The VBI consists of an extensive network of interconnected groups and associations inside and outside of Germany.  In order to ensure the efficiency of various areas of consulting and planning within VBI, 14 specialized technical groups act as competent experts on all technical and economical areas.  Due to the variety of advanced training experiences within these technical groups, the VBI enjoys great professional diversity.

Our specialized technical groups are:

• Construction Engineering – This is the largest technical group within the VBI, and therefore also the most crucial aspect when beginning to develop a project.  The engineers inspect and plan everything from load capacity to bridge constructions, always keeping safety and efficiency as a high priority.
• Technical Equipment (heating, ventilation, sanitary) – The techical installations within a building, such as air conditioning, heating, and ventilation, are important to raise the quality and the efficiency of projects.  The engineers in this technical group develop optimal living conditions for specific facilities, such as sanitation equipment in swimming pools, schools, etc, while keeping in mind the issues that may arise with certain installations.  The development of technical systems with high quality and optimal costs also ensures sensible energy use, which in turn helps conserve environmental standards.
• Water and Disposal Management – The flow and disposal of water in buildings and infrastructure is vital for everyone, and effective planning from this technical group assures that water is correctly transported, treated, and stored.  This group plans and develops optimal water storing facilities for drinking water, efficient waste disposal systems, and the recycling and collecting of new water.  Engineers within these fields guarantee optimal advice and professionalism for the best solutions.
• Traffic and Surveying – Effective infrastructure also requires effective traffic planning and management.  This technical group uses its knowledge to develop creative and competent solutions for sensible traffic concepts, with surveyors acting as consultant and inspectors in all aspects of the development.  Whether it be the creation of an urban traffic system, the improvement of a bus system, or the planning of a highway, this technical group presents the optimal solutions.
• Acoustic and Thermal Building Physics - Many constructions require optimal acoustics for their respective uses, such as concert halls, theatres, conference rooms, etc.  This technical group determines the equipment and the construction methods necessary to fullfill this criteria, as well as to provide efficient noise and temperature isolation where necessary.
• Publicly ordered authorized experts – Impartial experts are often called in to give their professional opinion and advice on certain issues within the building procedures.  They act as consultants and inspectors in order to give competent solutions when needed.
• Electrical, Light, and Information Engineering – The electro-engineers in this group evaluate and resolve critical technical issues to find the most efficient solutions.  By developing experiences and knowledge in technology, sciences, and market development, this group creates effective electrical and technical installations necessary for the project being created.
• Geotechnics – When planning to begin a construction, one of the most important things that need to be considered is the building ground in itself.  This technical group determines its composition, its characteristics, and its potential problems, thus assisting in determining whether the ground is adequate for the building in progress.  This technical group also keeps in mind the environmental issues this construction may create.
• Architecture and Technics – This group encopasses a wide spectrum of themes related to efficient building, construction, and technical development of projects.
• Technical-Economical Management Consultancy – In this technical group the technical and economical aspects of a building are put into consideration by combining business consultancy with technical knowledge and expertise.  This way project developers are able to interact and merge in the industrial, insurance, and banking sectors for optimal contruction realizations.  
• Project and Facility Management – The engineers in this technical group offer advice and solutions for the effective realization of your projets by considering the optimal costs, yet creating the most effective contruction plans.  VBI members in this group are also concerned with developing optimal facility management in order to ensure the complete functioning of the building as a whole.
• Safety at Work and Occupational Medicine - The safety of a building site and of everyone involved in it is a high priority for this technical group.  Apart from performing building site inspections according to the occupational safety law, the occupational medicine area conducts preventive check-ups and offers medical assistance along with professional consulting in matters related to the development of specific projects.
• Natural Sciences – Seeing as natural resources and natural circumstances are vital for the development of a building, a strong knowledge in chemistry, biology, and ecology is necessary in order to determine the most efficient infrastructure and building procedure.  The expertise and professionalism of this technical group also ensures an evironment-friendly construction.
• Elevator and Conveyor Technique – The engineers in this technical group focus on the safest and most comfortable way to develop and integrate elevators and other conveyors into buildings and constructions.  By early collaboration with other architects and engineers, this technical group manages to ensure quick and reliable results at lower costs.
