However, it added that it is now “going even further” in its delivery of “more innovative and complex infrastructure projects”.
The firm continued: “Our brand needed updating to reflect this evolution - representing who we are now and where we are heading to, how we truly act and why we exist.”
Meridiam chief executive and founder, Thierry Déau, said: “Today we are making a commitment to people and the planet, for today’s world, tomorrow’s progress and the good of future generations.
“This strong sense of purpose is captured in our new signature ‘for people and the planet’, in our imagery and in our new identity.”
