Step 2: Note the extent of the problem for each case
Appropriate use of structural timber.
Inspectors should consider the following issues:
- Where is the suspect timber located in the building? For example, timber used in structural situations (such as roof trusses or load bearing walls) will need further investigation. However, if the timber is located in a non load-bearing and non-braced wall, then compliance with the Building Code may be achieved with non load-bearing timber.
- How extensively has the suspect timber been used throughout the building? For example, if only two studs have been identified as being potentially non load-bearing, then it may be a simple site instruction to replace the studs. However, if the suspect timber is used extensively throughout the building, then the options listed further in this document should be considered.
- Is the affected member redundant? In many parts of the building there are clusters of timber members located in areas such as wall junctions, columns, and openings in walls. Where a suspected non load-bearing timber member is used and is surrounded by structural timber, then this may easily comply with the Building Code.
Such considerations will help inspectors make a decision about whether the timber needs to be of a particular structural grade, and whether there is an issue to addressed.
