Culvert Inspections and Drainage Surveys Framework

There is a business need for CCTV/ Man-entry surveys of culverts to assess their operational and structural condition. Blockages identified will need to be cleared, subject to cost, to enable the surveys to be completed. On authorisation from Natural Resources Wales small remedial works identified may be required. In some instances, NRW may require detailed level and dimensional survey of culvert assets to assist downstream data use.
