FLATIRON-AECON JOINT VENTURE

Flatiron-AECOM Joint Venture specializes in heavy civil engineering construction, with demonstrated expertise in complex water infrastructure projects requiring precise engineering coordination and environmental compliance. Their core capabilities include the design and construction of fish passage facilities, dam modifications, and hydraulic structures that support ecosystem restoration while maintaining flood control and water storage functions. The team applies advanced geotechnical, hydrologic, and structural analysis techniques to deliver mission-critical infrastructure in sensitive ecological zones, often under stringent regulatory oversight. Their technical proficiency spans concrete placement in high-water environments, sediment management, aquatic habitat mitigation, and integrated permitting strategies for federally regulated waterways, positioning them as a specialized contractor for high-stakes civil works requiring interdisciplinary coordination. The contractor has delivered work for the Department of Defense, specifically on projects involving water resource infrastructure tied to military land or defense-related water systems. This engagement reflects a focused relationship with DoD’s civil works and environmental restoration initiatives, particularly where dam safety, aquatic connectivity, and compliance with the Endangered Species Act intersect with operational readiness. Their primary industry focus is in NAICS 237990 — Other Heavy and Civil Engineering Construction — which encompasses large-scale, non-building infrastructure such as dams, spillways, diversion channels, and fish ladders. They operate at the intersection of hydraulic engineering and environmental compliance, serving markets where public safety, ecological restoration, and federal regulatory frameworks converge. This niche specialization distinguishes them from general contractors by emphasizing technical rigor in water resource infrastructure. Flatiron-AECOM Joint Venture is structured as a 2K entity, operating from Renton, Washington. While no government certifications are currently listed, their project execution demonstrates alignment with federal construction standards and environmental compliance protocols. Their geographic positioning in the Pacific Northwest supports proximity to major federal water infrastructure assets, enabling responsive mobilization for complex, site-specific civil works across the region.
