In this paper we present analysis of building activities, Mayan house, survey and topographical drawing in the Egyptian culture. Due to the nature of these activities, the mathematical knowledge used brings into play two types of theoretical and practical validations. To analyze the role of these two types of validations we used an extended praxeologigal model. The practical validations have an important role, and in our analysis we have characterized these validations. This provides have an important basis to design didactical activities for training future construction technicians.
