Our PAS 128 utility surveys deliver high-quality subsurface data in accordance with the British Standard for underground utility detection. Using a structured methodology (Types D, C, B, and A), we combine desktop records searches, visual inspections, electromagnetic location (EML), and ground penetrating radar (GPR) to classify utilities by quality level and confidence. Every survey is carried out by experienced surveyors and geo-data specialists, ensuring safe excavation planning, reduced risk of service strikes, and full regulatory compliance.
