Building Information Modelling (BIM) technology has been widely used in the construction industry in recent years. However, to date, it still cannot sufficiently meet the requirements of construction practitioners in terms of the layout design of floor tiles. Recently, the BIM-based Parametric Design (PD) platform has presented considerable potential in automatically generating and optimizing floor tile layout design. In this paper, we propose a workflow to generate and optimize the layout design of floor tiles globally. To develop the workflow, we first formalize the design algorithm of floor tiles according to the trade know-how cutting and planning rules. Then, we combine the design algorithm with an evolutionary algorithm (EA) to generate and optimize the layout design for floor tiles automatically while minimizing material wastage. A prototype system is established in the ArchiCAD (BIM) and Grasshopper (PD platform) software. An apartment room tiling layout is used to demonstrate the feasibility and effectiveness of the proposed approach. Compared with the existing design methods, the proposed approach (1) reduces the material waste rate by 14.58% and 11.46%; and (2) improves the calculation efficiency and reduces the required computation time by 17.3 s to 50.0 s. Moreover, this research improves the existing design algorithm, enabling the BIM- and PD-based approaches to be used reliably in optimizing floor tile planning with arc-shaped boundaries. The outcomes are summarized in order to provide valuable insights in terms of floor tile waste reduction for further sustainable construction practice.
