Question: 1 / 400

What does ‘PC’ stand for in surveying terms?

Point of Contact

Point of Curve

In surveying terms, ‘PC’ stands for Point of Curve. This term is significant in the context of curved alignments, particularly when dealing with roads, railways, or other linear infrastructure. The Point of Curve is the location at which a curve begins. This is critical for calculating the geometry of a curve, including the radius, length, and the transition to straight sections of a path.

Understanding the concept of the Point of Curve helps surveyors in accurately laying out paths and ensuring that the curvature is properly accounted for in the design and construction process. This foundational knowledge is essential for maintaining safe and efficient design standards in various surveying projects.

The other terms, while potentially relevant in different contexts within surveying, do not specifically define the abbreviation ‘PC’ in the same way.
