Allplan Bridge 2019-1 features 4D construction process planning and ‘effortless positioning’ of standardised and repetitive profiles

Allplan has introduced a new version of its BIM solution for bridge construction, Allplan Bridge. The parametric software is designed to support engineers in all planning phases, from the initial concept to construction, especially for reinforced concrete, prestressed concrete and composite bridges.

The 2019-1 release contains a number of new features including the definition of the construction sequence and the positioning of standardised and repetitive profiles such as longitudinal stiffeners for steel and composite cross-sections and numerous other detail improvements.

It is also possible to map the construction process in a 4D model. The construction plan is first divided into several construction phases and then into individual tasks such as concrete hardening, tendon stressing or activating the self-weight. The corresponding components are interactively assigned to the tasks. In this way, the temporal dimension is linked to the structure and the construction process graphically visualised.

With Allplan Bridge 2019-1, it is also possible to create several different construction plans for the same bridge for a variant comparison, resulting in a parametric 4D bridge model. Once the construction is completed in Allplan Bridge, the model is transferred to Allplan Engineering, where further steps such as detailing, reinforcement and plan creation can be carried out.

“The consideration of the fourth dimension as well as the exact reproduction of the bridge construction model during the construction process form the basis for the precise, non-linear calculation of bridges.” says Vanja Samec, managing director of Allplan Infrastructure. “With Allplan Bridge 2019-1, we have set a milestone for bridge construction analysis. This allows us to combine the geometric with the analytical model.”
