What is the term for an open space within a wall where wires and pipes run?

The term "chase" refers to an open space or a narrow passageway within a wall, specifically designed to allow for the safe and organized running of wires, pipes, or other utilities. This infrastructure component is crucial for maintaining the structural integrity of a building while providing a means to conceal and protect essential services from visible disarray and potential damage.

In construction and fire protection, understanding the layout and purpose of chases is essential, as they can also play a role in identifying fire hazards or planning for fire suppression systems. Utilizing a chase can facilitate the maintenance and upgrading of utility systems without significant structural disruption.

The other terms listed describe different concepts. For instance, a "channel" typically refers to a groove or a hollow area designed for flow, such as water, rather than housing utilities. A "soffit" describes an architectural feature that refers to the underside of an architectural element, often seen in eaves or ceilings, which does not pertain to utility installations. Lastly, a "bay" refers to a space created by a structural layout, often associated with larger compartments in a building, rather than a specific passage for utilities.
