Structural Opening Review Guide
How to review structural openings for ducts, pipes, sleeves, stairs, shafts, doors, louvers, roof curbs, and equipment access.
Structural openings allow building systems, circulation, equipment, and architectural elements to pass through framing, walls, slabs, decks, and foundations. Missing or undersized openings cause RFIs, field cuts, reinforcement changes, and installation delays.
The review should confirm that every required opening is shown in the right structural element with the right size, location, edge distance, and reinforcement detail.
Openings to Track
Opening needs come from many drawings. MEP routes, architectural features, elevators, stairs, louvers, doors, roof equipment, and site utilities can all require structural coordination.
- Duct, pipe, conduit, cable tray, and sleeve openings.
- Shafts, stairs, elevators, roof hatches, and access openings.
- Door, window, louver, and storefront openings in structural walls.
- Roof curbs, dunnage supports, skylights, and equipment penetrations.
- Foundation wall penetrations for site utilities and drainage.
Review Sequence
Start with the systems that need the largest or most constrained openings, then confirm smaller penetrations and sleeves. Large openings affect framing; small openings often affect firestopping and field layout.
Helonic can help by flagging places where MEP or architectural requirements appear to cross structural elements without an obvious coordinated opening.
