Independent measurements · Moscow and Moscow Region
I visit the site, measure the lift's actual parameters with my own instruments, compare them with the requirements of TR CU 011/2011 and GOST standards and prepare a written opinion — for court, or for a claim against a contractor or a management company.
Sample line from an opinion
Every value comes with the instrument used, its serial number and calibration certificate, plus photo and video records.
01 — When you need an opinion
The contractor has handed over the lift, but the car stops with a step, the doors slam and the winch is noisy. I record the deviations before the acceptance certificate is signed.
Frequent breakdowns, downtime, lift maintenance fees while the lift is actually faulty. The opinion becomes the basis for a claim and a lawsuit.
A fall on the threshold, an injury from the doors, being stuck. I measure the parameters relevant to what happened before they are changed by repairs.
Owners need to know the actual condition before deciding on replacement or modernisation, and to check it against the conclusions of the examination.
I check which methods and instruments were used for the measurements in the expert's report and whether they comply with GOST 34583-2019.
Car and door opening dimensions, button height, signalling — checked against GOST 33652-2019.
Key date
Lifts whose assigned service life expired before 15 February 2025 must be brought into compliance with TR CU 011/2011 by 15 February 2030.
Decision of the EEC Council of 29.11.2024 No. 112. Mass replacements mean mass disputes over installation quality.
02 — What I measure on site
Methods follow GOST 34583-2019 "Lifts. Rules and methods of tests, measurements and checks during operation". Limits follow GOST 33984.1-2023 and the manufacturer's documentation.
| Parameter | Checked against |
|---|---|
| Car stopping accuracy at floors | GOST 33984.1, lift passport |
| Gaps between door panels and frame, car–landing step | GOST 33984.1 |
| Force needed to prevent the doors from closing | GOST 33984.1 |
| Car travel speed | GOST 34583, lift passport |
| Illuminance in the car and on landings | GOST 33984.1 |
| Car and opening dimensions, height of controls | GOST 33652-2019 |
| Noise level in the car and in flats | SanPiN 1.2.3685-21 |
Specific limit values are taken into the opinion from the current edition of the standard and the passport of the particular lift.
03 — Regulatory framework
A common error in other people's opinions is citing repealed acts. Resolution No. 743 ceased to apply on 1 September 2024, and GOST R 53783-2010 was withdrawn on 1 June 2021. An opinion that relies on them is easy to challenge.
04 — How we work
Together we define exactly what the opinion should establish. I request the lift passport, certificates and correspondence.
Measurements are taken in the client's presence; where possible we notify the other party so that it can attend.
On site — a record of "declared / actual" results, signatures of those present, photos.
Study, answers to the questions, conclusions, appendices. Paper copy and PDF.
A specialist opinion is written evidence and a consultation. It does not replace:
But it helps to justify a motion for an expert examination and to word the questions for the expert correctly.
05 — Prices
I work under a contract and issue a receipt. Prices are per lift in Moscow; for several lifts in a building and for Moscow Region — by agreement.
from 9,000 ₽
from 36,000 ₽
from 75,000 ₽
06 — About the specialist
Specialist in the operation of lift equipment
I visit the site, measure the lift's actual parameters and prepare measurement records and opinions. I am not affiliated with lift companies or management companies, so I can check their work.
Two university degrees — in construction and in electrical engineering — make it possible to assess both the building part of the lift (openings, steps, dimensions) and the electrical part (lighting, signalling, controls).
07 — Calculators
A rough self-check with a tape measure and a stopwatch. If the result raises doubts, accurate measurements with calibrated instruments are needed.
Measure the car floor from the inside, wall to wall.
The area does not exceed the limit for the declared rated load.
The area exceeds the limit: more people fit in the car than the lift is designed for. This area requires a rated load of at least — kg.
Approximate, based on the maximum car area table of GOST 33984.1 with linear interpolation. Passengers = rated load / 75 kg.
The year of commissioning is in the lift passport or on the plate in the machine room.
If the passport does not state the service life, 25 years from commissioning is assumed. Calculated by year, ignoring the month.
Time a full round trip with a stopwatch: from leaving the ground floor until returning to it, with stops on the way, at peak hours.
No worse than the satisfactory comfort level (interval up to 100 s).
Interval over 100 s — worse than satisfactory. There may be too few lifts, or they run slower than their passport parameters.
Simplified: interval = round-trip time / number of lifts. Comfort levels per GOST R 52941-2008 (satisfactory: 81–100 s).
Count the days without a lift from your calls to the dispatcher or photos of notices in the entrance.
Keep request numbers, dates and the management company's replies — they make up the downtime timeline for a claim.
Take the number of storeys and the storey height from the building’s technical passport, or measure floor to floor.
A lift is required: the top floor is more than 12 m up (clause 9.16 of SP 54.13330.2022).
The top floor is no more than 12 m up — SP 54.13330.2022 does not require a lift.
The car can carry a person on a stretcher: one side is at least 2100 mm (clause 9.17).
A car side is under 2100 mm. Unless another lift in the building has such a car, clause 9.17 is not met.
The top floor level is counted from the ground floor: (storeys − 1) × storey height. The minimum number of lifts is set in Appendix V of SP 54.13330.2022. Older buildings follow the rules in force when they were designed.
Measure the step between the car floor and the landing floor with a ruler. Check several floors going up and down.
Within tolerance for any lift.
Acceptable for a lift without re-levelling. If the passport says it has re-levelling, the ±10 mm tolerance is already exceeded.
The step is over 35 mm — beyond tolerance for any lift. This is a reason for precise measurement and a claim.
Tolerances per GOST 33984.1-2023: ±35 mm without re-levelling, ±10 mm with it. A ruler gives an estimate; court needs measurements with verified instruments.
08 — Checklist for residents
Once the acceptance certificate is signed, it is much harder to prove that a defect was there from the start. If even one item fails, write a remark into the certificate or call a specialist.
Invite me to the acceptance09 — Questions
A court-appointed examination is ordered by the court. You order a specialist opinion yourself — before or during the proceedings. It is added to the case file as written evidence and often becomes the basis for a motion for a court-appointed examination.
The court assesses it together with other evidence. The chances are higher when calibrated instruments, a GOST method, current standards and photo records are stated and the other party was notified of the measurements. When summoned by the court I give explanations in person: in a court of general jurisdiction under Art. 188 of the Civil Procedure Code, and in an arbitration (commercial) court (disputes of homeowners' associations and management companies with contractors) under Art. 55.1 and 87.1 of the Arbitration Procedure Code.
For most measurements, no: stopping accuracy, doors, light, noise and dimensions are measured from the car and the landings. I do not access the equipment or the shaft — that is the responsibility of the servicing organisation.
For measurements from the car, no — the lift is available to residents. But it is better to notify the management company and the contractor of the date in writing in advance: then it is harder for them to claim they were denied the chance to attend.
No. Inspection and examination of lifts are carried out by accredited inspection bodies and laboratories. I independently measure the actual parameters and can check whether they match their certificates.
Measurement record — on the day of measurement; opinion or review — from 7 working days. We agree the visit date when you send the request. If a court hearing is coming up soon, state its date in the request.
