The work was divided into three sectors:
1.Organisation of the area with a view to its enhancement;
2. Laying out of the grid and setting up of the excavations;
3. Excavation of domus de janas IV.

1. The sediments that had accumulated over the last 30 years were removed from the three chambers of tomb I, which can now be visited.
A covering system for the hypogea is in the study phase, in view of opening to the public.
Petrographical analyses are being carried out at Caglieri University, the results will establish regulations for the monitoring and consolidation of the rocky substrata.

2. Once point 0 was established, the area was divided into 5 × 5 m squares running north-south. The gird used in previous campaigns, arranged in parallel with the front of the hill section caused by the excavations undertaken using a mechanical digger for construction work, was inserted into the new system.

It was chosen to excavate tomb IV, as it was protected by the flyover, and in appearance did not present any logistical problems. The earlier 1 m grid in the area was reconstructed.
The flotation of the excavation sediments, in some cases removed intact was carried out at Cagliary University’s Centre for the Conservation of Biodiversity.
3.Tomb IV was still covered by the nylon sheeting that had been put down at the end of excavations and showed no signs of having been disturbed.
The hypogeum was formed by the dromos, semicircular antechamber, and two quadrangular chambers (cella 1 and cella 2). Chambers 1 and 2 were completely excavated; there was residual stratigraphy in the antechamber, which seemed to continue in the dromos: excavation of the dromos began. Cella 2 did not produce any archaeological material; cella 1 contained a funerary context of the Bonnanaro culture, situated in the north-western corner on the floor; in the antechamber there were several contexts of the Ozieri culture. Radiometric dating is being carried out.

The pottery and lithic materials were abundant in the antechamber, in association with palaeo-botanical and palaeo-faunal remains.
Digging tools (picks, wide bladed implements, scrapers etc), intact or fragmentary, used and unused, were prevalent among the lithic artefacts.
In synthesis: 42 contexts were identified
Archaeological finds inventoried: 723
Sediment and/or charcoal and carbonized seed samples: 44.
The graphic and photographic documentation was digitized.
