A groove that goes through the floor to accommodate pipes or ductwork is called what?

• A. Chase
• B. Chafing
• C. Bridging
• D. Girders

Answer: (A)

A chase is the term for a channel or groove cut into a floor (or wall) to run pipes, ducts, or wiring. It’s specifically made to conceal and route these services cleanly without compromising structural members, and floor chases are common when you need to pass utilities between levels or through a slab. Chafing refers to wear from friction, so it’s not used for routing. Bridging describes a method of connecting or supporting framing between joists, not a groove for services. Girders are large supporting beams, not channels for pipes or ducts.
