Accelerating progress towards Net Zero bridges

The context and need for urgent change will be familiar, and a blizzard of Net Zero initiatives has now emerged. But what does it mean for bridge clients, designers, contractors and the wider supply chain? What should be our priorities, and what can we do that is practical, relevant, effective, and immediate? The Net Zero Bridges Group was formed to encourage collaboration and work more rapidly towards change. This keynote presentation will highlight key things that you can be doing so that we all accelerate progress towards Net Zero bridges.

Innovation at height - constructing the towers for the world’s longest suspended span

Opening in March 2022, Turkey’s 1915 Çanakkale Bridge will be the world’s longest span suspension bridge. During the design phase, crane specialist Marr Contracting proposed an innovative heavy-lift approach for the construction of the bridge’s 318m-high towers. By leveraging the concept of modularisation and early client engagement, productivity and safety on site could be increased and the exacting construction programme accelerated. The heavy-lifting approach developed for the record-breaking bridge in the Dardanelles could be replicated in similar bridge projects around the world.

The 1915 Çanakkale Suspension Bridge: deck erection over the Dardanelles Strait

The 1915 Çanakkale Bridge spans the Dardanelles strait at the western end of the Sea of Marmara. More than 3km of deck were erected in two months during the summer of 2021. Eight 450t SWL lifting gantries were required for deck erection, two for each side span and four for the main span. The gantries were self-erected onto the main cables. The presentation will describe the deck erection gantries, including operation on site. It will focus on the innovations specifically developed for this project, in particular, the double tandem lifts near the towers and the self-erection system; innovative solutions which maximise pre-assembly off the critical path and minimise disruption to shipping.

Sustainable procurement – the experiences of Rijkswaterstaat

Rijkswaterstaat is undergoing a period of transformation in order to meet a number of sustainability goals over the coming years. What expectations does Rijkswaterstaat have of the contractors, and what results does it want to achieve? How do the different parties come together on this journey? And how to ensure that project outcomes are in line with sustainability goals? The presenter will share insight into the sustainability goals of Rijkswaterstaat including how the organisation has put into practice the procurement of concrete with a lower footprint, and its re-use.

Digital stone bridges for sustainable construction

The majority of the UK’s bridge stock is made up of stone arches many of which have lasted for 100’s if not thousands of years. Stone arches are remarkably resilient and require minimal maintenance meaning their whole life cost can be a fraction of other forms of bridge. Their whole-life CO2 emission and environmental impact is over 70% lower than concrete or steel, yet very few are built these days. With increasing emphasis on sustainability, revenue maintenance budgets under severe strain, and the availability of digital technology, new ‘digital stone’ bridge construction has the potential to become a real construction alternative for the 21st century. Pilot studies are being developed to demonstrate the feasibility of new stone arch bridges for suitable applications and to offer easy-to-use design and construction guidance.

Bennerley Viaduct - from rehab to iron-to-iron challenge

This is the story of a very large wrought iron Victorian railway viaduct that strides across the flood plain of the River Erewash between Derby and Nottingham. This Iron Giant recently experienced a journey that saw it transform from forgotten rusty relic to celebrated and well managed public facility, albeit still rather rusty. This project is characterised by multiple international funding sources, enthusiastic community involvement, prudent spending and sympathetic engineering intervention. With many more disused railway viaducts around the UK, it is hoped that this project might inspire the salvation of similar historic gems.

Speakers :
Kieran Lee, Community Engagement Officer, Friends of Bennerley Viaduct Paul Thomas, Asset Manager, Sustrans/Railway Paths Kevin Dentith (CHAIR), Chief Engineer, ADEPT Bridges Group and Bridge Owner's Forum

14:25-14:50

Moveable bridges, the one mechanism approach

Drawing upon ROD and H&H’s combined experience – in the latter’s case more than 225 moveable bridges in the last 20 years – the presenters will explain why undertaking design, assessment and refurbishment of moveable bridges is most effective when they are treated holistically as a single mechanism. Examples will be drawn from existing moving bridges as well new-build structures that include the Great Yarmouth Third River Crossing.

Speakers :
John Collins, Associate / Bridge Engineer, Roughan & O'Donovan Paul van Hagen, Principal Bridge Engineer, Hardesty & Hanover Kevin Dentith (CHAIR), Chief Engineer, ADEPT Bridges Group and Bridge Owner's Forum

Protecting bridges from large woody debris: a novel system of trapping devices

Large woody debris can be responsible of severe damage to bridges and cause bridge failure. A novel system has been tested at the laboratory scale and showed promising results for efficiency of debris trapping and reduced flood risk. This presentation shows the hydraulic experiments for this device carried out at the University of Exeter and the potential application to rivers, with an outlook to full-scale testing.

Decarbonisation of bridges and viaducts

An innovative project is currently under way with the UK Department for Transport that is focused on identifying carbon reduction in bridges and viaduct assets with an emphasis on whole-of-asset-life carbon management. This uses a tool that was developed by Mott MacDonald and the University of Bristol called FUTURES - Future Uncertainty Toolkit for Understanding and Responding to an Evolving Society.

Hammersmith Bridge – pedestal stabilisation

Built in the 1880s, Hammersmith Bridge is a grade II* listed chain suspension bridge, crossing the River Thames in West London. Following the discovery of critical defects to the cast iron pedestals supporting the main suspension system, the bridge was closed to motorised traffic and subsequently to pedestrians and river traffic beneath.  After detailed investigations, analysis and successful implementation of a temperature control system designed to actively moderate the loading exerted on the distressed pedestals, the bridge was reopened to all but motorised traffic.  This presentation discusses the solution developed to address the root cause and reinstate functional articulation at the seized deviation saddle roller bearings in order to permanently stabilise this Heritage Bridge.

The Golden Gate Bridge Retrofit Programme

The Golden Gate Bridge is undergoing an important seismic and wind retrofit program that will include, among other modifications, the addition of jumping deterrent nets and the replacement of structural members. To proceed with these retrofitting activities, platforms and tarps will be temporarily installed on the deck and are expected to have an influence on the sensitivity of the structure to wind-induced vibrations. Given the transient nature of the structure during this work, a strategy combining experimental methods and numerical predictions was employed to evaluate the aerodynamic performance of the bridge and to guide the construction schemes. In particular, the percentage of the length of the main span and side spans that could be tarped without negatively influencing the aerodynamic stability of the deck was determined.

Towards zero carbon steel – an insight for the bridge sector

Reducing embodied carbon in steel for bridges requires an understanding of the manufacturing process, its relationship and effects on steel products and supply chains, and how to interpret supporting data.  This presentation gives insight into where the carbon is in steel making, how decarbonisation will align with the Paris Agreement, making sense of EPD and what solutions are available today for bridge owners and designers.

11:55-12:20

Bridge tendons monitoring using acoustic emission technology

A common and recommended practice for the monitoring of civil and industrial infrastructure, Acoustic Emission technology enables the detection of wire breakages even when tendons are embedded in concrete and are relatively far from the surface, which other NDT methods cannot detect. In addition to providing examples of bridge monitoring at various stages of a project - from inception to execution and maintenance – the presentation will discuss the results obtained during tests of real wire breakages on a decommissioned bridge in Germany, where the structure was being monitored using several SHM technologies. We will report in detail about the result of AE in those trials and how it compared with the other methods tested.

Bridge impact managed by remote monitoring

Bridge impact is an ongoing problem for Transport for London. Strikes cause disruption to road and rail networks and damage to the bridges. Transport for London has employed James Fisher Strainstall to implement BridgeStrike monitoring on 11 bridges which support London Underground lines over public roads. Impact detected in the monitoring systems trigger data capture and provides evidence for keeping routes open to traffic and for prosecutions. The presentation will describe the problems faced, the monitoring solutions and how it is applied for bridge management.
