In this episode, Hamed Tavakoli sits down with David Worsley, founder of Worsley Consulting Engineers, to explore the evolving role of civil engineering in a climate-conscious world.
David shares his journey from early inspiration through games like SimCity to leading an innovative engineering practice, highlighting a critical shift in the profession—from focusing on “how” things are built to understanding “why” they are built. The conversation dives into how engineers can take on more strategic leadership roles, especially when involved early in project planning.
A key focus of the episode is WC3, Australia’s first purpose-built embodied carbon calculator for civil infrastructure. David explains how the tool helps designers, planners, and engineers measure and reduce carbon footprints across projects—making carbon analysis more accessible and actionable. From integration with design software to scenario testing, WC3 enables better decision-making at every stage.
One standout insight comes from a cemetery project, where up to 50% of upfront carbon emissions were linked to grave foundations—revealing how overlooked elements can significantly impact a project’s carbon profile.
The discussion also unpacks the growing importance of Scope 3 emissions (embodied carbon), especially as operational emissions decrease with grid electrification. David highlights the current gaps in legislation and why embodied carbon will soon become a central focus in infrastructure delivery.
Finally, the episode explores two key approaches shaping the future of design:
• Climate-sensitive design — integrating mitigation and adaptation using future climate projections
• Regenerative civil design — restoring natural systems through approaches like pre-settlement water management, including billabongs, leaky weirs, and contour berms
This is a conversation about leadership, systems thinking, and the tools shaping the next generation of infrastructure—where engineering moves beyond compliance to actively regenerating landscapes.
