A cube-shaped mobile unit ferried on the back of a truck was placed in the historic centre of the town. It was divided into four parts, one on each side: analysis and diagnostics, information and education, open project, work and construction.
The analysis and diagnostics section performed structural, architectural and sanitary assessments of the area’s rundown buildings. The aim was to conduct a meticulous survey of the old homes. A tool was devised to produce a detailed picture of the ancient urban fabric: a special camera hung from the bottom of a hot air balloon took photogrammetric pictures, a solution that was much cheaper than a traditional aerial survey and more precise than a manual survey.
The second section – information and education – studied the many issues relating to the restoration of old city centres. It had a library and video-library, provided information on the condition of the city and local laws, on legislative tools and the various public funds available. It acted as a sort of interface between the workshop’s experts and local residents.
The section entitled ‘open project’ kept the public informed about the project’s practical and technical aspects and its activities via consultants specialised in the regulations which were in force, and with information about costs and opportunities for cost-cutting through cooperative purchasing.
The work and construction section progressed from the diagnoses of the previous stages to the actual restoration work itself. The worksite used non-invasive, compact, environmentally-friendly equipment (mobile scaffolding, low-speed electrical vehicles, zip-lines, presses and welders).
The practical side of the renovation was done without requiring the residents to move out of their homes. Once the structure itself was consolidated, cracks were filled, roofs fixed, plaster redone, humidity eliminated and new sanitation installed. New techniques were employed wherever possible, such as the use of polyurethane spray foam for thermal and acoustic insulation and injections of silicon resin to prevent humidity.
