EXCAVATIONS
- LANDFILLS AT THE LOCATION
OF THE ARTIFICIAL ISLAND
| The new modified
cross section of the caissons that was proposed after the new geotechnical
studies resulted in an increase in the excavation of the sea bottom
from -16.00 m to -20.00 m. This led to an increase in the cubic metres
of excavation from 60,000 to 231,000 m^3. The new amount of excavations
was dealt with a LIMA 2400 oil tanker and the use of two 350-m^3 long
barges. |

For the above
reasons, there was a considerable increase in foundation ripraps; on
the other hand, there was also an increase in the absorption of the
riprap of more than 30% coming up to a rejection. The Ministry of Public
Works (supervising agency) accepted a percentage of absorption coming
up to a rejection on the order of 10%. |
This increased amount of ripraps was dealt with
amounts coming from existing Myconos quarries and with transport of large
amounts of riprap from other islands (Chios, Paros, Samos).
