CODE-DRIVEN FABRICATION · ENGINEERS ON STAFF · CA LIC #1136711

Code Compliance: OSHA, ADA, and Stamped Structural Steel

Most of what we build exists because a code requires it. We design to the code first and the drawing second.

Three regimes drive the majority of our fabrication work: OSHA and CAL-OSHA fall protection, ADA accessibility geometry, and California structural review. We have engineers on staff that design, draft, and stamp these structures and pull permits if necessary.

A compliant-looking structure and a compliant structure are different products

Every fabricator will tell you their guardrail is OSHA compliant. Fewer can tell you what load it was designed to resist, at what point, with what deflection, and produce the calculation that says so.

The difference shows up in three places: at plan check, at inspection, and after an incident. In the first two it costs money and schedule. In the third it costs considerably more.

We build to the applicable code, we say so before fabrication when a design drawing conflicts with it, and we produce the stamped calculation when a jurisdiction wants one.

1. Fixed ladder fall protection

  • California triggers at 20 feet. The federal rule triggers at 24.

    Cal/OSHA, Title 8 CCR §3277(g)(2) requires cages or wells on fixed ladders of more than 20 feet, to a maximum unbroken length of 30 feet. Federal OSHA, 29 CFR 1910.28(b)(9), sets its trigger at more than 24 feet. Cal/OSHA enforces the California standard in California workplaces, so a facility that inventoried at 24 feet has a four-foot blind spot.

    The trigger most facilities miss is not a height at all. Under 29 CFR 1910.28(b)(9)(i)(C), when a fixed ladder or any section of one is replaced, a personal fall arrest system or ladder safety system must be installed in at least that section at that time. That obligation applies today. Any fixed ladder installed on or after November 19, 2018 must already have one.

  • What we do:

    • Custom fall-arrest system fabrication and installation for existing ladders
    • New fitted fixed ladders with an approved fall-arrest system, and install
    • Ladder surveys counted against the California 20-foot trigger

    Related fall-protection work: 42-inch OSHA guardrail on mezzanine edges, roof edges, pits, and dock edges. Access platforms and landings. Toe boards. Self-closing safety gates at ladder and stair openings. Guarding around equipment.

3. Stamped structural design and permits

  • We have engineers on staff that design, draft, and stamp these structures and pull permits if necessary.

    That sentence covers the third regime, and in California it is the one that catches people out. An elevated structure inside a building has to resist lateral load, and its anchorage has to be designed into the actual slab, in the actual seismic design category, on the actual site.

  • What typically requires a stamp:

    • Mezzanines and elevated platforms
    • Equipment support structures carrying meaningful load
    • Guardrail on an occupied edge
    • Balconies, decks, and exterior elevated elements
    • Canopies and awnings, particularly for wind uplift
    • Anything attached to an existing building where the connection capacity has to be verified

    What we do: structural design, connection design, calculations, stamped drawings, permit application, and coordination with the plan checker and the inspector.

What our compliance posture actually means for you

  • We flag a code conflict in a design drawing before we fabricate it, not after it fails inspection
  • We produce the calculation package, not a letter that says it should be fine
  • We pull the permit and meet the inspector rather than handing that back to you
  • We tell you when a product you asked for will not pass, and what will
  • We count your ladders against the California 20-foot trigger, not the federal 24, so the inventory is the right one

Common questions

Are you licensed in California?

Miller 3 Engineering holds California contractor license #1136711. You can verify any California licence, including the classifications it actually covers, at the Contractors State License Board's Check-A-License tool on cslb.ca.gov.

Can you stamp drawings and pull permits?

Yes. We have engineers on staff that design, draft, and stamp these structures and pull permits if necessary. That covers mezzanines, platforms, guardrail on occupied edges, balconies, canopies, and structures attached to existing buildings. It is one of the main reasons clients choose a fabricator with engineers over a shop that only welds.

At what height does California require fall protection on a fixed ladder?

Above 20 feet. Cal/OSHA 8 CCR §3277(g)(2) requires cages or wells on fixed ladders of more than 20 feet, which is stricter than the federal 24-foot trigger under 29 CFR 1910.28(b)(9). Cal/OSHA enforces the California standard in California workplaces. Separately, replacing a fixed ladder or any section of one obligates that section to a fall arrest or ladder safety system at that time, and a ladder cage does not satisfy that on its own. See the full fixed ladder fall protection page.

Our architect designed a rail. Will you just build it?

We will build it, and we will tell you first if we think it will not pass. That happens most often with decorative rail that misses ADA geometry or guardrail infill with openings that are too large. Finding that at shop drawing review costs a phone call. Finding it at inspection costs a rebuild.

Do you handle the plan check comments?

Yes, when we produced the drawings. Responding to plan check, revising, and resubmitting is part of the permit scope rather than something we hand back to you mid-review.

Can you do a compliance survey of our facility?

Yes. The most common version is a fixed-ladder inventory counted against the California 20-foot trigger: count, heights, condition, and photos, producing a budget number you can phase across capital cycles. Our preventative maintenance programs include facility condition assessment and reporting with photographic documentation of deficiencies, which produces the same inventory as part of a scheduled program.

If an inspector has already written it up, send us the correction notice

That document tells us exactly what has to change, which is the fastest possible start.
