What is Surveying?

"It is better to invest a small amount to make sure than investing a large amount of uncertainty." Surveying means the detailed and accurate description of a place, determining the dimensions, existing elements, variations in altitude, landforms, etc.. The Surveying provides data, obtained by calculation methods and tools that allow the knowledge of the terrain, providing a basis for implementation of projects and works carried out by engineers or architects. Both being essential in the design stage and carrying out the work. The Surveying is primarily intended to represent graphically, through the plant surveying all the characteristics of an area, including Surveying, contours, existing features on site, length, area calculation, elevation points, magnetic north, geographic coordinates , geographical, etc.. The Surveying plan should be developed through use of appropriate equipment and methods of measurement and graphical representation considering the parameters, methodology and legislation to provide a survey work in accordance with technical standards. Not to be confused with Geodetic Surveying, because while the Surveying is intended to map a small portion of the earth's surface, the Geodesy is designed to map large portions. The area of ​​Surveying has become increasingly complex due to technological advances. As a result of these advances, which occurs in Brazil, both in small as in large urban centers, there is a dearth of professionals. With the resumption of economic growth in Brazil from the Lula government, it was found that there is a large gap in technology, the country was parked more than twenty years, where several courses on various areas have been closed, however you need to grow and have staff trained in dealing with Surveying, depend on various other activities such as construction, mining, railways, urban public works, transmission lines, industrial dimensional control, paving, architecture, landscaping, etc.. In the case of Surveying equipment of last generation, the most widely used is the Total Station, because it allows all the data collected in the field are recorded and then downloaded to the computer where you will be prosecuted. This equipment allows not only bring the field data as well as burn data to be used in the field, ie hold the lease for an area or deployment points, the coordinates are recorded in the total station to be materialized in the field. This avoids many errors and streamlines the service. The G.P.S. (Global Position Sistems) has become indispensable to the Surveying, as well as tie the area in UTM coordinates officers, allows the mapping of large areas accurately and in a short time.

By analyzing the stages of construction can be seen that this activity is involved in mainly urban and social development. The builder has the idea of ​​buying a property to build her a real estate development. The first thing that the builder should do is request a service from Surveying of the land cadastre. The survey is not just to be sure the footage of a given area is much more than that in the hands of the Surveying, the manufacturer will evaluate not only the price, but also whether their investment will will bring financial returns. The survey provides a real vision of the land. The verification of the actual geometry of the terrain and altitude brings security to the engineer or architect who is conducting a study of mass. A survey and determined, you should consider all elements in the property, such as through wires, internal streets, lined walls and fences, demarcation landmarks, trees, drainage boxes, poles, drains, existing buildings, bordering buildings, indicating direction of traffic, the existence of rivers or streams near the land, spot elevations, contours, slopes, rocks, etc.. It follows therefore that it is important to carry out surveying the land before investing blindly in real estate business. In the implementation phase of the work, the Surveying serves as a technical tool to avoid errors, we can cite the following services: "Demarcation of the boundaries of the land, leasing leveling of boreholes, dividing the square of the work, location of posts, location of pillars , flatwork, monitoring of the pillars plumb, level the floors and ceilings, markings of recreational areas and garden, as-built work, etc.. Among the requirements of the Public Bodies (SERLA, River-Waters, and SMAC FEEMA) for approval of urban projects, some solutions are given by the Surveying, such as lashing the land in UTM coordinates use of RN (referential level) local county official., registration of vegetation for approval with the SMAC and Parks and Gardens, etc..

Before you purchase, before building before demarcate, fence or wall before, before designing, consult a professional of Surveying, avoid unnecessary headache.
