What is shown on a utility plan?

A utility plan is specifically designed to provide essential information regarding the different utility systems within a construction project. It prominently displays the layout of utility services such as stormwater drainage systems, sanitary sewer piping, water supply lines, and electrical as well as communications infrastructure. This level of detail helps contractors and engineers understand the placement and relationship of these utilities to the building and surrounding environments, ensuring they can plan for installation, maintenance, and compliance with municipal regulations.

The other choices pertain to elements that would be found on different types of drawings. For instance, the building layout focuses on the overall design and spatial organization of the structure itself, while interior dimensions primarily detail room sizes and layouts within the building. Structural supports would be outlined in structural drawings, focusing on the load-bearing elements of a structure.
