Vertical extensions: technical challenges and carbon impact

Tim Chapman and Ian Firth highlight the carbon differences between civil structures and buildings projects, and propose that engineers work with their clients to target low-carbon outcomes, rather than just low-carbon structures.

This article describes the structural reuse and strengthening strategies adopted to enable three additional storeys to be added to an existing office building in London.

Will Hawkins, Angus Peters and Tim Mander argue for designers to challenge overspecification and grasp the opportunity that reduced floor loads offer for low-carbon structural design.
