The 2024 Las Vegas Collision: Construction, Water & Manufacturing Technology Expo (LJCW) is a three-day, in-person trade show and conference scheduled for October 2-4 at the Las Vegas Convention Center. Built for owners, executives, project managers, estimators, superintendents, plant managers, engineers, architects, municipal water authorities and technology buyers, the event positions itself as the fastest-growing intersection of construction, water infrastructure and advanced manufacturing in North America. More than 350 exhibitors will occupy 110,000 net square feet, demonstrating drones, autonomous earth-moving equipment, 3-D-printed structures, leak-detection satellites, smart-pipe systems, AI-driven project-management software, modular robotics, carbon-negative concrete, AR safety wearables and additive-manufacturing platforms. A multi-track conference running alongside the show floor features 120 sessions divided into Construction Tech, Water Tech and Manufacturing Tech summits. Day-one keynotes include Turner Construction chief technology officer James McKelvey on “Building Zero-Overrun Hospitals,” Las Vegas Valley Water District general manager John Entsminger on “Drought-Proofing a Desert Metropolis,” and Siemens USA CEO Barbara Humpton on “Reshoring Critical Supply Chains Through Smart Factories.” Subsequent days spotlight case studies such as the NFL’s Allegiant Stadium achieving 25 % schedule compression with 4-D BIM, the Southern Nevada Water Authority’s robotic lining of 42-inch transmission mains without service interruption, and Tesla Gigafactory Nevada’s dry-electrode coating line that cut 30 % of energy demand. Certification workshops offer LEED AP, AIA LU, PDH and CWEA contact hours on topics ranging from digital twins to PFAS remediation. A Venture & Procurement Forum pairs start-ups with public agencies and Tier-1 contractors for pilot funding, while nightly receptions on the expo floor give attendees hands-on time with robotic total stations, hydro-excavation trucks and micro-factories the size of shipping containers. Registration badges grant access to all keynotes, exhibits, receptions and the mobile networking app that pre-matches participants for 15-minute meetings.
