Construction of foundations for lightning protection system at a photovoltaic power plant near Dobrich

Building company Varaks Construction has carried out the construction works for the foundations of lightning protection rods at a photovoltaic power plant in Dobrich area. The works cover site preparation, foundation construction and all necessary activities to ensure the strength and stability of the foundations.

The construction stages include:

• Excavation for the lightning protection rods foundations, including manual shaping of the excavation and temporary storage of excavated soil on site;
