Chase

What is Chase?

Chase, A recessed channel or groove in walls or floors designed to accommodate pipes, wires, or other building systems

Description

Chase is a recessed channel, groove, or cavity built into walls, floors, or other building elements to accommodate pipes, electrical conduits, ducts, or other building systems while maintaining clean, finished appearances. These planned openings enable efficient routing of utilities and building systems without compromising structural integrity or requiring surface-mounted installations that could affect aesthetics or functionality.

Purpose includes concealing building systems, maintaining clean appearances, protecting utilities from damage, and enabling efficient system routing. Quality chase design and construction are essential for both functional performance and aesthetic appeal.

Types include wall chases for vertical routing, floor chases for horizontal distribution, ceiling chases for overhead systems, and specialty chases for unique applications. Each type serves specific routing requirements and installation conditions.

FAQs

  • Can chases be added to existing buildings?

    Yes, but it can be challenging and often requires structural analysis, as existing construction and codes may limit modifications.

  • How big can chases be without affecting structure?

    The allowable size depends on the structural design and location and typically requires engineering analysis to confirm integrity.

  • Do chases need fire protection?

    Yes, when they penetrate fire-rated assemblies, fire-stopping and proper sealing are required to maintain fire resistance.

  • Can multiple utilities share the same chase?

    Often yes, provided proper separation is maintained and code requirements are met for electrical, plumbing, and mechanical systems.

  • How do you waterproof chases in exterior walls?

    By using proper flashing, sealants, and drainage details to prevent water infiltration while maintaining access.

  • What’s the difference between chases and sleeves?

    Chases are continuous vertical or horizontal channels, while sleeves are individual penetrations for specific utilities.

  • Do chases require special permits?

    They may require permits if they affect structural elements or fire-rated assemblies; local code requirements should be checked.

Fun Fact

Fun Fact: The term “chase” in construction comes from the French word “chasse,” meaning to hunt or pursue, reflecting how utilities “chase” or follow these pathways through buildings.
