CECA 30 Under 30: Emily Mulley, HOCHTIEF (UK)

As part of CECA’s 30th anniversary celebrations, our ‘30 Under 30’ series showcases the young professionals helping to shape the future of civil engineering. Our latest profile features Emily Mulley, a Site Engineer (Surveying) at HOCHTIEF (UK).

Emily works on a 3.4km tunnel in Snowdonia, North Wales, taking complex weekly measurements to ensure the tunnel boring machine remains on its designed alignment. She is also responsible for monitoring nearby infrastructure and site assets, including railway tracks and pylons, to identify any adverse movement associated with tunnelling.

Having gained experience through the QUEST scheme during her degree, Emily has continued to take on challenging responsibilities since graduating. Her achievements include winning the South West Princess Royal Award for Emerging Engineers in 2025. She combines a thorough approach to safety and problem-solving with a commitment to supporting new colleagues and sharing her knowledge.

For Emily, one of the most rewarding aspects of civil engineering is contributing to infrastructure that benefits communities. Her work on National Grid’s cable tunnels supports the energy transition, giving her a direct role in preparing essential infrastructure for changing demands.

Looking ahead, Emily aims to continue developing her technical expertise and leadership skills. She believes that multiple small improvements can collectively make a meaningful difference to people’s lives – a principle that guides her approach to engineering.
