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:
- Ensure the area is pre-marked to ensure that all materials containing contaminants are removed;
- Advise the Client/Engineer of the program of works;
- Designate the working zone and where materials to be removed from site – position the lorry to a safe point immediately adjacent the excavation point to enable the material to be deposited directly into the skip to prevent distribution of the material outside of the controlled zone. Where items are required to be further investigated/tested an impervious sheeting will be positioned to a designated area and the excavated materials deposited on this until instruction received as to the required treatment/removal from the client;
- Designate the area as a `flame-free zone` and no smoking zone
- Carry out specific Tool Box talks to all operatives on site.
- Ensure that the excavation is made safe until such time as the Client/ engineer has inspected and OK’d for backfill with clean inert materials;
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
- First task will be to identify all drain runs on the site – Foul & Surface Water;
- Carry out site survey to identify location/condition of all man-holes;
- Open up each manhole and check the direction of flow – mark on site drawing;
- For those manholes located adjacent to the site boundary/ feeding retained areas – insert temporary plug at drain outlet;
- Following commencement of demolition works on site each drain run will be severed at the site of the manhole;
- A permanent cement mortar plug will then be forced within each manhole, consisting of a 3 to 1 mortar
- Each sealed manhole will be clearly marked on the site plan for inclusion in the site safety file;
- Operatives gaining access to any manhole shall be trained in the correct entry / rescue procedures for confined spaces and be supervised at all times – a permit to enter system will be in operation;
- Once manholes are suitably sealed then manhole covers will be paint marked for identification
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:-
- correct fencing off of the site and all appropriate security measures,
- avoidance of wind borne dust,
- reduction to the lowest level of noise (including that from site traffic and other machines)- this will be monitored 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.
- use of wheel washes and wash down of vehicles prior to leaving site whenever practical,
- correct sheeting of containers or vehicles containing contaminated materials before leaving site,
- erection of full public protection measures to all elevations which impede on surrounding pavements / car parks
- Installation of suitable and sufficient traffic / pedestrian signage in line with the Road & Street works Act 1991

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.
