When the history of landmark construction projects is written, few can rival the scale of the new IGA Istanbul Airport. Situated roughly 22 miles northwest of Istanbul on a site spanning over 18,900 acres, this mega-project is set to become the largest airport in the world upon its final phase completion in 2028. To put its size into perspective, the main terminal building alone covers 321 acres of floor space. At an estimated cost of $11.3 billion USD, the project demanded an equally monumental equipment deployment. At the heart of the logistical triumph sits a fleet of 58 tower cranes supplied by Liebherr, marking the single largest delivery of cranes for one construction site in the company’s history. The challenges of coordinating this effort between Liebherr’s Turkish and German operations, meeting strict delivery deadlines, and providing round-the-clock onsite support offer valuable lessons for construction professionals managing large-scale projects. For context on how massive infrastructure undertakings compare across history, the scale of this airport project bears similarities to the Great Wall of China Construction of the in terms of logistical complexity and workforce coordination.
Project Overview: Building the World’s Largest Airport
The IGA Istanbul Yeni Havalimani Airport, commonly referred to as Istanbul New Airport, is being developed in four phases on the European side of Istanbul near the Black Sea coast. The project broke ground in mid-2014 with initial earthworks, and by summer 2016 the site already employed approximately 13,000 workers operating 2,000 construction machines simultaneously.
Phased Construction Timeline
The phased approach allows the airport to begin operations well before full completion, a strategy that optimizes return on investment while construction continues on adjacent areas. Each phase builds on the previous one, adding capacity and infrastructure incrementally.
- Phase 1 (Completion: early 2018) — Earthworks began in mid-2014. This phase includes the main terminal, two runways, and supporting infrastructure. Upon completion, the airport will begin commercial operations while construction continues on later phases.
- Phase 2 and 3 (Completion: end of 2022) — Additional runways and a second terminal will be added, significantly expanding the airport’s capacity to handle more flights and passengers.
- Phase 4 (Completion: 2028) — The final phase brings the airport to its full design capacity with six runways, eight air traffic control towers, and the ability to handle up to 3,500 flights per day connecting to over 350 destinations worldwide.
Scale and Specifications
The table below summarizes the key technical specifications of the Istanbul New Airport project, illustrating the immense scale that construction teams had to contend with.
| Specification | Value |
|---|---|
| Total project area | 76.5 million m2 (18,900+ acres) |
| Total closed construction area | 3.5 million m2 |
| Main terminal building area | 1,300,000 m2 (321 acres) |
| Car park capacity | 18,000 vehicles |
| Terminal building concrete volume | 1,000,000 m3 |
| Ferrous reinforcement in terminal | 180,000 tons |
| Terminal roof area | 450,000 m2 |
| Daily flights (after phase 4) | 3,500 |
| Total runways (after phase 4) | 6 |
| Passenger boarding bridges | 165 |
| Annual passenger capacity | 200 million |
| Airline partners | 150+ |
The concrete volume alone for the terminal building, at 1 million cubic meters, is enough to fill over 400 Olympic swimming pools. The 180,000 tons of steel reinforcement would be sufficient to build multiple large-scale bridges or high-rise structures. It is this staggering scale that necessitated an equally impressive deployment of lifting equipment.
Liebherr’s Crane Fleet: 58 Tower Cranes for One Construction Site
Supplying and supporting 58 tower cranes on a single construction site presented unique challenges that went far beyond merely delivering equipment. Liebherr, which has been active in the Turkish market for decades, had to coordinate closely between its local sales and service company in Istanbul and its tower crane manufacturing operations in Biberach, Germany. This international collaboration proved essential to meeting the project’s demanding requirements.
Crane Fleet Composition
The crane fleet was not a random assortment of available units but a carefully calculated selection based on a detailed analysis of the site’s infrastructure, building complexes, and lifting requirements. Liebherr’s Tower Crane Solutions department conducted thorough research before recommending the optimal mix of crane models.
- 10 x 154 EC-H tower cranes — Ideal for lighter lifting tasks and areas with restricted space. These compact yet capable cranes handled material transport across the sprawling site.
- 17 x 200 EC-H tower cranes — Mid-range cranes providing a balance of reach and lifting capacity for structural steel and concrete placement in the terminal areas.
- 32 x 280 EC-H tower cranes — The workhorses of the fleet. These high-capacity cranes handled the heaviest lifts, including large prefabricated components and heavy machinery installations.
The dominance of the 280 EC-H model in the fleet reflects the heavy lifting demands of the terminal’s structural frame and roof construction. Each crane was positioned strategically to maximize coverage and minimize the need for repositioning during the construction phases.
Negotiation and Delivery Timeline
The procurement process for such a massive equipment order was compressed into an exceptionally tight schedule. Negotiations began in March 2015, and Liebherr accepted the order by mid-May 2015. The first tower cranes had to be delivered by the end of June 2015, just weeks after signing. This rapid turnaround required extraordinary coordination between manufacturing, logistics, and site preparation teams. Dominique Tasch, managing director of Liebherr-Werk Biberach GmbH, noted that the capacity of the tower cranes combined with the company’s ability to meet extremely short lead times were the main criteria that won the order. The achievement is comparable to the logistical feats seen in other megaprojects, such as when the Worlds Largest Canal Lock Opens in the Netherlands, where precision engineering and tight coordination were equally critical.
Onsite Support and Service Infrastructure
Delivering 58 cranes to the site was only half the challenge. Keeping them operational around the clock, in a demanding construction environment, required a dedicated support infrastructure that Liebherr established from day one. The company’s approach to onsite service provides a model for equipment suppliers working on mega-projects.
Permanent Onsite Presence
Liebherr stationed five fitters permanently on the construction site to ensure maximum crane availability. These technicians were responsible for routine maintenance, emergency repairs, and operational adjustments as construction progressed. Having dedicated personnel who knew the specific crane models intimately meant that downtime was minimized and issues could be resolved without waiting for external support.
Spare Parts Warehouse on Site
One of the most innovative aspects of Liebherr’s support strategy was the establishment of a dedicated spare parts warehouse on the construction site itself. Stocked specifically for the crane models in use, this warehouse was operational from the day the first tower crane was delivered. The benefits were significant:
- Eliminated waiting times for parts deliveries from external warehouses or overseas suppliers
- Reduced crane downtime to the absolute minimum for routine maintenance and unexpected repairs
- Allowed the onsite team to address multiple crane issues simultaneously without parts shortages
- Enabled just-in-time replacement of wear items, preventing small issues from escalating into major breakdowns
24-Hour Service and Remote Support
Liebherr provided round-the-clock service through a combination of local service technicians based in Turkey and technical specialists based at the Biberach manufacturing facility in Germany. This time-zone coverage meant that any issue arising during night shifts could be addressed immediately. Regular visits by technical personnel from Biberach to the Istanbul site ensured continuous knowledge transfer, training updates, and process improvements. As Danyel Temizkan, managing director of Liebherr Makine Ticaret Servis Limited Sirketi, explained, the constant flow of information between the site and the plant was critical to maintaining operational excellence. This type of multi-location support coordination is a hallmark of modern megaproject execution, not unlike the engineering coordination required for Steinway Tower Worlds Thinnest Skyscraper 2, where German and international engineering teams collaborated across borders.
Lessons for Large-Scale Construction Equipment Management
The Istanbul New Airport project offers several important lessons for construction professionals managing large-scale equipment deployments. These principles apply whether the project involves 58 cranes or a more modest fleet.
Early Technical Consultation Drives Efficiency
Liebherr’s Tower Crane Solutions department began its analysis before the contract was signed. By studying the site infrastructure, building complexes, and planned construction sequence, they could recommend the optimal crane types and positions. This upfront investment in planning reduced the need for costly repositioning and crane swaps during construction. The key takeaway is that equipment planning should begin during the design phase, not after construction starts.
Integrated Supply Chain Coordination
The coordination between Liebherr’s Turkish and German operations demonstrates the importance of integrated supply chains for international projects. With manufacturing in Germany, sales and service in Turkey, and multiple subcontractors on site, the flow of information had to be seamless. Regular communication protocols, shared technical databases, and clear escalation procedures prevented misunderstandings that could have delayed the project.
Onsite Support Infrastructure Reduces Downtime
The dedicated spare parts warehouse and permanently stationed service technicians were decisive factors in maintaining crane availability. For any large construction project, equipment downtime is a major cost driver. Investing in onsite parts inventory and dedicated maintenance personnel, while more expensive upfront, pays dividends through reduced downtime and faster issue resolution. The principles of onsite logistics and equipment coordination have deep historical roots, as demonstrated in a Guide to the Colosseum Construction of the, where Roman engineers developed sophisticated material handling systems to support the construction of the world’s largest amphitheater.
Operating in Challenging Environments
The Istanbul New Airport project continued despite political upheaval and security incidents in Turkey during the construction period. This reality highlights the importance of building resilient supply chains and support systems that can function under adverse conditions. Equipment suppliers working in volatile regions should plan for:
- Multiple sourcing options for critical spare parts to avoid single-point-of-failure risks
- Cross-trained service personnel who can cover for each other if circumstances prevent access
- Sufficient onsite inventory to weather supply chain disruptions of several weeks or more
- Communication redundancy, including satellite-based systems, when local infrastructure may be unreliable
Looking Ahead: The Completed Airport
When fully completed, the IGA Istanbul Airport will feature six working runways, eight air traffic control towers, 165 passenger boarding bridges, capacity for 500 aircraft simultaneously, and rail-connected terminals spread over 70 million square feet. It will host more than 150 airlines with a total capacity of up to 200 million passengers per year. The 58 Liebherr tower cranes that helped build this vision represent one of the most impressive equipment deployments in construction history, demonstrating what is possible when equipment manufacturers, contractors, and project owners work in close partnership from the very beginning of a project.
