general services for participation in start-up and follow-up meetings, reporting and summary files, as well as on-site trips, - controls of the implementation of the works, - leveling checks of structures, - surface topographic controls of the main polygonal and the secondary polygonal, - controls of underground structures (tunnel, voussoirs
, branches, station or well).
This included the huge stone copings on top of the bridge, the voussoirs
- dressed stones that form the arches - and the remains of cast iron rope rollers which ensured boat tow ropes would not get snagged as they were pulled through.
Cette realisation, prouesse architecturale a l'epoque, etait constituee d'une partie centrale, abritee par une coupole hemispherique de 41 metres a la base, de 13 assises de 48 voussoirs
prefabriques, et d'une calotte de 10 m de diametre formee de 24 voussoirs
The report adds: "Other works involve tests to prepare of a full strategy for repairing damage to the capitals and voussoirs
of the vault ribs, and deep cavitation's in the stonework, removal of elements such as salts and candle wax where necessary and finally analyse paint finishes and determine the composition of plaster/rendered finishes.
Thus, it became a veritable "mine" for the construction of the new architectonic complex, clear proof of which we find in the "refuse tip" containing spolia recovered a mere couple of years ago at the former army quarters of Saint Raphael (Torreras 2009; Fuertes, Rodero & Ariza, 2007), located halfway between both buildings and including several seamed voussoirs
from the vault of the ambulacrum, as well as some pieces carved in grey micritic limestone with a very peculiar physiognomy, and perhaps formerly part of the enclosed seats of honour of the proedia (Murillo et al, 2010a, 262-284, fig.
Pour les transports, le groupe fournit des voussoirs
dotes d'une puce (identification par frequence radio) detaillant les informations de tracabilite du produit et permettant d'enregistrer des parametres du contexte de mise en oeuvre (ex: frequence de passage des trams ou metros).
