This season, work on tomb IV in the domus de janus necropolis concentrated on the anterior part of the dromos and adjacent room b, where the excavation was completed. In both zones, all stratigraphic units next to the walls were affected by severe alterations.

The intervention in the corridor was limited to the excavation of US 112 and 114, corresponding with the phases of flooring and subsequent restructuring, characterised by cobblestone surfaces, polygonal stones, and small slabs. A photogrammetric survey was undertaken in the corridor, with the collaboration of Oben s.r.l., a spin-off of Sassari University.

In chamber b, the paving slabs (US 100) partially made of reused worked blocks from earlier structures were removed. Beneath lay a series of badly-preserved occupation layers. These consisted of the remains of a beaten crushed limestone surface (US 115), cobblestone surfaces, well-preserved in limited areas (US 116 and 119), an extensive very compact layer (US 117), a central zone with evidence of burning (US 121, 123), probably a badly-preserved hearth, with irregular edges, and areas with a high concentration of charcoal (US 123). There was a beaten crushed limestone surface across almost the whole area, overlaying the floor, only preserved to a thickness of c. 20 cm by the north-west wall. In the rest of the chamber it had been almost completely removed (residual to a maximum thickness of 2 cm), as attested by visible cuts and holes. Adjacent to the entrance wall there was a very compact fine-grained layer (US 122) and the beaten lime surface was not present in this strip. Two irregular holes opened in the floor, probably natural in origin, a shallow sub-oval pit, and a circular cup-mark with a flat floor.
