ConExpo organizers are attempting to add a lot more shimmer to Las Vegas.

The trade show will make a Guinness World Record attempt for the most people wearing high-visibility vests.

The attempt, scheduled for March 3, aims to shatter the existing record of 2,499 participants and shine a spotlight on the important role the industry plays in shaping communities and infrastructure across the continent.

“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,” said Dana Wuesthoff, Show Director of ConExpo-Con/Agg. “We want to honour 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.”

Trade show organizers will host the record attempt as part of ConExpo-Con/Agg’s opening ceremony by gathering thousands of attendees clad in vibrant orange construction safety vests to demonstrate the unity and collective impact of the construction sector — whose companies and workers influence transportation, resource mining, sports venues, civic and cultural monuments and countless other facets of daily life.

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,” said Michael Empric, Official Adjudicator at
