Definition

Topographic surveying is used to determine the location, shape, and physical characteristics of the natural world and build environment.

Workflow

As part of a topographic survey, team members from Hawkins and Associates Engineering typically follow these steps:

  1. Coordinate the needs for the topographic survey.
  2. Plan the topographic survey.
  3. Perform research of any as-builts for facilities or infrastructure at the site of the topographic survey.
  4. Execute the field survey.
  5. Review, process, and adjust the raw measurements and other data provided by the field survey.
  6. Draw the topographic survey from the field measurements. Prepare intelligent models of the ground surface, road alignments, and other site features as needed.
  7. Prepare the topographic survey work product.
  8. Review and deliver the topographic survey work product.

Work Product

The work product from a topographic survey could be paper maps, digital maps in PDF format, or digital maps in CAD drawing files. The topographic surveying work product needs to be accurate, visually appealing, and convey the correct elements.

Technology

Team members from Hawkins and Associates use the latest surveying technology to accurately and efficiently create topographic mapping products. These technologies include aerial photogrammetry, GNSS surveying instruments, robotic total stations, surveying software to process raw data, and AutoCAD Civil 3D.

Coordination With Others

As part of the topographic surveying process, team members from Hawkins and Associates regularly work with land developers, civil engineers, structural engineers, architects, and government agencies involved in the planning of private development projects or public infrastructure projects.
