Conducting topographical surveys helps engineers, builders and various professionals understand the shape, form, level and geographical position of the earth. The information that is derived from such surveys can be used to identify the mapping and contouring of the land, which makes the data vital during the planning phases of construction and developmental projects.
Importance of Surveys
The maps and contours that are created during a topographical survey serve as the base map of the project regardless of which type of construction is being implemented. Bridges, roads, residential buildings and commercial structures are among the projects that require topographical surveys.
Topographical surveys are performed both above and below ground level. Soil density, manholes, trees, walls and walkways are some of the materials or areas that are examined. Each feature that is present on the land is relevant to a survey.
Topographical Survey Process
Land surveyors follow a number of steps to make sure that the topographical survey is accurate. The framework of the survey is based on the establishment of a horizontal and vertical control. Determining enough horizontal location and elevation of the ground points ensures that there will be sufficient data for plotting for map preparation.
Natural and man-made features on land may need to be found depending on the purpose of the topographical survey. Distances, volumes, angles and elevations of earthwork are computed and topographic maps are drawn. Click here for .
Reasons for Using Topographical Surveys
- Topographical survey results are used by various professionals, including engineers, architects and geologists. Government agencies and institutions may need topographical surveys to validate the ownership and status of land.
- Topographic maps are useful as references during the process of creating the geographical map of the land.
- When topographical surveys need to be conducted, it is advisable to hire professional land surveyors and firms.
- Surveys provide all the essential data about the land. They give you details such as the value, strength and life of the land.
- Topographic surveys are used to calculate measurements like length, dimensions and elevation of the land, subsequently providing data that facilitates mapping and contouring. The data is also useful for identifying the configuration of natural and cultural land features.
- Topographical surveys can also be used by archaeologists when they need to examine findings before a construction project begins.
Surveys are conducted for safety purposes. Modern and technologically advanced equipment can e used to perform surveys in situations where current underground records are ambiguous incomplete or outdated. It is safe to consult the experts instead of continuing. This is crucial for making sure that all the data about the land has been updated before the construction project starts.
Topographical surveys continue to be essential for understanding what the earth constitutes. Professional land surveyors consist of experienced, skilled and accredited individuals who utilize the latest techniques and technology to carry out their work and provide all the specified survey requirements.
Quality survey services range from GPS surveys to both small and large scale land surveys. Products and technologies in the industry are designed to evaluate and mitigate any risks that are associated with infrastructure projects.
