What to Verify Before the Elevator Company Walks Away
When a new installation or modernization wraps up, the contractor demobilizes quickly and your leverage drops with them. The documents, drawings, warranties, and training you collect at turnover determine how easy and how expensive the elevator is to own for the next twenty years. Use this checklist before final payment, while you still have leverage.
Turnover is a one time window, so use it
Turnover is the moment installation or modernization is complete, the elevator passes its final acceptance inspection, and ownership of the equipment transfers to you. It feels like the finish line, but it is really the start of the ownership phase. Everything you fail to collect now becomes harder to get once the crew is gone and the next job has their attention.
The single most effective move is simple: do not release final payment or retainage until the closeout package is complete and verified. That is your leverage, and it disappears the day you sign off. Everything below should be in your hands and checked against the contract before that final check goes out.
Missing paperwork costs you for years
A clean turnover package protects three things: cost, safety, and continuity of service. Without accurate as-builts and model information, future troubleshooting is slower and more expensive, and competitive maintenance bids are harder to get. Without documented warranty terms, you pay for repairs that should have been covered. Without emergency procedures and training, a routine entrapment can escalate.
It also matters for switching providers. If you ever want to put maintenance out to bid or move from the OEM to an independent, the new contractor needs the drawings, manuals, and equipment inventory to price the work and service it safely. A thin turnover package quietly locks you in.
What to have in hand before final sign off
Verify every item below is delivered, complete, and matches the equipment that was actually installed. Get everything in a format you own outright, both printed and digital where possible.
Final inspection documentation
The signed final acceptance inspection from the authority having jurisdiction (AHJ), the current operating permit or certificate, and any related inspection sign offs. This is your proof the elevator is legally cleared for use, and you will need it for the file and for future inspectors.
Acceptance test reports
Documented results of the acceptance tests, including the full load and safety tests (such as the Category 1 / Category 5 load test, governor and safety tests, and speed verification). Keep these as the baseline for future periodic testing and to confirm the equipment performed to spec at handover.
As-built wiring diagrams
The marked up drawings that reflect what was actually installed, not just the generic factory prints. Field changes made during installation must be captured here. Whoever troubleshoots the elevator next depends on these, and on proprietary controllers they are nearly irreplaceable.
Maintenance manuals
Operation, adjustment, and maintenance manuals for the controller, drive, door operator, machine, and major components, along with recommended maintenance intervals. Get them in a format you actually own (printed and/or digital), not a temporary login that disappears.
Warranty information
Warranty start date, duration, and scope (parts only vs. parts and labor), plus any extended terms on major components and the claim process. Confirm the start date in writing, because warranties typically begin at substantial completion or acceptance and the months can slip away unnoticed.
Emergency procedures
Written entrapment and emergency response procedures, firefighters' service (Phase I and Phase II) operation, manual lowering or brake release procedures where applicable, key locations, and the emergency contact and dispatch number for the maintenance provider.
Equipment inventory and model information
A written inventory of make, model, and serial numbers for the controller, drive, machine, door operator, and other major components, plus capacity, speed, and configuration. This is what lets you source parts, request quotes, and judge obsolescence years from now.
Building staff training
Documentation is only half of turnover. Before the contractor leaves, have them walk your building staff through how the elevator behaves and what to do when something goes wrong. This is often the first thing dropped when a job runs late, and the easiest to recover if you ask for it up front.
What staff training should cover
- Safe entrapment response and who to call (never attempt unsafe rescues)
- Firefighters' service: Phase I recall and Phase II in-car operation
- Location of the main line disconnect and machine room access
- How to take a unit out of service safely and report a fault
- Reading basic fault indicators and what info to give dispatch
- Routine housekeeping that keeps the equipment within warranty
What to do when something wasn't handed over
If you discover gaps, act quickly and in writing. The contract almost always requires this material as part of closeout, so you are enforcing an existing obligation, not asking for a favor.
Check the contract scope
Find the closeout, as-built, warranty, and training requirements. These are your reference for what was owed.
Send a written punch list
Itemize exactly what is missing and reference the contract clause. Set a clear delivery deadline.
Hold retainage
If final payment or retainage is still open, withhold it until the closeout package is complete and verified.
Escalate through the warranty
If money is already released, use the warranty relationship and document every request in case of a dispute.
Best practice: Run this checklist before you release final payment. Once retainage is gone, so is most of your leverage to get the rest of the package delivered.
Frequently asked questions
What is an elevator turnover?
Turnover is the point at which the elevator contractor finishes installation (or modernization), the unit passes its final acceptance inspection, and responsibility for the equipment transfers to the building owner. Once turnover happens and the crew demobilizes, getting the contractor back to hand over missing documents, drawings, or training can be slow and sometimes costly. The time to collect everything is before they walk away.
Who is responsible for providing turnover documentation?
The installing contractor is responsible for delivering the closeout package, but the owner is responsible for demanding it. Most installation and modernization contracts already require as-built drawings, manuals, warranty documents, and acceptance test results as part of the scope. If you do not ask for them at turnover, they often never get delivered, and the obligation quietly expires.
Why do as-built wiring diagrams matter so much?
Whoever maintains the elevator next, whether the OEM, an independent, or your own staff for basic items, relies on accurate wiring diagrams to troubleshoot. Field modifications made during installation are frequently not reflected in the generic factory prints. Without the marked up as-builts that show what was actually installed, future diagnosis takes longer and costs more, and on proprietary controllers it can be nearly impossible.
What warranty information should I collect at turnover?
Get the warranty start date, duration, and exactly what is covered (parts only, parts and labor, or specific major components), plus the claim process and contact. Warranties on new and modernized elevators commonly run one to two years, and some major components carry longer terms. The clock usually starts at substantial completion or acceptance, so confirm the date in writing or you may lose months of coverage.
What happens if the contractor already left without handing everything over?
Start with the contract and the closeout requirements, then send a written punch list of the missing items referencing those obligations. Withholding final retainage until the closeout package is complete is the strongest leverage, which is exactly why this checklist should be verified before final payment. If retainage is already released, you are relying on goodwill and the warranty relationship.
Do I need staff training if I have a maintenance contract?
Yes. A maintenance contract covers the equipment, but your building staff still handle day to day situations: responding to an entrapment safely, using the firefighters' service (Phase I and Phase II) keys, locating the main line disconnect, and knowing who to call. Basic operational and emergency training at turnover protects occupants and keeps minor incidents from becoming emergencies.
