The process of following the route of a facility is accurately referred to as tracing. Tracing involves using various tools and techniques to visually or mathematically follow the path or network of a facility, which could include utilities, pipelines, or other infrastructure. This process is essential in fields like engineering and construction, where understanding the layout and connections of systems is critical for planning, maintenance, or repairs.

Tracing helps professionals ensure that they are aware of existing structures, minimizing the risk of damaging utilities during excavation or construction work. It enables a clear understanding of how different parts of the facility integrate and function together, which is critical for making informed decisions regarding modifications or enhancements to the system.
