Standard Survey Marks Regulations 1935

These regulations are the Standard Survey Marks Regulations 1935.

[Regulation 1AA inserted: SL 2021/151 r. 4.]

In these regulations —

Authority means the Western Australian Land Authority established by the Land Information Authority Act 2006 section 5.

[Regulation 1A inserted: Gazette 29 Dec 2006 p. 5911.]

All Standard surveys shall be performed under the instructions of the Surveyor General, and must be carried out by Surveyors licensed under “The Licensed Surveyors Act 1909.”

No Standard surveys shall be accepted nor approved by the Surveyor General unless same are in accordance with these Regulations, and such amendments thereof, as may from time to time be authorised.

A micrometer theodolite, or other theodolite approved by the Surveyor General, of not less than five inches in diameter, and with sensitive bubbles, shall be used on all Standard surveys, and angles read with the greatest possible accuracy. At least four repetitions of each angle shall be made, both verniers or both microscopes being read at each repetition, and the whole of the readings being recorded in the field record. One half of the repetitions of the angles should be taken with circle right, the other with circle left, and a note to this effect must be made in the field record.

[Regulation 3 amended: SL 2021/151 r. 5.]

Linear measurements shall be made with a steel or invar band, tested frequently with the Authority’s standard. A constant tension, to be shown in the field record, shall be applied and measurements corrected, where necessary for temperature. The temperature shall be observed as each length is taken, and recorded in field notes. The method of chaining shall be as approved by the Surveyor General.

[Regulation 4 amended: Gazette 29 Dec 2006 p. 5912; SL 2021/151 r. 6.]

All work performed in the field, with temperature and other corrections shall be fully recorded, while in each field record the temperature and tension at which the chain used is standard shall be plainly noted. Each page of a field record where notes appear shall be initialed by the Surveyor and shall bear the date on which the survey was made.

The following certificate shall be signed by the Surveyor at the end of the field record —

This is to certify that these field notes have been taken in the field by me personally and are the actual results of the observations and measurements

The limiting error of closure shall be one half link per mile: provided that, in special circumstances, approved by the Surveyor General, any other limit may be allowed.

The Standard Survey Mark shall be of such a nature as may be determined upon by the Surveyor General

At street or road intersections, the position of the Standard mark shall, as far as possible, be determined with due regard to the nature and convenience of traffic, but subject thereto, the mark shall be placed in such a position as to form a starting point for the standard traverse of such streets or roads, and to enable radiations to be recorded to the corners of each section.

Accurate measurements shall be made from the Standard Survey Mark to each section corner and the angle to the standard traverse carefully observed. The distance between each section corner across the street or road shall be carefully measured, and each section corner be connected to any building, wall, or other improvements in the vicinity.

Field notes and plans of all Standard surveys shall be lodged with the Authority. The plans shall be drawn to a scale approved by the Surveyor General, and in such a manner as to show clearly the details at the street corners.

[Regulation 10 amended: Gazette 29 Dec 2006 p. 5912.]
