The Eleven Percent: Soph Davenberry, Sheet Metal Worker

Eleven percent sounds like a tip you leave when you’re mad at the service. In construction, it’s closer to a mirror: depending on the dataset and the job category, women make up roughly about eleven percent of the U.S. construction workforceand a much smaller slice of the hands-on trades on many sites. That gap isn’t just a statistic. It’s a daily experience: who gets assumed to be “the helper,” who gets mistaken for “the admin,” and who has to proveagainthat they belong on the lift, in the shop, and in the meeting where the real decisions happen.

This is where Soph Davenberry comes in. Soph is a union sheet metal worker whose career threads through apprenticeships, HVAC, and the wonderfully nerdy corner of the industry known as Testing, Adjusting, and Balancing (TAB). If you’ve ever stood under a vent thinking, “Why is this room either a sauna or a meat locker?” TAB is one of the reasons you don’t have to live that way.

So yesthis is a story about a person. But it’s also a field guide to a trade that’s hiding in plain sight: the sheet metal work that shapes the air you breathe, the comfort you feel, and the performance your building was promised on paper.

Why “The Eleven Percent” Matters (and Why It’s Not Just About Optics)

When an industry is short on skilled labor, every barrier becomes expensive. Not just “we can’t hire fast enough” expensivemore like “projects slip, costs climb, and everyone argues in fluorescent-lit trailers” expensive.

Bringing more women into construction isn’t charity. It’s capacity. More apprentices in the pipeline. More experienced journeyworkers staying in the field. More forepersons, estimators, TAB technicians, and commissioning specialists who can keep complex buildings running the way engineers and owners expect.

And the buildings are only getting more complex. High-efficiency HVAC systems, tighter envelopes, advanced controls, indoor air quality requirements, smoke control testingtoday’s jobsite is part metal shop, part data lab. The talent pool can’t stay stuck in “half the population need not apply.”

That’s the quiet punchline of “the eleven percent”: it’s a reminder that the work is too importantand too technicalfor the workforce to be that narrow.

Meet Soph Davenberry: From Apprentice to Building-Performance Pro

Soph’s path doesn’t read like a straight line so much as a well-built duct run: it bends where it needs to, stays supported, and ends up exactly where it’s supposed to go.

Here are a few concrete landmarks that show what a long-term career in the sheet metal trades can look like:

• Started in the sheet metal trade as an apprentice in 1996, then began focusing on TAB in 2004specializing in the final tuning that makes systems work as designed.
• Worked in building-performance roles including TAB management and systems field engineeringjobs that require a blend of field craftsmanship, measurement discipline, and a deep understanding of mechanical systems.
• Joined NEMIC as Chief Technology Officer in early 2019, connecting workforce development and emerging opportunities across the union sheet metal ecosystem.
• Recognized in the HVAC industry as one of Engineered Systems Magazine’s “20 Women to Watch,” highlighting leadership across roles ranging from entry level to ownership.

But the most “Soph” moment might be the one that’s not about a title at all. When asked for advice to prospective women engineers, Soph flipped the framing. In a few sentences, they called out the weirdness of labels like “female engineer” and offered a better focus: the work itself and the respect that should come with professionalism.

Two short lines capture the stance without any extra decoration: I am a sheet metal worker. I am an engineer.

That perspective matters because sheet metal workespecially TABsits right on the seam between trades and engineering. It’s hands-on, tool-driven, physical work. It’s also measurement, documentation, and systems thinking. Soph’s career proves you don’t have to pick one identity and shrink yourself to fit it.

What Does a Sheet Metal Worker Actually Do?

If “sheet metal worker” makes you picture someone wrestling a single, sad rectangle of tin in a dim garage… you’re not totally wrong, but you’re missing the good parts. In modern commercial construction, sheet metal workers commonly fabricate and install HVAC ductwork and related components that move air through hospitals, offices, schools, data centers, and everything in between.

The core work (aka the part nobody notices until it’s wrong)

• Fabrication: Measuring, cutting, shaping, and assembling metal componentsoften with computer-guided equipment in a shop, then finishing details in the field.
• Installation: Hanging duct, setting equipment connections, sealing joints, and coordinating with other trades so your duct run doesn’t “mysteriously” intersect a sprinkler main.
• Service and retrofit: Updating older buildings for energy performance, ventilation needs, or new tenant layoutswhere nothing is square and every ceiling tile hides a surprise.
• Specialty work: Architectural sheet metal, smoke control systems, industrial ventilation, and other niches that require additional expertise and certification.

Sheet metal is also a trade with a clear ladder. Many people start in the shop or on installs, then move into roles like foreperson, detailer, estimator, project manager, or (in Soph’s world) building-performance specialization.

Why TAB Is the “Final Boss” of HVAC (In a Good Way)

TABTesting, Adjusting, and Balancingis what turns an HVAC system from “assembled” into “actually performs.” Think of it like tuning a guitar. You can bolt strings onto wood all day long. But until you tune it, it’s just a confidence problem with a soundtrack.

A TAB technician measures airflow, pressure, temperatures, and other system outputs, then adjusts dampers, fan speeds, and control settings so each space receives the ventilation and comfort it was designed for. It’s the difference between:

• a classroom where half the students are sweating and half are freezing,
• an operating room that can’t maintain pressure relationships,
• a lab exhaust that doesn’t pull what it’s supposed to pull,
• and an office floor where the “hot complaint” travels faster than the Wi-Fi.

At one point in Soph’s career, they were described as an expert in smoke control, specialty test equipment, and systems assessmentsareas where measurement discipline and method matter. Smoke control, for example, is not a vibes-based activity. You test it, document it, and verify that the system does what it says on the drawings.

And here’s the thing: TAB is a perfect example of why “trade work” and “technical work” aren’t opposites. TAB demands field awareness, math, documentation, and the ability to troubleshoot across equipment, duct, controls, and human expectations (the hardest subsystem of all).

The Training Path: Apprenticeships, Union Pipelines, and Paid Learning

Many sheet metal workers enter through apprenticeship programs that combine paid on-the-job learning with classroom instruction. It’s one of the most straightforward “earn while you learn” models in the U.S. workforce.

Union programs in the sheet metal world are often connected to national training infrastructure that supports both workers and signatory contractors. In plain English: you get structured training, safety expectations, clear wage progression, and portable skills that travel with you.

What you learn (besides how to find your tape measure after it teleports)

• Blueprint reading and layout
• Shop math and geometry (yes, it matters, and yes, your phone calculator is allowed to help)
• Fabrication methods and installation practices
• Rigging basics and jobsite coordination
• Airflow fundamentals, system components, and troubleshooting
• Safety practices that keep you working for decades instead of “until Tuesday”

Specializations like TAB can come later, when a worker wants to lean into measurement, diagnostics, commissioning support, and building performance.

Safety: The Sharp, Loud, Occasionally Smoky Reality

Sheet metal work is rewarding, but it is not gentle. The materials can be razor-edged. The environments can be loud. And depending on the taskcutting, grinding, welding, working in mechanical roomsyou may deal with fumes, particulates, and confined spaces.

So let’s say this plainly: safety is not a slogan. It’s a system.

Common hazards (and how pros think about them)

• Lacerations and punctures: Metal edges don’t care about your feelings. Proper gloves, handling techniques, and planning your cuts matter.
• Eye and face injury: Cutting and grinding can throw debris. Eye protection is non-negotiable.
• Noise exposure: Shops and sites can be loud enough to do long-term damage. Hearing protection is a career investment.
• Falls: Lifts, ladders, scaffoldsHVAC and ductwork live overhead, and gravity stays undefeated.
• Welding fumes: If you’re welding or near welding, ventilation and fume control matter. Guidance often emphasizes local exhaust ventilation and positioning to keep fumes out of the breathing zone, and notes that confined spaces can greatly increase risk.

The goal isn’t to be fearless. The goal is to be deliberate: assess hazards, choose the right protective equipment, use ventilation controls where needed, and build the habit of stopping work when something isn’t right.

Sheet Metal Work in 2026 and Beyond: Prefab, BIM, and the “Healthy Building” Era

The stereotype of construction as “old-school” collapses the moment you step into a modern sheet metal shop. More work is being prefabricated to improve quality and reduce waste. Digital modeling (like BIM) helps teams coordinate tight mechanical spaces before anyone cuts metal. And as buildings push for efficiency and healthier indoor environments, ventilation becomes a frontline systemnot an afterthought.

This is where Soph’s blend of trade background and building-science education becomes especially relevant. Their career sits in the overlap between:

• Craft: knowing how systems get built in the real world
• Performance: verifying that systems deliver what the design promised
• Sustainability: improving energy outcomes without sacrificing occupant comfort or air quality

One example of systems thinking showing up in real life: Soph’s academic work was noted for aligning coursework with community impactlike helping a local church improve energy efficiency and advising on sustainable operations. That’s not “extra.” That’s the direction the industry is heading: performance, verification, and long-term outcomes.

Changing the Demographics: What Helps (and What Absolutely Does Not)

If you want more than eleven percent, you don’t get there by posting a single stock photo of a woman in a pristine hard hat and calling it a day. You get there by changing conditions that make people leave: culture, training access, jobsite respect, and clear pathways to advancement.

Soph put it bluntly in a workplace context: respect has to function across boundariesjobsite culture and office culture can differ, but professionalism should hold on both sides of the safety barricades.

Practical steps that move the needle

• Early exposure: shop class, pre-apprenticeships, and “try-a-trade” experiences that treat the trades as skilled careers, not backup plans.
• Mentorship that’s real: not performative, not occasionalactual support from people who know the work.
• Clear expectations: defined training standards, predictable wage progression, and feedback that’s tied to performance.
• Workplace respect: fewer “jokes” that are really just gatekeeping in a funny hat.
• Supportive programs: initiatives that expand access to apprenticeships and nontraditional occupations, especially for groups historically excluded.

Or, as Soph’s advice implies: focus on doing the work, find peers, keep asking questions, and model the respect you expect to receive. That’s not motivational-poster talk. That’s survival strategyand it’s how people build long careers.

Conclusion: The Eleven Percent Is Not a Ceiling

Soph Davenberry’s career shows what’s possible when a worker gets access to training, specialty pathways, and a professional culture that recognizes skill. From apprentice to TAB specialist to industry leadership, the throughline isn’t luck. It’s competence, consistency, and a refusal to accept limiting labels.

Sheet metal work is physical, technical, and essential. It’s also evolving fasttoward better performance, cleaner indoor air, and more accountable building outcomes. The industry needs more people who can do the work and lead the work.

Eleven percent is a snapshot, not a destiny. If the trade wants to thrive, it has to widen the doorand keep it open long enough for people to build careers, not just survive a season.

Field Notes: 500+ Words of Real-World Experience Around “The Eleven Percent”

This last section is a boots-on-the-ground look at the kinds of experiences that commonly come with sheet metal work and TABespecially for someone navigating a jobsite culture where “eleven percent” can feel like “one person on this floor.” These moments are not meant to quote Soph directly; they’re the kind of patterns and lessons that show up repeatedly in trade careers like theirs.

1) The first day: learning the language (and the pace)

You show up early, because showing up early is the first skill. Someone hands you materials with names that sound like they were invented to confuse apprentices on purpose: slip, drive, S-cleat, turning vanes. The pace is brisk, not because people are unkind, but because the schedule is real. The quickest way to earn trust is to stay curious, move with intention, and ask questions that show you’re paying attention: “Where do you want this staged?” beats “What do I do?” every time.

2) The invisible math behind the visible metal

Sheet metal work is geometry you can carry. A duct transition looks simple until you have to build it so it fits, seals, and doesn’t fight the ceiling grid. Over time you realize the trade rewards people who can visualize space, read drawings, and think in dimensions. Your hands do the work, but your brain is the real foreperson.

3) TAB day: when the building tells the truth

TAB is where “it should work” meets “does it work.” You log readings, compare them to design intent, and start chasing down why a zone is starving for air. Is a damper stuck? Is a VAV box mis-set? Is a duct run pinched by someone else’s last-minute change? When you fix it, the win isn’t applause. The win is the building becoming calmtemperatures stabilize, complaints drop, and the system starts behaving like it read the manual.

4) Smoke control and specialty testing: calm under pressure

Specialty testing requires a different mindset. You don’t rush; you verify. You document carefully, because your results matter to life safety systems and the teams who sign off on occupancy. The best technicians develop an almost boring consistency: same setup, same procedure, same rigor, every time. “Boring” is a compliment when the stakes are high.

5) Culture: the difference between “fitting in” and being respected

On some sites, the culture is professional; on others, it’s a time capsule. If you’re one of the only women (or one of the only people who doesn’t match the jobsite stereotype), you learn quickly that respect is built in layers: competence, consistency, and boundaries. You don’t have to laugh at every joke. You don’t have to explain your identity to do your job. And you do have the right to expect a baseline of professional behaviorbecause safety, quality, and teamwork depend on it.

6) Community and belonging: finding your people

One of the most practical career moves is building a network: other tradespeople, industry groups, mentors, and peers who can answer questions without judgment. That community might come from a union local, a training center, a pre-apprenticeship program, or a professional circle in building performance. When the work gets hardand it willbelonging is part of what keeps people in the industry long enough to become experts.

7) The long view: connecting trade skill to sustainability

Eventually, many sheet metal workers start seeing buildings as systems, not just jobs. Airflow affects comfort, health, and energy. Measurement and commissioning help owners get what they paid for. The “eleven percent” conversation isn’t separate from that; it’s intertwined. When more people can enter and stay, the industry gets stronger at every levelfrom the duct you can see to the performance you can measure.
