NRS-21473 | Department of Main Roads Control Marks

Full description

Roads and Maritime Services regularly commissioned surveyors to survey the resumption of existing roads or future road sites prior to undertaking road works across the state as part of its Survey Property Function. The majority of the Licensed and Registered Surveyors commissioned for this activity were full-time employed by DMR as part of the Survey Property division; however, DMR did routinely contract Licensed and Registered Surveyors to undertake select pieces of work.

Control Marks are the primary/base control used for preliminary survey measurements; it may consist of any known point capable of establishing accurate control of distance and direction.

Department of Main Roads Control Mark sketch plans hold the following information; parish; municipality or shire; road number; type of mark; reason the mark was placed; co-ordinate values of mark; and level of mark. Department of Main Roads had its own control network similar to SCIMS, however at some stage it was decided that a lot of the marks would be stored in SCIMS. Whilst the majority of the marks are stored in SCIMS, some are not. Some of the marks form part of the State Control Network, and they are the manual copies (printed versions/photocopies) of what is stored digitally.

The format of the records are A4 and foolscap. Individual records have been hole punched. A small section of the records have been produced on photographic film. Records were removed from ring bound folders and placed in separate archival folders to maintain original arrangement created by department. Records are not any sequential order.
