Digital Work Preparation Tool for Underground Construction Tasks—Planning and Optimizing Projects - RETC2023

The demand for sustainable and profitable/efficient projects within the tunneling and other underground engineering sectors grows rapidly. Construction tasks play a key role within the project conduction, whether as primary (tunneling), secondary (e.g., mine securing) or tertiary processes (e.g., workshops). The construction tasks of primary processes create the main structures, such as tunnels, which resemble the main project goal. For the secondary and tertiary processes, the purpose of the task shifts. The main goal is to provide structures, such as the securing of the cavity and workshops, that enable the project and enhance the efficiency of the primary conduction underground. To plan and optimize the conduction of construction tasks underground, whether they are identified as primary, secondary or tertiary tasks, the work preparation can be used. This method, known from the above ground construction, can be adapted and used underground. The approach of a digital work preparation tool combines, connects and adapts the main tasks “choice of procedure,” “logistics” and “site planning.” In addition, the digital tool is connected with digital models (construction, site, surroundings). With the adaption and forward projection of the work preparation, underground constructions (e.g., tunneling) can provide a more sustainable and efficient outcome.
