Understanding Groundwater’s Impact on Engineering Construction

 

Groundwater is a significant factor that influences engineering construction projects, exerting effects on design, functionality, and overall costs. Its presence beneath the earth’s surface, stored in aquifers within rock fractures and soil pore spaces, can lead to various challenges during and after construction.

During construction, groundwater can impact the project in several ways:

1. Foundation Stability: Saturated soil resulting from floods or high groundwater levels can weaken the foundation’s stability, leading to cracks and structural damage.
2. Soil Strength Reduction: Rising groundwater levels can decrease soil strength, potentially causing slope failures and compromising the integrity of the construction.
3. Unstable Excavation: Groundwater seepage into excavated areas can destabilize the site, leading to safety hazards and construction delays.
4. Cost Overruns: Dealing with groundwater-related issues may lead to unexpected expenses and project delays, affecting the overall construction budget.

Post-construction, groundwater can continue to pose challenges, including:

1. Structural Damage: Cracked walls, uneven floors, and wet basements can result from prolonged exposure to groundwater, impacting the building’s durability.
2. Health Concerns: Mold growth and water leaks in damp environments can pose health risks to occupants and require costly remediation efforts.

Identifying and evaluating groundwater conditions during construction is crucial. Methods include:

1. Site Reconnaissance: Site visits and imagery interpretation help assess water table conditions, providing initial insights into groundwater presence.
2. Subsurface Investigation: Test pits and soil sampling help define groundwater levels and characteristics, particularly in cohesive soils where water flow is slower.
3. Monitoring Instruments: Piezometers and transducers track groundwater pressure changes over time, providing real-time data for informed decision-making.
