Demolition is the tearing-down of buildings and other structures. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for re-use. This work is common in the area of Miami Fort Lauderdale Florida where there are many companies responsible for this.
For small buildings in the area of Miami Fort Lauderdale Florida, 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.One thing about construction projects in Miami Fort Lauderdale Florida like houses and buildings is that just as they went up, someday they must come down. Nothing lasts forever, and that includes residential homes and buildings, as well as commercial structures.
When that day arrives and the building has become unsafe or just seen better days, it’s time to call in the building demolition experts. Every safe and successful demolition begin with the company you hire to carry it out. After you’ve hired a qualified and reputable company in Miami Fort Lauderdale Florida to do the job, the demolition process begins.
There are many different factors involved in a building demolition and several different ways to go about it. In the beginning, a demolition company must assess your specific needs so they can customize a demolition plan for your particular project. Building Demolition Miami Fort Lauderdale Florida
Once your needs are determined, a plan is created. The plan will include how the demolition is to be carried out, as well as all of the equipment that will be used to do it. The ultimate goal is to get that building demolished in the safest and most efficient way possible while staying within budget. These decisions will depend on things like the size of the building, the building materials, the reason for the demolition and the location of the building.
Some of the demolition methods that might be considered in the area of Miami Fort Lauderdale Florida include:
Once the plan is set, the demolition company will know the method, the equipment that’s necessary, the approximate cost, how much debris there will be, how it will be dispersed at the site and how long it will take to clean up. Backup plans and emergency plans will also be part of the overall demolition plan.
Obviously, it isn’t possible to just stroll into any city or town and demolish a building without getting the proper permits. Removing any building from a site will alter the landscape and can even alter property values and property taxes in the area. Building Demolition Miami Fort Lauderdale Florida
After the plan has been discussed and finalized, the company must get any and all necessary permits, so they are safe, and within the boundaries of the law when the demolition is carried out.
Preparing the Site
Just as you don’t just demolish a building without the proper permits, you don’t do it without preparing the site, either. Whether it’s a small house or a huge office building, site preparation is an important factor.
The building must be completely cleaned out, all of the utilities like gas, water, and electricity as well as the removal of any hazardous materials must be addressed, and any recyclable materials must be removed. Any reputable demolition company is well versed in all aspects of the demolition process, so site preparation is just another step.
After it’s all planned and the legal aspects are covered and the site is ready, the demolition is scheduled and carried out. To some people, seeing a building demolished is a thing of beauty. The coordination and expertise that goes into pulling it off just right are truly staggering. In a lot of ways, the building going down isn’t really an ending, but a new beginning for whatever structure is going to take its place. Building Demolition Miami Fort Lauderdale Florida
This section describes common ways of bringing down buildings in Miami Fort Lauderdale Florida. In practice, more than one method can be used to demolish a building.
Hand demolition is not a quick method and common for the companies in Miami Fort Lauderdale Florida because only hand tools are used. However, cranes and shear legs may be used to hold or lower beams during cutting. Chutes or crane-and-skip are usually used to get debris safely from the upper stories to the ground.
Safe access must be provided. If work cannot be carried out safely on the building, a scaffold or machine-lifted platform should be used. Building Demolition Miami Fort Lauderdale Florida
Demolish only one storey at a time. It is usually safest to demolish the building in the reverse order to building it, so the roof should go first. Next, part of each floor is taken out so that the debris can fall through. On some jobs, the debris can be dropped down the lift shaft, in which case, guardrails must be provided around openings.
Debris must be removed regularly and not allowed to pile up on floors. An overloaded floor could collapse onto the floor below, which in turn, could collapse on the floor below it. Without propping from the floors, the walls of the building could collapse. Walls could also collapse if debris is piled against them.
If people have to work in a place with a fall risk without guardrails or barriers to isolate them from a fall, other protective measures must be implemented, including wearing a properly anchored safety harness. Harnesses are only to be implemented if all other controls cannot be used. The employer shall need to undertake a hazard assessment to effectively determine the appropriate controls beforehand. All persons using any fall arrest systems must be fully trained in the correct and safe use of this equipment. Building Demolition Miami Fort Lauderdale Florida
Most structures can be demolished by balling, but it is a skilled practice that cannot be self-taught.
Balling is a viable and effective method of demolition in Miami Fort Lauderdale Florida when demolishing multi-storey structures that have suffered structural damage, where all other methods have been considered, and a hazard assessment has determined that this method is the most appropriate.
Hazards associated with this demolition method in the area of Miami Fort Lauderdale Florida include, but are not limited to:
Balling is hard on the machine: not all cranes can swing and control a demolition ball safely. Converted drag lines are the best machines for this work as they are robust and stable. Cranes with hydraulic rams must not be used for balling. Building Demolition Miami Fort Lauderdale Florida
Cranes used for balling should be fitted with a FOPS cab and should be enclosed, strong and debris-proof. Cranes used solely for lifting on a demolition project need not be fitted with a FOPS cab; however operations that could cause flying debris should not be carried out close to the crane.
Hydraulically-operated excavators and loaders can be fitted with various attachments for demolition work. Excavator buckets, boom-mounted hydraulic percussion breakers, and pusher arm equipment have been successfully used with these machines.
The main advantages of such machines are that they are extremely mobile, have a high output, and are able to work on vertical faces and floors above standing level, for that many companies are using this kind of machine in Miami Fort Lauderdale Florida. Their disadvantages are that the machines need adequate access, a firm and relatively flat base to work from, and can only work within the reach of their booms. To operate these machines efficiently, the length of the boom when fully extended should be at least 1.5 meters above the height of the building being demolished. Building Demolition Miami Fort Lauderdale Florida
The pusher arm method is not suitable for large buildings on confined sites, but it is good for masonry infill structures. The building is pushed over in stages by a horizontal force from the machine. An arm is fitted to the lower boom instead of a bucket. The arm is extended forward against the facing wall and the force of the excavator pressing forward provides the push.
This method requires engineering expertise to decide which key structural members should be cut or removed to cause a collapse. Once this method has begun, it is likely the structure will remain unstable until it is down. This method is best suited for bridges, silos, chimneys and structures on isolated or heavily controlled and secure sites; and in Miami Fort Lauderdale Florida it is too common that companies use it to that kind of structures.
A survey may be required to give the height and radius of the structure so that the fall area can be properly ascertained and protected to prevent unintentional entry during the collapse. Building Demolition Miami Fort Lauderdale Florida
This method is a form of deliberate collapse. Cables and wire ropes are fixed to key structural members and then pulled down by tractors or winches. It is suitable for detached buildings where there is plenty of surrounding room. The method can be used for timber-framed buildings, bridges, brick, masonry or steel chimneys, and for spires and masts. In Miami, Fort Lauderdale Florida is common that companies dedicated to the service, employ this method of demolition
Implosion or explosion deconstruction is an effective and efficient method of deconstruction employed in Miami Fort Lauderdale Florida, and can reduce both cost and time to bring dangerous multi-storey structures to the ground in comparison to conventional demolition methods.
This is a method favored in the United States to safely and quickly demolish structures where significant hazards are posed to persons through exposure during the demolition process. In most cases, the building is stripped to structure to allow for clean blasting; however in many cases, where the risk to personnel is high, this is not necessary.
In many cases, implosion can reduce the demolition period by up to 80% with the majority of time being spent in both the preparation period and the clean-up the following implosion. Building Demolition Miami Fort Lauderdale Florida
Demolition by explosion/implosion is a job for the expert. In New Zealand, HSNO restrictions and requirements for this method must be followed. Any inquiries should be directed to your nearest Department of Labour office.
Most structures, except timber-framed and brick structures, can be demolished this way. Even structures that have been previously compromised can be effectively demolished in this manner; however, the implosion expert will give instructions on any collateral damage that may occur.

The usual method is to cut or disintegrate key structural members by loading drilled holes with explosives, or fixing plaster charges to the outside of these members.
Power shears may be used to crop and cut through concrete and metal such as reinforcing steel or beams, particularly where there might be a risk of fire, or where the most precise cutting of a torch is not required. An additional feature is a reduction in noise onsite. Care should be taken to ensure that any member to be severed is either effectively supported or if to be allowed to fall, will not endanger remaining structures or personnel. Building Demolition Miami Fort Lauderdale Florida
Power grapples may be used to handle waste material, either to move it about the site or to load other vehicles when disposing of the waste. As some debris resulting from demolition has a high density, care should be taken to avoid overloading the equipment. Damage to the equipment itself should be avoided. Avoid the risk of the machine overturning as a result of instability induced by a heavy load. Building Demolition Miami Fort Lauderdale Florida
At all times, the machines should only be operated in strict accordance with manufacturer’s recommendations.
Other methods which are used in Miami Fort Lauderdale Florida, including thermic lances, drilling and sawing can be used in conjunction with the methods outlined in this section. These are specialized uses, and must be carried out only by fully trained and competent personnel. Building Demolition Miami Fort Lauderdale Florida
