Accredited testing laboratory · ISO/IEC 17025 · Tbilisi
InfraLab measures construction vibration on site and hands you an accredited test report - evidence that holds up when neighbours complain or a supervising authority asks for proof.

Price depends on the site. Consultation is free.
01 · Risks
Pile drilling, sheet pile installation, soil compaction, demolition - every one of these works sends vibration into nearby buildings. Without data, in any dispute all you have is your word.
“Your works cracked my wall.” Every new crack gets blamed on the construction site - even if it was there before. Without measurements, proving otherwise is almost impossible.
After a complaint, the client or a supervising authority may demand that works stop until the vibration impact is established. Every day of downtime costs money.
If a dispute goes to court, an accredited test report is your main evidence that vibration stayed within permissible limits.
02 · Services
We measure vibration on buildings and on the ground - exactly the two objects covered by our accreditation. Choose the format by the kind of works; not sure which one you need? Call us and we will work it out together.
For a single stage
We come to the site, measure vibration at neighbouring buildings and on the ground while works are under way, and hand you a test report.
For the whole stage
The monitor stays on site for the entire construction stage. If vibration exceeds the permissible limit, you get an SMS or email alert instantly - before damage occurs.
When a complaint is already filed
On the basis of the accredited measurement and test report, we assess the link between vibration and the damage and prepare a written opinion - for a complaint, negotiations or a dispute. The report is accredited; the opinion is the engineer’s professional assessment and falls outside the accreditation scope.
03 · Process
Tell us about the site, the works and the neighbouring buildings. Consultation is free.
An engineer inspects the site and neighbouring buildings and selects the measurement points.
The SV 803 records peak particle velocity (PPV) and dominant frequency on three axes.
You receive an accredited test report: results, charts and a comparison with the DIN 4150-3:2016-12 guideline values. If you need one, a separate expert opinion follows, based on that report.
04 · Trust
An accredited test report only works if the other side cannot call it into question.
The testing laboratory of LLC “Infralabi” is accredited to ISO/IEC 17025:2017. Certificate No. GAC-TL-0375 · The Unified National Body of Accreditation - Accreditation Center (GAC), Georgia. Scope: instrumental measurement of vibration on buildings and ground.
Svantek SV 803 vibration monitor, DIN 45669-1 Class 1, with a valid calibration certificate.
Measurement and assessment follow DIN 4150-3:2016-12 - exactly the method listed in our accreditation scope.
Permissible vibration velocity at the foundation for short-term vibration, mm/s
Guideline values from Table 1 of DIN 4150-3:2016-12 (foundation). Above 100 Hz, the 50–100 Hz values apply. The assessment of a specific building is made by an engineer.
| Building type | 1–10 Hz | 10–50 Hz | 50–100 Hz |
|---|---|---|---|
| Commercial and industrial buildings | 20 | 20 → 40 | 40 → 50 |
| Residential buildings | 5 | 5 → 15 | 15 → 20 |
| Sensitive and listed buildings | 3 | 3 → 8 | 8 → 10 |
05 · FAQ
Developers and contractors working with heavy machinery near existing buildings: pile drilling, sheet pile installation, soil compaction, demolition, excavation. Especially next to old or listed buildings.
Certificate No. GAC-TL-0375, issued by The Unified National Body of Accreditation - Accreditation Center (GAC), Georgia, covers instrumental measurement of vibration on two objects - buildings and ground - by the method of DIN 4150-3:2016-12. We do not present work outside this scope as accredited, and we say so up front.
Test reports are often requested by clients, investors or supervising authorities - especially after neighbour complaints. We measure to DIN 4150-3:2016-12 and will clarify the requirements for your site during the consultation.
It depends on the works. A one-off measurement is taken during a specific activity; monitoring runs for the whole stage (the SV 803 battery lasts up to 6 months). We'll give you an exact timeline after the site visit.
No. We measure under normal operation, while works are under way - that's how real vibration shows up. There's no need to stop work.
A description of the site and the measurement points, the date and conditions of measurement, peak particle velocity (PPV) on three axes, the dominant frequency, charts and a comparison with the DIN 4150-3:2016-12 guideline values. The engineer’s opinion is a separate document, prepared on the basis of that report.
It depends on the site: the format, duration and number of measurement points. Call us - the consultation is free, and we'll quote a price once we know the site.
