ISCAR CASTLE MASTER PLAN

The building presented serious from structural movement cracks totally unclear. A witnesses control evidenced the continuous movement of all cracks and a geotechnical study revealed a worrying lack of consistency of the supporting substrate. Alongside a three-dimensional survey showed very important collapses and deformations. The evolutionary study marked some of the keys of interpretation. In late fifteenth century was attempted a reinforcement consisting of two solid cubes that far from solving the problem contributed to aggravate it. Finally in the sixteenth century the cube wall fallen was replaced and supported with a falsework formed by a central pillar in the dome.

Therefore were not evident two Initial considerations: the castle itself moved and in each construction stage did it independently. Initially in an emergency action each constructive stage was stitched and tied independently in order to guarantee that each historical wall was not decomposed by the movement, but avoiding to sew or stitch different typological walls to others, modifying their movements and thereby altering the structural running generated by it evolutionary process. The building is still under control of movements.
