In this episode of Build & Thrive, host Jennie Armstrong is joined by Andy Mitchell, CEO of Tideway, and Steve Hails, Director of Business Services and Health, Safety & Wellbeing, to explore how one of the UK’s most ambitious engineering projects became a benchmark for culture, care, and collaboration in construction.
Together, they discuss how the £4.6 billion Thames Tideway Tunnel - or “Super Sewer” - didn’t just clean up London’s river, but redefined what it means to build with purpose. From designing health and wellbeing into every contract, to creating the now-famous “RightWay” culture and industry-first Epic Induction, Tideway proved that profitability and people-first values can thrive side by side.
Jennie reflects on her own seven-year journey with the project, as Andy and Steve share the honest lessons, challenges, and decisions that shaped one of the most progressive safety and wellbeing programmes in the sector - including how genuine care from leadership created trust, loyalty, and lasting change across thousands of workers and suppliers.
What we cover:
- How Tideway combined world-class engineering with a culture of care
- The vision that set new benchmarks for health, safety & wellbeing
- Building “one team” across client and contractors through trust and respect
- The role of leadership in designing a healthy culture from the start
- Why caring isn’t a cost - and how client-led change transforms outcomes
- Lessons on fatigue, mental health, and the legacy of transformational leadership
Andy and Steve show that when a project starts right - with purpose, people, and partnership at its core - it becomes more than infrastructure. It becomes a legacy.
If you want to understand how culture, health, and leadership can transform construction projects - this episode is essential listening.
