ABSTRACT

The condition of underlying rock and footing masonry affects significantly technical condition of historical monuments. The caused subsidence may affect the origin of construction cracks, which may directly influence its stability. These impacts are mostly indirect and they are difficult to identify due to information lack. Footing masonry and long-term changes in the underlying rock are hidden underneath existing ground and floor level. If records related to foundations do exist, they are frequently fragmental. Monitoring can be source of information due to direct outputs and data describing footing masonry and subsoil conditions. Examples of monitoring instrumentation and gained results, determination of conditions of masonry together with principles of monitoring applied in the project focused on the Broumov Group of Churches are presented in the paper. Within the monitoring instrumentation, Fibre Bragg Gratings monitoring technology has been used and is described in the paper as well.
