Building Superintendence For Steel Structures; A Practical Work On The Duties Of A Building Superintendent For Steel-Frame Buildings

BUILDING SUPERINTENDENCE FOR STEEL STRUCTURES - A PRACTICAL WORK ON THE DUTIES OF A BUILDING SUPERINTENDENT FOR STEEL-FRAME BUILDINGS AND THE PROPER METHODS OF HANDLING THE MATERIALS AND CONSTRUCTION by EDGAR S. BELDEN. INTRODUCTION: THE problems of superintendence of steel frame structures aie JL so different from those which arise in connection with other types of buildings that it has been necessary for men to make a specialty of building superintendence for steel buildings. The knowledge of the best types of design, the proper methods of fabrication, the tests which should be connected for quality of steel, and finally the proper methods of erecting the steel, all call for special training apart from the usual building superintendence methods. It is with the idea of giving engineer and layman the most authoritative information on this important subject that this little volume has been published. It does not attempt to go into the theory of design of steel structures, but confines itself to the problems of superintendence alone. The author is abundantly quali- fied to speak on this subject as he has erected many steel buildings for one of the biggest contracting firms in the country. He has given the reader the benefit of his experience as a superintendent by outlining the duties of this office, and making clear the engineering, legal, and practical knowledge required. Then he goes into detail regarding the inspection of the steel material in the fabrication shops and the proper method of storing it until needed. The problems of erection are all treated equipment required, foundations, the handling of the steel, riveting, and painting. The author closes the article with some advice as to the proper organization of his force, how the superintendent should work with architect and owner and what qualities a good superintendent should possess. Altogether the article should prove a valuable addition to the technical literature in this field.
