摘要:As the main type of temporary structures, scaffolding systems have a significant impact on labor productivity and project cost in construction, but the ability to provide space planning assistance for construction planners is limited. This research developed a framework for resource allocation and space planning of scaffolding systems. A workspace-based multiobjective model is proposed to simultaneously optimize the number of supported tasks, labor piping productivity, and scaffolding labor input for mechanical piping construction. With the input data of scaffolding placement rules and task information from 3D models, the simulation-based approach effectively searches for the Pareto-optimal solutions. Further, analyzing procedure also assists the planners with final decision-making. As a validation, the applicability and effectiveness of the proposed model were tested through an example based on a 3D piping model. This study makes a contribution to the body of knowledge by proposing an improved scaffolding planning model from workspace perspective, which is capable of improving the overall performance of practical scaffolding planning in the preconstruction period.
