The North American construction industry will attempt to set a new Guinness World Record at ConExpo-Con/Agg 2026 for the most people wearing high-visibility vests in one place. The initiative, taking place during the show’s opening ceremony in Las Vegas, is designed to

celebrate industry innovation while reinforcing safety as a core priority across construction.




Record Attempt Planned for Opening Ceremony


Organisers of ConExpo-Con/Agg 2026 are preparing a Guinness World Records attempt for the most people wearing high-visibility safety vests, set to take place during the trade show’s opening ceremony in Las Vegas, Nevada.

The attempt will be held at the Las Vegas Convention Center, bringing together thousands of attendees wearing high-visibility orange vests, with the goal of surpassing the current record of 2,499 participants.


The initiative is intended to spotlight the importance of safety culture across the construction sector while recognising the industry’s significant contribution to the US economy, estimated at US$2.2 trillion annually.

Held every three years, ConExpo-Con/Agg runs from 3 to 7 March 2026 and is expected to attract nearly 140,000 attendees and more than 2,000 exhibitors from around the world.

Industry Celebration and Safety Message


Show director Dana Wuesthoff said the record attempt represents more than just a numerical milestone.

“This record attempt is more than a number – it’s a celebration of the advances, hard work, innovation and dedication of everyone in the construction industry.”

She added that the moment is designed to honour the people and companies responsible for building critical infrastructure such as roads, bridges, airports, and stadiums, while reinforcing that safety remains a top priority across the sector.
