Augmented Reality (AR) can create a live visualized design and analysis system of adjustable geometry regarding structural analysis and site conditions. In contrast to conventional methods, the aim is planning directly in situ to generate desirable geometry for different constructions. By considering the potential of Augmented Reality (AR) through a bridge example, the current study proposes a step-wise algorithmic approach for live planning. In this regard, using AR glasses, the site environment is initially scanned to create a basis for planning, which enables allocating the controlling and supporting points as holograms. Then, the algorithm configures the geometry of the initial bridge, minding the arch line, and a parametric cross-section is calculated. By the user interface, the on-site operator can adjust all geometrical parameters (e.g., span, height, and section). The simultaneously visualized bridge geometry and calculation results (diagrams in the natural environment) enable the operator to design optimum geometries regarding the structural and architectural criteria. Furthermore, some more details and calculations, including the construction process (e.g., the segmentation) and the financial measures (e.g., the material amounts), were also considered. In addition to designing optimum geometries, in situ planning can quickly identify geometrical problems, accelerate the process, and make a 3D model of the structures in the natural environment. The successful operation shows that this closer link between digital planning and actual construction states in further steps can be applied to different, more complex structures with a higher element number.
