Dig Safe BUILDINGSYARDS

POLLENZO: EX SAVOIA ROYAL ESTATE
 
This work underlines the compatibility of the suction technology with the delicate historic structure. The aim was to empty debris from vaults and demolished overstructures. It has been used a forked suction hose in order to work with four operators:

two for every suction point, one to move the material which was sometimes compacted and the other at the top of the suction hose.
 
This technique has accelerated the operations of debris removal improving the working conditions for operators and limiting physical contact with debris. Moreover this method did not disturb the life of the city, because the traffic was not diverted and the traditional market took place as usual.
 
PADUA: PALAZZO della RAGIONE
 
The south loggia of Palazzo della Ragione (1218, AD) in Padua has been restored. The suction excavator was used to remove guano, rubble, and dust in the loft of the loggia.
O
nly one small-size access was practicable in the intrados of the vaults. The suction excavator was located in Piazza delle Erbe from where started the very light hose, 150m long, to pass through the access and then to run along the extrados of the vault.
The air filter system, placed inside the suction tank, assured the absence of dust during the operations. In this way the debris has been sucked where it was produced and then unloaded in cofferdams and authorised dumps.
 
SIENA
 
The underground of the city of Siena is full of tunnels excavated in tuff which have been filled up with rubble and other materials during the restoration phases of old buildings.

The operation consisted in the removal of about 150mc of rubble. The two axis mini suction excavator was located in a particular position in order to unload rubble on a small truck (3.5 ton) which carried it in storage areas.
The suction hose went down for about 10m through a hole in the flooring of the ground storey removing the material in safety working conditions.

It was used the suction excavation method. The yard with the suction equipment was placed at the end of rio terà S. Leonardo occupying a central part of rio terà Farsetti (6m wide 30m long), that is only 1\10 of the space occupied by a traditional yard.
The channel was drainned closing with a cofferdam Canal de Cannaregio and maintained dry by an automatic draught pump.
The speed and the reduction in the number of operators have been the main features of this method. The work was well-done cleaning completely the vault without further manual finishing.
 
The channel was emptided using the same method of Rio Terà S.Polo thanks to a video-controlled suction mini digger
