Abstract: The Small Baths was one of the most innovative building from the second century: if the preservation of the structures allows to analyze the spectacular architectural solutions, a clear understanding of the heating system was reached only after several excavation campaigns.
In 2009 the excavation of the boiler room was a meaningful phase, allowing for the first time the analysis of the baths’ “engine” .
The discovery of a large furnace and the “reading” of the traces left by the now missing metallic elements, has enabled to spot on technological solutions, obtaining a clear map about the heating rooms and the water management of the building.
The survey documentation has been carried out with laserscan technology: a first survey was made in 2004, during the first excavation of the octagonal hall, the second survey, aimed to the study of the general building asset, was made after the completion of the excavation. A photographic survey was executed to create a complete database about the material elements of the building. A third, specific survey was made in the boiler room, before and after its excavation, with particular attention tho the connection system between the room, the rest of the building and the relationship with the nearest constructions.
Starting from this group of graphical documentations, it’s now possible to develop some digital simulations and diagrams to study and to reconstruct the technological system of the boiler room and of the piping: using the survey data it’s possible to create some 3Dmodels of the area and to give some useful elements to the archeological analysis and to develop a understanding about how this system was working. A further presentation of the overall enhancement in the knowledge about this system will be also defined in a graphical way to allow a dissemination of the results.
