As Mombasa residents prepares for the controlled demolition of a sinking 9-story building in Fayaz Estate, many may be wondering about the process involved in such operations.

Controlled demolition is a highly specialized and carefully planned method of dismantling buildings and structures, offering a safer and more efficient alternative to traditional demolition techniques.

The Kenya Defence Forces (KDF) are leading the operation, following a formal deployment authorized by Defence Cabinet Secretary Roselinda Soipan Tuya.

Mombasa Governor Abulswamad Nasir has expressed gratitude to residents for their cooperation, emphasizing that the county is taking all necessary precautions to restore normalcy.

But what exactly is controlled demolition, and why is it preferred in certain situations?

Controlled demolition involves the strategic use of explosives or other techniques to collapse a structure in a precise and predictable manner. The primary goal is to minimize risks to surrounding areas and ensure the safety of people and property.

Key aspects of controlled demolition include:

• Purpose: Controlled demolition is used when traditional methods of demolition are not feasible or when a high degree of precision and safety is required.
• Methods: Techniques range from implosion, which uses strategically placed explosives to cause a structure to collapse inward, to specialized equipment for carefully dismantling sections of a building.
• Safety and Precision: Minimizing risk is paramount, with careful planning and execution to protect people and surrounding structures. Environmental impact is also a key consideration, with measures taken to control dust, debris, and vibrations.
• Applications: Controlled demolition is frequently used for high-rise buildings in urban areas, bridges, towers, and structures in sensitive environments where precision and minimal disruption are essential.
• Preparation: Site preparation for demolition by explosive means is detailed and thorough, regardless of the method of demolition, and can take from a few days to several months depending on the structure. This includes extensive surveys, structural analysis, and careful placement of explosives.

While controlled demolitions offer numerous advantages, it’s important to acknowledge potential drawbacks. Concerns about noise, dust, and temporary disruptions are valid. However, these are typically mitigated through careful planning and community engagement.

As Mombasa moves forward with the controlled demolition of the sinking building, understanding the science and safety measures involved can help alleviate concerns and foster greater public confidence in the process.

The operation is being carried out in close coordination with the County Government of Mombasa, the National Police Service, and the National Youth Service (NYS), ensuring a collaborative approach for effective execution of the task.
