This report summarises the results of the quality audits carried out on SCANNER and SRMCS survey and is to provide local authorities, and DfT, with confidence that SCANNER data are consistent and suitable for national performance monitoring, and to support local maintenance operations a quality assurance procedure was developed and fully incorporated into the SCANNER specification. The Department appointed TRL as an independent Auditor, to provide the quality assurance services defined in the SCANNER specification. TRL achieved this by carrying out quality audits and through the provision of independent advice and consultancy services to both survey contractors and local authorities in relation to accredited SCANNER surveys carried out on the English local road network for the financial year 2005/06. In addition to the SCANNER survey of the English local road network, further surveys are carried out on the Scottish Road Network, under a single survey contract, called the Scottish Road Maintenance Condition Survey (SRMCS).
