DEVELOPMENT OF A BIM INFRASTRUCTURE WORKFLOW ADAPTED TO FACILITIES OF LAND SUBDIVISION PROJECTS IN MOROCCO

Land subdivision represents a complex procedure which leads to the construction of a set of buildings and utilities necessary for the viability of the project: Roads, sewerage network, water network, electricity network and telecommunication networks. The techniques adopted so far to carry out land subdivision projects in Morocco have certain limitations. Several stakeholders are necessary for the realization of a land subdivision and many 2D plans and documents are used. These plans and documents are independently produced and carried out by the various trades involved in the project. If a change is made to one element of the project, which often happens, several documents and plans are affected and must be updated. This can be a source of errors and conflicts and can lead to an increase in the time and cost of the hall project. This study proposes the development of a Building Information Modelling (BIM) infrastructure workflow adapted to land subdivision projects in Morocco. The integration of BIM in this type of project is an innovation in the Moroccan context. It will improve the design, simplify communication and collaboration between the various stakeholders and facilitate the management and the monitoring of the project. The resulting digital BIM model can be used to produce 2D and 3D construction plans, take measurements and plan work. It constitutes the basic platform to perform calculations and simulations at any stage of the infrastructure life cycle and to detect and resolve interferences in a collaborative environment.
