Ep 3. New Orleans Surge Barrier

In season 4 episode 3 of Build It Bigger, viewers are taken to New Orleans to see the construction of a massive surge barrier system. The episode begins by presenting the devastating impact that Hurricane Katrina had on the city and the surrounding areas. As a result, there is a pressing need for better flood protection measures, and the surge barrier project aims to address this need.

The episode provides a detailed look at the design and construction of the surge barrier system, which consists of three large steel gates that can be closed in case of a storm surge. The first gate stands at 225 feet tall and weighs 700 tons, making it one of the largest moving structures in the world. The other two gates are slightly smaller, standing at 150 feet tall and weighing 500 tons each. All three gates are connected by a series of levees and floodwalls that run along the coast.

To create the surge barrier system, engineers faced a number of challenges related to the unique geography and environment of the area. For example, the system had to be able to withstand not only the powerful forces of a storm surge but also the corrosive effects of saltwater. Additionally, the system had to be designed to work with the existing infrastructure, including the nearby shipping channel and the city's existing flood protection system.

Throughout the episode, viewers are provided with fascinating insights into the construction process, including the use of massive cranes to lift the steel gates into place. The show also features interviews with project leaders and engineers who discuss the many technical and logistical challenges involved in building the surge barrier.

In addition to the surge barrier, the episode also highlights some of the other flood protection measures being implemented in New Orleans, including an improved pumping system that is designed to move water out of the city more quickly and efficiently.

Overall, season 4 episode 3 of Build It Bigger provides an informative and captivating look at the challenges and triumphs involved in creating one of the largest flood protection systems in the world. The episode offers a powerful reminder of the devastating impact of natural disasters and the importance of investing in infrastructure that can help protect communities and save lives in times of crisis.
