The utilisation of drones in bridge inspections signifies a significant advancement in engineering practices.
- At the recent NCE Bridges conference, Taylor Woodrow described transformative methods for conducting bridge inspections.
- Drones are enabling faster and more precise data collection compared to traditional inspection techniques.
- Automation and digital interfaces contribute to efficiency and safety, reducing the need for manpower in challenging environments.
- Future cost savings from drone deployment overshadow initial investment concerns.
At the forefront of bridge inspection technology, Taylor Woodrow is pioneering the use of drones, marking a significant transformation in engineering practices. During the NCE Bridges conference held on 18 July, Matthew Hyett, Taylor Woodrow’s digital engineering manager, elaborated on how these innovations represent a ‘step into the future’ of bridge management. By harnessing the capabilities of drones, the company has been able to revolutionise principal bridge inspections, significantly cutting down on time and costs involved.
Drones have been a fixture in the construction industry for some time, and Taylor Woodrow is leveraging their unique skill set to enhance bridge inspections. Working in collaboration with Essex Highways and Ringway Jacobs, Taylor Woodrow has captured vital data across numerous structures, using drones to target specific areas of interest on bridges. This remote inspection ability enables them to acquire detailed imagery without the need for drones to be in close proximity, thanks to advanced zoom functionalities, which ensure clarity and precision.
The subsequent processing of drone-acquired imagery aids engineers with a streamlined interface to review, identify, and address defects and concerns efficiently. Matthew Hyett emphasised the benefits of this digital evolution, noting the enhanced quality of imagery compared to previous methods and stressing the pioneering nature of these techniques in processing and utilising drone data. This approach helps flag potential issues comprehensively for timely interventions.
In high-pressure scenarios, such as rapid data acquisition requirements in inaccessible areas, drones prove invaluable. Hyett recounted situations where traditional methods would necessitate a complex array of human operators and equipment, which drones could bypass effortlessly, thereby avoiding disruptions, conserving resources, and eliminating safety risks. The use of drones, incorporating light detection and ranging (LiDAR) technology, is instrumental in developing accurate models of bridge structures without endangering inspection crews.
Despite upfront costs, the long-term financial benefits of implementing drones are substantial, reducing the need for extensive manpower and infrastructure. While regulatory restrictions in the UK pose some operational challenges, the reduction in risk to personnel and operational simplicity render drones a pragmatic choice for bridge inspections. This highlights the shift in industry practices towards more sustainable and safer inspection methodologies, with a consensus among inspectors from various clients aligning with this forward-thinking vision.
Drones are redefining bridge inspections, ensuring safer, faster, and more efficient processes that adapt to future needs.
