* "Employee," for purposes of CalGeo membership dues calculations, is defined as any person directly involved in soil engineering, geology, or environmental sciences; support staff (lab and field technicians) and administrative staff involved in supporting these services in the State of California. Part-time employees should be on a full-time equivalent basis (total part-time-employee hours divided by 160 hours).

*Multi-disciplinary or multi-state/national firms need only count the employees in the geotechnical group within California.
