FACADE & WINDOW SITE TESTING MONITORING AND SITE SUPERVISION
During the last 20 years HBC has been engaged by facade design companies, window manufacturing companies, main contractors and building surveying companies to assist with field testing of both facades and window systems. The purpose has been to assist with PS4 construction reviews that are called up for with building consents for new building works.
For older buildings that have had a long history of weathertightness problems HBCs forensic testing methods prove to be very effective to find leaks and to identify defects.
Because of HBC’s experience HBC is now engaged with monitoring of the site field testing and or providing site supervision of the site field testing.
HBC’s experience and expertise with facade works has brought many benefits to the testing process. HBC uses certified testing procedures including the AS/NZS standards and AAMA testing standard which is accepted world wide. HBC has in the past provided assistance to the window industry to develop window field testing standards.
Our testing equipment is very useful for forensic testing, if water ingress is observed during testing the leakage paths can be tracked to locate the leak ingress point of entry. If damage has occurred the extent of the damage can be assessed. Once the defect is identified a remedy can be devised. Once the remedial work is completed a re test can be carried out to test the effectiveness of the repairs.
HBC works closely with Facade Engineers ensuring that consistent test procedures and test equipment is used to best replicate what is carried out in a accredited testing facility. Testing is carried out generally in accordance with AS/NZS 4284:2008, NZS 4211 and ASTM E1105 and or to the Facade Engineers specific instructions.
