Keller (LSE: KLR) is the world’s largest specialist geotechnical contractor, quite literally preparing the ground for major construction projects. Its work has included groundworks for Zayed City, a new “downtown” area in Abu Dhabi; a tunnel at the iconic Hard Rock Casino in Florida; mining the 2,700ft long First Street Tunnel in Washington DC; building work on a drop-shaft for London’s Thames Tideway project; and overseeing work on a renewable-energy refinery for Nestlé in Singapore.

Keller’s teams of engineers are experts in geotechnical theory and experienced in a wide range of techniques, so the company can offer a service known as “project design and build”, whereby the optimum solution is first selected and then built. Some 40% of the 5,500 contracts executed each year are design-and-build schemes.
