Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 60
Review of Environmental Factors
Early works
Subject to approval of the proposal, Roads and Maritime may undertake an early
package of works comprising the construction of an earth platform to the north of the
existing Mona Vale Road carriageway between Tumburra Street and the location of
the proposed fauna land bridge.
This would comprise:
Site clearance and installation of environmental controls
Relocation/adjustment of high voltage and communications utilities
Placement of fill material in layers
Placement of topsoil and seeding.
Construction of the earth platform would use about 85,000 m3 of material which
would be sourced from the Mona Vale Road East Upgrade Project.
Construction staging
To minimise impacts to traffic and to ensure safety risks to workers are minimised, it
is anticipated that the proposal would be constructed in stages. The preliminary
construction staging strategy comprises four stages as follows:
Stage 1: Between chainages 0–1000, carry out widening on the southern side of
the existing carriageway while keeping the traffic on the existing carriageway;
carry out intersection upgrade work at Kimbriki Road
Stage 2: Construct the new (deviated) section of carriageway from
chainage 1000 to Tumburra Street off line from the existing carriageway
Stage 3: Construct the local access road along Harvey Road including
intersection upgrade work at Powder Works Road. This would provide an
alternative access to the Wirreanda Valley area while Stage 4 is being
constructed
Stage 4: Widening on both sides from Tumburra Street to Powder Works Road.
The scope of works for each stage would be subject to review and potential revision
during detailed design and pre-construction planning.
Work methodology
Construction sequence
The work methodology for the proposal would be refined during the detailed design
phase. Construction activities would be guided by a Construction Environmental
Management Plan (CEMP) to ensure works are located within the specified works
areas and implement all safeguards as described in this REF, and any subsequent
measures included as a result of submissions.
The indicative construction sequence for the proposal is as follows:
Issue community update about upcoming roadworks
Establish environmental exclusion zones including the limits of clearing
Install temporary erosion, sedimentation and drainage controls
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 61
Review of Environmental Factors
Establish site compound and stockpile areas
Establish construction phase traffic control, including temporary traffic signs,
safety barriers, line marking changes and similar
Remove property fences and erect temporary security fence as required
Mark trees requiring removal and carry out inspection by suitably qualified
ecologists
Clearing of vegetation
Stripping and stockpiling of topsoil by grader, excavators and trucks
Progressive relocation, adjustment and/or protection of all affected utilities,
services and signage to suit construction staging requirements.
Bulk earthworks (cut/fill operation) by grader, excavator, haul trucks
Drainage works by excavator and haul trucks
Stabilise exposed areas
Recycle suitable excavated material and incorporate unsuitable material in
earthworks within the road reserve where possible
Install Select Material Zone (SMZ) using grader, excavator, haul trucks and roller
compactors
Sprayed seal on top of SMZ
Place lean mix or asphalt sub base using paver and truck
Sprayed seal on top of lean mix concrete paving
Construct retaining walls and other structures
Prepare existing pavement for new lane surfaces using grading and milling
machine
Form new kerbs, gutters, medians and other structures using kerb machine,
concrete truck and hand tools
Construct asphaltic concrete pavement and associated works using paver and
roller
Construct footpath paving using concrete trucks and hand tools
Install temporary pavement as needed to tie-in to existing road for traffic switch,
as required
Install safety barriers where needed
Implement traffic switch to facilitate staging of works, as required
Implement final property adjustments including ancillary works inside private
property and the final boundary fence
Landscape using backhoe, trucks and hand tools
New line marking, lighting and sign posting
Site clean-up and disposal of all surplus waste materials
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 62
Review of Environmental Factors
Remove construction traffic management and open new works to traffic.
Construction of rock cuttings
The indicative rock cutting construction sequence for the proposal is as follows:
Establish environmental exclusion zones including the limits of clearing
Install temporary erosion, sedimentation and drainage controls
Establish stockpile areas
Establish construction phase traffic control, including temporary traffic signs,
safety barriers, line marking changes and similar
Remove property fences and erect temporary security fence as required
Mark trees requiring removal and carry out inspection by suitably qualified
ecologists
Clearing of vegetation
Install protection screening where required
Stripping and stockpiling of topsoil using machinery such as grader and
excavators. Topsoil material to be removed by trucks as generated and taken to
a stockpile site
Excavation of the rock cutting by one of two possible methods:
Rock to be pre-cut in a grid pattern using an excavator mounted rock cutting
blade. Blocks of rock pulled out from the rock face one at a time using an
excavator mounted ripping claw and hauled by hauling trucks to the stockpile
site
Rock ripped using an excavator or similar vehicle. Material to be ripped in
layers until it reaches designed level. There is one rock cutting to be
excavated using this method which requires approximately 250 metres of cut
in length and around 10 metres in height. Material to be removed by trucks as
generated and either directly reused on site
Construct pavement once design level are achieved
Stabilise exposed areas
Site clean-up and disposal of all surplus waste materials
Remove construction traffic management and open new works to traffic.
Drainage works
The construction sequence for drainage works would generally involve:
Access tracks – all tracks would be within the construction footprint, and have a
layer of clean fill to create a stabilised surface and installation of sediment and
erosion controls
Pre-construction culvert inspections
Installation of erosion and sediment control facilities to minimise the impact on
receiving water quality
Construction of diversions to direct flows around the existing culverts
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 63
Review of Environmental Factors
Excavation of culvert base slabs
Construction of the culvert foundations using granular material, piers or piles,
depending on the subsoil condition
Pouring of culvert concrete base slab
Installation of box culvert precast U-units on base
Placement of fill over units to form the base course for the road foundation
Infilling of the diversion channel with compacted fill and re-establishment of
drainage flows into the new culverts
Where necessary, scour protection would be provided upstream and/or
downstream of each culvert
Stabilise exposed areas and revegetate
Site clean-up and disposal of all surplus waste materials.
Construction hours and duration
Construction is expected to take about 30 months to complete, weather permitting. At
the time of preparation of this REF, funding for construction of the project had yet to
be confirmed and identification of a specific commencement date is therefore not
possible. However, construction is expected to follow that of the Mona Vale Road
East Upgrade Project.
The workforce would comprise up to 50 personnel during peak periods.
Construction of the proposal would be undertaken primarily during standard working
hours in accordance with the Interim Construction Noise Guideline as follows:
Monday to Friday: 7am to 6pm
Saturday: 8am to 1pm
Sundays and public holidays: no work.
It is anticipated that some work would need to occur outside of the standard working
hours to minimise traffic impacts, including utility adjustments, asphalting and line
marking. Work outside of standard hours (if required) would be in accordance with
Environmental Noise Management Manual Practice Note vii – Roadworks Outside of
Normal Working Hours (Roads and Traffic Authority, 2001) the Interim Construction
Noise Guideline (Department of Environment and Climate Change, 2009) and the
safeguards contained in this REF. This would include notifying the local community of
any works planned to be undertaken outside standard construction hours.
Plant and equipment
Construction of the proposal would be undertaken using standard road project
construction techniques. Typical plant and equipment that may be used during
construction includes items identified in Table 3-4.

Earthworks
The proposal would require numerous sections of cut and fill along most of the
alignment. Fill would be required for the earth platform described in Section 3.3.1,
behind retaining walls, and at various locations for the length of the proposal.
Current estimates are that about 138,300 cubic metres of cut material would be
generated from the proposal. About 169,400 cubic metres of fill would be required
and would preferentially be sourced from suitable cut material from the proposal.
Current estimates identify about 31,100 cubic metres of additional fill would be
required. The Harvey Road extension would generate about 37,600 cubic metres of
cut material and would require about 26,300 cubic metres of fill material.
Other excavated materials would likely include milled asphalt, select material and
topsoil.
An assessment of the earthworks volumes required for both Mona Vale Road East
and Mona Vale Road West identified that there would be a surplus of material
generated from Mona Vale East. The assessment found that the rock material won
from cuts in Mona Vale East would be suitable for use as select material, reducing
the amount of fill required in Mona Vale West. The preliminary assessment has not
considered topsoil stripping or replacement.

General earthworks (cut/fill) 128,500
Imported/borrowed material 49,800
Source and quantity of materials
Materials would be sourced locally where possible, with the majority of materials to
be sourced from the Sydney region.
Table 3-7 shows the estimated quantities of particular materials which would be
required by the proposal.
Table 3-7 Estimated material quantities
Material type Quantity (m3)
Select material 30,000
Road base (base course) 4075
AC14 (asphalt base coarse) 5015
AC20 (asphalt base coarse) 17,220
Light duty pavement base (base for pathways, etc) 1880
Concrete footpath 1880
Water for construction would be sourced from available hydrants in the area. The
required quantities of water are not yet known, however the use of material such as
ready mix concrete (required for pavement and kerbs) would reduce the amount of
water required during construction. Water would also be required for compaction of
pavement layers, such as select layers to adjust the moisture content, and for dust
suppression.
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 67
Review of Environmental Factors
Surplus material that is not able to be used on-site as part of the proposal would be
reused or disposed of in the following order of priority:
Transfer to an approved Roads and Maritime temporary stockpile site for future
use during projects or routine maintenance
Transfer to a Roads and Maritime approved site for reuse on concurrent
private/local government project (with appropriate approvals as required).
Disposal at an approved materials recycling or waste disposal facility
As otherwise provided for by the relevant waste legislation.
The process for management of excess material would be detailed in a Resource
and Waste Management Plan (RWMP) that would form part of the CEMP.
Traffic management and access
Vehicle movements
Maintaining traffic flow during construction is a key consideration for construction
traffic planning for the proposal. It is expected that a maximum of 50 construction
vehicles per day during the peak construction period would be required. The majority
of these vehicles would undertake trips either predominantly or entirely along the
Mona Vale Road corridor and local roads being upgraded as part of the proposal.
Traffic management
A Traffic Management Plan (TMP) would be prepared in accordance with the
document Traffic Control at Worksites (Roads and Traffic Authority, 2010) and Roads
and Maritime Specification G10–Control of Traffic.
The TMP would provide details of traffic switches and the traffic management
measures to be implemented during construction to ensure that traffic flow on the
surrounding network is maintained where possible. The TMP would also ensure the
safe separation of workers on site from vehicles on Mona Vale Road.
The TMP would detail specific haulage routes that construction traffic would follow
throughout the construction phase.
At this stage of planning, it is intended to maintain two traffic lanes (one each way)
during construction, however, a reduced speed limit may be introduced for the
duration of works.
Access
While the location of the site compounds and stockpile locations is yet to be
confirmed, based on the preliminary locations selected, it is considered likely that the
majority of construction related traffic would be contained within the local area.
All property accesses would be maintained throughout construction.
Ancillary facilities
At the present stage of planning, it is proposed to use the same site office location for
the Mona Vale Road East Upgrade project. This would be used for worker amenities,
project related office facilities, storage of equipment.
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 68
Review of Environmental Factors
Alternative or additional sites may be identified during detailed design or at a later
stage during construction. The selection of any additional or alternative site
compounds and temporary stockpile sites would also be considered against the site
selection criteria detailed in Table 3-8. Should these sites be located outside of the
existing proposal construction impact area, additional environmental assessment
would be undertaken.
Table 3-8 Selection criteria for stockpile and compound sites
Selection criteria
Location Located within the project study area or directly adjacent to the
proposal
Stockpiling sites are not to be located on slopes with a gradient
greater than 2:1 horizontal to vertical.
Locate other compound sites on relatively level ground.
Services Locate site offices where they can be easily serviced with electricity
and potable water.
All ancillary sites are to have direct and safe access to the road.
Environmental Wherever possible, sites are to be located above the 1 in 100 year
flood level.
Locate facility more than 50 metres from watercourses*
No substantial vegetation clearing. Ancillary sites are to be located
on land of existing low conservation significance for flora and fauna.
Wherever possible, sites are to be located and designed to satisfy
noise and vibration management levels, relevant to the noise
catchment area, and vibration goals at the sensitive receiver (or
building, in the case of vibration). If noise management levels or
vibration goals cannot be met, feasible and reasonable mitigation
measures, the restriction of hours of operation and/or negotiated
agreements with affected parties would be considered.
Heritage Locate on sites that have a low likelihood of having Aboriginal or non-
