A world record attempt is being made at North America’s largest construction trade show, CONEXPO-CON/AGG, held at the Las Vegas Convention Center. The GUINNESS WORLD RECORDS attempt will be for the ‘most people wearing high-visibility vests’. This is scheduled for March 3, 2026 and aims to shatter the existing record of 2,499 participants and shine a spotlight on how the construction industry helps boost infrastructure worldwide.
“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.”
Participants in the record-breaking attempt will receive commemorative safety vests and be recognised 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 GUINNESS WORLD RECORDS.
