Survey & Defect

UKM:Che-Ani 2012

http://myprservices.com

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

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.

http://www.buildingdefects.com.au/

http://www.blaketurner.com

Defects:areas of non-compliance to the bye-law, regulation,

standard (mostly not subjective)Out of acceptable condition (subjective)

Survey & Defect

UKM:Che-Ani 2012

BUILDING DEFECTS – An Example

Growth of mould and algae due to water ponding and continuous

dampness Water ponding due to blockage of outlet to rainwater downpipe (due to small outlet) – it’s very

hot during the course of inspection

BUILDING DEFECTS – An Example

Water mark on the ceiling surface due to water penetration

from leaking roof (the brown color suggest it dripped via timber trusses, perhaps the

trusses need structural inspection)

Stalactite effect due to water proofing failure at

upstairs toilet

UKM:Che-Ani 2012

An apparent defect has been perceived when

It looks wrong Something

smells strange

Someone heard

something

It just felt wrong

Something felt

BUILDING DEFECT ACTION FLOW (WOOD, 2009 – BUILDING MAINTENANCE)

Inspect All seem OK?

Allocate priority in accord with agreed

criteria

Is a matter of health and safety

Record and keep in mind

for future

Defect confirmed

No further action at this

time

UKM:Che-Ani 2012

Initiate urgent action

Check and record work in progress early on and periodically

Commission rectification work

Discuss and agree with client and users

Select appropriate specialists for

further inspection

Prepare or select appropriate rectification specification

NEXT: How “defect” benefit us…

UKM:Che-Ani 2012

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.

SUMMARY

UKM:Che-Ani 2012

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”(Extract from client’s letter of instruction)
