The purpose of this report is to identify the extent to which the architectural

design documentation complies with the relevant prescriptive provisions of BCA

2007.

Assessment of the proposed design considers each prescriptive BCA provision,

and identifies such as either:

(a) Being complied with; or

(b) Not being complied with; or

(c) Requiring the provision further detail with the future Building Permit or

other application or

(d) Not being relevant to the particular building works proposal.

With reference to the BCA Assessment Summary contained within Part 3

above, the following detailed analysis and commentary is provided.

This commentary is formulated to enable the design documentation to be further

progressed, for the purpose of evidencing the attainment of compliance with the

relevant provisions of the BCA.

44..22 SSEECCTTIIOONNBBSSTTRRUUCCTTUURREE

Cl. B1.1 The resistance of a building or structure must be greater than the most critical

action effect determined by BCA Clauses B1.2 & AS/NZS 1170.02002, and

B1.4.

Cl. B1.2 The structural design of the building must be determined in accordance with the

Cl. C1.1

contd* Roofs

As the buildings are less than 25m in height and of mixed classification it isrequired to be fire rated to achieve a 60 minute resistance to the incipient spread offire. Please advise if anything other than a concrete roof is proposed as aperformance based solution can be utilised to remove the fire rating where

necessary.

* Lintels

Clause 2.4

Lintels within the external walls of the building are required to have an FRLequivalent to that of the part of the building within which it is located. Note theconcessions in clause 2.3 of Specification C1.1 re concessions for fire ratings

requirements for lintels.

* Fire Rated Wall Construction

Table 3(e)

All walls required to be fire rated must be constructed of non-combustibleconstruction. The same is applicable for the flooring and floor framing of lift pits.

Specification C1.1 Requirements for Type C Construction (class 3

single storey stand alone buildings)

*External Walls

Within 1.5m of a fire source feature

An FRL of not less than 60/60/60.

Note: the fire rated party walls must extend to the underside of the ceiling above ifthat ceiling has a 60 minute rating, or to the underside of the roof covering if it isnon-combustible (and the fire rated walls must not be crossed by timber other thanroof battens 75mm x 50mm maximum).

* Roofs

No fire rating required.



19/38

- 14 -

Cl. C1.8 If lightweight plasterboard is to be used in a fire rated application please providea copy of the manufacturers data sheet detailing the static load and resistanceachieved for the systems proposed within this building.

Cl. C1.10 The fire hazard properties of any materials other than floor, wall and ceilinglinings should accord with the following:

Have a spread of flame index exceeding 9 Have a smoke developed index exceeding 8, if the spread of flame index

exceeds 5

Floor, wall and ceiling linings must have fire hazard properties accordant withBCA Specification C1.10a for a non-sprinkler protected building, whichspecifies that:

Floor Materials.

Must have a critical radiant heat flux for the building not less than 2.2 and amaximum smoke developed rate of 750 % minutes.

Class 3 Wall and ceilings.

For wall and ceiling linings a group number of 1 for fire stairs, 1 and 2 for public

corridors and 1, 2 and 3 for specific area and other areas.

Class 6, 7a and 9b Wall and ceilings.

For the class 6, 7a and 9b parts a group number of 1 for fire stairs, 1 and 2 for

public corridors and 1, 2 and 3 for specific areas and other areas, except theceilings of specific areas which are limited to groups 1 and 2.

Cl. C2.6 We have tried to assess the spandrel separation proposed for the building but due

to the lack of detail on the elevations it is difficult to determine where glazingstops and a spandrel panel starts, e.g. grid 3-4, south elevation, as there may bespandrels panels behind but this part of the elevation appears to be glazing.

As such this issue should be discussed at a design meeting to ensure that thisissue has been considered in respect to the provision of either a 1.1m widehorizontal spandrel that extends a minimum of 450mm past the edge of any

openings or a vertical spandrel not less than 900mm high. Both types ofspandrels are required to be 60 minute fire rated.

We also note from our review of the plans that some of the spandrels do notappear to extend the required 450mm past the end of the openings when ahorizontal spandrel has been used to achieve compliance, e.g. balconies to unit

E2.2, E3.3, F2.2, F2.1.

Cl. C2.7 Where walls are used to fire separate sole-occupancy units from each other orfrom public corridors, they must:

Have an FRL not less than that specified in Clause C1.1 above. Not be crossed by elements other than timber battens of 75x50-mm in size. Extend to the underside of a floor having the same FRL as the wall, or to

the underside of the roof cover.

Cl. C2.8 Classifications located in the same storey (i.e. Ground floor - Class 6 retail, class9b E-learning and Class 3 residential accommodation) must either be separatedusing firewalls as described in Clauses C1.1 and C2.7 above, or the entire floorconstructed to the higher FRL applicable to the classification concerned.

Where separation is not possible the FRL of elements within the ground floorwould need to be increased to a minimum three (3) hour rating.



20/38

- 15 -

Cl. C2.9 As mentioned within Clause C2.8, similarly, if no firewall is provided toseparate classifications, then the floor between the ground floor and Level 1would need an FRL of 180/180/180. Refer to Specification C1.1 above inrelation to the fire rating requirements for floors.

Cl. C2.10 The walls of the lift shaft need have a fire rating as specified in Clause C1.1

above. As mentioned within Clause C2.8 throughout the ground floor where theseparate classifications are not fire isolated the lift shaft need be constructed to

The heating shade multiplier for each glazed element (taken from tableJ2.4(c). This is a calculated as follows:

First calculate G in the table. It is the height that the shading

element is located above the top of the window/door head. P is the length the shade part of the building that extends horizontally

to protect each opening. H is the height of the specified window. ThusP/H plus the orientation of the window (north south east west etc)allows you to calculate the heating shade multiplier by using tableJ2.4(c).

The cooling shading multiplier for each glazed element (taken from table

J2.4(d). This is calculated as follows:

Take figures G and P/H from the above calculations. Then review theorientation within table 2.4(d) to determine the figure for the coolingshading multiplier.

Alternatively the energy constants, heating shading multiplier and cooling

shading multiplier can be calculated by this office to determine if compliance isachieved.

To determine if compliance is achieved the aggregate air-conditioning energyvalue attributable to the glazing must not exceed the allowance obtained by

multiplying the faade area of the orientation by the energy index in tableJ2.4(a). Note that where the air-conditioning energy value of a glazed

element is less than zero the value must be taken as zero.

Alternatively if the above information is not available at this stage of the

development process compliance with this clause of the BCA may be

undertaken at the Construction Certificate stage when all information is

readily available.

Cl. J2.5 Where a non-compliance occurs with respect to clauses J2.3 or J2.4 additionalshading of the openings will be required to be provided to achieve compliance.

The requirement for any additional shading can only be confirmed once thecompliance status of clauses J2.3 and J2.4 are known.
