The first step in this phase was the preparation of the project documentation, which was the basis for the start of construction works. The second step included dirt works, and connecting to required utility infrastructure (water, electricity, gas, sewage), then the installation of the power cable, pipeline, gas pipeline and drainage channel. After the completion of installations, underfloor heating pipes were installed, which enable uninterrupted operation of the car wash in all weather conditions. In this phase, after the completion of all installations, the concreting of the slab was done, together with the construction beams for the robotized car wash.
