The work was divided into two sectors:
1.Organisation of the area with a view to its enhancement;
2. Excavation of domus de janas IV.

1. The spoil heap formed during excavations in the 1970s, from the moment of the discovery of the necropolis until the interruption of the research in 1984, was partially removed. This spoil heap contributed to hindering rainwater drainage, causing the pooling of water on the excavated surfaces. Massive accumulations of material excavated by mechanical means and placed on top of the other hypogea to protect them during the construction of the fly-over and the Borore-Olbia road, unfortunately remain in place.

These spoil heaps and accumulations have altered the landscape surrounding the necropolis, which should be restored. With the removal of the spoil heaps the situation was certainly improved. However, this work needs to continue, eliminating the accumulations and completing the reconstruction of the environment, involving the owners of the land and necropolis, that is the Province of Sassari and the town of Illorai.
2. Excavations mainly involved the dromos, begun in 2014. The state of preservation of the surface, damaged by the pooling of rainwater, caused problems in identifying the last layers excavated in 2014.

The removal of the disturbed layers (US 43) revealed the traces left by the bulldozers teeth used in the 1970s by the construction company, which had badly damaged the tomb and, partially the sediments.

A structured hearth was found by the east wall of the dromos (US 46 and 47).
In synthesis: 19 US were identified, numbered 43-61.
The archaeological materials (pottery, lithic and animal bones) numbered 806 (ns. 724-1530).
Ceramic finds were predominant over the lithics and faunal remains. The soil from identified and undisturbed contexts is undergoing floatation.
