Civil engineering structures, such as road traffic and railway bridges, have, as a rule, a lifespan of about 100 years. However, over the past 30 years, the traffic load has increased enormously in Europe and throughout Germany, in particular heavy-duty road traffic. At the same time, some construction methods and the materials employed are now considered out-dated. In addition, there are the damaging environmental influences, and, furthermore, infrastructural measures were to some extent neglected.
The central task of our structure monitoring procedure are the precise description and analysis of the deformation behaviour of a civil engineering structure during the realistic, in other words day-to-day traffic load in conjunction with its dead weight and all other relevant external influences.
In order to obtain informative data about the structural condition of a civil engineering structure, we measure the deflection and the ductility while being exposure to load. This means that changes in the load-bearing behaviour can be reliably identified.
The goal is to achieve the long-term and safe use of the civil engineering structure. To this purpose, we continually analyse and evaluate all collected data. Based on these expertises the necessary steps can be taken.
Permanent structure monitoring is an independent service. It abbreviates the technological decision-making processes and improves the planning security for the operators of the civil engineering structures. This impacts not only the scope (and so also the duration and the costs) of a rehabilitation or constructing a (new) replacement building, but rather also the entire process management system, which includes the construction site and traffic planning for the duration of the necessary building measures.
On the strength of the determined data, the engineers and inspectors that are responsible for the civil engineering structure can accurately gauge in what time range and on which specific date necessary maintenance or construction measures must be taken.
The patented measurement technology employed by BMG for permanent structure monitoring was developed by Lucks Technologies GmbH in Hamburg, Germany. We conduct research in close collaboration with the faculty for Natural Science, Technology and Medicine (FTSM) of the University of Luxembourg in order to ensure that those responsible for civil engineering structures and the operators of such structures have greatest possible security. At the same time, we are also able to continuously improve our measuring method.
Since the beginning of 2020, we have been conducting an on-site element test for stress corrosion cracking (SCC).
