A new underground triple escalator has been provided at Bank Station in London as part of a major capacity upgrade project. Unusually the inclined excavator tunnel was excavated uphill rather than downhill due restricted access. Using a sprayed concrete lining and no pilot tunnel, it was a first in the UK for a triple escalator. The new escalator intercepted several existing structures which had to be backfilled and then broken out, some just 0.5 m from operational Tube lines. This paper sets out design considerations, construction sequence decisions, operational risk management and discusses the existing assets’ response to uphill tunnelling based on a comprehensive monitoring scheme.

Remote-working and other innovative technology developed during the Covid-19 pandemic is now helping the civil engineering and wider construction industry to save money and create new high-value, data-driven jobs. In the UK this is being driven forward by bodies such as the Construction Data Trust and Project Data Analytics Taskforce. This paper explores how data has empowered the construction sector during Covid-19 and the role of the industry in harnessing this work for future collective benefit in a post-pandemic recovery.

Current project experience in Africa points to spatial data as a key area for improvement across the continent. This paper focuses on practical implementation of spatial data governance on infrastructure projects in Africa, using examples from ongoing projects in Kenya and Malawi where challenges have been met and solutions found. The experience gained on these projects provides an insight into three key goals to make data work for projects: maximise value from the data available, preserve that value for future users, and identify data gaps both for work now and work in the future.

Motorcycle taxis have rapidly expanded throughout sub-Saharan Africa, providing many with affordable improved access to essential services. This paper reports on a project in 2021 to convert footpaths into motorcycle taxi tracks in central Liberia. Its community-based approach was documented in a manual to train future contractors in both the technical and social dimensions of track construction. The construction methodology is presented and discussed. It gives governments and donors a unique and significant opportunity to address isolation, improve the livelihoods of rural people and create more employment opportunities for Africa’s young population.

This paper describes the new 600 MW Karuma hydropower project in Uganda, which was completed in 2022. More than 70% of the project’s structures were built underground to enhance resilience. Complexities relating to structural analysis and design, advanced engineering technologies, climatic considerations, deep excavations and tunnelling are presented. Key challenges experienced during construction, remedial measures undertaken, lessons learnt and a proposed post-construction renewable energy option are also discussed.

This paper sets out the approach, solutions and lessons learnt designing sustainable and resilient water and energy infrastructure for the Rwanda Institute for Conservation Agriculture. It showcases the role that decentralised infrastructure and nature-based solutions can play in addressing the demand for infrastructure and food security. It argues there is a need to design for both current and future uncertainty, and to work with and protect the environment. Finally, it discusses the role of two-way knowledge sharing between international and local partners to build and benefit from capability across the project team and ensure appropriate solutions for the context are adopted.

This paper reports on a study to assess the potential for future offshore wind energy in the coastal countries of eastern Africa. It identifies the areas that could host offshore wind turbines with depths smaller than 50 m and average wind speeds greater than 8 m/s. The study revealed a capacity of 98 GW of untapped offshore wind power potential in eastern Africa, a supply that would be sufficient to meet almost 60% of today’s energy demand of the whole African continent. The study proposes a politics- and geography-based path to be followed for the offshore wind energy development that can assist with future energy policy and planning, which could have an impact in the African population.

Rochester Bridge consists of two road crossings and a services bridge across the tidal River Medway in Kent, UK. A challenging and comprehensive refurbishment of all three structures was completed safely and on time in 2020, to a very high quality and under budget. Furthermore, greenhouse gas emissions were fully offset by a new mixed woodland of 8,000 trees and ongoing routine maintenance has been redesigned to achieve net zero emissions. This paper describes the planning, procurement and delivery of the refurbishment, including its focus on quality, safety, sustainability, minimisation of disruption, ease of future maintenance and promotion of civil engineering.

Finham ‘gas-to-grid’ project near Coventry, UK produces renewable bio-methane from the biogas generated by anaerobic digestion of wastewater sludge. Completed in 2021, the plant now exports bio-methane to the gas grid, contributing to ‘decarbonisation’ of gas supply and helping to deliver water utility Seven Trent’s 2030 net-zero-emissions goals. This paper focuses on the innovative solutions adopted to maximise production of bio-methane, the plant procurement and delivery process, and the challenges of Covid-19, Britain’s exit from the European Union and site-specific constraints.

Community engagement with civil engineering is essential to deliver the United Nations sustainable development goals and to address ‘wicked’ problems such as climate change. This paper explains how the Institution of Civil Engineers developed its statement of Principles for Community Engagement with Engineering to underpin best practice across the infrastructure project lifecycle. The principles are intended to be adaptable to suit a range of contexts, sectors and scales of project, and to support civil engineers at different stages of their career and levels of influence. They provide a foundation for further development of best-practice case studies and guidance, to be shared through civil engineering education and professional development.
