When catastrophic flooding wiped out a critical bridge in Adams County, Colorado, the county faced an urgent challenge: restore safe, reliable access for nearly 1,000 daily vehicles—farmers, freight haulers, and residents. The traditional construction approach would take 18 months; the community couldn’t wait.
This session reveals how the county, its engineers, and contractors completed a permanent, resilient bridge in just five months using lean construction principles, prefabrication, and collaborative CM/GC delivery. Attendees will learn how the project team evaluated five replacement options, ultimately selecting an innovative prefabricated modular bridge system with pre-engineered abutments, wingwalls, and superstructure. This reduced estimating complexity and enabled a cast-in-place installation in only 450 man-hours—an 80% reduction from typical methods.
The presentation will cover:
- How lean planning and early contractor involvement eliminated downtime and delays.
- Resource allocation tools that optimized scheduling and crew efficiency.
- Prefabrication techniques that cut on-site work while maintaining quality.
- Material innovations, including ASTM A1094 corrosion-resistant rebar, that enhance lifecycle value.
The session will feature both the bridge system manufacturer and the contractor’s perspective, offering a complete view of decision-making, cost control, and execution. Interactive elements—live Q&A throughout, and real-time polling—will ensure participants actively engage with the concepts and connect them to their own projects.
By the end, attendees will have a clear roadmap for integrating prefab and lean practices into their preconstruction and estimating processes, empowering them to deliver faster, more cost-effective, and more resilient projects.
