Foundations for the New Singer Building, New York City
In August, 1906, the Singer Manufacturing Company awarded a contract to The Foundation Company of New York City, for sinking the pneumatic foundations of the addition to the old building on the northwest corner of Broadway and Liberty Street, now known as the Singer Tower. This contract was for a lump sum, on the basis of the foundations being carried down to 70 ft. below the curb, or approximately to the average depth of the top of the hardpan as shown by the borings; for so much per cubic yard for everything between the depths of 70 and 75 ft.; and for an additional price per cubic yard for everything below 75 ft. The price to be deducted in case the depth of 70 ft. was not reached was about one-half of the price to be added. The progress reports of each caisson, given in Table 2, Plates IX and X, will show the justice of this proportion. The contract stipulated that the work should be completed in 110 days on the same basis of depths.
