Importance of Topographical Survey for a Building Project

Posted by Calvada on November 30th, 2015

Topographic surveys are meant to determine a land's geographical condition. Data about your land will be useful when identifying the map and the land's contours. Hence, the surveys are valuable during the planning phase of construction and developmental projects. Topographical surveys will create contours and maps to be used as the base map for a project, regardless of its nature. Hence, they are useful for residential buildings, bridges, roads, commercial structures, and other developmental structures. 

You may need to conduct a topographical survey to create a base map for a driveway or a road, too, so you can easily show the lines of easements and perimeter boundary lines that are on or may cross the property. This can help designers to show agency required setbacks and zoning, too. 

A topographic survey is conducted below and above ground level. The materials and area to be examined will cover soil density, trees, utility poles, walkways, walls, wells, manholes that are present in the land, and others. All aspects found on your land should contribute to the results of the topography survey. In most cases, topographic surveys often follow five crucial steps:

  1. The establishment of vertical and horizontal control to serve as the survey's framework
  2. Determine ample elevation of ground points and horizontal location to make sure that there is enough data for plotting when a map is being prepared
  3. Locate man-made and natural features that may be required by the survey's purpose
  4. Compute angles, distances, elevations, and volumes of the earthwork
  5. Draw the topographic maps. 

In a topographic survey, different details about a land must be collected to determine its live, value, and strength. Accurate measurements on the breadth, length, height, elevation, curves, and dimensions of the land will be calculated. Each aspect surveyed matters to the map and the contouring of the land. The results and outcome of a topographic survey are useful when configuring the land's cultural and natural features. 

Topographical surveys are useful for various professionals like geologists, foresters, promoters, and architects when starting a building project. Government institutions and agencies rely on the results of topographical surveys, too. Maps developed by the survey may contribute to the land's actual geographical map. For these reasons, you must be sure to hire a reliable company that specializes in conducting accurate and comprehensive topographical surveys with a lot of experience in the industry, especially in working on different types of building projects. Look for a topographic survey company that has professional surveyors and high-end equipment to achieve accurate and reliable land surveys.
