3D printing innovation has transformed product design. Today, the process is being used to build larger structures in order to alter the way we think about construction.

Fremont, CA: Technology and engineering are inextricably linked. They rely on one another to advance innovation in all sectors. Technology has enabled bridge designers to push the boundaries of what was previously thought possible.

With the help of technology, new designs and improved maintenance services increase efficiency and reduce waste. While some innovations are making their way into the mainstream, others can provide insight into the future of bridge engineering. In this article, we examine the most promising technology that is shaping the future of bridge construction.

Building Information Modelling (BIM)

While digital constructions are common in bridge engineering and the construction industry as a whole, increasing digital capabilities are changing the way structures are built collaboratively.

Engineers can now design structures for reference and measurement using computer-aided design (CAD). However, newer BIM programming allows workers from all stages of the construction process to contribute their ideas to improve workflow.  

BIM can render a model with specific detail for each industry involved, from design to construction and manufacturing, by calculating layers of metadata.As a result, problems such as clash detection and stability can be solved early in the design process. Increased efficiency will also aid in cost savings.

3D Printing

3D printing innovation has transformed product design. Today, the process is being used to build larger structures in order to alter the way we think about construction.

This technique is still in its early stages for bridges, with the first 3D-printed bridge being completed in Madrid in 2016. The crossing over a small river was built using additive manufacturing, which involved layering concrete.

However, the technique can be used to add strength to a variety of materials, including steel.

The benefits are becoming more apparent as technology advances. For starters, it can reduce the amount of cement and steel needed in construction, lowering costs and emissions. 3D printers also do not require formwork, which eliminates waste. Finally, it implies that bridges of any shape can be constructed.
