The seemingly obvious but often neglected first stage for all of the survey types listed below is to establish a detailed chronology of prior events (as far back as possible). It is often the case that an event, considered insignificant and consequently unreported by the occupier, holds the key to a particular building problem.
The survey types shown below are not exhaustive, as building problems are nearly always multi faceted, almost always requiring unique approaches. The principal concern of most survey types is the nature of water, in all its forms, and how it has affected the building fabric. Although this implies narrow fields of investigation, it is actually very broad, covering almost all forms of building deterioration with the exception of subsidence or an ‘Act of God’ (although water is often a contributory factor in both of these!).
The survey types shown below are usually interdependent when making a holistic assessment of the entire building envelope. However they can be carried out separately and focused on specific areas if required.
