Facts and figures

The following figures are based on our own experience and operating procedures. We have already been working according to our construction system since 2017 and have continued to optimize the processes and people for the most economical operation.

Figures from 2022

Sample calculations and CO2 savings

The figures given are intended as an assistance and should give you the opportunity to make your own calculations based on the transparent presentation.

In addition to the cost aspects, the time benefits should also be taken into account. In order to minimize dependencies, our company has its own inloader trailer and a 60t crane at the production site. This allows us to achieve maximum flexibility and keep the added value in-house.

With regard to the assembly times given, it should be noted that not only the shell construction is included. The times also include the casting of the floor slab, the installation of the stairs, the suspended ceiling, the elevator shaft, and the prefabricated bathroom. Initial experience with a WMT customer shows that 1-3 projects must be completed in order to work similarly efficiently.

Final assembly

Apartment house with 6 residential units

The following figures refer to an apartment building with 6 residential units.

Base plate and shell construction with 3 employees 540 working hours
incl. Bathroom, stairs, elevator shaft, unfinished roof
Seal wall & ceiling joints with 2 employees 160 working hours

For the first floor, this example results in an increase in area of 5.2%, without taking into account the technical room (here 2.7 m²).
