Do I need a PAS 128 survey for a water infrastructure or AMP8 scheme?

Yes — on any scheme involving excavation near buried services. This includes AMP8 mains replacement, treatment works upgrade and pumping station installation programmes. Water infrastructure sites often carry decades of buried services — water mains, sewer infrastructure, gas supply, electrical cables and communications — not all of which will be accurately represented in utility records. PAS 128 Quality Level A physically verifies the location of every service. It is the standard that protects the programme from underground strikes and the Principal Designer from CDM compliance gaps. We are PAS 128 accredited and deliver utility mapping across the United Utilities supply chain in the North West.
