Determining the Demolition Methods

Demolitions plans usually illustrate the sequence of demolitions and identify the destruction method that works for the structure with minimal environmental impact. Depending on the construction materials, the demolition company can use non-explosive methods, which use hand tools or machinery, and robotic demolition by employing electric excavators. Some of the non-explosive methods include:

Soft strip: The demolition relies on hand tools to strip off floor coverings, ceilings, lifts, doors, and partitions methodically. The disposal also relies on waste chutes and lifts before carrying the waste out of the site using bins.

High-reach demolition: It uses different types of excavators to raze down a building. High-reach machines are for tall buildings, but a standard machine can take over in the lower levels.

Deconstruction: For panel buildings and tower blocks built with large concrete panels, the contractor uses cranes to remove the panels in reverse order. However, it needs support to ensure it does not collapse during deconstruction.

Explosive demolition uses explosives to remove the foundation of the building, and the entire structure will collapse. Here are some standard methods of explosive demolition depending on how the building collapses:

Falling like a tree: If the house has a significant distance from other buildings in the area, demolishing the house sideways is the best option. The contractor will place the explosives on the lower levels and uses cables to control the direction of the fall.

Falling into footprint: If there is limited space, the contractor can set the explosives in the middle of the building to ensure it implodes on its footprint.

Safety Measures

The demolition plan must stipulate the safety measures in place to protect the contractors and the environment. For instance, there should be strategies to reduce and monitor noise, dust, and vibrations. Fire and emergency plans should be comprehensive and included in the health and safety induction.

Conclusion

When a building becomes uninhabitable, do not worry about the details required for demolition. Instead, hire a demolition company, and they will take care of all the legal documents and work. This protects your neighbours and the environment from pollution and unnecessary disruptions caused by the deconstruction process.

Due to the severity of the illness, many demolition companies are taking steps to reduce the risks in their workplaces by making changes such as getting air purifiers and providing their workers with even more personal protective equipment. This will make it easier on employees who have already been infected with COVID-19 as they will be able to work without worrying about being exposed. These measures may help companies find a way around facing any adverse consequences due to side effects from the virus and help them keep their contracts running smoothly.

Demolition companies need sufficient qualified people with experience and expertise to carry out the work required in this industry. The situation is becoming very frustrating for everyone involved, and there’s no way of knowing how long it will last or what other complications from the virus could surface further down the road.

It is important for everyone to proceed with caution when dealing with COVID-19, construction and demolition companies will need to find ways around the disruption whilst taking all measures necessary to reduce risks in their workplace.

In terms of the roof demolition work itself, it’s usually the safest and most practical approach to start from the top and work down the roof space. Once you have removed several rows of material, take down the tarpaper or other underlying material in a steady way that avoids tearing or leaving you with thousands of tiny pieces clear up. Again, the use of specialist demolition tools will give you the best chance of doing the job both efficiently and with the least amount of clean-up work afterwards. When it comes to larger structural elements such as roof trusses or frames then it will almost certainly require a specialist tradesman or demolition company to carry out the work.

If you are in any doubt whatsoever about roof work, contact professional tradesmen; there are lots of London demolition contractors able to carry out this work. Regional areas may have specialist companies who work with materials and construction unique to that area – for example, demolition in Kent can take account of the unusual oast house structures as well as more traditional buildings.

Chimney demolition costs will vary depending on the size of the chimney, is it residential, commercial, or an industrial chimney demolition job? Are the floors it occupies in a multi-storey building and what is its attachment to the building?

Expect to pay more if your chimney is part of the structure or foundation of your house. Most demolition contractors will factor in the cost of removing the chimney stack, chimney breast and rectifying the resulting gaps left behind.

You will also purchase materials to patch up the holes and match the interior design with the rest of the house. If your home needs framing adjustments and foundation work, the expenses may start to increase.

Chimney demolition is a significant structural change to a building or structure. This means you need to adhere to the structural guidance and legal framework provided by building regulations; local authorities may declare your project impractical and illegal. To ensure you comply with the regulations, contact the local authorities and building control departments to get the relevant permissions before work begins. A building or demolition contractor can help you expedite the process as they will be familiar with the requirements and rules.

Getting the right building permissions is necessary to prevent future complications with surveyors when you come to sell the property. You should also consider party wall agreements to avoid additional charges for rectifying any discrepancies caused. Other legal considerations include restrictions provided in conservation zones and listed buildings.

In most industrial chimney removals, the contractors utilise explosive demolition instead of removing the structural framework systematically. Such demolition methods may require planning permission, including a detailed plan to seal the resulting hole and dispose of the demolition waste.

Residential chimney demolition should not be considered a DIY project, it is always advisable to seek professional assistance to avoid causing structural damage to your home.

Besides, professional demolition experts are likely to make the process less invasive and complete the project faster.

Other Buildings

Certain development rights permit contractors to demolish the whole build without planning permission, however, you need to seek approval of the demolition method beforehand. Some of the exceptions to the rule include:

– Demolishing buildings that are uninhabitable due to neglect or deliberate action. If the building requires a few repairs to make it safe, you will need planning permission to demolish the structure.

– Drinking establishments like pubs require planning permission before demolition, especially in the Asset of Community Value database.

– Concert halls and venues for live music performances also require permission for demolition.

If a building’s urgent demolition is necessary due to health and safety concerns, then a demolition company does not have to comply with the approval process, however, they must provide written justification.

Demolishing Parts of a Building

Permitted development rights are invalid when you are demolishing parts of a building since you are making structural alterations, this can also be referred to as a partial strip out work in the demolition industry. Therefore, you need planning permission from the local authorities to demolish parts of a building.

When planning any demolition project, it is advised checking beforehand if you need actual planning permission. You should also confirm if you need other consents before starting any work.

Additional consents include Part Wall Act notices and building regulations approval, among others. Some buildings also require an environmental impact assessment before demolition work can start, which necessitates planning permission.

In summary, this article should only be used as a guide, it is crucial to do your own research and get the necessary consent to avoid an enforcement notice, which may force you to rebuild what you have demolished!
