Digital elevator inspection

Statutory lift inspections that survive an audit

We build inspection platforms for companies responsible for lifts and lifting equipment across a portfolio of buildings. Scheduled examinations, defect to repair tracking, and certificates a regulator will accept.

The honest question first

Most lift companies should buy, not build

Plenty of field service products cover scheduled maintenance well. Building only pays off when your obligations sit outside what those products model.

Buy a product when

Your work looks like everyone else's

  • A standard service schedule and job sheet covers the work
  • Your certificate can look however the vendor prints it
  • You manage tens of units rather than thousands
  • Nothing has to be read from test equipment

We will name the products worth shortlisting and leave it there.

Build when

The obligation is the awkward part

  • Your schedule of examination is written by your own competent person, not a vendor
  • Certificates must follow a format an insurer or regulator dictates
  • Engineers work in basements and lift shafts with no signal for hours
  • A defect has to become a job in your own system, automatically
  • Load, brake or overspeed test values come off instruments

These are the parts we have built before, on statutory anchor testing at height and on instrument integration.

Plain definitions

Two things people call lift inspection, and they behave differently

Separating them early decides whether you are shopping for a field service product or building a compliance system.

What is lift inspection software?

It is the system a competent person uses to record a statutory examination and produce the report that follows. The record attaches to one specific car, not to a building. It carries the examiner, the date, the findings, the defect severities and the date the next examination falls due.

Accountability is what separates it from a maintenance app. A maintenance visit produces a job sheet. An examination produces a document somebody signs their name and their competence against, and an insurer may read it years later.

Examination or maintenance?

Maintenance keeps the lift running. A thorough examination is an independent check that it is safe to keep using, and the two are kept apart on purpose. Under LOLER 1998 in the UK a lift carrying people is examined at least every six months, goods-only lifting equipment at least every twelve, or on whatever interval a written scheme from a competent person sets.

In the US the cycle follows ASME A17.1, with a Category 1 test each year and a Category 5 full-load test every five years, and the authority having jurisdiction decides who may sign it. Software that treats an examination as another job type will fight you. The scheduling, the sign-off, the certificate and the retention rules all behave differently.

What we build

Six things a lift inspection platform has to get right

Asset register down to the car
Site, building, lift, car and component. An examination attaches to a specific unit with its own history, not to an address.
Examination scheduling
Six-monthly and twelve-monthly cycles, due dates that survive engineer absence, and a view of what is overdue across the portfolio.
Offline capture in a shaft
Engineers lose signal in basements and machine rooms. Records queue on the device and sync later, with conflict rules that never lose a form.
Defect to repair in one flow
A failed check raises a job with severity and target date, and the report shows what was done about it rather than only that it was found.
Certificates in your format
PDF generated the moment an examination is signed off, matching the layout your insurer or client expects, with the examiner's credentials on it.
Instrument readings where they matter
Load, brake and overspeed values captured from equipment rather than transcribed, using the same approach we built for torque and pull testing.

Who carries the obligation

Four kinds of lift owner, and what changes for each

The examination itself is broadly the same everywhere. What differs is who has to answer for it, and to whom.

Social housing and residential blocks
Hundreds of buildings, one lift in most of them, and a regulator that asks for evidence by property rather than by unit. Overdue examinations are the number the board sees each month, so the portfolio view matters more than the individual form.
Healthcare and institutional estates
Bed lifts and evacuation lifts where a car out of service changes what happens on a ward that day. Defect severity has to drive a named escalation path, not just a colour on a report.
Retail, offices and mixed use
Escalators alongside lifts, several managing agents, and tenants who ask for the certificate before they ask anything else. Reports usually have to carry the client branding rather than yours.
Lift service contractors
Thousands of units inside other people's buildings, engineers billing by visit, and a certificate that has to reach the client the same day. This is where an examination result feeding straight into job management and invoicing pays for itself fastest.

Tell us what you inspect

Three fields. An engineer reads it, not a sales rep. You get an answer within one working day.

  • We look at your schedule of examination and your certificate
  • You get a written view on buy versus build, with a budget range
  • No obligation, and no phone number needed to start

Our work

The nearest thing we have built

We have not yet delivered a lift-specific platform. What we have delivered is statutory inspection at height, instrument integration and device telemetry, which are the three hard parts of one.

Case study, United Kingdom

Statutory testing of anchors and torque, in the field

A digital testing platform for work-at-height anchor and torque checks: scheduled examinations against a defined procedure, capture on site where signal is unreliable, pass and fail logic tied to load values, and a certificate produced at the end that the duty holder can file.

How the work runs

One building running before you commit to the portfolio

  1. Week 1 to 2

    Read the schedule

    We work through your schedule of examination and your current certificate with the person who signs them, and write down what the system must produce.

  2. Week 3 to 4

    Design asset and workflow

    Asset hierarchy, examination cycles, defect severities, certificate layout, and what happens with no signal.

  3. Week 5 to 12

    Build and pilot

    One engineer, one building, real examinations, while we are still building. Demo every two weeks.

  4. Ongoing

    Roll out the portfolio

    Region by region, then the link into your job management or finance system.

Technology and integration

What we build on, and what it has to connect to

None of this is exotic. The difficulty is a basement with no signal and a report that has to be right.

Engineer application
Xamarin and React Native on Android and iOS, built offline first so an examination survives four hours in a machine room with no coverage.
Asset identification
QR or NFC tags on the car, so the engineer opens the right unit and its history instead of searching by address.
Back end and portal
.NET or Node.js behind an Angular or React portal for schedulers, with role separation between engineer, reviewer and duty holder.
Documents
Server-side PDF generation at sign-off, in your layout, carrying the examiner credentials and a stable reference an insurer can quote back at you.
Cloud and identity
Azure or AWS inside your own tenant and region, with sign-in through Azure AD B2C or Keycloak.
Onward systems
CAFM, CMMS, ERP and finance systems through APIs, so a defect becomes a job and a completed examination becomes an invoice line.

Who does the work

Twenty engineers, eight of them senior

Compliance work turns on details that surface only when the person building it has read your schedule of examination. So the people on the scoping call are the people who write the code.

How we work

Five engagement models, and you pick how much you keep

The models differ in one thing: how much of the management you hand over. Everything else, including who owns the code, is the same in all five.

Changing model later is normal. Augmentation into a dedicated team is the common direction, and the people stay.

Engineers join your team and work inside your process, your board and your code review.

FAQs

Questions we get on the first call

Have you built a lift inspection system before?

Not a lift-specific one. We have built statutory inspection for work-at-height anchor and torque testing, which shares the same shape: a defined procedure, offline capture, pass and fail against measured values, and a certificate at the end. We would rather say that plainly than imply otherwise.

Does it work with no signal in a shaft or basement?

Yes. Examinations capture on the device and sync when the engineer gets coverage. This is a normal requirement for us, not an edge case.

Can it follow our own schedule of examination?

Yes, and that is usually the reason to build rather than buy. Your competent person defines the procedure and the system follows it, instead of you bending the procedure to fit a product.

Can a failed check raise a repair job automatically?

Yes, either inside the platform or pushed into the job system you already run. We have built integrations against ERP and CMMS systems, including older ones with no modern interface.

What about load, brake and overspeed test values?

If the test equipment exposes a Bluetooth profile or a vendor SDK, the value can be captured directly rather than typed. We did this for torque and pull testing with the KTC SDK.

Who owns the certificates and the data?

You do. Data sits in your own cloud tenant in the region your policy requires, and all intellectual property in the software belongs to your company.

How long before engineers are using it?

A pilot on one building usually runs 10 to 14 weeks from kickoff, with a demo every two weeks from around week five.

How often does a lift have to be examined?

In the UK, LOLER 1998 sets at least every six months for a lift carrying people and at least every twelve months for goods-only lifting equipment, or whatever interval a written scheme from a competent person specifies. In the US the pattern follows ASME A17.1, with a Category 1 test each year and a Category 5 full-load test every five years. The system holds whichever cycle applies to you rather than a hard-coded default.

Which standards does the software itself have to meet?

None directly. Software carries no certification of its own here, and any vendor telling you their product is LOLER certified is selling you something that does not exist. What the software has to do is produce a record your competent person and your insurer will accept, and keep it available and unaltered for as long as your retention policy says.

Can it replace our CAFM system?

Usually it should not, and we will argue against it. If a CAFM or CMMS already holds the estate, the cheaper build sits beside it and pushes defects across as jobs. We have built that kind of integration against older systems with no modern interface, which is normally the part people expect to be hard.
