BIM coupled construction machine tool requirements when using machine-based non-stationary processes to verify construction progress

Project Description

The construction industry is one of the least digitized sectors and is characterized by a below-average increase in productivity in recent decades. The imminent shortage of skilled workers in particular is putting further focus on the efficient handling of construction processes. In resource-intensive civil engineering, construction machines - in particular their attachment tools - provide the central added value. The increased requirements due to growing complexity are also noticeable in the logistics of the construction industry. Research shows that there are helpful solution approaches such as lean management or construction machinery fleet management, whereby the attachment tool has been neglected and has not played a role so far. A systematic classification of attachment tools is missing so far in order to assign condition and process data. Recording the use of attachment tools can make the productivity and quality of execution transparent through the construction progress.

Up to now, there has been no comprehensive investigation of the possibilities of sensor technology upgrades for attachment tools in combination with the carrier machine in order to optimally capture machine construction processes under the given boundary conditions. Likewise, the design of a modular and expandable hardware/software architecture including interface definition is a challenge. Digital BIM planning as a central platform can serve to coordinate and process this information using suitable algorithms. On the one hand, this can support the operator during machine operation, and on the other hand, the back office can track the construction progress with the help of "as built" manufacturing feedback as well as remotely determine the tool status. All in all, this holistic approach to attachment recording offers SMEs in particular the opportunity to participate and contribute to the trend of digitalization in the construction industry.

The approach of upgrading add-on tools enables a low-effort start. The ToolFlott research project will investigate the research question of how attachment tools, as a key interface of construction logistics between planning and construction, can contribute to the effective and efficient handling of construction projects through the use of digital technologies. To investigate this research question, the following three sub-objectives will be pursued:

  1. Increased planning quality in construction logistics through precise prediction of tool wear and BIM-coupled construction progress;
  2. More effective construction through informational integration of the construction equipment operator and feedback of information of construction activity and quality to the back office;
  3. Improvement of the entire information logistics through information technology integration of the attachment tools into the construction process
