4 Essential Considerations in Bridge Demolition

Demolition of a bridge means the destruction of a bridge. This is done in conditions like when the bridge gets old, damaged, and no longer needed at that place. Before the reconstruction phase, comes the demolishing phase of the bridge. This process includes several methods like explosive, mechanical, and hydro demolition. 

For the process of demolishing, the government hires the company which is expert in it. The company sends their workers along with machinery.

This is critical work which requires proper care. Many times, only some parts of the bridge are destroyed. So, to ensure the safety of bridge and workers, proper attention is required,

Here are the four essential considerations in bridge demolition:   bridge demolition

Analyze the condition of bridge

For bridge demolition, it is essential to carefully analyze its condition first. For this purpose, examine if the bridge has any cracks or corrosion issues. Along with that, it’s important to view the condition of the deck, beams, and pier. In this way, it will be easy to select the suitable abolishing method.  

A layman can’t analyze the material and structural condition of the bridge. A trained company or contractor can only do the proper inspection. 

Look Over the Suitable Demolishing Method

After analyzing the condition of the bridge, it’s easy to select the method of demolishing. There are various types of methods of demolition. Some of methods of bridge demolition are:

• Explosive demolition
• Mechanical demolition
• Dismantling of bridge
• Hydro-demolition

If the condition of the bridge is wrecked, then the most conventional method of controlled explosion is used. Mechanical demolition is also another conventional method. This way is preferred for small bridges.

There are some conditions where some parts of the bridge are in a good state. So, in this state only the destroyed parts are demolished with proper care. Whereas, hydro-demolition involves the high pressure water to demolish the targeted part.  

Manage the Traffic

The process of demolishing the bridge significantly disrupts the traffic. The cranes and other machinery causes the blockage of roads. Along with that, the waste material in the process of demolishing can also become a hurdle.

It’s important for the authorities to redirect the traffic in case of bridge demolishing. This process can cause accidents too. So, it’s important to keep the general public away. For this purpose, use the barriers and warning signs of constructions to block the way for the public.

Provide an alternative way to the people. In this way, flow of traffic and safety of citizens can be managed and ensured simultaneously. 

Consider the Potential Risks

For the safety at work, it’s important for the authorities to consider the potential risks. First of all thoroughly inspect the site to analyze the potential hazards. This process of bridge demolition includes the various risks like falling debris, machinery, and exposure to hazardous materials. 

By carefully analyzing the potential risks, it would be easy to manage it. Prevention is better than the cure. So, authorities should make sure that the workers are wearing the helmet and other essential protection things.
