A bridge axis is created or imported, and the cross-sectional geometry either designed or taken from a template (Figure 2).

A Tailored Modeling WorkflowĪ similar modeling approach to the conventional bridge modeling process is used at first. With just one bridge model, an entire BIM-supported bridge design process can be carried out from within this parametric design solution. The latest version includes new features that provide an updated modeling workflow, so that precast girder bridges can be created with ease. © ALLPLANĪllplan Bridge - a complete, integrated BIM solution for bridges - has been recently updated to address this need. Because girders are straight, their geometry is not directly impacted by the road or bridge axis. That is why precast girder bridges require a different modeling approach.įigure 1. Similarly, their final position on the bridge is dictated by the geometry of the supporting substructure. The straight profile of precast girders is why their geometry is not directly impacted by the road or bridge axis (Figure 1). While there are different types of precast girder bridges, they all have one thing in common - their component geometry. In addition, the economy and high quality of prefabricated girders creates savings for transport authorities while minimizing the environmental impact and disruption to the local area during construction. The rapid erection enables contractors to work on more projects simultaneously and poor weather conditions have a minimal effect on the construction schedule. Because precasting eliminates many on-site, in-situ work processes, construction time and costs are reduced, and quality is improved. Precast concrete bridges have been in use since the late 1950s and are commonly used for highway bridges. Precast girder bridges are one example of this, as their geometry is only indirectly governed by the axis. As bridges come in many types and each requires different construction methods, some require a different approach to modeling. However, most modeling techniques are particularly suited to bridges whose geometry is governed by the bridge axis or alignment.

Nowadays, ALLPLAN GmbH is a leading European supplier of open BIM (Building Information Modeling) solutions.Īpart from CAD software for architects and civil engineers, Allplan provides facility management solutions, and also the NEVARIS software for construction cost management. Nemetschek Allplan GmbH was founded in 2008, and was then renamed as ALLPLAN GmbH in 2015. In 1981, this became Nemetschek Programmsystem GmbH, which launched the first version of our CAD solution, Allplan, on the market in 1984. As a CAD pioneer, Professor Georg Nemetschek founded the Engineering Office for Building and Construction in Munich in 1963.
