Further it should be ensured that dike would
be reconstructed in the shortest possible time.
For example, if pipes have to be laid through
the dikes, the pipes should be laid quickly
and plugged/capped so that the dike can be
closed. Thereafter balance or pipe fabrification
can continue without any risk. Standby
