Topographic Survey

topographic survey

Having a detailed Topographic Survey is the foundation for any successful Engineering and Architectural site design. By conducting a topographic survey at the conceptual stage of a project you will have an accurate base to work from to assess how a piece of land may have to be shaped and the amount of earth moving that will have to take place to build the site out. Topographic Surveys are also very commonly used in construction to quantify the amount of material moved on a construction site.

A topographic survey can best be described as a map showing the existing elevations and features of a piece of land. Topographic surveys can be completed using a combination of using instruments depending on the terrain, vegetation, tree canopy and proximity to exiting structures. Instruments used include:

  1. Robotic Total Station
  2. Real Time Kinematic GPS
  3. Drone/UASs Aerial Mapping

Typical features surveyed as part of conducting a topographic survey included:

  • Roads curb and sidewalk
  • Tops and toes of slopes also know as break lines
  • Existing manholes and services including inverts
  • Trees including calliper and dripline if required
  • Existing structures
  • Existing fences, walkways, stairs, retaining walls, landscaping, etc.
  • Shallow utility boxes and power poles

Once the field work is completed a 2D map will be drafted showing all the existing features surveyed a 2-dimensional map plan view map will be produced to scale. The map will also show the contours which are horizontal lines connecting user specified elevations. The relative spacing of the contour lines indicate how steep the terrain is. The closer the contours the steeper the terrain.
