Thanks to steady advances in computer-aided design and additive manufacturing, it is already possible today to describe and segment a range of complex structures and to manufacture them with high-performance concretes under a high degree of automation. Beyond the current, exploratory applications of these techniques, it must be possible in the foreseeable future for bridge construction to benefit from the ever-increasing flexibility and performance of these technologies. Current approaches to serial construction, however, are limited in design to predominantly conservative construction ideas and fabrication techniques and do not take full advantage of the expanded design freedom. This is largely due to the fact that the high planning effort required for this is carried out manually or is automated only in individual, unrelated sub-steps. A largely untapped potential for meeting this challenge lies in designing the entire process chain in a digitally continuous manner so that a cross-scale link is achieved from the design of the bridge system to segmentation and robot-assisted manufacturing. This significantly reduces the costs for detailing and necessary adjustments and provides the basis for being able to react dynamically to critical manufacturing and test data in order to adjust the parts of the design that have not yet been manufactured. A close coupling of the design processes with quality controlled and managed production is realised by the consistent application of cyber-physical systems (CPS).

由于计算机辅助设计和增材制造的稳步发展，今天已经可以描述和分割一系列复杂结构，并在高度自动化的情况下用高性能混凝土制造它们。除了这些技术目前的探索性应用外，在可预见的未来，桥梁建设必须能够从这些技术不断增加的灵活性和性能中受益。然而，目前的串联结构方法在设计上限于主要保守的结构思想和制造技术，并且没有充分利用扩大的设计自由度。这在很大程度上是由于这样一个事实，即这所需的高规划工作是手动执行的，或者只在个别的、不相关的子步骤中自动执行。应对这一挑战的一个尚未开发的潜力在于以数字化连续方式设计整个工艺链，以便实现从桥梁系统设计到分段和机器人辅助制造的跨规模链接。这大大降低了详细设计和必要调整的成本，并为能够对关键制造和测试数据做出动态反应提供了基础，以便调整尚未制造的设计部分。设计过程与质量控制和管理生产的紧密结合是通过网络物理系统（CPS）的一致应用实现的。
