|Main Contractor||TREVI SPA|
|Duration of work||2015 - 2017|
At the beginning of the 2000s Palermo Port Authority, after terminating the Contract, started to plan the completion works. In order to assess the state of works already carried out, it was necessary to perform consolidation and static safety works before emptying the dock basin.
Works specified in the Contract included dredging of approximately 76.000 m3 of sediments and waste, for a total of about 117.000 tons of mainly sandy material, contaminated by hydrocarbons C>12, heavy metals and mixed waste, mostly conveyed by 2 sewage pipes (about 500.000 AE) which, until 2014, would discharge next to the Dock.
Trevi Spa, after being awarded the Contract, drew up the executive design required to perform works, proposing a washing treatment of the waste to be dredged known as Sediment Washing.
