Retrofit &
Conservation
Seismic strengthening, structural assessment, adaptive reuse, and the engineering of existing buildings for a changing world.
The retrofit and conservation of existing structures is one of the most technically demanding and socially important areas of structural engineering practice. Whether upgrading a pre-code concrete frame for seismic resilience, strengthening a Victorian railway viaduct for modern loading, or adapting an office tower for residential use, retrofit engineering demands creative problem-solving within severe constraints. LoadBearing covers the full spectrum of this discipline — from assessment methodology to completed projects.
