This Standard provides minimum requirements for non-invasive inspection of buildings for the activity of timber pests and preparation of associated reports. The inspection is to be carried out by a suitably qualified inspector.
This Standard includes limited requirements for invasive inspection.
AS 4349.0 sets out the requirements for building inspections other than those detailed in other Parts of AS 4349.
NOTE: State or Territory legislation may include requirements beyond this Standard.
The basis of this Standard is a non-invasive inspection comprising visual inspection supplemented by non-marking sounding of elements and assessment of moisture content of materials. The Inspector might decide to supplement this type of inspection with other nondestructive techniques or equipment, depending on the particular circumstances; however the use of such further equipment is beyond the minimum requirements of this Standard.
The nature of timber pest activity and non-invasive inspection is such that some residual damage is inevitable in some cases.
For the purposes of this Standard timber pests that damage timber are subterranean and damp-wood termites, borers of seasoned timber and wood decay fungi. This Standard does not require inspection and report on drywood termites or mould.
1 Drywood termites are not included in the Standard inspection and report due to the extreme difficulty in locating the small colonies and the very rare incidence in Australia.
2 Chemical delignification is not a timber pest under the scope of this Standard, even though delignified timber closely resembles timber that has been decayed by a white stringy rot fungus.
Underground inspection is beyond the scope of this Standard. For example, house stumps below ground level, tree roots and the parts of fence posts below ground level are excluded from this Standard.
The purpose of a timber pest inspection on a property is to assess the following:
(a) Evidence of timber pests.
(b) Existence of visually observable damage caused by timber pests.
(c) Susceptibility of building to timber pests.
(d) Further investigations required.
NOTE: Regular, competent inspections are strongly recommended, at least on an annual basis. Where justified, more frequent inspections may be recommended, e.g. in situations considered more conducive to timber pests.
