BIMsite - Towards a BIM-based generation and evaluation of realization variants comprising construction methods, site layouts and schedules

Despite the proliferation of BIM tools in construction process planning, the BIM-based development of a digital representation of the construction phase, including detailed site layout plans, is still in a very early phase. Most planners still use manual methods and rely on experience when it comes to the selection of construction methods and site layout planning. The following paper introduces BIMsite, a recently started research project, focussing on BIM-based site layout planning under the consideration of different construction methods. The project investigates how to generate different variants of construction site layouts based on different construction methods in a semi-automated way; and how to evaluate those variants utilizing construction simulation approaches. The paper provides an overview of the initial research, focussing on first approaches regarding construction site generation, optimization and simulation.
