The how of demolition

Demolition methodsIt is easy to demolish a small wall but for larger constructions demolition is not an easy job. There are various demolition methods. What method is used depends a lot on the area to be demolished, the purpose of demolition, and the way the debris will be disposed.

Some of the more traditional methods are Implosion, High Reach Arm, crane & ball. More recent and popular options are selective or strip out process of demolition.

Implosion uses explosives that eliminate the vertical structural supports. The building collapses due to the weight of the structure and the force of gravity. What counts here is the timing and the placement of the charge.

If the structure is more than 20 meters then the high reach method of demolition is used. This is a far safer method of demolition than the other traditional methods as the demolition operators can maintain a safe distance from the falling debris. This is because the excavators have a longer boom and arm that provides the distance. The high arm method also lets the operators have more flexibility in tight spots. Long-reach excavators allow operators to operate in cramped spots, while still achieving excellent precision.

The ball and crane uses a wrecking ball to demolish concrete structures. The ball can weigh up to 13,500 pounds. This heavy ball is either dropped onto the structure to be demolished or it is swung into the structure with enough force to break the concrete.

A very popular method used recently is the strip out method of demolition. This is popular as it allows reuse of certain materials as the complete structure is not demolished. This is a safe and cost effective measure to reuse secondary recyclable material. Focus Demolition  offers a number of demolition methods using the safer and newer means of demolition.



Designing energy efficient homes

well designed homesThe harsh summer heat can be quite tolerable if you keep a few pointers when designing a house.  You can get comfort and efficiency  just by the way a house is positioned keeping the environment in mind. Correct orientation can give you an efficient cooling and heating system without using up too much of energy.

East facing windows and doors get in a lot of sun which is welcome in winter but can be quite a pain during the summer months. These windows would require a different shading solution then a north facing window which would keep the room quite cool in summer but very cold in winter.

In climates where you need to keep the summer sun out and want the winter sun to penetrate you require passive solar heating. It is an energy efficient way of cooling during summer and heating during winter.

Another way of minimizing heat during summer and gaining heat during winter is by insulating the walls, roof and floors. Externally insulating materials like concrete, bricks etc are used to absorb and restore thermal energy.

Glazing windows to prevent heat loss is another way to maximize the use of energy in the house. Insulated glazing (IG) is a form of double glazing . In order to increase more heat the double window panes are separated by an air or other gas filled space.  Glazing can also be triple glazing to reduce heat transfer across a part of the building envelope.

In areas where there is little light you can use skylights to bring in more light and heat.

Incase of apartments and multi-story houses adding elevators can use up a lot of energy. Passive designing for a multi-storey unit can be quite a challenge as compared to individual dwellings. Getting someone to understand your exact requirement in the early planning stage can help save a lot of trouble later on.
