improvements. After a three-day scan, a highly detailed Revit model was created, preserving the property’s intricate features and history.
