International Partnering Institute Recognizes Five North American Flatiron Projects

The International Partnering Institute recognizes four North American Flatiron projects for their excellence in construction and collaboration. One additional project received an honorable mention. These awards underscore Flatiron’s commitment to innovative practices and exceptional outcomes.  

Award-Winning Projects 

The Route 210 Roadway Rehabilitation and Lane Replacements Project — Wheatland earned an Honorable Mention 


Project Highlights 

The Bow River Twinning Bridge, located in Calgary, Alberta, used a cast-in-place segmental cantilever method that is rarely used in North America. The scope of work consisted of the construction of the 470 meter or mile?, five-lane southbound bridge, a 50m single-lane collector road bridge over Scenic Acres Link Drive, a south bank stabilization retaining wall, a dry pond and drainage improvements, and the widening of 2.5 kilometers of shoulder and collector road along Stoney Trail. The Bow River Bridge Twinning project was a key component in the completion of the Calgary Ring Road and provides vital transportation infrastructure for growing communities in the Calgary metropolitan region. 

The Maloney Pumping Plant and Sobrante Water Treatment Plant Improvements project met growing demands while maintaining high water quality standards in California’s Bay Area. The project increased water treatment capacity, optimized energy usage and enhanced overall operational performance.  

Route 805 Sweetwater River Bridge, located in the South Bay area of San Diego, underwent widening and safety enhancements. These improvements included the construction of sound walls and upgraded roadway features to enhance traffic flow, safety and overall infrastructure resilience in the region. 

The San Gabriel River Bridge Hinge and Diaphragm Repairs project near Los Angeles required two 126-hour freeway closures, the first for Los Angeles County and the second ever for Caltrans. But the hard work paid off — the 250-meter-long structure reached completion 16 days ahead of schedule. 

Route 210 Roadway Rehabilitation and Lane Replacements project – Wheatland, also in Los Angeles, centered on the comprehensive revitalization and modernization of the roadway infrastructure. The $150 million endeavor involved replacing 52-lane miles of pavement, 300,000+ cubic yards of roadway excavation and upgrading 16 bridges with approach slabs and concrete barriers. 

Every year, the International Partnering Institute recognizes projects and individuals who best exemplify the principles of partnering and promote their mission — to transform the construction industry and achieve exceptional results through a culture of collaboration. The awards celebrate success, share lessons learned and best practices, and acknowledge teams and individuals who achieve extraordinary results.
