The Process of Demolition

Introduction

The definition of the word ‘demolish’ is deliberate and controlled collapse of a structure. In the late 1970′s Fred Dibnah became the most famous steeplejack in Britain when his work on demolishing tall chimneys without the need for explosives was shown on Television. Fred was an expert on repairing tall chimneys, so when it came to taking them down he knew just how to do it. He would cut an alcove at the base of the chimney, and then place wooden props to support the structure. By carefully positioning the props, the chimney would collapse in the right direction when the wood was set alight and burned away. Once he was nearly crushed when he miscalculated demonstrating how dangerous demolition work is.

The actual word to demolish only came into being in 1570, and was used after that to mean the deliberate taking down or destroying of a building or structure. Although in fact the process of demolition in some form or other has been occurring for thousands of years. Buildings have been destroyed either by natural disturbances of the Earth’s crust or during battles or attacks on villages for as long as there have been structures. The remaining ruins would be removed and rebuilt or used for other buildings nearby and must be the first examples of recycling.

Preserving the past – preparing the future.

To preserve Britain’s history of agriculture the land between built up areas of the villages and towns is protected from expansion of urban sprawl. This land is known as Green Belt and is preserved for farming which is vital to the continuing economy of the country. By containing the Green Belt, urban areas are squeezed to provide housing, so developers have to be more creative to find suitable sites.

Britain is a country with a very dense population per square mile. The amount of land available for construction is limited compared to other countries. Therefore there is always a high demand for space on which to build. Taking down old and unused buildings and replacing them with new is one way to counteract this shortage.

Land that may be disused industrial and commercial sites, but could be contaminated with hazardous waste or pollution, are called Brownfield sites. Once the land has been cleaned up they are potentially valuable for redevelopment. Both Glasgow and South Wales created gardens out of old industrial sites and put in Shopping centres to attract visitors.

Greyfield sites are distinct from Brownfield sites in that they do not have the environmental concerns of toxic waste. The term greyfield comes from the large areas of asphalt which had once been car parks of commercial urban properties. Their value is in the fact that the infrastructure such as roads, electricity, water, sewage, and gas is already in place. These urban areas are underutilised or abandoned and are valuable because require very little remedial work to be utilised. Cities such as Leeds and Manchester have had a massive programme of converting the old warehouses or factories into apartments, shops and restaurants, retaining the original shell and refurbishing the interior into modern accommodation.

The Demolition process

Use the following basic checklist to confirm your demolition contractor is as skilled as they claim.

• The construction and size of the building.
• What items are valuable for re-use?
• How will the old site be re-used?
• How is the waste to be disposed of?
• Electricity water, sewage and gas mains.

Hydraulic excavators and bulldozers can be used to undermine the walls at the base, so that the structure will topple; at the same time controlling the manner and direction of the fall. Safety issues are paramount, and clean-up strategies are also taken into account when choosing how the building will be demolished.

Traditional Demolition

Once all the services were disconnected, the men and machinery would go in and just knock down the walls. The whole structure would collapse and the resulting wreckage would be piled onto lorries and disposed of in landfill sites. Concrete foundation would be broken up by pneumatic drills and the site would be cleared of rubbish. However today demolition practices are subject to strict planning, safety and monitoring regulations and are highly controlled by the local authority.

Deconstruction and Recycling

The new approach to demolishing buildings is known as deconstruction – a green approach. Landfill sites are in short supply so the aim when demolishing a building is to reduce the amount of waste remaining.

Small structures such as two or three storey houses can be dismantled quite easily. The work may be a painstaking task of dismantling by hand – brick by brick – or beam by beam but by going carefully expensive materials are preserved for re-use. The value of deconstruction is that 90% or more of waste is saved from going into landfill sites and reclaimed materials can be re-used and recycled for future buildings. The farmer opposite my house sold his barns in the farm yard for housing; when the builder demolished the barns he cleaned up the bricks and reused them for the wall around the farmhouse thus retaining the character of the farm.

Modern techniques and machinery allows demolition companies to efficiently segregate waste types on or off-site. Construction materials are recycled and re-used whenever possible in the new structure making substantial savings in project costs as well as being good for the environment.

Concrete can now be rapidly broken up with a new machine called a guillotine.Demand for 6f2 recycled material is on the increase as it provides a viable alternative to disposing of the demolished building remnants to landfill. It can also be used on site as a sub-base for any new buildings.

Copper pipes, lead, roof tiles or slates, floor tiles, wiring and doors, and wood panelling are valuable objects that are saved for recycling and re-use. Many specialist firms sell reclaimed old or antique building items in most towns and cities.

Tall Buildings

Tower blocks and chimneys are the type of tall buildings that may need to be demolished. The demolition of tall buildings necessitates specialist techniques. The tallest building to be demolished lawfully was in 1967/8 of the Singer Building in New York. The collapse of the World Trade Centre after the 9/11 attack in 2001 demonstrates the terrible devastation that occurs if the demolition is uncontrolled and haphazard.

In the demolishing of tall buildings and large structures a wrecking ball on a crane can be used, but is rarely practiced because the swinging ball is rather uncontrollable. The proximity of other buildings is a determining factor which prevents the use of explosives to implode a tall structure. So ‘High Reach’ demolition excavators are used where other methods are not suitable to demolish the top part of a tall building. Once it is down to a manageable height demolition can continue in the usual way. The various methods of demolishing tall buildings are by implosion using explosives, controlled collapse and piecemeal. To control the dust produced in demolition, water hoses and spray equipment are sometimes used and then it is called a wet demolition.

Explosions

The use of explosives in demolition is very specialist work and getting it wrong would be disastrous. If for instance there is atmospheric pressure from low cloud above the implosion site, the shockwave may spread outwards instead of upwards causing the wave of energy and sound to break windows. If an implosion is not prepared correctly the danger may be damage to surrounding buildings where flying debris may cause injury to spectators.

For many people when they think about demolition they may have in mind the use of explosives in the dramatic collapse of a tall building. This process is actually called implosion using explosives. Implosion is essential for dense urban areas as it brings down a tall building so that the surrounding environment is damaged as little as possible. The collapse takes only seconds for the building to drop into its own footprint.

Because of the dangers of working with explosives they will only be used when other methods are too costly or impractical. Where there is a partial collapse of a building and there are still primed explosives that failed to go off, workers are in great danger because the remaining structure is highly unstable. At the same time the demolition has to continue to secure the safety of the site.

Health and Safety

The work of demolition is a much more technical and complicated process than most people would appreciate. The job is highly dangerous and requires experienced and skilled operators to carry out the work. It is essential that personnel working in the industry are appropriately trained. Health and safety awareness is crucial in demolition services so it is advisable for operatives to have gained a Certificate of Competence in Demolition to ensure safety for both workers and public alike. All demolition work is regulated by the Construction, Design and Management Regulations.

Sequence of Demolition

An incorrect sequence of dismantling will result in premature collapse of a building because the stability of any structure is reliant on the interdependence of its component parts. Think of a house of cards and what happens if one of the supporting cards is removed.

There is a strict sequence of events before any demolition can take place. Councils throughout the country will have their own specific list for planning approval in their area, but a typical order would be as follows:-

• Provision of Information
Information must be provided about the construction of the structure to be demolished. Details of its previous use and the appropriate demolition methods to be used, including disposal of hazardous substances, have to be submitted by the demolition company.

• Survey of Demolition
A thorough survey of the site to identify any structural problems, as well as risks associated with hazardous or flammable substances, will need to be discussed in detail with the authorities. (E.g. A disused garage where petrol has been stored is a potential fire hazard so preventative measures will need to be taken).

• Preferred and Safe Method of Work
A reputable demolition company will be able to select the appropriate method of disposal showing the outline dismantling process. Planning is essential for assiduous monitoring. The authorities will require a detailed statement of the safety procedures to used, and all parties involved need to agree the methods before any demolition can take place.

• Preparation and Planning
Issues such as asbestos abatement, rodent baiting, dealing with hazardous substances, disconnecting utilities, and making safe any electric, gas or other services have to be shown in the planning stage. There is a lot of preparation to be done before even starting work on demolishing the building itself.

• Protection of the Public
Safety cannot be compromised so where there are heavily populated areas around the demolition site the protection of the public is paramount. Any health hazards will need to be assessed and temporary services arranged, and people inconvenienced will have to be informed.

The above sequence of demolition are prerequisites for a demolition company Nottingham to work through to gain planning for your demolition works.

Conclusion

The aim in demolition is to eliminate an unwanted house as safely and quickly as possible and in our modern environment efforts are made to recycle or re-use most of the old material. This is not a new idea although the word itself is relatively modern. On the borders between England and Scotland after the Romans left, a large part of Hadrian’s Wall was hauled away and use was made of the beautifully dressed stone to construct the new buildings in the towns and villages nearby and some are still standing today.

Demolition work by its nature is a very risky business and demolishing any building is a complex and skilled process. Next time you see demolition work occurring on a building give a thought to the people who work in a dangerous situation daily and how much is involved in the meticulous planning, regulations compliance, care and skill that goes on to carrying out the project to clear the way for our future.

Home-Based Business Owners Can Save Thousands on Their Taxes

Do You Qualify For Home-Based Tax Deductions? Recent tax law changes have made it easier than ever to claim Home Office Deductions and keep more of what you earn.

If your home is a place of business, many of your personal expenses can be deducted as business expenses resulting in lower taxes. Using online tax preparation software can help you take all the deductions you deserve. To find which program is best for you, read an online tax software review and compare the features you need.

You may be thinking, “I have an Accountant/CPA/Tax Preparer who knows all about tax deductions so I don’t have to know anything about them.”

There are several reasons why that thinking could be costing you thousands of tax dollars. Some of those reasons are:

 

 

 

 

1. Most Accountants/CPA’s/Tax Preparers do not “specialize” in Home-Based Businesses and do not keep up with the ever-changing laws pertaining to them.
2. You are ultimately responsible for knowing what you can and cannot deduct as business expenses. Why? YOU are accountable to the IRS for your deductions, not the tax preparer.
3. If you pay someone to do your taxes you still need to know what you can deduct so that you can gather all relevant paperwork.
4. The most compelling reason: Getting the greatest benefit from your deductions. In a TurboTax review, it was found that most people saved an average of 15% when using a tax software program and their own research.

To qualify for these deductions you must meet 2 conditions, which most, if not all, Internet Marketers meet:

Condition 1: Do you work as an Internet marketer out of your home (on your “home computer)? To qualify for deducting expenses related to using a workspace for business in your home, your home must:

 

 

• Be your “principal place of business ” or you must use the space only to earn your business income.
• Be used by you on a regular and ongoing basis to meet your clients, customers, or patients.

AND

Condition 2: Are you in business to make a profit? Whether you made a profit or not is immaterial. Even if you lost money but intended to make a profit these deductions are still available to you.

If you answered yes to both of these questions then you do own a Home-Based Business and as such you are qualified to deduct Business Assets, Direct and Indirect Expenses.

Business Assets include business equipment such as computer, fax machines, business furniture such as desk (your dining room table for instance), desk chair and filing cabinets. These are 100% deductible if they are used “exclusively” for business purposes. A tax software program can help you find all the deductions you deserve using an interview process. In a H&R Block TaxCut review, it was revealed that people using tax software with an interview process could often find 20% more deductions than their own CPA or accountant. After all, you know your business best.

If these assets are not used “exclusively’ for business the amount you can deduct is proportionally related to how much these things are used in your business. It is possible to deduct a portion of your living room, sofa, DVD player etc if you meet certain conditions.

Direct Expenses are those directly related to conducting your business. This would include office supplies, telephone service,, cellular phones, ISP service, hosting, advertising etc. Direct expenses are generally 100% deductible.

Indirect Expenses include such things as rent on your home, utilities including heating and air conditioning and general repairs such as replacing a roof or repainting the exterior of your home.

These are authorized legal deductions passed into law specifically for Home-Based Businesses by Congress.

If you use your home for business purposes, many of your personal expenses can legally be converted into deductible business expenses including utilities such as heat and electricity, cleaning materials, house insurance and property taxes.

Learn all you can about what you can deduct, find a good tax software program, and you will consistently save thousands on your income tax each year.
