Miscellaneous metals estimating, item by item

Where misc. metals lives in the specs

In CSI MasterFormat, metals are Division 05. Misc. metals usually means 05 50 00 Metal Fabrications, but the scope is split across several sections, and the split varies by project manual:

Section	Typical content
05 12 00 Structural Steel Framing	Frame, connections, often some "structural" misc.
05 21 00 Steel Joist Framing	Joists, bridging
05 31 00 Steel Decking	Floor and roof deck, closures
05 40 00 Cold-Formed Metal Framing	Load-bearing CFS
05 50 00 Metal Fabrications	Loose lintels, embeds, bollards, ladders, supports, frames, trim
05 51 00 Metal Stairs	Pan stairs, landings, stringers
05 52 00 Metal Railings	Pipe and picket rails, guards, handrails
05 53 00 Metal Gratings	Bar grating, trench covers
05 70 00 Decorative Metal	Architectural metalwork

Read the 05 50 00 "Summary" and "Related sections" paragraphs first. That's where you find out that the elevator pit ladder is in 14 20 00, the countertop supports are by the casework subcontractor, or the canopy frames are "delegated design by fabricator."

Also check what AISC 303 says about classification. It lists items that count as structural steel and items that don't, and it helps settle arguments about whether a lintel or a loose bearing plate belongs to the frame package.

Take off item by item, from every discipline

Misc. metals is rarely drawn on the structural framing plans. Go sheet by sheet:

• Architectural elevations and wall sections: loose lintels, shelf angles, relief angles, canopy and sunshade framing, screen supports.
• Architectural details: countertop and toilet partition supports, overhead door frames, corner guards, edge angles, thresholds.
• Floor plans: pipe bollards at doors, column guards, ladders, pit covers.
• Civil and site plans: site bollards, gates, trench drain frames, dumpster enclosure steel, guardrails at walls.
• MEP sheets: pipe stands, equipment dunnage, unistrut or steel supports, roof hatch ladders. Notes like "supports by misc. metals contractor" are easy to miss.
• Structural general notes and details: embed plates, angle frames at deck openings, elevator sill angles and divider beams.

Keep each item type on its own line with the sheet and detail reference. When the GC asks "where's that from," you can answer in seconds.

Lintels: the most missed item

Loose angle lintels show up on architectural elevations and wall sections, not on structural framing plans. Count every masonry opening, including louvers and mechanical penetrations. Then:

1. Size each lintel from the lintel schedule or typical detail by opening width. Typical schedules step up angle size and add a second angle or a plate as spans increase.
2. Add bearing at each end. TMS 402 requires at least 4 inches for lintels supporting masonry veneer, and many specifications and details call for 8 inches. Use what the detail says.
3. Note finish. Exterior lintels in veneer walls are commonly specified hot-dip galvanized, and the BIA's technical guidance discusses corrosion protection and flashing at lintels.
4. Check who installs. Loose lintels are usually furnished by misc. metals and set by the mason. Say so in the proposal.

Example (illustrative): a 6'-0" opening with an L6x4x5/16 lintel per schedule, 8 in bearing each end.

length = 72" + 8" + 8" = 88" = 7.33 ft
weight = 7.33 ft × 10.3 lb/ft ≈ 75.5 lb  (check the AISC Manual for the exact angle weight)

Twenty openings like that are about 0.75 tons, priced mostly in handling, cutting, galvanizing and delivery, not in steel.

Embeds, bollards and ladders

Embed plates. Count by type from the details that call them out, often on concrete, precast or structural sheets. Each type has a plate size, thickness and stud or anchor pattern. Price the plate, headed studs (usually welded), finish and handling. Embeds are usually furnished by steel and set by the concrete contractor. If you only furnish, say so, and agree on a delivery schedule tied to the pour sequence.

Bollards. Fixed pipe bollards are usually steel pipe (6 in and 8 in diameter are common) set in a concrete footing or core-drilled hole, filled with concrete and capped. Take off:

• Pipe diameter, schedule and total length including embedment.
• Footing: who excavates and pours, and footing size from the detail.
• Concrete fill and cap.
• Finish: shop primer, field paint (often safety yellow) or plastic covers.
• Removable or decorative bollards with sleeves, or crash-rated bollards with tested assemblies, which are a different product and price.

Ladders. Take off roof, pit and equipment ladders by height, with cages, extensions, walk-through rails and roof hatch coordination. For workplaces under OSHA general industry rules, 1910.28 requires fixed ladders installed on or after November 19, 2018 that extend more than 24 feet above a lower level to have a personal fall arrest or ladder safety system. A cage alone doesn't satisfy it. OSHA published a proposal in April 2026 that would change the 2036 deadline for existing ladders, so check its status before you advise an owner. If the drawings show a caged ladder over 24 feet, that's an RFI.

Stairs and railings: usually delegated

Metal stairs and railings are often delegated design: the fabricator's engineer designs them to code loads and submits calculations. When you see that, carry engineering, shop drawings and review cycles the same way you would for delegated connections. The building code sets guard and handrail loads (a concentrated load and a uniform load per foot), heights and opening limits. Price stairs by flight and landing and rails by linear foot with posts, returns and terminations counted separately. Terminations, wall returns and transitions take as much time as straight runs.

Pricing: by piece, not by ton

Misc. metals has many pieces per ton and a lot of handling, so cost per ton is a weak basis. Price by item:

• Material, with a minimum length or drop allowance for small pieces.
• Shop hours per piece by item type (cut, drill, weld studs, fit).
• Finish: galvanizing is usually priced by weight with a minimum charge per lot, plus freight to and from the galvanizer.
• Delivery: misc. often ships in many small loads tied to other trades' schedules.
• Installation, if you're installing. Many items are furnish-only.

A misc. package that comes out at the same $/ton as the frame is almost certainly underpriced.

Write the splits into the proposal

Scope gaps live between trades. Embeds may be "furnished by steel, installed by concrete." Lintels may be "by mason" on one sheet and "by Division 05" in the spec. MEP supports may be in both. List every item type with furnish, install and finish so the GC can level bids line by line.

Where RenderDraw fits

The hard part of a misc. metals takeoff is finding everything spread across architectural, civil, structural and MEP sheets. RenderDraw's AI takeoff proposes counts and lengths across disciplines with the source sheet on every row and puts uncertain items in a review queue. Pricing, finish and scope splits remain your call.
