Executive Summary
This Tree Assessment Report has been commissioned by Laing O’Rourke to report on trees
within the site of the proposed subdivision development at Olivia Gardens, Surry Hills NSW.
This report has been commissioned to outline the health, condition, stability of these trees as
well as the viability for retention of these trees under the scope of demolition of works. The
scope of this report includes all trees within areas that may be impacted by the proposed
development
All trees within the boundaries of the site (Trees 1-53, 56, 57) have their Tree Protection Zone
(TPZ) totally encroached by the proposed demolition, construction and required earthworks as
defined by AS4970-2009 Protection of Trees on Development Sites. These trees are not be
viable to be retained under the proposed demolition scope of works and therefore they are
recommended for removal.
Trees 54, 55, and 68 are in good health and condition and these trees remain viable to be
retained under the proposed demolition scope of works and are to be protected in accordance
with Section 6.0 below.
Recommendations for tree retention or removal are summarised as follows:

Scope of Works
This Tree Assessment Report has been commissioned by Laing O’Rourke to report
on trees within the site of the proposed development at Olivia Gardens, Surry Hills.
This report has been commissioned to outline the health, condition, stability of these
trees as well as the viability for retention of these trees. The scope of this report
includes all trees within areas that may be impacted by the proposed development.
On 11 December 2014, Glenn Bird of Birds Tree Consultancy attended site and
inspected the subject trees from the ground. There was no aerial inspection carried
out. We undertook a Visual Tree Assessment (VTA) (Mattheck & Breloer, 1994).
Tree heights are measured using a Nikon Forestry 550 Heightmeter.

Impact of Development
4.1
Tree Protection Zones
Tree Protection Zones have been defined for the subject trees in order to define the
encroachment of the proposed development in accordance with AS4970-2009. The
tree protection zones (TPZ) required have been taken as a circular area with a
radius 12 x the diameter at breast height of the tree. This requirement is in line with
Australian Standard AS 4970-2009 Protection of Trees on Development Sites. This
standard defines a maximum of 10% encroachment to be minimal encroachment.
Any encroachment over 10% requires the site arborist to give consideration as to
the viability of the tree due to the proposed development.

Development Impact
The proposed demolition works and light rail construction will impact the entire site
within the boundaries from kerb to kerb. As a consequence, trees 1 to 53 and 56,
57 will be impacted and the Tree Protection Zones entirely encroached by the
proposed development. These trees are not viable as defined by AS4970-2009 to
be retained due to the proposed development. Trees 54 and 55 are on the opposite
side of Parkham Place and are to be retained and protected. Trees 58 to 67 will
have their Tree Protection Zones completely encroached by the proposed
demolition works and therefore these trees will not be viable to be retained under
the proposed development. Trees 58 to 67 are not preserved by City of Sydney Tree
Preservation Order. The grove of Casuarina spp. identified as tree 68 are located in
the adjacent Wimbo Park. These trees will not be impacted by the proposed
demolition works however one tree within this grove requires the pruning of one
primary lateral branch in order to allow clearance for scaffolding. Refer to figure 1

for detail of this branch. All pruning is to be carried out by qualified arborist AQF
Level 3 or greater and in accordance with AS 4373-20007 Pruning of Amenity Trees.
Trees within this grove are to be retained and protected in accordance with Section
6.0.

Recommendations
All trees within the boundaries of the site (Trees 1-53, 56, 57) have their Tree
Protection Zone (TPZ) totally encroached by the proposed demolition, construction
and required earthworks as defined by AS4970-2009 Protection of Trees on
Development Sites. These trees are not be viable to be retained under the proposed
demolition scope of works and therefore they are recommended for removal.
Trees 54, 55, and 68 are in good health and condition and these trees remain viable
to be retained under the proposed demolition scope of works and are to be protected
in accordance with Section 6.0 below.
Recommendations for tree retention or removal are summarised as follows:

Pre-Construction Tree Protection Measures
6.1
General
All tree protection works shall be carried out for trees to be retained before
excavation, grading and site works commence. Tree protection works shall be
inspected and approved by a Consulting Arborist meeting AQF Level 5 prior to
construction works commencing.
All trees to be retained are outside of the site boundaries. The site is proposed to
be completely fenced off and this site fencing is to be adequate with regards Tree
Protective Fencing as outlined in 6.3 below. Should any changes to the site fencing
or hoarding be proposed, Tree Protective Fencing is to be installed as per 6.3 below.
Storage of materials, mixing of materials, vehicle parking, disposal of liquids,
machinery repairs and refueling, site office and sheds, and the lighting of fires,
stockpiling of soil, rubble or any debris shall not be carried out within the tree
protection zone of existing trees to be retained. No backfilling shall occur within the
tree protection zone of existing trees to be retained. Trees shall not be removed or
lopped unless specific instruction is given in writing by the Superintendent.
6.2
Identification
All trees to be protected shall be clearly identified and all tree protection zones
surveyed.
6.3
Protective Fence
Fencing is to be erected around existing trees to be retained. Protective fencing is
to be installed to the full extent of the tree protection zones within the site. This
fencing is to be erected prior to any materials being brought on site or before any
site, civil works or construction works commence. The fence shall enclose a
sufficient area so as to prevent damage to the Tree Protection Zone (TPZ) as
defined in 4.1 above. Fence to comprise 1800mm high chain wire mesh fixed to
50mm dia. Galvanised steel posts. Panels should be securely fixed top and bottom
to avoid separation. No storage of building materials, tools, paint, fuel or
contaminants and the like shall occur within the fenced area.
6.4
Mulching
Install mulch to the extent of all tree protection fencing. Use a leaf mulch conforming
to AS 4454 which is free of deleterious and extraneous matter such as soil, weeds,
sticks and stones and consisting of a minimum of 90% recycled content compliant
with AS 4454 (1999) and AS 4419 (1998). All trees marked as to be removed on the
proposed development are to be chipped and reused for this purpose. Place mulch
evenly and to a depth of 100mm.

Site Management Issues
7.1
Soil Compaction
Plant and pedestrian traffic during the construction period will cause significant soil
compaction. This will be exacerbated by increased water expected on these soils
as result of adjacent construction and weather. Compaction of the soil within the
Tree Protection Zone will reduce the voids between soil peds or particles therefore

will reduce the gaseous exchange capacity of the root system which will slow critical
metabolic processes such as respiration which produces Adenosine Triphosphate
(ATP) which provides energy for the photosynthesis, which in turn provides
photosynthates such as glucose. These photosynthates provide the carbohydrates
required for tree extension growth, girth expansion, reproduction and pest and
disease resistance. No pedestrian or plant access is permissible to the TPZ of trees
to be retained.
7.2
Site Access
Sufficient access is required to enable efficient construction. It is essential to
delineate access zones or corridors which will provide suitable access without
damaging the existing trees to be retained or causing compaction to the root zone.
7.3
Excavation within Tree Protection Area
No excavation is to be carried out within the tree protection zones of retained trees
without the permission and supervision of the site arborist (AQF5)
7.4
Possible Contamination / Storage of Materials
The construction site will require the use of many chemicals and materials that are
possible contaminants which if not managed will pose a risk to the existing trees.
These possible contaminants include fuels, herbicides, solvents and the like. A site
specific Environmental Management Plan has been provided and this specific risk
identified and addressed.
8.0
Tree Protection Measures During Construction
8.1
Maintenance of Pre-Construction Tree Protection Measures
The Pre-Construction Tree Protection Measures identified in 6.0 above are to be
maintained in good and serviceable condition throughout the construction period.
8.2
Possible Contaminants
Do not store or otherwise place bulk materials and harmful materials under or near
trees. Do not place spoil from excavations within the tree protection zones. Prevent
wind-blown materials such as cement from harming trees. All possible contaminants
are to be stored in a designated and appropriate area with secure chemical spill
measures such as a bund in place.
8.3
Physical Damage
Prevent damage to tree. Do not attach stays, guys and the like to trees. No
personnel, plant, machinery or materials are to be allowed within the tree protection
fencing.
8.4
Compaction
No filling or compaction shall occur over tree roots zones within tree protection
fenced areas. Where construction occurs close to or the Tree Protection Zone of
trees to be retained it shall be necessary to install protection to avoid compaction of
the ground surface. This protection is to be planks supported clear of the ground
fixed to scaffolding.

23
8.5
Trenching
No Trenching should be necessary within the Tree Protection Zones of trees to be
retained or within tree protection fencing.
8.6
Site Sheds / Amenities/ Storage
Site sheds, site amenities, ablutions and site storage shall be in the area clear of all
TPZ of all trees to be retained. Chemicals and potential contaminants are to be
stored appropriately and this storage area is to be enclosed by a chemical spill bund
to prevent the potential run off of contaminants in the event of a spillage or accident.

This Appraisal has been prepared for the exclusive use of the Client and Birds Tree
Consultancy.
Birds Tree Consultancy accepts no responsibility for its use by other persons. The
Client acknowledges that this Appraisal, and any opinions, advice or
recommendations expressed or given in it, are based on the information supplied
by the Client and on the data inspections, measurements and analysis carried out
or obtained Birds Tree Consultancy and referred to in the Appraisal. The Client
should rely on the Appraisal, and on its contents, only to that extent.
Every effort has been made in this report to include, assess and address all defects,
structural weaknesses, instabilities and the like of the subject trees. All inspections
were made from ground level using only visual means and no intrusive or destructive
means of inspection were used. For many structural defects such as decay and
inclusions, internal inspection is required by means of resistograph or similar. No
such investigation has been made in this case. Trees are living organisms and are
subject to failure through a variety of causes not able to be identified by means of
this inspection and report.
