1 Introduction This Environmental Construction Method Statement (ECMS) outlines all works associated with the pre-construction, construction and post construction considerations of the F3 Interchange. This ECMS provides specific management measures for the early works associated with the F3 Interchange.

As the construction compounds, grout plant and the specific design changes relevant to the F3 areas are subject approval, these aspects of works cannot commence until DECCW approval is awarded and EMR certification of the revision of this ECMS.

This version of the ECMS does however describe all activities in broad terms. This document:

incorporates the relevant Ministers Conditions of Approval, Aug 2007, the modification, June 2010, and the Environmental Protection Licence (no:13296), July 2010

addresses the requirements of the Minister’s Condition of Approval 30 for the Hunter Expressway project,

reflects the requirements of the Hunter Expressway Alliance (HEA) environmental management system (as detailed in the Construction Environmental Management Plan),

incorporates the management measures from the relevant CEMP sub-plans, including the post-planning approval revisions;

management requirements as outlined in the , Dept of Industry and Investment NSW (formerly NSW Fisheries and DPI), DECCW, and RTA guidance documents; and

describes the environmental management measures relating specifically to the construction activities and potential environmental issues.

This ECMS has been prepared as a practical environmental management tool for use by all HEA personnel and subcontractors and incorporates the assessment of the environmental and community risks for these works. The specific environmental and community management controls developed and detailed in the ECMS, include the following key information:

Key site and management personnel - responsibilities and contact details.

Operating hours.

Construction details – activities, staging and schedule.

Objectives and targets – monitoring requirements, criteria and procedures.

Action tables/plans – inspection and test plans with actions, responsibilities, training, timing, reporting, monitoring/auditing and checklists.

Site drawings - Site layout, monitoring locations, erosion controls, noise barriers, discharge points and limits of clearing.




1.1 ECMS overview The ECMS #1: General Construction will be required for all construction sites. This activity specific ECMS provides specific requirements for the construction of the F3 Interchange.

The F3 ECMS will also need to be used in conjunction with the following:

ECMS 2: Clearing and Topsoil Management

ECMS 3: Construction Site Compound

ECMS 5: Access Tracks

ECMS 6: Treatment of Mine Voids

ECMS 8 –Temporary Waterway Crossings

The Site Supervisor in consultation with the QA Manager will determine which ECMSs are required for each work site. Refer to the overview map contained in ECMS 1 for an overview of all ECMSs.

1.2 ECMS attachments

Attachment A of this ECMS contains an Environmental Control Plan (ECP). The ECP contains:

Specific tables with environmental management measures; and a

Cadastral and air photo base of the F3 with an overlay of site boundary, vehicle routes, flora and fauna, aboriginal and historical heritage and environmental controls. .

Attachment B of this ECMS contains the indicative construction schedule.

ECPs are to be read/ implemented in conjunction with the ECMS document and relevant reference documents and are for day-to-day reference for managing activities on the individual sites. The ECPs have been designed as A3 and/or A1 drawings for attachment to site shed walls.

As detailed drawings are progressed for areas covered within this ECMS, further ESCPs will be developed.

Following approval of the F3 design changes and the subsequent revision of this ECMS, the revised ECMS will include Progressive Erosion and Sediment Control Plans (PESCP) for:

Grout batching plant

Construction Compound

1.3 Key reference documents to ECMS The development of this ECMS has been guided by detailed management plans and reports prepared for the project’s Construction Environmental Management Plan (CEMP). Impacts and mitigation measures from these plans and reports that are relevant to the F3 Interchange works have been incorporated into this ECMS. The relevant CEMP sub-plans listed in Table 1.1 and the specific references relevant to the F3 Interchange works are listed in Table 1.2. the documents will be referred to as needed for specific information for day-to-day worksite activities.

2 Scope of works This ECMS describes all construction works for the F3 Interchange for the construction of the 13 km expressway project from the Newcastle Link Road interchange with the F3, through to Buchanan.

Additional management requirements associated with the construction compounds, grout batching plant and areas associated with the route design changes, will be incorporated into this ECMS once approved through either the Consistency Review Reports (with DECCW approval) or Risk Assessments (with RTA approval).

Construction of the F3 Interchange will require the following activities:

All works associated with the preparation and construction of the F3 Interchange from the roundabout at the intersection of Newcastle Link Road with Cameron Park Drive to the western side of the F3 Freeway west of the Minmi Creek crossing.

All on/off ramps requiring upgrade and/or construction for the purposes of the project.

Nine bridges – eight new and one upgraded.

Construction compounds (2-3 compounds).

2.1 Overview of all F3 activities The F3 area along the Hunter Expressway alignment is illustrated in ECMS 1, Appendix B in the ECMS Overview Map. A detailed map of works at the F3 is provided in this ECMS as Attachment A.

The F3 Interchange is a large component of the HEA project and it is anticipated that construction works will be ongoing at this location for approximately two years. Due to the complexity of this area of the project, the construction of the F3 Interchange will be undertaken in a number of stages, roughly aligned into the following areas of work:

Note: as indicated below some aspects of the works are subject to approval of the design change from the EA and as such will be described in greater detail in the next revision of this ECMS.

1. Construction of temporary site access points on Newcastle Link Road and within the median of the F3.

2. Establishment of grouting batch plant on site (design change from EA).

3. Mine void treatment to stabilise the areas under the bridges (new and existing) at the interchange.

4. Upgrade and construction of the Newcastle/Branxton to Sydney on-ramp to the F3 Freeway. (where Branxton to Sydney ramp merge –this is a design change)

5. Upgrade and construction of the new Sydney to Newcastle/Branxton off-ramp from the F3 Freeway.(design change up to where it meets the main alignment)

6. Bridge Construction.(BW004 –design change, however eastern abutment and the interchange Branxton to Sydney ramp expected to be within the existing footprint)

7. Widening and upgrade of Newcastle Link Road between the F3 and existing roundabout. (some of the footprint has change, however western end unchanged)

8. Construction of new mainline roadway from the F3 to just west of Minmi Creek.(bridges changed and ramp location over Minmi Creek have changed)




Permanent sediment control basins will be installed prior to commencement of topsoil stripping and as part of the earthworks phase. Temporary erosion and sedimentation controls shall be installed prior to construction when permanent measures cannot be installed. Each of the work areas are described in more detail below.

Note: This ECMS does not include mine void treatment required in the vicinity of the F3 Interchange or the associated grout batch plant and facilities. For details concerning mine void treatment and the batch plant, refer to ECMS 6 – Mine Void Drilling and Grouting (HEA-CMS-GL-ENV-006-01-00 or updated version).

2.2 Scope of works relevant to this revision of the ECMS This revision of the ECMS covers the early works required to commence in January 2011. They include the following activities:

Site clearing within the approved project boundary for the F3 Interchange

Widening of existing tracks and construction of new access tracks for site entry for mine void treatment

2.3 Construction of Site Accesses – Newcastle Link Rd and F3 (commencing Jan 2011)

Two main site access points will be constructed to allow access to the work areas – one within the F3 median itself and one on Newcastle Link Road. The works associated with the F3 median are subject to a risk assessment and thus RTA approval will be sought prior to commencement.

The F3 median access involves the construction of temporary deceleration and acceleration lanes within the F3 median, plus the installation of temporary concrete barriers on the shoulder of the F3 to protect workers during construction of the bridge piers and the mine void filling works. Construction of the temporary deceleration and acceleration lanes and installation of barriers has to be undertaken at night during lane closures of the F3 itself. It is an RTA requirement for this project that lane closures on the F3 not be effected during daylight hours, hence the construction works are required to take place at night.

This work will include typical road construction activities, such as traffic control, excavation, pavement construction and mobile cranes to place the concrete barriers. Night works also require the use of lighting plants for work area lighting. Once the site access to the F3 median is complete, all construction works (and mine void filling works) within the median can be done during normal daylight working hours.

The site access on Newcastle Link Road (including the existing Sydney-Newcastle off ramp) will provide long term safe access to the construction site to the west of the F3. This involves re-aligning traffic, temporary asphalt, installation of temporary concrete barriers, revised line marking, saw cutting and/or milling the existing asphalt and demolition of part of the existing median barrier on the existing bridge and Newcastle Link Road.

As most of the work on Newcastle Link Road will be in very close proximity to live traffic, the majority of the access point construction work will be at night time under lane closures. Night works also require the use of lighting plants for work area lighting. Once the access point has been constructed, it will allow safe access to all works to the west of the F3 during normal daylight working hours.




This work area is located within the existing footprint and is approximately 1km from the nearest residence. See section 2.11 for out of hours works and the Environmental Control Plan, Attachment A for the notification and management measures.

2.4 Grout batching plant (commencing Feb 2011)

A grout batching plant and associated sheds and amenities is required for the supply of grout for mine void stabilisation works. The grout batching plant will be located on the eastern side of the Newcastle to Sydney on ramp as shown in Attachment A. The location is contained within an area already assessed for the project however some clearing will be required. A design refinement consistency assessment has been prepared to ensure the requirements of MCoA 129 are met.

The general requirements for the grout batching plant and associated controls are covered in ECMS #6 - Mine Void Drilling and Grouting (HEA-CMS-GL-ENV-006-00-01). An access will be required to access the grout plant by construction vehicles. The access will utilise existing an existing property access within the adjacent Cameron Park Industrial Estate via Stenhouse Drive. The Local Authority has advised that they have no objection to this access and the use of Stenhouse Drive within the industrial estate as an access point to the grout plant area. The power line easement through this area will also be utilised as a parking area for the F3 Interchange construction workforce to minimise clearing in the area. The car parking area has been assessed in the Consistency Review Report currently being prepared for the grout batching plant.

As the grout batching plant is subject to the approval of the Consistency Review Report, approval regarding out of hours works will also be sought as part of this submission.

2.5 Mine void treatment The mine void drilling and grouting required around the F3 Interchange is covered under ECMS 6 – Mine Void Drilling and Grouting (HEA-CMS-GL-ENV-006-00-01) which will be updated to include the works in this location.

2.6 Newcastle/Branxton to Sydney on-ramp (commencing Feb 2011)

The existing Newcastle-Sydney onramp will need to be rebuilt and a new section added to take traffic from Branxton to Sydney. During this construction work, the existing ramp will be closed and all traffic will be diverted via Cameron Park Drive to the onramp at George Booth Drive. The existing ramp will be closed for around 6 months while the new ramp is being built, after which the new ramp will be opened to the public.

Works include significant excavation (for the Branxton-Sydney section) and embankment construction as the level of the existing ramp has to be raised to suit the new road alignment. As the existing ramp will be closed to traffic, the majority of the works will be constructed during normal daylight working hours. Installation of concrete barriers, line marking, sign installation and other activities associated with the traffic switches will need to be conducted at night.

As the new road alignment is over the current ramp but is actually cut into the existing ramp, the new road alignment requires this ramp to be closed for around 9 months and Sydney-Newcastle traffic diverted off at George Booth Drive. Detours will be implemented in consultation with the RTA and local council. Prior to this, the two bridges over the F3 Freeway and the new cut and cover tunnel (bridge 5) under the new main alignment will be constructed and the pavement to those bridges completed.




All new construction works on the new ramp will be done off line and during normal working hours. Installation of concrete barriers, line marking, sign installation and other activities associated with the traffic switches will need to be conducted at night. This work is not expected to generate any audible noise at the nearest sensitive receivers.

2.7 Bridge Construction (commencing Mar 2011) Works at the F3 Interchange will require the construction of eight (8) new bridges and upgrading the existing bridge over the F3. Four are concrete girder bridges, Bridge 4 and Bridge 6 are steel girder bridges (depending on design development) and Bridge 5 will be a cut and cover underpass under the future main alignment of the Hunter Expressway with precast bridge planks forming the roof of the underpass.

Piling is required for each of the bridges at the F3 Interchange. All piling is bored piling and ranges in size from 0.75m diameter up to 2.5m diameter. Central piers and headstocks will be constructed within the F3 median for bridges 2, 3 and 4. Bridge 4 has two additional piers, one near the F3 northbound shoulder and the other near the eastern abutment of the existing NLR bridge. The other bridges are all single span bridges with either standard concrete abutments or reinforced earth wall abutments.

Note that most concrete will be made on site at the project’s structural concrete batching plant (adjacent to the main project office compound), delivered in concrete agitators and will be placed using the normal methods (concrete vibrators, concrete pumps and so on). Some concrete placement will be required at night during road closures, particularly for the bridges over the F3 (bridges 1, 2, 3 & 4). As some components of bridge construction are subject to the approval of the Consistency Review Report, approval regarding out of hours works will also be sought as part of this submission.

Girders will be manufactured off site and will need to be transported to the site and then lifted into place with cranes ranging in size from 200t hydraulic cranes potentially up to a 750t crawler crane. Transport of the bridge girders will be at night under specific transport permits, as the girders range from around 12m through to 50m in length. The longer girders will be transported individually due to their length and weight and will be transported to site at night due to the traffic permit restrictions. Steel girders will be up to 50m long, up to 3.2m wide and weigh up to 100t each. There will be around 16 deliveries of steel girders to site. The majority of the concrete girders will be around 35-38m long, up to 2.7m wide and weigh up to around 80t. There will be around 14 concrete girders delivered. Bridges 4 and 6 also require a precast slab system to be lifted into place once the main bridge girders have been erected.

Girders, precast slabs, precast barriers and anti-throw screens for Bridges 2, 3 and 4 will need to be placed out of hours as the F3 Freeway will need to be partially closed to traffic during this work. One carriageway (side) of the Freeway will be closed at a time with traffic diverted to the other side via the centre median cross-over points. Once the girders have been lifted into place, decking and drainage will be installed followed by erection of safety screens and barriers.

The remaining bridges can be constructed away from traffic and will all be done during normal daylight working hours.

The bridges over Minmi Creek all have piled abutments with reinforced earth walls and are all single span bridges. Exclusion zones, which are ‘male only sites’ due to aboriginal heritage significance, apply around the Minmi Creek area and are marked on the ECP in Appendix A. All works around the Minmi Creek area will be managed to avoid impacts on the grinding grooves, stone arrangements and the weirs within the creek exclusion area.




Due to the exclusion zones, all construction work will be done outside the exclusion zones except where agreed for specific activities by the Awabakal Local Aboriginal Land Council (ALALC). The tops of some of the trees within the Minmi Creek exclusion area will have to be trimmed where the bridge will be, so specific methods and access for this work will be agreed with the ALALC.

2.8 Newcastle Link Road Upgrade (commencing Feb-Mar 2011)

Newcastle Link Road (NLR) will be widened, re-aligned and most of the existing pavements re-constructed to take the traffic for the new Hunter Expressway. Works will include significant traffic staging, connecting to and extending existing drainage lines under NLR, construction of new pavements both off-line from traffic (behind temporary concrete barriers), pavement construction at night under lane closures, installation of concrete barriers and signage for traffic switches at night and general earthworks activities (excavation and compaction).

The Traffic staging will affect both directions along NLR from the existing roundabout all the way to the F3. The existing drainage lines will need to be extended or re-laid, which will require saw cutting the existing pavements to access the pipes. Along the northern edge of NLR between the existing Beresfield-Newcastle ramp and the existing roundabout, the road pavement will be rehabilitated – the old pavement will be milled and the pavement will be built up with new material and resurfaced. .See section 2.11 for details on out of hours works.

2.9 Earthworks (commencing in Feb-Mar 2011) There are a number of large earthworks operations associated with the on and off ramps and bridge abutments, including:

120,000 cubic metres of cut for the Sydney to Newcastle/Branxton off ramp

90,000 cubic metres of cut for the Sydney to Newcastle off ramp

20,000 cubic metres of cut for the Newcastle Link Road

30,000 cubic metres of cut for the Branxton to Sydney on-ramp to the F3 Freeway

100,000 cubic metres of fill and reinforced earth backfill materials around the bridge abutments (primarily near Minmi Creek), a large quantity of which will be imported

All erosion and sediment control for earthworks activities will be managed in accordance with the relevant sub-plans identified in Table 1.1. A combination of temporary and permanent control measures (such as permanent sediment basins) will be used during construction.

2.10 Hours of operation Normal construction hours apply to the activities included in this ECMS. These hours are:

Monday to Friday 7:00 am – 6:00 pm

Saturdays: 8:00 am – 1:00 pm

Sundays & Public Holidays – no work

2.11 Out of hours Out of hours work will be required for a number of project components such as lifting in the girders for the bridges over the F3 Freeway, pavement construction works or other works where working in close proximity to live traffic. Where working in close proximity to traffic, activities are typically only




permitted at night when traffic levels are low. A number of activities are approved out of hours based on the assessment in the NVMSP (July 2010), Appendix A and the description of the activities in section 7.3 & 7.4. These activities are:

Concrete paving Asphalting, Traffic Control, Signage, Line Marking (for Traffic switches) Saw cutting of concrete pavements Concrete batching plant and grout batching plant production Material delivery for concrete and grout batching plant production

Impacts on the nearest sensitive receivers for the F3 are located at Seahampton. Appendix A of the NVMSP assessed the noise impacts for the construction of:

Main bridges and intersection; and Main carriageway

The maximum anticipated noise exceedance for evening and nightime works is 4 dBA, based on the nearest receiver at 580m from F3 HEA works.

Due to the F3 design changes and therefore the revised location of work sites, further assessment of impact at the nearest sensitive receivers will be determined as part of the Consistency Review Report. Any noise generating activities not assessed as part of the NVMSP, and not permissible under the EPL s3.2 will require assessment to determine whether audible at the nearest sensitive receiver during evening and night time operations. When exceedances are anticipated, a written approval will be sought from DECCW prior to commencement of out of hours works.

2.12 Site Compounds (commencing Feb 2011)

A small site compound will be located adjacent to the grout batch plant, which will include meal rooms, change and toilet facilities to accommodate between 30-60 staff. An assessment against the MCoA 129 will be incorporated into Consistency Design Review.

A small construction compound will also be located to the west of the F3. This will include meal rooms, change and toilet facilities for workers in that area. This compound will be located within the footprint of the new road and will be relocated as required to fit in with the construction sequence without requiring additional clearing. An assessment against the MCoA has been undertaken for the Consistency Review Report, and will be incorporated into the revised ECMS.

An additional construction compound may also require for median works of the F3 for a maximum of 20 people. An assessment against the MCoA will be undertaken, and incorporated into the revised ECMS when necessity is confirmed.

2.13 Site rehabilitation and restoration

Rehabilitation for the grout batching plant site and any compound site(s) will be undertaken on completion of works. Where possible, the rehabilitation strategy adopted for the site will seek to improve on the current condition of the area; however, this will depend on future use of the land.
