Surveys are generally required by title businesses and companies lending money, for them to know that there aren't any structures encroaching on the property and any construction on the land will meet the prescribed construction codes. In that, one needs to be certain that the survey is done by a licensed land surveyor and not an inspection is conducted for granting loans. A land inspection report which is not conducted by a licensed surveyor is not accepted as an official land survey. Surveys are also required from the buyer’s perspective to ensure that the land measurements are correct according to the measurements specified in the documents.
Topographic surveys are land surveys which find the illustrations, advancements, structures, fences, slopes, trees, streams, land contours and other features of the land. These findings are then measured on the land for its elevations and it forms the contour lines on the topographical sheets. Topographical surveys are often demanded by the government authorities. They are also used by the engineers and the architects and also to upload on websites.
Surveys are increasingly used in the construction field and are used for inception and preparation of construction plan. Surveys are also used for routine maintenance afterwards.
Groundwork surveys are surveys which collects the positional knowledge on a foundation which is now remedied. Foundation survey is needed if one is building up a custom home and it’s a document that depicts the schematic representation of the floor plan of the house with the slope or elevation readings of the entire floor plan. The elevation readings represent the low and high points of the foundation at any point of time. Foundation surveys are the baseline of the contour of the foundation of the building.
Deformation survey is a survey conducted to measure the change of shape of an object because of its surrounding stresses. Deformation surveys are a part of applied surveying which relates to soil and rock stability mechanics. The surveyor takes few dimensional positions on unique points of an object and watches the change after a period of time and measures the effect of stresses on the object which is the basis of soil testing.
Hydrographic surveys gather information for shapes of water, depth of the water table, bottom contours, records the water marks, route of the current, water ranges and other navigational functions. Bathymetric surveys are also a survey which offers an underwater map and the sea bed profile.
Geodetic surveys are conducted to measure the curvature of the earth in reference to the plane connecting two distant points far from each other. This survey along with others is instrumental in planning the foundation surveys and other engineering utilities.
