In conversation with Oswald Holzner

HB often describes its work as “shaping the world through numbers.” What does this idea mean to you?

“Engineering is, in many ways, the art of defining space through numbers. Behind every structure there is a silent language made of calculations, relationships and forces that cannot be seen but can be understood. Numbers allow us to reveal what is invisible and to guide matter through space and time.
For me, calculation is not only a technical instrument but also a form of expression. It is a compass that allows us to transform abstract ideas into tangible structures. Every equation contains a possibility: the possibility of turning imagination into reality.
In this sense, engineering becomes a journey from idea to built form, where art and science meet. A project often begins with a formula, but it ends with a space that people experience and inhabit. Our role as engineers is to give shape to the future through precision of thought, intuition and the quiet strength of numbers.”

HB was founded in 2010. What was the original vision behind the company?

“When I founded the company in 2010, the idea was to build an engineering practice based on methodological rigor, pragmatism and a deep understanding of structural behavior. From the very beginning we focused on structural and geotechnical design, studying carefully the interaction between ground and structure.
One of the key elements that shaped our approach was Value Engineering. We always believed that engineering should not only solve technical problems but also optimise resources and create efficient, sustainable solutions.
Over time, our work on soil–structure interaction, post-tensioning techniques and suspended structures allowed us to develop advanced expertise and apply it to increasingly ambitious projects. Step by step, this experience built the foundation of our reputation and enabled us to take on more complex and diversified challenges.”

Engineering is often described as a dialogue between earth and form. How do you interpret this relationship?

“There is a hidden energy that supports every construction. You cannot see it directly, but you can feel it in the way a bridge challenges gravity, in the way a building responds to the wind, or in how a structure and the ground beneath it find a natural balance.
As engineers we work exactly in that subtle dimension where imagination meets physical reality. Knowledge is never static; it evolves, adapts and anticipates change. Each project is an opportunity to combine the solidity of engineering tradition with the exploration of new possibilities.
Calculation is the thread that connects everything. It is the moment when thought becomes structure and resistance. But engineering is never only about numbers. It is about balancing opposing forces and finding harmony between elements that might initially seem incompatible.”

Behind every structure there is a silent language made of calculations, relationships and forces that cannot be seen but can be understood.

How do collaboration and dialogue shape the development of your projects?

“Every project begins with dialogue. Engineering cannot exist in isolation; it is the result of continuous exchange with architects, contractors and clients.
Through this dialogue we search for the right balance between aesthetics, functionality and economic sustainability. Our goal is always to ensure that a project is coherent with its context, its budget and its timeline while preserving the original architectural vision.
These collaborations have allowed us to work on a wide variety of projects, from infrastructure to industrial buildings and complex civil structures. Each experience expands our horizon and pushes us to develop new solutions and applications for materials and design methodologies.”

HB is known for integrating advanced technologies such as BIM and parametric modelling. How do these tools influence your work?

“Technology has transformed the way we design and understand structures. Today we integrate BIM processes, Life Cycle Assessment and parametric 3D modelling to gain a comprehensive understanding of every project.
These tools allow us to analyse the construction process in greater depth, optimise time and costs and evaluate environmental impact from the earliest stages of design. Technology does not replace engineering thinking, but it enhances our ability to explore solutions and anticipate potential challenges.
For us, innovation is not simply about adopting new software; it is about using these tools to improve the quality, efficiency and sustainability of the projects we create.”

What makes HB a unique place to work?

“The real strength of HB lies in its people. Over the years we have built a solid organisational structure supported by highly qualified professionals who share a passion for innovation and a commitment to excellence.
At the same time, we have always tried to cultivate a strong sense of belonging within the company. Every collaborator contributes to the development of our projects and to the growth of our collective knowledge.
Engineering is often perceived as a purely technical profession, but in reality it is deeply collaborative. Ideas emerge through dialogue, through the exchange of perspectives and through the shared ambition to create something meaningful.
For me, this is the true spirit of HB: a place where experience and innovation meet, where numbers become structures, and where people work together to imagine and build what does not yet exist.”
