A hands-on Mola model demonstration helped correct a common misconception in frame behaviour. When lateral load was applied to one column, the deflected shape revealed opposing curvatures—highlighting the importance of visualization in developing structural intuition. At Spannovation, we champion sketching and modelling to build the all-important engineering gut feel.

This article explores the intricate art and science of longitudinal tendon layout in segmental bridges—revealing how construction staging, geometry constraints, and pre-compensation forces shape design decisions. It highlights how tools like TendonWorks are revolutionizing the process through automation and AI-driven optimization, with case studies from the Mithi River and Yamuna Bridges demonstrating dramatic savings in time, cost, and complexity.

The closure pour is the final—and most critical—step in segmental bridge construction. It locks in alignment, internal forces, and long-term behaviors like creep and shrinkage. This article explores how timing, staged analysis, and the Pre-Compensation Force Method (PFM) can ensure structural balance, using real-world examples like the Yamuna and Mithi River Bridges. Closure isn’t just the last pour—it’s the final test.
