Digital Sensor-Based Prevention Assistance for the Avoidance of Stress Hazards in the Building Trade
Digital assistance systems support the skilled trades
Employees in the building trade, such as painters and plasterers, are often exposed to severe physical strain that can lead to illness and absenteeism. The reasons for this are often working environments that are not ergonomically designed or unconsciously incorrect postures on the part of the employees. Despite the assessment of hazards by the company and instruction of the employees, the physical strain on the employees is usually not taken into account when planning the work. In order to be able to work long and well in the building trade, physical stresses that are harmful to health must be recognised and reduced preventively. The new development of the lightweight, portable sensor network aims to optimally record data on physical strain caused by non-ergonomic postures, for example.
Aim of the research project
The aim of the BauPrevent research project is the prototypical development of a practical, construction trade-specific sensor system for individual stress measurement that can be worn on the body (wearables) as well as a wearable-supported recommendation system for context-related prevention assistance of the craftsman. The system is to record the specific loads, carry out a risk assessment and integrate this into the work planning. In addition, it can provide the craftsman with helpful prevention advice if severe stresses occur during work. The painting and plastering trades are examined as exemplary implementation cases. Based on this, algorithms for evaluating the stress data are being researched, which enable a risk assessment. The project's own BauPrevent recommendation system uses these algorithms to determine preventive options for action. On the one hand, these can be used for deployment planning in order to reduce physical strain and to design work processes of the craftsmen in a preventive manner. In addition, the craftsman receives individual recommendations during the work process directly on wearables specially designed for this purpose, which inform him about his strain and make suggestions for avoiding long-term negative effects on his health. In addition to the technical aspects, the project is looking at the usage behaviour and acceptance of building contractors and building tradesmen. The sensor network will be prototypically tested by the participating crafts enterprises and evaluated by the research institution.
Social added value
The project results will be disseminated through associated partners at chambers of crafts and crafts associations at federal and state level, through networks specific to the building trades and through the project's own events. Findings, concepts, software and hardware modules are integrated or further developed in the participating companies. In the long term, the results are transferable to other building trades such as bricklayers and tilers as well as to other sectors such as the transport and logistics sector.
