mobile barriers are in operation, a main passage for
navigation, is being constructed at the Malamocco inlet
to allow the transit of large ships. At the Lido and
Chioggia inlets there will be smaller locks to allow
emergency vessels, fishing boats and pleasure craft to
shelter and transit.
Fagioli between 2012 and 2014 was involved in the
transport and installation of beams, weighing between
600 and 900 ton with a length of 57 m, for the
syncrolyft structure (pict 03 a 03 b), a huge elevator
device used to gently move the caissons into the water
, ready to be dragged away and installed. The syncrolift
was used at Malamocco port whilst at Lido and
Chioggia ports, the caissons
construction site were The project is an integrated defense
flooded with water allowing system composed of mobile gates able
the caissons to be dragged to isolate the Venetian Lagoon from
away. Fagioli used a gantry the Adriatic Sea when the tide reaches

to build up the syncrolift announced flood
structure. Fagioli was also
involved in the transport and
installation of 12,000 ton concrete caissons, by means
of a tailor made “catamaran” (pict.04) constructed by
securing two 190 ton river barges (39,2m x 9,7m x
3,82m) with a pair of steel cross-head beams. The
catamaran was provided with strand jacks used either
for the pulling and lowering operations of the concrete
items. After the final positioning of the caissons, Fagioli
executed the transport, lifting and final lowering

total of 78 gates which will constitute 4 barriers, posi-
tioned at the main entrances of the lagoon.
Each barrier (paratoia) is 20 m wide with a length
varying from 18.5 to 29 m and (3.6 to 5 m thick) (pict.
02) The barriers are connected to 12,000 ton concrete
caissons.
In normal condition tide, the barriers are full of water
and rest in horizontal position inside the caissons. With
high tide, compressed air is introduced into the gates to
empty them from water, rotating around the axis of the
hinges and rising up until they emerge above the water
to stop the tide from entering the lagoon. In order to
guarantee navigation in the Port of Venice when the
