Rail and metro noise & vibration — measure, assess, and monitor
Rail and metro projects create both noise and vibration that affect nearby buildings and residents. We measure, assess to standard, and monitor throughout construction and operation. Because rail and metro works run for months or years, monitoring needs to be continuous and defensible, not a one-off snapshot — we set up systems that flag an exceedance as it happens, not weeks later in a report. We work with both the project side, to demonstrate compliance, and with affected communities or building owners who need an independent check.
When to call us
- An EIA condition requires continuous noise or vibration monitoring during construction
- A nearby building owner is concerned about vibration damage from piling or tunnelling works
- You need an operational noise and vibration assessment for an existing or planned line
- The community near a rail alignment has raised a formal noise or vibration complaint
How we help
- Vibration measurement to DIN 4150 and noise to ISO 1996
- Continuous monitoring with exceedance alerts
- Impact assessment for buildings and communities (EIA)
- Modelling and noise mapping (SoundPLAN)
What you get
- Continuous monitoring reports with exceedance alerts
- A noise and vibration chapter or technical input for an EIA submission
- A vibration damage-risk assessment for nearby buildings, referenced to DIN 4150
- Noise mapping and prediction modelling, where scoped
Standards applied
DIN 4150 · ISO 1996 · ISO 9613-2
FAQ
Can you monitor in real time?
Yes — continuous monitoring with automatic alerts.
Do you cover both noise and vibration?
Yes, both.
Do you monitor throughout the whole construction period, or just at set intervals?
Both models exist depending on the project's requirements. High-risk activities such as piling or tunnelling near sensitive structures usually justify continuous monitoring with real-time alerts; lower-risk phases can be checked at scheduled intervals. We'll scope the right approach for your project's risk profile.
Can you monitor multiple sites along a rail alignment at once?
Yes — we can deploy and manage multiple monitoring points along a corridor, with data consolidated into a single reporting system so the project team has one clear view of compliance across the whole alignment.
What is PPV and why does it matter?
PPV, peak particle velocity, is the standard measure of ground vibration intensity used to assess the risk of cosmetic or structural damage to nearby buildings. Comparing measured PPV against DIN 4150 thresholds tells you whether construction vibration is within a safe range for the structures nearby.
