METHODOLOGY
Before any works commence, the following points must be fulfilled……………

All Collins employees are to receive a site induction by the main contractor, Winvic.
All Collins employees must understand the contents of this Method Statement and associated Risk Assessments with a signed briefing register to confirm this.
All Collins employees must provide a current CPCS/CSCS card for photocopying.
Winvic must provide a ‘Permit to Dig/Work’ detailing any services traversing the site. It is Winvic’sresponsibility to investigate and protect all services within the site.
The holes and trenches will be dug with a tracked 22 tonne excavator which will be delivered to site on a HGV Low-loader.
The trial holes and trenches will be dug in a careful and safe manner to record and preserve any findings.
Once the archaeological study is complete the holes and trenches will be backfilled and made safe once all the information is recorded and any potential findings carefully removed.

SITE CLEARANCE
Any topsoil, unsuitable or deleterious material will be extricated and relocated in landscaping areas.
MANAGEMENT OF ACMs
There are ACMs present within the areas of made ground on site. During the excavating and processing of the different materials on site, trained personnel will supervise the works to identify, remove and dispose of any ACMs found. They must have completed a none-licenced Asbestos removal course and wear the correct PPE/RPE. If any broken pieces of ACMs are discovered they will be sprayed with a water/PVA solution to prevent particles becoming airborne. Any ACMs collected must be double bagged and placed in a lockable container. All ACMs collected from the site will be disposed of at a certified Asbestos disposal company with a copy of the hazardous waste consignment note being sent to Winvic Construction management to be kept on record.
Hazards
Breathing in Asbestos dust is dangerous, it can lead to a number of diseases, these include;

Asbestosis or Fibrosis - scarring of the lungs.
Lung Cancer.
Laryngeal cancer- cancer of the larynx.
Mesothelioma a cancer of the inner lining of the chest wall or abdominal cavity.

There are no known cures for asbestos related diseases
Precautions:
1For all work with Non – Licensed Asbestos, disposable overalls, gloves must be worn.
2Suitable respirators (P3 with face fit) must be worn where the control limits are likely to be exceeded.
3Work areas must be cordoned off and cleared of all non-essential personnel.
4Overalls must be removed with the member of staff entering a personal decontamination unit prior to entering and using any welfare facilities; canteen, toilets, drying rooms etc.
5Overalls must be discarded on completion of the operation and disposed of as Asbestos waste. (double bagged and sealed). This also includes the disposable respirator, gloves, overalls and any wrags/sponges used for decontamination.
6After handling materials containing Asbestos; hands and boots must be thoroughly washed and decontaminated before eating, drinking, smoking or carrying out any further work.
Additional PPE – Asbestos Removal
All operatives involved in the picking of asbestos or in the immediate vicinity of the works will wear disposable hooded overalls of type 5 standard, P3 half mask respirator to EN140:1996, EN141 & EN143 and latex coated gloves to EN388.
Training
Under the ‘Control of Asbestos Regulations 2012’, all operatives involved in the picking of unlicensed asbestos must have undergone suitable training and hold a valid certificate issued by a competent training provider. Collins Earthworks will ensure that all operatives are suitably trained with non-licenced asbestos removal/asbestos awareness with annual refreshers prior to commencement.
TRIAL HOLES AND TRENCHES
Before any excavation is begun, any known underground and overhead services onsite are to be clearly identified by a member of the Winvic site management team to ensure the dig is nowhere near any known live services. A permit to dig will be signed off by Winvic before any digging commences.
Prior to any excavations a photograph will be taken of the area to be excavated. Each trench will then be mechanically excavated using the 22 tonne Volvo excavator with a smooth/toothless ditching bucket with caution. The machine will be constantly monitored by an archaeologist and under instruction of the archaeologist the machine operator will stop work immediately. Before any hand digging takes place by the archaeologist another photograph of the excavated area will be taken to show depth that has been mechanically dug. Should it be necessary to leave a trench open overnight, it will be fenced on all sides with netlon fencing and iron road pins which will be provided by Winvic. Once the archaeological evaluation in each trench is complete, the trench will be backfilled, replacing the strata in the reverse order to which it was excavated, returning the site to the state in which it was found.
BACKFILLING
Once the archaeological evaluation in each trench is complete, the trench will be backfilled and compacted, replacing the strata in the reverse order to which it was excavated, returning the site to the state in which it was found. All the material will go back in the excavation and it will be levelled and left in a clean flat state not leaving any trip hazards.
BULK EARTHWORKS
Collins Earthworks will commence this operation on 07/09/2015. The cut and fill operation will then commence. The areas of cut will be trimmed with a D6 dozer and excess material loaded on dump trucks by 360 excavators. This material will then be transported to the fill areas where it will be tipped and levelled under the instruction of a D6 who will then level the material ready for compaction by a ride on roller. No areas of formation are to be cut and left open to the weather. All materials are to be placed and compacted in accordance withclause 612 of the Specification for Highways Works/Trenter & Charles Specification.
BULK FILL MODIFICATION
As the earthworks progress, material that is not suitably competent as fill in its current form will be modified with lime. This material will be pushed out into the areas of fill on top of good material. This none suitable material will be pushed out in a layer approx. 300mm thick, this will be done with the use of the D6 dozer. Quicklime will be applied to the surface in an accurate and uniform dosage using a spreader/ mixer. Wind speed and direction will be monitored using a windsock. Operations will be suspended in high winds. Mixing of the quicklime with the unacceptable material shall be carried out using a Gutzwiller mixing drum to produce a homogenous mixture throughout the full depth of treatment. The treated material will be compacted to ensure that reaction occurs about each particle of soil. Buxton lime has a very quick reaction time but it may be necessary to let it slake a while longer and even rotovate the material again to achieve the correct pulverisation. The material will then be compacted in accordance withclause 612 of the Specification for Highway Works in external areas or Trenter and Charles under the building footprint. After allsampling has been taken and the layer has passed all post checks, we will proceed to place another 300mm layer of excavated material on top for testing and possibly treatment in the same format as previously described.
SUB BASE REPLACEMENT
Quicklime will be applied and mixed to ameliorate the soil prior to the addition of the cement binder. It will be added and mixed to the soil not less than 24 hours or more than 72 hours before the subsequent addition. During this period it will be ensured that any quicklime added to the soil has been fully hydrated. Thereafter, mixing of the cement binder will be carried out by one or more passes of the purpose made mixer until uniformity has been achieved. Water will be added as determined by the MCV results. Degree of pulverisation and MCV (OMC) will be monitored. Atfinal compaction the moisture content of the cohesive mixture shall not be less OMC determined in accordance with the 2.5 kg Proctor method of BS1924. Final compaction including finishing rolling will be completed within 2 hours of mixing of cement. On completion of final compaction, the surface layer shall be well closed, free from movement under the compaction plant and free from ridges, cracks and loose material. The full depth of the layer shall be compacted to an average density of 95% of the average fresh wet density.
GRANULAR SUB BASE
Each area of the site, building/yard/car park etc. will be finished with the correct depth of stone. The stone will be imported with 8 wheeled lorries and tipped and levelled as per the method of importing fill material. This will be laid and compacted then trimmed in preparation for the next trades. Measures will be taken to avoid contamination of the sub base with subsoil.
QA
As each area of work is completed, a hand-over sheet must be completed and signed by Winvicbefore any other subcontractors enter the area. For the stabilising activities the acting foreman in charge of the works will complete a daily diary. This will record details such as powders added, roller passes, weather conditions etc.
EMERGENCY RESPONSE
In the event of an emergency dial 999 immediately once safe to do so. Inform Winvic site management and if necessary make plant safe and walk to the fire point (as detailed in the site induction).
ENVIRONMENTAL RISKS
As an earthworks and stabilising contractor, we have a duty of care to protect the environment. The machinery and materials used can be very harmful if spillages and incidents are not dealt with accordingly. Always consult site supervisor if you are aware of any potential pollutant on-site.
ADDERS
It is believed that adders and many other potentially dangerous species of wildlife could be present on site. As an earthworks and stabilising contractor, we have a duty of care to protect the environment. Always consult your site supervisor if you are aware of any sightings of any rare or unexpected wildlife on-site.
Remember:

Snakes are cold blooded, they can often be found basking in warm locations
Adders are the only venomous snake native to Great Britain
On occasion, adders and other snakes may be found on construction sites
Adders are protected by law from beingkilled or injured.

Adders are relatively thick-bodied, and can grow upto 60–80cm long
Thecolour pattern varies, rangingfrom very light-coloured specimens with small incompletepatterningto individuals that are entirely dark and lack any apparent pattern
Most have some kind of zigzag dorsal pattern down the entire length of the body and tail.
Adders are venomous and bites can be painful, although rarely fatal. They are unlikely to bite unless they are alarmed or disturbed
Most bites occur from March-October
They are active duringthe day in the summer and hibernate in thewinter
Adders usually mate duringApril, and females give birth to live youngtypically in August/September.

Stop work near to the snake and report to a site supervisor.

Try to minimize disturbance. The creature should be left to move on its own accord and is likely to move on if disturbed.

Seek professional medical attention in the event of a bite.

Report any harm or injury that does occur to adders to a site supervisor.

Don’t

Injure or harm the snake or creature in any way…….this is illegal.

Handle adders or any potentially rare or dangerous wildlife…..leave to trained professionals.

REFUELLING PROCEDURE
The mobile plant operator will observe the correct procedure when refuelling plant, as follows;

The machine shall approach the refuelling station with care; assisted by a banksman when necessary
Adequate space should be maintained between the machine and refuelling point, ensuring space for the pump operator without being so far away that the hose becomes stretched or a trip hazard
The machine shall apply its parking breaks and the engine turned off; on level, firm ground
Secure the machines bonnet/hatch door to prevent it swinging shut
Remove the cap from the machines fuel tank
Turn on the generator when appropriate for refuelling station
Extend the hose and lock the hose nozzle into the fuel tank when possible
Begin refuelling the machine at an appropriate flow speed to prevent overfilling
The refuelling of machines should always be supervised throughout the whole process, despite automatic refuelling stations
Upon refuelling the machine, shake the nozzle into the machine fuel tank, cap the fuel tank and neatly place the hose back into the designated place after turning off the refuelling station generator
Inspect the machine and the ground around the refuelling point for spillages
All spillages must be contained and cleaned

WHEN REFUELLING, ENSURE:

No naked flames or reactive substances should be in the vicinity of the refuelling
Refuelling should be carried out in an outdoors or well ventilated area
Care should be taken when refuelling in wet weather as surface run off can cause the spread of contaminants

BASIC SPILL RESPONSE PLAN FOR FUELS & OILS

If possible, shut off the source of the spill immediately.
Inform your site manager to assist controlling the spillage.
Locate the spill kit - generally by the fuel bowser.
Use the absorbent pads or granules to help mop-up the spill. If the spill is too large for this, make every effort to contain the spill.
Cover/block any drains or channels to prevent the spillage entering a natural watercourse, stormwater system, sanitary system or septic tank.
If the spill is that great, inform the main contractor who will in turn contact an Emergency Response Agency.
Always wear the correct PPE whilst dealing with harmful substances and make sure any pads or granules used are disposed of as hazardous waste in a plastic bag.

DUST:
Environmental pollution will be kept to an absolute minimum and damping down will be carried out using a tractor and bowser as required by site conditions.Wind speed and direction will be monitored using a windsock when carrying out stabilisation works. Operations will be suspended in high winds.
WATER RUN OFF:
High levels of silt suspended in water can suffocate fish by clogging their gills, can remove essential oxygen from the water and can kill plants, animals and insects living in the water by stopping sunlight reaching them.
Surface run off on construction sites can be managed in a number of ways, to prevent the pollution of water courses and groundwater, including:

Drainage trenches to transport water
Creating sediment basins or fences
Provision of spillways/lined containers
Compaction of surfaces

IT IS ILLEGAL TO ALLOW SILT TO ENTER A WATERCOURSE OR DRAIN. Silt pollution spoils the appearance of watercourses, is easily traceable to the site from where it originated and in the past has been a major cause of PROSECUTION! We will only discharge silty water into adesignated settlement system.
When a site is water logged, water accumulates on the surface which is associated with several types of hazards and inconveniences:

Unsafe surfaces for vehicle traffic
The concealment of trip hazards on the ground or excavations
Aiding in the transportation of contaminated or polluted water
Hosting wildlife such as rats, exposing site operatives to disease
Halting progression of works
Erosion of surfaces
Pollution of watercourses
Reduction of stability and bearing capacity of excavations, slopes or cuttings

DEWATERING
A site may be dewatered with either a towed bowser or a pump. The correct procedure should be followed when dewatering a site to reduce the risk of the above hazards

Site operatives on the ground should wear waterproof overalls that should be removed and cleaned at the end of the work period
An appropriate machine should be chosen to tow the water bowser to prevent the vehicle from getting stuck and to ensure that the vehicle is capable of towing a water bowser at capacity in poor ground conditions.
Vehicles, pumps and people should be kept away from the edges of excavations and steep slopes
Vehicles should adhere to haul roads and flat surfaces
Vehicles should traffic the site slowly, with the operative wearing a seatbelt
Water collected via bowser or pump shall be stored for dust suppression or transported away from site by an appropriate party

TRAFFIC MANAGEMENT
Winvic will have a Traffic Management Plan for the site which will be explained in the site induction and displayed on information boards. Access on to the site will be via the main entrance which will be clearly identified. The Site Manager for Collins Earthworks will be involved in weekly site co-ordination meetings with Winvic in order to plan working zones with other sub-contractors. The Site Manager for Collins Earthworks will control all lorry movements for incoming and outgoing materials within our scope of works.
OCCUPATIONAL HEALTH
HEALTH SURVEILLANCE
All new employees of Collins Earthworks & Envirotrac must complete a health questionnaire and submit it to office staff prior to commencing any work. Employees must inform their line manager immediately if there is any deterioration of their health, or have been prescribed medication that may affect their ability to work safely. Employees that are in contact with harmful substances such as lime/cement/asbestos are to have periodic checks by a doctor.
MANUAL HANDLING:
Wherever possible, use mechanical lifting equipment to lift the load. If this isn’t possible then you must adopt good lifting techniques, consisting of bending up or down with the legs only whilst maintaining a straight back (ask supervisor for further guidance). DO NOT LIFT MORE THAN YOU ARE COMFORTABLE WITH.
NOISE:
Noise from construction activities may cause physical harm to workers and pedestrians hearing, as well as possibly harming ecosystems. The method of work chosen should cause minimum noise output where possible. The plant and equipment to be utilised for the work has been selected so as to keep the noise levels to an absolute minimum. However, should noise levels exceed 85dB(A) then appropriate hearing protection will become mandatory and be worn by all personnel within the vicinity of the works and the noise levels monitored on a regular basis. Site management should be aware of species present on or near the site that are vulnerable to excess noise.
VIBRATION:
Vibration can cause changes in tendons, muscles, bones and joints, and can affect the nervous system. Collectively, these effects are known as Hand-Arm Vibration Syndrome (HAVS). Plant and equipment (hand tools) to be utilised for the work operations is selected to keep workers’ exposure to vibration to an absolute minimum. Technical data on vibration levels for each item of plant or equipment is to be obtained and where exposure levels exceed 2.5m/s² on a regular basis, a programme of preventative measures and health surveillance is to be implemented. Time limits for daily usage of plant and equipment, are to be adhered to. Should any operative suffer from blanching, tingling or numbness of the fingers, or any problems with the muscles or joints of the hands and arms, they will stop work and report immediately to their supervisor.
