Project Details
In September 2018 NSI was contracted to install a 30×30 28’ deep cofferdam for the installation of a new pump station. The installation had to overcome significant obstructions and a persistent high water table which required both a redesign and extensive energetic dewatering efforts. The pressures of the high water table required additional hydraulic bracing to ensure a safe excavation.
