As part of the reconstruction of the dilapidated D1 building in the Nová Zbrojovka complex in Brno, we provided the supply and installation of lightning conductors, power and low-current systems, including the relocation of a 100-year-old crystal chandelier. The original building was largely preserved, but it was necessary to bring the outdated wiring into the 21st century. The upgrade took several months and included new lightning rods, new switchgear, new lighting, complete new structured cabling, security and alarm systems.
