Mobile buildings are assembled in a factory controlled environment and offers the following benefits: - Fabrication is done in parallel to site planning and site works resulting in a significant time saving. - Quality control at the factory and not at dispersed and distant sites - No weather delays – fabrication takes place in a factory - No waste on site - Safety: limited activity on site (takes 1 day to site the building) and limited interference if the school is in progress - Material control – no material on site which is often subject to theft
