Browse Forums Building Standards; Getting It Right! 1 Nov 04, 2013 8:46 pm Need some sound advice Had an insurance claim which was accepted and repairs undertaken but insurers omitted damage-cracking intentionally off their engineers reports. Long story short 3 yrs later we pulled them up (still not completed original repairs) and claim never seen... Got another engineer who states doesn't meet BCA for sub vents or articulation.... Sub vents are 6000 or 200mm x 15mm x 21 being the minimum and there are No articulation joints as we think the architect intentionally designed as to negate (class m veneer wall 5400mm long with horizontal window 3000mm l by 600mm h, no articulation noted on engineers design or architects designs) Cracking happened as the insurers asked us not to reinstate capping when we were flooded by mains water escaping over several months, 10,000 litres per day...within a week we saw cracking and over 8 months deteriorated and sunk. So, two questions, is sub floor ventilation at 6000 compliant as a minimum and were articulation joints applicable when all the walls are intentionally designed under the maximum lengths of wall and finally, if the articulation guide states required if an opening is over 900mm x 900mm does this mean an opening 600mm x 3000mm is intentionally under 900mm Insurers have obviously denied claim within hrs... Re: Sub floor vents and articulation victoria what is the co 2Nov 05, 2013 8:25 pm For Victoria ( climate zone 3 ) the BCA according to 3.4.1.2 "Sub-floor Ventilation and Clearance" states that you should have 6000sq mm per 1 sqm of wall.
A standard brass vent will let you space these at around every 2000mm of the wall. We used to space our standard brick vents every 1500mm max depending on how the house was designed and frequently used to end up with these spaced at 1000mm to 1200mm. http://www.google.com.au/url?q=http://w ... cI8z1ctrKw http://www.flooringtech.com.au/unit2_in ... culate.htm Articulation joints are supposed to be every 6000mm max but a lot depends on the site classification, house design and the original engineer who should have supplied this info with the construction drawings. What capping are you referring to ? Stewie Re: Sub floor vents and articulation victoria what is the co 3Nov 05, 2013 8:45 pm Hi Steve, thanks for the reply. Sub floor we have on a 5.4 wall 21 vents at 200mm x 15mm brick vents, which we calculated out to 6000. The insurance engineer has stated as there is concrete capping it should have been more than the 6000 minimum? With the articulation I guess we can try the original architect and engineer and building surveyor, but seeing there is a problem we can only hope there was intentional design. The engineer report states because the window is 600mm x 3000mm it exceeds the 900mm x 900mm and therefore there should be articulation as per the building code every 5m as per the BCA.
