Runways are essential infrastructure at any airport, as they enable aircraft to take off and land safely and efficiently. Together with airfields, these areas ensure the smooth flow of air operations and the airport’s ability to handle high traffic volumes.

At Sando Infraestructuras y Proyectos, we combine experience, technological innovation, and sustainability to design and build runways and airfields tailored to each client’s specific needs.

What is a runway?

A runway is a surface specifically designed to allow aircraft to take off and land safely. Runways at major airports are paved, while those at smaller airfields may be made of dirt or grass. Their dimensions, materials, and orientation depend on factors such as the type of aircraft that will operate there, expected air traffic, and local weather conditions.

Key components of runways

1. Dimensions and operational capacity
   The size of the runways determines the types of aircraft that can use the airport. For example:
   • Standard length: Large aircraft require runways of at least 2.5 km to take off and land, although at international airports such as Adolfo Suárez Madrid-Barajas, runways can be longer than 3 km.
   • Standard width: Most runways have a minimum width of 60 meters, which is sufficient for safe maneuvers.
2. Have you ever wondered how long a runway is?Dimensions may vary depending on the airport’s design and purpose, but these figures are typical at major airports around the world.
3. Orientation based on wind patterns
   Runways are oriented to minimize the crosswind component, ensuring safe operations. In addition, runway thresholds and approach areas must be free of obstacles to prevent hazards during maneuvers.
4. Clear spaces and safety zones (RESA)
   Safety areas at the ends of the runway are essential for mitigating the impact of long or short landings, in compliance with international regulations. Clear zones are also designed around the runways to ensure operational safety.
5. Lighting and Signaling Systems
   Runways must be equipped with advanced lighting and beacon systems that enable safe operations even in low-visibility conditions or at night.
6. Specialty Flooring
   There are two main types of flooring:
   • Flexible pavements: Consisting of layers of bituminous and granular materials, which provide flexibility in response to ground settlement.
   • Rigid pavements: Constructed with concrete slabs, ideal for withstanding heavy traffic and ensuring long-term durability.

Factors to Consider in the Design of Airport Runways

The design of runways and airfields requires an analysis of multiple factors, such as:

• Frequency of flights: Increased traffic requires more durable runways and larger safety zones.
• Aircraft type: Larger aircraft require longer and wider runways.
• Weather conditions: These determine the materials used in the pavement and the design of drainage systems.
• Drainage capacity: Efficient drainage is crucial for preventing water buildup that could lead to hydroplaning.

Airfields and Their Importance

Airfields include runways, taxiways, aprons, and other operational areas that facilitate the movement of aircraft on the ground. Their design and construction aim to maximize air traffic efficiency by reducing wait times and optimizing operations. At Sando, we work to ensure that every airfield is functional and complies with the strictest international standards.

Our experience with runway and airfield projects

At Sando Infraestructuras y Proyectos, we have been involved in landmark projects that demonstrate our technical expertise and commitment to quality:

• Expansion of the second runway at Adolfo Suárez Madrid-Barajas Airport: This project improved the operational capacity of one of Europe’s busiest airports.
• Construction of the second runway at Málaga Airport: Designed to handle large-capacity aircraft, significantly improving the region’s connectivity.

Advanced technologies for runways

At Sando, we use innovative tools that improve precision and efficiency in design and construction:

• BIM (Building Information Modeling): To anticipate technical challenges and optimize resources.
• Drone monitoring: Fast and accurate inspection of runways during construction and maintenance.
• High-efficiency LED lighting: Improves visibility and reduces energy consumption.
• Water management systems: We design drainage systems that prevent dangerous water buildup on the tracks.
