SCOPE

• This report is a paper based audit tool for the Building Inspector/Compliance Auditor to familiarise themselves with Class 2 to 9 Building Applications prior to undertaking a formal site inspection. Issues of non-compliance or potential breaches of the Building Act 2004 may be identified and then confirmed in a formal site inspection or prior to with the Principal Certifier.

PURPOSE

• This report is intended as an initial paper based assessment of the proposed building work to be undertaken involving Class 2 to 9 building against Act's, regulations, the BCA and Australian Standards. Information gathered in this report may be used as information or evidence to achieve compliant building work through education and/or compliance action.

OBJECTIVE

• To assess initial compliance of broad building and planning requirements for Class 2 to 9 building against the submitted plans for building approval.
  To undertake familiarity of the building plans, project scope of works and site requirements particular to the Class of building and construction prior to site attendance.
  To identify potential areas of conflict with the Building Act 2004 and Standards prior to site attendance.
  To open communication with the Certifier to identify/resolve or explain issues

METHODOLGY

• Inspectors will use the data collected from the 'Class 2 to 9 - Recky - Construction Team Audit Report' to commence the paper audit. This is a desk audit and no field work is required at this stage until the site inspection to complete the audit. Data bases, site plans, elevations etc will be used to complete this audit against the Act, Regulations, BCA and Australian Standards.

  (i)
  it is situated at the top of the building and contains only heating, ventilating or lift equipment, water tanks, or similar service units or equipment; or
  (ii)
  it is situated partly below the finished ground and the underside of the ceiling is not more than 1 m above the average finished level of the ground at the external wall, or if the external wall is more than 12 m long, the average for the 12 m part where the ground is lowest.
  (c)
  In a Class 7 or 8 building, a storey that has an average internal height of more than 6 m is counted as—
  (i)
  one storey if it is the only storey above the ground; or
  (ii)
  2 storeys in any other case.
  (d)
  For the purposes of calculating the rise in storeys of a building—
  (i)
  a mezzanine is regarded as a storey in that part of the building in which it is situated if its floor area is more than 200 m2 or more than 1/3 of the floor area of the room, whichever is the lesser; and
  (ii)
  two or more mezzanines are regarded as a storey in that part of the building in which they are situated if they are at or near the same level and have an aggregate
  2
  floor area more than 200 more than 1/3 of the floor area of the room, whichever is the lesser.

  SPECIFICATION A2.3
  
  FIRE-RESISTANCE OF BUILDING ELEMENTS
  
  1. Scope
  This Specification sets out the procedures for determining the FRL of building elements.
  2. Rating
  A building element meets the requirements of this Specification if—
  (a) it is listed in, and complies with Table 1 of this Specification; or
  (b) it is identical with a prototype that has been submitted to the Standard Fire Test, or an equivalent or more severe test, and the FRL achieved by the prototype without the assistance of an active fire suppression system is confirmed in a report from a Registered Testing Authority which—
  (i) describes the method and conditions of the test and the form of construction of the tested prototype in full; and
  (ii) certifies that the application of restraint to the prototype complied with the Standard Fire Test; or
  (c) it differs in only a minor degree from a prototype tested under (b) and the FRL attributed to the building element is confirmed in a report from a Registered Testing Authority which—
  (i) certifies that the building element is capable of achieving the FRL despite the minor departures from the tested prototype; and
  (ii) describes the materials, construction and conditions of restraint which are necessary to achieve the FRL; or
  (d) it is designed to achieve the FRL in accordance with—
  (i) AS 2327.1, AS 4100 and AISC Guidelines for Assessment of Fire Resistance of Structural Steel Members if it is a steel or composite structure; or
  (ii) AS 3600 if it is a concrete structure; or
  (iii) AS 1720.4 if it is a timber element other than fire-protected timber; or
  (iv) AS 3700 if it is a masonry structure; or
  (e) the FRL is determined by calculation based on the performance of a prototype in the Standard Fire Test and confirmed in a report in accordance with Clause 3; or
  (f) for fire-protected timber, it complies with Specification A1.1 where applicable.
  
  3. FRLs determined by calculation
  If the FRL of a building element is determined by calculation based on a tested prototype—
  (a) the building element may vary from the prototype in relation to—
  (i) length and height if it is a wall; and
  (ii) height if it is a column; and
  (iii) span if it is a floor, roof or beam; and
  (iv) conditions of support; and
  (v) to a minor degree, cross-section and components; and
  (b) the report must demonstrate by calculation that the building element would achieve the FRL if it is subjected to the regime of the Standard Fire Test in relation to—
  (i) structural adequacy (including deflection); and
  (ii) integrity; and
  (iii) insulation; and
  (c) the calculations must take into account—
  (i) the temperature reached by the components of the prototype and their effects on strength and modulus of elasticity; and
  (ii) appropriate features of the building element such as support, restraint, cross-sectional shape, length, height, span, slenderness ratio, reinforcement, ratio of surface area to mass per unit length, and fire protection; and
  (iii) features of the prototype that influenced its performance in the Standard Fire Test although these features may not have been taken into account in the design for dead and live load; and
  (iv) features of the conditions of test, the manner of support and the position of the prototype during the test, that might not be reproduced in the building element if it is exposed to fire; and
  (v) the design load of the building element in comparison with the tested prototype.
  
  4. Interchangeable materials
  (a) Concrete and plaster — An FRL achieved with any material of Group A, B, C, D or E as an
  ingredient in concrete or plaster, applies equally when any other material of the same group is
  used in the same proportions:
  
  Group A: Any portland cement.
  Group B: Any lime.
  Group C: Any dense sand.
  Group D: Any dense calcareous aggregate, including any limestone or any calcareous gravel. Group E: Any dense siliceous aggregate, including any basalt, diorite, dolerite, granite, granodiorite or trachyte.
  
  (b) Perlite and vermiculite — An FRL achieved with either gypsum-perlite plaste or gypsum vermiculite plaster applies equally for each plaster.
  5. Columns covered with lightweight construction
  If the fire-resisting covering of a steel column is lightweight construction, the construction must comply with C1.8 and C3.17.
  
  6. Non-loadbearing elements
  If a non-loadbearing element is able to be used for a purpose where the Deemed-to-Satisfy Provisions prescribe an FRL for structural adequacy, integrity and insulation, that nonloadbearing element need not comply with the structural adequacy criteria.
