Pierre Engel, Chief Project Engineer of the ArcelorMittal Orbit, is responsible for ensuring the construction goes smoothly. He has a lot on his plate. No other building like this has been constructed before – as a sculpture, the structure is completely asymmetrical and every line of it is curved. Is it also the first time a 115-metre high building has been assembled without scaffolding. Pierre must enforce high safety standards and ensure every stage of the construction is completed on time and with absolute precision if the ArcelorMittal Orbit is to be ready in time for the Olympic Games.
