Hagerbach Test Gallery (VSH) Recognized as ‘Research Infrastructure of National Importance’

The Swiss government has officially recognized the Hagerbach Test Gallery (VSH) as a research infrastructure of national importance. This recognition is a testament to over 50 years of innovation and contribution to underground research. The funding associated with this designation will support the development of new research infrastructure, benefitting partners such as EFNARC.

Originally established as a test gallery, VSH has evolved into a comprehensive research facility, laying critical foundations for EFNARC's work in setting industry standards.

History and Importance of Hagerbach Test Gallery for EFNARC

Researchers and developers from all over the world use Hagerbach’s research facility to conduct cutting-edge research, training, and large-scale testing across 25,000 m² of tunnels, laboratories, caverns, and test fields. VSH has hosted the EFNARC Nozzle Operator Examiner Training since its inception, providing an optimal environment for technical training and certification.

Additionally, the EFNARC office has been located at VSH in Flums for the past three years, reinforcing the strong relationship between the two organizations. “The collaboration between VSH and EFNARC has played a pivotal role in developing and refining industry standards,” says Michael Kompatscher, Managing Director of VSH.

The training and research facility in Hagerbach serves as the foundation for the Nozzle Operator Examiner Training, setting global standards in a well-suited environment. The first TBM pilot training also recently took place at VSH, further demonstrating its role in advancing tunneling technologies. The course aims to equip TBM operators with the necessary knowledge and skills to perform their tasks in a safe, high-quality, and cost-effective manner.

Michael Kompatscher has been the Managing Director of VSH since 2017 and attended the first EFNARC meeting in the same year. He is also involved with the International Tunnelling Association Committee for Education and Training (ITACET), where he leads Activity Group 2 on industrial training for blue-collar workers and drives the ITA global training initiative. Additionally, he serves as the EFNARC Secretary, an Executive Committee Member, and the leader of Focus Group 5, which develops testing methodologies and standards for fire protection systems in tunnel construction.

The Significance of National Recognition for VSH

Michael emphasizes that the new recognition underscores VSH’s role beyond its traditional industrial focus, highlighting its increasing significance in scientific research. "This recognition positions VSH in a new light." While we have always worked closely with the industry, we are now equally engaged in high-level scientific research, which requires meeting entirely different standards," he explains. This shift integrates VSH into an ecosystem that includes ETH Zurich and EMPA, fostering breakthroughs at the intersection of research and industry.

Michael highlights that the federal contributions will help cover part of the running costs and investments in VSH’s research infrastructure. "These contributions are beneficial for the researchers at the center as well as for partners from industry and universities who carry out their research activities here at the technology transfer interface," he explains.

Furthermore, he considers the recognition a significant image boost: "As a research environment recognized by the federal government, we are generally more attractive for researchers who want to develop their research topics in the long term." He expects the recognition to attract further research projects, facilitate investment, and strengthen VSH’s position as The underground Future Lab.

Planned Investments in Shotcrete Research and Training

The funding associated with the national recognition allows for critical investments in new and replacement research infrastructure, creating further opportunities for research into advanced techniques such as autonomous robotic sprayed concrete applications.

This project aligns with European Horizon initiatives, making VSH a prime location for innovation in underground construction. "We are driving forward the development of sensor and measurement technologies related to shotcrete rebound, pulsation-free spraying, fiber technology, durability monitoring, and structural health assessment. This will allow us to push the boundaries of efficiency, sustainability, and quality control in tunneling," Michael notes.

Michael also emphasizes EFNARC’s role extends beyond sprayed concrete certification, as it is a broader industry association dedicated to setting new standards. "EFNARC is not just about shotcrete—our mission is to drive innovation across the tunneling sector, addressing key areas like sustainability, digitalization, and automation," he states.

The use of simulation technology in personnel certification further highlights VSH’s and EFNARC’s commitment to providing state-of-the-art training and research environments.

The Importance of Partnerships for VSH

EFNARC and its members have played a crucial role in VSH’s success, shaping the organization into what it is today. Long-standing partnerships have fostered close collaboration with employees and industry leaders, driving innovation and progress in underground construction research and training.

"Strong partnerships are the backbone of our success. Working hand-in-hand with EFNARC and our industry partners has enabled us to create meaningful advancements that benefit the entire tunneling community," says Michael.

These partnerships remain essential as VSH continues to expand its capabilities and influence in the field.

BarChip Joins EFNARC as a Full Member, Reinforcing Their Commitment to Fibre Reinforced Shotcrete

BarChip has been the latest member to join EFNARC, further strengthening their position as a leader in fibre reinforced shotcrete (FRS). BarChip has a long-standing commitment to advancing sprayed concrete technology, improving industry standards, and supporting best practices in shotcrete construction. For three decades, BarChip has pioneered the use of macro synthetic fibre reinforcement, delivering high-performance solutions across global mining and infrastructure projects.

Fibre reinforced shotcrete is at the core of what BarChip does, and for over 15 years, the company has provided EFNARC Nozzle Operator Certifications to clients and industry alike. Becoming a full EFNARC member is the next step in BarChip’s ongoing mission to drive innovation and enhance quality in the industry.

Des V., a certified Nozzle Operator Examiner, represents BarChip within EFNARC. With extensive experience in sprayed concrete applications, Des has joined the Fibres for Concrete and Nozzleman Certification focus groups, and will contribute to EFNARC’s efforts in training, certification, and industry development.

“BarChip has always been committed to the advancement of fibre reinforced shotcrete, and joining EFNARC as a full member is a natural step forward,” said Des. “We look forward to working alongside industry leaders to continue developing standards, training programs, and innovative solutions that benefit the entire construction sector.”
