As a quality compliance manager in the building materials sector, I've seen procurement cycles drag on for months because teams focused on the wrong specs. This checklist is for project managers, facility directors, and architects who need to evaluate an elevator supplier—KONE or otherwise—and want to avoid the headaches I've seen firsthand. It's based on reviewing specs for over 200 commercial projects annually.

When This Checklist Applies

Use this when you're comparing proposals from major elevator manufacturers for a new commercial building, retrofit, or modernization project. It's designed for the evaluation phase—not for initial RFQs or final contract negotiations. You've got 2-3 proposals on the table. Now what?

Here are the 7 steps I walk through with our teams. Skip step 3 at your own risk. (More on that later.)

Step 1: Verify the Core Technology Fit (Not Just the Spec Sheet)

Everyone reads the speed and capacity specs. That's table stakes. What I look for is the technology platform. For instance, KONE's Ecodisc® system is their core innovation for machine-room-less (MRL) elevators—it uses a permanent magnet synchronous motor directly integrated into the hoistway. But here's the thing: not every MRL system is the same.

What to check:

• Is it truly machine-room-less? Some systems reduce the machine room size but don't eliminate it. KONE's MonoSpace® is genuinely MRL, freeing up roof space or eliminating a penthouse floor. Confirm the footprint.
• What's the energy regeneration capability? Modern drives can feed power back into the building grid. KONE's systems offer this, but verify the percentage. (I've seen specs claim 'regenerative' with a 10% recovery rate, which is barely noticeable.)
• Ask about the brake system: This is a safety-critical element. KONE uses a disc brake design. Ask for the mean time between failures (MTBF) data on the brake assembly—most sales engineers can provide it if pushed.

Honestly, I'm still surprised how often buyers skip this step. They compare 2.5 m/s vs 4 m/s, but don't ask how that speed is achieved. The technology platform determines long-term maintenance costs, upgrade paths, and spare parts availability.

Step 2: Map the Spare Parts Supply Chain

This is where the 'value over price' argument becomes concrete. A supplier might offer a lower upfront cost, but if their spare parts ecosystem is weak, you'll pay for it later.

Checklist items:

• Global vs. local stock: KONE has a global network, but what's the lead time for a replacement door operator in your region? Get a commitment in writing: 5-day standard, 24-hour express.
• Parts compatibility across models: If you're modernizing, can you use parts from the new model on older ones? (This is a common blind spot. A 'full modernization' might replace the controller, making all old parts obsolete.)
• Non-proprietary components: Some manufacturers use custom parts for everything. Others, like KONE with some of their standard controllers, use off-the-shelf components available from multiple distributors. Ask for a list of 'critical parts' and their sourcing.

The most frustrating part: we once specified a specific spare parts list in the RFP, only to find a supplier couldn't guarantee availability beyond 5 years. We had to re-spec, costing us a $22,000 redesign and delaying the project by 6 weeks. So glad we caught it during evaluation, though. Almost signed the contract.

Step 3: Assess the Maintenance Network Structure (The Skipped Step)

Most buyers focus on the equipment and installation price. They completely miss how the maintenance network is structured. Here's the truth: an elevator is only as good as its service provider.

Three questions most people don't ask:

• Are the technicians factory-trained or third-party? KONE uses its own technicians (mostly). Some competitors use authorized dealers who may or may not have the same training. Ask for the certification rate in your region.
• What's the response time guarantee for different faults? Not just '24/7 service.' Layer it: catastrophic failure (car stuck) vs. minor annoyance (door delay). KONE's customer care center tracks this. Get the SLA tiers.
• How does the network handle parts from older models? In our Q1 2024 audit, we found one supplier's network had phased out support for a 12-year-old controller. The building owner was on their own. Ask about the 'end-of-support' timeline for the model you're buying.

People think expensive vendors deliver better service. Actually, vendors who have invested in a dense, trained service network can afford to charge more. The causation runs the other way. The assumption is that service is a commodity. The reality: it's the single biggest differentiator after year 5 of ownership.

Step 4: Request a 'No-Surprise' Cost Model (Total Cost of Ownership)

This aligns directly with my experience. The lowest quote has cost our clients more in 60% of cases I've been involved in.

Ask the supplier to provide a 5-year total cost projection, including:

• Base installation price (confirmed)
• Rigging and hoisting costs (often separate)
• Electrical connection and building modifications (e.g., strengthening the shaft)
• Annual maintenance contract cost (with annual escalations clearly stated)
• Average cost of non-contract repairs (e.g., door adjustments after high-traffic events)
• Estimated spare parts cost for the first 3 years (replace door belts, rollers, etc.)

A concrete example from a project last year: Supplier A's base price was $85,000 vs. Supplier B's $78,000. But Supplier A included a 5-year maintenance cap with a 1.5% annual increase. Supplier B's maintenance was 'at prevailing rates.' Over 5 years, Supplier A was $2,000 cheaper total. (Dodged a bullet on that one.)

Step 5: Inspect the 'Hardware Finish' for Brand Consistency

This might seem minor—it's where my quality inspector background kicks in. The fixtures (door handles, coupe glass, interior panels) are the user-facing elements. They affect perception and maintenance costs.

Check these specifically:

• Door handle durability: Request a sample of the handle material (e.g., stainless steel grade 304 vs. 430). We once had a batch of 50 handles where the coating started peeling after 6 months. The vendor claimed it was 'within industry standard.' Normal tolerance is no visible wear for 2 years. We rejected the batch.
• Coupe glass (if applicable): Is it laminated or tempered? For commercial lobbies, laminated is required for safety. Verify the manufacturer's name and IBC compliance.
• Control panel aesthetics: I ran a blind test with our facilities team—same panel with a brushed vs. glossy finish. 80% identified the matte/brushed finish as 'more professional' for a corporate building without knowing the difference.

This matters because a poor finish on the fixtures makes the entire building feel lower quality. For a premium brand like KONE, this is a core part of their offering. If the handles look cheap, your building's image suffers.

Step 6: Test the 'What If' Scenarios

A good supplier plans for the norm. A great supplier plans for the exception.

Simulate these with the account manager or project manager:

• Power outage: How does the system behave? Does the car descend slowly or just stop? KONE's systems have a 'rescue drive' that uses battery backup to bring the car to the nearest floor. (Ugh, we once had a system that just stopped. Not great, not terrible. Serviceable, but stressful.)
• Fire alarm integration: How does the elevator interface with the building's fire system? Does it recall to the lobby? Does it disable the escalators automatically?
• Peak traffic management: For commercial buildings, what happens at 5 PM on a rainy Friday? Some systems optimize for up-peak (everyone arriving). Few optimize for down-peak efficiently. Ask about 'destination dispatch' capabilities—KONE's solution uses group dispatching algorithms.

The reality: most suppliers have a standard response. The difference is in the detail of their answer. If they say 'we follow code,' that's a warning sign. If they walk you through the step-by-step logic, especially for power loss, their system is likely more robust.

Step 7: Verify Corporate Stability and Global Reach

This is one those points that's easy to overlook when you're focused on the product. You are entering a 20-30 year relationship. The company needs to be around.

What to dig into:

• Recent mergers and corporate structure: KONE's merger with parts of thyssenkrupp's elevator business has created a larger global entity. This usually means a stronger parts supply and R&D budget, but also possible integration hiccups. Ask how the merger has affected their maintenance network in your region.
• Research and development spending: A company that doesn't invest in R&D will leave you with obsolete technology. KONE's investment in energy efficiency (their Ecodisc system) is a long-term benefit to building owners.
• Reference projects of similar size: Don't just ask for any references. Ask for a 20-story office building they've installed in the last 3 years. Call the building manager. The conversation is gold.

Common Mistakes and Final Tips

Before you sign, watch out for these:

• Ignoring the fine print on maintenance contracts: Look for 'automatic renewal' clauses and price escalation caps. (ugh, again—the third late payment from a building owner we client-managed was because they didn't read the renewal terms.)
• Assuming 'standard' features are included: 'Emergency phone' might be standard in some markets but an add-on in others. Clarify every line item.
• Not verifying the installer's credentials: The manufacturer (KONE, in this case) installs in many markets, but they also use authorized dealers. Ensure the installer is certified by the manufacturer for your specific model.

One last thought: This checklist was accurate as of early 2025. The elevator industry changes fast (new codes, new technology, market consolidation). Always verify the specific regulatory standards (e.g., ASME A17.1 in the US, EN 81 in Europe) and current pricing. I learned some of these evaluation criteria in 2020, and the landscape has definitely evolved, especially with the rise of IoT-based predictive maintenance.

Hope this helps streamline your next elevator evaluation. (Finally, a checklist that actually covers the gaps.)
