Big 5 Construct Saudi opens on Sunday 30 August at the Riyadh Front Exhibition & Conference Center and runs to Wednesday 2 September. This is what the exhibition covers, who is speaking, how the co-located shows are organised, and how to plan a visit that is worth the four days.
Big 5 Construct Saudi opens tomorrow at the Riyadh Front Exhibition & Conference Center and runs for four days, from Sunday 30 August to Wednesday 2 September, under the patronage of the Ministry of Industry and Mineral Resources. This is the practical guide to it.
The venue is at ROSHN Front, beside King Khalid International Airport in Riyadh, which makes it one of the more straightforward exhibition centres in the Gulf to reach from an inbound flight and one of the less convenient from central Riyadh at rush hour. Anyone flying in for a single day should plan around that in one direction only.
The exhibition covers the early and heavy end of construction rather than the finished product. Its four sector pillars are general construction, concrete, heavy equipment and HVACR, with facilities management alongside them, and each is separated into a co-located show: Heavy Saudi Arabia for equipment and machinery, Totally Concrete Saudi Arabia, HVACR Saudi Arabia, and Saudi FM & Clean for facilities management and cleaning. The theme this year is From foundation to future, built for every scale.
The organiser expects more than 1,000 exhibitors from over 50 countries and more than 35,000 trade visitors across the four days. The visitor number is a planning expectation rather than a recorded figure, and should be read as such until the show reports its own attendance.
The exhibitor mix runs from long-established international suppliers to first-time entrants. Among the new names this year are Arkaz, the Al Khobar construction chemicals producer owned by the Alturki group, TotalEnergies, Hamte Group in construction technologies and engineering solutions, and Mectco in waste management and environmental products. International first-timers include Australia's Lanmix, showing steel fibre reinforcement, and Egypt's K-Flex Insulation, presenting thermal, acoustic and fire-stopping systems. The full exhibitor directory is published online and is the single most useful thing to review before travelling, because a floor of that size is not walkable without a shortlist.
The conference programme runs alongside the exhibition across nine topic areas: codes, standards and regulations; health and safety; sustainability; artificial intelligence; technology; project management; concrete; modular construction; and HVACR. Individual sessions address navigating the Saudi Building Code, improving concrete quality, strengthening project governance, applying artificial intelligence in project delivery, and coordination between HVACR design, installation and facilities management.
Speaking organisations include the Saudi Building Code Center, ROSHN Group, SEVEN, Misk City, Saudi Binladin Group, Kabbani Construction Group, Al Kholi Group, Modern Building Leaders and Dussman Ajlan & Bros. Among the named speakers are Christopher Seymour, managing director for the Middle East and Africa at Mace Consult, and Shonagh Kinnaird MCIOB, project director at Misk City, whose sessions examine collaboration between stakeholders, digital transparency, procurement challenges and lessons from the Kingdom's major developments.
The Big 5 Impact Trail is the sustainability route through the floor, spotlighting solutions that improve efficiency, reduce environmental impact and support long-term building performance. Solutions on the trail this year come from Masdar, with Kronospan wood-based panels and engineered boards; Galaxy Technology, showing Albion Valves with carbon transparency across its cast iron range; Star Factory, in spray polyurethane foam roofing and waterproofing; Keller, in ground improvement and foundations; and Al-Futtaim Engineering, in integrated facilities management. It is a useful route for anyone whose brief includes embodied carbon, because it collects the products that have published numbers.
Registration and the visitor guide are available through the event website, and the organiser publishes event information including venue details separately. The show also runs active accounts on X and Facebook, which in practice are where programme changes appear first.
On planning the visit itself, three things are worth deciding in advance. The first is which of the four co-located shows a visitor is actually attending, because equipment, concrete, cooling and facilities management are separate buying conversations with separate exhibitors, and treating the event as one exhibition is how people lose a day. The second is whether the conference or the floor is the priority: the programme is heavily weighted toward the first two days and the tracks run in parallel, so a technical team covering more than one discipline has to split. The third is who the visitor needs to meet rather than what they need to see. In a market where the average project award has roughly doubled in size and clients audit local content, the value of an exhibition is in prequalification conversations, and those work better booked than wandered into.
The context the event opens into is a contracting market letting fewer and much larger packages. The Saudi Contractors Authority recorded 25 awards worth more than SR29.5bn in June, the busiest month of 2026 by count, and expects the value of projects in the Saudi market to exceed SR3 trillion over the next three years. The exhibition is where a large part of the supply chain for that pipeline will be in one building for four days.
