Construction of an office building
CIT Blaton was entrusted with the construction of Orange new corporate headquartes. In particular, this major project stresses the importance of sustainable development in construction. With a total surface area of approximately 47,000 m², it is composed of 3 levels of underground car park, a ground floor with reception hall, conference room, kitchen and restaurant, 5 levels of offices and a technical level.
The project had to be completed within a particularly short deadline (20 months) given the scope of the works. The building has a footprint of 100 m by 70 m for the underground levels and 80 m by 60 m for the superstructure. Work in two shifts and on Saturdays was required to meet deadlines. Likewise, prefabrication was maximised: hollow-core slabs, prestressed trusses, round and square columns on several levels, prefabricated acroterion wall, etc. The heaviest and bulkiest elements were even prefabricated on site. The worksite was divided into 4 areas, which operated almost as four independent building sites at different stages of advancement.
