The division will now operate as Rendel Limited and will continue to focus on engineering services in the bridges, geotechnical, highways, maritime and tunnelling fields. The business was originally founded by James Meadows Rendel in the UK in 1838 as Rendel, Palmer & Tritton, and celebrated its 175th anniversary in 2013.  

Ingérop was formed in 1992 from the merger of Inter G and SEEE and is owned entirely by its employees. Ingérop employs more than 1,500 staff, with about 200 located outside France, mainly in Europe, South America, North Africa and Southern Africa.

Rendel and Ingérop have worked together on the New Europe Bridge across the Danube between Bulgaria and Romania, and on the tender design of the Mersey Gateway project.

Ingérop president Yves Metz said: “I am very happy with this merger, creating wealth for our partners and our teams. Ingérop and Rendel share the same vision of the market and the same values.”

Rendel managing director Vardy Jones said: “We have worked with Ingérop over many years and believe the mix of our services complement each other, which in turn will bring greater benefits to our clients and staff.  We are very excited about the opportunities ahead of us as part of the Ingérop group.”
