What is a PAS128 Survey Type C (Site reconnaissance)?
As defined in PAS128 it is “A site reconnaissance to identify physical features that support the existence of utilities within the survey area.”
Why would I consider requesting a PAS128 Survey Type C?
Survey Type C is a quick and cost effective way of verifying initial accuracy of owner provided utility information. Dependent on size most sites can be completed on site by a utility survey team with a single day visit.
A utility survey team will visit the site; they will have with them all owner provided utility information (Survey Type D). The goal of this site visit is to identify and locate all manhole / inspection chamber covers, valve covers, utility markers, control and distribution pillars/columns, LV power, street lighting, traffic lights, and historic excavation scar lines.
All features located on site will be recorded using GNSS and total station to enable accurate mapping.
Survey Type C does not include the use of any utility detection equipment, so the highest quality level any utility can be given is QL-C following PAS128 format.
All utility survey data will be presented in digital model format to clients specified requirements and a survey report will be provided which will include list of utilities within site area, which utilities where verified present by on site visual inspection, recommendations on how to proceed with further site investigation if it is required and where possible photographic site evidence to support survey findings.
