Skelly and Loy's Engineering Services Group functions within three primary engineering disciplines: mining, civil, and environmental engineering. The Mining Services Group is staffed with mining engineers (surface and underground), mineral processing engineers, and geologists who can guide mine development from initial exploration and feasibility evaluation through delivery of the mine product to the user. This group is recognized nationally and internationally for its experience and expertise. The Civil Services Group is staffed with civil, municipal, water resources, and construction engineers. Collectively, these employees bring numerous years of direct project and field experience to our projects. In the civil engineering arena, concentration is focused on site development, construction stakeout, water management and treatment, permitting, and municipal services. The Environmental Engineering Services Group is staffed with chemical, civil, water resources, and agricultural engineers as well as fluvial geomorphologists and environmental restoration specialists. These Skelly and Loy staff members have been credited with completing numerous award-winning projects recognized for innovation and environmental sensitivity. The Environmental Engineering Services Group specializes in waste handling, wastewater engineering, water supply, watershed assessments, hydrology/hydraulics, and natural stream restoration.
