Project planning
The project required detailed planning due to the proximity to the coastline and fluctuating groundwater levels. Dewatering systems were strategically positioned to control water inflow.
Problem solving
Managing groundwater was a key challenge throughout the project. Dewatering pumps were installed and repositioned as excavation progressed to maintain dry working conditions.
Documentation
Required SWMS, dig permits and safety documentation were completed and communicated to the work crew.
Sustainability
Dewatering discharge was managed responsibly to prevent erosion or environmental impact to surrounding areas.
Challenges
Groundwater & Tidal Influence
Dewatering equipment was positioned strategically to manage inflows and maintain safe trench conditions.
Dewatering Equipment Placement
Pumps, suction lines and discharge systems had to be positioned effectively to ensure continuous operation.
Deep Excavation Stability
Deep sewer installation required careful excavation techniques in sandy soils to prevent trench collapse.
Adverse Weather Conditions
Close coordination between operators, supervisors and ground crews.
