Introduction-Method Statement for Demolition Works
This method statement for demolition works of the building describes the activities such as soft stripping, scaffold erection, demolition, foundation/hard standing removal, and crushing to a certified 6F2 aggregate as detailed for the agreed-upon works at the site.
The facility is surrounded by its own perimeter fence. The existing gateway on the site’s southwest corner provides access to the site.
A double wood gate made of timber hoarding will serve as the entryway. Parking is extremely limited on-site and is strongly discouraged.
Visitors should call beforehand before coming to the site because site logistics are subject to change as the work progresses.
This method statement falls under the category of civil works.
Site Restrictions
On-site, the constraints described below were identified. All of these will be evaluated separately and the necessary controls implemented.
Unidentified Asbestos Containing Materials (ACM’s) in the building’s south elevation close to boundary fencing (vigilance taken when dismantling).
Communication
The major contractor will be in charge of communications with the client. However, the guidelines below shall be followed to guarantee that the site leaves a positive impression.
Local residents will be given the site manager’s contact information. The contractor is aware that pollution and dust migration are concerns with this project because of its close proximity to businesses and residents.
Any pollution or dust/particle movement from the site will be avoided as much as possible. The contractor shall keep a system on-site for recording any occurrences and any corrective actions done.
It is suggested that a newsletter be distributed to local residents and posted in prominent spots throughout the property. This will include site contact information, a work schedule, and any planned projects that may cause disruption.
If a neighbor or a member of the public makes a complaint about site activities, they will be provided with the site manager’s contact information.
If complaints concerning odor, noise, dust, or vibration are received, they will be addressed immediately so that results obtained at the time of the complaint can be analyzed and, if necessary, prompt actions are taken to correct the situation.
When a valid grievance is raised, steps will be taken to prevent the complaint from recurring.
When a complaint is received, the contractor will tell the client as quickly as possible and advise them of the activities taken to resolve it.
Work Description
The scope of work is stated below. In this section of the demolition method statement, each thing will be specifically mentioned:
- Soft stripping
- Erection of scaffolding
- Ramp separation works
- Demolition of ramps
- Demolition of major structures
- Down to 2m, removal of foundations
- Crush concrete/masonry to certified 6F2 and leave on site by stockpiling
5. Site Logistics, Egress, and Access
The contractor is aware of the site’s limits and will implement a logistics regime to deal with them in such a way that the effects on neighboring roadways and the general public are minimal and that their safety remains paramount.
Because there is limited space on-site for construction vehicles, a detailed traffic management strategy is essential for the site’s successful operation.
Vehicle drivers must follow the traffic plan and the traffic marshall’s orders at all times. All cars accessing the site will be limited to 5 mph.
A car will not be allowed to reverse without the presence of a traffic marshall. All drivers must follow all traffic regulations and be courteous to their neighbors.
The vehicles will be directed to exit the site by traffic marshalls, who will then turn left into the main road.
Hoarding
The contractor will construct the site hoarding.
This hoarding will be classified as temporary work.
It is their job as the principal contractor to ensure that the hoarding is in good working order. The client will be alerted immediately if the hoarding is found to be inadequate or in bad condition will be alerted immediately if the hoarding is found to be inadequate or in bad condition.
Statutory signages will be displayed around the outside of the perimeter of the hoarding. These signs serve as a warning to possible intruders and a deterrent to children playing on the property.
Facilities for Welfare
The contractor will provide and maintain welfare facilities, which will be located at a suitable location on the site away from the demolition work.
The smoke-free (premises and enforcement) regulations should be implemented in addition to the construction (design and management) regulations.
The following should be included in the site welfare, including female facilities. A sufficient number of sanitary facilities, proportional to the number of people working on the site, are well-ventilated and lit.
Washing stations with basins large enough for individuals to wash their faces, hands, and forearms, as well as a supply of clean hot and cold, or warm water.
Rooms with laundry facilities will be properly ventilated and illuminated. Changing and storing clothes. Drinking water and drinking vessels in sufficient quantities.
Any problems with the welfare must be reported as soon as possible to the site manager.
Methodology Outline
Existing Services Isolations, Temporary Electrics
Prior to beginning work on-site, we must get proof that the existing services have been disconnected. This will be accomplished through a disconnection certification for the known services. The local water supplier will license a metered hydrant to meet the requirements for dust suppression during demolition.
Any unused foul and surface water drains within the project boundary will need to be permanently sealed, either with a bung and/or concrete.
An onsite inspection should be performed to guarantee that no drain runs from adjacent properties enter the work area.
Asbestos Removal
From the completed survey, no asbestos-containing materials (ACMs) were discovered within the buildings.
All contractor operatives have been trained to recognize ACMs; if any ACMs are discovered during demolition, work will be halted and the Site Manager notified; an asbestos surveyor will be summoned to the site, and a sample will be taken for testing to confirm the presence of ACMs before work in that area can resume.
Prior to the start of their job, they will produce a thorough and precise asbestos removal method statement.
The asbestos-containing materials will be removed as far as is reasonably feasible by fully trained and experienced demolition operatives using the techniques indicated in the Health and Safety Executive document HSG 189/2 & L27 work with asbestos, which does not generally require a license.
Hazardous Substances Removal and Disposal
Unidentified cylinders, drums, and containers will be collected and checked for contamination before being transported and kept in a secure facility on site.
One of our professional subcontractors will then remove and properly dispose of all COSHH compounds offsite.
The type, quantity, and disposal address of COSHH objects removed offsite will be documented on hazardous waste consignment notes.
If any storage containers near the site boundary contain liquids, a trained trash collector will analyze them and remove them.
They’ll pump the liquid out and transport it to a treatment facility. Any hazardous liquid discovered on site will be handled with extreme caution.
On-site spill kits will be supplied, and personnel will be trained in their use. A hazardous waste notice will be written for any hazardous compounds taken from the site.
Soft Stripping Works
Before the serious demolition work begins, all of the objects listed below will be removed from the structure. On the floors, the materials will be stripped of their fasteners and sorted into their many waste streams.
The materials will be delivered to external windows through wheelie bins and then loaded out of the windows into bins outside the building.
Around the dumpsters, exclusion zones will be created with caution signage alerting people to the drop zone. They will then be sent to the nearest recycling center.
Mattocks/hammers, 110v reciprocating saws, abrasive wheels, pinch bars, steps/podiums, battery-powered drills, and oxy-propane cutting equipment are some of the items that will be used.
The ‘Hot Works’ permit system will cover all tools and equipment that fall within the category of hot work.
Fixtures and Accessories
Any remaining loose fixtures and fittings will be removed from the building in their entirety, carried to the loading area by hand, and loaded directly into the waiting waste skips. Larger elements will be dismantled/downsized using small tools, reduced into manageable-sized sections, and transported to the disposal point.
Suspended Ceilings
Any suspended ceilings will be removed using a mobile scaffold tower or podium stairs, and tiles will be lifted and twisted from the suspension system and dropped to the ground, where they will be bundled and loaded into the rubbish skip on a regular basis.
The suspension system will be dismantled as tiles are removed and supports are cut with croppers, and the system will be placed into a rubbish skip.
Skirting, Doors, and Door Frames
Using pinch bars and hammers, employees will remove door frames and skirting. The pieces will be gradually prised free from their fixings, any obtrusions and nails will be removed or hammered over, and all leftover materials will be carried for disposal.
Doors will be removed by operatives who will take off the door furnishings before prying the door from its hinges with pinch bars and mattocks. Doors will then be resized for disposal or carried whole to the disposal location.
Partition Walls
Using appropriate handheld tools such as pinch bars, picks, and hammers, the operatives must remove any stud partitioning.
Using hammers and pinch bars, remove the wall structure by removing the covers.
The remaining stud work should be pulled free and de-nailed or have nails hammered over once exposed.
The resulting waste must be transferred to the loading area.
Flooring Covers
The operatives will use mattock picks and shovels to remove the wooden floor coverings.
Carpet tiles and vinyl floor tiles should simply be prised up using hand tools, then packaged and taped before being taken to a disposal location.
Carpets that are rollable will be cut into strips while still in place and rolled up for collection in strips, which will then be transported to the disposal location.
Windows/Glass Units
Wherever possible, glass units and/or windows will be removed as whole units, an exclusion zone/crash deck will be used as needed, and operatives will be wearing hard hats, safety boots, gloves, and eyewear.
The glass will be handled with due care and disposed of in a secure way in skips.
Tubes fluorescent
Any fluorescent tubes that are necessary to be removed will be removed as if they were being replaced, with bulbs collected and placed into a specific waste coffin, which will be stored on-site during soft strip works and then removed as specialist garbage after all bulbs have been removed.
Furthermore, any abandoned, unlabeled cylinders/drums/containers will be gathered and tested for contamination before being transported to a fenced-off storage area on-site with COSHH items being collected once the buildings have been evacuated by a specialized waste sub-contractor.
Ground-floor soft strip materials will be taken outside of the building and dumped in their various waste streams.
The arisings from the ground floor can be removed with a Bobcat.
At all times, operators and machinery must be kept apart. The individual heaps will be loaded into respective bins by an excavator with a selection grab.
The bins will be collected and sent to the proper recycling center once they are full. As seen below, materials from the top floors will be removed from the structure.
Erection of Scaffolds
It is proposed to install a completely boarded scaffold to help protect people traveling along the walkway during the demolition of the property’s southern elevation.
The scaffold will extend up to 2m above the demolition point before returning to the next height (where possible)
As an additional safety measure, diagonal bracing will be installed with the scaffold.
The scaffolding contractor will design the exact quantity and specification of the bracing.
Box ties and Hilti ties will be used to secure the scaffold to the building’s façade. The Hilti ties are drilled into the building’s facade.
The box ties will enter via the windows and be secured around the columns between the windows.
The scaffolding contractor will supply the full details of all the ties utilized as a part of the scaffold design.
The scaffold will be struck to suit the progress of the demolition. During the demolition, scaffolders will be present to ensure that no scaffold is left standing for an extended period of time (overnight or on weekends).
Enough ties must be left in place to keep the remaining scaffold tight when the scaffold is gradually struck.
All scaffolding must be supplied, constructed, and disassembled in compliance with applicable laws and regulations (TG20). Before it is utilized for the first time, all scaffolding will be examined, and then every 7 days until it is removed.
It will also be inspected if it is exposed to situations that are likely to cause degradation, such as after severe weather or a significant change.
All scaffolding inspections will be conducted by a competent person with the appropriate combination of knowledge, training, and experience for the kind and complexity of the scaffold to be inspected, and a visible tag system will be used to complement inspection records.
The Construction Industry Scaffolders Registration Scheme (CISRS) may have assessed competence, or an individual may have sufficient scaffolding experience and acquired further training under a recognized manufacturer/supplier scheme for the specific configuration he is examining.
Prior to the start of the erection, the scaffolding contractor will give a complete scaffold design.
Demolition of Ramps
The ramp must be detached from the main building before the main structure may be dismantled.
A demolition machine with a concrete chomping attachment will finish the job. The ramp, as well as all connected elements, will be removed and disposed of.
To control the dust, an operative with a water hose will be deployed. All of the concrete scraps will be stored and crushed to 6F2 later.
All other rubbish must be sorted and deposited in the appropriate waste skip.
Demolition by Machine
After the ramp has been dismantled, the main building will be demolished. The demolition will take place from northeast to southwest. The building will be searched for potential intruders and the exterior doors will be sealed shut to prevent individuals from entering during the demolition process.
An excavator equipped with a chewing attachment will conclude the destruction.
The machine will try to get as close to the main structure as possible. An operative will use a water hose to achieve dust suppression.
The operative will be positioned away from the machine and any falling debris. An exclusion zone will be set up around the machine or location that will be dismantled, with warning signs posted.
As the demolition process progresses, this will be gradually shifted. After that, the operator will pull the concrete panels away from the concrete columns, letting the arisings fall to the ground.
The debris from the demolition will be used to raise the main structure. These will be stacked in the form of a platform, allowing the machine to work from a level and stable posture.
The machine will then munch through the concrete beams and columns after the concrete panels have been removed.
This will be munched on either end, or the column/beam will be lowered to the floor and processed by a smaller machine following the final cut.
Hydraulic breakers are preferred over munching attachments because they produce significantly less noise and vibration. As a result, there is less inconvenience to nearby residents and businesses.
The scaffolding along the south elevation will be progressivity struck when the columns and beams are removed.
The scaffold will be extended 2m above and 2m beyond the demolition point. Water will be used to control dust during the demolition and materials processing.
Behind a Herras exclusion zone, a banksman will be stationed at a safe distance from the point of demolition.
After the building has been reduced to the ground floor, any projecting rebar will be cut flush.
These columns’ foundations will be removed at a later date. The debris from the demolition will be stockpiled for the crusher.
The stockpile must be tidy and devoid of trash. The cleaner the stockpile, the cleaner the aggregate after it has gone through the crusher.
Removal of the slab, footings, and foundations
Once the building has been reduced to the ground level, the slabs will be removed. A pneumatic breaker will be used to break the slab first. The slab should be lifted up using the excavator bucket whenever possible.
The pneumatic breaker’s noise will be reduced as a result of this. The footings across the building’s footprint, as well as all the hardstands that make up the site, will be removed.
The stability of the border fencing must never be jeopardized. Because of its proximity to a pedestrian foot route outside the site boundary, the footing along the south elevation of the structure must be left in place.
Crushing to 6F2
All concrete and masonry leftover from demolition and foundation removal will be crushed to a certified 6F2 grade.
The crusher will be placed in an appropriate location on the property, away from any boundaries or adjacent properties.
The client must agree on the position of the crushed debris so that it does not cause a hindrance during construction.
To control dust at both ends of the operation, there must be a sufficient water supply adjacent to the crushing works.
One excavator will be stationed on the concrete arisings, gradually filling the hopper, while the other clears the belt and heaps up the 6F2.
To protect people from being injured by the debris that the crusher extracts, an exclusion zone must be constructed near the magnetic belts of the crusher.
An operative must never be near the crusher while it is operating. Only when the machine has been turned off may the operative access it.
Environmental Factors to Consider in Method Statement for Demolition
Noise will be reduced by the use of a modern, silent plant, noise monitoring equipment will be used in sensitive locations as needed, and employees, contractors, and visitors will be required to wear hearing protection in any designated hearing protection zones (these will be identified by the relevant signage).
Dust will be reduced by using water spray (as needed). During construction, all reasonable efforts will be taken to avoid soil from being deposited on the site access road and the main road.
The following are examples of such measures:
Good on-site housekeeping
The use of the most recent low-vibration plant available in the industry for the task will be employed to lower the number of noise emissions from machinery as far as reasonably practicable for effective traffic management control of vibration.
Fire Plan
Before work begins, a fire and emergency plan, as well as a risk assessment, must be in place and all employees and visitors must be initiated.
The contractor is responsible for developing and implementing this. We must also follow the procedures listed below.
On-site fire extinguishers suitable for various sorts of fires should be accessible. To cover any hot work, a permit-to-work procedure must be in place.
Hot work must stop at least one hour before the conclusion of the shift to allow for fire watch.
First Aid
First aid must be provided as per the Health and Safety (First-Aid) Regulations 1981 and must be available prior to the start of any work on the site.
This should consist of:
A sufficient number of first responders are present.
The first-aid kit is fully stocked.
Station for cleaning the eyes.
Up-to-date first-aid training certifications
A book of accident reports (will be located in the site office).
Site First Aiders and First Aid Box location signs must be put across the construction site.
Risks and Controls-Demolition Method Statement
Risk is evaluated using the HSE’s Guidance Note INDG16 “Five Steps to Risk Assessment” as follows:
Look for potential dangers.
Determine who might be hurt and in what way.
Assess the risk and determine what controls are necessary.
Keep track of your discoveries.
Review the assessment and make any necessary revisions.
For a contract like this, we evaluate health and safety, COSHH, and the environment individually. Before any work begins, a comprehensive risk assessment will be conducted. The following are the risk and control measures for the project:
Fire
After usage, gas bottles will be tied to a specialized trolley and stored in a cage. The location of the gas storage cage should be recorded on the site plan, which should be visible to the fire department in the case of a site fire.
The bottle storage area will be adjacent to the Fire Point.
A Hot Works Permit is required for any hot job.
Interaction with the public: full-time Traffic Marshals will control access and egress.
Demolition Managers/Supervisors will oversee the entire project.
All plant workers must be competent and trained, and they must have CPCS/CITB certification.
The contractor will check qualifications prior to beginning work, and copies will be kept in the site file for future reference.
All workers must be competently trained and CSCS/CCDO certified. All workers must wear adequate personal protective equipment.
Where necessary, exclusion zones with proper signs shall be created.
Fine water spray will be used to control dust as needed.
In accordance with the Site Establishment Plan, pedestrian routing will be established and maintained.
Gatemen to oversee vehicular entry and exit to and from the premises.
The site-specific evaluations will be kept in the site manager’s file and will be made site-specific by the site supervisor for the specific work activity being carried out and the chemicals to be utilized on the site.
