In 2019, the Louis Armstrong New Orleans International Airport had to push back its plans to open its new $1.3 billion airport terminal building from February to May. It was the third time that the opening—originally scheduled for May 2018—had been delayed. Latest reason: Inspectors found 126 ruptures in the brand-new, never-used sewer lines that ran beneath the terminal building.

If you’ve ever been to New Orleans, you know that it’s a low-lying, swampy kind of place. That’s because almost all of the city is at or below sea level. For this reason, the airport’s building engineers expected anything set into the soil would sink, or “subside,” as it’s called in the industry, as the soil compressed. The terminal building sat atop hundreds of giant pilings that had been driven deep into the ground, so it was not going to subside. But the sewer pipes laid in the dirt beneath the foundation might, if nothing were done to prevent it. So they did something: The pipes were secured to the foundation using steel straps called “hangers.” Only problem: instead of attaching the $6 hangers every two feet along the pipe as the building inspector, James Mohamad, had advised, the building contractor got approval to save $22,000 in materials, plus the installation cost, by installing the hangers every three feet. That may not sound like much of a difference, but it was enough to cause the sewer pipes to rupture in 126 places as soon as the soil began to subside.
