Pas128 2022

Quality Levels set out the accuracy to which the survey data is captured for specific purposes, the quality expected of that data and a means by which to assess and indicate the confidence that can be placed in that data.

PAS 128 compliant utility survey will consist of many underground utilities and it is possible that all of the Survey Category Types will be featured in some way.

A particular single utility may have several QL designations along its route depending on whether it has been exposed (verified), successfully detected or taken from utility records at a particular section along its length.

The complete package in line with the PAS128:2022 specification.

SVS have always prided themselves on going the extra mile when it comes to utility mapping.

“All of our surveys are carried out to the Pas128 and / or RICS standard specification and produced in AutoCAD DWG, PDF, DXF or revit”

The PAS specification outlines key stages (survey types) to obtain the most
comprehensive and informative survey results for your site. The survey types are;

Survey Type D: Desktop search and compilation of existing asset information
Survey Type C: On site reconnaissance with the desktop search in hand, this is an initial fact finding mission designed to establish those factors that may impede progress on site in advance of the survey taking place
Survey Type B: On site Utility Investigation and Survey. Mobilising to site with the latest technology our qualified and highly trained staff will look to determine position and depth of all buried utility services. All services are then offered a confidence rating as to their detection; QL-B1 being high to QL-B4 low and mapped using topographical devices
