Eight temporary towers visible from outside the facility
The Raw Materials Yards covering works are proceeding to plan. From the outside of the Taranto facility perimeter fencing the eight temporary towers are now visible: 4 are around 80 metres high and 4 are 15 metres high, and they will be used to raise and assemble the upper part of the covering. In addition to the installation of all the towers, the foundation plinths were constructed following the driving of the 318 foundation piles (each around 38 m long) that will support the entire structure. The steel structure work for the towers and roofing arches is being carried out by Cimolai employees, while for the civil works (foundations and piles) Cimolai has engaged local contractors. There are now some 160 people working regularly on the site.
Cimolai technical works director Marco Sciarra has confirmed that “construction of the metal structure, being produced in the workshops, is on schedule. In this phase,” the works director continues, “we’re working in an area over 60,000 m2 (out of a total 180,000 m2)”.
On completion, this will be a work of world-class engineering requiring 60,000 tonnes of steel, 200,000 m3 of concrete, 10,000 tonnes of reinforcement and 25,000 m of foundation piles.
Safety containment of the surface aquifer in the Raw Materials Yards, provided for in Prime Ministerial Decree 2017 pending construction of the covering, has been active since 1 June 2018.
This task involves the operation of 11 pumps to drain surface water from a trench (maximum capacity of each pump = 1 m3/h) and the channelling of such water to a treatment plant with a maximum capacity of 480 m3/day, working round the clock, 7 days a week. The plant provides sedimentation, coagulation and flocculation, sand filtration and active carbon absorption to make the water comply with the legal parameters for discharge into surface water.
Water from excavation for the covering of the Raw Materials Yards also goes to this treatment plant.
