Dismantling steel cantilever truss bridges is a complex operation that requires significant engineering to produce safe and effective dismantling sequences. Such sequences often include a variety of temporary works including temporary truss members, temporary support towers, tension-release devices and temporary attachments for heavy-lift components. This paper provides a review of the design and analysis considerations for developing a dismantling sequence for cantilever steel truss bridges and the design of required temporary works, with three examples from the USA.

Building information modelling (BIM) is both a digital modelling method and information integration platform for interoperability in the construction industry. This paper reviews the concepts and features of BIM along with its different meanings, historical evolution and data exchange standards. It then analyses its application in the Chinese construction industry, with examples of recent major projects. It concludes that many civil engineers are still unable to use BIM to its full potential due to implementation complexity and the industry’s fragmented production structure.

Wufengshan Expressway, which opened in June 2021, is China’s first intelligent highway. Its smart systems include 5G communications, wireless chargers, artificial intelligence, the ‘internet of things’ and the ‘internet of vehicles’. The use of these technologies has improved operational efficiency, safety and management. It has also helped to reduce greenhouse gas emissions and protect the environment. This paper study introduces the various systems installed on the new road and will serve as a reference for future intelligent highways.

A 183 t conical concrete roof of a cylindrical anaerobic digester tank at a UK sewage treatment works had to be lifted 150 mm to repair the seal underneath it. Due to limited space for a crane, an incremental hydraulic jacking procedure was used, with 32 bottle jacks in pockets cored out from the top of the concrete tank wall. This paper describes the temporary works design methodology, the extensive planning for risk mitigation, the practical implementation strategy and the lessons learned from using this safe and cost-effective approach.
