| New approach to demolition A new approach to demolition is the deconstruction of a building with the goal of minimizing the amount of materials going to landfills. This "green" approach is applied by removing the materials by type material and segregating them for reuse or recycling. With proper planning this approach has resulted in landfill diversion rates that exceed 90% of an entire building and its contents in some cases. With the rising costs of landfills this method is usually more economical than traditional demolition, and contributes to a healthier environment.[citation needed] Examples of this can be found on http://www.greenrecyclingnetwork.com. The development of plant and equipment has allowed for the easier segregation of waste types on site and the reuse within the construction of the replacement building. On site crushers allow the demolished concrete to be reused as type 1 crushed aggregate either as a piling mat for ground stabilisation or as aggregate in the mixing of concrete. Timber waste can be shredded using specilist timber shredders and composted, or used to form manufactured timber boards, such as MDF or Chipboard. Safety should always be paramount. A site safety officer should be assigned to each project to enforce all safety rules and regulations. |

Demolition Misconceptions |
| 1. Demolition contractors primarily implode, or "blow up" buildings | Implosions account for less than 1 percent of all demolition work |
| 2. Demolition contractors destroy many structures that should be saved. | Demolition contractors are instrumental in achieving the goals of preservationists. |
| 3. Demolition contractors don't participate in the nation's recycling effort | The demolition industry was salvaging building elements and materials for reuse long before it was the "ecological thing to do." |
| 4. Demolition contractors unnecessarily overcrowd landfills with debris | The industry is reducing its use of landfills in favor of recycling |
| 5. Demolition is an unsophisticated business | A safe and successful demolition project requires a working knowledge of both construction and the law. |
| 6. The methods of demolition never change. Demolition practices today are not only quicker | Demolition practices today are not only quicker, but safer and more cost-effective |
| 7. One demolition contractor is basically the same as the next. | Don’t tell that to the owner who has had the misfortune of dealing with an inexperienced contractor |
| 8. Demolition is dangerous business | In the hands of professionals, the danger is controlled. |
| 9. Demolition is expensive | Commercial demolition work generally costs less than 2 percent of the replacement cost of the building. |
| 10 .Once a demolition project is completed, the owner's worries are over. | A project owner cannot "contract away" his responsibility or liability. |

Demolition From Wikipedia, the free encyclopedia
Demolition
is the opposite of construction: the tearing-down of buildings and
other structures. It contrasts with deconstruction, which is the taking
down of a building while carefully preserving valuable elements for
re-use. The tallest demolished building was the 47-story Singer
Building of New York City, which was built in 1908 and torn down in
1967-1968 to be replaced by One Liberty Plaza.
For all
buildings, such as houses, that are only two or three stories high,
demolition is a rather simple process. The building is pulled down
either manually or mechanically using large hydraulic equipment:
elevated work platforms, cranes, excavators or bulldozers.
Larger
buildings may require the use of a wrecking ball, a heavy weight on a
cable that is swung by a crane into the side of the buildings. Wrecking
balls are especially effective against masonry, but are less easily
controlled and often less efficient than other methods. Newer methods
may use rotational hydraulic shears and silenced rock-breakers attached
to excavators to cut or break through wood, steel, and concrete. The
use of shears is especially common when flame cutting would be
dangerous
New approach to demolition
A
new approach to demolition is the deconstruction of a building with the
goal of minimizing the amount of materials going to landfills. This
"green" approach is applied by removing the materials by type material
and segregating them for reuse or recycling. With proper planning this
approach has resulted in landfill diversion rates that exceed 90% of an
entire building and its contents in some cases. With the rising costs
of landfills this method is usually more economical than traditional
demolition, and contributes to a healthier environment.[citation

The development of plant
and equipment has allowed for the easier segregation of waste types on
site and the reuse within the construction of the replacement building.
On site crushers allow the demolished concrete to be reused as type 1
crushed aggregate either as a piling mat for ground stabilisation or as
aggregate in the mixing of concrete.
Timber waste can be
shredded using specilist timber shredders and composted, or used to
form manufactured timber boards, such as MDF or Chipboard.
Safety
should always be paramount. A site safety officer should be assigned to
each project to enforce all safety rules and regulations.
