O'Mara Constructions has extensive experience designing & building new homes in high bushfire prone area's. Having lived in Hawkesbury all of our lives and with many of our sub-contractors we have experienced many bushfire's and seen the extent of fire on newly constructed homes & existing dwellings.
As per AS3959 which is the Australian Standard for Construction of buildings in bushfire prone areas there are six categories of bushfire attack levels. They are;

BAL simply means "Bushfire attack level"

We also need to consider the materials used, the location of services, access to site, maintenance, just to name a few.We can design & construct a fire bunker. This is NOT design as a safe haven but more as a last option when escape is not possible
We can design & construct a fire sprinkler system with back-up hose reels supplied by a pool/tank/dam to protect the home to suit the site conditions and owner requirements More information can be found at the NSW rural fire service website;www.rfs.nsw.gov.au
