Audits for hazardous materials (i.e. asbestos) may need to be completed on some older buildings or potentially contaminated sites (eg petrol stations with underground tanks). The recommendation and implications of these audits can be expensive.
Asbestos, for example, may need to be removed (and replaced with something more suitable) not only in the area of your building works, but in adjacent areas. Once you start removing it, where do you stop…?
Other hazardous materials may include:
- Lead paint – to be removed,
- Contaminated soil,
- Petrol tanks,
- Bird poo (faeces) … Yes, it is possible in the roof space of a very old building that the unchecked buildup of this can become excessive, and a hazard that needs removing.
