We are Bollinger+Grohmann

We are engineers driven by passion for high-quality architecture, sustainable solutions and technical innovation.

This passion has motivated Klaus Bollinger, Manfred Grohmann, and their team since the company’s foundation in 1983.

Over the years, we have had the opportunity to work on exceptional projects with inspiring collaborators whose ideas challenged us to continuously excel at our work in structural engineering, façade engineering, building physics and fire engineering. Today, we reside in 20 offices in ten countries across the world.

Development

Our objective is to strengthen and enhance each design

Our interdisciplinary design approach integrates architecture, building technology, and construction, creating societal and economic value for our clients and society.

Likewise, the diverse skills of our team allow us to develop tailored solutions with architects, clients, construction companies, and the industry.

Our prime focus is the strengthening and enhancement of each design brief by bringing inspiration, innovation, efficiency, and sustainability to every project and process we engage with.

Sustainability

We promote responsible and creative engineering

Our task is to establish a process to deliver functional, technical, and aesthetical structures while achieving high sustainability goals.

With our commitment to careful analysis of the environmental effects in each project phase, we aim to reduce environmental impacts by any means possible through a creative and sensible approach to the projects.

Proof of concept

We implement innovative concepts and continuously research to be better engineers

Ongoing studies with high-level research projects provide valuable feedback that lays the groundwork for our approach to each new project. These pilot projects aim to impact the building industry and set new standards for sustainability in planning and construction.

We see implementing innovative concepts into engineering praxis as an elementary part of our work and encourage the development of solutions within the team and with external collaborators.

Collaborations

We are partners within an interdisciplinary planning and design team

Our goal is to deliver efficient engineering for complex briefs and multi-layered challenges. Our clients and collaborators can rely on our company’s international experience and network of engineers.

In addition to environmental concerns and resource-conscious design, we regard healthy project finances, social responsibility, technical excellence, and good craftsmanship as fundamental elements of our work.

Teamwork

We are an accomplished international team with projects across the globe

Our team comprises talented structural engineers, architects, technical drafters, and office support, who add a manifold of skills and knowledge to our work and culture.

Development of individual skills is encouraged and supported through internal education and training that focuses on technical excellence and communication exchange. With meaningful in-person and digital cross-office collaborations and our internal ‘B+G ERASMUS’ program, we strive to improve knowledge exchanges, workflows, and project deliveries.

Innovation

We support growth through innovation, research, and development

We are passionate supporters of research and learning, with many of our team members teaching at respected institutions worldwide.

We regard individual development and research as an essential part of individual and collective growth; hence, supporting the spread of innovative ideas improves not only our workflow but also the workflows of the construction industry.
