Use if micobiological assessment - expertise in wood-destroying fungi - in determining the soundness of wood structural members.
This article discusses the role of mycology and microbiology in detecting & assessing damage to wood beams, joists, posts, studs, rafters etc. Mycology can provide key information about the conditions that invite wood destroying fungi (molds such as Meruliporia incrassata - the "house eating fungus"), as well as assisting in recognition of mold infection or contamination in structures. Page top photograph: yellow Meruliporia incrassata fungal growth on an indoor wood surface.
This article series describes the various methods used to test & evaluate the structural integrity of wood-framed buildings where focus is on the condition of structural wood posts, beams and other framing members. We discuss the problems surrounding hidden rot or decay, the presence or absence of moisture or other instrument-detectable clues, and the problem of subjective decisions to replace or not-replace suspect wood structural members.

Using microbiological assessment requires an expert, mateiral samples, time, cost. Often we use microbiological assessment as an additional method to aid a visual assessment of rot damage to a structure.
Scope = Microscopic to sample size (minor usage in deciding actual replacement, adds genuine weight to reports). Not in situ assessment
Note: in our opinion, microbiologists and aerobiologists can provide a useful supporting role in assessing building conditions (mold or other IAQ hazards) including providing additional screening for evidence of hidden but active wood destroying fungi.
Few microbiologists nor mycologists have the requisite familiarity with building science and construction failures to serve as a primary building screener for hidden damage.
