Evaluate the potential consequences of uncontrolled settlement and how it can impact urban infrastructure. (5 marks)
Back
1. Structural Damage to Buildings and Foundations
- Impact: Uncontrolled settlement can cause differential movement, leading to cracking, tilting, or even failure of nearby buildings. Older structures with shallow foundations are particularly vulnerable to settlement-induced damage, which can compromise their structural integrity.
2. Disruption of Utilities and Underground Services
- Impact: Settlement can damage underground utilities such as water mains, sewer lines, and electrical conduits by shifting or fracturing pipes and cables. This results in costly repairs, service outages, and safety hazards, especially in densely populated urban areas.
3. Road and Rail Infrastructure Damage
- Impact: Uncontrolled settlement can create depressions or subsidence along roadways and rail lines, affecting transport infrastructure. This can lead to pavement cracks, uneven tracks, and dangerous driving or train conditions, necessitating repairs and potential traffic disruptions.
4. Increased Maintenance and Rehabilitation Costs
- Impact: Long-term settlement issues require continuous monitoring, frequent repairs, and rehabilitation, significantly increasing maintenance costs. If settlement damages critical infrastructure, it can delay project timelines and result in legal liabilities.
