The Future 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 authority 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 communities 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 development 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 developed. 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

Building demolition requires careful consideration of the following points.

• 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 deciding 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 debris 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 minimise 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 valuable 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 considerable 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.Crushing of the demolished building and stone to 6f2 grade recycled stone is an environmentally friendly option to disposal of the rubble at a landfill site.

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 expert 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 appropriate 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 crash into its own footprint.

Because of the risks 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 adequately 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 unplanned 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 disturbed will have to be informed.

These are some of the elements that go into the demolition process that an expert demolition company will have the expertise to put into place and gain the required planning approval.

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 dangerous 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.

Installing a Drip Irrigation System

If you are looking for ways to keep your garden watered without wasting too much time and money, you have probably gone through a lot of options in your mind. Maybe you have considered a sprinkler, a hose, or a good old-fashioned watering can. All of these methods might be convenient, but most of the time you will end up wasting water on plants that do not need any more. If you live in a drought stricken area like I do, you know that every bit of water counts. I ended up getting a drip irrigation system. I have not regretted this decision at all.

When you install a drip irrigation system, you can choose one of two varieties: above ground and below ground. The above ground version drips small amounts of water continuously onto the ground, and allows it to soak in such as the 4 pot wilma system self watering grow kit. It is all regulated from a pressure controller, which ensures that the water just comes out at a drip instead of a spray or a stream. These pressure regulators are very inexpensive. The whole drip system can be set up with a pressure regulator and a garden hose with holes poked in it (although it is ideal for you to get a pipe designed for this type of use, I have found that the hose method works acceptably).

The underground system is a bit more of a pain to install and maintain. But if you are really into the aesthetic aspect of your garden and do not want any visible watering system, then you might consider it worth it. It is essentially the same as the above ground version, only a small trench is dug for the hose or pipe prior to any planting. This allows the water direct access to the roots for the most watering efficiency. Plus, you can impress your neighbors by having a beautiful garden without ever going outside to water it! They will be baffled.

To choose between the two systems, you need to take several things into account. Do you have the same plant layout year round? If it is always changing, you probably will not want to bury your hose. It can be a pain to dig it up and re-align it with all your new plants every year or so. Even if your plant layout never changes, you need to consider how much you really mind seeing a hose in your garden. If it really bothers you to the extent that you are willing to work for a few hours to get rid of it, then by all means bury it. But otherwise I would suggest staying above ground if for nothing else than the convenience of repairing and rearranging.

One of the main advantages of the drip irrigation system is its efficiency. Instead of spraying large amounts of water willy-nilly like a garden hose does, it makes the most of your precious water by putting it exactly where it is needed. It can also provide your garden with constant watering, instead of just having to go thirsty whenever you are not around to water it.

So if you are looking for an easy, cheap, convenient, and efficient alternative watering method, you should go out to the gardening store today and purchase the necessary items to install a drip irrigation system. I think you will be surprised at how much easier it is to maintain a garden after you have it.

The Saxophone – A Favorite of Musicians

A favorite instrument among musicians is the Saxophone. It has the flexability to be played in so many different genres of music is amazing, and the saxophone adds variety to different kinds of musicians. Instrument Pro offers these beautiful instruments available to musicians at some of the lowest prices.

Blues, R&B, and ska groups welcome the saxophone with open arms because of its versatility and sometimes haunting sound. The saxophone can be used in complex melody lines or as background blending with other instruments for a comprehensive sound produced by the musicians. The sax is widely used in these ensembles because of its ability to respond to the improvisational player. Improvisation is a musical set where no formal piece of music is given to the musician. Instead the underlying chords or the melody is given and the player is to play music that compliments and enhances these “set” pieces or progression of chords.

When considering the idea of purchasing a saxophone, you should become informed about the different kinds of saxophones, those in the low price range as well as the high price range. Playing the sax at home for your own entertainment and that of family and friends will allow you to buy a low priced instrument. However, you always want the best quality for the amount of money you can spend. You should definitely research and comparison shopping.

When you are purchasing a sax for your kids as they learn to play, it may be best to get a good quality instrument in the lower price range and move up to a better instrument when they have really grasped the ability to play and have determined that they will be playing more in the forseable future.

Instrument Pro coupons make the price a a new saxophone all the more reasonable. Be sure and select a sax that produces good timbre and tone when it is played.

Investigating Crafty Bed Sheets

In some parts of the world, a second bed sheet is placed on top of the sheet that covers the mattress. This second sheet is referred to as a “top sheet.” When this top sheet is put in use, the sheet directly on the mattress is referred to as a “bottom sheet.” A sleeper lies between the two sheets. Blankets, comforters, and any additional bed covers are put above the second bed sheet.

When I shop for new sheets I always look for the ones with a thread count of at least 300. What the thread count determines is the comfort of the fabric. A good rule of thumb is that the higher the thread count number, the softer the sheets will be. How many of us at some time or another have slept on scratchy sheets or those that are so thin you can almost see through them. We spend a long time asleep during out lifetime so it’s really important to make our sleeping experience as pleasant as possible. That is what sheets are like.

Bed sheets are available in two types: flat and fitted. A flat bed sheet is nothing more than a rectangular-shaped piece of linen. A fitted bed sheet features four corners with elastic bands around the edges and is used as a bottom sheet. A reason for using a fitted bottom sheet is to prevent it from slipping off of the mattress while the sleeper moves around on the bed. A unique method of folding and tucking while making up a bed is referred to as “hospital corners,” and this is typically employed when the bottom sheet is flat as opposed to fitted. This is what sets are like.

Remember, bed sheets are a critical factor in feeling the quality of your bed, and as we spend on average one third of our life there, we may as well make it as comfortable as possible, so buy good quality linen.

Cotton is by far the most popular material because it is snuggly in the winter and cool in the summer (although they have to be warmed up in the winter first). There’s just something about sinking into a bed with high quality cotton sheets. In addition to being comfortable, manufacturers tend to produce them in more styles and colors (than other sheet types) to keep up with the consumer demand. This is what flannel sheets are like. What about you? Are you a cotton person or silk? Do you want a frivolous thread count, or will 250 do? Think about your options carefully before you shop for bed sheets and then enjoy your choice.
