If you're specifying an elevator for a mid-rise commercial project and you're not using a pre-purchase checklist, you're gambling. I know this because in September 2022, I gambled on a $3,200 order for a single car—and lost.
This guide is for facility managers, architects, or anyone who writes specs for vertical transportation systems. It's not about theory. It's the exact 5-step checklist we use now, born from a mistake that cost roughly $12,000—including redo, delay penalties, and credibility.
Here are the 5 steps. Do them in order. Skip one at your own risk.
Step 1: Define 'Standard' in Writing—Not Assumption
In my first year handling elevator specs, I made the classic rookie error: assumed 'standard' meant the same thing to every vendor. I approved a spec that said 'Standard cab interior, Otis Gen2.' The vendor delivered a basic laminate finish that looked nothing like the showroom model I had in mind.
What to do instead: Write down every measurable attribute. Cab dimensions, finish materials, door opening width, control panel layout. Get it into a spec sheet that both you and the vendor sign off on. Use the Otis parts catalog as a baseline reference—their model numbers and options are standardized for a reason.
Here's a quick comparison to keep it tangible: According to USPS (usps.com), a standard letter envelope is defined by specific dimensions (3.5" x 5" minimum to 6.125" x 11.5" maximum). If you just say 'standard envelope' without those numbers, you might end up with a postcard when you needed a legal document mailer. Same with elevator specs—'standard' is meaningless without the details.
Step 2: Verify the Load Capacity—Not Just the Nameplate
This is the step that most people skip. It's tempting to look at the nameplate rating (say, 2,500 lbs) and move on. Don't. The real-world capacity is affected by cab configuration, door dimensions, and motor settings.
I once ordered an Otis Gen2 for a medical office building, assuming the standard 2,500 lbs would handle hospital beds. It didn't. The cab width was fine, but the door opening was 1-inch narrower than the minimum for bed passage. The unit passed inspection, but it was functionally useless for the client's primary use case.
What to do: Request a load test simulation from the vendor. Ask for the specific motor configuration and confirm it matches your expected usage pattern. Don't just trust the brochure—ask for a submittal drawing that shows the actual dimensions, not just the model number.
Step 3: Clarify 'Standard' Delivery and Installation Timeline
Another common pitfall: assuming the quoted delivery timeline includes installation. It often doesn't. The timeline you see on the initial quote is usually door-to-dock, not door-to-operation.
We learned this the hard way on a project in Q1 2024. The vendor quoted 8 weeks for an Otis elevator system. I assumed that meant ready to use. It meant the equipment arrived at the site in 8 weeks. Installation took another 4 weeks. That 4-week gap cost us $2,800 in delay penalties from the general contractor.
What to do: In the spec, separate 'delivery' from 'commissioning.' Write it out: 'This specification includes delivery within 8 weeks from order, and full installation and testing within 5 weeks from delivery.' Then get written confirmation that this is included in the price.
Step 4: Specify the Service Agreement Upfront
This is a big one that new buyers forget entirely. An elevator is not a toaster. It requires ongoing maintenance. The price you negotiate for the equipment should be paired with a clear service agreement—not as an afterthought, but as part of the specification.
I made this mistake in 2023. We bought a beautiful Otis Gen3 for a commercial building. Three months after installation, the door sensors malfunctioned. No service plan in place. The repair cost $1,200 out of pocket. Had we specified a 2-year service contract in the purchase order, it would have been covered.
What to do: Before signing the PO, request the service agreement terms. Ideally, get 12 months of labor and parts included. If not, negotiate a pre-paid price for the first year. Write it into the spec: 'Price includes 1 year of preventive maintenance and on-call repair labor.'
Step 5: Include a 'Proof of Performance' Clause
Here's the pro move that came from our biggest mistake. After the 2022 incident, I added a clause to every spec that reads: 'Final payment is conditional upon proof of performance, including a witnessed load test and visual inspection of finish quality matching the approved sample.'
This isn't about being mean to the vendor—it's about having a clear, objective acceptance criteria. Without it, you're relying on trust alone. With it, you have a documented standard that both sides agree to before the work starts.
What to do: Add this to your spec language: 'Vendor shall provide 48-hour notice of final testing. Buyer or buyer's representative shall be present to witness and approve the test. Any deviations from approved specs shall be corrected at vendor's cost before final payment.'
Final Checklist (Print This)
- Written spec with measurable attributes (don't assume 'standard').
- Verified load capacity with door dimensions—not just nameplate.
- Separate delivery and installation timelines written into the contract.
- Service agreement included in the purchase order, not added later.
- Proof of performance clause requiring witnessed testing before final payment.
A Note on Budget and Expectations
One last thing: pricing. According to major online printer quotes (January 2025), business cards cost $25-60 for 500. That's a fixed, well-known price. Elevators are not like that. Prices vary wildly based on specs, region, and negotiation.
What I can tell you is: budget 10-15% more than the first quote for 'unexpecteds.' In our case, the $3,200 spec error turned into $12,000 real cost because we didn't verify the details. That extra margin would have covered the mistake entirely.
