What color coding is used for survey markings in the utility color coding system?

In the utility color coding system, survey markings are indicated by the color pink. This color specifically signifies the location of proposed excavation or underground facilities in relation to potential future developments. The use of pink helps to differentiate these markings from others that correspond to existing underground utilities, ensuring clarity and facilitating safer excavation practices.

Understanding the purpose and context of each color in the utility color coding system is essential for professionals in the field, as it promotes awareness and reduces the risk of accidents during excavation. Other colors in the system are designated for different types of utilities, such as red for electric power lines and yellow for gas, oil, or steam, but pink is unique to the survey marking category.
