3.2 Non-Material Amendment

During the development of detailed designs for the construction of the wind farm it became

apparent that improvements could be made through small changes in the layout of

infrastructure, to help minimise the quantities of earthworks required and improve health and

safety during construction. A Non-Material Amendment (NMA) was thus applied for and

approved in February 2013, refer to Annex 1 for details of the approval and description of

changes to the design incorporated in the NMA.

3.3 Design Basis

RES has employed a mix of internal specialists and external consultants to develop and

validate an appropriate design associated with the site specific conditions for Woolley Hill

Wind Farm.

The following parties were used in the preparation of this method statement:

McCloy Consulting (Drainage design)

Waterman Transport & Development Ltd (Site Access and Bridge design)

Mott MacDonald (Substation design)

RSK Environment Ltd (Geotechnical Investigations)

4.0 CONSTRUCTION PHILOSOPHY AND GENERAL WORKS

Woolley Hill Wind Farm will be constructed in accordance with the Environmental Statement

2010, the Supplementary Environmental Information 2011 and the Non-material Amendment

2013 prepared during the development stage of the project.

Throughout the development of project, the overarching design philosophy has been to ensure

the design:

minimises extent of infrastructure;

avoids sensitive habitats;

minimises environmental impacts; and

maximises health and safety.

Where appropriate and practicable, local plant and materials will be used in order to

maximise the benefit of the wind farm project to the local community.

4.1 Timescale

4.1.1 Wind Farm Operation

In accordance with Planning Condition 1, the development will commence before the

expiration of 5 years from the date of the consent.

In accordance with Planning Condition 3, the permission for the operation of the Wind Farm is

for a period not exceeding 25 years from the date when electrical power is first exported from

any of the wind turbines to the electricity grid network, excluding electricity exported during

initial testing and commissioning.

In accordance with Planning Condition 4, within 24 months of the end of the period of

consent pursuant to Planning Condition 3, those parts of the Development requiring

decommissioning and restoration in accordance with the conditions of the consent will be

removed and the land restored, in accordance with the decommissioning of the scheme and

detailed restoration and aftercare required by Planning Condition 4.

In accordance with Planning Condition 5, if an installed and commissioned turbine fails to

produce electricity for supply to the grid for a continuous period of 6 months, a scheme will be

submitted to Huntingdonshire District Council for its written approval within 3 months of the

end of that 6 month period for the repair or removal of the relevant turbine.

4.1.2 Wind Farm Construction Hours

In accordance with Planning Condition 6, construction work will only take place between the

hours of 07:00 19:00 on Monday to Friday inclusive and 08:00 13:00 hours on

Saturdays. No construction work will take place on a Sunday or Public Holiday. Outside these

hours, works at the site will be limited to emergency works and dust suppression. The Local

Planning Authority will be informed in writing of emergency works within 3 working days of

occurrence. Where turbine erection has started, emergency work includes any construction

work necessary to make the turbine safe.

In accordance with Planning Condition 7, the delivery of any construction materials or

equipment for the construction of the development, other than turbine blades, nacelles and

4.2 Environmental Management

Monitoring will be carried out throughout the construction of the wind farm. Specific

documents relating to this are:

1. Environmental Requirements of Contractors Annex 3

2. Emergency Procedure in the Event of a Contaminant Spill Annex 4

3. SuDS Design Statement Annex 5

4. Water Quality Monitoring Procedure Annex 6

4.2.1 Contractors Requirements

Specific details of the environmental management and emergency procedures to be adopted

during the construction phase by Contractors are detailed in the Environmental Requirements

of Contractors document.

RES specific environmental management requirements and compliance of the Contractors to

their environmental responsibilities are managed through our Environmental Management

System Procedures and Policies which are certified to ISO 14001.

The appointed Contractors will be required to adopt methods of working on site which reduce

the effects of noise occurring during the construction period in accordance with BS 5228:

Noise control on construction and open sites. The following mitigation measures will be

implemented where necessary:

For any particular job where construction noise may be an issue, the quietest plant

and/or machinery will be used where reasonably practical;

All equipment will be maintained in good working order and fitted with the

appropriate silencers, mufflers or acoustic covers where applicable;


p.8

Stationary noise sources will be sited as far away as reasonably possible from

residential properties and where necessary acoustic barriers will be used to shield

them; and

The movement of vehicles to and from the site will be controlled and employees

supervised to ensure compliance with the noise control measures adopted.

The appointed Contractors will be required to sheet all heavy goods vehicles when

transporting loose construction materials to, or spoil from the site, to prevent spillage or

deposit of any materials on the highway.

4.2.2 Management of Surface and Ground Water and Water Quality Monitoring

Any incident that may impact on water quality will be dealt with in accordance with the

Emergency Procedure in the Event of a Contaminant Spill.

Detailed measures to address surface water management during the construction of the wind

farm will be based upon the SuDS Design Statement prepared by McCloy Consulting.

Water quality monitoring in accordance with the Water Quality Monitoring Procedure will be

undertaken on discharge waters prior to, during and following the construction phase to assess

and manage the performance of the drainage system, making adjustments as necessary to

ensure that site drainage does not impact on local watercourses.

4.2.3 Temporary Lighting

Temporary lighting will be required at the temporary construction compounds for security

purposes and to ensure that a safe working environment is provided to construction staff. In

addition, temporary lighting may be required to ensure safe working conditions during

construction. Any works will be undertaken within the working hours defined by Planning

Condition 6 of the planning permission, unless otherwise agreed with the Planning Authority.

All lighting rigs will be downward facing and all lights will be switched off during daylight

hours.

4.2.4 Dust Management

Typical construction operations such as the excavation and deposition of materials, vehicle

movements around site and site cutting works may result in dust arising during the works. The

potential issue of dust creation during the works will be weather and season dependant,

therefore detailed dust management methods will be subject to the works programme and

contractor working methods.

Dust management will be carried out at all times in accordance with industry best practice

measures to ensure that any local sensitive receptors are not affected by nuisance levels of

dust from the works. The following methods of dust suppression will be implemented during

the construction phase of the wind farm:

Site tracks to be damped down using bowser or other suitable system;

Road sweeper to be used to remove loose material from highways during construction;

Cleaning vehicles including wheel washing facilities;

Soil erosion control measures;

Speed limits to be put in place to ensure low vehicle speeds;

Vehicle loads to be covered;

Damping of dry excavations and cutting activities which generate dust; and


p.9

Programming of works to minimise the time that soils are exposed.

4.3 Flood Risk Assessment

Planning Condition 30 states that the development shall only be carried out in accordance

with the approved Flood Risk Assessment (FRA) (February 2011) submitted in Appendix 3.1 of

the Supplementary Environmental Information.

Mitigation measures outlined in the FRA have been incorporated in the design of the new

bridge, access tracks, drainage and other site infrastructure and the positioning of temporary

and permanent buildings on site. The following consents will be obtained from the relevant

drainage authority (Environment Agency and Alconbury and Ellington Internal Drainage Board

(IDB)) to satisfy compliance with Planning Condition 30:

Environment Agency

Flood Defence Consents (separate consents for both the Permanent and Temporary works):

Construction of the new bridge across Ellington Brook; and

Construction of access tracks, associated extension of drainage pipe and connection of

new drainage to existing outfall within 9m of the top of bank for Ellington Brook.

Alconbury and Ellington IDB

Application for Consent for Works Affecting Watercourses:

Works affecting tributaries of an IDB controlled watercourse; and

Extension of drainage pipe.

4.4 Site Won Materials

Analysis of geotechnical site investigation results has determined that material won from the

lower strata is unsuitable for construction use within the development. Therefore all stone for

tracks, compounds, sub-station and crane hardstandings will be imported from appropriate

local sources, where possible.

Soil mixing, strengthening and compacting may occur with materials available in the upper soil

strata on site and will be performed in-situ to the extent possible. Suitable material at

locations specific to excavations such as turbine foundations, crane hard standings and

building platforms may be excavated and treated such that they are suitable as engineering

fill within the site.

4.5 Spoil Management

In line with construction best practice and to suit the ground conditions anticipated on site,

the track and crane hardstanding design has endeavoured to minimise spoil created during

construction.

Topsoil and spoil excavated during the works will generally be stockpiled close to the

excavation to limit vehicle movements on site. There will be no permanent storage of

excavated materials within a 10m buffer of any watercourse, stream or river on site to

prevent possible wash-out of fine soils or risk of instability of the watercourse banks. There

will be no permanent spoil stockpiled within the floodplain as identified in the Environment

Agencys flood mapping. The locations for the permanent placement of excavated spoil are

shown on Drawing 02341D3503-01 in Annex 2.


p.10

4.6 Traffic Management

In accordance with Planning Condition 30(t), details of the proposed traffic management for

the site have been developed and are included in the Woolley Hill Wind Farm Traffic

Management Plan (TMP) (Reference: 02341-004519).

4.7 Reinstatement of Construction Areas

4.7.1 General

Reinstatement will be undertaken as work progresses using the turf and or topsoil removed

during the construction activities detailed in Section 5.

In addition, following the completion of the works a final inspection of the wind farm site will

be undertaken and in circumstances where reinstatement using turf and or topsoil is

unsuccessful alternative methods will be considered.

4.7.2 Temporary Construction Compounds

The temporary construction compounds will be reinstated to the approximate pre-construction

condition and the following shall take place:

all temporary structures, construction equipment and fencing will be removed;

the granular material which was placed to form the hardstanding areas will be taken

up and removed to areas agreed with the landowner; and

the areas will be backfilled with material stripped and stored during the construction

of the compounds, covered with topsoil and reseeded as required.

4.8 Community Liaison

Throughout the construction period of the project, RES will maintain an open dialogue with

local residents and all other interested parties. Regular progress meetings will be held within

the local communities and updates on progress and forthcoming activities will be

communicated by a dedicated website and regular newsletters.

A dedicated Community Liaison Officer will be appointed to provide a key contact between

RES and the community through a Community Liaison Group (CLG). Details of this CLG are

provided in Annex 7.

4.9 Health and Safety Management

The Principal Contractor will be responsible for ensuring that a construction phase health and

safety plan is implemented and followed on site. All work will be carried out in accordance

with:

the Health and Safety at Work etc. Act 1974;

the Construction (Design and Management) Regulations 2007; and

all applicable third party safety guidelines.


p.11

5.0 CONSTRUCTION METHOD

5.1 Temporary Construction Compounds and Site Fencing

5.1.1 General

Temporary construction compounds are required for the provision of site offices, welfare

facilities and storage arrangements for materials, plant and equipment. There are two

temporary construction compounds required for different areas and stages of the project.

The temporary construction compounds will be constructed at the locations indicated on

Drawing 02341D1001-06 in Annex 2. Details of the construction compounds are shown on

Drawings 02341D2220-02, 02341D2239-02 and 02341D2229-02 in Annex 2.

The Main Construction Compound shown in Drawing 02341D2220-02 and 02341D2239-02 in

Annex 2 will be built for use during construction of the access tracks and as the main

compound for the site, with welfare facilities provided at this location.

The Enabling Works Construction Compound shown in Drawing 02341D2229-02 in Annex 2 will

be used solely for the temporary setting down of materials during the construction of the

Ellington Brook Bridge. As the compound is located within the floodplain identified within the

EA flood mapping, it will not be fenced and no temporary construction buildings will be

erected.

5.1.2 General Construction Method

The typical construction activities associated with the temporary construction compounds are:

the areas to be used as compounds will be set out;

topsoil shall be removed and carefully stockpiled;

granular material will be spread and compacted to provide an area suitable for the

siting of offices, storage containers, parking (where required) and to enable offloading

of materials;

a covered, impermeable bunded area will be provided within the Main Construction

Compound for the storage of fuel oils. Refuelling will be undertaken in line with the

requirements as outlined in Annex 4;

the Main Construction Compound will be fenced around the perimeter and secured

with locked gates outside working hours.

5.2 Site Entrances

5.2.1 General Method

All traffic associated with construction of the wind farm (except for some larger turbine

components) will be required to access the site via Grove Lane using the newly constructed

General Site Entrance in accordance with the TMP. Grove Lane is a Cambridgeshire County

Council (CCC) adopted highway, therefore technical approval for the new entrance will be

sought from CCC.

Turbine component deliveries will be made via both the newly constructed General Site

Entrance and the Abnormal Load Site Entrance from the eastbound off-slip at Junction 20 of

the A14. The A14 off-slip is a Highways Agency (HA) adopted highway, therefore technical

approval for the new entrance will be sought from the HA.


p.12

The site entrances will be constructed at the locations indicated on Drawing 02341D1001-06 in

Annex 2. Details of the site entrances are provided in the Woolley Hill Wind Farm Traffic

Management Plan (TMP) (Reference: 02341-004519).

All works to be carried out within the public highway will be designed in accordance with the

relevant Highway Authoritys standards. Technical approval for the works will be obtained

from the relevant Highway Authority prior to the works commencing. The technical approval

will address:

construction of the access into the site;

erection of entrance gates;

creation of visibility splays;

installation of a removable barrier for restricting access to the new bridge (Abnormal

Loads Site Entrance only); and

cleaning of site entrances, facilities for wheel washing and cleaning the adjacent

public highway.

Prior to public road works being undertaken, a Section 278 Agreement in accordance with the

Highways Act 1980 will be entered into with the relevant Highway Authorities. All works to

public roads will be carried out in accordance with details of the Section 278 Agreement. A

detailed programme of all works and any required traffic management proposals will be

submitted to and agreed with the Highway Authorities

5.2.2 General Construction Methodology

The site entrances will be constructed in accordance with the approved technical drawings as

follows:

obtain necessary permits and approvals from Cambridge County Council, Highways

Agency and the Environment Agency;

inform statutory services & identify any assets to be protected or diverted;

install appropriate traffic management;

topsoil shall be removed and carefully stockpiled;

new drainage will be installed taking care to ensure that existing drainage will not be

compromised;

edge restraints where required in the design will be installed;

road pavement works at the site entrance will be completed to the design

requirements of the relevant Highway Authority; and

line marking, signage, fencing and vehicle restraint systems required as part of the

design will be completed.

5.3 Site Tracks

5.3.1 Design Philosophy

The general approach to road construction is to provide an alignment that minimises

environmental impact whilst providing an access track that meets the requirements for the

safe delivery of wind turbine components and other vehicles.

The running width of the tracks shall be in accordance with the requirements of the chosen

turbine supplier. Typically this is 4.5 - 5.5 metres wide on straight sections, increasing at

corners and passing places to accommodate the swept path of turbine delivery vehicles. The


p.13

track working area will be kept to the minimum required allowing for working area, safe

access, drainage and electrical works.

All site tracks have been designed taking account of the loadings provided by the turbine

manufacturer, and will consist of compacted stone structure. A number of track designs may

be utilised on site which will be determined during detailed design dependent on the ground

conditions encountered on site. Examples of the track designs that may be used can be found

in Drawing 02341D2221-02 in Annex 2 and include:

cut track from suitable load bearing strata;

cut track from ground improved strata;

floating track; and

another appropriate method identified by the civil works contractor appointed to

undertake the works.

Track drainage will be incorporated within the design as set out in Drawings MCL115-

54_DWG_101_5 to MCL115-54_DWG_105_5 in Annex 5.

5.3.2 Cut Track

Cut track construction may be used in areas identified where the thickness of soft soils is low,

and the underlying layer has adequate load bearing properties. This cut track system will

likely consist of a suitable capping layer and then a suitable running layer, but may be

optimised if a stiffer bearing stratum is encountered.

5.3.3 Floating Track

Floating track construction may be adopted where the ground conditions require. This system

involves installing geo-grid directly onto the organic or exposed soil layer and placing layers of

suitable stone and geo-grid (as required) above.

5.3.4 Ground Stabilisation

Where the load bearing properties of the underlying soils are determined to be insufficient,

ground stabilisation may be carried out to provide adequate bearing capacity of the formation

level. A variety of methods may be required due to the variable nature of the ground at

Woolley Hill but are likely to comprise in-situ soil mixing with lime and/or cement. Specific

construction methods shall be selected at detailed design stage in consultation with specialist

contractors. Any track design based on ground improvement techniques will be performed in

accordance with a project specific Specification for Ground Improvement Works.

5.3.5 Watercourse buffers

A buffer zone will be maintained around all watercourses on site. The exception to these

buffer zones is where there are crossing points or where the existing track is located within

the buffer zone. Site personnel will be made aware of the buffer zones through the site

induction and specific tool box talks. Buffer zones and mitigation measures to prevent

contamination of watercourse by silts will be in accordance with the SuDS Design Statement

provided by McCloy Consulting in Annex 5.

5.3.6 General Construction Methodology

The following general methodology will apply to construction operations for both upgraded

tracks and new tracks:


p.14

establish alignment of the site tracks from the construction drawings and mark out the

centrelines with ranging rods or timber posts, track corridors shall be pegged out in

advance of operations;

a cut off ditch may be installed on the slope above the earthworks footprint where

achievable given the sloping topography;

topsoil will be removed and stored carefully for use in reinstatement works (not

applicable to floated tracks);

any remaining subsoil will be excavated down to a suitable bearing stratum and set

aside along each side of the road, for later use in landscaping, backfilling around

structures and verge reinstatement (not applicable for floated tracks);

design buffer zones will be adhered to and as construction is progressed the

effectiveness of the buffer zones will be reviewed and if necessary increased;

depending on depth and type of material, embankment slopes are anticipated to be

between 1:1 to 1:3;

the stone track pavement material shall then be either spread by a dozer or placed by

excavator and compacted in layers, typically using vibratory rollers. The thickness of

layers and amount of compaction required will be determined based on the design,

which will take account of the characteristics of the material and the compaction

plant to be used;

track drainage will be excavated adjacent to the tracks where required. The running

surfaces of the site tracks will be finished to encourage drainage and reduce ponding.

Surface water runoff will not be allowed to discharge directly into existing

watercourses but will be routed through the drainage system;

where the road alignment crosses existing drainage channels, crossings appropriate to

the location will be designed in accordance with the relevant guidelines; and

reinstatement of the road verges, drainage swales and embankments will be ongoing

as the roads are constructed. The intention will be to minimise the amount of time in

which any material will be stockpiled.

5.4 Bridge

A bridge across Ellington Brook is required to provide access to the site for the delivery of

turbine components. The construction of the bridge will require permanent Flood Defence

Consent from the Environment Agency under the Flood and Water Management Act.

The Abnormal Load Access Bridge General Arrangement is shown on Drawing

CIV_SA_03_100_A03 in Annex 2.The proposed bridge will be a single span bridge so that there

is no support within the existing channel and will have an overall length of approximately 10.5

metres between faces of abutments. The bridge deck will be supported on reinforced concrete

abutments and have steel containment parapets.

5.4.1 Method Statement

A Flood Defence Consent for temporary works will be obtained from the Environment Agency,

prior to the works commencing. The temporary works Flood Defence Consent will include a

method statement developed with reference to Works and maintenance in or near water:

PPG5 and will details how elements of the bridge will be built including addressing the

following:

excavation for abutments and managing the risk of silt pollution;

disposal of contaminated water;

managing concrete and cement used in the works; and


p.15

use of oils and chemicals in the works.

5.5 Crane Hardstandings


All crane hardstandings will be designed taking account of the loadings provided by turbine

manufacturers, and will consist of one or a combination of the following:

a compacted stone structure bearing directly on a suitable formation strata;

a compacted stone structure bearing on a formation strata improved through ground

stabilisation techniques;

a compacted stone structure bearing on a strengthened soil mass created by the

installation of multiple stone or concrete columns; or

another appropriate method identified by the civil works contractor appointed to

undertake the works.

Floated construction is not deemed to be acceptable for crane hardstandings due to the

flexibility of such structures and the inevitable settlement.


The main crane hardstandings are anticipated to be 40m x 30m and have a maximum cross and

longitudinal fall tolerance of 1% (1:100). The temporary hardstanding elements as shown in

Drawing 02341D2226-04 in Annex 2 will be reinstated post construction. The main crane

hardstanding area will be left uncovered for the operational lifetime of the wind farm in line

with good practice outlined in the Scottish National Heritage guidance Good Practice during

Windfarm Construction.

Where competent soils exist close to the existing ground surface, the hardstanding area shall

typically be constructed using the following methods:

a cut off ditch may be installed on the slope above the earthworks footprint where

required given the sloping topography;

topsoil will be removed and stored carefully for use in reinstatement works;

any remaining subsoil will be excavated down to a suitable bearing stratum and set

aside for later use in landscaping, backfilling around structures and verge

reinstatement;

where excavation is required to extend below the water table or in material which

does not drain freely, appropriate pumping will be employed to keep the excavation

dry. Water pumped from an excavation shall not be discharged directly to any

watercourse, and shall be treated according to the principles of the SuDS Design

Statement, refer Annex 5.

temporary & permanent drainage shall be installed;

temporary and permanent drainage will be excavated adjacent to the crane

hardstanding where required. The surfaces of the crane hardstanding will be finished

to a cross fall of no greater than 1% to encourage drainage and reduce ponding.

Surface water runoff will not be allowed to discharge directly into existing

watercourses but will be routed through the drainage system;

the crane hardstanding material shall then be either spread by a dozer or placed by

excavator and compacted in layers, typically using vibratory rollers. The thickness of

layers and amount of compaction required will be determined based on the design,


p.16

which will take account of the characteristics of the material and the compaction

plant to be used.

Where the load bearing properties of the underlying soils are determined to be insufficient,

ground stabilisation may be carried out to provide adequate bearing capacity of the formation

level. Due to the variable nature of the ground at Woolley Hill Wind Farm, specific

construction methods shall be selected at detailed design stage in consultation with specialist

contractors. Such methods may consist of:

Compaction of the existing in situ soils;

Lime/cement stabilisation of the existing in situ soils; or

Installation of stone or concrete columns to provide adequate support.

Any crane hardstanding design based on ground improvement techniques will be performed in

accordance with a project specific Specification for Ground Improvement Works.

In all cases, the completed hardstanding platform shall consist of a compacted stone layer

from the improved formation level to design level.

5.6 Turbine Foundations


Foundations will be designed in accordance with the RES Basis of Design - Wind Turbine

Gravity Base Foundations, taking account of the specific foundation techniques to be

employed at Woolley Hill. Due account will be taken of guidance provided in appropriate

codes and standards such as Eurocodes, British Standards and other specialist design

documents.

Due to the anticipated load bearing capacity of the near surface soils, gravity base turbine

foundations are expected to be used to support the wind turbine superstructure. The wind

turbine foundation is characterised by having to resist very high overturning moments. Gravity

foundations are designed to have sufficient weight to maintain stability under all loading

conditions and be of appropriate size and stiffness to distribute load in accordance with the

geotechnical conditions encountered at each turbine location.

The foundations will be designed as a reinforced concrete structural slab. The foundation

geotechnical design will be based on the information contained in the site investigation

reports produced by RSK Environment Ltd and factors of safety will be incorporated in

accordance with European design standards. The site specific designs will typically be of the

dimensions detailed on Drawing 02341D2225-02 in Annex 2.

An earth mat will be buried around the turbine to provide protection to personnel in the event

of an electrical fault during operation of the wind farm.

The foundations will been designed and constructed in accordance with relevant UK safety

legislation and design regulations. Design risk assessments will be carried out and risk

mitigation measures incorporated into the design.

5.6.2 General Construction Method

Details of the foundation works are detailed in the sections below:

the extent of the excavation will be marked out, including an allowance for trimming

the sides of the excavation to provide a safe working area;

the topsoil will be excavated and stored to one side for reuse during the landscaping

around the finished turbine;


p.17

where excavation is required to extend below the water table or in material which

does not drain freely, appropriate pumping will be employed to keep the excavation

dry. Water pumped from an excavation shall not be discharged directly to any

watercourse, and shall be treated according to the principles of the SuDS Design

Statement, refer Annex 5.

temporary & permanent drainage shall be installed;

excavation will be undertaken to competent material. Excavated material may be

stockpiled temporarily adjacent to the excavation for later use as backfill or stored

elsewhere on site;

a layer of concrete blinding will be laid directly on top of the newly exposed

formation, finished to ensure a flat and level working surface;

steel reinforcement, the turbine anchorage system and cable ducts will be fixed in

accordance with the designers drawings and schedules. Formwork will be erected

around the steel cage;

concrete will be placed using a crane, pump or other suitable lifting device and

compacted using vibrating pokers to the levels and profile indicated on the drawings

and in accordance with best working practices;

upon completion of the concreting works the foundation will be covered and allowed

to cure;

following the curing period any formwork around the foundation will be stripped and

stored for reuse;

the foundation will be backfilled with suitable material, where possible using the

material arising during the excavation, and landscaped using the vegetated soil layer

set aside during the initial excavation;

a gravel footpath will be built leading from the access track or crane hardstanding to

the turbine door or access steps and around the turbine for maintenance.

In the case where competent material is lower than the required formation level the

foundation will likely be over-excavated to competent material and compacted engineering

fill used to provide suitable bearing capacity.

5.7 Turbine and Turbine Transformer Erection

5.7.1 Turbines

In reference to Planning Condition 8, Planning Condition 9 and Planning Condition 10, the

turbine will be supplied with a semi matt finish and be pale grey colour (RAL 7035) and

installed with a height not exceeding 130.5 m measured from ground levels to the blade tip in

the vertical position. The wind turbine blades will rotate in the same direction.

The turbines will not carry any symbols, logos or other lettering except where required under

other legislation. However, RES propose to add turbine numbers to the base of each tower to

aid service engineers during the operational phase of the wind farm. A typical detail for a

completed turbine is shown in Drawing 02341D2227-02 in Annex 2.

In line with health and safety best practice, turbine manufacturers have indicated a

preference to locate a passive infra-red (PIR) detector and light above each turbine door. It

should be noted that this lamp will not be permanently lit and would only be switched by the

PIR when personnel approach a particular turbine.

Specific locations for the turbines are as per Drawing 02341D0001-09 in Annex 2.


p.18

5.7.2 Turbine Transformers

Depending on the model of turbine finally chosen for the site, turbine transformers will be

placed externally to the main turbine.

The transformers are delivered by the manufacturer. If the oil cooled type, they will be

supplied full of oil and will not require topping up or filtering on site. The transformers will be

of the sealed type and will be inspected for any damage prior to offloading.

The units will be tested, commissioned and energised by suitably trained and authorised

persons. The transformers will be located within enclosures which shall be locked, accessible

by trained and authorised personnel only, and displaying appropriate warning signs.

5.7.3 General Turbine Erection Method

The following steps will be undertaken in order to erect the turbines on site:

turbine components are delivered in sections to the site;

the sections are lifted by adequately sized cranes (1 main crane and smaller tail

crane) and positioned on the foundations / other turbine sections until the entire

turbine is erected;

wind turbine erection is subject to a maximum wind speed and for safety and

structural reasons if the upper tower section is in place it must have the nacelle

section in place too, or other means to ensure the structural integrity of the tower in

its partly constructed state;

upon completion of the erection all fasteners will be tightened to the correct torque

and the internal fit out of the turbine undertaken. Finally the mains power will be

connected to the turbine controller; and

when the controller is booted up the turbine commissioning will commence, and

following the successful execution of the tests on completion the turbines will be

handed over as complete.

5.8 Cable Trenching Works


In accordance with Planning Condition 13, all electricity and other service cables between

the turbines and the substation/control building will be placed underground.

The detailed construction and trenching specifications will depend on the ground conditions

encountered but typically cables will be directly buried inside a trench, except at road

crossings where cables will be ducted.


The approximate layout of onsite cables can be found in Drawing 02341D4301-01 in Annex 2.

The cable trench cross sectional size is dependent on the number and size of the cables

required at each location. Typical details of a cable trench are shown in Drawing 02341D4304-

02 in Annex 2.

The following construction method will typically be used when cable trenching is on flat

terrain:

trenches will be excavated and a suitable bedding material placed for which to lay the

cables upon. The ground is trenched typically using a mechanical digging machine;


p.19

the cables shall be laid directly onto the bedding material;

the trench will then be backfilled and compacted with a suitably competent material

up to the required level and finished with a layer of topsoil to aid in the trench

reinstatement.

a suitable marking tape is installed between the cables and the surface; and

the cables are terminated on the switchgear at each turbine and the substation.

5.9 Substation Compound and RES Control Building


MV cables will export power from the wind turbine generators to the RES substation compound

and control building before being transferred to the local distribution network. The location of

the control building is shown on Drawing 02341D1001-06 in Annex 2.

The control building has been designed, sized and positioned to be sympathetic with the

surroundings. To ensure a high level of design will be carried out in the development of the

control building and substation, Mott Macdonald has been commissioned to provide specialist

input to the design process.

The layout shown on Drawing 02341D2222-02 in Annex 2 and elevations shown in Drawing

02341D2223-03 in Annex 2 represent the probable building configurations but are dependent

on a final choice of turbine and detailed electrical design. The control building contains a

control room, RES switch room, utility switch room, SCADA room, storage rooms and welfare

facilities.

The foundations for the building will be designed based on the investigation reports produced

by RSK Environment Ltd. The substructure will likely consist of mass concrete foundations, in

the form of part raft and part strip footing, insulated and tanked in accordance with best

practice and Local Authority Building Control requirements. Trenches or a floor void would be

provided between the foundation and ground floor to accommodate services via a raised floor

system.

The superstructure will likely consist of external and internal walls built off the foundation

and would support the roof. The ground level raised floor system would be supported by either

the walls or directly by the foundations. The walls would be constructed of precast reinforced

concrete, masonry, blockwork or similar.

The control building roof covering will be dark grey tiles or similar, while the external walls

will be finished with a textured grey render. In accordance with Planning Condition 12,

construction of the control building and substation compound will not commence until details

of the exact finishes of the control building have been submitted to and approved by the Local

Planning Authority.

The roof will be a traditional pitch roof construction that complies with relevant design

standards. All doors and window frames will be made of steel or timber, prefabricated to fit

structural openings. All door openings will be sized to comply with the current mechanical and

electrical requirements.

The substation control building will have a domestic electrical system including lights, sockets,

fire alarm and intruder alarm. This will be designed, installed and commissioned by specialist

electrical contractors.

Surface water drainage from the substation and control building will be connected to the wind

farm drainage network, refer Annex 5. Foul water drainage will be provided in the form of a

sealed cess pit at the location as shown in Drawing 02341D2222-02 in Annex 2.


p.20


The control building and substation compound will be constructed generally in accordance

with the following:

the plan area of the control building and substation compound will be set out and the

soil stripped and removed to a temporary stockpile. Storage areas will be stripped of

vegetation prior to stockpiling in line with best working practises;

the dimensions of the control building and substation compound area will be set out to

meet the layout shown on Drawing 02341D2222-02 in Annex 2. Since the overall

footprint cannot be determined until a turbine has been selected, all details present a

worst-case in terms of overall footprint to satisfy the requirements of the Grid

Operator and the necessary equipment and accommodation to safely and efficiently

operate the wind farm;

the building foundations will be excavated down to the level indicated by the

designer. Reinforcement, waterproofing systems and formwork will be installed and

the foundation concrete will be poured;

internal and external walls will be installed/constructed by mobile crane or by hand as

appropriate, services or ducts will be incorporated, and the raised floor system will be

put in place;

the 33kV switchgear is typically installed using a mobile crane or HIAB, the indoor

equipment is then connected, wired, tested and commissioned typically by engineers

supplied by the switchgear manufacturer;

the roof trusses will be lifted into position using an adequately sized mobile crane,

felted, battened, tiled and sealed against the weather;

the doors will be fitted and the external & internal finishing applied including any

fitted furniture. If precast wall are used, doors may be installed prior to erection;

internal and external fittings, finishes and hardware will be installed in the Control

Building. Finishes are to be agreed with the local authority:

o Walls to be finished with render or cladding on all sides.

o Roof tiles to be fibre slating or similar.

o Doors to be made or framed by steel or timber with steel sheeting for

security. The compound area will be re-graded, the electrical equipment

plinths constructed and an over site carpet of single size clean granular

material will be laid.

A palisade fence will be erected around the compound and the area surrounding the

building landscaped as required, returning it as far as practicable to near original

condition;

PIR (Passive Infrared) operated external lighting will be installed on the building and

substation compound to enable safe access and egress during periods of reduced light.

5.10 Grid Connection

Connection to the grid shall be made at Perry Primary Substation. UK Power Networks will

facilitate the connection by installing an underground power line from the onsite substation to

the grid connection point. UK Power Networks will design and construct the connection in

accordance with their recognised standards, planning conditions and any relevant landowner

agreements.


p.21

All necessary consents for the underground power line shall be obtained by UK Power

Networks, and constitute separate consents.

5.11 Anemometry & Communication masts

Two types of mast have permission to be erected at Woolley Hill Wind Farm, permanent

lattice and temporary guyed tubular masts. In total four different masts are required for the

development as follows:

one permanent anemometry mast;

two temporary site calibration and power performance masts; and

one permanent communication mast.

The locations of permanent and temporary masts are identified in Drawing 02341D1001-06 in

Annex 2. Typical details of the masts can be found in Drawing 02341D2224-04 in Annex 2.

5.11.1 Permanent Anemometry Mast

The mast will require its own reinforced concrete foundation and crane pad to allow for

erection, plus associated electrical and communication plant that service the mast. The

foundation construction and mast erection will follow a similar approach to that of the

turbines.

5.11.2 Temporary Site Calibration & Power Performance Masts

Two masts are to be installed within the development boundary.

Temporary site calibration & power performance masts have planning permission to be

erected during construction and will continue to be in place for a period during operation of

the wind farm while accurate wind speed measurements are taken.

5.11.3 Communication Mast

The mast will require its own reinforced concrete foundation and crane pad to allow for

erection, plus associated electrical and communication plant that service the mast. The

foundation construction and mast erection will follow a similar approach to that of the

turbines.


p.22

6.0 DECOMMISSIONING METHOD

In conformance with Planning Condition 4, within 24 months of the end of the 25 year period

pursuant to Planning Condition 3, decommissioning of the wind farm will be carried out in

accordance with Planning Condition 4.

Planning Condition 4 requires that a site restoration scheme will be provided to the Local

Planning Authority no later than 12 months before the expiry of the planning permission for

written approval and will detail measures covering the removal of all ground elements of the

development. The site restoration scheme will include:

the management and timing of works;

the environmental management provisions; and

a traffic management plan.

The works described below are indicative of the decommissioning method which would be

undertaken.

6.1 Site Access Tracks & Temporary Hardstanding Areas

The new site tracks and temporary hardstanding areas would be reinstated to the approximate

pre-wind farm condition, unless otherwise agreed with the Local Planning Authority. Areas to

be reinstated would likely be treated in the following way:

the material used to construct the tracks would be taken up and removed to areas

identified and agreed in the site restoration scheme;

the areas would be backfilled with material generated local to the access tracks and

hardstanding areas, covered with topsoil and reseeded as required;

backfilling of access tracks would be carefully planned in advance to avoid having to

unnecessarily move plant and equipment on freshly reinstated land.

Upgraded tracks would be left unchanged from the conditions used during the operation phase

of the wind farm.

6.2 Wind turbines

The decommissioning of the wind turbines would be the reverse of the erection process

involving similar lifting plant and equipment;

It is anticipated that the turbine nacelle would be taken down and loaded straight

onto the back of transport vehicles and removed from site for reconditioning or scrap;

and

The turbine towers and blades would be broken down into smaller component parts

than during the initial delivery and erection process, into more manageable sections

prior to removal from site.

6.3 Turbine Foundations

Following the removal of the wind turbine the concrete foundation would be removed

to 1.5 m below existing ground level;

The steel foundation insert or bolt ring and any exposed reinforcement would also be

cut back to 1.5 m below existing ground level and treated with a proprietary corrosion

protection system;


p.23

Upon completion of the corrosion protection the foundation would be backfilled with

material generated local to the foundation, covered with topsoil and reseeded as

required; and

It is widely accepted within the construction industry that there is no appreciable

effect on the local environment from buried reinforced concrete structures left in-situ

due to the inert state and classification of concrete.

6.4 Electrical Equipment

The electrical equipment will be decommissioned in the reverse of the installation method

described above to a depth of 1.5m or as agreed with the Local Planning Authority. The

equipment would be dismantled, removed from site and disposed of in an appropriate manner.

Cables may be left in the ground if recovery is not reasonably practicable.

6.4.1 Substation and RES Control Building

The substation and RES control building would be decommissioned by disconnecting and

dismantling all the surface plant. Solid structures such as the building and equipment plinths

will also be dismantled and foundations removed to a depth of 1.5 m. Ducting and cabling that

is practical to remove will be removed to a depth of 1.5 m.

The fence surrounding the compound would be removed and the area landscaped back to its

original state.

6.4.2 Turbine Transformers

The units would be decommissioned in the same manner as they were installed, removed from

site and either disposed of or refurbished by a company certified to handle such materials.

This specialist company will also dispose of any oil or residual waste products in line with

applicable COSHH Regulations.

7.0 RECORDS

Records, as-built drawings, specifications, operational maintenance manuals and residual risks

will be collated and filed in the Project Health & Safety file based upon the requirements of

the Construction (Design & Management) Regulations 2007 or applicable legislation at the time

of decommissioning.
