19. In respect of strata surveys —
|
Observations to trigonometrical stations |

Authorised marks |
25. The following marks are authorised for the type of use specified in relation thereto:

Original field notes to be submitted |
27. All title surveys related to land transactions, such as subdivisions, transfers and re-locations of boundaries, shall be recorded in field books of the authorised pattern and submitted to the Chief Surveyor on completion of such surveys. |
Certificate to be signed |
28.—(1) The first diagram page of the field notes of every survey shall bear a certificate signed by the registered surveyor in the following form:
