Project Details
The NSI team has completed over 1,000 cofferdams for Underground Storage Tank (UST) installations. Each installation requires the erection of a bracing frame template to act as guide for sheet pile installation and to serve as formal bracing to keep the installed piles in place during the excavation.
Each project varies in complexity and engineering detail as exemplified in these photographs.
