A boundary survey is critical for any structure construction. When intending to build a house, a good boundary survey must be performed beforehand. It is critical to conduct an examination to identify the physical boundaries of the property in order to avoid any future disputes. Typically, surveys are conducted by professionals who use instruments like GPS to record the boundaries of properties. Building within someone's else's property line can lead to problems later. If you discover that another person is building within their boundary, they could be in violation of your warranty if you have one. They could also claim ownership of whatever building project lies within their boundary. In addition, buildings that are not listed as part of the public record may be at risk for being demolished by their owner if they fall within his or her boundary. Therefore, it is important to obtain accurate surveys before starting any work on your property. Surveying tools include transit, rod, and chain. A transit is a telescopic device used by surveyors to measure distances. The transits range in price from $20,000 to $100,000. Rods are similar to transits but are hand-held instead of tripod supported. Hand-held rods are usually made of steel with a plastic handle attached. Chain is used to mark out property lines. This tool is available at home improvement stores and costs about $10 per hundred feet.
