The construction of an airport, an industrial facility or a residential building needs careful planning before the architect begins with the design of the building. The entire construction process begins with the inspection of the entire construction site. Topographical surveying is a procedure in which surveyors assess the distance, directions, and region of the Earth’s surface on which the building or facility will be built. Surveying technicians help surveyors to perform this task. Surveying technicians collect geographic data about a location and make estimates to present to people interested in a particular piece of land. The data collected can be used in legal documents such as deeds and leases. They must be proficient in the use of computer drawing programs and use modern technologies such as the Global Positioning System to find landmarks. Below are the duties and responsibilities of a professional surveyor technician:
calculate
A series of calculations are required to identify the actual size and outline of a parcel of land. A surveying technician is tasked with making an accurate and correct estimate of the surveyed terrain. The accuracy of its calculation is crucial in planning the structure to be built on the site. Urban planners and real estate developers are the ones who usually request topographical surveys.
Inspect existing structures
In addition to identifying the actual size and possible usefulness of undeveloped land, a topographical technician is also in charge of carrying out surveys of urbanized and improved urbanizations. His work includes measuring and examining infrastructure such as roads, bridges and buildings.
Report Findings
After collecting all the data on the site, the inspection technicians must prepare a report of their findings. If the technician is employed by a government agency, the result of their work will be a public record. Although this does not indicate that he has to prepare his report according to public requests, but it does mean that he will be responsible for the content of the report. He must be able to justify the accuracy of his data and how he came to his conclusions.
keep notes
Since most of the data collected from a survey will be included in a detailed report, it is essential that a technician keep complete and detailed notes while on site to ensure the accuracy of their data. Field notes must be precise, orderly and understandable. The notes must be legible so that the person responsible for recording the data can easily understand the notes that he or she has taken.
