| Show A MAMMOTH OFFICE BUILDING DISSECTED we are arc much more apt to be impressed by a building that exceeds all others in point of 0 height rather than bulk mainly because our eyes are constructed to take in only the superficies of an object and hence give us but an inadequate conception of its cubical content for instance it is not half so sensational to state that the coal consumed by a transatlantic liner in a single till would occupy a bin CO 60 ft square and 50 ft fl deep as to state that a train over a mile long would be required to cart this amount of coal from the mines to the vessel gain again the gibat pyramid of choops which Is the bulkiest bul kiest kielt monument built by man inan Is frequently used as a unit by which to show tile the enormity of our annual crops oil our output of coal the production of iron and the like but frequently this results in tilling filling the reader with aston I 1 a at t the hugeness of the pyramid itself rather than impressing him with the enormous bulk of the product compared therewith public interest in large buildt buildings figs has been so occupied with the loftiness of metropolitan and singer towers in recent years that other buildings much larger when their ehtee dimensions are considered have receded hed practically no attention for example the city investing companas Comp anys building though many times bulkier than the towers just referred to has been almost completely overshadowed by the neighboring singer because the he latter leuchts up till a hundred odd feet higher Io Ilo iowne woe weier the tower type of building lias has about reached its limit ft height not on account ot of any structural but because the revenue from offices hardly provides sufficient return on oil the original in vestment for this reason the skyscrapers ot of tile the future will have to be wide and deep as well as tall our sky piercing cing towers have established the but the real work of raising tbt sky line of new york will be done by the large bu that I 1 are growing up to these recoil heights licis lits it Is only fair that these huge though not so tall buildings should receive recognition 1 the largest office bui building bring riba now ill bourst of c construction is an annex to the Whit whitehall chall null dins on battery place the original structure I 1 Is only twenty stories high but the ar annex me is to to consist of thirty one stories s and will rise to a height of feet the curb while this Is about ta 5 feet leas than the ai extreme renie height of the city investing building it represents a larger rental capacity allen ft hen combined with the old building the office space in the two being square quare feet or more than in any other building in the world tire annex is built on oil a plot of sl ajla square feet and the total cubical capacity ot of the building exclusive of the foundations will be cubic cobic feet before commencing tile the actual con st ruction ot of the building it was necessary to excavate cubic yards of earth this is equivalent to digging a narrow ch C tian h IS feet wide and 6 feet deep all ane t ie way front from the battery to madison dison in order to convey an all adequate idea of 0 tile the tremendous proportions proportion i ot of tills this building our abst ai has dissect ted led the structure and assembled the principle materials about tile the madison square garden and tower as shown on the hout page illustration the structural steel work tons has bon bui built it up tip into inta t t single gilder of standard proportions 19 feet square the metal being correspondingly despondingly ly heavy and tills this extends extend to a height ot of feet the girder compares jaora adorably aora bly with the mad madison square tower lq conati the walls ot of the guilding luil building ding seven and a halt half million common brick will vill be used and these it built up tip into the forni form ot of a brick of stan standard aard proportions would completely overshadow madison square garden in a addition to the common brick 1 face brick will be required in the baiad ing as well as tons of ornamental terra cota and the latter into a single capital would occupy the dimensions ghen in the illustration within the building there will be I 1 tOrtO li square feet ol of partition tile and square feet ot of column covering barrels of portland cement ceni tnt will be used the cinder fill III for the floors will be about halt half a million cubic feet which it put into a rural sidewalk of standard dimensions would reach nearly all the way irom from new york to philadelphia it is astonishing how much glass Is required in the building it if made alo a single sheet it would cover square feet or more than an acre and a half even such a thing as tile the window weights is an enormous item as will ill be evidenced by comparing the huge window weight in the illustration with the man shown at the right hand band side while modern office bull buildings dings are constructed of fire proof materials a certain amount of wood Is absolutely necessary for the floors doors alone of the whitehall anne annece SOO board feet of yellow pine will be required while for the base molding shioo feet will be used to heat the building sq fert cot of rad radiator fator surface will be furnished and if a single radiator were made to provide this amount of radiating surface it would rise almost to a level with the root roof of the madison square garden the boiler equipment of 0 the building will consist of horsepower horse power and the engines of 2000 horsepower horse borse power the combined can dle die power of the electric lamps will be and will be ba over 3 electric fixtures with 65 miles of conduits and wiring ten miles of oc plumbing will be necessary and 20 miles of steam pipes while these are only a few of the items required in the construction and equipment or of the building they stif suffice fice to show that a large structure may possess a great deal of 0 interest quite apart from its height scientific american |
