Sleeve and Penetration Schedule Guide
How to review sleeve and penetration schedules for location, size, trade ownership, firestopping, structural openings, and installation sequence.
A sleeve or penetration schedule lists openings needed for pipes, ducts, conduits, cable tray, and other services passing through walls, slabs, beams, decks, and rated assemblies. It is most useful when every opening can be traced to a drawing location and trade owner.
The review goal is to confirm that openings are complete, correctly sized, structurally acceptable, and coordinated with firestopping before concrete, masonry, or framing work makes changes expensive.
Items to Check
Start by matching each schedule row to a plan mark, elevation, detail, and system route. Then verify that the opening size accounts for pipe outside diameter, insulation, movement, firestop system, sleeve material, and installation tolerance.
- Opening mark, sheet reference, grid location, and elevation.
- Trade owner and system served.
- Sleeve or blockout size, shape, material, and fire rating.
- Structural review for openings through beams, walls, slabs, or decks.
- Firestopping, waterproofing, acoustic, and smoke-seal requirements.
Common Problems
The most common sleeve errors are missing openings, openings placed from stale routing, sleeves that do not account for insulation, and penetrations through rated assemblies without a compatible firestop detail.
A good schedule is not just a list. It is a coordination record that connects layout, structure, MEP routing, and life-safety performance.
