DESCRIPTION

The government authority in Maricopa, Arizona, seeks geotechnical engineering services supporting land subsidence and earth fissure monitoring, geotechnical field investigations, material sampling and testing, engineering analysis, instrumentation installation, and the planning and design of corrective actions. Services may address potential dam safety issues and support dam rehabilitation or replacement projects.

The work may include collecting, organizing, and reviewing existing project records; investigating dams, levees, dikes, spillways, and related features through test pits, borings, material sampling, and laboratory testing; conducting technical studies and engineering analyses; and performing site-specific repairs. The selected provider will also evaluate conventional survey results, including vertical leveling and GPS-based positioning of selected monuments.

Laboratory and field testing may involve soil properties such as plasticity, gradation, shear strength, bulk density, and consolidation, as well as construction materials including Portland cement concrete, asphalt concrete, reinforcing and structural steel, soils, wood, masonry, prefabricated construction components, concrete pipe, and asbestos cement pipe.
