CN ORE DOCKS

Krech Ojard has performed the underwater inspections, design of structural repairs and modifications for the Canadian National Railway’s* (CN’s) three ore docks in Duluth and Two Harbors, Minnesota for the last twenty years.

These massive CN Ore Docks are typically founded on pilings and enclosed with a sheet pile wall. Repairs and modifications over the years included grouting of the concrete foundations to reestablish pile bearing, replacement of sheet piling, reattachment of sheet piles, design and construction of twenty feet wide fender extensions to accommodate the loading of 1000 ft vessels as well as numerous modifications to the material handling systems.

More recent projects at the CN Ore Docks include the design of hundreds of new support slabs for CN Dock#6 in the Duluth Harbor.

*Prior to the CN’s ownership, these docks were owned and maintained by the DM&IR Railway.
