CONEXPO-CON/AGG, one of North America’s largest construction tradeshows, will attempt to make history at its triennial show. Held at the Las Vegas Convention Center, GUINNESS WORLD RECORDS will be in attendance to attempt the most people wearing high-visibility vests. The attempt, scheduled on March 3, 2026, aims to break the existing record of 2,499 participants while casting a spotlight on the vital role the industry plays in shaping communities and infrastructure across the globe.
Attempting a world record at CONEXPO-CON/AGG
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 $2.2 trillion impact of the U.S. construction sector — whose companies and workers influence transportation, resource mining, sports venues, civic and cultural monuments, and countless other facets of daily life.
CONEXPO-CON/AGG, held every three years, is March 3-7, 2026, and attracts nearly 140,000 attendees and over 2,000 exhibitors from around the globe centred around the latest technology, innovations, and solutions from the biggest companies in construction. Its 2026 speakers on groundbreaking industry topics include Caterpillar, John Deere, AWS, Autodesk, and more.
“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 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 GUINNESS WORLD RECORDS.
