Juan E. Quiroz
Groundbreaking analysis saves millions on Panama Canal project
38, Lead Structural Engineer, Energy & Industry Operations

Among other achievements, engineer Juan E. Quiroz led the team that produced design and construction drawings for the third set of lock structures included in the Panama Canal Expansion Project. To do so, he and fellow team members generated 2D and 3D finite element models to account for a fault zone and the project's geologically diverse setting. Innovative soil-structure interaction analysis reduced stresses in the structure by 20%, reducing project costs by millions of dollars. As a recognized leader in advanced analysis, Quiroz frequently is recruited to perform quality and technical reviews for complex structures, including dams, powerhouses, tunnels and spillways. He serves as an adjunct professor at Chicago's Illinois Institute of Technology, where his emphasis on the "big picture" and overall structure is intended to prevent hazards.
