Balfour Beatty’s name is synonymous with global infrastructure. With over 100 years of experience, the company has not only shaped the skylines and landscapes of today but has also laid the foundations for the innovations of tomorrow. From the first tramway upgrade in 1909 to pioneering projects in nuclear energy and high-speed rail, Balfour Beatty has continually redefined what’s possible in civil engineering.
This deep dive explores the company's legacy, its key milestones, and how its unwavering commitment to innovation and sustainability continues to drive industry leadership. It’s a story of overcoming challenges, seizing opportunities, and pushing the boundaries of engineering excellence on a global scale.
1909: A Modest Start with Grand Ambitions
George Balfour, an engineer, and Andrew Beatty, an accountant, joined forces in 1909 to create Balfour Beatty. Their first project, a £5,000 tramway upgrade (£745,000 in 2024 prices), set the stage for a company that would soon become synonymous with groundbreaking infrastructure.

2014: A Pivotal Turnaround: Leo Quinn and the ‘Build to Last’ Strategy

Leo Quinn, CEO of Balfour Beatty
Balfour Beatty hit a major setback in 2015, suffering a £199 million (£275 million in 2024 prices) pre-tax loss due to cost overruns and project delays. The company needed urgent restructuring, and Leo Quinn, appointed CEO that year, was tasked with leading the recovery.
Quinn introduced the Build to Last programme, a comprehensive strategy focused on cutting costs, improving risk management, and increasing transparency. The results were evident by 2016, when Balfour Beatty posted a modest profit of £8 million, signaling the start of a positive shift. By 2017, the company was on track to achieve industry-standard margins, marking a successful transition into the second phase of Quinn’s plan.
Under Quinn’s leadership, Balfour Beatty not only recovered but began positioning itself for sustainable growth, laying a solid foundation for future success.
Recent Milestones
