98. Why Sustainability Starts Long Before Construction Begins with Hollie Hynes

In this episode of Building Doors, host Lauren Karan sits down with Hollie Hynes, a construction leader who's spent years helping shape how major infrastructure projects are delivered and how sustainability is becoming part of everyday decision-making across the industry. Having worked across environmental engineering, commercial strategy, and executive leadership, Hollie has seen firsthand what it takes to influence change in one of the world's most complex industries.

Hollie shares how following her instincts led her into construction, why some of her biggest career breakthroughs came from stepping into roles that felt uncomfortable, and how the support of sponsors helped her see opportunities she never would have pursued on her own.

Lauren and Hollie explore why sustainability shouldn't be treated as a separate conversation. Instead, they discuss how it needs to be considered from the earliest stages of planning and procurement.

The conversation also dives into leadership, imposter syndrome, building teams around a shared purpose, and balancing a demanding career with family life. They wrap up with a thoughtful conversation about legacy. For Hollie, it's about more than the infrastructure we leave behind. It's about giving people every opportunity to succeed, creating projects that genuinely benefit communities, and having the courage to rethink the way the industry works so future generations inherit something better.

Tune in for an insightful conversation about leadership, sustainability, career growth, and creating a construction industry that's built for the future.
