Hiring guide: Mechanical, Structural & General Craft
Data Center Headhunters recruits critical facilities, data center operations, construction and delivery, commissioning, power and cooling, and executive talent for colocation, hyperscale and enterprise sites. We research the market, contact working people and qualify a shortlist for your opening. No upfront fee. You pay only if you hire.
This family covers the people who build and hold up the physical shell of a data center: pipe, sheet metal, welding, steel, concrete, rigging and general craft, and each of these has its own license rules, test regime and way of being misdescribed on a résumé.
This is what we do all day: recruit data center professionals.
No postings. No stacks of resumes. No chasing. You interview a short list.
No upfront fee. You pay only if you hire.

What does this hire really come down to?
The first decision is whether you are hiring a craft trade or a general role. Craft trades such as pipefitting, welding and sheet metal carry qualifications that are tied to the work: a weld procedure, a pressure code, a pipe material, a jurisdiction. General roles such as laborers and helpers do not, and the question there becomes site reliability.
The second decision is who signs for the work. In mechanical systems, a foreman or superintendent usually directs, an inspector or engineer accepts, and the craftsperson installs to a procedure. In structural and rigging, a qualified person plans the lift and the rigger executes it.
Finally, decide whether the work is new construction or inside a live facility. Fitting pipe in an open shell is not the same as tying in to a loop that carries cooling to running equipment.
What do we check before you see anyone?
For welders, ask which processes, materials and positions they have worked, and whether they hold a current qualification for your procedure. Weld test results can be tied to an employer, so ask how the previous qualification was established. For pipefitters and sheet metal workers, ask for a job walk from takeoff through testing, flushing and cleanliness.

Where do we find these candidates?
Union and open-shop mechanical contractors supply most of the trained pipefitters, welders and sheet metal workers, and their apprenticeship records give you checkable history. Industrial and power-plant maintenance crews offer craftspeople who understand live systems and outage discipline, though they may be new to construction scheduling.
Which hiring mistakes should you avoid?
Do not ask for every trade in one hire and then settling for someone who is average at all of them. Do not assume a pipefitter from industrial work understands cleanliness and commissioning expectations in a cooling loop. Do not use a senior-sounding title, then assigning helper-level work.

How the search runs
Describe the work, then the title
We begin with the systems, materials and inspection regime on your project, and only then agree a title so the search pool is accurate.
Separate crafts and general roles
If you need several seats, we divide them by qualification and supervision so that each has its own screen and honest expectations.
Verify with the issuer
For each qualification a person claims, we check what it covers, who issued it and when, and report what could not be confirmed.
Interview questions
What did you install, what did it carry or support, and how was it tested? A candidate who understands the purpose explains the pressure, load or flow; one who only handled materials lists tools.
What did the last inspector reject, and how was it fixed? A useful answer names the defect, the correction and what changed afterward.
Who checked your work, who could stop you, and who did you report to? The answer shows how the person behaves inside a controlled project, and whether they understand where their authority ends.
What happens when the drawing conflicts with the field? Experienced craftspeople stop and raise it with the person who owns the answer instead of building what looks close.
Search mechanics that help you
Give us the procedure, material and inspection regime before you describe the person.
Questions
How long does it take to find welders qualified to a specific procedure?
It varies with the trade, how specific your procedure requirements are and whether you need people for a live building. Welders with specific qualifications take longer than general helpers. We will tell you after the scope call where the difficulty lies, without promising a date.
Can a foreman's on-the-spot raise keep a qualified fitter from leaving?
They often get them, since a foreman can make an offer on the spot to keep a qualified welder or fitter. We ask early about the reasons for looking and about whether the current employer already knows. Reasons tied to travel or growth usually survive a counteroffer less well than pay disputes.
Will pipefitters and ironworkers move for a multi-year program?
Many follow work and expect lodging rather than permanent moves. Fewer will relocate with family, and typically only for long programs. Tell us the length of the project and the housing you can support.
Should every trade on a crew receive the same per diem terms?
Decide on one policy for the whole crew so that a welder and a fitter are not comparing different terms on site. State whether per diem is paid on days worked or days away, and what lodging is covered. Differences between trades breed resentment quickly.
How do we test whether a fitter will hand off cleanly to the welder and inspector?
Judge each against the work it will perform, then ask how it hands off to the next trade. A fitter who understands what the welder and the inspector need is easier to place than a strong one who works alone. Group interviews with the foreman often reveal this quickly.
Does hiring four trades in one search change how terms are discussed?
Fee terms are set per search and agreed in writing before work begins. If you want several seats, tell us at the start so we can discuss them together rather than separately. We will explain terms plainly before you commit.
