Surveying services come in various forms. Talk of property surveys, regional and town planning, the fit of mechanical machines and construction survey services. Therefore, a surveyor is in the middle of the design stage and building stage of a project.
Survey service providers tend to focus one area so that they deal with one type of surveyor services.
The land surveyor makes use of machines such as theodolites, levels, total stations, GPS and drones.
Surveying in Land Demarcations
Land surveyors who do divisions of land parcels are called cadastral or title surveyors. The South African Geomatics Council calls them Professional Land Surveyors.
Title surveys deal with boundaries and registration of land parcels. The most notable product of a land surveyor is a title deed. Title deed is a document of ownership rights of a piece of land.
Title survey data is filed and kept at the department of surveyor general, a public office that signs off and approves title surveys.
Sub divisions of farms, plots and residential land forms one of the most common type of title surveying.
Another type is the consolidation survey, where two or more registered land parcels are joined together to form one legal document.
Surveying In Infrastructure Development
Surveyors who focus on building projects are known as engineering surveyors, civil surveyors or site surveyors.
Site surveyors perform setting out surveys to align buildings, level and position of members of a building.
Roads, bridges, tunnels and stadia needs services of a surveyor before and during construction. First, surveyors take sizes and shapes of the land parcels to come up with maps. These maps are useful for the design of buildings. Then engineers use the spatial data to design buildings. Civil engineers need spatial data to come up with designs and drawings for site works. Finally, when an engineer has seen how the land terrain looks like and made his design, he needs the surveyor to put it to the ground.
During the building phase, setting out surveys takes place. Surveyors mark out points, lines and levels to guide site works.
