He takes over as managing director with immediate effect.
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.

“With the iconic new Queensferry Crossing about to open in Scotland, the North Yorkshire Polyhalite Project commencing, numerous successful mid-sized projects and the backing of Hochtief Infrastructure, we have an extremely strong basis on which to build in the UK.”

“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.”
