assembly was planned for December (wintertime in Ita ly). The possible loading conditions related to the weather have required to put a specia l attention to the stability of the intervention; furthermore, the intervention was planned together with the municipa l administra tion . In this case, therefore, it was not an “underground” and spontaneous initia tive, but it had to be doneaccordingwith the existing roles for temporary structures. The need to comply specific technica l requirements evidenced a serious lack of roles for these cases; in fact, there were not ava ilable instructions for procedures compatible to the case-study. The requirements provided by the Tuscan Government, i ndeed, were not suitable to be adopted. As a result, a further “actor” was involved in the process, i.e. an engineer specifica lly skilled in temporary insta llations. Despite his intervention, however, there has not been a positivesolution of the problem, and the intervention has never beencompleted. This experience has evidenced a lack of opera tive roles to perform non-conventiona l interventions in the respect of the lega lity; in the following this experience has been described, and the inconsistencies of the technica l legisla tion in this ma tter have been evidenced. 2. Planning anddesign 2.1. The old industrial center in Novoli Novoli is a district of Florence which developed in the middle of the XX Century (Biagi 2008). At the end of the 30s, an important industria l building was made in this area for the FIAT company, according to the project made by the architect Vittorio Bonadé Bottino (Signorelli 1988). Few years after the beginning of its construction, the company moved its headquarters from Florence to Turin, which became its officia l location. The industria l complex, anyway, was constructed (see Figure 2a) , thanks to a specia l agreement with the “ Società Anonima ” of Florence. With the urban development occurred after the WWII , the industria l complex represented a barrier for the expansion of the town. The most part of the buildings constituting the industria l complex have been demolished in the last decades of XX century, whilst the power station (shown in Figure 2 b,c) has been left as a symbol of the former arrangement of the quarter. In these last years, the quarter has been largely developed, becoming the most modern pole of the town. The building is surrounded by modern devices, such as the metro -line, inaugurated in December 2018, a shopping center and an urbanpark.

2.2. The Power Station The Power Sta tion is a tower-building; it has a squared plan with the sides of about 20m, and a globa l height equa l to 31 m, besides a chimney 50-meters ta ll. It has two interna l floors only, respectively at the levels of 5m and 22m. There is another open floor, a perimeter ga llery, a t the height of 27m, 4 meters belowtheplane roof.
