All contracting related to the construction of buildings and the like is considered commercial work as long as the contractor undertakes to supply the necessary supplies and tools. Therefore, “opinion has settled on including all real estate contracting, and therefore its ruling applies to demolition and restoration contracting, road and bridge contracting, laying water pipes and telephone wires, digging wells and opening tunnels.” In order for a real estate contracting to acquire a commercial character, the text requires that the contractor undertake to supply supplies and tools. However, the French and Egyptian judiciaries agree that the contracting is commercial, even if it is limited to providing labor, because work can be, like goods, a subject of speculation. However, it should be noted that if the contracting work is limited to managing the work only without providing raw materials or workers, then the contracting is considered a type of civil work. Likewise, the work of engineering offices that are limited to drawing up architectural drawings without implementing them is considered civil. All of these works are considered commercial if they are carried out. As a matter of professionalism.
