The work presented in this paper, aims to construct a Building Information Modelling (BIM) related to productivity in the rehabilitation of residential buildings in Algeria, due to a large dilapidated housing stock, by providing a simulation model to optimize the productivity ratio in the rehabilitation building project for less expenditure and time saving. A large number of rehabilitation projects are confronted to a major problem in terms of financial support because of the age and complexity of the proposed quantities of rehabilitation work needed to be undertaken. A statistical analysis was carried out on the data collected on the sites studied and discussed in this document.
