SITE ADDRESS

North Harrow Community Centre, Station Road, Harrow HA2 6AE

LOCATION OF WORKS

Culvert running to rear of site from north to south west

SCOPE OF WORKS

Replacement of Culvert

Note: This Method Statement has been prepared as a hypothetical worst case method statement based upon the potential requirement to replace, repair or rehabilitate the culvert at

a undefined future date. It provides a detailed system of work based upon information provided.

This method statement includes this document, risk assessments, staged progress plans as well as a programme of works.

A full construction phase health and safety plan would be prepared should any actual work be required. If required, work would be subject to CDM Notification. Environment Agency, Harrow Council Drainage Department and Sewerage Undertaker Drainage Department Environment

Permits will be required.

The existing culvert is understood to be of good structural condition and not likely to be subject to a future daylighting requirement imposed by either the Environment Agency, local

drainage undertaker or North Harrow Community Centre.

The method statement is based upon the worst case requirement to undertake complete replacement works. A No Dig Cured In Place Pipelining (CIPP) technique would be advocated

for any rehabilitation at structural condition grade 4 and in some circumstances grade 5.

A CCTV or man entry inspection would be required to determine the necessary replacement technique in line with the WRC Sewerage Rehabilitation Manual.

PRE-CONSTRUCTION WORKS Stage Description Deliverables

1.

Programme of Works

The Gantt Chart attached is the result of a critical path analysis carried out on logically linked project activities contained within Primavera P6 Project Management database.

The programme has been developed with the aim to schedule all major activities required to take the project from award to a successful handback. This has necessitated the need to review each element of work with respect to interfaces, availability of resources, buildability, as well as documentation requirements.

As such, any deviations from the construction strategy will need to be considered separately to mitigate any adverse impact on the programme. During the development of the programme a number of key items were considered

Access requirements and impact on programme Weather conditions these works have been planned for

winter months with peak flows in Yeading Brook Landtake and existing topography Road infrastructure and neighbouring properties The need to install sheet piles adjacent to the culvert along

the boundary line with the existing neighbouring property Interface Requirements between the various subcontractors Interface requirements between Harrow Council, EA and the

statutory authorities Sequencing / Availability of the services The need for programme certainty in order to achieve

realistic milestones for works carried out in a safe manner

We have concentrated on the critical requirements rather than the details within each work element but have made an assessment of the possible construction issues and the complexities involved.

This sequence will be refined at the time of construction works and site surveys prior to the final submissions to Harrow Council and the EA

Programme of Works.

6.

Procurement

The first action by the PM will be to notify the Statutory Authorities, giving a period of 10 week notification lead-in time.

The Culvert Replacement Contractor will be appointed based on preliminary drawings and a negotiated tender process.

The M&E Contractor will also be appointed based on a brief and negotiated tender process. M&E service drawings will be produced by the contractor for any diversions and for the removal and replacement of the storm and foul water drainage that are present in the 3m culvert exclusion zone.

The Sheet Piling Contractor will be appointed based on Schedule of Rates and a performance specification. This will be done in conjunction with the neighbouring property owner and with the permission of Harrow Council.

Once the design and permits have been received by all third parties, the orders will be placed for the precast concrete culverts, the M&E supplies and consumables as well as the sheet piles. All these items will be in ready availability and off the shelf items, and will not have long lead-in periods.

5.

Preparation for Permanent Works

Check all relevant site / apparatus drawings and use CAT & Jenny locator. Mark location of apparatus.

Check all plant and equipment prior to use ensuring that it is in good condition and within its service, test and / or calibration date.

The site will be prepared and all top soil will be stored along the south east side of the site. The top soil will be restored after the permanent works and replaced to its original condition.

The balance of the excavation (about 200mm deep) will be removed and carted away from site. It will be examined for contam and the disposal done appropriately.

The removal of this soil will be done through the South Exit into Station Road.

Excavation: Underground Services

Hand Tools

6.

Access to Works

Establish access road (crash decks) to excavation point with the use of Timber Crane Mats (3m x 1m x 140mm thick), with granular aggregate and fine sand blinding. The mats will be 140mm thick in order to cater for crane and piling rig loading.

Pre-commencement photographs to be taken to establish existing condition of site to provide future reference for reinstatement.

Crash Decks / Trackway

Dilapidation Survey

7.

Sheet Piling Works

The piling rig will be placed on the crane mats as shown on the drawing. The reach of the piling rig will go over the fence line and on the other side of the boundary line

The sheet piles will be installed using a telescopic leader rig, which will pitch and drive the sheet piles. Once the piles are pitched they will initially be driven using vibro hammer techniques on the leader rig.

The piles will be driven with the vibro hammer until they reach refusal or design toe level (10m estimated subjected to sheet piling design).

Method Statement


SITE METHODOLOGY


Where piles reach refusal they will be driven using an impact hammer to design toe levels. Where any piles achieves refusal prior to reaching the design toe level, after use of the impact hammer, the level and location will be recorded and a temporary works check carried out to ensure suitability.

The sheets will be fully clutched to provide a tight seal between them. The sheets will be propped within the safety zone in the neighbouring backyard in case additional stability will be required.

8.

Excavation and Demolition Works

Begin excavation with machine excavation.

Where using hand-held pneumatic breakers then work rotated in team to ensure that no one person uses vibrating equipment for more than 2 hours per day.

Undertake excavation carefully using a banksman to look watch out for signs of services (tapes, tiles etc), using blunt hand tools to excavate near suspected buried services. Look for signs of oil or chemical contamination.

Build temporary ramp with suitable fill to enable CAT 331 wheeled excavator access into trench. Note: There are basement and water storage tanks underground which form part of the building footprint.

The excavator will be fitted with a breaker in order to break up the sides and base of the concrete culvert, and deposited onto the crane mat surface.

Install stop logs to prevent vehicles falling into excavation.

Store spoil away from edge of excavation and away from drains. Consider installing guttering and sandbag pile to prevent silt loss. Cart away using 12 Ton tippers at both ends of the site.

Any excavations greater than 2 meters deep must have barriers that can physically prevent a person falling.

Access into culvert must be via ladder, with two points of access provided if necessary.

Disposal of water from excavations

Prior to dewatering or storage of excavated material, identify local drainage systems and implement controls against loss of silt

Problems with water disposal will be avoided by: preventing water entering excavations using cut off ditches using pump sumps in excavations discharging on to hard surfaces into surface waters protection of the pump inlet to avoid drawing in debris minimising disturbance of standing water

12.

Delivery of culvert sections (6.3 tons each)

Contractor will agree with the culvert supplier well in advance the place and approximate time of delivery.

Provide a hard access for standard delivery vehicles. Provide a Demag AC40 City Crane or equivalent capacity. Ascertain details of the lifting method used by the supplier. Provide all handling equipment necessary to operate the

lifting method on site. Consult the box culvert supplier to ensure that the proposed

method is acceptable. Protect the box culvert and particularly the joining surfaces

from damage while lifting. Ensure complete safety of operatives.

13.

Preparation of Culvert Bed Base

Keeping to the specified line and gradient, the trench should be excavated to a width equal to the box culvert width plus 300 mm at top of excavation / top of embankment.

Follow the normal requirements for safety when working in trenches.

Full load bearing capacity of an installed box culvert line is achieved with uniform support at the base.

Carefully trim the formation to the required depth and gradient making allowance for the thickness of the bedding.

Excavate local hard or soft areas of the trench bottom which may cause uneven settlement and replace with well compacted backfill selected to give uniform support.

Maintain a dry formation so far as possible by diverting water courses, pumping water from the trench or other means.

Lay well compacted selected granular material over the full width of the trench to a minimum depth of 200mm having first removed any protective layer.

Blind the surface with fine material to assist levelling. Having achieved a flat, well prepared base, it should not be allowed to deteriorate.

Lay the bedding only a minimum distance ahead of the laying of box culverts. Keep off the prepared base so far as practicable.

Excavation: Persons and equipment falling into excavation

14.

Laying the Culvert

All culverts will be off-loaded from the tipper directly into the trench base, with the use of the Demag AC40 City Crane.

The box culvert line will be laid from the downstream end with sockets facing upstream to receive the next box culvert.

Inspect the box culvert before laying to ensure that the jointing surfaces are clean and that no damage has occurred in handling and transport to the site.

Lower the box culvert carefully on to the prepared base aligning the spigot with the socket of the unit already laid.

Prevent loose surface bedding material from entering the joint space during positioning of the unit by placing a hardboard strip beneath the base joint.

If any adjustment to level is necessary, remove the box culvert and adjust the surface level of the bedding. Local packing will not be used to adjust the levels

Applying the Jointing Material

The strip should be applied to the box culvert just before it is laid in the trench. The inner and loping faces of both the spigot and the socket will be cleaned and primed

Place the strip in the internal corner of the socket Cut mitred ends and join the strip at corners All joints will be checked to ensure that the strip is

continuous. Joints will be closed by pulling against the box culverts

previously laid. Anchoring the cables firmly at each end, take on the crane the weight of the box culvert being jointed to reduce frictional resistance at the base of the box culverts.

Allow for a load of approximately one tonnes per metre of strip to compress the strip.

Apply heat, as recommended, to soften bitumen based strip when the weather is very cold.

Close the joint with cable pullers to the specified nominal gap.

On completion, make good any holes used for lifting and laying.

Joints in box culverts of will be pointed internally to increase hydraulic flows in the culvert. This can take the form of an elastometric or bitumen based sealant

Backfilling over the Culvert

Backfilling should commence as soon as possible after the box culverts have been laid.

Fill the trench to the level of the top of the box culvert working evenly on each side.

Use selected backfill or imported Type 1 material well compacted in layers not exceeding 200mm

Heavy vibratory equipment will not be used for these works. Continued filling over the box culvert and compacted in

1. Not applicable.


1. For planned works prior consent shall always be sought: - Where discharging directly to a watercourse prior application shall be made to the Environment Agency (or other

relevant Land Drainage Authority) for Discharge Consent. - Any work within 8 metres of a watercourses then prior Consent for Works Affecting Watercourses (Land Drainage

Consent) shall be applied for from the Environment Agency. - For dredging involving the proposed disposal. A Exemption to Environment Permits to spread waste dredgings to

riverbank or agricultural land may be applied for. This will consider contamination and flood risk. Allow 20 days for application.

- Where Over / Cross pumping or for any discharge to a foul / combined sewer then a Discharge to Foul Sewer Consent may be required from the local sewerage undertaker.

- For discharge of potable water from mains or other water facility including service reservoirs, borehole testing etc consent is required if the discharge is via a pipe greater than 229mm in diameter. If it is less than 229mm diameter consent is not needed but significant discharges will be issued with a duty of care letter.

2. For emergency response work then the Relevant Statutory Body (Environment Agency or Sewerage Undertaker) shall be notified as soon as practicably possible.

Operational Control

1. Water should preferably be retained in the same drainage system. 2. Abstracted waters must be free of silt, visible oil and unnatural colour or odour. The clarity of the water must first be checked

by carefully taking a surface sample in a transparent container. The operator should minimise the disturbance of the water in the duty or chamber as this may stir up any settled silt. See RAG.018.4 Excavation Dewatering. If oil, odour, colour or silt is present and cannot practicably be removed then it shall be transferred to a licensed waste disposal site or treatment facility [RAG.049].

3. Care will be taken with the discharge of any pumped water to the watercourse. Pumped discharges will be made using a pump of suitable size for the situation and at a rate which will not cause riverbed disturbance. The discharge pipe to be frequently moved to prevent erosion of bank or bed, or settlement of solids.

4. Where operating in a combined system near to a sewer overflow, prior consideration should be taken of the volume of water required to cause operation of the overflow, and restrictions implemented to prevent a discharge to surface waters.

5. Consideration should be given to if the stretch is being used for stormwater retention, where overpumping may bypass this. 6. If dredging / clearing watercourses care must be taken. Incorrectly disposed silt can lead to contamination of water or land.

Disturbance of the silt can mobilise oil and diesel contamination. Dredging activities can also uncover bulky wastes such as bicycles, shopping trolleys, beds, fencing etc. See RAG.049 Waste.

7. Sewage Contamination Issues - Wash back to sewer any waters around manhole head. - Where airborne transfer is an issue, for instance, near a school, hospital, public park or other sensitive areas dampen

area above manhole. Do not use disinfectants unless authorised to do so. - If any wastes are to be removed, see RAG.015 Drainage Cleaning and Tankering.


1. Do not pump foul into surface water or surface water into foul. 2. Use of vactor recycling units must be monitored to ensure they do not use sewage-contaminated water in surface water

drains. Type Standard Personal /

2. Where the hooking device is not part of the bucket, the bucket should be removed in order to improve visibility and reduce the weight being lifted. If the bucket is retained, then the weight of both the bucket and quick-hitch has to be added to the load when determining whether the load is within the rated capacity.

3. Exclusion zone established around excavator and route. 4. Effective communications must always be maintained between slinger and operator. 5. The excavator operator should always make use of the safety lever (safety armrest)

whenever the slinger is in the danger area, and ensure cuffs of coat are secured. 6. Ensure that the acoustic/visual warning device indicating the load moment, is switched on

prior to any lifting operation. Prohibitions / Restrictions 1. No person to enter exclusion zone during lifting operation or movement of load.
