The document provides an outline for a presentation on building condition surveys. Some key points: 1) The presentation will cover survey and defect identification, examples of common building defects, inspection procedures, reporting methods, and analysis of inspection results including overall building ratings and predictive models. 2) Building defects are defined as areas of non-compliance to regulations or standards, or conditions outside of acceptable norms. Common defects discussed include cracks, foundation issues, and water damage. 3) Inspection procedures involve both visual and technical examinations. Reporting standards vary but typically involve documentation of defects, condition assessments, and recommendations for improvements. 4) Analysis of results includes categorizing defects, calculating overall building ratings, examining defect distributions

3. Survey & Defect
Survey (Hollis & Gibson – Surveying
Buildings, 2005):
Inspection & investigation of construction &
services of property in sufficient details to enable
surveyor to advise what impact the condition &
circumstances of that property will have upon client.
Defects:
areas of non-compliance to the bye-law, regulation, http://myprservices.com
standard (mostly not subjective)
Out of acceptable condition (subjective)

“Defects will occur in buildings. It is one of the great certainties in
construction, the equivalent of death and taxes in life more generally”.

It wasn’t hit by the massive earthquake. In true fashion of the Ripley Legacy, it
was built to reflect the odd 1812 earthquake that measured 8.0 on the rick.
The building has now become one of the most photographed in the world.

31. SUMMARY
 Start up: building defects identification – more than an “album”
 Reporting: standard and certified – qualify to stand in court
 Next level: building defect analysis – defects are here & there:
so what?
 Next level: performance measurement – information for future
design
 Next level: building defect “advantage”? – new theory around
the corner
“We do not want a structural survey. If you can just have a quick
look at the house to make sure that it is structurally sound, that
will be fine”
