With a spire reaching a height of 200 m, the Incity Tower is one of the tallest in France. A symbol of the transformation of the city of Lyon, the project has successfully met a social challenge by keeping nuisance from the site to a minimum, and also an environmental challenge, because it is the first French city-centre HQE® tower applying for the BBC and BREEAM® Excellent labels. The project is also technologically innovative, requiring the use of cutting-edge technologies including a climbing formwork system, guided facade protection and high-performance concretes, an helicopter to set last elements of the spire.
