AESI provided facility location services and GIS system development for 650 assets including valves, hydrants, and other appurtenances for the Site 1 Facility. Approximately 650 assets including hydrants, valves, sewer manholes, water valves, electrical equipment, and miscellaneous features were located using differential GPS equipment. Asset mapping was developed using the field GPS observations, as-built drawings, and Boeing staff coordination. The final product was a web based GIS/Facility Management System.
