Extension of Headquarter BGL BNP Paribas, Kirchberg
Volume: 360 m³ expanded clay 4-10 mm
Owner Builder: BGL BNP Paribas
Contractor: AM CLE CBL Constantini
Designer: M3 Dell Linster Lucas - SGI Engineering
Problem / Solution
The extension of the headquarters of BGL BNP PARIBAS is situated at Plateau du Kirchberg, between l’avenue JF Kennedy and la rue Steichen. The project consists of 2 buildings .
– the building JFK presents 6 levels alongside the l’avenue Kennedy, and develops a surface of approximately 17 000m².
– the building Tour goes up to 15 levels opposite the roundabout Serra, with a surface of +/- 29 700m². The total surface of the building represents 95 000m².
At this particular construction site expanded clay aggregates are used as light infill materials for embankment limits, to reduce setting and compensate loads of extra horizontal and vertical powers. Also for the building surroundings expanded clay is being applied in purpose of permanent drainage system and soil improvement.
The expanded clay is put in place in a very fast and effective way.
Why expanded clay?
The building site is not easy to access, so blowing the lightweight expanded clay from a distance of 50 m on higher levels and underground can be easily completed within minimum of time. Fase 1: first delivery 8/10/2015 by a silo truck with blowing nozzle. Still ongoing.
