ABSTRACT
For professionals in the building trade, the construction site obviously provided income from which they made their living. Some were working in a branch of activity clearly specialized in the building trade, as was the case with quarrymen, stonemasons or carpenters. From an historiographical point of view, the building sector thus came to fit into “the industrial revolution of the Middle Ages”. The qualification of professional was far from trivial in the Middle Ages, as was the issue of “professionalization”. Medieval construction sites have often been reduced to cathedral construction in the historiography, which moreover has also reduced architecture to monumental buildings only. Just as with wages, supplies were subject to multiple variations linked to the type of material concerned, and each variation helped to shape the work and wage regimes of a specific construction site. The supply of raw materials was a crucial aspect of any construction project.
