Project Work

Customized Solutions
Our engineering service and development projects present customized solutions tailored to your needs, so that you will not have to settle for standard-solutions. Generally, the projects are prepared and co-ordinated in the course of personal discussions between your and our teams of experts.

Efficiency, Promptness and Cost Control
Our highly skilled and professional staff members - who are known for their personal willingness and devotedness and their ability to encapsulate technical questions - present our main resources and allow for the most efficient processing of your projects, which in turn saves time and money.

Depending on the type of the project and according to your wishes our partnership can be designed in form of a

  • package on a fixed price basis
  • framework offer
  • development partnership.

Thus, it is guaranteed that you always obtain the optimum solution - also from a financial point of view.

State-of-the-Art Project Communication
In order to configure co-operation processes most efficiently we have prepared a Web Conference application by means of which your and our experts can discuss and co-ordinate even the most complex matters on the screen. This saves travel expenditure, but is as efficient as a face-to-face conference.

  • Your advantage: No expenses for you. All you need is a telephone and an internet browser.
  • Your access to our Web Conference System:


SBETA-AT - Finite-Element and Optimization Software

Non-linear Simulation of Concrete and Reinforced Concrete. Today unconventional architecture and particularly the cost aspect require the reliable assessment of ultimate states of concrete and reinforced concrete.  Also including stochastic methods, Cervenka Consulting (CC) has developed SBETA-AT, which is a FEM-program specialized in the non-linear simulation for crack propagation, stability and structural failure of ...

IMMI - Air Pollution Mapping

IMMI covers a wide range of applications ranging from noise mapping to air pollution modelling. IMMI integrates both noise and air pollution in a single software package. In this section we will concentrate on the features of IMMI that were specifically designed for air pollution mapping and dispersion modelling. With its modular design and price-list, IMMI can be adapted to user's needs and budgets - ask for details!  IMMI ...


ADD.Pipe - Piping Vibrations System

Conventional methods for the reduction of vibrations in piping systems often require a rather intense intervention in the piping system, causing high effort in terms of construction, time and money. In order to circumvent the problems mentioned above, Wölfel developed the ADD.Pipe®, an Active Pipe Vibration Absorber, which strongly reduces pipe vibrations in a broad frequency range. The ADD.Pipe® („ADD“ ...

Wireless Measuring System

Wind turbines are built on more and more locations – which makes an issue out of noise emission. The international standard IEC 61400-11 and the German “Technische Richtlinie für Windenergieanlagen, Teil 1” of the FGW were set up to unify the evaluation of noise emission. Measurement of noise emission according to these standards is linked to formidable challenges – particularly for the ...


IMMI Aircraft Noise Training

The trainig course concentrates on the specific features of IMMI for aircraft noise mapping. The course covers every aspect from data input to export / print-out of final results. Due to the specific nature of the geometry of flight paths, the changes in noise emission of the moving source, the large variation in noise sources (i.e. the large number of aircraft operated on airports) and the long distances that must be taken into consideration, aircraft ...

IMMI Environmental Noise Mapping Training

The basic training that is presented on this page is targeted towards new users of IMMI. This training helps in developing a confidence in using IMMI in projects. Advanced training 'noise prediction & noise mapping. Advanced trainings can be arranged on demand. Advanced trainings are targeted towards specific user needs and require a certain level of acquaintance with IMMI. Advanced trainings do not follow fixed structures but are tailored towards the ...
