Miscellaneous metals is the one trade where the specification section is the least reliable place to find the scope. Stairs, railings and the named fabrications in Division 05 50 are real and countable. The bulk of the long tail this trade prices is scattered one item at a time across every other discipline's drawings, and nobody collects it into one list for you. That's the job — sheet by sheet.
Division 05 50: what the section itself actually covers
- Metal fabrications, complete — loose angles, bent plates, bollards, corner guards, cat ladders, gratings, checkered plate, elevator pit ladders and sill angles, counted item by item, not swept up in a single allowance.
- Metal stairs and railings — steel stairs with pan or grating treads, handrails and guards, wall rails, supplied and installed with the shop finish as specified.
- Delegated connection and guard design — engineering and stamped shop drawings for stairs, guards and ladders where the documents delegate that design to the fabricator. A real engineering cost, not a formality; extract the delegation language rather than assuming it's covered elsewhere.
- Loose lintels and shelf angles, supply — where the documents assign supply to metals. Masonry installs these, but someone still has to supply them, and silence in the spec doesn't mean nobody's on the hook.
What's genuinely not yours, even from this same section: the structural steel frame, joists and deck belong to structural steel — worth noting at all anyway, since that boundary is exactly where a scope gap tends to open. Cold-formed framing and stud walls are drywall's scope even when the word "metal" sits right in the note; it's the most common false-positive in the whole trade.
Where the rest of it hides
The civil sheet
Bollards, most often — a site-plan callout with an embedded plate detail that never crosses into the building spec.
The mechanical drawings
Cat ladders, roof access, and the crane- and hoist-adjacent steel: runway stops, crane rail fixings, davit bases. These sit in the gap between the crane vendor's package and general steel scope, and specs don't reliably assign them to either by default. Where the crane vendor's own scope doesn't explicitly claim this steel, it needs a name on it before bid day — the kind of item that surfaces when the crane installer shows up and asks who's supplying the rail stops.
The architectural sections
Sill angles, corner guards, ornamental and feature work. Feature stairs, glass or cable railings and architectural screens read like an upgrade to standard fabrications, but they're a different pricing category entirely — the finish system attached (polished stainless, a custom powder coat, a proprietary cable system) drives cost far more than steel tonnage does. Extract these with the finish system named specifically, not flagged as "feature item."
The elevator shop drawings
Pit ladders, divider beams and sill angles built to the elevator supplier's own layouts, which routinely differ from what the architectural drawings show.
The specialty-door package
Overhead and coiling doors need guide angles, jamb steel and hood supports, and this is a genuine no-man's-land: the door supplier is watching for the steel to already be there, and the misc metals package doesn't price it automatically just because it's steel. Neither package prices this by default — silence here is the single most likely way it gets missed entirely.
Four things worth checking on every set
- Galvanizing and finish assignments. Hot-dip galvanized versus primed versus powder-coated is a real cost spread, and exterior items default to galvanized in most specs without the schedule repeating it on every item. Assume galvanized outdoors unless told otherwise.
- Embeds and anchor bolts split. Supply by metals, placement by concrete is the usual split — extract the actual words rather than trusting "usual." A missed embed isn't a paperwork problem; it's a site-drilled fix at cost, after the pour.
- Code-driven guard requirements. Guard heights and loads are frequently pulled from code by reference rather than drawn explicitly, and the delegated engineer prices to the code minimum regardless of what the drawing shows — the drawing alone can understate what's actually required.
- Anything you haven't swept yet. There's no substitute for a pass over every sheet in the set. Division 05 50 names the categories; the drawings scattered across every other discipline are where this trade's real quantity lives.
Who you're sharing the connection with
| Trade | What to reconcile before you price |
|---|---|
| Concrete | Embeds and anchor bolt placement, grout under base plates, and stair bearing — confirmed before the pour, not after. |
| Masonry | Loose lintel handoff: supply here, installation there. Confirm the split is stated, not assumed by either side. |
| Elevator | Pit ladders, divider beams and sill angles built to the elevator supplier's own layouts, which may differ from the architectural drawings. |
| General contractor | Hoisting, sequencing of stairs for construction access, and temporary guards during the build. |
