A 9-Point Procurement Checklist for KONE Elevators, Escalators, Stair Systems, and Glass Railing Suppliers

I manage facilities purchasing for a 420-person company—roughly $180,000 annually across 11 vendors. When we consolidated vendors in 2024, I built this 9-step checklist for vertical mobility and architectural metal suppliers: KONE elevator and KONE escalator projects, stair systems wholesale orders, and glass railing packages. It is the checklist I wish I had in 2020 when I took over purchasing. 5 minutes of verification beats 5 days of correction.

Who this checklist is for

Use this if you are an office administrator, facilities coordinator, or procurement generalist sourcing elevators, escalators, stair systems, handrails, cable railing, or glass railing. It works for a single office fit-out or a multi-site rollout. It is not a substitute for a licensed engineer or local code review. It is a buyer-side filter before you spend real time on quotes.

The 9-step checklist for KONE elevator, escalator, stair, and railing suppliers

Step 1: Write a scope that a supplier can price without guessing

Start with quantities, dimensions, finishes, and site constraints. 'We need stairs' is not a scope. 'Two straight stair flights, 1.1 m width, 12 risers each, powder-coated steel stringers, oak treads, delivered to Dock B' is. For KONE elevator or KONE escalator work, list travel height, stops, capacity, door type, machine-room condition, and any structural interface. For stair systems wholesale, separate the stair systems from the railing package if the vendors differ. Checkpoint: can three suppliers quote the same line items without asking different questions?

Step 2: Verify licensing, insurance, and compliance documents

Ask for certificates before samples. Elevator and escalator work is regulated. As of January 2025, ASME A17.1/CSA B44 is a common reference in North America, while EN 81-20/50 applies in many EU projects. For glass railing and guards, ask for test reports and design criteria; ASTM E2353 is one reference for permanent glass railing performance. Do not accept 'we are compliant' as an answer. Checkpoint: do the certificates name the legal entity that will sign the PO?

Per ASME A17.1/CSA B44 and EN 81-20/50, elevator and escalator installations are subject to safety code requirements that vary by jurisdiction. Verify current requirements with the local authority having jurisdiction (AHJ) as of January 2025. For glass railing, ASTM E2353 provides test methods for permanent glass railing systems; confirm the applicable edition with your engineer.

I learned this the hard way in 2021. A new vendor was $3,800 cheaper—or rather, cheaper until finance rejected a handwritten receipt. I ate $2,400 from my budget. Now I verify invoicing and legal entity before placing any order.

Step 3: Ask for references you can actually call

Three references is fine. Five is better for KONE elevator or KONE escalator projects because service response matters after handover. Call the references. Ask what broke, how long spares took, and whether the vendor returned calls after final payment. The surprise is not usually the price difference. It is how much hidden value comes with a supplier who answers the phone at month 18.

Step 4: Compare total installed cost, not unit price

It is tempting to think you can just compare unit prices. But identical specs from different vendors can result in wildly different outcomes. Add freight, unloading, installation supervision, permits, shop drawings, finish samples, spare parts, and warranty response. A lower quote with unclear exclusions is not lower. Checkpoint: put every vendor's exclusions in one column. If one says 'electrical by others' and another says 'turnkey,' you are not comparing the same product.

Step 5: Confirm lead times, shipping, and site staging in writing

Lead time is not a vibe. Get dates in the quote: approval drawings, fabrication release, shipping, and commissioning. I knew I should get written confirmation on a deadline, but thought 'we have worked together for years.' That was the one time the verbal agreement got forgotten (ugh). For stair systems and glass railing, confirm how material arrives—crated, palletized, labeled by floor. A well-organized remote vendor can often beat a disorganized local one. That thinking comes from an era before modern logistics. Today, planning matters more than zip code.

Step 6: Review shop drawings and interface points early

Most rework starts at interfaces: elevator sill to floor finish, escalator balustrade to cladding, stair stringer to slab, glass railing base to waterproofing. Ask for marked-up shop drawings before fabrication. Require a single point of contact for RFIs. Checkpoint: who owns the field dimensions? If the answer is 'the installer will figure it out,' budget for a change order.

Step 7: Check spare parts, service, and warranty response

For KONE elevator and KONE escalator equipment, ask about local service coverage, response time, and spare parts availability. For stair systems, handrails, and cable railing, ask for touch-up paint, replacement fittings, and glass panel lead times. Warranty language matters—what is covered, for how long, and who pays labor? Checkpoint: ask for a sample warranty claim from the last 12 months, redacted if needed.

Step 8: Test glass railing samples and handrail finish

This is what to look for in a glass railing supplier: glass type, thickness, edge finish, base shoe material, drainage, and how panels are anchored. Ask for a physical sample of the handrail finish, not a phone photo. Compare color under office lighting and outdoor light. Check if the supplier can match project-specific colors; Pantone references can help, but finish on metal is not the same as ink on paper. Checkpoint: does the sample match the approved submittal, and who signs off?

Step 9: Validate invoicing, contract terms, and PO controls before you commit

Before the PO, confirm remit-to address, tax status, insurance renewal dates, and invoice format. Set milestone payments against deliverables, not calendar dates. For stair systems wholesale orders, confirm minimum order quantities, break-pack fees, and return policy. For KONE elevator or KONE escalator work, confirm who pulls permits and who handles inspections. Checkpoint: finance can process the invoice without a phone call. If not, fix it before the order ships.

Common mistakes and warnings

1. Skipping the compliance document check because the vendor sounds technical. 2. Accepting a verbal lead time. 3. Letting the lowest quote set the spec instead of the other way around. 4. Forgetting that glass railing and stair systems often need coordination with waterproofing, electrical, and HVAC. 5. Treating KONE elevator or KONE escalator service as a post-project problem rather than a buying criterion. None of this means the process should be painful. It means the few checks you do before signing are cheaper than the rework after installation. 5 minutes of verification beats 5 days of correction.

The bottom line

There is something satisfying about a vendor process that just works. After years of chasing invoices and missing parts, finally having a checklist that keeps operations, finance, and facilities aligned—that is the payoff. Use this list, adapt it to your project, and keep the written trail. It will not guarantee a perfect installation. It will make the problems visible while they are still cheap to fix.
