KKICK MASONRY 



Tins was one of the largest and most im- 

 l>cirl:iiil of all the contracts for the erection of 

 the building. It comprised principally the con- 

 traction of foundation wulls; all the common, 

 face and enamel brick masonry throughout; the 

 Belting of all exterior terra cotta; all terra cotta 

 floor and roof arches; terra cotta block fur- 

 ring for walls, columns and partitions; in short, 

 all filling in and encasing of the structural 

 sled framework and all anchors for masonry 

 work. 



The brick work was laid up in Atlas Port- 

 land cement mortar. 



The Tower walls are 12 inches thick at 

 the top and practically 40 inches at the base. 

 From the 14th to the 32d floor they are built 

 with a continuous batter on the outside face 

 amounting to $ of an inch per story. ( )n 

 account of this novel arrangement the floor 

 space inside the Tower is no less in the lower 

 stories than it is near the top, while the 

 shaft of the building has a slightly tapering 

 eU'ect. adding to its appearance of solidity and 

 stability. 



The floors and flat roofs throughout were 

 built of flat terra cotta arches, generally 10 

 inches in depth, "end construction" type. As 

 the floor beams in the Tower were spaced 4 

 feet on centers this resulted in very strong floors, 

 capable of transmitting the lateral wind pres- 

 sure, and adding greatly to the stiffness and 

 rigidity of the building, which, considering its 

 height, are remarkable. 



There were 540,000 terra cotta floor blocks 

 used, sufficient to cover an area of eight and one 

 third acres. 



Most of the partitions were built of 8-inch 

 by 12-inch porous terra cotta blocks, 2, 3 and 

 1 indies thick. The steel columns were furred 

 with similar blocks 2 inches thick. All outside 

 walls were similarly furred. There were about 

 875,000 of these blocks used. 



The entire masonry contract was executed 

 by John T. Brady & Co. of New York, with 

 Mr. J. P. Hutler and Mr. John Dordan of that 

 Company in charge of the work.
