5 BUILDING CODE OF AUSTRALIA ASSESSMENT

Reference is made to our high-level assessment of the Development Application architectural plans for the

proposed development against the Deemed-to-Satisfy Provisions of the BCA2019.

5.1. Section C – Fire Resistance

The building is required to maintain the fire-resistance levels for Type A Construction (see Part 2.4 of

Report) and will be required to be constructed in accordance with Table 3 of Specification C1.1 of the

BCA.

The external walls must be of non-combustible construction in accordance with BCA Clause C1.9.

5.2. Section D – Occupant Access and Egress

The assumed exits from each tenancy is via:

The western elevation doorway from each Retail Tenancy;

The eastern elevation double doorways from each Retail Tenancy; and

Additional exit doorway(s) located approximately midway along the northern and southern

elevations of the building are required to be provided.

The above exits are considered to provide appropriate travel distances to exits based on an empty floor

plate with two tenancies. Any internal fit-out of the building will have to re-consider the egress travel

distances. Further doors provided to the northern and southern elevations will provide greater flexibility in

the fit-outs with regard to the 20m/ 40m/ 60m travel distance requirements of BCA Clause D1.4 and D1.5.

The exit travel distances will be required to be reviewed as part of the tenancy fitouts.

5.3. Section E – Services and Equipment

Refer to Part 3 ‘Essential Fire Safety Measures’ of the report for the required essential fire safety

measures. This table may be required to be updated as the design develops and options for compliance

are confirmed.

It is noted that BCA Table E2.2b requires a building where the floor area of a Class 6 part of a fire

compartment is more than 2000 m2 must be provided with-

(i) An automatic smoke exhaust system complying with specification E2.2b; or

(ii) Automatic smoke-and-heat vents complying with Specification E2.2c, if the building is single

store, or

(iii) If the floor area of the fire compartment is not more than 3,500 m2 and the building –

(A) Is single storey, an automatic smoke detection and alarm system complying with

Specification E2.2a; or

(B) Has a rise in storeys of not more than 2, a sprinklers system (other than a FPAA101D or

FPAA101H system) complying with Specification E1.5.

The provisions above do not apply to a Class 6 sole-occupancy unit that –

(A) Has a floor area of not more than 2000 m2; and

(B) Is a single storey with a main public entrance opening to a road or open space; and

(C) Is separated for other parts of the fire compartment by construction, including openings,

penetrations and junctions with other building elements, that prevents the free passage of

smoke.


Page 14 of 16

5.4. Section F – Health and Amenity

The building does not include details of the sanitary facilities. Sanitary facilities will be required to be

provided as part of the retail tenancy fit-outs as part of a separate application and specific to the building

use.
