Bridges 2024 Conference Programme
Wednesday 13 March 2024
Introduction to Event Charity
Keynote 2: Transition to Second-Generation Eurocodes – What to Expect and When
- Background to the evolution of the Eurocodes
- Timetable for the transition to the second-generation standards
- Overview of key changes for bridge design
Keynote 3: Extreme Weather Events and the New Normal – the New Zealand Experience from Cyclone Gabrielle
- On 12 February 2023, Cyclone Gabrielle reached New Zealand and over the following two days caused widespread damage especially on the East Coast of the North Island.
- With heavy rain (up to 316mm in 24 hours, compared to an annual average of 1000mm) and winds (up to 150km/hr), resulting in major flooding, land slips, damaged homes, over 10,000 displaced and over NZ$2B in damage.
- This presentation will focus on the damage to both the Waka Kotahi New Zealand Transport Agency and Local Authorities bridge network, highlighting the scale of the damage and influencing factors, the response directly after the event and the days/weeks that followed, an overview of risk and resilience and concludes with the efforts to reconnect communities and the upcoming rebuild.
Bridge Management – a Heritage Railway Perspective
- Heritage railways contribution to the UK economy
- Management of assets on a heritage railway
- Inspection, assessment and maintenance of heritage railway bridges
Exhibition & Networking
- As part of the Bridges Conference programme, the organisers of Bridges 2024 have once again linked up with the Bridge Owners’ Forum and ADEPT to host a TEN/20 (aka Pecha Kucha) fast-paced session comprising mini presentations that would not necessarily warrant a full conference presentation slot but are nevertheless relevant and of interest to the bridge community.
- The session is open to exhibitors and delegates from local authorities and academia to deliver mini-presentations on bridge-related developments.
Importance of Inspections and Bridge Inspection Manual Update
- Importance of inspections:
- Data driven agile asset management
- Prolonging the service life and safety of bridges
- Sustainability-oriented maintenance management
- Update on project to revise the current manual:
- Recent changes in focus on inspections and asset data
- Use of technology for inspections and delivering consistency
Aerodynamic and Climate Engineering Consulting to Address Climate Resiliency in Long Span Bridges
- Long span bridges must be designed for climate resiliency. For new bridges, this can be done based on historical records and long-term predictions, whilst for existing bridges, rehabilitation may be needed to ensure safe operation and increased lifespan.
- Bridge monitoring, wind tunnel aerodynamic studies and numerical analysis can help evaluate the current state of the bridge, as well as components such as the cables, deck and hangers.
- By combining this understanding with site-specific wind and climate models, digital models can be created to predict responses to future windstorms and to inform design and rehabilitation decisions.
- Case studies will be used to demonstrate examples where early-stage consulting has benefitted both existing and new bridges.
Bridge Maintenance and the UNSDGs
- How can the management of bridges relate to the UN Sustainable Development Goals?
- What actions can we take in our everyday role to make a difference?
Exhibition & Networking
Carbon Reduction in Temporary Works
- Is the embodied carbon associated with temporary works and construction (A5 lifecycle module) significant?
- Typical temporary works for bridge construction and their contribution to embodied carbon.
- How to decarbonise these items, including by making temporary works permanent.
Disruption and Carbon: Drivers to Innovation in Bridge Management?
- Bridge closures for maintenance and renewals can have carbon costs far larger than the materials used in the work.
- Innovation can improve the way we carry out renewals and strengthening, and minimise the environmental and economic impacts of bridge management.
- Case studies of innovative techniques past and present will illustrate the transformative way we can manage our vital links.
New Layout Optimisation-Based Analysis Methods for Masonry Arches
- Briefly review existing methods of analysis for masonry arch bridges.
- Outline the new ‘Thrust Layout Optimization’ (TLO) analysis method, which overcomes issues associated with traditional thrust line analysis.
- Explain how the ‘Discontinuity Layout Optimization’ (DLO) method can be extended to identify 3D failure modes in arches.
- Compare these methods with other fast-running analysis tools.
Bridge Diagnostics Using 3D Photogrammetric Survey
- 3D photogrammetric survey is a transformative tool for bridge management.
- A key part of its potential is in enabling detection and diagnosis of defects and forensic analysis of failures.
- Effective diagnosis requires different tools than provided in typical survey software.
- Our Reveal 4D software is designed to support this diagnostic interrogation of 3D surveys.
- The talk will demonstrate how simple but powerful tools allow the engineer to draw insight from surveys.
Closure of Menai Suspension Bridge: the Issue, Emergency Works, and Permanent Solution
Following a reduction to a 7.5t weight limit on the Menai Suspension Bridge in 2022, further analysis of the hangers was undertaken on Telford’s iconic structure, to identify how failure of an individual hanger socket would affect the structural integrity of the whole bridge.
This analysis revealed that in the event of a hanger failing in service, the majority of load would transfer into adjacent hangers and for all traffic load models had the potential to cause catastrophic failure of the entire deck.
This talk discusses the details of the project, including the analysis, temporary works solution employed to re-open the bridge, and details of the new permanent hangers currently being manufactured in Switzerland.
Collaborative Reporting for Safer Structures (CROSS)
- An introduction to confidential and voluntary safety reporting and CROSS.
- A brief history of the development of CROSS and its mission.
- Examples of CROSS Safety Reports and how lessons learned are shared.
- Examples of CROSS Safety Alerts, including, Reinforced Autoclaved Aerated Concrete (RAAC).
- How to become involved and contribute.
Thursday 14 March 2024
Ethics and the Engineer
- What do we mean by ethics?
- Collapse of Carillion
- Bad justice
- The five R's: reduce, reuse, repair, recycle, recover
- Modern-day slavery
Exhibition & Networking
Reducing Carbon in Bridges – from Planning to Execution Following PAS 2080
Incorporating the Digital into Bridge Asset Management
- The transition from paper based bridge asset management to Excel was considered to be a major breakthrough, when it occurred over 30 years ago.
- With developments in computing power, digital twins and artificial intelligence, we should be in a utopia of digital asset management.
- Unfortunately there are still horror stories of millions being wasted on clunky digital “solutions” are still occurring.
- This workshop session will present an overview of the opportunities and challenges relating to the implementation of a digital bridge asset management system, asset owners experiences, introducing digital twin maturity levels, and examples of successful development and implementations of fit for purpose solutions using proprietary software packages.
- The workshop will also have breakout sessions for the attendees to discuss and consider the different topics, with the aim to better understand the benefits of incorporating digital solutions within a bridge asset management context.
