  1. Head Tapeman-responsible for the accuracy and speed of all linear measurements with the tape.

  2. Recorder-keeps record of all measurements, sketches and observations during the process of measurement.

  3. Flagman- his duty is to hold the range pole (or flagpole) at selected points.

4. Rear Tapeman-his duty is to assist the head tapeman during taping operations.
