Construction of earth and rockfill dams

ByChristian Kutzner

The work of river diversion marks the beginning of the construction period after the site has been made accessible by roads and after the first steps of site installation permit such work. Small river discharges are conducted across the site through pipes. Large discharges require cofferdams and different structures of the diversion system. Frequently, river diversion is contracted ahead of the main works as an individual contract.
