The coffer-dam will be a solid concrete wall, six feet broad and eighty feet deep, extending eighty feet to solid rock. This will be the largest ofllce building yet constructed. It will weigh over 200,000 tons as against the weight of 103,000 tons of the Woolworth building, 188,500 tons of the Municipal building, and 82,500 tons of the Singer building.
