Use of cracking of building elements as an indicator of structural performance can be problematic. Where cracking is present in a building element the inspector has to be alert to the possibility that the cracking may be the result of one or more of a range of factors and that the significance of the cracking may vary see paragraph E2. Cracking in a building element may constitute a defect in a variety of ways.

In many cases a particular cracking occurrence may result in more than one type of defect, a serviceability defect and an appearance defect. The inspector should determine whether the cracking constitutes a major or minor defect, based on the expected impact of the cracking. Cracking of a building element is an appearance defect where in the opinion of the inspector the only present or expected consequence of the cracking is that the appearance of the element is blemished.

Cracking of a building element is a serviceability defect where the opinion of the inspector the present or expected consequence of the cracking is that the function of the building element is impaired. Cracking of a building element is a structural defect where in the opinion of the inspector the present or expected consequence of the cracking is that the structural performance of the building element is impaired, or where the cracking is the result of the structural behaviour of the building.

The criteria for determining whether cracking is a structural defect are not solely related to crack width. Cracking in a structural element does not necessarily indicate a structural defect.

Cracks can be repaired and ax a small amount of wall will need to be replaced. Door and windows stick service pipes can fracture. Extensive repair work qs breaking out and replacing sections of walls, especially over doors and windows. Walls lean or bulge noticeably, some loss of bearing in beams. Table F1 provides information on defects subsets and some examples of each type of defect.

Integrity of the element compromised to the extent that collapse has occurred or is imminent.

Damage to the extent that the element is unserviceable or may become so soon. Circumstances where the consequential damage is out of proportion to the initial factor. Cracked power point in a wet area. Brick wall damaged to the extent that stability is impeded. Damaged support to a ceiling such that collapse is possible. Distortion to the extent that the element is unserviceable or may become so soon. 4439.1 ability of the property to resist weather has been compromised eg.

Sagging roof to the extent that allows ingress of vermin or rain. Distortion reduces support for structural members.

Cavity wall has distorted due to the failure of ties; retaining wall rotated. Deflection of a lintel to such an extent that joinery is jammed; footings sunk. Deflection of elements consistent with significant settlement of footings.

Water penetration to the extent that the element is unserviceable or may become so soon. Moisture present to the extent that conditions are conducive to structural deterioration or unhealthy environment. Leaking roof flashings causing water penetration into the building.

Slab edge dampness; rising damp causing salt attack. Material deterioration to the extent that the element is unserviceable or may become so soon. Material deterioration to the extent that conditions are conducive to structural deterioration or unhealthy environment. Rusting of structural connections and members such that the strength of the member has been reduced.

Severe delignification such that the strength of the member has ws reduced. Decay in timber members.
