The largest construction event in Saudi Arabia, Big 5 Construct Saudi, returns in September 2026 to Riyadh, bringing together manufacturers, suppliers, contractors, engineers, and project leaders under one roof. Held over four days at Riyadh Front Exhibition & Conference Center (ROSHN Front), the event covers the full construction cycle — from heavy equipment and concrete to HVACR systems and facilities management. The September edition follows a rescheduling from May, aimed at enabling broader participation from across the Kingdom and international markets.

Big 5 Construct Saudi is the Kingdom's premier platform for a construction market valued at USD 1.7 trillion, driven by Vision 2030 mega-projects. The upcoming edition expects 1,300+ exhibiting companies from over 50 countries, with an estimated USD 2.13 billion in business to be generated within 12 months. Organized by dmg events, the exhibition features four co-located specialized events: Heavy Saudi Arabia, HVACR Saudi Arabia, Saudi FM & Clean Expo, and Totally Concrete Saudi Arabia.

The event targets a broad spectrum of construction professionals — contractors, developers, engineers, architects, procurement managers, and government decision-makers. The program includes Big 5 Talks, featuring panel discussions on sustainable materials, façade innovation, project management, and digital transformation, alongside the Architect Leaders Forum Saudi exploring design's role in shaping future cities. New for 2026 is the Platinum Club, offering guaranteed meetings between exhibitors and key decision-makers driving giga-projects.

The event takes place at Riyadh Front Exhibition & Conference Center on Airport Road, minutes from King Khalid International Airport. Admission is free for pre-registered industry professionals. Exhibition hours run September 19-22, 2026, daily from 4:00 PM to 10:00 PM. For registration: big5constructsaudi.com
