A brief history of Mott MacDonald
Mott MacDonald is a global engineering, management and development consultancy with a proud heritage that stretches back more than a century. The company was founded in 1902 by Basil Mott and David Anderson as a civil engineering partnership in the United Kingdom. Their early work focused on infrastructure projects that supported industrial growth, urban development and transport expansion at a time when Britain was rapidly modernising.
The firm gained national recognition through its involvement in major railway and tunnelling projects, including work connected to the London Underground. These early successes established a reputation for technical excellence, safety and innovation. In 1989, the company merged with Sir M MacDonald and Partners, forming the modern organisation now known as Mott MacDonald. This merger brought together complementary expertise in engineering, project management and international development.
What sets Mott MacDonald apart is its employee owned business model. This structure encourages long term thinking, professional integrity and genuine collaboration. Today, Mott MacDonald operates in over 150 countries, employing tens of thousands of professionals across transport, water, energy, health, education and the built environment. The organisation is deeply committed to sustainability, digital innovation and social impact, making it a highly attractive employer for purpose driven professionals.
