Defence sites can be complex when the historical uses of the structures and sites is not fully documented nor known. At D3 we have characterised for decontamination and demolition more than 100 buildings and structures at weapons and defence sites, often starting from scratch since no building data is available.

Developing robust characterisation reports for each structure with identification of hazardous wastes means that occupational health of the decontamination teams is facilitated and the correct waste management procedures are followed.
