· Line Plan Plotting · Field Orientation · Prepare Equipment |
- Geodetic engineer complete data from client, including line coordinate, base map and reference point.
- Geodetic engineer prepare the instruments survey, plan the blocking and polygon/traverse design.
- Geodetic engineer ensure that data was suitable with azimuth, coordinate control and deviation. If data not suitable, the process back to line survey (revision).
- Geodetic engineer conduct data processing.
- Senior surveyor process data from field and make previous program of line survey.
- Senior surveyor help geodetic engineer, and conduct the polygon design, blocking and loop accuracy.
- Field surveyor performs line survey with stakeout method. Field surveyor ensures accuracy, numbering and recording of data.
- Subcontractor conducts line clearing and bridging. Field surveyor ensures that clearing comply with specification. Geodetic engineer or Senior- surveyor ensures that clearing and bridging comply with specification.
4.2 RECORDS
Records resulting from this procedure are identified in the flow chart. The retention and archive periods for records is defined in FM.IMS.004 (Document Retention & Archive Periods).
