The paper describes the application of optical fibres for the structural monitoring which may be undertaken to establish the long-term of structures, components of construction and building materials. Condition monitoring is also used in repair and strengthening works. Examples of determination of strain, temperature and moisture content have been given. Two interesting examples of measurement using fibre optic technology were the monitoring of an actual bridge in Norway, subjected to controlled loading conditions, and tunnel deformations during the construction of a subway system in Japan. The presented results shows that the monitoring process using optical fibres has a great potential.
