Careers - Your path to GRASSL

Working at GRASSL means paving ways. And that means accepting challenges together to create better connections for everyone: by producing intelligent, innovative, visually pleasing and functional building structures. We are looking for people who value diverse teams and like to work collaboratively. Open communication is essential for challenging project requirements to be translated into sustainable structures.

Progress at the Güsen railway overpass project

We have just completed an exciting milestone

The first track closure has been concluded successfully. In just two weeks, the deep foundation of the abutments, the construction pit walls and the auxiliary bridges were built – a big challenge which was mastered skilfully by the team of the construction firms.

Tatenberg Bridge

Progress in the construction of the temporary bypass

Work on the ramps of the temporary bypass of the Tatenberg bridge has been completed. The sheet piles have been pressed into place and the concrete roadway slab has been concreted. What are the next milestones and challenges?

It’s a wrap!

An exciting project on the A1 highway has been concluded successfully

The construction work on the route guidance systems (SBA, Streckenbeeinflussungsanlagen) on the A1 highway has been completed! In total, foundations were concreted at seven locations, supports were installed and barriers were lifted into place.

WIDE RANGE OF SERVICES AND METHODS

Interdisciplinary collaboration allows GRASSL to offer a wide variety of services in the field of civil engineering. Our services cover design, checking, supervision and maintenance, as well as digital planning and structural health monitoring.

PERFECTLY PLANNED

We think holistically, from the determination of the requirements to the completion of the project, as the characteristics of one structure are always different from the next. Experience, methodological knowhow and interdisciplinarity are essential ingredients for creating perfectly tailored solutions. By choosing GRASSL you benefit from seven decades of successfully planning civil engineering projects.

STANDING THE TEST OF TIME

To create structures that are both durable and safe, it is a definite advantage to collaborate with our checking engineers. We specialise in the areas of structural, welding and fire safety design checking. Our vast experience in planning and assembly feeds back into our testing procedures and vice versa.

CONSTRUCTION SUPERVISION

The supervision and monitoring of building projects requires a significant amount of resources. GRASSL can give systematic advice and lend support – by providing production supervision, local construction supervision or work health and safety coordination. You could also do it yourself, of course. But you don’t have to.

NO TWO CRACKS ARE ALIKE

To assess the risks of structural damage, solid experience in the design and execution of structures is required. Each year, GRASSL carries out the structural assessment of around 300 bridges, tunnels, hydraulic structures, buildings and special structures. Relying on scientific methods and structural health monitoring data, we can also provide analyses of specific damage and structural assessment of structures, as well as determine their remaining service life. Last but not least, our digital structure management system allows us to offer maintenance and operations management services. Prevention is better than cure.

CIVIL ENGINEERING 4.0

The buzzwords of the digital age are networking, cooperation, virtualisation and vividness. Thanks to digitalisation, formerly tedious processes can now be executed faster, better and more efficiently. GRASSL lives and breathes essential services such as building information modelling (BIM) or structural health monitoring and is pioneering BIG BIM in a number of structures. For civil engineering 4.0, we connect the best of the old and the new: boldly, collaboratively, consistently.
