With weather-related disasters on the rise and the increasing risks posed by aging infrastructure, the U.S. Army Corps of Engineers (USACE) continues to invest in projects that ensure more resilient structures—among them, rehabilitation of the Herbert Hoover Dike (HHD) in Florida.

The dike’s network, including earthen dam, hurricane gates, and water control structures, is critical to protecting the Kissimmee-Okeechobee-Everglades ecosystem, preserving its water quality, and shielding residents from the risk of flooding during high water events.

Since 2018, AECOM has supported USACE Jacksonville’s HHD rehabilitation efforts by monitoring construction progress along its 143-mile perimeter, including more than 55 miles of cutoff walls, 48 culvert replacements and alterations, embankment raising structures, and other improvements. We monitor progress against scheduled outcomes to ensure early detection of potential issues. We also document inspections of work areas, provide enforcement of health and safety polices and regulations, and conduct periodic reviews of contractor quality and safety management plans.

In 2020, the coronavirus pandemic impacted the project in unique and challenging ways—including some site closures—but ultimately our team adapted to remain steadfast in providing continuous monitoring and quality assurance services throughout the crisis.
