Laing O’Rourke have been working on a project to develop a set of design configuration tools for bridges. The tools will create a smoother digital process for the design, manufacture and assembly of bridges, reducing the time it takes to complete a bridge.
Laing O’Rourke chose to develop the tools using SOLIDWORKS and DriveWorks, to automate the manufacture of a set of standardized, validated parts and sub-assemblies for the most common bridge types.
They recently showcased the tools at a dissemination event.
The event was held at King’s College in Cambridge University, where Scott McGovern, Digital Engineering Leader at Laing O’Rourke talked about the project. The event gave the team the opportunity to review and gather feedback on the tools, their capabilities and the development process to date. They also reviewed the research they have conducted and the impact of digital technologies on the construction industry.
The event showcased how DriveWorks is being used to transform the design process for an entire industry.
The project was set up to develop a unified digital delivery process for the bridge industry. The project configures bridge designs from a set of key inputs and a library of parametric components.
The output is a fully coordinated 3D model, with a pack of data generated automatically alongside it. The data pack contains bridge methodologies, and cost and programme data – a single source of truth for the whole bridge lifecycle.
This is the first time a project of this scale, with this much potential for efficiency, has been attempted in the industry.
The project uses standards to simplify bridge processes and reduce the time it takes to complete a bridge. Currently the design process is complex, for a single span 30m bridge it takes 32 weeks (excluding approvals). The construction of the same bridge then takes a further 66 weeks.
By digitising bridge design with this project, Laing O’Rourke have identified savings that could see bridge designs produced in days or weeks instead of months and years. Rolling out the project will increase efficiency and capacity across the entire industry.
The process for designing bridges changes often as most bridges are bespoke. They are designed by different consultants in slightly different ways, rarely enabling the benefits of offsite manufacture and rapid onsite construction.
The key focus of the project is about creating a common standard, synchronising data and protocols. The aim is to improve interoperability between different parts of the bridge building process.
The project integrates best practices for manufacturing, assembly and design, to ensure consistent data formats and eliminate any manual processes between stages.
For this to happen, naming conventions and output files from each stage of the process need to be structured and arranged in a systematic way. Using DriveWorks, Laing O’Rourke can specify rules to determine how and where each file is saved.
They knew they couldn’t focus on everything initially. Instead they looked at the base components for bridges, which can be assembled in a variety of different ways. To ensure a standard across the industry, the project enables them to define the components, select them and combine them in the original design.
DriveWorks software is modular and scalable so for every DriveWorks project, we recommend companies ‘start small’ and add to it over time. Even at this scale, Laing O’Rourke have recognised this is the best practice.
Eventually, the project will cover all aspects of designing bridges and the research delivered could also inform the processes for other parts of the construction industry too.
