Freeform

Maximum freedom in form and space

With its airy and seemingly floating appearance, it is one of the supreme disciplines of architecture: the freeform steel and glass supporting structure is unmatched in its ability to envelop large areas in a unique way.

However, the more demanding the structure, the more important meticulous planning in advance becomes. The development and implementation of our fascinating unique pieces is a multi-stage and highly complex process: Through very close cooperation between the architect, specialist planners, and GIG, freeform surfaces with character emerge.

Making the concept feasible

The process begins with the architect’s design, where the vision and basic concept for the freeform structure (e.g., for a roof construction) are developed. At the same time, an initial static calculation is prepared. After initial calculations regarding the load-bearing capacity and stability of the structure, the predefinition of spans, glass sizes, and divisions begins.

From plan to detailed concept

The next step involves developing the geometric form of the freeform structure and refining the support system. Using specialized software and techniques, the desired shape is modeled and detailed. We analyze whether the surface can be described with triangular glass or square glass panes. As a crucial step, we develop a suitable node connection.

Large-scale glazing

Depending on the architectural style and taking into account the respective building regulations, countless possibilities of glazing systems can be implemented. For this, we analyze the position of the glass panes in relation to each other to use a suitable sealing system and plan drainage and ventilation.

Understanding the uniqueness

Freeform support structures are special constructions. To make the ideas tangible, we create an initial prototype. In consultation with our clients, we build a section of the freeform structure to scale or full size to verify the feasibility and precision of the construction. Any further adjustments and optimizations are also made at this stage.

Checked down to the smallest detail

Due to the very individual execution of freeform constructions, tests for tightness or the load-bearing capacity of the system are often required. For this, we create our own test samples.

 Completion of the whole

After completing the development and testing phase, the actual production of the freeform structure takes place. Through our manufacturing and assembly expertise at GIG, we develop an exact production plan considering the conditions on the construction site. Prefabrication in segments are often done to increase the precision and quality of execution and to shorten the assembly time.

The assembly of the structural elements and their glazing requires experienced craftsmen. Assembly logistics are a crucial success factor. Therefore, together with the technical development of the structure, we also develop an assembly concept. Ongoing monitoring during assembly by our team is essential to achieve a perfect end result.

At the end of this process, there are satisfied architects, clients, and GIG employees. And with each project, we increase our experience and competence to make the next project even better.

Our Expertise for your Freeform-Facades

Freeform load-bearing structures made of steel and glass give large surfaces a floating lightness and create extraordinary architectural highlights. Through precise planning and close collaboration with architects and specialist planners, we at GIG realize each project as a custom-made unique piece – from the initial sketch to the installation.
