Category 1: New Buildings under $30 Million | Outstanding Project
m.o.r.e. Cabin – La Pêche, Québec, Canada | Dan Bonardi Consulting Engineers Inc.
The m.o.r.e. Cabin is a 900-square-foot private retreat on a hill overlooking Lac du Brochet, Québec. The building touches the site at only two points: a small concrete storage building supports the cabin at the top of the hill, and a steel mast supports the opposite end. The cabin cantilevers 25 feet beyond the mast. The structure consists primarily of glulam members and cross-laminated timber panels (CLT). Wood was chosen because of its sustainable qualities. Prefabricated glulam and CLT components reduced installation time, and the natural beauty of the wood panels eliminated the need for wall and ceiling finishes.
Category 2: New Buildings $30 Million to $80 Million | Outstanding Project
Idaho Central Credit Union Arena – Moscow, ID | StructureCraft
The Idaho Central Credit Union Arena models the use of timber in long-span sports facilities in North America. Inspired by the undulating landscape forms of the Palouse region, the 4,000-seat multi-use facility was designed as a dramatic gateway to the University of Idaho campus. The dominant feature of the structure is the majestic timber roof, a doubly curved plywood diaphragm supported by 150-foot hybrid timber/steel trusses, all carefully proportioned for both aesthetics and structural efficiency. A parametric model was created using genetic algorithms to perform structural optimization on the trusses.
Category 3: New Buildings $80 Million to $200 Million | Outstanding Project

I-74 over the Mississippi River – Quad Cities, IL and IA | Alfred Benesch & Company
Spanning the Mississippi River between Iowa and Illinois, the $1.2B reconstruction of I-74 is an engineering marvel that will benefit the region for decades. The signature elements are a pair of basket-handle, true arch bridges with an 800-foot navigation span. The eastbound structure also supports a multi-use path, cantilevered outside of the rib, allowing pedestrians and bicyclists to cross the Mississippi River while taking in the wonderful views. Several ingenuities were implemented, including long, unbraced ribs with Vierendeel bracing, innovative stainless steel rods at the arch anchorage, and a hybrid foundation to transfer the massive thrust loads to bedrock.
Category 6: Forensic/Renovation/Retrofit/Rehabilitation Structures under $20 Million | Outstanding Project
Fox Plaza Tower Seismic Upgrade – San Francisco, CA | Saiful Bouquet Structural Engineers, Inc.
Fox Plaza Tower is a 30-story steel building with an unconventional lateral system consisting of steel moment frames. These frames have haunched beams with Pre-Northridge welded moment connections to both strong and weak axis of built-up columns in a space-frame configuration. The connections’ unique characteristics necessitated full-scale laboratory testing and extensive nonlinear response history analysis to assess the building’s seismic performance. The seismic retrofit scheme was specifically tailored to address concerns with excessive building drift and the potential for building collapse, including direct connection strengthening at the upper levels and exterior braced frames with fluid-viscous dampers at the lower levels.
Category 7: Forensic/Renovation/Retrofit/Rehabilitation Structures over $20 Million | Outstanding Project
Climate Pledge Arena – Seattle, WA | Thornton Tomasetti
Seattle’s historic KeyArena has been transformed into a new home for the NHL’s Seattle Kraken. The $930-million renovation is now Climate Pledge Arena. To preserve the landmarked, 44-million-pound roof structure and exterior curtain wall, it was necessary to temporarily support the roof and build the new arena underneath. Additional challenges include high seismicity, an aggressive schedule, and a commitment to making it the first net-zero-certified arena in the world. The project team worked together to address these challenges and transform a historic venue into a first-class sports and event facility, which opened in time for the 2021-2022 NHL season.
Category 8: Other Structures | Outstanding Project
SFU Stadium – Burnaby, BC, Canada | Fast + Epp
The new 1,800-seat stadium at Simon Fraser University is home to the SFU Athletics Team and a new facility for community and student events. The crowning piece of the design is a striking CLT canopy that cantilevers 52.5 feet, providing weather protection and unobstructed views for the spectators below. Early in the design process, the design team had the idea of hanging CLT panels below cantilever steel girders, providing a ‘wow’ statement of continuous wood structure. Supported by steel girders, the canopy required careful structural detailing to ensure the exposed structure was seamlessly coordinated with the design team’s vision.
