I don’t think that an external fire egress path would necessarily show on a Building Plan …. just as the common property plan does not show fire egress routes through the building. These are generally determined by a Fire Engineer or a Building Surveyor and may be recorded somewhere differently than the Building Plan.
The SC must have a Fire Egress plan or it would not be mentioned in your By-law. Can you ask your SC for a copy of the plan? From my experience in QLD the fire egress routes should be displayed in a prominent place within your building, along with the meeting place for all persons after they have evacuated the building.
I would imagine that any branches on a path would need to be trimmed to the height of approx 2.5 m and to an appropriate width to allow people to escape quickly. The following linked legislation hopefully should provide you some answers.
Strataman says this: “The NSW Environmental Planning & Assessment Regulation 2000 Part 9: Fire Safety… requires that “the owner of a building, to which an essential fire safety measure is applicable, is required to maintain each essential fire safety measure in the building”. Failure to comply with this legislation can lead to significant fines and possibly serious legal ramifications for those responsible.
An appropriately qualified person, such as a Fire Engineer or Building Surveyor, must inspect the fire safety measures and provide an initial Fire Safety Certificate (also commonly called a Fire Safety Installation Certificate) to the Owners Corporation for all new buildings or recently ‘altered’ ones.
This certificate must then be provided to the local council and the Fire Brigade and a copy displayed in a prominent location within the strata building. Then, each year, the whole inspection process happens again and any ‘defects’ are reported to the Owners Corporation so they can be corrected. Once all the issues with compliance are fixed, the Annual Fire Safety Statement is then sent to the local council and the Fire Brigade with a copy displayed in a prominent location within the strata building.”
