Canal cleaning and canal inspection

Summary

The tender concerns canal cleaning and canal inspection works for drainage systems along the highway project, including renewal of AKR-damaged concrete pavement and bridge decks. The drainage lines will be cleaned using high-pressure water flushing or equivalent methods based on camera-detected damage; before flushing, camera footage will document the level of contamination; after flushing, canal inspection will document the cleaning results and any damages. Documentation must be prepared according to ISYBAU in XML format, organized by kilometre with separate rehabilitation recommendations. The work site is located on the A4 motorway between the Rüdersdorf junction and the Hermsdorf interchange, km 147.3 to about 152.1 in both directions.
