We're looking at five remarkable super structures: the Statue of Unity in India, the Danyang-Kunshan Grand Bridge and the Great Wall of China, the Emily Moor Transmitting Tower, the Icon of the Seas cruise ship, and the Burj Khalifa in Dubai, emphasising the engineering marvels behind these giants!

Becky and Lloydie delve into the challenges and innovations involved in constructing the Burj Khalifa, such as its design inspired by the Hymenocallis flower, its wind resistance, and its sustainable features like solar panels and irrigation systems that utilise air conditioning condensation.

The episode also features an interview with a senior structural engineer, who shares insights into her career and highlights some of the most interesting projects she has worked on, including a floating swimming pool and a 33-story building!
