**15. Conclusion and looking forward**

The issue of using digital capture has therefore come into its own in the modern era and in a practical sense to be able to 'bring back' the structure into a design

office to be able to discuss the problems and the practical methods that can be used to strengthen and preserve the Heritage structures (**Figures 36** and **37** for the sea wall rebuild at Les Minquiers is another good example).

However, the types and format of digital information and records need to be available to all and pooled together if possible and practical so that the various bodies that can benefit from using the visual experiences which has been captured. It should then be practically possible to not only pass on the technical knowledge but also provide a 'virtual record' of what was originally constructed from the archive research together with the visual records of how the site investigation and repair work was done. The data stored then remains as a full detailed record of what was done at a particular time to preserve these magnificent heritage structures for future generations to marvel at. This concept puts forward a new way of sharing how these unique structures have been assessed, repaired and strengthened and creates a new paradigm for Heritage Structural Preservation.
