Surveying is classified as a learned profession because the modern surveyor needs a wide background of technical training and experience and must exercise independent judgement. A surveyor is a semi-professional who is the leader of a small, but expert team, usually consisting of the surveyor with one or more survey assistants. A surveyor must have a thorough knowledge of mathematics, particularly geometry and trigonometry and calculus, a solid understanding of survey theory and instruments. They must also have a thorough knowledge of methods in the areas of geodesy, photogrammetry, remote sensing, cartography and computers, with some competence in economics (including office management), geography, geology, astronomy and town planning, and a familiarity with laws pertaining to land and boundaries. They are governed by a professional code of ethics. The surveyor, as the leader of the team, will be required to make most of the decisions necessary for the smooth running of the team to ensure that the required tasks are fulfilled.
Responsibilities of a Surveyor
The responsibilities of the surveyor are many and varied, but can generally be reduced to the following.
i) Responsibility to the Task
The surveyor is responsible for completing the task required in the most efficient manner and in the time available. All effort must be made to ensure that the information supplied by the surveyor is as accurate as is possible to complete the task. Not all tasks require the same order of accuracy. By an understanding of the task the surveyor must decide on the accuracy to be achieved.
ii) Responsibility to the Client or Employer
The surveyor has a responsibility to the client or employer to produce what the client requires, within the budget restraints. This may need patience and tact in explaining to the client the limitations to a task.
iii) Responsibility to the Community
The surveyor has a responsibility to the community in general, to ensure that work undertaken by his team does not damage property or interfere with members of the community. Permission must be sought before accessing private property or before removing trees or shrubbery to enable survey measurements. The surveyor has a responsibility to protect the public in the purchases and sales of land.
iv) Responsibility to the Team
The surveyor, as the leader of the survey team, has a responsibility to the members of that team and must ensure that their needs are met regarding their leave, pay etc. The surveyor has a responsibility to ensure that all members of the team receive the training needed, not only to complete the task at hand, but also to enable them to advance within their chosen professions.
Role of a Surveyor
The role of the surveyor is that of the leader of the team. With that role come the responsibilities outlined above. The role of the surveyor is to perform the measurements necessary to complete any task required.
Tasks of a Surveyor
The tasks performed by a surveyor will depend on which branch of surveying they practice in. The most common tasks involve the determination of height and distances. For the Cadastral Surveyor, the main tasks involve the determination of property boundaries. For the Topographical Surveyor, the main tasks involve the location of detail on the earth’s surface for the production of maps. For the Engineer Surveyor, the main tasks include the setting out of buildings, sewers, drains, bridges and roadways; determining areas and volumes of regular and irregular figures; the preparation of detailed drawings and plans. For the Mine Surveyor, the main tasks include the setting out of mine lease boundaries and the calculation of end-of-month volumes.
Responsibilities, Role and Tasks of a Survey Assistant
The survey assistant is an important and integral part of any survey party. Most measurements performed by a surveyor require the assistance of another person, be it levelling with a staff man or distance measurement with a chainman.
Responsibilities of a Survey Assistant
The main responsibility of the survey assistant is to assist the surveyor in performing his or her tasks.
Role of a Survey Assistant
As mentioned above, most surveys require at least two people, the surveyor and another, to be able to undertake the necessary measurements. The role of the Survey Assistant is to be that second person in the performance of survey measurements.
Tasks of a Survey Assistant
The tasks performed by the Survey Assistant will depend on what the surveyor is undertaking. The primary task for the Survey Assistant will be as a chainman and a staff man, although he/she may also be required to make sure that the equipment is kept clean and ready to be used. The Survey Assistant will also look after the vehicle, making sure that it is refueled, cleaned and correctly packed for use. Each morning the Survey Assistant will pack the vehicle with the survey equipment needed for the day. While on the work site, the Survey Assistant will also perform the manual labour, such as clearing lines of sight of vegetation and clearing around survey control points. While traversing, the Survey Assistant will also work ahead of the Surveyor, plumbing tripods and targets over control points for the Surveyor to observe to. In general, the Survey Assistant will perform whatever task is needed to help the surveyor to complete their work.
