In construction drawings, what do dashed lines typically represent?

Dashed lines in construction drawings are typically used to represent hidden elements. These hidden elements can include features such as plumbing or electrical lines, structural supports, and other components that are not visible in the current view or elevation of the drawing. Representing these elements with dashed lines allows for a clearer understanding of the overall construction design while indicating that these features exist behind the surfaces that are visible on the plan or drawing.

This method of representation is important for ensuring that all parties involved in the construction process, from architects to builders, have a comprehensive understanding of the full scope of the project. It aids in avoiding potential conflicts during the construction phase, as the dashed lines indicate that there are elements that may need to be accommodated or considered when planning and executing the build. Thus, recognizing dashed lines as indicators of hidden elements is crucial for the correct interpretation of construction documents.
