Classification Specification

BRIEF DESCRIPTION OF CLASS SERIES

This series requires specialized training and experience to operate drilling equipment used for acquiring samples of rock, soil, and pavement and measuring ground water as part of subsurface explorations for geotechnical engineering purposes. These positions are classified only in the Geotechnical Engineering Bureau in Albany and the Regional Offices of the Department of Transportation.

DISTINGUISHING CHARACTERISTICS

ASSISTANT DRILL RIG OPERATOR: non-competitive jurisdictional class; entry level; appointment requires completion of a two-year traineeship or comparable experience; assists the Drill Rig Operator in field operations of the regional drill crew; responsible for the drill crew in the absence of the Drill Rig Operator; generally classified only in Regional Offices.

DRILL RIG OPERATOR: non-competitive jurisdictional class; first supervisory level; supervises and trains the Assistant Drill Rig Operators, Trainees and Laborers assigned to the Regional Drill Crew; responsible for field drilling operations and records.

DRILL SUPERVISOR: assigned to the Geotechnical Engineering Bureau in Albany; travels Statewide; assists the Supervisor Drilling Operations in managing the drilling program.

SUPERVISOR DRILLING OPERATIONS: one-position class; assigned to the Geotechnical Engineering Bureau in Albany; has overall responsibility for Statewide drilling operations, including both State and contractor drill crews.

RELATED CLASSES

Core Drill Operators operate core drill apparatus to take samples of finished concrete or bituminous pavement or cores from a concrete structure, label cores with appropriate markings, ship the samples to the Regional Office, maintain work activity reports, and maintain the drilling equipment.
