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
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
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
(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.
