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"
Flame zone is the highest level of attack and is usually when a site backs directly onto this bush, surrounded by bushland or at the top of a steep embankment. The BAL rating can be classified by self assessment or by a fire consultant but needs to be approved by council after consultation with the RFS (Rural Fire Service)
The categories of attack are determined by:
Homes that are designed in bushfire prone area's need special consideration in design of certain construction elements. The main considerations are for the following items;
| || |
There are numerous "passive" controls methods of protecting the home from bushfire. Each project needs to be evaluated on a case by case basis but can include any or a combination of the following items to provide protection;
| || |
Other considerations need to be made for specific "active" control methods, such as;
| || |
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
We have current designs of homes that although can't guarantee complete bushfire protection they can at least be adapted to minimise all possible risks and increase the safety of the owner and their possessions to suit the conditions on site. All our design will need to be viewed and approved by the RFS priory to any approval be ing granted by council or any work commencing on-site
