4.0 WORKING METHODS / SEQUENCE OF WORK
4.1 Permit to Work System
A permit to dig will be requested by Browns and issued by VFL for all earthworks activities, and will be in accordance with the GAL Permit to dig Procedure. The permit will be issued prior to any works being carried out and will include all relevant details and limitations to the works to be undertaken. A sketch or drawing, with all services identified and marked, together with details of protective measures in place, will be attached and issued with the permit to dig.
All existing services, installations, boundaries and known hazards likely to be affected by the works will be located, marked and protected by VFL, who will also liaise with all statutory authorities, Gatwick Airport Ltd - GAL and other service providers as necessary.
The permit to dig will be issued and copied to the Foreman / Supervisor responsible for the works, with additional copies issued to all operatives involved in carrying out the works. The work areas will be walked and the activities covered by the permit will be discussed and explained in order that everyone involved will be aware of the limitations and content of the permit to work. If the works are disrupted or suspended for any significant period of time, then on return the existing permit will be reviewed, and a new permit issued if necessary, to take into account any change in circumstance that may have occurred during any such suspension of the works. The Daily Task Briefing will ensure that all permits to work have been checked and are current. If buried services are encountered during the process all operations will cease and GAL staff will be informed. The services will be recorded and identified if possible. GAL will advise as to the course of action. If the service is damaged then all personnel will retreat to a safe distance and GAL staff will be informed of the occurrence and actions taken as defined in the GAL site procedure.

All services encountered on site are to be considered ‘Live’ until instructed otherwise by the GAL Manager.
4.2 Engineering Control
Engineering control (setting out) will be carried out by VFL Site Surveyors and Site Engineers. The control for the excavations will be provided by the use of batter rails and, profile boards and travellers. Excavations and fill areas will be by way of slope rails set at 20m centres and profiles set at 10m center for formation trimming. In addition, plant may be equipped for use with laser or GPS control for line and level. All relevant information including chainage, offset and details of traveller to be used will be shown on the setting out (written on batter rail/profile board) by the site engineer. Primary and secondary survey control stations will be checked and established by the VFL Senior Land/Engineering Surveyor. Tertiary Control Stations will be established and checked by VFL Surveyors and these stations will be checked by the Senior Land/Engineering Surveyor. Temporary Stations will be established by VFL site engineers but will not be used until the VFL Land/Engineering Surveyor has checked and approved the station for use.
4.3 Location of Services
Existing services, manholes and structures will be located, identified, marked and protected where necessary prior to the commencement of work by VFL. Compliance with any special requirements and documented safety advice from public utility companies, VFL and GAL. Information on retained services must be recorded and the service drawings updated centrally and locally (a copy must be retained on site).
4.4 Earthworks for the Gatwick stream re-alignment and construction of new embankment
The new stream will be excavated in three main phases, with the tie-ins completed last of all, when the existing river is ready to be diverted. Each phase will be as follows, commencing 8 metres away from the existing stream. (See marked – up sketch of excavation / embankment p hases in sections as below – page 7.) The vegetation and topsoil will be stripped from the works area in advance of the main excavation. A permit to dig will be issued by VFL and the area will be set out by the principle contractor as follows – the foul main exclusion zones will be established and marked. The tree protection areas (if any) will also be established and marked. Areas of the existing stream banks that potentially contain Himalayan Balsam seed will be marked on site. The areas of existing Himalayan Balsam seed banks that fall within the new stream embankment will be stripped first, set aside in designated quarantine zones (in areas adjacent to the north of the new stream area), fenced off and clearly marked with signage. Once these areas have been cleared the equipment will be thoroughly cleaned prior to the remainder of the areas being stripped and set aside for re-use. The edge of the excavation will be marked and batter rails provided for excavator and banksman to work to. A laser level will also be set up by the site engineer to enable work to a rough surcharge level. A GPS guided dozer will also be employed where practical to do so. During the topsoil and subsoil strip, areas that require an archaeological watching brief to be in place will be arranged to suit. Where the banks of the channel are required to be raised above existing ground level, suitable site-won material will be spread and compacted in layers in accordance with the engineer’s specification. The area to be raised will be overfilled by at least 1 metre in width, to ensure full compaction to the edges, and it will then be cut back to the required profile as described below. The new embankment is approximately 30 metres wide at the top with profiled stream banks and a meandering stream channel contained within it. A 360 degree excavator will be located in the middle of the new stream embankment, and excavate the clay to the required profile. The new river banks vary in gradient throughout the length of the channel, and so depending on the circumstances, the channel will

either be dug to the required profile using batter rails and a 360 excavator, or where practical (i.e. not too steep) it may be possible to use a GPS guided dozer. Excavated materials to be used as fill in the permanent works will be end tipped (dump truck) or bottom dumped (scraper) onto the fill area. The materials will then be spread and levelled in loose layers, using tracked dozers, to a depth that, after compaction, will not exceed the depth that is specified for the particular item of compaction equipment. Each layer will then be compacted using appropriate self-propelled / towed / smooth drum / tamping (sheep’s foot), deadweight or vibrating rollers or any such combination suitable for the material classification and rate of deposition and in accordance with the contract specification requirements. On completion of each compacted layer, compliance testing will be carried out to confirm that the specified material density has been achieved. Placement and compaction of fill will continue as described above until the line and level of the fill has been achieved. Fill areas will generally be overfilled (300mm summer – 600mm winter) to leave a weather protection layer in place prior to formation preparation.
Whenever fill is to be deposited against the face of a natural slope, or sloping earthworks face, such faces shall be benched immediately before placing the subsequent fill. Excavation within the foul main exclusion zone will, in the most part, be carried out using an excavator working from outside the exclusion corridor. However, it will be necessary to cut the batter using an excavator sitting at right-angles to the stream and therefore the excavator will need to sit above the existing sewer pipes at times in order to do this. It may be considered by the engineer that the large surface area of the tracks, spreads the excavator’s weight sufficiently for no additional measures to be put in place. If not, then protection platforms for the excavator to sit on will be provided (constructed to the same specification as the lorry and plant crossing points – i.e. sleepers). Trial holes to confirm the depth of the foul mains will be carried out in advance. It is assumed that the crown of the foul mains is at least 1m below the new river bed.
4.5 Riparian Planting The new stream banks will be cut into newly compacted and existing clay, the stream channel and stream banks will not receive topsoil. Only the outer banks embankments and slopes will receive topsoil. The planting areas for plant mixes A and B will be demarcated along the newly constructed channel, using wooden stakes. Whilst the planting areas are being demarcated, the average water level along the channel will also be marked out. This will help to aid with the planting of the marginal plug species. The anti-bird fencing will be installed as per the Stream Plug Planting Proposals plan, with intermediate fencing posts installed on opposite banks at appropriate intervals. Blue rope will have flutter tape attached to it before being attached to the intermediate fencing posts with fencing staples. Plants will be put in place as per the Stream Plug Planting Proposals Plan, with individual species planted according to their specific requirements e.g. marginal species will be located adjacent to the water’s edge, with less tolerant species planted higher up the bank. Plants will be planted using a spade or dibber, with a ‘V’ trench created. The plant will be taken out of its container and placed into the sediment, with the soil lightly compacted around it. Once the riparian planting has been completed, the area above the average water level will be hydro-seeded with the riparian meadow mix at a rate of between 5-6 g/m2. Once the hydro-seeding has been undertaken, no machines will be allowed to work within the area, until it has become established. The hydro-seeding will be undertaken after the completion of existing gravel translocation works to ensure the areas are not damaged during these works. Once planting has been undertaken the planted areas will be regularly watered with a fine spray to ensure that the new plugs and plants remain moist and do not dry out or die off prior to the diversion of the existing steam. If necessary the watering of these newly planted areas will continue until the new plants have properly established themselves.

Due to the spawning season for brown trout commencing in late autumn, a walkover survey be conducted prior to electric fishing to ensure minimal impact on fish. Two staff members will follow standard methodology to assess the habitat of the 600m section of the existing Gatwick Stream.
The site will be divided into 300m sections for this survey. Any significant structures or discharges impacting on the site will be recorded. Following this survey and onsite discussions, a stop-net and trash screen will be located upstream from the proposed tie in at section 1 on the attached map below. The trash screen will consist of heavy-duty weld mesh or similar, and will be installed directly upstream (+-5m) of the stop net. The trash screen will be inspected on a daily basis and emptied of any accumulated debris. In addition, a stop net will be located downstream of the works. This will be placed downstream from the proposed flow control structure, but upstream of the sewage outlet. This net will ensure that the area remains inaccessible to the fish. This stop net will consist of fine mesh and will be used to segregate the river system prior to the electrofishing exercise. The stop net will be appropriately secured to prevent fish entry. The net will be inspected on a regular basis. At this point, the necessary EA FR2 Fishery consents will be applied for and will be in place prior to any electrofishing exercise being undertaken.
4.7 Electro-fishing
Electrofishing will only take place in suitable conditions i.e. where the water levels are ~1m-2m in height. We will use standard electro-fishing methodology and use boat mounted pulsed DC electric fishing equipment (3Kw Generator, Electrafish <10amp Pulsed DC Control box, 2 x 400mm anodes, 2 x3m cathode).Water conductivity/Dissolved Oxygen/Conductivity would be tested before selecting appropriate settings on the electric fishing kit. Multiple runs will be carried out throughout the 600m section and remove as many fish as possible into on-board aerated tanks. The fish will then be transferred into tanks mounted on an off-road vehicle and taken downstream or upstream to be released. Suitable areas are to be agreed with the Environment Agency. If there is a possibility of over-stocking the existing habitats (upstream or downstream) the Environment Agency will assist in the relocation of the electro-fished stocks to a suitable and sustainable location identified by the Environment Agency. Following the completion of the tie-ins, the excluded stream areas will be monitored for signs of fish, with additional electrofishing exercises taking place if needed, to relocate any remaining fish up-stream or downstream of the excluded stream channel, to locations previously agreed and assistance provided as necessary by the Environment Agency.
4.8 Translocation of existing Gravels Prior to the silt and gravel excavation and translocation exercise, a detailed tool box talk will be given to the machine operators, outlining the methodology and associated ecological risks. An emphasis will be placed on minimising bank damage and ensuring that appropriate biosecurity methods are in place. A silt curtain will be installed (+10m) from the downstream stop net or as required to prevent any silts from migrating downstream and entering the Gatwick stream during translocation and diversion activities. The excavation of the existing gravels will be under the supervision of an experienced ecological clerk of Works. The existing gravels will be placed at locations as agreed by the Environment Agency, into the newly constructed channel and will be allowed to settle and will remain wetted, prior to the tie-in works being undertaken. Suitable gravels from the existing stream will be excavated using the bucket of a 360 degree excavator, which will sit alongside the stream. The gravel will be loaded into a 6 – 9 tonne dumper and driven to the new stream where it will be deposited at agreed locations i.e. shallow riffle sections. Where the distance between the existing stream and the new stream location within the re-aligned stream is short, the excavator will track between the two locations with the gravel in its bucket and a dumper will not be required. In deeper transition and pool sections within the re-aligned stream, the stream bed will remain as-dug as natural clay and over time, these areas will silt-up naturally. The existing gravels translocated to the shallower riffle sections, will not be placed uniformly in the new stream channel but will be sloped to allow a natural channel to form through the riffle sections during low flow periods. This will also aid in the free passage of fish through these shallow areas during low flow conditions. During the translocation and placement of gravels the Environmental Agency will be in attendance to offer advice on the location and shape of the low flow channels formed through the riffle sequences.

4.9 Stream Diversion The tie-ins will be completed by reducing the “plug” from 8 metres long to 1 metre long, or of sufficient length to ensure bank stability and to safeguard against any seepage into the new channel from the existing stream. These reduced sections will be planted and have existing silt placed in them prior to the final diversions taking place. At the time of the final diversion works, the excavations shall be carried out in such a way as to allow for a controlled, steady flow of water into the re-aligned route. The final 1 metre section will be dug down and shaped to just above the top of the river water level and then the last section below the water level will be dug out using the excavator. The tie-ins will be completed from down-stream to up-stream, so that the water can back up into the new channel and be allowed to settle prior to the excavation of the up-stream ‘plug’ which would then allow the controlled flow of water directly into the new channel. The in-filling of the existing stream will be undertaken from the up-stream end to the downstream end of each section, so that the existing stream can be properly drained down prior to being sealed off at both ends, from the new stream channel.

5.0 ACCESS AND EGRESS ARRANGEMENTS
Site access and egress will be communicated at site induction and on Site Plans which are updated regularly and placed onto site notice boards. The Site Plan will detail the locations of pedestrian routes, vehicle and plant routes, welfare facilities, lighting and emergency equipment. The Thames Water shared access road must be kept clean and clear at all times. There will be no left turns onto Radford Road. Chapter 8 traffic signals and road signage will be in place during the works. Signage will be observed and due regard made to the presence of other road users, particularly at junctions. All haul routes and access ramps must be co-ordinated by PJ Brown and approved by VFL. Haul roads between excavation and deposition areas will be developed taking the shortest direct and even grade route wherever possible. They will be constructed on existing terrain and/or made up using materials arising from the excavations if suitable. Continued trafficking and grading (and wetting) of haul roads will eventually, depending on season and materials used, produce a stable polished surface of low rolling resistance that will, if properly maintained, give good service to dump trucks and other site traffic. Wherever possible haul roads will be for the exclusive use of earthmoving plant, however if other site traffic cannot avoid travelling on such haul roads, priority and right of way must be given to heavy plant. Unauthorised parking of vehicles and storing of materials on haul roads create safety hazards, blind spots and will be rigorously controlled. Where site roads are shared and heavily trafficked by other vehicles including delivery lorries and vans, personnel vehicles, mobile cranes and the like, earthmoving plant will be subject to the same site traffic regulations as the other road users, not least speed limits and priority at junctions.
6.0 TRAFFIC MANAGEMENT Main risks and consideration include the following:
• Segregation of personnel • Pedestrian crossing points • Vehicle crossing points & control. • Impact on the local environment. • Vehicle parking & Maintenance. • Haul route maintenance.
7.0 LIGHTING ARRANGEMENTS
Where permitted, any work activities that continue at dusk, when dark, or in unlit areas, will be illuminated by tower lights installed in fixed positions around the site and all plant and equipment lighting will be operational, clean and maintained. Extra tower lighting will also be installed as required around works areas. See site plans. Working procedures will be modified or adapted to take into account additional hazards created by working under artificial light and at night. Intrinsically safe lighting will be required for any Confined Space access. Emergency lighting will be detailed in the Site Fire Plan for the welfare facilities.
