The site control during construction and the on-site investigation for the diagnosis of the state of conservation of existing masonry building were the subjects of the workshop. For the above mentioned type of investigations no standards or code exist on procedures and testing. The scope of the RILEM TC 177-MDT is the preparation of recommendations and guidelines for the use and application of non-destructive techniques to be applied on-site for the control of new masonry structure construction and for the diagnosis of historic masonry structures.
This workshop had the aim of bringing together international experts to scrutinise and consolidate the state-of-the-art in the site control and NDT (non-destructive techniques) applied to contemporary and historic masonry buildings.

The presentations were divided into six sessions as follows:
1) Site control on materials and workmanship
2) Structural monitoring of exiting buildings
3) Non structural monitoring systems
4) Minor destructive techniques (MDT)
5) Non-destructive techniques (NDT)
6) Complementary use of tests and case history

Active discussions were developed around the limits and advantages of the site ND evaluation of masonries.
The Workshop clearly reached the goal of confirming the advanced preparation of the TC members but also to enlighten the need of dealing with some topics as monitoring and use of thermography and of simple site tests.
