Construction Traffic Management Plan Turitea Wind Farm TWF-PM-PLN-0012-05_CTMP
1 Introduction
This Construction Traffic Management Plan (CTMP) has been prepared in compliance with the Resource Consents for the Turitea Wind Farm project. The wind farm is located near the city of Palmerston North in the region of Manawatu – Whanganui, New Zealand.
The plan incorporates information from the appointed Engineering, Procurement and Construction (EPC) Contractor for the project (Vestas-New Zealand Wind Technology Ltd) and also the project’s Balance of Plant (BoP) Contractor (Downer New Zealand).
Mercury NZ Ltd (the Employer) have Consent for 60 Wind Turbine Generators (WTG’s), a 220/33kV substation and a 22kV transmission line of approximately 15km in length connecting the wind-farm substation to the existing Linton substation.
The first phase of the project involves construction of the northern portion of the consented wind farm (the Northern Turbine Zone). This includes 33 WTGs, each of 3.6MW, at the northern end of the site connected to the substation and transmission lines.
The second phase of the project (the Southern Turbine Zone), includes an additional 27 WTGs, with the substation connection being considered at a later date. This second phase of the project will be subject to a new or substantially revised CTMP.
Of particular note, is that neither the WTG’s nor the substation in the Northern Turbine Zone require any access from Greens Road. This CTMP therefore only addresses access off Pahaitua-Aokautere Road, that is South Range Road (SRR) and the Eastern Access.
Construction of the Northern Turbine Zone will require the existing South Range Road (SRR), which is a public road in part, to be both re-aligned and improved.
Additionally, the existing SRR entrance off Pahaitua-Aokautere Road will be relocated to provide a new upgraded entry point further south away from the tight bend.
The intention of the eastern access is that it shall be utilised for the turbine blade deliveries only. During construction works, the access will be barricaded closed to mitigate unauthorised access.

1.1 Purpose and objectives of the CTMP
The CTMP has been prepared to manage, mitigate and monitor the effects of construction traffic on the local road network during the construction of the Turitea Wind Farm (Northern Turbine Zone).
The objective of the CTMP is to detail the best practicable option to avoid adverse safety and efficiency effects caused by construction and to mitigate any such effects should they occur.
The CTMP identifies how construction traffic will be managed to: • Protect public safety; • Minimise delays to road users; and • Inform the public about any potential impacts on the road network.
The CTMP includes detail on the following: • Construction activities that might create road safety and/or efficiency effects; • Management procedures and mitigation methods; • Roles and responsibilities; • Training of staff in relation to traffic management; • Monitoring methods; and • Methods for managing complaints and keeping compliance records
All Contractors and Sub-Contractors engaged on the project shall be required to conform to the requirements of this CTMP.

2 Project Details
Key traffic related details for the project are captured in the Traffic Design Group Ltd Transportation Assessment Report, dated August 2008. Key changes that have occurred since then are:
• The overall number of turbines approved by the Board of Inquiry is less than what was assessed;
• The project has been divided into two portions, with this current project only involving the Northern Turbine Zone, and only involving access from the north;
• The size of the turbines has increased, such that the 44m blades envisaged for transport to the site will now be 55m long. The turbine components will be landed at Napier Port and trucked via SH2 to Pahiatua and then up to the access points on the Pahiatua- Aokautere Road. These effects are detailed in the Transport Feasibility Study undertaken by Tranzcarr Ltd;
• The Manawatu Gorge has been permanently closed, meaning traffic flows on the Paihiatua-Aokautere Road have increased from around 1,500 vehicles per day (vpd) to around 4,450 vpd and 13% HCV. In response to this, interim safety measures have been installed at the South Range Road intersection to improve safety during the design and planning stage.
• In the event of a traffic accident or coordinated planned works on Saddle Rd, construction traffic shall be minimised and/or rescheduled (if required) to mitigate congestion on Pahiatua-Aokautere Road. The Mercury Turitea Project free phone number will receive the initial notification and appropriate mitigation measures will then be implemented by the site construction management team.

3 Construction staging and sequencing 3.1 Works Programme
Due to the nature, scale and programme of the project, construction will be undertaken on a number of fronts or work faces, such that different construction operations will, at times, be simultaneously progressed across all construction zones. As each construction zone is accessed, the approach will involve:
• Preparatory works – Initial works to enable Establishment Works and Construction Work, such as:
o Site Survey; o Investigations (including geotechnical investigation); and o Monitoring; • Establishment works - Progressively opening up and establishing the site, including:
o Land disturbance activities to establish site access, access tracks, construction yard and accommodation areas, laydown areas and spoil disposal sites and associated erosion and sediment controls.
o Construction and/or widening of roads/tracks to access construction areas and install sediment control measures (e.g. sediment control ponds);
o Vegetation clearance o Establishment of construction yard and accommodation areas; o Establishing full width access tracks/haul roads; o Installing remaining erosion and sediment controls • Main Construction works – Construction works, including:
o Temporary and permanent drainage installation; o Bulk earthwork (including cut and fill activities) o Wind turbine foundations; o Pavements and Surfacing; and o Site reinstatement;
The figure below shows the indicative construction programme and sequencing for the project.

3.2 Working Hours
Standard working hours will be as follows:
• Monday to Saturday: 0730 – 1800
There will however be some construction activities undertaken outside the standard working hours. These activities may include;
• Works on the existing Pahiatua Aokautere Road, including construction of site access points at the start of the project.
• Afterhours material and plant delivery, including equipment and materials where the transport of oversize loads outside working hours will be less disruptive;
• Early morning concrete pours; and
• On-site servicing of plant and equipment to minimise impacts on construction programme.
Any activities undertaken outside the standard working hours will be in compliance with the project Construction Noise Management Plan. However, in general, extended working hours will be as follows:
• Monday to Saturday: 0630 – 2000 • Sunday: 0730 – 1800
Page 17
Construction Traffic Management Plan Turitea Wind Farm TWF-PM-PLN-0012-05_CTMP
4 Roading upgrades 4.1 South Range Rd – Pahiatua-Aokautere Rd
During the project, all traffic (with the exception of WTG blade over-dimensioned loads) will enter and exit site through the new entrance between the South Range Road (SRR) and Pahiatua-Aokautere Road. This improvement is important as the current intersection is located adjacent to a blind corner which makes the entrance and exit dangerous and not fit for construction traffic and the general public. As noted on the construction programme, the construction of this new intersection will start in September 2019. To facilitate construction of the new entrance, two TMP’s will be required as detailed in Section 1.2 above. The first of these TMP’s, for the road widening on Pahiatua-Aokautere Road, has been submitted to PNCC and approved on the 27th August 2019 (Ref: CAR R614855). Please refer to Appendix D for further details Work on the other TMP’s identified is on-going and these documents will be lodged with PNCC for approval with sufficient notice in order to meet the timelines identified in the works programme. Following the closure of the old South Range Road, barricades will be placed preventing public access with signage advising public of the changed layout.
Page 18
Construction Traffic Management Plan Turitea Wind Farm TWF-PM-PLN-0012-05_CTMP
4.1.1 Existing Intersection
The existing intersection is used by the land owners who live on SRR, hunters who have access to the reserve and by the public, although there is very little use by the general public. After the completion of the new access, the existing entrance will be physically closed as required by Condition 54.3 of the Consent. With the need for heavy plant to operate along and across South Range Road, it is proposed to limit entry to the new access to the PNCC Pest Controller, Ecology Monitoring personnel, Iwi representatives, and workers with legitimate access requirements only to reduce the risk of interaction with construction equipment during construction.
The personnel concerned will continue to have access following an induction and the establishment of communication protocols for movement along SRR. The personnel noted above will also be able to communicate with construction plant via the same radio frequency.
Existing hunting licences currently in-place are to be suspended for the duration of construction. Additionally, existing ‘lifestyle’ landowners on SRR are relocating and public access does not extend into the Turitea Reserve, With all of the above in mind, these initiatives are considered to provide a workable solution which will provide the safest way to manage the substantial earthworks that are to occur along SRR. This approach also mirrors that taken with the development of previous wind farms along the Tararua Range.

Construction Traffic Management Plan Turitea Wind Farm TWF-PM-PLN-0012-05_CTMP
4.2 Pahiatua-Aokautere Road Eastern site access
The current Pahiatua-Aokautere Road has sharp corners and is too narrow for trucks to deliver the 55 metre blades through the main entrance. As such, an Eastern Site Access (Figure 4.2) will be built near WTG 09. This access will be built in general accordance with “Pahiatua-Aokautere Road – Eastern Site Access (TDG drawing 8488-3W1, Sheet 9, Revision A)”.
Figure 4.2- “Pahiatua-Aokautere Road – Eastern Site Access (TDG drawing 8488-3W1, Sheet 9, Revision A)”
This access will not be needed until the turbine components are delivered in February 2020. The detailed design for this access will therefore be designed and reviewed in the interim period, with the details to be included in a revision of this CTMP. Engineering designs will also be submitted for approval by Tararua District Council.

Construction Traffic Management Plan Turitea Wind Farm TWF-PM-PLN-0012-05_CTMP
4.3 Necessary road improvement for over- dimension loads (ODLs)
In addition to the Pahiatua-Aokautere Road - Eastern Site Access, further road improvements will have to be undertaken to facilitate the movement of over-dimension loads (ODLs) to the site.
4.3.1 South Range Road (SRR)
The entire extent of SRR will be improved as the road and corners will be cut and the road straightened to facilitate the delivery of large WTG components. Furthermore, to facilitate site traffic, the road will be widened to 5.5 metres with a base graded aggregate for roadbed. Additionally, a ditch will be running next to the new access track to maintain erosion control. Please refer to the road cross section figure below.
Figure 4.3 – South Range Road cross section after improvement
Engineering drawings and specifications, detailing these upgrade works, will be submitted for approval to the relevant authorities in phases in order to meet the timelines identified in the works programme.

Construction Traffic Management Plan Turitea Wind Farm TWF-PM-PLN-0012-05_CTMP
4.3.2 Improvements to the public road network
Few improvements to the public road network are needed to accommodate the traffic associated with the wind farm. The extent of road improvements required to accommodate over dimension loads will be determined at the detailed-design stage with a delivery route test-run, completed using a simulated blade-delivery trailer. The trailer will be extended to the same dimensions as required to carry the blades and the blade overhang from the rear of the trailer simulated with a length of PE pipe (that can be moved if required to pass an obstacle encountered). Prior to conducting the test-run, the necessary permit applications will be made and approved by the relevant authorities. The test vehicle will be accompanied by certified pilots to control traffic, comprising two front and one rear, in line with the requirements of the Vehicle Dimension and Mass Rules. The test-vehicle will drive the delivery route from the port of Napier to site and test the known pinch points to determine the full extent of road modifications and street furniture removal required. Traffic will be stopped by the pilot vehicles momentarily at these pinch points as required. As an additional aid to traverse pinch-points, the blade trailer will have manual-steering functionality allowing the rear trailer wheels to be adjusted to move the load further away from obstacles. As noted in the Tranzcarr Feasibility Study included in Appendix C, few pinch points have been identified on the route and therefore, the amount of modifications to the public road network, is not envisaged to be substantial. By testing the route, modifications are kept to a minimum. The test-run has been conducted by experienced professionals from Tranzcarr who will have conducted many similar operations in the past. The test-run was undertaken using a mock blade scenario. Analysis of the test-run ‘pinch- point’ locations are currently being undertaken, with foreseen road widening works required on the Pahiatua-Aokautere Road north of the construction project. With the intention these works will be undertaken by Higgins in conjunction the Pahiatua-Aokautere Road safety improvements. All road modification work will then be designed and submitted to the relevant road controlling authority for approval in accordance with the applicable provisions of the Government Roading Power Act 1989 and the Local Government Act 1974. For further information, please refer to the Transport Feasibility Study for the V112 turbine components undertaken by Tranzcarr Heavy Haulage Ltd on behalf of Vestas which is included as Appendix C of this plan.
The delivery route test-run was undertaken on Thursday 12th September 2019.

5 Pavement Maintenance 5.1 South Range Road
As described earlier in this plan, the existing SRR will be rebuilt to a much higher standard than it currently is, with a wider cross-section, stronger pavement and drainage to prevent erosion.
Figure 5.1 – Current layout drawing of the turbines and the South Range Road improvement
Page 23
Construction Traffic Management Plan Turitea Wind Farm TWF-PM-PLN-0012-05_CTMP
Prior to the commencement of upgrade works, a video survey of the road will be undertaken to provide a record of the current condition and to provide a visual baseline to review the improvements against. Additionally, the construction team and PNCC will conduct a joint drive-over along SRR to understand the upgrade works in more detail.
In particular, the video survey and drive-over will consider the following items:
• Pavement surface condition • Drainage channels • Cut batters • Fills
An inspection and maintenance programme will be also be developed by the construction team to ensure that any damage to the road is identified and repaired to allow continuous use during construction.
During the construction period it is also anticipated that random condition inspections will be undertaken by PNCC (or their representatives) and that a final inspection will be undertaken prior to handover.

6 Construction activities that may generate traffic effects
The new SRR will be constructed off-line from the existing track, with most of the earthwork cut material being used on site. As such, there will be relatively little interaction with general traffic using the Pahiatua-Aokautere Road. The scope for adverse traffic effects associated with construction of the project will be limited in this regard.
The construction activities that have the potential to generate adverse traffic effects will be generally limited to:
• Operation of the site access points located along the Pahiatua-Aokautere Road (the new intersection between the SRR and Pahiatua-Aokautere Road and the Eastern Site Access), where there is a risk of potential interaction between a passing public vehicle and a project / construction vehicle entering or exiting the site; • These risks will be mitigated by constructing the new site entrances to allow project / construction vehicles to move off the road quickly – either to a new shoulder (SRR / Pahiatua-Aokautere Road entrance) or by recessing entrance gates to allow vehicles to park and open gates when locked (Eastern Site Access).
• Travel along the Pahiatua-Aokautere Road by construction vehicles (trucks and light vehicles. The increase in number of vehicles using this section of road has the potential to result in temporary delays to other road users. • Where necessary, these risks will be managed by the development of specific TMP’s as follows; o Rolling blocks/mobile temporary closures for heavy plant transporters or heavy slow turning trucks entering the old South Range Rd entrance (prior to construction of new SRR entrance) o VMS boards advising road users of changed road layout or potential increase travel duration o Coordination of heavy truck and trailer units (T&T) movement outside peak hours and/or rescheduling due to accidents or agreed planned works o Staggering of heavy truck and trailer units leaving e.g. quarry to mitigate a convoy of trucks arriving to site taking up the entire right hand turning lane and more. o Utilisation of the passing bay/waiting bay by site gate man with radio communication with truck drivers, e.g. risk of the right hand turning lane backing up
• External activities that may impact upon construction traffic movements (will be managed case by case), although planned event will be generally managed accordingly; o Widening works undertaken by Opus; Higgins weekly traffic management reports have been requested and will be sent by Kyle Russell (Project Manager) with our traffic movements strategy reviewed weekly and coordinated to mitigate adverse effects to road users o Maintenance works undertaken by Higgins; Notification from Higgins traffic management/maintenance team advising the project team of their upcoming

7 Construction Traffic Management 7.1 Philosophy
The overarching philosophy for the management of construction traffic during the Project is to: • Maximise safety of the project staff, pest controller and visitors travelling on site; • Enable construction efficiencies; • Minimise delays to the public and road users; • Minimise disruption to property access; and • Ensure appropriate access for emergency vehicles
This will be achieved by a high standard of: • Planning construction traffic movement; • Design of material stockpile/staging areas, taking into account site security access points and temporary traffic management; • Maintenance of roads, signs, and work sites; and • Communication internally within the Project, pest control and monitoring staff.

7.3 Management procedures
A number of procedures exist to identify and address risks associated with temporary traffic management during construction of the Project as outlined below.
7.3.1 Site Staff
All staff involved in the Project will attend a Project induction prior to the commencement of work to ensure a common basis for approaching their work. The induction will include environmental, health and safety and hazard management in relation to the Project area, along with temporary traffic control (refer to Section 10 of this CTMP).
Training will include the following: • Specific training will be provided to those involved in temporary traffic management as appropriate to their role and responsibilities. • Regular toolbox talks will provide a forum to reinforce and educate Project staff around specific temporary traffic control issues and actions during the Project. • The STMS will also conduct briefings on-site prior to every TTM operation (for the intersection upgrade works) to identify hazards pertaining to the work site and controls to be implemented to protect the safety of Project staff and public.
7.3.2 Personal Protective Equipment (PPE)
As a minimum, all personnel working on site must wear standard PPE, including:
• Hard hat • Eye protection • Cuff to ankle cover (long trousers and long sleeves) • High visibility vest or garment. • Safety boots
Construction workers will therefore be clearly visible, and will set a consistently high level of PPE and appearance across the site.
Page 29
Construction Traffic Management Plan Turitea Wind Farm TWF-PM-PLN-0012-05_CTMP
7.4 Construction and Temporary Traffic Planning 7.4.1 Construction Pack Planning
Construction of the Project will be divided into a number of construction activities. As part of the planning process, a construction pack will be developed for each activity comprising: . The design plans and specifications applicable to the activities covered by the construction pack; . A Method Statement describing exactly how the work will be undertaken and the hold points for checks, approvals, and records; . A Job Safety and Environmental Analysis (JSEA) documenting the identification, assessment and mitigation of safety and environmental risks associated with the activity; and . Permits required for the respective works, for example: o Approved TMP’s. o Earthworks permits o Discharge permits
The construction pack will then be reviewed and signed off by the appropriate Manager, (or their respective delegates), usually within 24 hours and with changes made as necessary for approval. Temporary traffic management requirements associated with work activities will be included in the construction packs.
7.4.2 Traffic Management Plan
Temporary Traffic Management Plans (TMPs) will be required for all work within the live road corridor, as identified in Section 1.2 TMPs will follow the format set in CoPTTM (Code of Practice for Temporary Traffic Management). They will describe the measures to be implemented to manage the temporary traffic effects associated with temporary road layouts or traffic controls required for specific corridor works.
TMPs will be submitted to, and approved by, the Traffic Management Coordinator responsible for the section of road involved, i.e. by PNCC, TDC & NZTA/Higgins.
The TMPs will be assessed by the Traffic Management Coordinator for compliance with CoPTTM and the ability to avoid adverse effects on the travelling public.
TMPs for the project works will be prepared in accordance with the time period outlined in CoPTTM.
Page 30
Construction Traffic Management Plan Turitea Wind Farm TWF-PM-PLN-0012-05_CTMP
7.5 Implementation
Each day’s work will begin with a Job Start Briefing for each crew, at which point the specific work being undertaken that day will be discussed and documented, including the risks involved and the mitigation measures to be implemented to avoid or mitigate the risks i.e. temporary traffic control measures. Any issues which cannot be solved by the crew will be escalated to the Project Manager as appropriate.

8 Mitigation measures 8.1 Site Access Controls
The site access points for the construction area have been selected to enable construction to proceed safely and efficiently, and with appropriate traffic management controls in place to provide for the safe operation
8.1.1 New intersection of South Range Rd and Pahiatua-Aokautere Road
All the traffic will enter and exit the site through the new intersection. A sign-in box will be installed, set-back from the public road, where every driver will have to stop and sign the Job Briefing to be aware of the daily activity and the vehicle movement plan. Additionally, a site entrance sign will be displayed at the entrance with the relevant information concerning the site and contact persons. The sign-in book will provide the basis for keeping records of the number of vehicles entering and exiting the site. The majority of light vehicles will be arriving to site prior to 7:00am to attend the daily pre- start meeting. Heavy trucks shall be coordinated to arrive outside peak hours. A controlled gate will be located far enough inside the construction site to provide limited parking area for heavy truck & trailer units. All trucks are fitted with radio communication and shall be directed to arrive to site separately i.e. staggered leaving the source.
8.1.2 Pahiatua-Aokautere Road Eastern site access
The eastern site access will be closed and locked except when required to accommodate over-sized blade deliveries. A pre-delivery meeting will be carried out with the transport company and the traffic management personnel to organise these deliveries.
8.1.3 Greens Road Access
The access from Greens Road which was envisaged in the Consent, will not be used by traffic constructing the northern turbine zone.
Page 32
Construction Traffic Management Plan Turitea Wind Farm TWF-PM-PLN-0012-05_CTMP
8.2 Construction Traffic Movements
A large number of construction vehicle movements will be required over the course of the project. Truck movements will be required for the transport of spoil, aggregate, concrete, plant and equipment for the project. Trucks will enter and exit the site as outlined in Section 8.1 above. Some oversize loads may be transported to site outside typical working hours if required, to minimise effects on the public road network. Construction vehicles will use Pahiatua-Aokautere Road to access the project. At peak periods, a total of 100 to 130 staff are expected to be on site at any one time. Staff will travel to site by a combination of single occupant vehicles, while others will carpool with three to four people per vehicle. Assuming an average of two occupants/vehicle, staff will correspond to an additional 130 movements/day during peak times. Project construction yards will have dedicated car parking available for staff. In order to reduce the amount of commuter traffic by construction personnel, the project will encourage carpooling as far as reasonably practicable. For construction to proceed efficiently, the appropriate speed controls need to be in place to provide for the safe transit of construction traffic. A speed limit of 30km/hr maximum will be in implemented throughout the construction works. This covers SRR and the various turbine site access tracks. Additionally, a site-wide policy for the use of strobes/hazard lights shall be implemented.

3 1.0 INTRODUCTION
Mercury proposes to develop a wind farm in and around the Turitea Reserve area, on the Tararua Ranges. The site is South East of Palmerston North City. The site location is in an area where there are presently existing wind farms in operation.
Tranzcarr Heavy Haulage Ltd from Auckland, have been commissioned by Vestas Wind Systems from Melbourne in Australia, to complete the Transport Feasibility Assessment for the site. Vestas are a supplier to Mercury and are proposing to transport Wind Turbine components from the Port of Napier to site. This assessment has focused on the effects associated with transporting the oversized loads; details of which are annexed to this report.
Tranzcarr Heavy Haulage Ltd is an Auckland based heavy haulage operator, working throughout New Zealand and also the South Pacific. Since 2004 Tranzcarr has worked on every major wind farm project in New Zealand, including Te Apiti, White Hills, Tararua, West Wind, Te Uku and Mill Creek; in total, complete transport of some 235 Turbines up to 3.0MW. This includes the longest blades at 49.0m and heaviest towers at 76tonne, and Nacelles at 86tonne, transported to the sites.
Tranzcarr has also developed the only fleet of specialised Ultra Heavy Haulage Prime Movers that allows these loads to be hauled on Wind Farm sites with gradients up to 21percent.
Photo 1 - Tower section West wind Windfarm
Tranzcarr have previously looked at many options for the Turitea site, including deliveries from either New Plymouth or Napier. For the purposes of the present inquiry, the focus is haulage from Napier Port.
4 2.0 ROUTE SELECTION
A site photo, included in Appendix 2, shows the general location of the proposed site, as advised by Vestas Wind Systems, as well as the surrounding road network. Access has been reviewed on the two locations advised and entry is form the eastern side of the Tararua Range via Pahiatua.
The State Highway network within the region that would generally be utilised for the strategic transport requirements of the project, includes SH2 between Napier and Pahiatua.
Appendix 2 is a photo that details the vicinity of the site and access points. The Pahiatua Track Road links east and west (SH 2 to SH 57) across the Tararua Range to the access network for this project. This road is also a very strategic road of importance to the region. Whilst the Manawatu Gorge Road remains closed, (Permanent closure for the foreseeable future); traffic volumes on this road can be very high and some of the corners and gradients identified elsewhere in this report, will prove to be difficult for the heavy and long loads required.
There are three options that could be considered as possible Ports of entry. Wellington is discarded, due to difficulties associated with heavy and high loads exiting of the Port and City, and large traffic volumes. New Plymouth Port was used for the Tararua 3 extension, however for this project the access to the site from the eastern side of the Range, makes Napier the best option. The Napier option is also less kilometres and therefore more efficient to keep up with delivery schedules and cost for transport.
The approved route for the heavier loads, has been assessed by the following agencies:
• New Zealand Transport Agency • Napier City Council • Tararua District Council • Kiwi Rail for level line crossings
A more detailed study of the route identifying areas of concern, follows elsewhere in this report. .
2.1 New Zealand Transport Agency (NZTA)
All over dimension and overweight loads hauled on the road network, are controlled by permits issued by NZTA.
For this report Tranzcarr applied for approval to haul the heaviest load being part of the Nacelle from the Port of Napier to the site entrance off the Pahiatua Track Road, adjacent to North Ridge Road. A copy of the feasibility permit issued No: NP/S/18/0842 is annexed in this report.
This is not a final permit, but does cover the route and provide details on the bridge structures that will need to be crossed and the conditions of travel imposed. Tranzcarr considered the different route options detailed with NZTA and the local councils for the heavy loads on this project.
5 2.2 Tararua District Council
The main State Highway network, travels through the city of Napier and South via Woodville to Pahiatua. The road East from Pahiatua and over the Pahiatua Saddle Road, is controlled and managed by the Tararua District Council. They have reviewed the information approved by NZTA in their route feasibility assessment and a copy of the council permit is included in this report.
Travel time restrictions for the local area are set out in the Land Transport Vehicle Dimension and Mass Rule 41001 and its amendments.
Section C3.3 Travel time and zone restrictions of the above Rule from NZ Transport Agency Permitting Manual (2nd edition).
Prohibited Travel time for loads up to and including 5metres wide
Travel is not allowed, at the following times:
Monday to Thursday 0630 - 900am 1600-1800pm Friday 0630 - 900am 1600-2400pm Saturday 0.00 – 0500am 1200-2400pm Sunday 0.00 – 0500am 1200-2230pm
The travel restriction time between 6.30 and 9.00 hours and 16.00 and 18.00 hours, apply to City areas only. For this project, these restrictions only apply to Napier City.
The long blade loads would be better suited to be hauled through Napier to the southern boundary and clear prior to 0630am, to avoid the restrictions above, and also the traffic issues with such a long load being hauled through the City limit.
2.3 Kiwi Rail
There are a number of level rail crossings on the route; a permit approval will need to be issued by Kiwi Rail to allow travel. It is not expected there will be any difficulties in obtaining the approval necessary to move. All large over-dimensional and heavy loads need to be recorded into Kiwi Rail, prior to crossing any level track intersection.
The bypass at Ahuriri in Napier is also owned by Kiwirail and co-ordination for all loads will be a requirement.
6 2.4 Route ex Port of Napier to site.
The route off the Port and also covering the proposed storage off the Port, is detailed in the following section, 3.0 of this report. The route via the State Highway network is identified here.
From our assessment, the following route has been identified as the most practical and appropriate and provides the best transportation outcome for the project, taking in to account the size of the loads and other road users.
• Port via Breakwater Road to Ahuriri Bypass • Use of over-dimensional bypass at Ahuriri “peanut” roundabout, see Photo 2 • Bridge Street to Hydrabad Road • Prebensen Drive from Hydrabad Road to SH 50. • Napier-Hastings Expressway via SH50A and SH 50 south to SH2. • SH 2 south to Pahiatua with exception of bypass routes:
i. Peel Street and The Esplanade (heavy traffic bypass) in Waipukurau. ii. Norsewood bypass to avoid over-bridge. iii. Tay Street to Station Street (heavy traffic bypass) in Woodville.
• Pahiatua Mangahao Road to Makomako Road, Pahiatua Aokatere Road to site entrances.
7 2.4.1 Ahuriri Bypass.
This bypass was installed for the Te Apiti Windfarm Project and is available for use. Coordination with Kiwi Rail is required to gain access on a daily basis and operators need to work in with Train Shunt movements on and off the Port area.

8 2.4.2 Hydrabad Road-Prebensen Drive
2.4.3 Prebensen Drive – Sivern Street
Photo 6 and 7 – Prebensen/Sivern roundabout, no problems with this route
This route will also be the exit route from the Thames Street storage yard, should this be used as a possible storage area off the Port. This is a large wide road; possible removal of road signs only for long loads to pass through.
9 2.4.4 Prebensen Drive to SH 2B
Photo 8 – SH 2B intersection
Left turn from Prebensen Drive onto SH 2B South will need to be widened for the long Blade loads. Guard rails on the inside corner with a light Pole (seen in Photo 8), restricts turning circle. The grass area shown in above photo could be sealed to allow a greater turning circle to potentially avoid removal of light Pole and guard rail.
2.4.5 SH 2B-SH 50
This section of the highway network has a number of traffic roundabouts at the following intersections:
• Taradale Road • Pakowhai Road • Evenden Road • Omahu Road • Flaxmere Road • Longlands Road.
With the exception of the last roundabout at Longlands Road, all the other crossings appear to be suitable for the long loads. Some road furniture and street lights will need to be removed to avoid any collisions. At Pakowhai Road, major road modifications are presently underway.
10 Photo 9 – Longlands Roundabout
The roundabout at Longlands Road, has a very sharp left turn and the long loads will not negotiate this. Light poles and signage will also restrict access. The alternative is to cross over to the wrong side, heading South and use this lane to negotiate the roundabout.
The aerial photo below from Google, shows the sharp left turn heading South on SH 50A. Crossing over makes it easier for the long loads. This can be managed by the load escort pilots with the load.
Photo 10 – Aerial photo of Longlands Road roundabout with arrows indicating wrong side access for long loads
11 2.4.6 SH 50A to SH 2 south
This intersection also has a large roundabout, and this will require some attention for the long loads to negotiate.

12 Photo 13 – view heading south from SH50A and SH 2 roundabout (note signage and light pole on inside corner)
2.4.7 SH 2 Waipakurau
The SH 2 Highway passes through the Central Hawkes Bay town of Waipakurau. All heavy traffic is required to use the local road bypass, to avoid the main town centre. At the time of this report, the bypass road was closed with major remedial works.
The roads used to bypass SH 2 are Peel Street and The Esplanade, when driving South from Napier. These are wide arterial roads, however the inside left corner with light pole, shown in the photo below, will need to be clear to allow the long loads to pass.
Photo 14 – Peel St bypass Waipakurau, view heading south, note light pole.
13 2.4.8 SH 2 – Norsewood bypass
There is an over-bridge on SH 2 linking the Township of Norsewood. This is a significant obstacle of SH 2 in both directions and affects all OD loads. The bridge has a clearance of 4.80 metres but does have a bypass, as shown in the photographs below.
Photo 15 and 16 – Norsewood bypass south and fence that can be removed at top of bypass to allow access back onto SH 2 once passed the over-bridge
2.4.9 SH 2 – Woodville
The SH 2 Highway passes through the township of Woodville and then South to Pahiatua. There is a heavy traffic bypass to avoid the main shopping area of the town.
The bypass to SH 2 - Tay Street, Station Road and back onto SH 2 south.
Photos 17 and 18 – Left turn off SH 2 into Tay Street, Woodville. Some widening of the grass verger area may to required to allow access for long loads. Street signs can be removed

Photos 21 and 22 – Left turn from Station Road back onto SH 2, note street light on outside of the corners that will need removing for long loads. Street signs that will need removal
2.4.10 Pahiatua Township
From Woodville, SH 2continues South to the township of Pahiatua. There are no problems with the road network until the right turn in the centre of the township, onto Pahiatua Mangahao Road. See photos 23 and 24 - this intersection will require reshaping, to allow the long loads to access and turn right.
15 Photo 23 – right turn off SH 2 onto Pahiatua Mangahao Road. Note Islands, street signs and trees
Photo 24 – another view of right turn off SH 2 to Pahiatua Mangahao Road
At this intersection, the centre islands will need to be modified to allow the long loads to pass through; some trees and street signs will also need to be removed.

21 3.0 PORT FACILITIES
The Port of Napier is the best option for receiving all the equipment for the project. The alternatives of Wellington and New Plymouth have more restrictions in terms of large over-dimensional loads being handled.
Napier has previously handled Wind Farm equipment for the Te Apiti and Tararua 1 projects. The Port is a major hub for export of timber and seasonal fruit, and has limited space for large quantities of specialised over-dimensional freight. The Port can supply additional storage away from the main Port location, and whist this is not the best scenario, it may be the best option for consideration.
Two storage yards in Thames Street, approx. 4.3km from the main Port area, can be made available by the Port for the project. Access to these yards is restrictive and the long blade loads would be best remaining on the Port area proper, whilst other loads such as Towers, Hubs and Nacelles could be stored in these areas. Additional transport will be required to assist the ships discharge and handling of the cargo to be stored off the Port area.
Photo 42 and 43 - showing access to Port Storage facilities on Thames Street
Restrictions negotiating both the roundabouts at Hydrabad Road and the turn into Thames Street, off Pandora Road, will mean long blade loads should remain within the Port area.
There is an alternative that can be used via Prebensen Drive, Severn Street and Thames Street, to avoid the roundabout at Hydrabad/Pandora. There are two further roundabouts on Prebensen Drive to negotiate access to be considered.
In summary, provided the blade units can remain on the Port for storage, any or all of the other components could be stored in the Thames Street sites.

23 4.0 OVERHEAD POWER COMPANIES
The standard height for all loads on the highway network in New Zealand, is 4.25metres off the ground. Loads that exceed this height, will require an approval from the local lines companies to ensure they have clearance.
A number of the loads detailed in this project, will exceed the 4.25metres when loaded for travel and therefore will require a permit approval.
There are a number of local lines companies namely:
Unison Networks Ltd Scan Power Ltd Central Lines Ltd Powerco Ltd Chorus Network
These companies generally allow loads up to 5.4metres in height, to travel with a permit and without the need for an additional escort to supervise the clearance under the wires, across the network. The tower sections are all over-height and could be subject to an escort from the Lines Companies, depending on the trailer configuration used. There will be costs associated with these services provided. Discussions prior to the project commencing, could assist with the network being reviewed and wire heights checked, and potentially raised prior to haulage starting. Need to approach power companies and allow for assistance to overdimension loads; 1st time for tower sections then allow to elevate wires at road crossings 5.0 CONCLUSIONS
This report makes the following conclusions:
• All loads can be hauled from the Port of Napier to site at Turitea. • The Port at Napier has capacity and space to handle the proposed cargo loads for the project; this includes some offsite storage facilities. • The approved route for the heavy loads, is as detailed in the feasibility permit issued by NZTA and supported by the local councils. • There is a need to have temporary works done on the route, to remove road furniture and traffic signals. • All overhead Lines Companies will need to be involved in the consultation process, to gain approval for all high loads over the complete route. • A simulated drive over the route by a trailer, proposed for the Blade transport, is recommended in conjunction with the Suppliers to review and identify correctly the problem areas. Details mapping of the long loads on the affected corners and roads will also be required.
