Civil engineers and Structural engineers.
Because of cracks and corrosion. Actually, poor maintenance is the cause of ALL modern bridge failures and closures.
The corrosion of iron weakens the structural integrity of buildings and infrastructure over time by causing the metal to degrade and lose its strength. This can lead to structural failures, such as collapsing beams or bridges, posing a safety risk to people and property. Regular maintenance and corrosion prevention measures are necessary to ensure the longevity and safety of structures.
Present the main reasons that cause strategy failures, and what strategic decision can be taken to prevent such failures.
Structural strength.
Flooding: Excessive water accumulation due to heavy rainfall or snowmelt can lead to flooding, damaging properties and infrastructure. Erosion: Water can erode soil and rock over time, causing landslides, sinkholes, and loss of land. Corrosion: Water can corrode metals and weaken structures such as bridges, pipes, and buildings, leading to structural failures.
