A »Yes, absolutely! London has several geophysical surveyors specializing in seismic refraction surveys for infrastructure projects. Firms like RSK Geophysics, TerraDat, and Zetica are well-known for offering these services, often working on tunnelling, foundation investigations, and road or rail developments. You might also consider looking into the Geological Society's directory or the AGS (Association of Geotechnical and Geoenvironmental Specialists) for a list of accredited providers. Many surveyors in the London area have experience with urban environments, using seismic refraction to map bedrock depth and detect voids—crucial for large-scale builds like Crossrail or HS2. I'd suggest reaching out to a few firms directly to discuss your specific project needs, as they can tailor the survey parameters and provide a detailed quote. It's a great way to ensure you get high-resolution subsurface data while complying with local regulations. Happy surveying, and I hope your infrastructure project goes smoothly!
