Construction Vibration Limits in South-East Asia and Where DIN 4150-3 Fits

A typical vibration dispute starts like this. A contractor drives piles or runs a vibratory roller, a neighbour finds a crack, and both sides produce a number. The contractor quotes 15 mm/s, the neighbour's engineer quotes 5 mm/s, and both are citing a real standard. They are simply measuring different things at different places on the building.

This is the comparison for Thailand, Malaysia, Vietnam and Indonesia, the four countries in the region with their own written criteria, and how each relates to the two European standards that sit behind almost all of them: DIN 4150-3 (Germany) and BS 7385-2 (UK).

A vibration limit means nothing without three things: the frequency at the peak, the measurement position, and whether the vibration is short-term or continuous.

The comparison

Thailand is DIN 4150-3 in disguise

Notification No. 37 looks like a Thai standard because it writes the limits as formulas: for a Type 2 building (houses, shophouses, condominiums, hospitals, schools) the foundation limit between 10 and 50 Hz is 0.25f + 2.5 mm/s. Work it out and you get exactly the DIN 4150-3 line for dwellings: 5 mm/s at 10 Hz, 15 mm/s at 50 Hz, 20 mm/s at 100 Hz. Type 1 (factories, offices, warehouses) and Type 3 (monuments and fragile cultural buildings) follow the other two DIN lines in the same way.

Two details catch people out. First, the notification has two cases: vibration that cannot cause fatigue or resonance, and vibration that can. For a residential building the top-floor limit drops from 15 mm/s to 5 mm/s in the second case, which is where long piling campaigns and vibratory compaction often belong. Second, it specifies where the sensor goes: on the lowest floor near the outer wall, no higher than 0.5 m, fixed to the structure. A geophone sitting loose on a garden path is not a measurement under this notification, and a monitoring programme set up that way can be rejected as evidence.

Malaysia allows more, and says so

The 2021 DOE guideline replaced the 2007 edition and is far more complete: 118 pages covering human response, sensitive equipment, blasting and building damage. For damage it reproduces BS 7385-2, which permits 15 mm/s at 4 Hz for a residential building, rising to 50 mm/s from 40 Hz. That is three times the Thai figure at the same frequency. The guideline halves those values for continuous vibration, gives the DIN 4150-3 lines as an alternative, and is explicit that a limit does not guarantee the absence of cosmetic damage.

In practice the choice between BS 7385-2 and DIN 4150-3 is made in the EIA or the approval conditions. If you are the contractor, check which one before you price the monitoring. If you are the neighbour, check whether the reported figure is a transient or a continuous limit.

Vietnam regulates annoyance, not damage

QCVN 27:2025 replaced the 2010 regulation in November 2025. It is a human-response standard: a weighted acceleration level in decibels, 70 dB by day and 65 dB at night at most receptors near a construction site, with +10 dB allowed if the work lasts no more than two hours a day. It contains no building damage criterion. A Vietnamese project that monitors only to QCVN 27 has no answer when a wall cracks, so specify DIN 4150-3 or BS 7385-2 alongside it in the contract.

Indonesia grades by building condition

The 1996 decree is the only one of the four that classifies buildings by their state rather than their use: 5 mm/s for a building that already has visible cracks, 10 mm/s for one in good condition. That makes a pre-construction condition survey part of the limit itself. Without photographs and a crack log before work starts, nobody can say which category a building was in.

What to put in a monitoring plan

• State the criterion, the edition and the line or category for each receptor, for example DIN 4150-3:2016 Table 1 line 2 at the foundation, not just "DIN 4150".
• Record the dominant frequency with every peak. Without it a Thai, German or British limit cannot be applied, and a 6 mm/s event at 8 Hz and at 45 Hz have very different meanings.
• Set an alert level below the limit (70 to 80 percent of the limit is common practice) with real-time notification, so the contractor can change method before an exceedance rather than after it.
• Do a condition survey of every receptor within the zone of influence before work starts. In Indonesia it decides the category; everywhere else it decides the argument.
• Use a monitor whose calibration certificate is current and traceable. Thailand names DIN 45669-1 for the instrument; a court will ask for the certificate.

Geonoise runs construction vibration monitoring with online alerting to these criteria, and Acoustic Laboratory Thailand calibrates vibration sensors traceably. If you have a piling or demolition job next to occupied buildings, send me the site plan and the nearest receptors and I will tell you which limit governs and where the sensors should go.
