More than just a place to work at

STRABAG is constantly developing the construction of the future, not only for our clients, but also for our own projects, which focus on sustainable and future-proof solutions, methods and innovations. On the campus in Stuttgart, we are currently building a new office building that will set standards not only in terms of sustainability.

ZÜBLIN, the STRABAG Innovation Department (SID) and STRABAG Real Estate (SRE) are joining forces at Albstadtweg 10 to realise the full potential of this new six-storey building. In addition to focusing on energy and resource efficiency, special attention is paid to innovative solutions and methods as well as pioneering work spaces.

Sustainability

Starting with green façades, CO2-reduced concrete and reinforcing steel, recycled aluminium and Cradle to Cradle (C2C)-certified fully recyclable materials, through to a consistent low-energy operating concept and almost self-sufficient power supply from photovoltaics: the new building called Innovation Center is a pilot project for using climate-friendly construction materials and technologies.

Innovation & Digitalisation

The Innovation Center in Stuttgart is a flagship project in many respects. In all phases, from initial planning to construction and operation, the STRABAG Group relied on digital working methods and innovative tools:

Building Information Modeling
All project participants used Building Information Modelling (BIM) and worked together on a continuous model across all service phases via the BIM 360 project platform. The construction project was used as a BIM pilot to apply and further develop in-house standards and new solutions.
As-built-Modell (structural works)
By means of laser scanning, the built geometry is recorded and compared with the structural model of the construction design. Any deviations can thus be considered for further planning.
Modularisation of building services
Cross-trade building services modules were designed, prefabricated, delivered and assembled in one piece in the building. This approach reduces the execution and assembly time on the one hand, and on the other, saves storage space on the construction site and minimises idle time. Industrial prefabrication achieves a significant increase in execution quality. As a result, the number of assembly crews on site can be decreased, ensuring clarity and safety on the construction site.

Prefabricated building services ceiling modules from SIEGLE + EPPLE make installation noticeably easier and faster while saving storage space and reducing idle time on the construction site.

Quality control with Augmented Reality
Quality control of reinforcement was carried out using augmented reality (AR). The reinforcement model is superimposed with the actually installed reinforcement, enabling a visual comparison. In this way, discrepancies and agreements can be recognised quickly and easily.
Rule-based verification of user requirements
With the rule-based verification of geometric and alphanumeric project information, compliance with selected structural engineering codes can be checked. Rule-based model checking tools were developed and applied for coordination services in the project.
3D reinforcement design
The 3D reinforcement model offers numerous possibilities to apply downstream processes. This allows collision checks with other components at an early stage in order to increase the design quality. There was also a quantity control of the reinforcement in comparison to the calculated and the planned steel quantities. The 3D reinforcement model is also used for building documentation.
Mobile daily site reporting (sitelife)
Daily construction reports were created with the “sitelife“ platform. The platform offers the possibility to provide building components with information about their state of construction, to display them visually and to evaluate the construction progress in ITWO 2021. The daily site reports can be recorded digitally with mobile devices and daily weather data can be stored automatically.
Digital fire safety file
By using a digital work platform, seamless fire protection documentation is provided. It also contains all relevant information on the various fire protection measures and enables plan- and model-based processing of each individual measure.

Modern office spaces

Along with high sustainability standards, innovative solutions and a consistently high standard of technical equipment, the main focus of the new building is on people. The standard floors are optimally adapted to the needs of employees for working in a modern office concept with desk sharing and no permanent work areas.

The Innovation Campus on the third floor of the new building is a source of inspiration for the entire location. Collaboration, innovation and contemplation converge here in a central location on around 20 per cent of the floor area available to all users of the building.

Since October, the Group Units STRABAG Innovation & Digitalisation (SID) and STRABAG BRVZ IT have moved into the Innovation Center. A total of around 400 employees are now working on progress together under one roof – in keeping with the Group’s motto Work On Progress.
