EXECUTIVE SUMMARY
This report has assessed the Elephants Foot Compactors garbage linen chutes under the provisions of the
1
Building Code of Australia 2010 (BCA) , where it has been determined that the proposed design of the Elephants
Foot Garbage chute constructed from Alkatuff LL711UV linear low density polyethylene plastic complies to the
deemed-to-satisfy (DTS) provisions of the BCA. A summary is detailed in the following table.
BCA PROVISIONS FOR ELEPHANTS FOOT GARBAGE/LINEN CHUTE

BCA Requirements
Outcome
1.
SPRINKLER PROVISIONS
Pass
The chute design must have provisions for sprinkler protection at every second
hopper door on a level by level basis in addition to a sprinkler at the head of the
2
chute in accordance with AS2118.1-1999 .

sprinkler provision at
the head of the chute.
Automatic fire sprinkler systems provide a building with a high level of
protection for both the occupants and environment against a major structural
fire. Sprinklers also protect against major structural damage to a building and
make a return to normal operations following a fire possible.

INTRODUCTION
AE&D has been commissioned by Elephants Foot Waste Compactors to determine if a proposed plastic
garbage/linen chute complies with the provisions of the BCA. Additionally, the ventilation requirements of the
garbage/linen room will be assessed and outlined in accordance with the BCA and relevant Australian Standards.
It is the intention of Elephants Foot Garbage Compactors Pty Ltd to install these chute systems in sprinkler
protected high rise buildings in compliance with the guidelines set out in the BCA.
1.1

BCA ASSESSMENT DATA
This section details the relevant BCA assessment data to the proposal under the current Building Code of
Australia.
CSIRO have been commissioned by Elephants Foot Garbage Compactors to perform the fire hazard property
tests on the chute material and the fire resistance tests on the hopper doorsets. The chute design assessment is
based on these test results. The CSIRO reports are reproduced in Appendix A- Fire Hazard Properties of Chute
Material and Appendix B- Fire Resistance of Hopper Doorsets of this report.
2.1
Chute Design Assessment
Elephants Foot Garbage Compactors have developed a garbage/linen chute constructed of Alkatuff LL711UV
linear low density black polyethylene plastic having a nominal thickness of 5mm and a nominal total mass of 938
3
kg/m . The specific BCA requirements of the chute design are detailed in section 1.2 of this report. The
schematics of the chute system are represented below.
According to the BCA clause E1.5, a high rise building with an effective height of more than 25m requires
sprinkler protection and would need to be Type A construction. The provision of sprinklers is based on AS2118.11999, where in high rise buildings sprinklers must be protected internally at every second hopper door on a floor
by floor basis in addition to a sprinkler at the head of the chute. The proposed chute design complies with these
requirements.
The fire resistance of the self closing hopper doors in the proposed design were tested by the CSIRO resulting in
a FRL of at least -/120/30 (see Appendix A), which complies with BCA Clause C3.13(b). The hopper doors are
constructed from 30mm thick MAXI-LITE panel faced on both sides by 1.6mm thick panels of 250 grade mild steel
sheet. Therefore the hopper door complies with BCA Clause C3.13(d) for openings in shafts.
The chute system has been subjected to the fire hazard property tests in accordance with BCA clause C1.10 and
4
Specification C1.10, which requires tests to be carried out in accordance with AS1530.3-1999 (see Appendix B).
It was determined from this assessment that the chute material had a spread of flame index of 7 and a smoke
developed index of 5, in compliance with BCA C1.10 and Specification C1.10.
The chute must be located within a shaft that complies with the BCA requirements for fire resistance as defined in
Clause C1.1 and Specification C1.1.

2.2
Garbage room Ventilation
The proposed chute is to dispense into an associated garbage room and according to the BCA Clause F4.5, any
room occupied by any person must have either natural ventilation or a mechanical ventilation system complying
with AS1668.2-1991 (see table in Appendix C). While the garbage room is not frequently occupied, ventilation
must be provided in accordance with the requirements of the BCA and will also act to remove odours from the
2
garbage area. The requirements for ventilation in a garbage room is a flow rate of 5 L/s per m of floor area.
If the chute is to be used as a linen chute that dispenses into a laundry then the ventilation required would be 15
2
L/s per m of floor area in a commercial or hospital laundry or 20 L/s for a residential building.
For this particular chute system the following recommendations are proposed to ensure adequate ventilation:
2
•
Garbage rooms must be ventilated to produce a minimum of 5 L/s per m , where it is also recommended
that additional 5L/s per level in the building be provided to ensure adequate ventilation. i.e.
2
Recommended ventilation = 5 L/s per m of garbage room floor area + (5L/s x Number of levels in
building).
•
Laundry rooms in commercial or hospital buildings must be ventilated to produce a minimum of 15L/s per
2
m of laundry floor area. Laundry rooms in a residential building must be ventilated to produce a
minimum of 20L/s per laundry room.
•
Suitable provisions for make-up air paths would need to be provided into the garbage/laundry rooms.

BCA COMPLIANCE ASSESSMENT & RECOMMENDATIONS
The following table identifies the requirements of the Building Code of Australia for the proposed garbage/linen
chute design.
#
BCA Requirements
Outcome
1.
Pass
The chute design must have provisions for sprinkler protection at every second
hopper door on a level by level basis in addition to a sprinkler at the head of the
5
chute in accordance with AS2118.1-1999 .
Pending provisions
have been made for
nd
sprinklers at every 2
level on a floor by floor
basis, in addition to a
sprinkler provision at
the head of the chute.
Automatic fire sprinkler systems provide a building with a high level of
protection for both the occupants and environment against a major structural
fire. Sprinklers also protect against major structural damage to a building and
make a return to normal operations following a fire possible.

CONCLUSION
This report has assessed the compliance of the Elephants Foot Garbage/linen chute design with the BCA’s
regulatory requirements and it has been determined that the design is considered to be at a sufficient level to
demonstrate compliance with the BCA Deemed-To-Satisfy provisions, and thus certification confirming that the
design documentation complies will be issued by AE&D. Provided that the Alkatuff LL711UV linear low density
polyethylene chute being contained in a suitably fire rated shaft, is fitted with hopper doors that have a minimum
FRL of -/120/30 and sprinkler protection is provided in accordance with Clause E1.5 in the BCA and AS2118.11999 when necessary. Provisions must be made for adequate ventilation of the garbage/linen rooms where the
chute dispenses as is detailed in section 2.2 of this report.
