The roadworks seem almost complete... But there are no road markings or signs. Without further clarification, and as the official documentation (https://www.orges.ch/_files/ugd/32d62d_628960d79caf4a6392ea63136d704f92.pdf) uses the word “rond-point” (traffic circle), I think it's a “priorité à droite” (right of way) and not a “giratoire” (priority to vehicles already on the ring).
