Services offered: Examination and inspection of structures (e.g., their structural integrity). Inspection of technical facilities and installations (e.g., the condition of solar cells in a photovoltaic power station, industrial pipes, wind turbines, broadcast towers, high-voltage or overhead lines) and documentation of their condition. Investigation of inaccessible or not easily accessible areas (e.g., inspections of tanks, flues, shafts, roofs, fire protection systems, and drainage pipes). Measurement of buildings and facilities (e.g., to calculate volume and space). Generation of landscape and location analyses, hydrological modelling and digital elevation modelling. Observation of areas threatened by natural disasters, to provide early warnings and allow safety measures to be implemented. Corporate security duties such as perimeter protection, monitoring of premises, and investigation of alarms. Carrying devices (e.g., infrared cameras to examine electrical systems at altitude, hotspots in photovoltaic power stations, heat bridges, hotspots in heat-conducting or electrical systems, leakages). Monitoring of major incident sites to deploy and coordinate effective support from emergency and security services (especially in confusing situations, inaccessible areas and/or those not yet deemed to be safe). Identification and documentation (video, sound, and photos) of the causes and timelines of losses (e.g., building, fire, environmental or system damage) to preserve evidence.
