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, the $1.5-billion 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.
Starting in 2018, AECOM supported USACE Jacksonville’s HHD rehabilitation efforts by providing construction management and multidisciplinary quality assurance services. The project involved work along the dike’s 143-mile perimeter, including 56 miles of cutoff walls, 28 culvert replacements and alterations, embankment-raising structures, and other improvements. We monitored progress against scheduled outcomes to ensure early detection of potential issues. We also documented inspections of work areas, provided enforcement of health and safety polices and regulations, and conducted 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.
With the team’s dedication and innovative practices, we were able to complete the project three years ahead of schedule, in January 2023. After supervising 1,040 days of active construction, our team surpassed expectations, achieving an outstanding safety record and exceeding minority and small business participation goals.
