A dedicated team of experts specialising in the engineering of existing structures

Engineering expertise for existing structures helps contracting authorities to manage their infrastructures and built heritage at every stage in the life cycle of engineered structures.

From the time work begins on site to the end of its life, a building or civil engineering structure must be inspected, monitored, maintained and – in most cases – reconfigured and/or upgraded. The design and implementation of these maintenance and refurbishment tasks must have their basis in special knowledge and expertise.

This type of specialist engineering is essential in responding appropriately to the complex problems involved in assessing the service levels of structures and identifying maintenance tasks to be undertaken and completed.

Against a background of increasingly restrictive budgetary and operating conditions, maintenance scheme optimisation is becoming a necessity for contracting authorities.
