It is predicated on low threat vegetation and non vegetated areas. However... The Victorian Building Regulations (Items 157 & 158) state that a Class 1, 2, 3, 4, 9a, 9b or 10a building in a Bushfire Prone Area (BPA) must be built to a minimum of BAL 12.5. Refer to Section 5 - Construction Requirements for BAL 12.5. A dwelling is a Class 1a building, and a shed, garage or carport is a Class 10a building.

In Victoria, the Bushfire Management Overlay (BMO) identify properties at extreme risk of bushfire | Bushfire Design Consultants provide bushfire assessments & reports in Victoria BMO WHAT IS A Bushfire Management Overlay The Bushfire Management Overlay (BMO) applies to land that may be significantly affected by extreme bushfires. Whilst development in a Bushfire Prone Area (BPA) may only require a BAL assessment, developments in a BMO may require planning approval by complying with four bushfire protection measures: Defendable Space (vegetation management), Bushfire Construction (BAL), Static Water Supply (water tank), and Access (driveway construction). If you are planning to build, renovate or extend in a BMO, you may need a BMO Report , contact us today to discuss your project and get a quote.

BAL FZ Sections 3 & 9 Direct exposure to flames, radiant heat and embers from the fire front. Section 8 - AS 3959:2018 BAL 40 Reference Guide Refer to Sections 3 & 8 for all BAL 40 Requirements This reference guide is not an exhaustive list of all of the requirements of AS3959:2018, and should be read in conjunction with Australian Standards AS3959:2018 (including Amendments 1 & 2 ), AS1530.8.1, AS1530.8.2 and official test reports and assessments. BAL 40 General (Clause 8.1) A building assessed as being BAL 40 shall conform with Section 3 (General Construction Requirements) and Clauses 8.2 to 8.8 of AS3959:2018. Any element of construction or system that satisfies the test criteria of AS1530.8.1 may be used in lieu of the applicable requirements contained within Clauses 8.2 to 8.8 (see Clause 3.8). BAL 40 Subfloor Supports (Clause 8.2) - Unenclosed Subfloors. Supports (stumps, etc.) shall be (a) non-combustible, or (b) a system conforming with AS1530.8.1. - Enclosed Subfloors. No requirements if the subfloor is enclosed with a cladding that conforms with the wall requirements (sarking not required behind subfloor cladding). BAL 40 Floors (Clause 8.3) - Unenclosed Subfloors. Bearers and joists shall be (a) non-combustible, or (b) have the underside of the combustible elements of the floor system protected with non-combustible material (eg, cement sheet or metal sheet), or (c) a system conforming with AS1530.8.1. - Enclosed Subfloors. No requirements if the subfloor is enclosed with a cladding that conforms with the wall requirements (sarking is not required behind the subfloor cladding). BAL 40 Walls (Clause 8.4) Walls shall be (a) non-combustible (including brick, concrete, rammed earth and mud brick, etc. at min. thickness of 90mm), or (b) cladding on sarked walls that is (i) non-combustible, or (ii) min 9mm thick cement sheet, or (iii) steel, or (c) a system conforming with AS1530.8.1. Any gaps greater than 2mm to be screened with 2mm mesh in corrosive resistant steel, bronze or aluminium. BAL 40 Windows, Sidelights & Doors (Clause 8.5) This section of AS3959:2018 includes multiple compliance paths and detailed variations. Always confirm exact requirements using the current version of AS3959. * Compliance options for BAL 40 windows and doors. (a) A system tested to conform with AS1530.8.1, or (b) Be completely protected by a bushfire shutter, or (c) Follow the 'Deemed To Satisfy' (DTS) provisions of AS3959:2018. (a) System Tested to AS1530.8.1. Window and door manufactures can have their products tested to comply with a BAL rating. Refer to window and door manufacturers for options. Note: Non-combustible frames are usually the only option for BAL 40, however tested timber windows and doors are available from Paarhammer. (b) Bushfire Shutters. Bushfire shutters can be used to protect windows and doors that are not: (a) tested to AS1530.8.1, or (b) do not meet the DTS requirements. Where fitted, they must conform with Clause 3.7 and be made from non-combustible material. (c) Deemed To Satisfy (DTS). - DTS Frames. Window and door frames shall be metal (inc. aluminium). - DTS Glazing. For windows, sidelights and doors, toughened glass with a min. thickness of 6mm. - DTS external glass protection information. All DTS glazing is to be protected by externally fitted screens (glazing protection screens) made from (a) metal, or (b) a tested system to AS1530.8.1, and have 2mm mesh or perforated sheet in (a) corrosive resistant steel, or (b) bronze (no aluminium allowed). For the DTS window option, screens (glazing protection screens) must cover the glazing, and must prevent embers from entering an open window, the use of two screens may be needed in certain cases (see insect/ember screen info below). For the DTS door option, screens (glazing protection screens) must protect the glazing by either screen doors or screens fixed to the face of the openable door to protect glazing (seperate insect/ember screen doors are not a requirement). * Understanding the term 'Screens' in AS3959:2018. The term, 'screen' in this section is used to describe three different applications: 1. Complete Screening . Screens need to be applied externally to cover the entire window or door assembly, including the frame, glazing, sash, sill and hardware. This gives maximum protection from embers and radiant heat. 2. Glazing Protection Screens . Only the glass area is protected by screens. These are fitted externally and reduce radiant heat exposure to glazing. T his could be done by fixing the screening to the window and/or door frame, or using an external insect/ ember screen door. 3. Insect/Ember Screens . These are required on openable windows and may be fitted internally or externally to prevent ember entry when the windows are open. These are required for openable windows at all Bushfire Attack Levels. Doors do not require these, but if fitted externally, need to comply with the screening material for each Bushfire Attack Level. * BAL 40 Screening Material. All screens must be made from mesh or perforated sheet (max. 2mm aperture) using: (a) corrosive resistant steel, or (b) bronze. ( aluminium is not allowed) Refer to AS3959:2018 for frame requirements.
