The design and construction of the facilities for ITER represents one of the most exciting and challenging projects in Europe at the present time. To deliver this massive programme will require the skills, experience and sheer strength of a substantial organisation. Four of Europe's largest and most respected engineering companies have joined forces to offer F4E such a world class organisation. Through this collaboration a new joint venture named "ENGAGE" has been created.
The partners in ENGAGE are:
