Many steel truss cable-stayed bridges have been built in in China in the past two decades, providing a wealth of design and construction experience. This paper provides a review of their development, the structural configurations used, the mechanical characteristics of decks, pylons and cables, and the various innovative construction methods adopted. With main spans now exceedings 1 km, the sturdy structures are mainly used for combined rail-and-road crossings in preference to more flexible suspension bridges. The aim of the paper is to provide a comprehensive and useful reference for further design and construction of steel truss cable-stayed bridges worldwide.

In 2018, Rhondda-Cynon-Taf Borough Council initiated a project to find an innovative solution to segregate recyclable waste to meet the Welsh government’s zero-waste targets. The solution involved procurement of a state-of-the-art, highly automated recycling plant within an existing structure. Anticipating design and supply challenges, the collaborative NEC4 contract suite was adopted. This paper describes the benefits and flexibility of NEC4, especially when unanticipated challenges were encountered, as well as lessons learned.

Building information models offer significant advantages in managing existing buildings and infrastructure. If no such ‘digital twins’ exist, they can be generated from two-dimensional computer-aided design drawings or from laser scanning photogrammetry. This paper starts by describing and comparing the two methods of model generation. It then reports on a study where both methods were used to model a university building complex in Turkey. The results are compared and discussed, highlighting their respective advantages and disadvantages. It is concluded that the ideal solution is a combination of elements of both methods.

By reducing greenhouse gas emissions not only during construction of new infrastructure but also by extending the lifespan of existing assets, civil engineers play a vital role in contributing to meeting the United Nations Sustainable Development Goals. This paper focuses on how engineers in New Zealand have adopted clever yet elegant solutions to reuse, repurpose and revitalise existing transport structures in the past two decades. Case studies of road and rail bridges from Waka Kotahi New Zealand Transport Agency and KiwiRail network highlight the various challenges, solutions and lessons learned.

The current constraint on skills and knowledge across the infrastructure sector on how to set up, structure and procure digital solutions at each stage of the asset life cycle needs to be rapidly overcome to allow climate-change targets to be achieved. Digital solutions and data sharing must be given a high priority, with operating models developed and funded as part of the overall resourcing, procurement and contracting process for infrastructure assets. This paper summarises some of the practical structural and legal considerations which need to be overcome to enable digital solutions – particularly building information modelling and digital twins – to be successfully implemented to support infrastructure climate-change targets.

The new 277 km Fuzhou–Xiamen high-speed railway in China is the country’s first cross-sea railway designed for operational speeds of 350 km/h. Completed in 2023, it involved various advanced construction technologies, including the world’s first 1000 t bridge-building machine to be used offshore, advanced corrosion-resistant steel, pioneering rotation of a main bridge pylon, and aerodynamic steel–concrete composite bridge decks with ballastless tracks. The innovative project represents a milestone for China’s high-speed railway, heralding a new era of cross-sea transportation.

A new multi-award-winning development of high-rise living quarters for firefighters in Hong Kong has been successfully delivery using modular construction. Created from 3726 factory-made concrete modules, it is the first high-rise concrete building development in the region to adopt the ‘modular integrated construction’ method. This paper describes the modular construction process, the NEC-based procurement approach and the innovative technologies used in the development’s design and construction, all of which contributed to a highly efficient and sustainable solution.

Global engineering consultancy Jacobs’ has developed a new behavioural management process to ensure its built-environment designs are more sustainable. The process changes designer behaviour from focusing purely on technical and legal compliance to a culture of ensuring the health and safety people who will construct or interact with the designs at the same time as benefitting the environment, climate and sustainability. This paper introduces the process and its associated practical support tools. It then explains how it was successfully applied on part of the High Speed Two railway project in the UK.

Completed in January 2022, the 2.1 km long 12.2 m diameter twin-bore Mumbai coastal road tunnel is country’s largest ever constructed using a tunnel boring machine. It is also India’s first undersea tunnel embracing all current international design and operational standards. This paper describes Mumbai’s unique hydrogeological conditions and its impact on the choice of tunnelling machine. It then discusses the logistics of transporting the huge machine through one of the worlds most congested cities; the decisions made in its assembly, lowering and re-launch; and how overall tunnelling challenges were overcome.

Faced with a climate emergency, civil engineers need to start reducing, reusing and repurposing now. But the profession first needs to debunk its sustainability myths, say James Norman of the University of Bristol, Tim Ibell of the University of Bath and Oliver Broadbent of Constructivist.
