AMEC, a project management and services company, said the contract covers engineering services that might be needed to assess, repair, or rehabilitate dams. It said services could apply to any of the district's 22 earthen flood-control dams.
The district foresees a need for field investigations such as borings, material sampling, and material testing. Additional technical services could include surveying, hydrology and hydraulics, geology, geomorphology, structural engineering, aerial mapping, biological sciences, archeology, landscape architecture, and public involvement.
AMEC said it considers the district's Saddleback Flood Retention Structure in western Maricopa County and Cave Buttes Dam east of Phoenix as the most likely candidates for its services.
AMEC previously worked on seven of the district's dams. The American Council of Engineering Companies presented the company an award for remediation at one of them, McMicken Dam.
