The Importance of Land Surveyors in Civil Engineering

    The Importance of Land Surveyors in Civil Engineering

    Surveyors are an enigma to many people, but they are commonly seen all over the country. It’s likely you’ve seen them while driving through your hometown, out on vacation, or when headed to work. They are kind of hard to miss; they have a camera, tripod, and other equipment with them to survey a piece of land they’ve been assigned. If you’ve always wondered about what it is they do and their importance in civil engineering, wonder no more.

    Prevent Chaos in a Chaotic World

    Surveyors help to prevent chaos in a chaotic world. If surveyors weren’t able to efficiently perform their job duties, or we didn’t have the profession, civil engineering would not be as detailed as it is today. Surveyors help to survey the land that all of the following are constructed on:

    • Dams
    • Tunnels
    • Bridges
    • Highways
    • Railways
    • Irrigation
    • Ports
    • Airfields
    • Sewer lines
    • Reservoirs
    • Charting of streamlines, coasts, and waterways
    • Oceanographic charting
    • Fix state and national boundaries
    • Create topographic maps of Earth’s land surface

    Surveying is a required part of civil engineering because construction companies would not know what the final version of a project would look like ahead of time. It would be more difficult to put the pieces of the puzzle together during construction.

    Without surveyors, none of the aforementioned projects can be constructed correctly. The only way to measure land is to do so via a survey. It is the same measurements and data collected when a homeowner has a survey conducted on their property prior to listing it for sale or before constructing a fence along the property line.

    Various Survey Classifications

    There isn’t just one type of survey classification either. There are at least nine different types of surveying projects that surveyors complete within civil engineering. Those nine categories include the following:

    • Land: Used to determine the boundaries of parcels of land. Also referred to as a property survey.
    • Control: Used to determine vertical and horizontal positions for control points.
    • Topographic: Used to create a map of an area that has both man-made and natural features.
    • Reconnaissance: Used to explore a site for its infrastructure availability.
    • Engineering: Used to collect data for the design of various engineering projects.
    • Location: Used to set work for construction to begin on the land.
    • Preliminary: Used to collect data for the design and planning stages of engineering.
    • Route: Used to plan, design, and layout the route of canals, highways, railways, pipelines, and any other infrastructure that is linear.
    • Mine: Used to collect data for mining operations.
    • Astronomic: Used to collect longitude and latitude and azimuth when observing astronomical data.
    • Construction: Used to establish grades, lines, and points and staking engineering works well after plans have been finalized and the design of the structure has been completed.
