In construction terminology, a chase refers to a recessed groove or channel created within a building structure to accommodate pipes, conduits, ducts, or other utility lines. Chases are typically formed during the building’s construction phase and are strategically located within walls, floors, or ceilings to conceal and protect the installed services while allowing access for maintenance or repairs when necessary.

Key Characteristics and Uses of Chases:

1. Concealment of Services: One of the primary purposes of chases is to conceal plumbing, electrical, HVAC, or other utility lines within the building structure. By recessing these services into chases, they are hidden from view, contributing to the aesthetic appeal of the interior space.

2. Routing Utilities: Chases provide a designated pathway for routing utilities through the building. This organized routing helps prevent tangling or interference between different services and facilitates efficient installation and maintenance processes.

3. Space Optimization: Chases help optimize the use of interior space by allowing services to be routed within walls, floors, or ceilings without encroaching on usable floor area. This is particularly important in modern construction, where maximizing usable space is a priority.

4. Access for Maintenance: While chases conceal utility lines, they also provide access points for maintenance or repairs. Access panels or removable sections of wall, floor, or ceiling can be incorporated into the design to allow service personnel to reach the utilities contained within the chase.

5. Fire Safety: Chases may also serve a fire safety function by containing utility lines within fire-rated walls or floors. This helps prevent the spread of fire and smoke through concealed spaces and contributes to the overall fire protection strategy of the building.

6. Soundproofing: In some cases, chases can act as soundproof barriers, helping to reduce the transmission of noise between different areas of the building. This is particularly relevant when routing HVAC ducts or plumbing pipes through walls or floors.

7. Customization: Chases can be customized to accommodate specific building requirements and the layout of utility services. They may vary in size, depth, and shape depending on the types of services being routed and the architectural design of the building.

In summary, chases play a crucial role in modern construction by providing a concealed pathway for routing utility lines while ensuring accessibility for maintenance and repairs when needed.

During the renovation project, the electrician installed new wiring in the chase located behind the drywall to power the additional lighting fixtures.
