In 2023, the global construction foundation sector witnessed a milestone breakthrough. For a long time, galvanized ground screw piles, despite being favored for their fast installation and environmental friendliness, suffered from the technical bottleneck of "inability to accurately calculate load-bearing capacity", which hindered their widespread application in large-scale buildings. However, in 2023, with the implementation of multiple innovative technologies and the issuance of authoritative certifications, this situation was completely rewritten.

Danish Team Solves a Century-Old Problem, Wins "Oscar" of Construction

In November 2023, the construction industry focused its attention on Denmark. Pilar, a spin-out company from Aalborg University, and its founding team won the prestigious 2023 Building Component Award for their disruptive software and hardware solution for screw piles.

This award, presented by the VILLUM FONDEN and VELUX Foundations, is regarded as the highest honour in the building component field. The three core recipients – Professor Lars Bo Ibsen, geotechnical engineer Jens Jacob Porsmose, and entrepreneur Niels Thorup Madsen – successfully expanded the application of screw piles from temporary sheds to permanent large-scale residential and commercial buildings through interdisciplinary collaboration.

"In the past, no one in the industry could accurately calculate how much load a screw pile could bear underground. This meant insurance companies wouldn't provide coverage, and architects dared not design with them," said Niels Thorup Madsen upon receiving the award. "Now, through sensors and algorithms, we make the soil 'speak'."

Technical Core: Giving Installation Equipment a "Smart Brain"

The core of this award-winning technology is not a change in the manufacturing process of the galvanized steel piles themselves, but a complete revolution in installation and monitoring methods.

According to official case studies released by Aalborg University, the system developed by Pilar combines cloud-based software and intelligent installation equipment. During construction, sensors mounted on the screwing equipment record key parameters in real time – such as penetration rate, downward pressure, and torque. This data is instantly uploaded to the cloud and, through a dedicated calculation model, converted into load-bearing capacity documentation compliant with Eurocode 7.

This breakthrough has a dual significance:

Efficiency Revolution: Traditional concrete foundations require a curing period of 3-4 months, whereas screw pile foundations can be installed within a single day, and the superstructure can be built immediately the next day.

Environmental Friendliness: Data shows that compared to traditional concrete foundations, screw pile foundations can reduce the carbon footprint by up to 85% (for a 150 m² family home, this equates to a reduction of approximately 3,784 kg CO₂ equivalent). Moreover, as no excavation is required, they greatly conserve increasingly scarce sand and gravel resources.

Adaptation to Climate Change: New Applications Within the Arctic Circle

Beyond commercial breakthroughs in civil construction, academic research in 2023 also opened new frontiers for screw piles. As global warming threatens infrastructure due to thawing Arctic permafrost, a paper published in the journal Applied Thermal Engineering validated a new technique using hollow galvanized screw piles for artificial ground freezing (active cooling) . By circulating liquid coolant through the hollow piles, the system not only maintains the load-bearing capacity of the piles themselves but can also actively lower the temperature of the surrounding permafrost to meet the engineering challenges posed by climate change.

Industry Outlook: From "Niche Choice" to "Mainstream Solution"

In countries such as New Zealand and Iraq, research into screw pile applications also made substantial progress in 2023. Experiments demonstrated that under complex geological conditions like multi-layered clay or seismic zones, the lateral load-bearing performance of screw pile groups (clusters of screw piles) far exceeds that of traditional straight piles. Notably, when spacing is optimized (e.g., at a distance of 4.5 times the helix diameter), lateral resistance can be increased by nearly 64%.

Industry observers note that 2023 marks the "year of legitimization" for the screw pile industry. With the establishment of precise calculation models and the deepening embrace of eco-friendly construction concepts, these once-marginal galvanized steel piles are rapidly becoming an indispensable core component of modern sustainable architecture. They not only support the weight of buildings but also underpin the future of the global construction industry's green transformation.
