6. ACCESS AND EGRESS

Existing traffic use & restrictions:

ENSURE THAT A BANKSMAN OVERSEES ALL MOVEMENT OF SITE VEHICLES INTO THE SITE TO PROTECT THE SURROUNDING ENVIRONMENT

Access/Egress:-

The main entry point will be the point of entry to site for deliveries and disposal. Restrictions apply to the timing of vehicular access. No demolition traffic will arrive or leave site between 08.00 and 09.15 and 14.30-15.45.

The following controls will be initiated at the access/egress point to the carpark.

Particular care is to be afforded by all operatives and operators of plant when accessing / leaving site due to the continuity of the footpath which crosses this cross-over point.

Due to the nature of demolition and the waste produced, vehicles removing the waste will be of large nature – 20T tipper wagons, skip wagons or roll-on-roll-off container transports.

The frequency of these will vary throughout the demolition, but at the peak may reach 6 wagons per hour loading excavated debris.

These will be coordinated to avoid queuing on the highway.

A copy of the access / egress route and site contact telephone number will be held within the main office of contractor and faxed/emailed to any contractor engaged for the removal of materials or the supply of plant and machinery prior to movement taking place. This will ensure suitable warning is given to site and enable traffic movements to be pre-planned.

A banksman will be employed for movements of construction plant / vehicles across any cross over point and all drivers of construction traffic will adhere to the existing applicable speed restrictions.

These access gates will be kept closed with an operative assigned to oversee all movements. All other access gates will be locked and secured against trespass.

All works will be carried out by the use of hand tools in a controlled manner. Where necessary barrows/trolleys etc. will be utilized to prevent manual handling problems.

All soft strip materials will be removed from site progressively to prevent a build up of combustible materials via the insitu rear fire escape. Priority will be given, at all times, to others within the structure and assistance offered where required.

Loose fixtures & fittings i.e. cupboards; shelving;

These items will be removed by hand and removed systematically from the work area to the designated waste area for loading into skips for removal from the site. This will be carried out following the generation of a suitable amount of waste materials to prevent a build-up of combustible materials.

Care will be taken when removing abandoned waste to ensure sharp’s or chemical residues are not present. Suitable PPE will be worn for all works.

A manual handling assessment will be carried out before lifting larger items and where the risk cannot be adequately controlled the item will be broken up to aid movement/prevent injury etc.

Redundant heating units (overhead & wall mounted) and associated pipework; Electrical cabling & lighting units;

Prior to commencement of any of these removal works an assessment of the surrounding environment will be carried out. The following safety precautions will be carried out:-

Where items are at height:-

Where cast iron materials are involved:-

Where items are adjacent to asbestos products:-

Where flammable materials are sited within the vicinity

SAFE WORKING:

All works will be carried out in a methodical manner working back towards the main fire exit stairwell at all times. Pipework will be cut out using either quick-cut or hot cut methods or where risk of fire pipe cutters will be employed.

Cables to overhead heater units will be severed using cable cutters and the hanging brackets unbolted wherever possible or severed using Stihl saws.

Wall mounted heaters/radiators will be prised/dismantled from their fixings and carted from the work area. Associated pipework/cables will be removed in a methodical manner using cable cutters / Stihl Saws.

Lighting units will be have their cables severed and the units prized free from their fixings. All waste steelwork/pipework will be removed to the designated storage area.

Ceiling lining boards

Prior to commencement

Plasterboard ceiling panels will be prised from their fixings employing hand tools, any nail heads hammered into the timber frame and timber frame supports removed to provide a neat finish;

At no time will a section of plasterboard or gridwork be left partially removed / hanging as this can cause injury to operatives – make sure that the area is safe during the works and before shift end. Always bar off boards working from one end.

– do not work from the middle as the board can split and swing down causing injury.

Removal of Sanitary Ware

Confirmation of isolation of water supply to be obtained before commencement of these works.

These units will be removed carefully by either unscrewing fixings or where this is unsuitable, carefully breaking into surrounding brickwork to release. The individual units will be removed and placed within a designated storage area.

A temporary cement bung will be installed to drainage points to seal over to prevent cross contamination.

Associated pipework will be cut back (following confirmation of disconnection of supply via the Client) employing disc cutting equipment.

Remove Kitchen Fittings

Where items are at height:-

These items will be removed by hand and removed systematically from the work area to the designated waste storage area via either barrow or trolley transfer.

A manual handling assessment will be carried out before lifting larger items and where the risk cannot be adequately controlled the item will be broken up to aid movement/prevent injury etc.

Suitable PPE will be worn for all works. A temporary cement bung will be installed to drainage points to seal over to prevent cross contamination. Associated pipework will be cut back (following confirmation of disconnection of supply via the Client) employing disc cutting equipment.

Removal Of Doors/Skirting/Frames

Doors: Operatives will work in pairs for these works. The doors will be unscrewed from their fixings and carefully lowered to floor level before being moved to a designated skip.

Skirtings & Door Frames: Skirting will be removed first, followed by frames. All works to be carried out in a controlled manner – fixings will be carefully removed or prised using small tools. Two operatives are to be employed per frame to ensure full control is achieved.

Dismantling of Internal partitioning

All works will commence from the upper section employing hand tools. Prior to commencement suitable and sufficient PPE/RPE will be issued to include ½ face masks to P3 standard, disposable coveralls, goggles, gloves etc. See specific method for removal of MMMF materials.

Employing hand tools the operatives will commence with removing the plasterboard covering from the uppermost section to expose the MMMF materials behind – See specific method for removal of MMMF materials. To control dust release localized sprays of water will be applied as required and a polythene covering will be placed to the floor area to enable easier clearance of the waste and prevent double handling of the plaster which could lead to excessive dust within the atmosphere.

The timber support grid will be removed following removal of the partition covering by use of hand tools and size reduced for easier transportation. All protruding nails will be hammered over.

Removal Of Carpets / Linoleum

Operatives will, using hand tools, carefully prise carpets from their initial gripper strip. To minimize manual handling issues the section of carpet will be cut, employing Stanley knife, into manageable sections. The carpet will then be rolled as it is lifted and a further operative will remove all associated gripper strips to ensure safety of others within the area.

Removal of vinyl floor tiles (non-asbestos)

Where fungal deposits are noted these will be sprayed a minimum of 24 hr previously, with an application of fungicidal liquid.

One gang of operatives will be appointed to carry out these works.

The tiles will be lifted using suitable hand tools in as whole a section as possible.

Lifted tiles will immediately be placed within a wheel barrow and transported to the designated waste area to prevent tripping hazards for the further soft-strip works.

Removal of Ceramic floor tiles

NOTE: Ceramic materials are very sharp and can cause serious injury – ensure that the work area is controlled and only those allocated to the task are within the area;

One gang of operatives will be appointed to carry out these works and be issued with high impact goggles, gloves and instructed to untuck trousers from their boots (to prevent ceramic shards from entering their boots and causing injury).

The tiles will be removed employing a Kango breaker (under vibration permit system) with spade head with only one operator working to the area at a time to prevent ejection of shards causing injury to others. Once works are ceased or completed to the area a clearance operative will load the tiles/shards into a wheel barrow and transport to the designated waste area.

Removal of waste

All resultant arisings will be sorted, where necessary, removed from the work area and positioned either:-

Scrap – within designated waste skips for later removal;

Waste – combustible – within designated area to be loaded into either waste skips/rollon/off containers or flat-bed transport for removal to a suitable disposal point under Waste Management ‘Duty of Care’ procedures.

Environmental Monitoring

This will be carried out throughout the duration of the works.

When activities of a noisy nature or with high vibration potential are being carried out, monitoring will be carried out in line with BS:5228 Part 1 (Code of Practice for Noise and Vibration Control on Construction and Open Sites), to ensure that this stays within the prescribed parameters.

The site supervisor will carry out continuous monitoring with regard to dust and other disturbances.

Should works dictate, damping down procedures will be carried out during the demolition and loading operations to ensure migration of dust within the surrounding area is minimized.

Material located:

PREPARATORY WORKS:

All operatives involved with these works are to be instructed on the need to adopt a high hygiene standard i.e. wash at shift end, no smoking etc.

Due to the risk of inhalation of fibers, all operatives involved will be issued with and instructed to wear the following RPE/PPE:-

Disposable coveralls;

½ face P3 (high filtration) masks;

gloves;

goggles;

safety footwear.

REMOVAL PROCEDURE

To suppress fibre release the respective materials will be damped down by the use of an airless spray unit or similar.  Once damped the materials will be placed immediately into waste sacks to prevent double handling and sealed with cloth adhesive tape. Further operatives will then remove the sealed bags directly to the waste skip provided so as to maintain good housekeeping standards and prevent damage to the bags etc.

Safe Working; Operatives duties:-

Completion of Works; Operatives duties:-

Site Supervisors Duties:-

19.8 ENVIRONMENTAL ISSUES

Abandoned COSHH items throughout structures

Subcontractor to carry out a ‘sweep’ of all structures as part of site set-up.

Any items which are located are to be collected and placed within a secure area for removal from site via a specialist contractor.

Suitable PPE is to be worn during all collection activities – this will include as a minimum – impervious gloves; safety visor; overalls.

Where maneuvering onto pallets is required operatives will wear impervious gloves and coveralls ensuring that, before movement, each drum is inspected and tops secure.

Once placed onto a pallet the drums will be wrapped and banded to make secure.

The specialist contractor will collect and remove to the licensed disposal point under Section 62 Hazardous waste consignment note. A copy of this note will be provided to the site supervisor, as producer of the waste, prior to leaving site.

Consignment notes for all waste removal off site are to be provided for evidence as part of the SWMP;

Spillage Control

Spill kits are to be placed at sensitive zones i.e. adjacent to bunded fuel tank and drip trays used for any equipment/plant or COSHH items on site.

All spillages are to be controlled following TRD’s spillage procedure and any use of spill kits reported directly to the site supervisor for logging as per ISO internal requirements.

Previous Ground contamination issues

Subcontractor to adopt caution when breaking ground.

Continuous inspection of excavations is to be carried out and any signs of contamination relayed directly to the client for further investigation.

Consultation with the client will also be required to enable advise to be obtained as to how best to rectify the issue.

Works:

To be adopted where areas have determined the presence of hydro-carbon contamination – either within the ground investigation report or to new areas discovered as floor slabs are extracted.

Following excavation of highlighted areas contact with the clients representative is required to allow them to inspect the excavation prior to backfill therefore ensure that the engineer is aware of the works program to enable him to visit site and inspect.

The site supervisor will:

Once all preparatory works are in place and the machine & lorry are within their designated locations, works will commence with the careful extraction of contaminated soil from each highlighted area.

Care will be taken not to overfill the bucket attachment due to the risk of transferal of contaminated matter outside of the working zone.

Each bucket load will be lifted and deposited directly within the lined body of the lorry or onto the impervious liner– this will be repeated to designated depths as detailed by the client/report.

Once complete each excavation will be barriered off for safety until the Client/ engineer has inspected and confirmed that it may be backfilled. Clean inert arisings generated from the demolition works will be used as backfill back to surrounding levels.

Bats

The Bat presence/absence survey has found no evidence of roosting bats, hence no further survey or licence will be obtained. Measures will be taken to safeguard bats as identified in the Bat Method Statement.

Leptospirosis (Weil’s disease)

The leaflet from the HSE called “LEPTOSPIROSIS” – are you at risk! will be issued to each operative working on the project as will an employee handout detailing the symptoms etc. of coming into contact with Rat’s urine etc. Any flu-like symptoms must be reported to S Wright on on-set.

Hypodermic needle

Hypodermic needles and glue cans/bags may be contained within the site. A designated gang will be assigned to carry out these works prior to commencement of any further activities within the structure. Following completion of works a final inspection will be carried out by a competent person.

NOTE #1: BE AWARE THAT IT IS A KNOWN FACT THAT NEEDLES CAN BE TAPED TO BANISTERS, FURNITURE (WITHIN DRAWS AND TO BACKS) SO THAT WHEN YOU TOUCH/GO TO MOVE THEM YOU GET STICK INJURIES AND TO TOPS OF DOORS SO THAT THEY FALL WHEN YOU ENTER. IT HAS ALSO BEEN KNOWN THAT THEY ARE PLACED INTO SOFA CUSHIONS/MATTRESSES AS WELL AS BEING WITHIN ABANDONED WASTE / BED LINEN ETC. BE VERY AWARE – DO NOT TOUCH ITEMS WITH YOUR HANDS – USE LONG HANDLED TOOLS UNTIL YOU ARE SATISFIED THAT THERE IS NO DANGER AND ALWAYS WEAR PPE, EVEN WHERE YOU ARE SATISFIED THAT THE ITEM IS SAFE TO HANDLE;

NOTE #2: ENSURE THAT CORRECT PPE IS WORN AT ALL TIMES. DO NOT TUCK YOUR TROUSERS INTO YOUR BOOTS, WEAR THEM OVER TO PREVENT RISK OF ENTRY BY NEEDLES;

Works:

All operatives will be made aware of the above facts during specific on-site induction/toolbox talk and instructed in the need to maintain vigilance and adopt caution when handling abandoned waste.

Each operative will be issued with ‘Anti-sharp’ gloves; ‘Anti-sharp’ leggings; safety boots; safety helmet and instructed to wear same. ‘Litter picking’ hand tools will also be issued to ensure that no contact is necessary with the operatives person.

The operatives will then systematically go through each area of the structure (including external landings/stores/garages etc.) moving abandoned waste/bedding, furniture etc. to inspect same.

All hypodermic needles will be picked up via the ‘litter picking’ equipment – pick up by the blunt end (or the syringe if still attached) and placed directly into a Sharp Bin as provided to each operative. All bags/cans etc. will be picked up, again using the ‘litter picking’ equipment as before.

At the end of shift all contaminated material packaging will be suitably sealed and placed within a secure area as instructed by the Site supervisor. All full sharp bins will be returned to the local drug rehabilitation office / local authority or via Wards (as appropriate – liaise with environmental manager) for disposal by incineration.

All glue-associated items will be disposed of at the appropriate site.

ACTION IN THE EVENT OF AN INJURY:

Hepatitis and the virus HIV can be contracted by a puncture wound from a blood contaminated ‘sharp’.

Needles carrying the greater risk and blood contaminated razors and broken glass to a lesser degree.

If a cut or puncture wound is received encourage free bleeding immediately. This is done by squeezing the area around the wound to force out a flow of blood;

wash the area;

– report immediately to your site supervisor who will ensure that you attend the A&E dept. of the local hospital

– Any injury of this type MUST be recorded in the site accident book;

– the safety officer is to be informed immediately

Prevention of contamination & sealing of drains

Protection of surface water courses

Surface water courses will be suitably protected against runoff and associated particulate materials or dissolved materials. Protection will be provided in the form of cut off trenches, pumped bunds or interceptors sand bags or similar precautions.

In protection of water course, due attention will be paid to the “Pollution Prevention Guidelines” published by the Environment Agency. PPG5 (Works near or liable to affect water courses) and PPG6 Working at Construction and Demolition Sites are especially relevant.

Odour dust and nuisance (not including noise)

All works will be undertaken in accordance with the contract specification.

No special precautions against inhalation or contact of site personnel with ground materials will be taken on the site other than those normally undertaken in accordance with good site practice.

This should include as a minimum use of overalls, boots and gloves with a change facility for clothes for travel to and from the site. Obvious signs of visual contamination will be assessed if they occur.

It is considered that the ground materials to be encountered will be sufficiently coherent not to pose a significant dust generation hazard. In the event of dust becoming a problem, suitable damping down will be carried out to contain the hazard.

Dust generation from operations related to demolition of buildings or removal of hardstandings may be a greater potential hazard. This will be handled by suitable damping down procedures which in turn will be continually monitored.

Protection of other site users and off site personnel.

The site is currently unoccupied and no special measures are required to protect on-site users.

However, adjacent sites are operational and there are public access routes immediately adjacent all site elevations. Measures will be taken to protect such off site personnel against hazards associated with the works.

These will include, but not necessarily confined to:-

EQUIPMENT/MATERIALS

Floor Tile Scrapers Hand Tools

Hand Held spray unit

Wetting Agent

Asbestos Waste Sacks

Assessment: The work consists of the removal of an asbestos based product known to contain chrysotile asbestos. The floor tiles are thermoplastic therefore it is anticipated that the control limit will not be exceeded. For this reason FFP3 half-face respirators will be used along with disposable coveralls.

In some areas the tiles are non-asbestos but the bitumen adhesive contains Chrysotile asbestos.

Work Method:

Access will be restricted to operatives involved in the work by means of warning tape and notices.

Having donned their correct PPE/RPE the operatives will commence with the stripping operations.

Utilizing the tile scrapers the operatives will carry out lifting of the tiles whilst a further operative carries out localized spray of wetting agent to the disturbed area to contain any fibre release.

The lifted tiles will, where identified as containing asbestos, then be bagged and swan- neck tied with cloth adhesive tape before being removed to the designated special waste skip.

Hand tools will be utilized to scrape up the fixing glue residue or specialist environmental solvent type liquid applied to dissolve the adhesive.

This residue will be placed into asbestos waste sacks for disposal.

Each sack will be swan neck tied to seal and double bagged and sealed once more with cloth adhesive tape before transportation off site under Section 62 hazardous waste consignment note.

19.10 DEMOLITION PROCEDURE

 Background info:

NOTE #1: THERE ARE NUMEROUS RESIDENTIAL DWELLINGS IN CLOSE PROXIMITY TO THE SITE, WHICH WILL BE OCCUPIED, LOCATED ADJACENT TO THE SITE BOUNDARIES – A DIRECT LINE OF COMMUNICATION WILL BE MADE AVAILABLE DIRECT WITH THE OCCUPANTS AND SUITABLE TIMES AGREED IN WHICH TO CARRY OUT DEMOLITION OF THE SENSITIVE AREA – THE SUPERVISOR WILL SPEAK WITH EACH OCCUPANT AND PROVIDE HIS CONTACT TELEPHONE NUMBER ETC. AND AGREE WHAT PREPARATORY WORKS ARE REQUIRED WITH REGARDS TO ADDITIONAL SAFETY MEASURES ETC.

NOTE #2: WHERE CONTROLLED DEMOLITION WORKS ARE REQUIRED WHERE THERE IS RISK OF INTERACTION WITH OTHERS THE SITE SUPERVISOR WILL APPOINT BANKSMEN AT DESIGNATED POINTS. WORKING FROM WITHIN THE FOOTPRINT OF THE BUILDING THE ELEVATIONS WILL BE DEMOLISHED IN A CONTROLLED MANNER WITH ALL BRICKWORK BROUGHT INTO THE FOOTPRINT AT ALL TIMES AWAY FROM THE HIGH RISK AREA. SUCH AREAS WILL BE CARRIED OUT AT ‘QUIET TIMES’ FOLLOWING CONSULTATION WITH THE APPROPRIATE AFFECTED PARTIES.

PREPARATORY WORKS:-

Careful inspection of each structure will be carried out by the site supervisor and the appointed machine operator. All sensitive areas will be highlighted to the operatives and Toolbox talk given to ensure the correct safety measures to be incorporated are known by all persons.

The site supervisor will make contact with all neighboring representatives who will be affected by the works to ensure they are aware.

During all works the surrounding area will be classed as an exclusion zone. Works will be programmed so as not to coincide with peak-times.

Once the designated section of structure is ready for demolition and the site supervisor gives the instruction, all operatives not involved with the works will position themselves at the designated safety zone unless appointed as banksman whereby they will position themselves within their designated view point.

On completion of all preparatory works i.e. hypodermic needle clearance / soft-strip and asbestos removal operations demolition works will be carried out.

Demolition Works:

Mechanical:

The mechanical reduction works will be from top down with the demolition machine with PD19 attachment reaching in to its furthest point at the top level and staggering the cut lower down to produce a natural run off of materials, so far as is reasonably practical. In this way overloading of each floor level shall be reduced to its lowest expectation.

The reduction of the structure shall be progressive working a bay at a time. As each section is demolished, the debris shall be pulled off to prevent any possibility of a build up of materials.

This reduction process shall be continuous in a progressive and systematic manner. During all reduction operations, the machine operator, together with his supervisor, shall continuously asses the integrity of each section of the structure being reduced at that time. Where any ambiguity exists as to the continued integrity of any adjacent section the works are to suspended and an action plan formulated to deal with any potential problem.

During all structural reduction operations, the operator of the demolition rig will leave sufficient bracing to maintain stability allowing him to carefully reduce the building elements in a piecemeal manner.

Throughout the duration of the works, all operatives shall be aware of and shall carry out any instructions regarding the safety and integrity of the surrounding environment. Works considered to have a significant impact on the environment shall not be implemented until such time as suitable and sufficient control measures have been put into place to reduce such impacts.

Noise and dust levels are to be kept to the lowest expectancy. Operations shall be carried out using power fork or grapple wherever possible.

All resultant arisings will be sorted and removed from the work area and all deleterious materials loaded into either rollon/off containers or tipper transport for removal to a licensed disposal point under Waste Management ‘Duty of Care’ procedures.

Completion Works:

Once at slab level and arisings removed an inspection will be carried out.

The excavator will initially break along predetermined lines employing concrete breaker then, to reduce noise issues utilize the bucket attachment to lift the slab in sections – an assessment will then take place to ascertain whether these slab sections can be loaded direct or further size reduction is required.

At no time will works be carried out which may affect the adjacent pavings etc.

All materials will be sorted and arisings removed from site.

Once removed the exposed footings will be grubbed up and once all arisings cleared the ground will be made good – compacted and graded to existing paving levels with suitable topsoil.

Environmental Monitoring

This will be carried out throughout the duration of the works. When activities of a noisy nature or with high vibration potential are being carried out, monitoring will be carried out in line with BS:5228 Part 1 (Code of Practice for Noise and Vibration Control on Construction and Open Sites), to ensure that this stays within the prescribed parameters.

The site supervisor will carry out continuous monitoring with regard to dust and other disturbances.

Should works dictate, damping down procedures will be carried out during the demolition and loading operations to ensure migration of dust within the surrounding area is minimized.
