One Year RIDDOR-Free at Heathrow: A Milestone in Safety and Collaboration

We’re proud to share that one of our key partners, Mace, has officially achieved a major safety milestone at Heathrow Airport: one full year without a single RIDDOR incident.

As part of the supply chain working across the airport’s ongoing projects, Design Rationale is thrilled to be part of this remarkable achievement. Over the past 12 months, more than 1.5 million man-hours have been safely completed across a day and night workforce, with activity taking place almost every weekend.

The scale of work has grown significantly, with the number of operatives more than doubling - from 400 to nearly 900 - and over 100 new Mace staff joining the effort. Despite the challenges that come with such rapid growth, this team-wide commitment to health, safety, and wellbeing has remained front and centre.

Mace will be recognising this accomplishment with a workforce stand-down event at the Renaissance to thank everyone involved for their continued dedication to safety.

We’d like to extend our thanks to Mace for their leadership and recognition, and to all the teams, including our own, whose continued focus helps ensure that everyone goes home safe and well, every day.
