months of April andOctober is the task which has con-fronted the steel erector on theEmpire State Building in New YorkCity.Eighty per cent of this,totaltonnage was in place on Aug.1,when the building had reached toabout the 50th story.During July22 stories of steel were placed in 22working days,involving regularhours and no night work.As prog-ress has averaged about 10.000 tons  \nFIG.1—EMPIREof steel per month(working five8TATE BUILD.days a week).it seems probable thatINO,NEW YORKthe difficult schedule will be met.CITYThis article is devoted to an ac-count of the steel erector's methodsand equipment which are of interest and value bothbecause of the magnitude of the project and the care-ful planning and control which has been exercised.The steel tonnage in the Empire State Buildingexceeds by a large margin that used in any comparablestructure.The Chrysler Building utilized 21,000 tonsand the 70-story Manhattan Company Building,both inNew York City,required 18,500.tons.The Merchan-dise Mart in Chieago,recently characterized as theworld's largest building,required only 38.000 tons.Theprincipal roof of the Empire State Building is 1.043 ft.above the curh,and latest plans contemplate the additionof a combination airship mooring mast and observationtower approximately 200 ft.tall above this point.Thebuilding's completed height will exceed that of theChrysler Building,now the tallest stfucture,by some-thing over 200 feet.  \nIn preparing a plan of procedure for the steel erection,it was necessary to consider four major problems:(1)steel supply,which had to take into account the fabrica-tion schedule and methods of delivery;(2)plant layout,includling ntmber,size and location of derricks andhoisting engines;(3)steel-handling methods at the job,which necessarily had to be considered as complementaryto plant layout in the planning;and(4)actual erectionprocedure,including methods of setting,fitting up andriveting.  \nSteel Supply  \nThe large tonnage in the building and the urgencyfor completion made it advisable to divide the fabricatingcontract between two firms,the American Bridge Co.and the MeClintic-Marshall Co.Alternate sections fromthe basement to the roof,comprising from two to cightfloors each,were assigned to cach fabricator.All steelis shipped to a joint waterfront supply yard nearBayonne,N.J..and stee for erection is ordered from  \nAugust 21,1930  \nthis supply yard one lift(two floors)at a time,as needed.Because of possible delays in loading and shipment it isnecessary for the steelerectortoordersteeltwodaysin advance of the time it is to be used.Since there is nostorage space at the building site,it is absolutely neces-sary that everything be in readiness to erect the steelwhen it arrives.  \nSteel is delivered from the supply yard to docks onthe East River waterfront by derrick-equipped lighters.Columns and heavy members are transferred to trucks at23d St.while the smaller material comes ashore at 19thSt.Since the Empire State Building isbetween 331 and34th St.on Fifth
