During this campaign, excavations were limited to areas 8, 4, and 5, the nave and left aisle of the church (Building A) and the south-western part of Building F. The results provided a more accurate picture of the 14 occupation periods identified for the site.
Pending the continuation of excavations, a comparison between the most complete contexts made it possible to interpret the clear traces of working present in the central part of Building F (Area 5) and the aisle of Building A (Room 3), as activities associated with the dismantling of public or private imperial structures in order to recover metals to be reused in the construction of new Christian buildings or melted down for trade, practices well-attested in other Italian contexts.

The work area investigated in Room 3 may be interpreted as the zone where the recovered objects and furnishings were melted down and used in the working of copper alloys. The furnace floor (1290, 1374, 1376, 1382, 1392) could be identified as the furnace used for melting down metal, while several reddened and carbonised circular patches may constitute the remains of forges (1289, 1305, 1351). The absence of earlier walls, contrary to what was documented in Area 5, and post holes for supporting a roof, suggest that this was an outdoor work space, which is for that matter an indispensable condition when re-melting metals. The part of Building F where the same activities took place (Area 5), may have been used for forging or reforging iron. In fact, analysis of the traces preserved in the soil, the size of the work area, and the finds coincide with what has been documented in Tuscan contexts associated with metalworking.

The large amount of slag found in the adjacent room, whose only entrance was blocked prior to this activity, shows that the walls of Building F were already demolished or partially razed during the 5th century, but not so far as to prevent adequate protection, integrated with temporary structures, for the work areas. Only one posthole (1434) was found for the roof, therefore, the walls must have been at least partially standing, as the roofing would have been partially present in order to provide the shade necessary for recognising the temperature reached by the metal in the forge, but allowing space for the fumes to escape.

Therefore, following its change in function, the room to the south-west was used exclusively for dumping slag and waste products from the production. This particular differentiation in the use of rooms in the same building may also explain the different state of preservation of the mosaic floors, with the one to the south-west being very well-preserved.
