Copperstone Mine. Tailing dam design and construction. Project manager and engineer in charge. Design and construction of a 50 acre tailings dam including embankment slope stability analysis and geotechnical sampling and testing. The dam is a HDPE geo-membrane double lined tailings storage facility with a sub-drain pipe network and a leak detection system. The project included a lined water recirculation pond (1 acre), construction oversight and approval of construction materials and field geotechnical testing

Arizona Department of Transportation, I-10/Central Ave. Freeway Tunnel. Project engineer. Construction of a mile long cut and cover tunnel freeway traffic. Duties included construction survey layout calculations for tunnel structure in reverse spiral geometry. Excavation mass balance analysis and tracking, tunnel falsework design assistance, and CPM schedule updates.

Greystone Mine. Tailing dam slope stability analysis.

Responsible in charge for the analysis of the slope stability of tailing dam (with Slope/w software) with 115 feet tall and 1300 feet long. The analysis was prepared for dam decommissioning and long term stability. Project also required a geotechnical drilling program including sampling and testing.

Mountain Springs Mine. Tailing dam slope stability analysis.

Responsible for the analysis of the slope stability of tailing dam (with Slope/w software). The stability analysis was for restart of operations of the dam. Site consists of industrial mineral mine with pit, dumps, concentration plant and tailing dam. Project also included, surface water studies and agency interactions.
