In order to be able to coordinate the concreting in the best possible way, the call-offs are made using a digital application. The delivery rates can be coordinated with the concrete pump, particularly for large-scale concreting, thus reducing the waiting times of the concrete mixers. Production times are optimized and noise emissions are reduced.

The Lean Last Planner system is used for the shell construction work. This includes the continuous detailed planning of a daily forecast for the next three weeks (3-week forecast), as well as a weekly forecast every three months. Meetings are also held twice a week. Changes in the construction process can thus be incorporated directly so that they can be better controlled and carried out efficiently. As a result, reorders and new orders can be reduced.

The project is located on a large campus site, so the aim of the construction site is to minimize the impact on the university's students and employees as much as possible. Various measures are planned, which can be distinguished on the one hand by the selected construction methods and on the other hand by the organization of the processes.

In order to keep noise emissions and vibrations to a minimum, alternatives to the original construction methods were investigated. For example, the shocks, vibrations and noise emissions that would have been caused by the planned pulling of the shoring beams were reduced to a minimum by burning off the beams and leaving them in the ground.

It is planned that all motorized equipment and machinery used on the construction site, e.g. earthmoving equipment, compressors, etc., with an output of over 75 kW will be documented and the EU level (energy efficiency class/EEK) they meet will be recorded to ensure that the most energy-efficient construction machinery possible is used.

The waste disposal concept provides for the respective subcontractor to dispose of its waste in floor collection stations. The waste disposal logistics company then takes over from these collection stations and removes this waste from the building to the waste disposal containers located on the construction site. This ensures that waste is disposed of according to type.
