Hochtief UK has appointed Lawrence Jackson as its new managing director.
Former MD Sally Cox has stepped down after two years in the role.
Mr Jackson has been with Hochtief for more than 20 years, working on infrastructure projects in Europe, Africa and the Far East.
He also formerly ran the South African branch of Hochtief.
Hochtief was one of the firms to miss out on the civils contracts for High Speed 2, as its joint venture with Dragados and Galliford Try failed to secure any of the seven works packages.
The company is also bidding for the Silvertown Tunnel under its Hochtief PPP Solutions UK brand.
Mr Jackson said: “I look forward to working with the Hochtief UK management team to build on the many successes of recent years and to continue delivering engineering excellence, innovation and value for our clients and the communities we jointly serve.
“Our focus will remain firmly on our current projects and the pursuit of new opportunities in line with our strategic growth plans, including bidding for the Silvertown Tunnel project for which we and our joint venture partners prequalified in March.”
Riku Tauriainen, MD of Europe West for Hochtief Infrastructure GmbH and board member of Hochtief UK, said: “We thank Sally for her valuable contributions to the company and wish her every success in the future.
“Having run the Hochtief South Africa branch and with considerable international infrastructure experience, Lawrence is extremely well placed to further build on Hochtief’s strong financial and technical position in the UK with the many opportunities ahead.”
