proximity to sensitive locations such as power substations and buried gas pipelines, all of which were vulnerable to ground movements. In response, Keller employed advanced geotechnical techniques, including bored piles as large as 2.18 meters in diameter and reaching depths of up to 50 meters in soft marine sediments. The project’s complexity was compounded by its tight schedule and the need to operate near live rail systems and busy traffic. Despite these constraints, Keller’s experienced team successfully delivered the project on time and without incident, demonstrating their expertise in managing high-risk projects in dynamic environments. The success of this project underscores Keller’s ability to execute complex heavy foundation and earth retention solutions in challenging conditions, including the need for creative, site-specific solutions that prioritise both safety and efficiency. Keller’s approach to every project reflects its ability to innovate and adapt. The company offers a broad spectrum of techniques tailored to meet the specific requirements of each project. Whether they are providing ground improvement, piling, or other geotechnical solutions, Keller’s technical expertise and equipment enable it to take on projects of varying scale and complexity. For instance, a recent project required Keller to integrate multiple techniques including CFA piles with jet grout infills and bored piles under polymer to deliver the optimal geotechnical solution for the basement of a large commercial development. This project, located in a densely developed urban environment, demanded Keller’s deep understanding of geotechnical behavior and construction dynamics. Allan emphasises the company’s flexibility: “We can offer multiple techniques in any given project to deliver a full solution, rather than just one FEBRUARY 2025
