The UTICA laboratory is a non-profit association that was created in 1988. It is located in the Archaeological Unit's headquarters. The lab is a member of the national network of decentralized workshops under the direction of the Musées de France, and works solely on archaeological objects from public collections or excavations led by INRAP, local authorities and the CNRS. It also takes part in French missions abroad.

UTICA works on metal objects and those made of organic materials, whether waterlogged or not (wood, leather and bone), and on composite objects made of these materials. The lab also treats rarer materials, including amber, lignite, mother-of-pearl, ivory, horn and bark.

In addition, UTICA is available to archaeologists for any and all questions concerning the removal of objects, collection maintenance, organization of the reserves, and museographic presentation.
