The rename completes the process of establishing a wholly standalone £200m contractor following its sale by Osborne Group to Sullivan Street Partners in September 2021.
The new name builds on a legacy of over 50 years of experience and expertise in civil engineering, including 30 years specifically focused on transport infrastructure solutions.
Richard Sanders of Sullivan Street Partners said: “Octavius will now be the best of Osborne Infrastructure combined with progressive commitments that weren’t possible in the recent past; Zero Carbon, lean engineering approaches, increasing levels of diversity and sustainability will be key for us as a team going forwards.”
