As a Tourism Professor with extensive travel experience—having spent 134 days abroad this year alone—I've observed that airports still have significant potential for improvement in delivering a seamless and enriching experience not just for travelers but the people who see them off, the people who receive them; and those who work in airports. People travel for leisure, relaxation, and well-being, yet airports are often the anti-thesis of these experiences. They are typically formal, cold, stressful, and costly environments. Drawing on my expertise, I'd like propose the following enhancements that could transform airports into truly modern hubs of convenience and comfort: 1. Enhanced Workstations and Charging Points: Despite the advancements in travel technology, many airports in 2024 still lack sufficient workstations and charging points for mobile devices. Ensuring that travelers can stay connected and productive is essential for a modern travel experience. 2. Streamlined Security and Check-In with Biometrics: The use of biometric identification can significantly reduce wait times at security and check-in, offering a more efficient and stress-free process for passengers. 3. In-Gate Food and Purchase Delivery: Viewing airports as mini-cities opens up innovative possibilities, such as integrating food delivery apps to allow passengers to have meals and other purchases delivered directly to their departure gate. This would not only enhance convenience but also support local F&B outlets. 4. Utilization of Outdoor Spaces: Airports can transform outdoor or rooftop areas into nature immersion zones, offering amenities like yoga sessions, outdoor cinemas, and picnic spaces to detract from the stress of terminal life. 5. Sleep Pods and Quiet Spaces: The provision of sleep pods and quiet areas would offer much-needed respite for passengers during long layovers or delays. 6. Work-Friendly F&B Outlets: By integrating workspaces and charging ports within food and beverage outlets, airports can cater to business travelers who require functional spaces to stay productive while on the move. 7. On-Site Fitness and Wellness Facilities: With the increasing emphasis on fitness and well-being, airports should consider offering gyms and fitness spaces, allowing passengers to maintain their wellness routines even while traveling. 8. Dedicated Meditation Rooms: Incorporating meditation rooms would provide travelers with a peaceful retreat, promoting mental well-being and stress relief during their journey. These suggestions expand airport markets to serve not only travelers but also the workers and the loved ones who see them off and welcome them upon arrival. They also only align with current travel trends and position airports as pioneers in enhancing the overall experience. I am available for consultation and research to explore how airports can become an attractive tourism space. #airports #thetourismprofessor

New Austrian Tunneling Method, is a highly adaptable and observational approach to tunnel construction that focuses on utilizing the inherent strength of surrounding rock or soil to provide primary support. Unlike conventional tunneling methods that rely heavily on pre-installed support structures, NATM emphasizes real-time monitoring and continuous adjustments as excavation progresses. This method is particularly effective in varying geological conditions, as it allows engineers to optimize tunnel stability by adapting support measures based on ground behavior rather than following a rigid, predefined #design. The key principle of NATM is to mobilize the self-supporting capacity of the ground through controlled deformation, using techniques such as sprayed concrete (shotcrete), rock bolts, lattice girders, steel arches, and grouted anchors to reinforce the tunnel lining only where necessary. Engineers rely on instrumentation and geotechnical monitoring to assess deformation, stress redistribution, and rock mass response, making real-time adjustments to excavation sequences and support applications. This adaptive approach not only improves safety but also minimizes material usage, making it a cost-effective solution for tunnel projects in complex and uncertain geological conditions. NATM has been widely applied in highway, railway, and metro tunnels, particularly in mountainous terrain where geological variability is a major challenge. The method also allows for the construction of large-span tunnels with irregular cross-sections, making it highly versatile for modern infrastructure projects. By integrating advanced monitoring technologies and geotechnical expertise, NATM ensures that tunnel construction remains efficient, safe, and environmentally sustainable.

🔧 Slab Strengthening Using Thickening (Top-Up & Drop Panels) In structural retrofitting, slab thickening—whether by top-up slabs or drop panels—is a highly effective method to enhance load capacity. I’ve led multiple projects where this technique played a key role in restoring and upgrading structural performance. ✅ Critical success factors in implementation: 📐 Design compliance: Ensure the additional concrete layer is engineered for the required structural behavior—especially in shear and flexure. 🧱 Drilling & Anchoring: Follow exact drilling depths and spacing per design, and use the correct epoxy or mechanical anchors to ensure a reliable connection between the old and new slab. 🧽 Surface Preparation: The substrate must be roughened, cleaned of dust and laitance, and properly primed with bonding agents to guarantee monolithic behavior. 🚧 Casting & Pumping Techniques: Form-and-Pour: Ideal when you have clear access to the casting area. After setting up formwork under the slab, concrete is poured by gravity from above. This is straightforward but requires enough workspace and headroom. Form-and-Pump: Used when access is limited or when pouring from the top isn’t possible. Concrete is pumped into the formwork under pressure—especially suitable for drop panels or soffit strengthening. Requires skilled coordination to avoid segregation or voids. 🛠️ As a Project Manager, I’ve successfully delivered a wide range of strengthening projects using both techniques. The difference always comes down to detailed planning, execution discipline, and clear understanding of site constraints. #SlabStrengthening #ConcreteRepair #StructuralRehabilitation #FormAndPump #FormAndPour #ProjectManagement #EngineeringExecution #RetrofitSolutions

Every 38 Seconds — The UAE Takes Off Between January and May 2025, UAE airports recorded an estimated 336,719 flight movements that���s one flight every 38 seconds, marking an 8.08 % year-on-year increase. Numbers like these don’t happen by coincidence. They are the product of a 20-year national strategy that turned geography → logistics → diplomacy → economic power. The Architecture of Acceleration 1. Policy as Infrastructure The UAE’s aviation rise is built on sovereign foresight, not market luck. • Civil Aviation Strategy 2030: targets AED 420 B contribution to GDP. • 150 + Open Skies agreements link 300 + cities / 100 + countries. • Unified coordination between GCAA + national carriers ensures coherence over competition. 2. Infrastructure Ahead of Demand The UAE builds before demand arrives: • DXB: 92.3 M passengers (2024) → 120 M by 2030. • DWC: AED 128 B redevelopment → 260 M passengers / 12 M tonnes cargo. • AUH: 45 M capacity (+28 % YoY). • Total: ~147.8 M passengers (+11 % vs 2023). The result: a logistics super-grid engineered for speed, scale and sovereignty. 3. Geo-Economic Advantage • Within 8 hours → 70 % of population / 85 % of global GDP. • ⅔ of global cargo moves through Asia–ME–Europe corridor anchored by UAE. • DAOP: +57 % airspace capacity, –15 % emissions. 4. Technology Edge • AI-based ATC: 1,000 + daily flights optimized. • Biometric borders: < 3 sec processing. • Predictive maintenance: –25 % downtime. • SAF partnerships: 1 B litres by 2030 → Net Zero 2050. • UAM + Space-Air Integration under GCAA & UAE Space Agency. Aviation in the UAE isn’t just flying — it’s becoming digital infrastructure. The Economic Multiplier Aviation is the circulatory system of the UAE economy: • Contributes ≈ 18 % of GDP (≈ AED 240 billion / US $92 billion). • Supports ~ 1 million jobs directly and indirectly. • Generates AED 30 + billion in tourism spending annually. • Drives AED 270 + billion in re-export trade value. • Every +1 million passengers = ≈ AED 4.5 billion added to output (estimate). Connectivity isn’t convenience — it’s competitiveness in motion. Momentum as a National Habit While others chase recovery, the UAE compounds acceleration: • +8.08 % aviation growth (2025 YTD) • +5 % GDP growth forecast (2025) • +30 % YoY FDI inflows (2024) • 91 M + passengers at DXB / 45 M capacity at AUH / 260 M planned at DWC Growth here isn’t a phase — it’s a system. The Bigger Picture The UAE doesn’t just build airports. It builds influence infrastructure — where runways connect continents, and airspace connects ambitions. Every 38 seconds, a plane takes off. But what truly takes off is the story of a nation that mastered the science of momentum. This is not aviation growth — it’s economic choreography. Every runway, every agreement, every second in the air reflects one truth: The UAE doesn’t just compete globally — it sets the flight path for others to follow.

Airport terminal projects don’t go over budget because of “bad architects” – they go over budget because the requirements programme was never aligned with strategy in the first place. In almost every terminal planning project I’ve been involved in, there is this moment halfway through concept design when the management suddenly realises the project does not fit the budget. But the architect says: “𝘞𝘦 𝘴𝘦𝘦 𝘩𝘢𝘳𝘥𝘭𝘺 𝘢𝘯𝘺 𝘳𝘰𝘰𝘮 𝘵𝘰 𝘳𝘦𝘥𝘶𝘤𝘦 𝘤𝘰𝘴𝘵𝘴 – 𝘵𝘩𝘦 𝘮𝘢𝘪𝘯 𝘥𝘳𝘪𝘷𝘦𝘳 𝘪𝘴 𝘣𝘶𝘪𝘭𝘥𝘪𝘯𝘨 𝘢𝘳𝘦𝘢, 𝘢𝘯𝘥 𝘵𝘩𝘢𝘵 𝘤𝘰𝘮𝘦𝘴 𝘥𝘪𝘳𝘦𝘤𝘵𝘭𝘺 𝘧𝘳𝘰𝘮 𝘺𝘰𝘶𝘳 𝘳𝘦𝘲𝘶𝘪𝘳𝘦𝘮𝘦𝘯𝘵𝘴.” By that time, the project has often already been running for 1-2 years, especially after starting with a design competition. Several person-years of work are already invested. And only 𝘵𝘩𝘦𝘯 does the organisation really start to question its own requirements. How did we get here? In many airports, the space programme is created before planners come on board. A typical logic is: • forecast peak-hour demand for a process (check-in, security, etc.) • assume a throughput per unit (e.g. passengers per security lane and hour) • multiply by a “standard” area per unit Often, the IATA ADRM is used as an argument: “These areas are predefined anyway.” In practice, that is rarely true. In 20 years, I have never seen two identical calculations based on that document. What I 𝘥𝘰 see again and again: 1. requirements based mostly on the past, not on the airport you want to be in 10–20 years 2. well-meant “hidden reserves” that are not transparently discussed 3. limited understanding of actual process times and possibilities for improvement There is a better way! Projects that work smoother start with a strategic discussion 𝘣𝘦𝘧𝘰𝘳𝘦 the space programme: • What should fundamentally work differently in the new terminal? • Which processes must run more efficiently? • What concrete targets do we set (e.g. capacity per security lane)?    From this, you can derive clear strategic guidelines. And instead of fixing every number upfront, some topics are turned into design questions for the competition or early concept design (for example: “How much space would we get for gate holdrooms under different design concepts?”). Client and planners then explore options together and decide based on real layouts and data, not just abstract assumptions. The result: leaner, more effective terminals - and far fewer painful, expensive redesigns halfway through the project. Curious how do you approach requirements programmes – do you start with strategic questions, or with fixed square metres? you will find a longer version of this article on my blog.

There was enough power, but there wasn’t enough resilience. Last week’s Heathrow shutdown wasn’t just a power outage—it was an exposure. A transformer fire at the North Hyde substation took out electricity to the world’s second-busiest airport. The ripple effects were felt across global aviation, supply chains, and headlines. John Pettigrew, CEO of National Grid, says the other two substations serving Heathrow had enough capacity to keep the airport running. So why the closure? Because operational resilience isn’t just about capacity—it’s about design, systems, decision-making, and time. Heathrow’s CEO explained that they had to shut down thousands of systems and methodically reboot them to ensure safety. Backup generators existed—but only to cover critical safety systems, not full operations. Switching to alternate substations wasn’t instantaneous; reconfiguring and restoring took hours. This is a classic example of design resilience vs. lived resilience. We often assume that having backup available is enough. But in complex systems—airports, hospitals, data centers—it’s how quickly and safely that backup can be activated that defines true resilience. Other major airports have made resilience a priority: - JFK, New York – 110 MW gas-fired CHP plant enabling full microgrid operation during outages. - Frankfurt Airport – Redundant grid feeds, on-site gas turbine generation, and UPS systems. - Amsterdam Schiphol – Integrated energy management system with diesel and battery backup for essential systems. - Changi Airport, Singapore – Multiple grid connections, standby diesel generation, and automated switchgear. - Incheon International, South Korea – Dual-feed substations, backup diesel generators, and smart grid control. These airports understand that resilience isn’t a luxury—it’s a license to operate. This is the future of energy for critical infrastructure: - Decentralized - Redundant - Fast-switching - Integrated with grid and on-site systems. If Heathrow—despite being served by three substations—could still go dark for nearly 24 hours, the question isn’t who to blame. It’s what to build differently. Are we designing our infrastructure for availability, or for agility? Are we investing in energy systems that can recover, or just survive? Let’s make sure this isn’t just a red flag—it’s a redirection. #EnergyResilience #InfrastructureLeadership #FutureOfPower #CriticalInfrastructure #Heathrow #GridSecurity #Digitalisation #Electrification

I've been giving morning lectures on sustainable development to a group of visiting undergraduates this week. One of the topics is how land constraints pose a sustainability challenge for Singapore and we deal with it by institutionalizing a systematic and recursive land use masterplanning process. The Urban Redevelopment Authority (URA) is the government agency that leads the national Master Plan, which guides Singapore's development over a rolling period of 10 to 15 years. The plan is reviewed every 5 years and cascades down to detailed precinct-level plans. The planning process is dynamic, such as using land set aside for industrial use to accommodate the Punggol Digital District. All the land use information is available online at https://lnkd.in/gS95eFi8 for individuals and businesses to view and download. There's even an island-wide physical model at URA's City Gallery (which I encouraged the students to visit). Just this week, the government announced the formation of the Economic Strategy Review (ESR) Committees to chart new directions for the economy amidst geopolitical issues and risks. In 2001-2002, I was an EDB officer who staffed the Education Workgroup of the Economic Review Committee chaired by then DPM Lee Hsien Loong. From then until now, there were other Ministerial Committees  such as the Economic Strategies Committee in 2010, the Committee on the Future Economy in 2016-2017 and Emerging Stronger Taskforce in 2020-2021. An observation about these ad hoc committees is that the linkage with past committees’ work is not apparent. There’s also limited down-the-road public assessment of whether the recommendations have been implemented. I’m wondering whether economic planning for Singapore can be modelled after the land use masterplanning, e.g. have a rolling 10-20 year economic plan that cascades down to specific regional/sectoral plans with real-time and publicly accessible monitoring of key metrics as well as ongoing policy finetuning and implementation. Perhaps the new ESR can look at not only what to plan but also how to plan better. #sustainabledevelopment #masterplan

India’s V2V Moment. How Cars Talking to Each Other Could Save 90,000 Lives a Year by 2030 On January 8, 2026, Nitin Gadkari announced something far more radical: Mandatory Vehicle-to-Vehicle (V2V) communication in all new vehicles. If executed well, this could become India’s single most powerful road safety intervention ever. ✅ Why This Matters: India’s Road Crisis in One Snapshot India has a public health emergency. 5 lakh accidents every year. 1.8 lakh deaths annually, one death every 3 minutes. 66% victims aged 18–34, the demographic dividend. ₹3+ lakh crore annual economic loss (3% of GDP). The government’s target is clear: 1. Cut fatalities by 50% by 2030. 2. That’s 90,000 lives saved every year. 3. 500 lives every single day. ✅ What Was Announced 1. This isn’t a pilot. It’s a mandate. 30 MHz spectrum (5.875–5.905 GHz) earmarked exclusively for V2V. Spectrum provided free, no auction, no delay. Joint task force between the Road Transport Ministry & DoT. Notification by end of 2026. 2. Every vehicle broadcasts basic safety data 10 times/sec: Location, speed, direction, braking status & vehicle type. Cars around you hear this and warn you before you can see danger. 3. Traditional road safety depends on perfect roads, perfect enforcement, and perfect human behaviour. India has none of the three. V2V works despite chaos. That’s the breakthrough. ✅ The Economics: Why This Pays for Itself Per-vehicle cost: ₹5,500–16,000 (1–4% price impact on most cars) Industry-wide investment (2027–2030): ₹20,000–60,000 crore annually What India gets in return: - ₹1.5 lakh crore annual savings from accident reduction - 10–20% lower insurance premiums for owners - 2.5 lakh fewer trauma hospitalisations - ₹4.5–9 lakh crore productivity preserved by saving young lives - ROI: 1–2 years at the national scale. ✅ Who Wins, Who Struggles Winners - Large OEMs: Maruti, Hyundai, Tata, Mahindra. - Auto electronics suppliers: Bosch, Continental, Denso. - Fleet operators (trucks, buses, ride-hailing). ✅ The Two-Wheeler Problem India Can’t Ignore 1. 24 cr two-wheelers 2. 35–40% of all road deaths 3. ₹15,000 tech on an ₹80,000 bike = 19% price jump 4. Cars & commercial vehicles first, premium two-wheelers next, subsidised rollout for delivery & fleet bikes, and full penetration only by the mid-2030s. Without solving two-wheelers, a 50% reduction stays out of reach. 5. V2V alone: 20–30% reduction; V2V + enforcement + safer roads + behaviour change: 40–50% is achievable. This isn’t magic. It’s systems engineering. Instead of fixing human behaviour first, it’s engineering around human failure. If India executes this right, it won’t just reduce accidents. It will prove that technology can save lives at population scale. The cars will start talking soon. For 90,000 Indians every year, that conversation could mean the difference between life & death. #automotiveindustry #india #tech #infrastructure #engineering

Helsinki just marked a full year without a single traffic fatality. https://lnkd.in/ec--U4Ar I once cycled through Finland (interspersed with train travel to make it round some of their 187,000 lakes!) From this I became slightly obsessed with travel pattens and transport options across the country. So, coming across this latest headline was great to see, but it wasn’t a surprise as such, it’s been years in the making. And here’s why:   It’s not just about safer crossings or speed limits in isolation. Helsinki’s transport authority uses tools like mobile sensing (e.g. TravelSense) more recently real-time bike-share data, and detailed travel-time matrices to understand the spatial and temporal rhythms of the city. 📍 They know which streets see early-morning cycle spikes. 🚶♀️ They can track when pedestrian volumes rise near rail hubs. 🚌 They model access to schools, services, and jobs by time of day and by mode Data‑driven infrastructure and policy in Helsinki isn’t blind, it's tuned to when and where people move, across different user types and modes. This long term data gathering and understanding is a key driver behind the city’s safety and modal‐shift successes. This insight supports practical decisions—30 km/h limits around schools and residential zones, widened footways and separated bike lanes in high‑footfall areas, and targeted improvements in under-served parts of the city. All this feeds into how people behave and how we use this to shift behaviour. As the article points out, the credit for zero deaths belongs not just to infrastructure, but to everyone using the road. When public space invites care, predictability and mutual respect, behaviour changes too. Better safety isn’t just about enforcement or campaigns. It’s about designing systems that anticipate movement patterns, support good decisions, and allow human error without tragic consequences. 👉 In other words: this is a Safe System approach in practice.
