Successful conclusion of the BMBF-funded project ConWearDi

The ConWearDi project dealt with the development of a web platform based on Industry 4.0 technologies. That enables a digital exchange of information between all parties involved in construction and implements intelligent planning and control services as well as continuous quality assurance and documentation processes.

Connecting smart materials to the ConWearDi platform

This ConWearDi platform offers various services, from reporting and scheduling to cost/benefit calculations. In addition, it has a project database and a sensor database. On the one hand, this provides real-time planning, real-time management and real-time customer support. On the other hand, the construction site workers are assisted in real time, whereby the cognitive load and acceptance were also investigated and evaluated in the project.

In addition to the above-mentioned ConWearDi platform, an intelligent spraying machine and an intelligent safety helmet were also developed within the framework of the research project, which ran for 3 years. The spraying machine has an integrated sensor system that automatically presets the recommended spraying pressure on the machine and, for example, provides recommendations for the use of different spraying nozzles. The intelligent safety helmet is designed to support occupational safety on the construction site. It is equipped with sensors and actuators and thus enables the early detection of safety-endangering influences.

The main focus of DAW's work in this project was on the development and networking of intelligent building materials with the aim of avoiding structural damage and improving communication between the building trades on the site during the construction phase. The intelligent building materials provide dynamic information about their condition (humidity, temperature), identity and properties at any time during the construction phase as well as in the long-term use phase. This Information is automatically transferred to the ConWearDi platform and evaluated with artificial intelligence. Materials that can be considered are insulation, plaster, paint, etc. The functionality and performance of this intelligent system could be analysed and further developed in several case studies (concrete building projects) within the framework of the project. The final result is an optimised sensor system with a connection to a cloud box for the automation of sensor reading process and transmitting data via the internet. Thus it contributes to a smooth process on the construction site and to improving the value retention of the building structure.
