مرمت نمای آسمان خراش پیرلی در میلان و تعمیر آسیب های وارده به سازه های بتن آرمه ناشی از سقوط هواپیما: نمونه ای از حفاظت منتقدین

The main intervention concerns the recovery of the structure with over 10,000 m2 of continuous aluminum and glass façade in a skyscraper designed by Italian master Gio Ponti and the repair of the damage to the reinforced concrete (RC) structures (designed by another Italian master, Pier Luigi Nervi) caused by a plane crash. The straightening and repair of the RC using entirely innovative methods and the conservation of the structures of the whole façade also translates into financial savings. Approximately 20% of the savings is derived from the complete substitution of the curtain wall. This idea of authenticity results in a method of restoration in which all single parts may not always be replaced for every functional upgrade. This scenario is important news, especially for modern architecture that usually prefers the value of what appears to be new, showing parts that are always perfect since the time they were built. People also consider the conservation of items that were considered as merely industrial products a few years ago.
