The three firms have been amalgamated and rebranded under the Balfour Beatty Ground Engineering (BBGE) banner.
Joining Perry on the BBGE board will be Pennine managing director Arwel Williams who becomes head of international operations and Branlow managing director Paul Woodfield who is now in charge of business development.
A BBGE spokesman said no job cuts were made during the merge but around 20 redundancies across the three firms were made late last year.
The rebranding will mean the three famous piling names will only exist on rigs with all new deals being carried-out under the BBGE name.
BBGE Managing Director, Graham Wren, said: “BBGE combines the strengths of our existing businesses Stent, Pennine and Branlow. Whilst these companies have successfully grown by focussing on their core techniques we appreciated that an integrated ground engineering service could only be achieved by pulling the companies together and merging into one business.
“By working together as a single team we are in a much better position to streamline our processes and provide our customers with the right ground engineering solution each and every time.”
