Keywords: grouting with acrylates; construction process visualization; digital analysis; key performance indicators; productivity and cost analysis; predicting construction times The research project “Wireless data monitoring” deals with developing digital tools for construction sites in the field of special geotechnical works. Its goal is to optimise monitoring and data management. This thesis was written in the framework of this research project, and it deals with the digital analysis of grouting work. The eVALUATOR analysis tool is to be developed for this purpose, and it will consequently be utilised in grouting work on construction sites. For this project to succeed, it is necessary to develop such a tool in cooperation with practitioners who use it in their daily work. During a research visit to a construction site on which grouting work was being carried out, the foundation for this analysis tool was laid in cooperation with site staff. Besides gaining an understanding of the individual construction processes of grouting and the current monitoring and data management systems, the main focus was on ways in which a digital analysis tool might facilitate the work and which evaluations and forecasts could be made automatically. In order to give the reader a general understanding, this thesis begins with a short overview of groutings from the specialist literature before focusing in greater detail on groutings in tunnel construction. More precisely, subsequent groutings with acrylates aimed at sealing the excavationdamaged zones are explained using a specific example. What is critical in analysing processes is to understand these. This is how all the construction processes in the execution of grouting sealing in tunnel construction could be observed in field studies and later visualised and explained by using this specific project as an example. The eVALUATOR analysis tool is to be developed based on a state-of-the-art software tool for monitoring and for data management. This software tool is already being used on grouting construction sites, and it facilitates the work of site managers. Using the analysis tool developed, this data shall be utilised for determining specific key performance indicators, for productivity and cost analysis as well as for predicting construction times. This thesis creates the technical and economic basis to allow programmers to develop eVALUATOR. The focus is on how evaluations will be generated, from where the necessary input data will originate, and whether or not it needs to be imported into the system specifically.
