Engineering Talent Takes Centre Stage at the Bechtel ENKA Innovation Expo
A waste rubber glove and a slope sensor aren’t the sort of things you’d expect to headline an awards ceremony. Yet those two ideas walked off with the top honours at the first Bechtel–ENKA Innovation Expo, held this year in Belgrade, where nine student teams from Serbia and North Macedonia put working proof-of-concepts in front of a panel drawn from the joint venture and UK Export Finance. The brief was deceptively simple: take a real engineering headache from a live megaproject and show how a fresh pair of eyes might fix it.
What made the event worth watching wasn’t the polish of the pitches, although there was plenty of that. It was the fact that these weren’t classroom exercises dreamt up in the abstract. Over the preceding four months, the students worked alongside engineers from across the joint venture’s infrastructure business, with mentors steering them from a rough idea towards something a project director could actually use on a flood-prone motorway corridor.
For a region rebuilding its road network at pace, that link between the lecture hall and the laydown yard is the part that carries real weight.
Briefing
- Two student teams shared the top prize at the inaugural Bechtel-ENKA Innovation Expo in Belgrade, one for an early-warning slope deformation alarm and one for recycling waste rubber gloves into asphalt.
- Nine teams from Serbia and North Macedonia competed after four months of mentoring by joint-venture engineers, with judges including UK Export Finance representatives.
- The winning ideas tackle two of the costliest risks on Balkan road projects: landslides driven by heavier rainfall, and the durability and waste burden of asphalt.
- The Expo sits alongside the Bechtel-ENKA team’s work on the 112km Morava Corridor, Serbia’s largest single infrastructure programme.
- Winners now get access to project sites and laboratories to develop their concepts with working engineers.
Two Ideas That Caught The Judges’ Eyes
The Serbian winners, working under the banner Geotechnical Stability & Slope Protection, built an early slope deformation alarm offering round-the-clock monitoring of unstable ground. The thinking behind it is grounded in a problem every highways engineer in the region knows well. Slopes that look stable in dry weather can shift suddenly after prolonged rain, and by the time a crack is visible the damage is often done. The team’s system, developed by Jasmina Batrnjin, Zorka Lazarević and Matija Milhavjlovic, is designed to flag movement early enough for crews to step in before a minor slip becomes a closed carriageway or a buried machine.
The North Macedonian winners came at sustainability from a different angle. Their team, Pavement Durability & Lifecycle Optimization, looked at the black nitrile gloves that get binned by the thousand on any construction site and asked whether the rubber could earn a second life. Ana Petrova, Leontina Ilievska and Viktorija Velinska worked up a method for recycling those gloves into asphalt mixtures, with the aim of improving the physical and mechanical properties of the blend while cutting waste at the same time. Both teams now get to take their concepts into Bechtel-ENKA’s sites and labs, which is where a promising idea either proves itself or quietly falls over.
Why Slope Monitoring Earns Its Keep In A Wetter Balkans
There’s a reason a slope alarm resonated with this particular panel. The Morava Corridor cuts across a flood plain of the West Morava River, and managing water has been one of the defining challenges of the build from the outset. The joint venture has already constructed what’s been described as the first flood mitigation system of its scale built alongside a motorway in the Balkans, a response to the Serbian government’s push to harden its infrastructure against extreme weather. A student tool that spots ground movement before it turns into a landslide fits neatly into that wider resilience picture.
The economics stack up too. Landslides and slope failures don’t just threaten safety, they generate lost days, emergency repairs and the kind of unplanned downtime that wrecks a construction programme. Continuous monitoring shifts the work from reactive to preventive, letting teams intervene while the fix is still cheap. With climate models pointing to heavier and more frequent rainfall across south-east Europe in the decades ahead, the case for cheap, always-on slope sensors only gets stronger. It’s a small piece of kit aimed at a very expensive problem.
Turning Waste Gloves Into Tougher Tarmac
The asphalt idea taps into a field that’s been quietly maturing for years. Researchers have long shown that crumb rubber recovered from end-of-life tyres can improve asphalt performance, boosting resistance to rutting and fatigue cracking while adding stiffness and durability. The elastic nature of rubber tends to make road surfaces less prone to the cracks and potholes that open up under cold, wet conditions, which is precisely the climate much of the Balkans contends with each winter. What the North Macedonian team brought was a twist on a familiar theme, swapping waste tyres for waste gloves and pointing the same circular-economy logic at a different stream of site rubbish.
That distinction matters more than it might first appear. Construction sites generate enormous quantities of single-use protective gear, and most of it heads straight to landfill. Diverting even a fraction of that into the road itself would tackle two problems with one mix: less waste leaving the gate, and a potentially harder-wearing surface staying behind. The concept still needs laboratory validation before anyone paves a live carriageway with it, and the students will be the first to test the mechanical claims under controlled conditions. Still, the principle is sound and the timing is right, with road authorities everywhere under pressure to cut both maintenance bills and embodied carbon.
The Wider Field Of Proof Of Concepts
Beyond the two winners, the rest of the field showed the same instinct for solving practical headaches. One team built an AI communication platform that turns spoken field notes into clear, structured data, trimming the administrative write-ups that eat into an engineer’s day. Another proposed cutting the cost of retaining walls by swapping conventional backfill for recycled tyres, a neat companion to the glove idea and another nod to keeping waste out of landfill. A third developed a cross-device app that tracks inventory, orders and live vendor pricing in one place, giving site managers a clearer line of sight on missing stock and quicker deliveries.
Perhaps the most ambitious entry fused several technologies at once. The team combined ground-penetrating radar, vehicle-mounted LiDAR scanners and satellite analysis into a single platform for spotting cracks, potholes and other damage across a construction site, so repairs can be actioned before small defects spread. Pulling those data sources together is no trivial task, and the fact that students were even attempting it says something about how quickly survey and sensing technology has filtered down into mainstream civil engineering. None of these will go straight to market, but each one points at a genuine gap worth closing.
Technology Already Out On The Ground
The Expo wasn’t only about ideas in waiting. It doubled as a showcase for tools the joint venture is already rolling out on its projects, giving students a look at where their concepts might eventually sit. On display were Propeller’s drone-based mapping software, dust monitoring programmes, low-carbon concrete and a handful of other innovations being put to work on live sites. For young engineers, seeing the gap between a prototype and a production-ready system is a lesson no lecture quite delivers.
That blend of aspiration and application is the point. By putting students next to working kit, the organisers gave them a realistic sense of the standards their own work will have to meet. Hosting the event at the University of Belgrade’s Faculty of Civil Engineering, in collaboration with North Macedonia’s University St Cyril and Methodius, kept it rooted in the academic institutions feeding the next generation of talent into the regional industry. It’s the sort of partnership that pays off slowly, then all at once.
A Talent Pipeline With Three Decades Behind It
The judging panel carried real seniority, which gave the students a tough but fair audience. It featured UK Export Finance’s Country Head for the Balkans and Central Eastern Europe, Dusko Krsmanović, alongside Bechtel’s Infrastructure General Manager for the Balkans Heavy Civil arm, Josh Baker, the firm’s AI programme manager for infrastructure, Stephen Smith, and from ENKA, Vice President for Design and Engineering Yalçın Karabulut and Morava Corridor Project Engineering Manager Erdoğan Kılıç. Reflecting on the event, Baker said: “The true highlight was witnessing the students’ ingenuity as they applied creativity and discipline to solve real engineering problems. Their confidence and dedication were truly inspiring.”
Smith framed the value in terms of careers as much as projects, noting: “These students have had an excellent chance to put their classroom knowledge into practice by addressing major challenges that occur in megaprojects. The Expo was a great experience for both our teams and the students to exchange ideas and strategies for problems they will face in their careers.”
Launched in January 2026, the Expo joins a broader run of stewardship work in the region, from backing the FIRST Lego League to refurbishing and sponsoring university engineering faculties. It all sits on top of a three-decade legacy that has seen Bechtel involved in nearly 750km of motorway across the Balkans, with the 112km Morava Corridor, running east to west from Pojate to Preljina and linking Serbia’s north-south motorway between the Hungarian and North Macedonian borders, the headline act. On that kind of stage, giving students a real say in how the next generation of roads gets built looks less like outreach and more like succession planning.
