ConExpo-Con/Agg

will be vying for a world record when the show gets underway next month, engaging

Guiness World Records

in an attempt for the most people wearing high-visibility vests at one time.

According to ConExpo-Con/Agg, the show aims to shatter the existing record of 2,499 participants during an attempt on March 3. The show’s organizers will host the record attempt as part of ConExpo-Con/Agg’s opening ceremony by gathering thousands of attendees clad in orange construction safety vests.

ConExpo-Con/Agg aims to shine a spotlight on the role the construction industry plays in shaping communities and infrastructure across North America.

“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,” says

Dana Wuesthoff

, show director of ConExpo-Con/Agg. “We want to honor those who build our cities, roads, railways, airports, stadiums and monuments and highlight how their efforts touch every aspect of society. This record is particularly important to us as safety is, and always will be, of utmost priority for the industry and the people who make this work possible.”

The show says participants in the record-breaking attempt will receive commemorative safety vests and be recognized for their role in this historic gathering.

“We are excited to host this extraordinary moment as the construction community comes together to celebrate its innovation, sustainability advances, workforce investments and set a new world record in the heart of Las Vegas,” says Michael Empric, official adjudicator at Guiness World Records.
