Darren Wickins replaces former MD Tim Smith who has left the company after less than two years at the helm.
Wickins joins from rival Silverdell where he was estimating director.
He has more than 18 years of experience in the sector including stints at Clifford Devlin and Keltbray.
Wickins has experience in delivering £50m plus contracts in the defence, banking, transport, nuclear, leisure and public sectors for clients including Skanska, Lend Lease, Sir Robert McAlpine, Land Securities, Mace, Costain and Carillion.
Keltbray Group Managing Director, John Price, said: “We’re pleased Darren has decided to return to Keltbray to develop the Pectel business and bring a strategic approach to new markets and help unlock areas outside of our existing commercial streams for revenue generation.
“Darren has a results-driven track record within this sector, and we’re delighted to have him on board.”
