Risk Management: The John James Audubon Bridge Project: Engineering/Construction Methods, Risk Managment Challenges

Pdf Summary

IMUA, founded in 1947 in Colorado, is a company with around 2,000 employees engaged in constructing transportation, water, and energy infrastructure in the US and Canada. They focus on inland bridge construction with projects like the I-35W in Minnesota and the Glenwood Canyon Corridor in Colorado. One notable project is the John James Audubon Bridge featuring a cable-stayed unit. The project, led by various contractors, had contract details finalized in 2011 with a total value exceeding $355 million. The construction faced challenges such as finding adequate foundations and dealing with the Mississippi River's variability. Techniques like using a modular cofferdam for pier construction were employed. The project marked the first design-build endeavor for Louisiana DOTD and set records for cable-stayed bridge length in the Western Hemisphere. The construction involved complex processes like jack control for lowering the structure and installing the concrete seal. With extensive planning, teamwork, and innovative solutions, IMUA successfully navigated the obstacles in this significant bridge construction project.
