Survey Marking on Concrete – Salt Lake City – Utah
A survey marking on a concrete sidewalk in Salt Lake City, urging workers to proceed with caution, likely due to electrical utilities in the area. Salt Lake resides in the urban corridor known as the Wasatch Front that runs between Ogden and Payson.
Survey markings on pavement are temporary or semi-permanent symbols, lines, or indicators used by surveyors and utility workers to convey information about underground utilities, construction projects, or property boundaries. These markings are typically made using brightly colored spray paint, chalk, or flags to ensure visibility. Each color corresponds to a specific type of utility or purpose, following standardized color codes set by organizations like the American Public Works Association (APWA). For example, red indicates electrical lines, blue represents potable water, yellow marks gas or oil lines, and green highlights sewer or drainage lines. These markings are crucial for safety and precision in excavation and construction projects.
The markings help contractors, engineers, and workers avoid damaging underground infrastructure during construction or repair work. They may also indicate elevation points, property boundaries, or planned routes for utilities or structures. Surveyors use symbols like arrows, numbers, or letters to provide additional details about measurements, angles, or directions. It’s important to note that these markings are temporary and will fade over time or be removed after the project is completed. Observing these markings helps ensure projects proceed safely and efficiently, minimizing the risk of accidents or costly damage to critical utilities.
