3.0 Pre-commencement Requirements

3.1. Geology The Piling Director will have satisfied himself prior to the commencement of the contract with regards to the geology of the site and any effects it may have on the Works. The Principal Contractor has provided a Soil Investigation Report, carried out by Southern Testing Limited.

3.2. Network Rail The site is adjacent to a Network Rail Running Track so the Precaution given in Network Rail Standard: NR/L3/INI/CP0063 apply, specifically:

• A Temporary Works Design submission of Forms F002 & F003 for the working platform will be made to Network Rail.

• No section of the site will be within a Restricted Zone, i.e. a zone in which the collapse of the rig would impact on the Network Rail Assets.

• A Temporary Works Design submissions Forms F002 & F003 will be submitted to and accepted by Network Rail.

• The piling platform is to be inspected weekly and a record made on the WPC. • The orientation of the rig can be either perpendicular or parallel. • Piling rigs should operate in their normal mode. • The piling platform must extend 2.0m beyond any pile position or to a boundary. • Spoil spin-off to be close to ground and below hoarding height.



• A network rail representative will be in attendance at their discretion during piling works

3.3. Existing Services The Principal Contractor will carry out any inspections for existing services and probe for existing sub-structures. These areas are to be removed or clearly marked prior to any Piling Works. A 5m exclusion zone will be maintained around the Piling Rig in operation, and piles recently cast will be covered with a metal grate.

3.4. Working Platform 3.4.1. The Principal Contractor will provide the Piling Crew with a firm and level hard

standing Working Platform as specified, based upon the BRE load cases provided by JMP for the Rig to be used.

3.4.2. Attention needs to be given to the edges of Working Platforms: determine how near the edge of the platform plant can be permitted while avoiding instability. A minimum distance of half the machine width is usually required. Clear marking of the working area is essential.

3.4.3. Sites where there have been cut and fill operations, or where plant is required to operate near slopes or batters, will need to be checked for slope stability with the additional loading of the plant in place. Sloping sites present particular problems for stability, which should be addressed in the design – some plant may not be stable at 1 in 10.

3.4.4. This Working Platform will be maintained throughout the duration of the Piling Works. If obstructions are removed the mat must be properly reinstated in accordance with the original Piling Mat Design.

3.4.5. The Working Platform, including ramps and accesses, is to be used only by plant for which it has been designed.

3.4.6. Any areas that do not form part of the Working Platform must be clearly indicated to the Piling Supervisor.

3.4.7. The working platform certificate must be signed before the commencement of any works on site.

3.4.8. Any parts of the Piling Mat deemed unacceptable by the Piling Foreman or Site Manager must be rectified straight away.

3.4.9. The Working Platform level must be provided before any Piling commences.

3.5. Access Access routes onto and off site will be as agreed with the Principal Contractor. The Rotary Bored Piling Rig will be transported to site on a low loader capable of carrying the Rig. The Rig will track itself off the low loader and will not be lifted off by means of a crane. If necessary, a wide enough ramp will be constructed to provide a safe access onto site for the Rig and timber boards/spreader plates placed to protect any existing surfaced areas and kerbs, c/o the Principal Contractor.



3.6. Setting-Out of Piles

5.0 Methodology

This method statement explains in depth the rotary bored piling technique. 5.1. Description of the Works

The main risks associated with the Piling operations are:

i. Failure of Piling Rig

ii. Failure of Piling Platform

iii. Spoil removal during Piling operations

iv. Open Bores

v. Personnel falling into freshly concreted bores

vi. Collision and crushing by Piling Equipment

vii. Lifting and placing reinforcement

viii. Working near railway viaduct applicable to this project To overcome these potential risks, the following safety features will be implemented to ensure a safe method of working: - GENERAL Piles will be constructed with a diesel powered track mounted Rotary

Piling Rig. WORKING Working hours will be as follows: Monday to Friday 08.00 – 18.00 hrs

- Workmanship will be consistent throughout the duration of the Piling works. - All JMP crew and subcontractors will be focused on their work throughout the

working day - It is important that all JMP staff take the breaks that they are entitled to

throughout the day. - The quality of Piles, including steel cages and test cubes, will be to a

consistent high standard and this standard will not drop at any time i.e. end of shift / week / last day before holiday period etc.

- All staff will be deemed competent to carry out the task in hand.

ACCESS Access to the Piling area will be as provided by Mc Aleer & Rushe. Access ramps between working areas to be no greater than 1:10 gradient.



LIGHTING Task lighting as fitted to plant will be provided and maintained by JMP. General/safety lighting for the access and working area will be provided by Mc Aleer & Rushe if necessary.

RIG

Mobilisation - The Rig will be mobilised on the signed off Pile mat area. The Pile equipment will be a diesel powered track mounted Rotary Piling Rig. Before erecting the mast, the tracks of the machine will be extended to full width to provide full stability. The hydraulic Piling Rig is self-erecting and the mast, during mobilisation, is lifted from the travelling horizontal position to the vertical working through a series of rams positioned on the mast and Rig body. Protective mats (ply sheets) necessary to minimise the risk of damage to existing surfaces or third party property will be provided by Mc Aleer & Rushe. All hoardings, fences, noise and splash barriers, statutory warnings, flagmen etc as necessary to protect the works, plant, materials, personnel, third party property and the general public will be provided by Mc Aleer & Rushe. This shall include protection from exhaust, oil, grease etc. Equipment and Material Delivery - All construction traffic including the Piling Rig, delivery vehicles and concrete wagons will access the site works using the designated Works Access’s only. On arrival to site all equipment and material deliveries will report to the person in charge prior to off loading. All deliveries will transit through the site with a Banksman present at all times. No keys are to be left in unmanned machines. Equipment and Material Storage - Equipment and materials will be stored adjacent to the Piling area. At the end of each shift the Rig shall be left in a safe and secure manner.



WORKING PLATFORM Piling Platforms: The piling platform designed by Consulting Engineers is based on the BRE Load cases for the Soilmec piling rig. The platform will be installed by Telford Homes as per the specification designed. The working platform certificate (WPC) will be signed off by the relevant parties – designer and McAleer & Rushe. The working platform certificate shall be issued in conjunction with a Form C. A copy of the completed ‘working platform certificate’ shall be kept on site. The piling platform shall extend 2m beyond the working area. Testing of the working platform will include plate bearing tests on each piling platform. Inspection of the piling matt will be carried out regularly by McAleer & Rushe any anomalies in the piling matt will be addressed immediately by McAleer & Rushe. There will be no excavation of the piling platform where the piling rig is working until the piling rig is finished piling on that platform. Any unsupported pile shafts – where the pile cut off levels are low – will be correctly backfilled following the completion of pile construction so there is no hole left open at the end of each day.

Orientation of the Piling Rig: The piling rig will track straight onto the piling matt facing directly onto the tracks (See below). This will be implemented at all times, the banksman will be in full attendance whilst the piling rig is tracking on site. This will be carried out where the tracks are within the falling radius of the piling rig. The Soilmec Piling rig will track from pile to pile as below.

Platforms for tracked plant: good practice guide to the design, installation, maintenance and repair of ground-supported working platforms – BRE 2004). The working platform will be REGULARLY INSPECTED, MAINTAINED, MODIFIED, REPAIRED, and REINSTATED to the as-designed condition after any excavation or damage, throughout the period when the Piling Rig and equipment is on the site by Mc Aleer & Rushe A completed copy of the FPS Working Platform Certificate (FPS/WPC/4) Appendix F signed by an authorised person from the Principal Contractor shall be given to each user of the working platform prior to commencement of



any works on site and the Working Platform Regular Inspection Log is to be maintained by the Principal Contractor in accordance FPS/WPC/4 Guidance on Working Platforms for Tracked Plant 3.1-3.3. This is the responsibility of Mc Aleer & Rushe. Temporary Works Design for the working platform should in accordance with the approved Forms of F002 & F003 submitted to Network Rail.

PILING SEQUENCE

The Piling sequence will be generally as per agreed with Mc Aleer & Rushe. The piles will be constructed in such a manner that no damage will be caused to piles previously constructed i.e. cracking, clashing or disturbing.

PARTY WALL

Mc Aleer & Rushe to have in place a procedure for Piling works adjacent to Party Walls.

PILE BORING

The position of each Pile will be set out by Mc Aleer & Rushe and referenced with the Pile number prior to drilling. Whilst the mast of the Rig is in a vertical position the tip of the boring tool will be lowered and manoeuvred to be directly into the centre of the relevant Pile location pin. Prior to the commencement of drilling, the mast will be checked for verticality in both orientations by reference to a spirit level.

Based on the Soil Investigation Report, casing may be used. If used, the boring tool will pre-drill to permit the temporary casing to be placed as necessary. The casing will be lifted by the Piling Rig and inserted into the bore to achieve a seal by the operation of the Rig. The bore will be extended by the Piling Rigs auger down to the required depth in accordance with the relevant drawing and Pile schedule.

During boring, the boring tool is extracted and spoil deposited adjacent to the bore. At regular intervals during boring, spoil arisings built up adjacent to the bore will be cleared by the attendance excavator. This will be removed at a later date by Mc Aleer & Rushe to a designated stockpile.

Mc Aleer & Rushe to appoint a 360° excavator for handling waste materials and Pile arisings.

Once the correct depth has been reached this will be checked by tape and recorded on the Pile record sheet.

CONCRETING



Concrete of specified mix 35N DC-4 S3 shall be used to construct the Piles. The concrete will be delivered in ready mix trucks using the designated access routes and will be routed through the site to the Pile head position with a Banksman in attendance at all times. Prior to concreting, a JMP employee will inspect the concrete ticket, ensuring the concrete is of the correct specification. The concrete will then be visually inspected to confirm its satisfactory condition prior to each discharge into the bore. This stage of the operation will be directly controlled by the JMP Banksman using signals to the concrete wagon driver. Concrete will be placed by direct discharge into the Pile.

REINFORCEMENT The reinforcement will be delivered in straight lengths of reinforcement bar and helical links and placed in a designated area as agreed with Mc Aleer & Rushe site management team. All reinforcement will be kept off the ground. This steel fixing station will have ‘tressels’ where the reinforcement will be placed as the cages are fixed by the competent steel fixers. The steel fixers will be working under the supervision of JMP and will have the relevant training cards, and will be briefed on this JMP document with sign-off of same. The Banksman will ensure that the reinforcement is placed on the ‘stands’ or ‘tressels’ in a safe manner so the steel fixer can commence cage fabrication. The steel fixer will fix the cages as per the design schedule. The Piling foreman will inspect the cages after fabrication. If cages are larger than usual a pre-fabricated option may be preferred. In which case the attendant excavator will be required to remove the pre fab cages from the delivery lorry and place in a designated lay down area. The cages will be lifted via the attendant excavator and lifting apparatus to a storage area agreed with Mc Aleer & Rushe with a slinger / banksman present. All lifting equipment including chains, slings etc will be fully certified. The lifting procedure will be in accordance with the Lifting Plan. Piles with tension reinforcement will be placed using the main winch of the Piling Rig. The Pile cages will be placed on the Piling mat (laid out). The ‘hanging wire’ will be fixed to the cage and the shackle attached to the safety bar. The cage will be lifted into the cased Pile. The safety bar will sit or rest on the casing, ensuring there is no personnel coming into contact with the placement of the cage. Should the bar require repositioning there are two



safety handles on either end of the safety bar away from the hanging wire and cage. The safety cage will be fully certified and tested. The Piling Rig or attendant excavator will lift the cage from the horizontal to the vertical, slew around and lower the cage into the Pile bore (refer to image below)

Debonding foam will be placed on the reinforcement cage projection bars if requested and allowed for. JMP cannot be held responsible for debonding foam that slides off the projection bars during the concreting operation. Debonding foam is placed to ease the breaking down of concrete; concrete will still need to be broken down by hand for at least the final 300mm above cut off level without debonding foam (The use of mechanical crunchers may snap off reinforcement projection bars and fracture the Pile shaft). Mushroom caps will be provided and fitted to the top of all reinforcement projection bars. When Piling operations have been completed the process shall be repeated at the next Pile position. No Piles will be left open hole, and an exclusion zone must be maintained around recently cast Piles for safety reasons.

Once the Piles have been trimmed to cut-off level, integrity testing may be undertaken.

Throughout the Pile construction process, the appropriate construction and inspection records and activities will be maintained in accordance with the Safety Management System, Works Procedures and the Specification

5.5. Testing Regime

One set of 4no. Concrete cubes will be made per day for each Piling Rig by JMP. The Principal Contractor will supply an 110V outlet for the concrete curing tank; failure to do so may result in low cube strength results.

Holliday Concrete Testing Ltd will perform the testing of concrete cubes and hold UKAS testing accreditation.

Pile Integrity Testing - All Piles will be integrity tested after completion. No Pile integrity testing shall take place under 5 days from the time of cast, and may only be performed after the Pile has been satisfactorily trimmed for testing purposes. The trimming is required to remove surface latency from the Pile and should result in minimum damage to the piles. Mc Aleer & Rushe is to arrange the integrity testing through JM Piling (Geraldine Coleman 02076929565), giving at least 48 hours notice.

Programme

The work will proceed generally in accordance with Mc Aleer & Rushe Programme.

Guidance on working platforms for tracked plant

1. Design

1.1. The HSWA 1974 and CDM Regulations 2007 require the Principal Contractor to appoint competent Designers in respect of Working Platform design. This legislation explains how competence can be assessed by reference to professional qualifications or professional memberships and by reference to practical experience of the design of working platforms. Principal Contractors must be satisfied that a competent Designer has been appointed by them in accordance with the relevant legislation before they complete and sign the WPC.

1.2. The stability of tracked plant is fundamentally dependent upon the provision of a suitable and sufficient working platform. It must be properly designed and installed to a recognised standard. Whilst the same type of rig may be operated by different companies, the design bearing pressures may differ due to the specific operating configuration of the rig and/or any modifications. Details of the plant to be used and bearing pressures will be provided by the specialist contractor in advance of work commencing.

1.3. Working platform design is extremely sensitive to the bearing pressure and type of fill used in the platform. (For example, changing the angle of friction of the fill from 35 degrees to 45 degrees can halve the platform thickness.) It is therefore advised that the Designer may have to adopt conservative/cautious estimates of platform shear strength unless higher values can be demonstrated by testing or with reference to appropriate published data.

1.4. The working platform must be free draining to prevent the build up of water and slurry. In the case of fine-grained sub-grades, a separation/filter membrane should be installed beneath the platform material to inhibit ‘pumping’ and infiltration of the fine-grained soils up into the platform material during wet weather (which can impair platform performance and increase maintenance costs).

1.5. Proof testing of the platform can be carried out with a suitably sized circular plate subjected to the maximum design loading. Such testing, as part of an appropriately designed testing regime, should highlight any gross inconsistencies in platform performance. Potentially, significant savings in platform thickness and cost may be realised by adopting a more detailed testing strategy.

1.6. The working platform must have a specified design life which starts before delivery of the piling equipment and ends on completion of all piling works. This includes load testing, integrity testing, investigation of non conformances and any remedial works.

1.7. The specialist contractor is to advise the Principal Contractor at the earliest practicable opportunity should the specialist contractor become aware of any circumstances relating to the working platform that renders it unsafe.

2. Installation

2.1. The FPS Working Platform Certificate is mandatory for all sites where a rig or attendant plant operates. It must be signed by an authorised representative of the Principal Contractor. This signature confirms that the legal duties required under CDM have been carried out.

2.2. If the working platform is to be constructed or removed in phases while piling works are ongoing, then the extent of the platform must be clearly defined on the certificate and, in accordance with good practice, physically on site. This is particularly important where the platform material is removed from an area previously made available to the specialist contractor.

2.3. The working platform provides access for all plant deliveries, sub-contractors and personnel associated with the specialist operations. Properly designed and installed the working platform could also provide suitable and safe access for following trades for the whole project.

2.4. Poor definition of the edge of the working platform is a major cause of tracked plant instability. It is good practice that the working platform should extend at least 2m beyond the pile position/edge of the building to ensure sufficient safe working area for the specialists personnel and attendant plant. Where having to work within this 2m zone is unavoidable the Designer is to be informed of the requirement to design the platform for working up to its edge.

2.5. Where access ramps are used to move between working levels these must be of sufficient gradient and width to allow the plant to move safely with the stability constraints of the machine. Ramps must be in a straight line between working areas.Rigs and cranes cannot change direction on ramps. Where a change in direction is required, this must be on a flat level platform.

3. Maintenance, modification, repair and reinstatement

3.1. The working platform must be kept free draining. Water and slurry which is allowed to build up on the working platform can hide such hazards as recently constructed piles, trip hazards, uneven or unstable ground, services and excavations. Slurry can be transferred to work equipment which increases the risk of slips on steps as well as difficult handling of work tools.

3.2. Obstructions encountered during installation of the piling works will generally require excavation to remove them. This can create a ‘soft spot’ which can result in the rig overturning. It is essential, therefore, that any excavations made in the working platform are reinstated to the designed standard, including any reinforcement and separation filter/membrane.

3.3. The working platform shall be subject to regular inspection by a competent individual appointed by the Principal Contractor (e.g. the Temporary Works Co-ordinator) throughout its design life and after any reinstatement or any works which might have modified it. Any damaged or inadequate areas identified must be reinstated to the designed standard. Following the regular inspection, the Working Platform Regular Inspection Log shall be signed by an authorised representative of the Principal Contractor and issued to the specialist contractor with a layout drawing of the working platform amended as appropriate.

4. Working Platform Layout

4.1 Items that must be included and properly located on the working platform layout drawing and be notified by the Principal Contractor to the specialist contractor would include: detail of platform edges and 2m delineation, trial pits, services or voids, areas of backfilling, known underground basements; areas that are covered by the certificate or permit, test locations (if specified by the Designer of the platform) and any other feature that may affect the safety of operations.
