This article is the first of several articles that explore the TREC definition of performance as applied to slab-on-ground foundations. It is not possible for a TREC inspector to stay in compliance with the SOP if they do not understand this issue. Real estate agents are going to have a hard time understanding inspection reports if they do not understand how the TREC definition of performance applies to slab-on-ground foundations. This article and the other associated articles explore the issue of slab-on-ground foundation performance in detail.
Old and new definitions of performance in the SOP
To get started, consider the definition of performance used in previous editions of the SOP:
The act of carrying out, completing, executing or achievement of an operation, design or function consistent with the intent of the manufacturer, designer or accepted industry practice.
Here is the current definition:
Achievement of an operation, function or configuration relative to accepted industry practices with consideration of age and normal wear and tear from ordinary use.
Note that in the older version, the intent of the manufacturer, designer or accepted industry practice was the key to determining proper performance. In the current version, there is no mention of intent. Bear in mind that intent is always the intent of a person or group of people. Getting rid of intent, at least on the surface, makes the definition sound less subjective.
In place of intent, TREC inspectors are now directed to look at accepted industry practices with consideration of age and normal wear and tear from ordinary use.
The next several associated pages are dedicated exploring in greater detail the meaning of performance as applied to slab-on-ground foundations: specifically the concepts of accepted industry practices and consideration of normal wear and tear.
