How to Evaluate Elevator Components Manufacturers: A $14,400 Mistake and the Checklist That Saved Us
September 2022: The call that started it
It was 7:42 a.m. on a Tuesday in September 2022. The general contractor on a 12-story hotel modernization didn't say hello. He said, "The elevator inspector just left. We have a problem."
I've been handling elevator modernization and architectural metal orders for eight years. I've personally made—and documented—11 significant mistakes, totaling roughly $23,000 in wasted budget. Now I maintain our team's pre-award checklist. But back then, I was still learning the hard way.
We needed replacement elevator components: door operators, car panels, guide rails, and a small package of architectural metal—galvanized bar grating platforms, mesh infill, and a glass railing section for the lobby. The schedule was tight. Six weeks from PO to installation. Not impossible, but not generous.
How I picked the wrong vendor
I sent the spec package to three elevator components manufacturers. Two came back with detailed submittals, material certificates, and lead times that matched the schedule. The third came back 18% lower and promised four-week delivery. Their quote looked clean. Their samples looked fine.
People think low price causes missing documentation. Actually, missing documentation often causes the low price—or at least enables it. A manufacturer that doesn't track heat numbers, doesn't pay for third-party inspection, and doesn't maintain a formal QA process can quote lower because they're not absorbing those costs. The causation runs the other way.
I approved the low bid. Even after choosing them, I kept second-guessing. What if their quality wasn't as good as the samples? What if the four-week promise was based on hope, not capacity? The three weeks until the first shipment were stressful.
The delivery that went wrong
The shipment arrived on a Friday. By Monday, we knew.
The door operator mounting brackets were drilled 3/8 inch off-center. The car panel steel wasn't the specified ASTM A992 grade—it was generic A36 with no mill test report. The guide rail clips were fine, but the galvanized grating had bare welds with no ASTM A123 zinc coating. The glass railing brackets didn't match the embed plates already cast into the lobby slab.
Then the real problem: the vendor had outsourced the door operators to a second shop. That shop had never seen our approved drawings.
We stopped installation. The elevator inspector wrote up the nonconformance. The GC called twice a day. The hotel owner started asking about liquidated damages.
If I remember correctly, the redo cost was $14,200—no, $14,400, I'm mixing it up with the freight penalty. Either way, it was a $14,000 mistake. Plus a three-week delay. Plus overtime for the install crew. Plus the kind of credibility damage you don't put on a balance sheet.
What I should have done differently
Looking back, I should have paid for a third-party pre-shipment inspection. At the time, the standard delivery window seemed safe. It wasn't.
I also should have required documented compliance before awarding the PO, not after. The two other vendors included that documentation without being asked. That was a signal I ignored.
Honestly, I'm not sure why some vendors treat mill certs and first-article inspections as optional. My best guess is that it comes down to internal documentation culture. Some shops build the paperwork into production. Others treat it as an afterthought.
The seven-point checklist we use now
After the third rejection in Q1 2024, I created our pre-check list. We've caught 47 potential errors using it in the past 18 months. It's not glamorous. It works.
- Standards and certifications. For elevator components, ASME A17.1/CSA B44 is the baseline in North America. ISO 8100-1 is common internationally. Ask for the manufacturer's certificate of compliance and the AHJ acceptance history. Don't accept "we build to code" without paperwork.
- Material traceability. Require mill test reports traceable to heat numbers. For steel, confirm ASTM A36, A992, or the grade specified. For galvanizing, ASTM A123 or A153. No mill cert, no approval.
- Dimensional validation. Ask for a first-article inspection report against your approved CAD. For elevator door operators and guide rails, tolerance matters more than marketing.
- Finishing and corrosion control. Coating thickness, salt-spray test data, and galvanized coating weight should be documented. This applies to grating, wire mesh, perforated panels, and any exterior metal.
- Interface compatibility. Elevator components don't work in isolation. Door operators, car panels, rails, and glass railing hardware have to match existing embeds and structural steel. Require interface drawings.
- Production capacity and lead time. A quoted lead time without a capacity review is a guess. Ask who is actually making each component and whether any work is subcontracted.
- Documentation and change control. Submittal logs, RFI responses, revision numbers. If they can't track a revision, they can't track your order.
Where this applies beyond elevators
The same logic applies when you're vetting a metal siding supplier or a glass railing manufacturer. The product changes. The questions don't. Can they prove material origin? Can they hold a tolerance? Can they document a change?
We also started using mcnichols steel as a benchmark for architectural metal packages. Not because they're the only option, but because their spec sheets and mill certs were consistent. We've used mcnichols eco mesh as fallback protection infill on hoistway access platforms. The point isn't the brand. The point is that a supplier who makes documentation easy is usually a supplier who makes production predictable.
That's the efficiency lesson I keep coming back to. Efficiency isn't just speed. It's fewer surprises. Switching to a shared pre-award checklist cut our quote review from five days to two. The automated document tracker eliminated the data-entry errors we used to have. But the checklist only works because someone still reads the mill certs and calls the fabricator. Traditional review still matters.
What I tell new buyers now
If you're evaluating elevator components manufacturers, don't start with price. Start with documents. Ask for the last three projects they supplied with similar components. Ask for the mill certs on those projects. Ask what happened when a shipment failed inspection.
The vendor who answers those questions quickly is the one you want. The vendor who says "we'll send it after the PO" is the one who cost me $14,000.
That mistake was mine. The checklist is how I make sure it's not yours.
