  • The term industrialized construction was adopted by the offsite construction industry where the building components are prefabricated in factories and then transported to the construction site for on-site assembly. With this shift towards industrialized construction, new challenges were encountered, especially in terms of accommodating the constraints of the machinery and verifying the manufacturability of a project. Despite these challenges, as the buildings are completed by the automated machines in the production lines, it is now feasible to estimate the production time and the associated cost with a higher level of accuracy. Additionally, as applications of building information modelling (BIM) are being increasingly employed in industrialized construction, a significant benefit is gained in terms of data sharing and transformation between the phases of a project. In this research, a framework for a BIM-based automated system is developed with the aim of linking the 3D BIM models with the automated machines used on the production lines to check the manufacturability of the building components depending on the machines’ limitations. Additionally, the proposed automated system generates the computer numerical control (CNC) codes, which are required to manufacture these components directly from the BIM environment, which eliminates the need for third-party tools to generate the CNC codes. To generate accurate and detailed production duration estimates, the physical and geometric information of the building, such as the dimensions of the structural elements, is used along with the motion of the moving parts of a machine in order to calculate the speed and distance each part travels in each cycle to complete the production tasks required to manufacture the building. The developed production estimation system can also calculate the life-usage of each part in the machine in order to support the maintenance scheduling process. The developed framework is implemented within the Autodesk Revit environment. A case study of a residential building is used to implement the proposed approach and demonstrate its features.
